[0002] Mechanical parts, also known as mechanical elements, are single, inseparable parts that make up machinery and machines. They are the basic units of machinery. Mechanical parts processing refers to the process of changing the size or performance of a workpiece through a mechanical device. During mechanical processing, different surfaces of the workpiece need to be processed, which requires a fixture to clamp it. A fixture usually refers to a device used to fix and clamp products in a mass production process to facilitate the processing of clamped products.

[0026] A machining jig for mechanical parts comprises a machining jig box 1, an electric cylinder 2 is fixedly installed on the left side of the inner wall of the machining jig box 1, a push plate 3 is fixedly connected to the output end of the electric cylinder 2, a sliding assembly is connected to the bottom of the push plate 3, a drive motor 4 is fixedly installed on the side of the push plate 3, a mobile clamping frame 5 is fixedly connected to the output end of the drive motor 4, a fixed clamping frame 6 is fixedly connected to the right side of the inner wall of the machining jig box 1, an electric cylinder 2 7 is fixedly installed on the bottom of the inner wall of the machining jig box 1, a lower support plate 8 is fixedly connected to the output end of the electric cylinder 2 7, a stabilizing plate 9 is fixedly connected to the front and rear sides of the inner wall of the machining jig box 1 through grooves, a shock absorber 10 is fixedly connected to the surface of the stabilizing plate 9, one end of the shock absorber 10 is fixedly connected to an anti-collision guard plate 11 with a collision sensor, a pressure-absorbing elastic pad 12 is fixedly connected between the surface of the anti-collision guard plate 11 and the surface of the stabilizing plate 9, and a raised wear-resistant pad 13 is fixedly connected to the surface of the anti-collision guard plate 11.

[0027] Specifically, Figure 1-Figure 5 As shown, a shock absorbing platform 14 is fixedly connected to the bottom of the processing jig box 1, and the lower surface of the shock absorbing platform 14 is provided with an anti-slip surface. Under the action of the shock absorbing platform 14, the anti-seismic force unloading effect is ensured when the mechanical parts are processed inside the processing jig box 1.

[0028] Furthermore, an anti-skid sleeve 15 is fixedly connected to the side of the processing jig box 1, and a dust-proof cover plate 16 is clamped on the inner wall of the anti-skid sleeve 15. The dust-proof cover plate 16 above the processing jig box 1 is removed from the anti-skid sleeve 15 to expose the internal environment of the processing jig box 1 for clamping mechanical parts, and under normal circumstances, the dust-proof cover plate 16 can be covered and connected thereon for dust protection.

[0029] Specifically, Figure 1-Figure 5 As shown, the main body of the movable clamping frame 5 and the main body of the fixed clamping frame 6 are both U-shaped frames, and the front and rear sides of the U-shaped frames are fixedly installed with electric cylinder three 20, and the output end of the electric cylinder three 20 is fixedly connected with an anti-slip clamping plate 21. The operation of the electric cylinder three 20 can drive the anti-slip clamping plate 21 to move, and the two anti-slip clamping plates 21 close to each other can clamp the mechanical parts in the middle.

[0030] Example 2 Please refer to Figure 1-Figure 5 The difference between this embodiment and the embodiment 1 is that the sliding assembly includes an anti-tilt slide plate 17 and an anti-tilt slide groove 18, the anti-tilt slide plate 17 is fixedly connected to the bottom of the push plate 3, the anti-tilt slide groove 18 is provided on the lower surface of the inner wall of the processing jig box 1, and the inner wall of the anti-tilt slide groove 18 is slidably connected to the surface of the anti-tilt slide plate 17. A wear-resistant stretch sleeve 19 is fixedly connected to the top of the anti-tilt slide groove 18 near its inner wall, and the surface of the wear-resistant stretch sleeve 19 is fixedly connected to the surface of the anti-tilt slide plate 17.

[0031] Working principle of the utility model: during use, when it is necessary to perform processing operations on mechanical parts, the dustproof cover plate 16 above the processing jig box 1 can be removed from the anti-slip clamping sleeve 15 to expose the internal environment of the processing jig box 1 to clamp the mechanical parts, and under normal circumstances, the dustproof cover plate 16 can be covered and connected thereon for dust protection. First, the mechanical parts are placed above the lower support plate 8, and then the electric cylinder 2 7 is started to drive the lower support plate 8 to adjust the height, so that the subsequent electric cylinder 1 2 can drive the moving clamp 5 to approach the fixed clamp 6. Under the action of the anti-tilt slide plate 17 and the anti-tilt slide groove 18, the deflection of the push plate 3 during movement is reduced, and a wear-resistant stretch sleeve 19 is added for protection to prevent debris from falling into the anti-tilt slide groove 18, so as to avoid the situation where the subsequent push plate 3 is blocked. The middle mechanical parts are abutted and clamped at the left and right positions, and the operation of the electric cylinder 3 20 can drive the anti-skid clamping plate 21 to move. The two anti-skid clamping plates 21 close to each other can clamp the middle mechanical parts, and can complete the left, right, front, back and bottom position constraint clamping of the mechanical parts inside the processing fixture box 1. If the mechanical parts slip during the processing, the mechanical parts will fall and collide with the anti-collision guard plate 11. The collision sensor inside the anti-collision guard plate 11 can sense and notify the surrounding staff after the collision. The raised wear-resistant pad 13 on the anti-collision guard plate 11 can play a wear-resistant and force-unloading effect. At the same time, the shock absorber 10 and the pressure-reducing elastic pad 12 at the rear side of the anti-skid guard plate can play a secondary shock-absorbing and force-unloading effect, which can ensure the multi-directional constraint of the mechanical parts and the anti-collision sensing and force-unloading effect after slipping.
