[0012] In a preferred embodiment, the inner wall of the bracket is provided with a guide groove, and a guide strip is fixedly installed on the outer edge of the push rod. The side of the guide strip away from the push rod is slidably connected to the inner wall of the guide groove.

[0013] By adopting the above technical solution, the push rod that moves up and down can be guided, thereby ensuring that the push rod can move up and down stably in a vertical state.

[0014] In a preferred embodiment, there are two of each of the track groove, slider, and clamp, and the two track grooves, sliders, and clamps are symmetrically arranged on the outer side of the guide rail. Both sliders are threaded to the outer edge of the bidirectional lead screw.

[0015] By adopting the above technical solution, a drive motor can be used to rotate a bidirectional lead screw, which in turn drives two sliders to move synchronously, thereby adjusting the distance between the two clamps and further positioning the lock cylinder.

[0016] In a preferred embodiment, the top of the guide rail is provided with a groove, the slider is adapted to slide and connect to the inner wall of the groove, and a ring is fixedly installed on the inner wall of the groove. The end of the bidirectional lead screw away from the motor is rotatably connected to the inner wall of the ring.

[0017] By adopting the above technical solution, the bidirectional lead screw can be positioned during rotation, ensuring the stability of the bidirectional lead screw during rotation and preventing it from easily shifting or swaying in position.

[0018] The beneficial effects of this application are:

[0019] This lock cylinder retaining ring assembly device uses a drive cylinder to move a push rod to push the retaining ring positioning ring downwards, thereby pressing the retaining ring into the lock cylinder slot and thus achieving installation. This eliminates the need for manual pressing, making it highly efficient and preventing hand injury.

[0020] This lock cylinder retainer assembly device uses a drive motor to rotate a bidirectional lead screw, which in turn drives two sliders to move synchronously, thereby adjusting the distance between the two clamps. This allows for lock cylinder positioning and facilitates the positioning of lock cylinders of different sizes and shapes using the sliders, clamps, and round holes, ensuring stability during assembly with the retainer.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Reference Figure 1-4 A lock cylinder snap ring assembly device includes a base plate 1, a limit switch 2 fixedly installed on the top of the base plate 1, a guide rail 3 installed on the top of the base plate 1, a motor 4 fixedly installed on the outer side of the guide rail 3, a bidirectional lead screw 5 fixedly connected to the power output shaft of the motor 4, a slider 8 threadedly connected to the outer edge of the bidirectional lead screw 5, a slide block 6 fixedly installed on the top of the slider 8, a clamp 9 fixedly installed on the top of the slide block 6, a circular hole 10 opened in the inner wall of the clamp 9, a return spring 11 fixedly connected to one end of the circular hole 10, and a sliding column 12 fixedly connected to the other end of the return spring 11.

[0028] See Figure 2 The inner wall of the slide block 6 is provided with a track groove 7. The slider 8 is fixedly installed on the inner wall of the track groove 7. The inner wall size of the track groove 7 is consistent with the outer size of the guide rail 3, so that the slider 8 can be used to drive the slide block 6 to slide stably on the outer wall of the guide rail 3, thereby adjusting the position of the clamp 9, and then using the two clamps 9 to clamp and position the lock cylinder.

[0029] See Figure 3 The sliding pin 12 is adapted to slide and connect to the inner wall of the round hole 10. The sliding pin 12 is made of rubber. There are several round holes 10, return springs 11 and sliding pins 12. The several round holes 10, return springs 11 and sliding pins 12 are evenly distributed inside the clamp 9, so that the sliding pin 12 can be compressed and retracted into the round hole 10. In this way, multiple sliding pins 12 can be used to contact the lock cylinder, which can be used for positioning the lock cylinder and is convenient for positioning lock cylinders of different sizes.

[0030] See Figure 1 and Figure 4 A bracket 13 is fixedly installed on the top of the base plate 1, and a cylinder 14 is fixedly installed on the top of the bracket 13. A push rod 15 is fixedly connected to the power output shaft of the cylinder 14, and a snap ring positioning ring 16 is fixedly connected to the bottom of the push rod 15, so that the snap ring can be installed inside the snap ring positioning ring 16, thereby driving the cylinder 14 to drive the push rod 15 and the snap ring positioning ring 16 to move downward, which can be used to press the snap ring into the positioned lock cylinder, thereby facilitating the assembly of the snap ring lock cylinder.

[0031] See Figure 4 The inner wall of the bracket 13 is provided with a guide groove 18, and a guide strip 17 is fixedly installed on the outer edge of the push rod 15. The side of the guide strip 17 away from the push rod 15 is slidably connected to the inner wall of the guide groove 18, so that it can guide the push rod 15 that moves up and down, thereby ensuring that the push rod 15 can move up and down stably in a vertical state.

[0032] See Figure 2 There are two track grooves 7, two sliders 8 and two clamps 9. The two track grooves 7, two sliders 8 and two clamps 9 are symmetrically arranged on the outside of the guide rail 3. The two sliders 8 are threaded to the outer edge of the bidirectional lead screw 5, so that the motor 4 can drive the bidirectional lead screw 5 to rotate, which in turn drives the two sliders 8 to move synchronously, realizes the adjustment of the distance between the two clamps 9, and further can position the lock cylinder.

[0033] See Figure 2 The top of the guide rail 3 is provided with a slide groove, the slider 8 is adapted to slide and connected to the inner wall of the slide groove, and a ring is fixedly installed on the inner wall of the slide groove. The end of the bidirectional lead screw 5 away from the motor 4 is rotatably connected to the inner wall of the ring, so that the bidirectional lead screw 5 can be positioned during rotation, ensuring the stability of the bidirectional lead screw 5 during rotation, and ensuring that it will not easily shift or swing in position during rotation.

[0034] Working principle: First, the drive motor 4 drives the bidirectional lead screw 5 to rotate, which in turn drives the two sliders 8 to move synchronously, realizing the adjustment of the distance between the two clamps 9. Then, the lock cylinder is fixed in the clamping area. Then, the snap ring can be manually placed into the snap ring positioning ring 16. Then, the cylinder 14 is driven to move, and the push rod 15 drives the snap ring positioning ring 16 to move downward. Then, the snap ring positioning ring 16 presses the snap ring into the lock cylinder slot, thus realizing the installation. At the same time, after the limit sensor switch 2 senses the end of the stroke, the cylinder 14 returns and automatically resets, ready for the next assembly.
