[0021] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.
[0022] Embodiment
[0023] Reference Figure 1 And Figure 3 The present embodiment provides a cap lock assembly clamp, which is especially suitable for a countersunk cap lock. The assembly clamp comprises a vice base 1, the vice base 1 is provided with a pressing block 2, the upper end of the pressing block 2 is provided with a first groove 201 matched with a screw 501 of the cap lock 5. When assembling the pin on the cap lock 5, the cap lock 5 is placed on the pressing block 2, and the screw 501 of the cap lock 5 is located in the first groove 201. Through the cooperation of the screw 501 and the first groove 201, the cap lock 5 is limited. Finally, the pins are knocked into the aligned positions one by one, so that the assembly of the pins on the cap lock 5 is realized.
[0024] Reference Figures 1 to 3 Since the striking force is relatively large during the assembly of the pin of the cap lock 5, in order to further ensure the stability of the cap lock during the assembly process, the first limiting piece 3 and the second limiting piece 4 are further arranged on the vice base 1 in the present embodiment. The pressing block 2 is located between the first limiting piece 3 and the second limiting piece 4. When the pin on the cap lock 5 is assembled, the cap lock 5 is matched with the pressing block 2, and the two sides of the cap lock are clamped by the first limiting piece 3 and the second limiting piece 4.
[0025] Specifically, the first limiting piece 3 is a first protruding part fixedly arranged on the upper end of the vice base 1. The second limiting piece 4 comprises a lead screw 401 and a second protruding part 402 fixedly arranged on the upper end of the vice base 1. The lead screw 401 passes through the second protruding part 402. The screw end of the lead screw 401 is located between the second protruding part 402 and the pressing block 2, and the end of the lead screw 401 is fixedly connected with a moving seat 403. The moving seat 403 is slidingly connected with the vice base 1. The distance between the first protruding part and the pressing block 2 is determined according to design requirements. After the cap lock is placed on the pressing block 2, the side of the cap lock 5 close to the first protruding part abuts against the first protruding part. After the cap lock 5 is placed on the pressing block 2, the lead screw 401 is adjusted, so that the moving seat 403 and the first protruding part clamp the two sides of the cap lock 5, thereby realizing the stability during the assembly process. Preferably, after the cap lock 5 is placed on the pressing block 2, the height of the moving seat 403 and the height of the first protruding part are both higher than the height of the tooth disc 502 of the cap lock 5, so that the moving seat 403 and the first protruding part can clamp the two sides of the tooth disc 502.
[0026] In order to adapt to different specifications of the cap lock 5, the lower end of the pressing block 2 is slidably connected with the vice base 1, specifically, the upper end of the vice base 1 is provided with a third protruding part 101, the third protruding part 101 is located between the first protruding part and the second protruding part 402, the lower end of the pressing block 2 is provided with a second groove 202 matched with the third protruding part 101, the pressing block 2 can slide along the third protruding part 101 after matched with the third protruding part 101, since the screw 501 of different specifications of the cap lock 5 is the same, the difference lies in the size of the tooth disc 502, in order to clamp the tooth disc 502 of the cap lock 5 by the first limiting part 3 and the second limiting part 4, the distance between the first protruding part and the pressing block 2 can be adjusted by sliding the pressing block 2 on the third protruding part 101, the distance between the moving seat 403 and the pressing block 2 is adjusted by the adjusting screw 401, so that the stability of the cap lock 5 of different specifications in the assembling process is ensured.
[0027] In the embodiment, the third groove 102 is arranged at the lower end of the vice base 1 while the stability of the vice base 1 is ensured, and the material is saved.
