Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a positioning device for pin assembly of a lock. Background Technique

[0002] The lock pin is an important part inside the lock, especially in a pin tumbler lock. When discussing locks, "pins" usually refer to the tumblers or balls inside the lock, which are used to prevent the lock core from rotating unless the correct key is used to align these pins.

[0003] When assembling the pins of the lock, it is necessary to fix and adjust the pins on the lock core in place, so that it is convenient for the subsequent operators to install the pins inside the pin installation position. When the existing lock is installed, if the lock is displaced, it is very easy to cause the pins to fail to be assembled successfully. For this reason, we propose a positioning device for pin assembly of a lock. Summary of the Utility Model

A semi-circular positioning groove for carrying the lock core is opened at the top of the positioning seat. A clamping mechanism for fixing the lock core is fixedly installed on one side of the positioning seat. An adjusting mechanism for rotating and positioning the position of the lock core is arranged on one side of the clamping mechanism. A displacement mechanism for driving the positioning mechanism to rotate and move is fixedly installed on one side of the positioning seat. A plurality of positioning mechanisms for positioning the pin installation positions of the lock core are fixedly installed at the bottom of the displacement mechanism.

Specific implementation mode

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a positioning device for pin assembly of a lock, including a positioning seat 1 and a positioning mechanism 6. A semi-circular positioning groove 2 for carrying the lock core is opened at the top of the positioning seat 1. A clamping mechanism 3 for fixing the lock core is fixedly installed on one side of the positioning seat 1. An adjustment mechanism 4 for rotating and positioning the position of the lock core is arranged on one side of the clamping mechanism 3. A displacement mechanism 5 for driving the positioning mechanism 6 to rotate and move is fixedly installed on one side of the positioning seat 1. A positioning mechanism 6 for positioning the installation positions of multiple lock core pins is fixedly installed at the bottom of the displacement mechanism 5.

[0018] Among them, by setting the positioning seat 1 and the positioning groove 2, the lock core can be placed. Subsequently, the clamping mechanism 3 drives the adjustment mechanism 4 to move and contact the lock core on one side of the lock core. Subsequently, the clamping mechanism 3 can drive the adjustment mechanism 4 to rotate, and then the lock core can rotate in the positioning groove 2. When the installation position of the top pin of the lock corresponds to the positioning mechanism, the positioning mechanism 6 is inserted into the pin installation position, and the fixed installation of the lock core can be completed. After the lock core is installed, the displacement mechanism 5 drives the positioning mechanism 6 to move up and rotate, so as to facilitate the assembly of the pins.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3, the clamping mechanism 3 includes a first driving cylinder 7, a first mounting plate 8 and a first driving motor 9. The bottom of the positioning seat 1 is fixedly installed with the first driving cylinder 7. The output end of the first driving cylinder 7 is fixedly connected with the first mounting plate 8. One side of the first mounting plate 8 is fixedly installed with the first driving motor 9. The axis of the output end of the first driving motor 9 is coaxial with the axis of the positioning groove 2. A plurality of fixing blocks 24 are fixedly installed on the inner wall of the positioning groove 2. One side of the fixing block 24 is rotatably connected with a ball 25. The adjusting mechanism 4 includes a connecting plate 10 and a rotating seat 11. The output end of the first driving motor 9 is fixedly connected with an "L"-shaped connecting plate 10. One side of the top of the connecting plate 10 is fixedly installed with the rotating seat 11. An arc-shaped avoidance groove is formed on the rotating seat 11.

[0020] After the lock core is placed inside the positioning groove 2, the first driving cylinder 7 drives the first mounting plate 8, the first driving motor 9, the connecting plate 10 and the rotating seat 11 to move, and makes the rotating seat 11 fit against one side of the lock core. Then, the first driving motor 9 can drive the lock core to rotate along the ball 25. When the pin installation position on the top of the lock core corresponds to the positioning mechanism 6, the rotation can be stopped.

