[0003] Current tooling for machining disc-shaped parts has at least two fastening pins threaded onto its base. Each fastening pin has a clamping plate welded to its end. By turning the two fastening pins, the clamping plates clamp the workpiece. However, the turning distance of the two fastening pins needs to be precisely controlled to ensure that the workpiece is positioned on the central axis of the tooling. However, the turning distance of the fastening pins is not easy to control, resulting in inaccurate positioning. Therefore, it is often necessary to tighten and fix the workpiece repeatedly, resulting in low workpiece positioning and clamping efficiency. Utility Model Content

By turning the two fastening pins, the two clamping plates clamp the workpiece tightly. However, it is necessary to precisely control the turning distance of the two fastening pins to ensure that the workpiece is located at the central axis of the tooling. However, the turning distance of the fastening pins is not easy to control, resulting in inaccurate positioning. Therefore, it is often necessary to repeatedly tighten and fix the workpiece, resulting in low positioning and clamping efficiency.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A self-positioning tooling for machining disc-shaped parts includes a tooling base, on which a clamping mechanism is mounted. The clamping mechanism has two clamping plates that are symmetrical about the central axis of the tooling base.

[0015] Compared with existing technologies:

[0016] 1. By setting up a clamping mechanism with two clamping plates symmetrical about the central axis of the tooling base, the two clamping plates move in opposite directions at the same speed under the action of the clamping mechanism, thereby automatically clamping the workpiece at the central axis of the tooling base, realizing tool self-positioning and clamping, and thus improving the workpiece processing efficiency.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Example 1:

[0025] This utility model provides a machining fixture for disc-shaped parts with self-positioning function. Please refer to [link / reference]. Figure 1-2 The fixture includes a tooling base 1, on which a clamping mechanism is installed. The clamping mechanism has two clamping plates 3, which are symmetrical about the central axis of the tooling base 1. Under the action of the clamping mechanism, the two clamping plates 3 move in opposite directions at the same speed.

[0026] The clamping mechanism includes a slider 7 slidably connected to the tooling base 1. Specifically, the tooling base 1 has a groove 6, and the slider 7 is slidably connected to the inner wall of the groove 6. A support rod 5 is welded to the slider 7, and the end of the support rod 5 is connected to the clamping plate 3. Specifically, a first support connecting seat 4 is welded to the outer wall of the clamping plate 3, and the support rod 5 is inserted into the inner wall of the first support connecting seat 4. The support rod 5 and the first support connecting seat 4 are fixed together by bolts. An obtuse angle plate 8 is movably connected to the slider 7. Specifically, a first fixing pin 9 is welded to the slider 7, and a first wedge-shaped through hole 81 is opened at the top of the obtuse angle plate 8. The first fixing pin 9 passes through the first wedge-shaped through hole 81. The obtuse angle plate 8 is rotatably connected to a vertical pin 10 through a bearing. The vertical pin 10 is welded to the tooling base 1. The other end of the obtuse-angle plate 8 is movably connected to a traction plate 12. Specifically, a second fixing pin 11 is welded to the traction plate 12, and a second wedge-shaped through hole 82 is opened at the bottom end of the obtuse-angle plate 8. The second fixing pin 11 passes through the second wedge-shaped through hole 82. An electric push rod 14 is installed between the traction plate 12 and the tooling base 1. Specifically, a second support connecting seat 13 is welded to the traction plate 12, and the electric push rod 14 is inserted into the inner wall of the second support connecting seat 13. The electric push rod 14 and the second support connecting seat 13 are fixed together by bolts. A support block 16 is welded to the tooling base 1, and a second support connecting seat 15 is welded to the support block 16. The electric push rod 14 is inserted into the inner wall of the second support connecting seat 15, and the electric push rod 14 and the second support connecting seat 15 are fixed together by bolts.

[0027] In practical use, the workpiece 2 is placed between the two clamping plates 3. The electric push rod 14 retracts and drives the traction plate 12 to descend. The traction plate 12 drives the two obtuse angle plates 8 to rotate. The two obtuse angle plates 8 drive the two sliders 7 to move closer to each other, thereby driving the two clamping plates 3 to clamp the workpiece 2 tightly. Since the two clamping plates 3 move in opposite directions at the same speed, the two clamping plates 3 clamp the workpiece on the central axis of the tooling base 1.

[0028] Example 2:

[0029] See attached document Figure 3-4 Unlike Embodiment 1, the present invention also includes a pre-positioning mechanism. The pre-positioning mechanism includes a support plate 17 welded to the tooling base 1. A pull rod 21 is slidably connected to the support plate 17. A pre-clamping plate 18 is welded to one end of the pull rod 21. A spring 19 is sleeved on the pull rod 21. The two ends of the spring 19 are respectively fixedly connected to the pre-clamping plate 18 and the support plate 17. Specifically, one end of the spring 19 is welded to the support plate 17, and the other end of the spring 19 is welded to a mounting plate 20. The mounting plate 20 is fixed to the pre-clamping plate 18 by bolts.

[0030] In practical use, one of the pull rods 21 is pulled outward to drive the corresponding pre-clamping plate 18 to move, and the workpiece 2 is placed between the two pre-clamping plates 18. The elastic force of the two springs 19 is the same, so the workpiece is clamped between the two clamping plates 3. The electric push rod 14 retracts and drives the traction plate 12 to descend. The traction plate 12 drives the two obtuse angle plates 8 to rotate. The two obtuse angle plates 8 drive the two sliders 7 to move closer to each other, thereby driving the two clamping plates 3 to clamp the workpiece 2 tightly. Since the two clamping plates 3 move in opposite directions at the same speed, the two clamping plates 3 clamp the workpiece on the central axis of the tooling base 1.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
