[0017] The present invention will be further described below with reference to the embodiments given in the accompanying drawings; Reference Figures 1 to 5As shown, a solid retainer locking point processing device of the present embodiment comprises a base 1, a punch rod 6 and a lock base 2, wherein the lock base 2 is mounted on the base 1, the punch rod 6 is movably arranged on the base 1 and is located above the lock base 2, the solid retainer is mounted on the lock base 2, the lock base 2 comprises a base plate 21 and a base block 22, the base 1 is an L-shaped plate structure, one end of the base plate 21 is rotatably mounted on the vertical plate surface of the base 1, the base block 22 is fixed on one end of the base plate 21 facing away from the vertical plate surface of the base 1, the solid retainer is mounted on the base block 22 so as to rotate with the rotation of the base plate 21, and in the process of using the solid retainer locking point processing device, it is only necessary to mount the solid retainer to the lock The punch rod 6 is then driven down through the external pressure component to realize the locking point processing of the physical retainer. In the process of installing the physical retainer on the locking base 2, the physical retainer is installed on the base block 22, and then the base plate 21 is used to position the angle so that the pocket hole pressing locking point is at a 90-degree position. The punch rod 6 is pressed down vertically to adjust the locking mouth pressing depth to obtain a suitable locking amount, thereby realizing the processing of one locking point. Then the retainer is driven to rotate and the other pocket hole pressing locking point is adjusted to a 90-degree position. Then the above process is repeated to complete the processing of the other pocket hole pressing locking point. Compared with the method of only being able to fix the angle in the prior art, this can achieve fine-tuning of the pocket hole angle during processing, effectively improving the qualified rate of the locking point processing.

[0018] As a specific implementation of the improvement, the base block 22 is a one-third circular disk structure, which is coaxially arranged with the base plate 21, and the arc surface of the one-third circular disk is provided with a fixing mechanism for fixing the solid retaining frame. Through the arrangement of the above structure, on the one hand, the bearing capacity of the locking point processing position of the solid retaining frame can be maximized, and on the other hand, the problem of difficulty in disassembly and assembly due to the adaptation of the diameter of the base block 22 to the solid retaining frame will not be avoided.

[0019] As an improved specific implementation method, the fixing mechanism includes a positioning block 3, a positioning hole 4 is opened on the arc surface of the one-third circular disk, and a positioning column is fixed on the positioning block 3.

The punch rod 6 can be lifted and lowered through the lifting sleeve 53 and is connected to the lifting sleeve 53 through a flat key. Through the setting of the above structure, the rotation of the punch rod 6 can be limited by the flat key, so that the punch rod 6 can perform the stamping work better.

[0023] As an improved specific implementation, a limiting long groove 61 is provided on the side wall of the punch rod 6, and the limiting long groove 61 extends along the length direction of the punch rod 6. The end of the cross bar 5 is threadedly connected with a limiting bolt, and the limiting bolt passes through the end of the cross bar 5 and the lifting sleeve 53 and then extends into the limiting long groove 61. By setting the limiting long groove 61, the up and down lifting of the punch rod 6 can be further limited effectively, thereby avoiding a series of problems caused by excessive stroke of the punch rod 6.

[0024] As an improved specific implementation, a pressure-bearing part is coaxially fixed to the upper end of the punch rod 6, and a wedge-shaped groove is provided on the circumferential edge of the upper end face of the pressure-bearing part so that the pressure-bearing part has a structure of a combination of a cone and a cylinder.
