DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a tooling fixture, the tooling fixture includes: a processing plate 1, a chute 4 is provided on the surface of the processing plate 1, an electric push rod 2 is arranged in the chute 4, and a support plate 3 is arranged at the lifting end of the electric push rod 2;

[0025] A positioning plate 5, a moving groove 6 is provided on the side surface of the positioning plate 5, a bearing 7 is arranged at the end face of the moving groove 6, a moving screw 8 is arranged in the bearing 7, and an auxiliary plate 9 is screwed on the surface of the moving screw 8. A precision molding grinder production device includes the above-mentioned tooling fixture;

[0026] During use, the support plate 3 can be pushed by two groups of electric push rods 2, so that the positioning plate 5 can clamp and position the workpiece. Then, the moving screw 8 can be rotated in cooperation with the bearing 7 to displace the auxiliary plate 9, so that the side surface of the positioned workpiece can be limited by the auxiliary plate 9, thus avoiding the problem of workpiece offset when the workpiece is processed by the grinder and improving the stability of the processed workpiece after positioning.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, a positioning plate 5 is provided to facilitate positioning and clamping of the workpiece. There are two groups of chutes 4, and the two groups of chutes 4 are symmetrically distributed about the center line of the long side of the side surface of the processing plate 1. A positioning frame 10 is arranged in the chute 4, the electric push rod 2 is fixedly connected in the positioning frame 10, the support plate 3 is integrally in an "L"-shaped plate structure, the support plate 3 is fixedly connected to the lifting end of the electric push rod 2, and the positioning plate 5 is fixedly connected to the end face of the support plate 3;

[0029] During use, first, the electric push rod 2 can be started to push the support plate 3 to displace, so that the two groups of positioning plates 5 can position and clamp the workpiece, thus facilitating the grinder to process the workpiece.

[0030] In order to further improve the stability of the workpiece after clamping, an auxiliary plate 9 is provided. The bearing 7 is fixedly connected to the end face of the moving groove 6, a traction rod 16 is arranged at the end face of the moving groove 6, one end of the auxiliary plate 9 is sleeved on the traction rod 16, and the auxiliary plate 9 can slide along the traction rod 16;

[0031] When in use, after the workpiece is clamped by the positioning plate 5, the auxiliary plate 9 can be displaced by rotating the moving screw 8 in cooperation with the bearing 7, so as to position both sides of the positioned workpiece. The setting of the traction rod 16 can avoid the problem that the auxiliary plate 9 also rotates when the moving screw 8 is rotated.

[0032] Embodiment III

[0033] On the basis of Embodiment II, in order to improve the stability of workpiece clamping, a limiting plate 12 is provided. A moving opening 11 is formed on the side surface of the positioning plate 5. There are two groups of moving openings 11, and the two groups of moving openings 11 are symmetrically distributed about the center line of the long side of the side surface of the positioning plate 5. A limiting plate 12 is arranged in the moving opening 11. The limiting plate 12 can slide in the moving opening 11. A support rod 13 is arranged at the end face of the limiting plate 12. A fixing frame 14 is arranged on the side surface of the positioning plate 5. A hole is formed on the side surface of the fixing frame 14. One end of the support rod 13 is inserted into the fixing frame 14. A limiting spring 15 is sleeved on the surface of the support rod 13. One end of the limiting spring 15 is fixedly connected to the inner side surface of the fixing frame 14, and the other end of the limiting spring 15 is fixedly connected to the end face of the limiting plate 12.

[0034] When in use, when clamping with the positioning plate 5, the setting of the limiting plate 12 can be used to support the bottom of the workpiece, and it is also convenient for the two positioning plates 5 to clamp the workpiece. When clamping a workpiece that does not require bottom support, the limiting plate 12 can be pressed to extend into the moving opening 11 for storage. The setting of the limiting spring 15 can prevent the limiting plate 12 from randomly displacing along the moving opening 11 and improve the stability of the limiting plate 12.

[0035] During actual use, the two electric push rods 2 can be used to push the support plate 3, so that the positioning plate 5 can clamp and position the workpiece. Then, the auxiliary plate 9 can be displaced by rotating the moving screw 8 in cooperation with the bearing 7, so that the side surface of the positioned workpiece can be limited by the auxiliary plate 9. Thus, when the workpiece is processed by a grinding machine, the problem of workpiece offset can be avoided, and the stability of the processed workpiece after positioning can be improved. In this way, it is avoided that the traditional positioning fixture mainly clamps and positions the workpiece through two positioning plates 5, but generally the positioning fixture is mainly a plane. When the workpiece is clamped by two positioning fixtures, it may cause the problem that the workpiece is offset when the grinding machine processes the workpiece.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