[0021] Please refer to Figure 1 and Figure 2 , the displacement mechanism 5 includes a second mounting plate 12, a second driving motor 13, a connecting column 14, a fixing plate 15, a second driving cylinder 16 and a moving plate 17. One side of the positioning seat 1 is fixedly installed with the second mounting plate 12. The second mounting plate 12 is fixedly installed with the second driving motor 13. The output end of the second driving motor 13 is fixedly installed with the fixing plate 15 through the connecting column 14. The fixing plate 15 is fixedly installed with the second driving cylinder 16. The output end of the second driving cylinder 16 is fixedly connected with the moving plate 17. Two limiting sleeves 18 are fixedly installed on the fixing plate 15. A limiting rod 19 is slidably connected inside the limiting sleeve 18. The bottom of the limiting rod 19 is fixedly connected with the moving plate 17.

[0022] After the lock core is installed, the second driving motor 13 drives the connecting column 14, the fixing plate 15, the moving plate 17 and the positioning mechanism 6 to move above the lock core. Then, the second starting cylinder 16 drives the moving plate 17 and the positioning mechanism 6 to fit against the top of the lock core, making the positioning mechanism 6 in a compressed state. During the movement of the moving plate 17, the limiting rod 19 and the limiting sleeve 18 can be used for limiting, so as to ensure that the positioning mechanism 6 will not deviate during the movement.

[0023] Please refer to Figure 1 and Figure 2, the positioning mechanism 6 includes a hollow tube 20, a pin positioning column 21, a fixing piece 22 and a spring 23. The bottom of the moving plate 17 is fixedly installed with the hollow tube 20. The inside of the hollow tube 20 is slidably connected with the pin positioning column 21. The outer surface of the pin positioning column 21 is fixedly connected with the fixing piece 22. The top of the moving plate 17 and on the outer surface of the pin positioning column 21 is fixedly connected with the spring 23. The bottom of the spring 23 is fixedly installed on the top of the fixing piece 22.

[0024] Among them, after the positioning mechanism 6 moves above the lock core, due to the action of the spring 23, the pin positioning column 21 can be retracted into the inside of the hollow tube 20. Subsequently, when the lock core rotates to make the pin positioning column 21 correspond to the position of the pin mounting hole on the lock core, the spring 23 pushes the pin positioning column 21 into the pin mounting hole on the lock core, and the positioning of the lock core can be completed. Subsequently, the displacement mechanism 5 can drive the positioning mechanism 6 to rise and rotate to avoid the pins to be installed.

[0025] During use, first, the lock core can be placed by setting the positioning seat 1 and the positioning groove 2. Subsequently, the clamping mechanism 3 drives the adjusting mechanism 4 to move and contact the lock core on one side of the lock core. Subsequently, the clamping mechanism 3 can drive the adjusting mechanism 4 to rotate. Subsequently, the lock core can be rotated in the positioning groove 2. When the pin mounting position on the top of the lock is corresponding to the positioning mechanism, the positioning mechanism 6 is inserted into the pin mounting position, and the fixed installation of the lock core can be completed. After the lock core is installed, the displacement mechanism 5 drives the positioning mechanism 6 to move up and rotate, so as to facilitate the assembly of the pins. After the lock core is placed inside the positioning groove 2, the first driving cylinder 7 drives the first mounting plate 8, the first driving motor 9, the connecting plate 10 and the rotating seat 11 to move, and makes the rotating seat 11 fit with one side of the lock core. Subsequently, the first driving motor 9 can drive the lock core to rotate along the ball 25. When the pin mounting position on the top of the lock core corresponds to the positioning mechanism 6, the rotation can be stopped. After the lock core is installed, the second driving motor 13 drives the connecting column 14, the fixing plate 15, the moving plate 17 and the positioning mechanism 6 to move above the lock core. Subsequently, the second starting cylinder 16 drives the moving plate 17 and the positioning mechanism 6 to fit with the top of the lock core, so that the positioning mechanism 6 is in a compressed state. During the movement of the moving plate 17, the position can be limited by the limiting rod 19 and the limiting sleeve 18, so as to ensure that the positioning mechanism 6 will not shift during the movement. After the positioning mechanism 6 moves above the lock core, due to the action of the spring 23, the pin positioning column 21 can be retracted into the inside of the hollow tube 20. Subsequently, when the lock core rotates to make the pin positioning column 21 correspond to the position of the pin mounting hole on the lock core, the spring 23 pushes the pin positioning column 21 into the pin mounting hole on the lock core, and the positioning of the lock core can be completed. Subsequently, the displacement mechanism 5 can drive the positioning mechanism 6 to rise and rotate to avoid the pins to be installed.
