TOOL SLIDE

Abstract

A tool slide, in particular a wedge drive, including at least one slide bed and one slide body. The slide body is arranged on the slide bed in sliding fashion with a prism guide, and a groove and a stud protruding into the groove are provided. Between the stud and the groove, at least one sliding element is provided. A driver that can be removed from the slide body is provided and between the slide body and the driver in the contacting state, there is likewise a prism guide composed of inclined elements of the slide body and corresponding inclined surfaces of the driver. Between the slide bed and the slide body, a prism guide or flat guide is embodied so that the sliding elements of the slide bed and corresponding sliding elements of the slide body are inclined relative to an x axis in a prism guide or are perpendicular in a flat guide. The sliding element has a wedge-like, inclined surface oriented toward the groove with which it rests on a corresponding surface of the groove wall and the corresponding groove wall has a corresponding wedge-like inclined surface so that an axial movement of the sliding element in a longitudinal direction reduces or enlarges a gap between the stud and the sliding element.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0062] A tool slide 1 according to the invention has a slide bed 2, a slide body 3, and a driver 4.

[0063] In the case shown, the slide part 3 is arranged so that it is suspended on the slide bed 2; the slide part 3 can be lifted up from the driver 4. The driver 4 is usually positioned on a first tool half (the lower one in the case shown), while the slide part 3 is positioned above the slide bed 2 on a corresponding second (upper) tool half (not shown).

[0064] The slide bed 2 is embodied as approximately box-shaped and has an elongated rectangular groove 5; next to the elongated rectangular groove 5, screw holes 6 are provided to accommodate corresponding screws (not shown). The groove 5 and the adjacent surfaces 7 delimiting the groove form a bearing surface for L-shaped slide strips 8, which rest on the surfaces 7 and extend into the groove 5 with one L-leg 9.

[0065] The L-shaped slide strips 8 have mounting holes 10 for screwing in mounting screws for insertion into screw holes 6. The L-shaped slide strips 8 have diverging surfaces 11 oriented toward the groove center with which they delimit a prismatic intermediate space between themselves.

[0066] Facing the walls 19 that laterally define the groove 5 and resting against them, the L-legs 9 have slide surfaces 22. The surfaces 22, relative to the thickness of the L-legs 9 between the groove side wall 19, extend along the longitudinal span of the L-shaped slide strips 8 in an inclined fashion so that the L-legs 9 are embodied as wedge-like or wedge-shaped. This inclined surface or wedge shape in this case extends at an angle of 1to 5. In a corresponding way, the groove side walls 19 are provided with a surface that is inclined relative to the longitudinal span so that a movement of the slide strips 8 in accordance with the longitudinal direction moves the surfaces 11 closer to or farther from the groove center.

[0067] Toward the slide body 3, the L-shaped slide strips 8 have slide surfaces 12, which are embodied as flat and are oriented perpendicular to a depicted x axis 13.

[0068] Toward the surfaces 12, the slide body 3 has corresponding slide surfaces or slide strips 14, which are embodied as sliding partners for the L-shaped slide strips 8.

[0069] Symmetrical to the vertical axis, a guide part 15, which is in particular embodied as a guide prism or dovetail, extends upward between the slide strips 14 and into the groove 5. In this case, the guide prism 15 has elongated prismatic surfaces 16 with which it rests against the surfaces 11 of the L-shaped slide strips 8.

[0070] Oriented toward the driver, the slide body 3 has other slide strips 17, which are inclined relative to the x axis 13 and correspond to prismatic guide surfaces 18 of the driver 4. The strips 17, because they are connected to the slide body, constitute liftable slide strips, which are brought into an operative connection with the surfaces 18 when the upper part and bottom part of the tool are brought together.

[0071] Since the guide surfaces of the L-shaped slide strips 8 and the corresponding surfaces 12 of the strips 14 are perpendicular to the x axis 13 and are also perpendicular to the guide prism 15, this embodiment is referred to as a so-called flat guide.

[0072] The inclined corresponding sliding elements 17, 18 between the slide body and driver form a so-called prism guide.

[0073] In another advantageous embodiment (FIG. 2, the same parts are provided with the same reference numerals), the tool slide 1 is likewise composed of a slide bed 2 and a slide body 3 (the driver 4 is not shown).

