DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] Next the technical schemes in the embodiments of the invention will be clearly and completely described with reference to the drawings in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of the invention.

[0039] In order to make the above-mentioned objects, features and advantages of the invention more obvious and easier to understand, the invention will be described in further detail below with reference to the drawings and detailed description.

Embodiment 1

[0040] As shown in FIG. 1-FIG. 6 and FIG. 19, the technological equipment for tank track moving support proposed in this invention includes the zero-point positioning system, the workpiece identifying system and the clamping apparatus cooperating with the moving support 3, the clamping apparatus includes the tooling plate 4, the clamp and the pressing device for pressing the moving support 3 are detachably connected to the tooling plate 4, and the moving support 3 is situated between the clamp and the pressing device, and the pressing device abuts against the moving support 3.

[0041] A set of manufacturing cell consists of two machining centers 1, each of which is equipped with two workbenches 2 respectively. The workbenches 2 assists the manipulator to replace the moving support 3 in the machining centers 1. Machining centers 1 are equipped with zero-point positioning system and workpiece identifying system. The zero-point positioning system completes zero-point positioning through DLDDW-138 zero-point positioning module. The application of the zero-point positioning system is beneficial to the industrial camera to lock the identifying area and facilitates the machine tool processing and programming. The workpiece identifying system refers to a common identifying system in the prior art. The tooling plate 4 is the key to linking the moving support 3 with the machining centers 1. After the workpiece is processed, the tooling plate 4 can be detached from the follow fixture and reused in other fixtures.

[0042] In a further optimization scheme, when the side surface of the moving support 3 opposite to the surface to be processed of the moving support is uneven, the surface to be processed of the moving support 3 is flat, and the side surface opposite to the surface to be processed is fixedly provided with a cylindrical protrusion, so clamping can be only achieved on the side surface. At this time, the clamp specifically includes the supporting block 5, which is provided with the special-shaped groove 7, and the special-shaped groove 7 includes two trapezoidal grooves which are communicated with each other and have different sizes; the moving support 3 is located in the special-shaped groove 7 and abuts against the trapezoidal groove with the smaller size, while the cylindrical protrusion on the moving support 3 is in the trapezoidal groove with the larger size; the pressing device includes the pressing arm 8 and the pressing part, the pressing arm 8 is fixedly connected with the clamp and the pressing part is arranged on the pressing arm 8 and abuts against the moving support 3; the moving support 3 is limited by the special-shaped groove 7, the third positioning pin is fixedly connected to the supporting block 5, and the moving support 3 is positioned by the third positioning pin, so it is easy to press the moving support 3 tight by the pressing device. When positioning the workpiece is carried out, the moving support 3 is placed on the special-shaped groove 7 of the clamps. According to the six-point positioning principle, the special-shaped groove 7 restrains the moving support 3 from moving in the Z-axis direction, the movement in the X-axis direction, the rotation around the X-axis direction and the rotation around the Z-axis direction. The third positioning pin is in contact with the moving support 3 to restrict the rotation and movement of the moving support 3 around the Y-axis direction; the moving support 3 is clamped in the machining center 1, and then the surface to be processed of the moving support 3 are subject to machining processes, such as milling, contour milling, annular milling, boring, drilling, tapping and thread milling.

[0043] In a further optimization scheme, the four corners of the supporting block 5 are provided with threaded holes, which are fixedly connected with the tooling plate 4 through bolts. Adding threaded holes is carried out at the sideline position of the supporting block 5 depending on the size of the supporting block 5, to ensure the fixed strength between the supporting block 5 and the tooling plate 4.

[0044] In a further optimization scheme, the side wall to be processed of the moving support 3 abuts against the side wall of the supporting block 5. The size of the side wall to be processed is larger than that of the supporting block 3, so that when the moving support 3 is in the special-shaped groove 7, the side wall to be processed is out of the special-shaped groove 7. Since the side wall to be processed abuts against the side wall of the supporting block 5, the moving support 3 will not slide inward along the special-shaped groove 7 during processing the surface to be processed, so that the moving support 3 can be processed normally.

[0045] In a further optimization scheme, the pressing part includes the first pressing part 10, the second pressing part 11 and the square column 12, one end of the pressing arm 8 facing away from the supporting block 5 is provided with two pressing protrusions 13 arranged in parallel up and down as an upper pressing protrusion and a lower pressing protrusion respectively, the upper pressing protrusion 13 is screwed with pressing bolts 14, the square column 12 slides through the lower pressing protrusion 13, both ends of the square column 12 are fixedly connected with the first pressing part 10 and the second pressing part 11 respectively, and the second pressing part 11 is located between the two pressing protrusions 13; the first pressing part 10 adopts a plate-like structure, the square column 12 applies pressure to the moving support 3 through the first pressing part 10, the second pressing part 12 has a cylindrical structure, and the pressing bolt 14 applies pressure to the second pressing part 12, so that the first pressing part 10 applies pressure to the moving support 3; the return spring 15 is fixedly connected between the second pressing part 11 and the lower pressing protrusion 13, the return spring 15 is sleeved outside the square column 12, and the first pressing part 10 abuts against the moving support 3. The square column 12 can prevent the first pressing part 10 from rattling and scratching the workpiece. When the pressing part presses down the moving bracket 3, the pressing bolt 14 is tightened, and the threaded structure makes the moving support go down, thereby driving the first pressing part 10 and the second pressing part 11 to press down. Therefore, the bottom of the first pressing part 10 contacts with the moving support 3 and moving support 3 is pressed tight. After the machining is finished, the pressing bolt 14 is loosened and moved upwards, and the first pressing part 10 and the second pressing part 11 are reset under the action of the return spring 15, so that the moving support 3 is free from clamping, and the machined moving support 3 is taken out.

