Tool holde panel mounting structure for spring making machine

Abstract

A tool holder configuration structure for spring making machine includes a flat base plate and three displacement mechanisms arranged on the front side in a triangle, each displacement mechanism including a first sliding tract set and a second sliding tract set arranged at right angles, and three tool holder panels each said tool holder panel including a base, a first tool holder located on one side of the base and two second tool holders obliquely disposed at two opposite lateral sides of the first tool holder. The tool holder panels are respectively coupled to the second sliding tract sets of the displacement mechanisms to keep the first tool holders adjacent to one another so that the moving distance of the tool holder panels can be minimized and a large number of tools can be installed in each tool holder panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(7) Referring to FIGS. 1 and 2, a tool holder configuration structure in accordance with the present invention is shown used in a spring making machine that comprises a machine body 10 having mounted thereon a wire guide 101 and a rotator 102. The rotator 102 comprises a servo motor 1021, and a transmission belt 1022 coupled between the servo motor 1021 and the wire guide 101 and driven by the servo motor 1021 to rotate the wire guide 101 within a predetermined angle. The machine body 10 further comprises a power system, a central processing unit, a control system, power drive means, transmission means, etc. As the machine body 10 is not in the scope of the present invention, no further detailed description in this regard will be necessary.

(8) Referring to FIGS. 3 and 4, the tool holder configuration structure comprises a flat base plate 1 and three tool holder panels 2.

(9) The flat base plate 1 comprises three displacement mechanisms (11,12) arranged on a front side thereof in a triangle with two displacement mechanisms 11 arranged at two opposite lateral sides to face each other and the other displacement mechanism 12 arranged at a top side and equally spaced from the two lateral displacement mechanisms 11. The displacement mechanism (11,12) each comprise a first sliding tract set (111,121), and a second sliding tract set (112,122) connected to the first sliding tract set (111,121). The first sliding tract set (111,121) comprises a first rail track (1111,1211), a displacement board (1112,1212) slidably mounted on the first rail track (1111,1211), and a first driver (1113,1213) disposed at one side relative to the first rail track (1111,1211) and coupled with the displacement board (1112,1212) and controllable to move the displacement board (1112,1212) alternatively forward and backward along the first rail track (1111,1211). The second sliding tract set (112,122) comprises a second rail track (1121,1221) mounted on the displacement board (1112,1212) in a direction perpendicular to the extending direction of the first rail track (1111,1211), and a second driver (1122,1222) disposed at one side relative to the second rail track (1121,1221).

(10) Each tool holder panel 2 comprises a base 21, a first tool holder 22 located on one side of the base 21, and two second tool holders 23 located on the base 21 at two opposite lateral sides of the first tool holder 22 in an oblique manner and respectively defining with the first tool holder 22 a contained angle of 135 degrees. The first tool holder 22 comprises a plurality of first positioning grooves 221, and a plurality of first positioning holes 222 disposed in each first positioning groove 221. Each second tool holder 2 comprises a plurality of second positioning grooves 231, and a plurality of second positioning holes 232 disposed in each second positioning groove 231. Further, these three tool holder panels 2 are respectively coupled to the second rail tracks (1121,1221) of the aforesaid three displacement mechanisms (11,12). Since the first tool holders 22 of the three tool holder panels 2 are disposed in a triangle and the second tool holders 23 of each tool holder panel 2 respectively define with the associated first tool holder 22 a contained angle of 135 degrees, the adjacent second tool holders 23 of each two adjacent tool holder panels 2 are kept in parallel. Further, the opposite side of the base 21 of each tool holder panel 2 remote from the associated first tool holder 22 is connected to the second driver (1122,1222) of the second sliding tract set (112,122) of one respective displacement mechanism (11,12) so that the respective second drivers (1122,1222) can be controlled to move the respective tool holder panels 2 alternatively forward and backward along the respective second rail tracks (1121,1221). Thus, the first tool holders 22 of the tool holder panels 2 can be moved close to or away from one another.

(11) Referring to FIGS. 3-6 and more particularly to FIG. 5, since the second tool holders 23 of the tool holder panels 2 are respectively disposed in an oblique manner relative to the respective first tool holders 22, the first tool holders 22 and the second tool holders 23 allow installation of a large amount of tools 3 at different angles within the limited surface space of the respective tool holder panels 2. Further, when tools 3 are mounted in the first positioning holes 222 of the first tool holders 22, the loaded tools 3 face toward a first direction. Further, the first positioning grooves 221 face toward a second direction different from the first direction. Further, as illustrated in FIG. 6, the tools 3 each have a variety of different functions including guiding, positioning, rotating, bending and cutting, and are movable by the respective tool holder panels 2. Further, the tool holder panels 2 are movable by the respective displacement mechanisms (11,12). Thus, the loaded tools 3 can be moved subject to the control of a predetermined software program to process a metal wire into the desired springs 4. Since the tool holder configuration structure of the present invention provides three displacement mechanisms (11,12) and three tool holder panels 2. Thus, when one tool holder panel 2 completed the processing operation, the tool holder panels 2 are moved at the same time, feeding one tool 3 into the processing position and simultaneously retracting another tool 3 away from the processing position, and thus, the tool feeding and retracting operation can be greatly accelerated. Further, because the second tool holder 23 one tool holder panel 2 is disposed in parallel to one adjacent second tool holder 23 of another adjacent tool holder panel 2, each two adjacent tool holder panels 2 are disposed close to each other, and the traveling distance of the minimizing the tool holder panels 2 can be significantly reduced.