[0074] In the case shown, the slide part 3 is positioned on the slide bed 2 in suspended fashion; the slide part 3 can be lifted up from the driver 4. The slide bed 2 is approximately box-shaped and has an elongated groove 5. The groove side walls 19, which extend from the groove bottom, extend in converging fashion and consequently form a dovetail groove. The surfaces 7 delimiting the groove 5 converge toward each other. The surfaces 7 have L-shaped slide strips 8 resting on them, which extend into the groove with a narrow, short L-leg 9. The L-shaped slide strips have contact surfaces 11 oriented toward the surfaces 7 and have slide surfaces 12 oriented toward the slide body 3, which are flat and are embodied as diverging in an inclined fashion relative to a vertical axis. These surfaces 12 slide on corresponding slide surfaces 14 of the slide body 3.

[0075] The slide surfaces 14 of the slide body 3 are consequently embodied as inclined in roof-shaped fashion; the guide stud 15 or dovetail-shaped part of the guide stud 15 of the slide body is positioned so that in the middle, it is centrally situated in symmetrical fashion relative to the vertical axis; and the prismatic surfaces 16 are embodied as resting against the short L-shaped legs 9 of the slide strips 8. The surfaces 16 and 14 in this case enclose approximately the same angle as the surfaces 9, 12 and in the example shown, are approximately perpendicular to each other.

[0076] Since it is necessary to achieve an exact fit and guidance of the tool slide, particularly between the slide bed and the slide body, the guidance of the slide body in the slide bed must be adjustable or more precisely, the slide strips 8 and prism 15 must be adjusted relative to one another.

[0077] To this end, (FIGS. 3 through 6) the mounting holes 10 in the slide strips 8 are embodied as oblong holes so that the strips can be moved along the mounting screws 20 and thus along an adjustment direction 21.

[0078] The movement of the slide strips 8 along the direction 21 does not change anything yet with regard to possibly existing gaps or spaces between the surfaces of the slide strips 8 or L-legs 9 and of the guide prism 15. With regard to the longitudinal span or the directions 21, therefore, the contact surfaces 22 of the L-legs 9 of the L-shaped slide strips are wedge-like or wedge-shaped analogous to the first embodiment 8. This means that they change in thickness over their longitudinal span. The inclined surface has a slope of 1-5 degrees, for example.

[0079] The inclined contact surfaces 22 on the L-legs 9 of the L-shaped slide strips 8 are oriented toward corresponding surfaces 19 of the groove 5.

[0080] Because of the inclined surfaces 22, 19, a sliding along the direction 21 therefore causes the distance between the surfaces 11 of the L-legs 9 and the surfaces 16 of the guide stud 15 or guide prism 15 to be reduced or eliminated. In this case, it is possible for both of the slide strips 8 to be moved or for only one slide strip 8 to be moved.

[0081] Since this simultaneously causes the slide strips to come closer to each other or move farther away in the transverse direction, i.e. the direction 23, in this case, however, the oblong holes 10 had to be embodied so that they also enable a floating support in the direction 23 around the screws 20.

[0082] In order to adapt the slide strips 8 to the guide prism 15 and thus also to adapt the exact position of the slide body in the slide bed, it is possible, for example, to perform the adjustment from as stop position of the screws 20 in the oblong holes 10 (FIG. 5).

[0083] According to the invention, an adapter 40 is provided so that a corresponding adjustment of the guide play can be fixed in position from the outside (FIGS. 10, 11). The adapter 40 is positioned between an edge or surface 41 of the slide bed 2 situated axially in front of or behind the slide strip 8 and this edge or surface 41 is spaced apart from an end surface 42 of the slide strip 8. In order to secure the adapter 40 in its position, the adapter has a fixing element 43 that overhangs the edge or surface 41 oriented toward the slide bed 2, particularly in the vicinity of a step 44 provided for it, and is fixed in position there by means of a screw 45, which reaches through the adapter 40 and is then screwed into the material of the slide bed 2. The axial distance between the edge 41 and the edge 42 can thus be fixed so that the position of the screws 20 in the oblong holes 10 remains fixed. In order to fix different distances between the screws 20 and the oblong holes 10 depending on the adjustment position, the adapters can have different widths between the edges 41, 42.

[0084] This means that after the adjustment and fixing of the slide strip 8 by means of the screws 20, which are resting in the oblong holes 10, an appropriate adapter 40 is inserted in order to secure this adjustment.