Embodiment 2

[0046] Referring to FIG. 7-FIG. 13, this embodiment proposes the technological equipment for tank track moving supports. The only difference between this embodiment and the embodiment 1 is that when the surface to be processed of the moving support 3 is uneven, one side of the end face of the moving support 3 is fixedly provided with the convex inclined plane 16, the other side of the end face of the moving support 3 is provided with the concave inclined plane 17, the convex inclined plane 16 is correspondingly provided with the concave inclined plane 17 and the inclination angle of the convex inclined plane 16 is opposite to that of the concave inclined plane 17; the clamp includes a plurality of first positioning blocks 18, and the moving support 3 is positioned above the first positioning blocks 18; the bottom of the first positioning blocks 18 is detachably connected with the tooling plate 14, and the first positioning block 18 is screwed with the first positioning/supporting pin 19; the first positioning pin 19 abuts against the moving support 3, and the pressing device includes the third pressing part 6 and the fourth pressing part 36, the third pressing part 6 and the fourth pressing part 36 are located at both sides of the moving support 3. The first positioning block 18 adopts a strip-shaped flat plate structure, the first positioning block 18 is provided with countersunk holes in the axial direction, the first positioning block 18 is fixedly connected with the tooling plate 4 through the countersunk holes, the end of the first positioning block 18 is provided with a threaded hole, the first positioning block 18 is fixedly connected with the first positioning pin 19 through the threaded hole and the first positioning pin 19 contacts with the moving support 3 to position the moving support 3.

[0047] In a further optimization scheme, the third pressing part 6 includes the first cylinder 20 and the first pressing plate 21, the extension rod of the first cylinder 20 is fixedly connected with the first pressing plate 21, and the first pressing plate 21 abuts against the convex inclined plane 16 of the moving support 3. The total pressure acting by the third pressing part 6 on the moving support 3 is F.sub.1, and the included angle in other numerical directions is α, and then the positive pressure F.sub.α of the third pressing part 6 on the moving support 3 is F.sub.α=F.sub.1 cos α.

[0048] In a further optimization scheme, the fourth pressing part 36 includes the first base 22, which is detachably connected with the tooling plate 4, one end of the first base 22 close to the third pressing part 6 is fixedly connected with the second cylinder 23, the extension rod of the second cylinder 23 is fixedly connected with the sliding chuck 24, the sliding chuck 24 is hinged with the first connecting rod 25, the first connecting rod 25 is fixedly connected with the second pressing plate 26, the second pressing plate 26 abuts against the concave inclined plane 17. The output thrust of the second cylinder 23 is F.sub.2, when pressing, the included angle between the first connecting rod 25 and the vertical direction is θ, and then the vertical component is F.sub.2 cot θ. According to the lever principle, taking the equidistant sides of the first connecting rod 25 as an example, then the pressing force of the fourth pressing part 36 on the moving support 3 is F.sub.θ, wherein F.sub.θ=F.sub.2 cot θ, therefore the pressing force of the pressing device on the moving support 3 is F.sub.N=F.sub.1 cos α+F.sub.2 cot θ.

[0049] In the process of pressing, the first cylinder 20 drives the first pressing plate 21 to move directly, the first pressing plate 21 contacts with the convex inclined plane 16 and exerts clamping force to tighten one side of the moving support 3, and the second cylinder 23 drives the sliding chuck 24 to make the first connecting rod 25 rotate, driving the second pressing plate 26 to press the concave inclined plane 17 and exert clamping force to tighten the other side of the moving support 3. In this case, the first pressing plate 21 and the second pressing plate 26 work together to not only limit the horizontal movement of the moving support 3, but also press the moving support 3 against the clamps, so that the clamping reliability is high.

Embodiment 3

[0050] Referring to FIG. 14-FIG. 18, this embodiment provides the technological equipment for tank track moving supports. The only difference between this embodiment and the embodiment 1 is that when the moving support 3 includes the square structure which is convenient for clamping, the moving support 3 includes the square clamping part 27 and an object to be processed, each pressing device is arranged between two moving supports 3 and abuts against the two moving supports 3, and each clamp is located below the two moving supports 3. When mass production is required, multiple groups of pressing devices can be installed in parallel on the tooling plate 4, and multiple moving supports 3 can be clamped and processed together, which shortens the time for changing tooling and improves the working efficiency.

The second positioning block 29 and the second positioning pin 31 on the second positioning block 29 simultaneously tighten the two groups of workpieces, and the moving support 3 is clamped several times to realize the processing procedures, such as face milling, contour milling, drilling, tapping and thread milling. During the clamping process, the thickness of the mounting plate 28 can be adjusted to adjust the relative height between the moving support 3 and the slider 34, and the clamping part 27 of the moving support 3 can be pressed by the pressing device.

Under the action of the second connecting rods 38, the sliders 34 on both sides move horizontally along the guide rails 35, clamping the moving supports 3 on both sides simultaneously. When the pressing device presses the moving supports 3, the included angle between the second connecting rod 38 and the vertical direction is β, and the reaction force of the second connecting rods 38 on both sides forms a mechanical balance with the thrust F.sub.3 of the cylinder extension rod, and the thrust F′ of the second connecting rods 38 is horizontally separated into clamping force F.sub.β, then