[0085] In another advantageous embodiment of the invention (FIG. 12) the adapter is likewise situated between the edges 41, 42, but is arranged so that it is able to move between the edges 41, 42 to the extent that the overhanging region 43 and the shoulder 44 are spaced apart from each other in such a way that by screwing in the screw 55, the adapter 40, viewed from the outside, can be pushed deeper into the region between the edges 41, 42. In addition, the edge or surface 46 of the adapter 40 oriented toward the slide strips is provided with an inclined surface so that the adapter 40 is embodied as widening toward the outside. The edge 42 of the slide strip 8 is provided with a corresponding inclined surface in such a way that when the adapter 40 is pushed inward into the region between the edges 41, 42, this causes the slide strip 8 to move in the direction of the arrow 47. Preferably, the direction 47 is also the direction in which the guide play is reduced. By means of this, by screwing the screw 45 into the slide bed 2, the adapter 40 is screwed into the region between the edges 41, 42 and thus the slide strip 8 is correspondingly pushed in a direction toward less play. In this case, it is advantageous that the screwing in of the adapter from the outside, which is relatively easy to perform, permits the guide play to be easily moved or adjusted.

[0086] Naturally, it is also possible to embody an edge 48 of the adapter 40 oriented toward the slide bed with the corresponding inclined surface and thus to embody the edge 41 on the slide bed with a corresponding inclined surface, which functions in the same way as in the first embodiment.

[0087] Particularly with an inclined installation of the slide strips 8, the screws 45 are recessed from the outside and set back from the outer surface of the slide bed 2 to prevent damage and can nevertheless be easily reached, particularly with an offset screwdriver or tools of the like.

[0088] In another advantageous embodiment (FIG. 7 through 10), the adjustment takes place in a different way. In this embodiment, the surfaces 19 of the groove 5 and/or the slide bed 2 and/or the surface 22 that is oriented toward the wall 19 are embodied with an inclined surface. If both surfaces 19, 22 are embodied as inclined, then the inclined surfaces are embodied so that they are oriented in the same direction, i.e. the surfaces diverge or converge relative to each other and delimit a wedge-shaped intermediate space between themselves.

[0089] In order to adjust the distance between the slide surface 11 and a prism 15, which has slide surfaces 16 and is situated between the slide surfaces 11, in this embodiment, a corresponding wedge-shaped adapter is used, which depending on the design, either has an inclined surface 64 oriented toward the wall 22 or an inclined surface 65 oriented toward the wall 19 or has two inclined surfaces 64, 65 oriented toward the inclined walls 19, 22, This wedge consequently rests against these walls 19, 22 and extends between the slide strip 8 and the groove 5.

[0090] If this wedge 60 is moved into or out of the gap between the surfaces 19, 22 in accordance with a movement direction 61, then the slide strip 8 is consequently moved as a unit either in the direction toward a groove center 62 or away from it, respectively, in accordance with the directions 23.

[0091] In order to be able to move the wedge-shaped adapter or the wedge 60 into or out of the gap, the wedge 60 has an elbow 63, which is positioned on the wedge in such a way that the free end of the elbow is situated in the vicinity of the material of the slide and in this case in particular, that of the slide bed 2. The elbow region 63 has a screw 66 extending through it, which is supported in the elbow 63 in rotary fashion. By means of its screw head or by means of a corresponding device, this screw 66 acts on the elbow region 63 in such a way that screwing the screw 66 into the slide bed 2 (FIG. 8) moves the wedge into the gap between the surfaces 19, 22 and screwing it out moves the wedge 60 back out again.

[0092] In another embodiment, the screw 66 is not screwed into the slide, in particular into the slide bed 2, but rather directly into the slide plates 8, which produces the same result when it is screwed in and out.

[0093] In the invention, it is advantageous that the externally adjustable, movable slide strips achieve a simple, but very reliable and rugged adjusting possibility with good accessibility, even in very cramped installation situations; it is not necessary to remove the entire slide for the adjustment, but instead, it is sufficient to adjust the adapter using the corresponding screws provided for this purpose.

[0094] In the invention, it is advantageous that the adjustable slide strips and their L-shaped embodiment one the one hand and the prismatic guide prism 15 on the other achieve a very compact, but also very stable guidance of the slide body 3 in the slide bed 2 and in addition, extremely strict tolerances can be set in a simple way.
