DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0018] According to Figure 1 、 2 As shown in FIGS.

[0019] The clamping mechanism includes a clamping plate 4, a fixed cavity 5, a first servo motor 6, a worm 7, a worm gear 8, a transmission gear 9, a connecting rod 10 and a hinged rod 11. A fixed cavity 5 is installed at the front end of the installation cavity 3. A first servo motor 6 is installed on one side of the fixed cavity 5. A worm 7 is installed above the interior of the fixed cavity 5. The output end of the first servo motor 6 is connected to one end of the worm 7. A worm gear 8 is meshed below the worm 7. Two transmission gears 9 are installed inside the installation cavity 3, and the two transmission gears 9 are meshed with each other. One end of the worm gear 8 is connected to one end of one of the transmission gears 9. A connecting rod 10 is installed at the front end of the transmission gear 9. One end of the connecting rod 10 is hingedly installed with a clamping plate 4. A hinged rod 11 is hingedly installed below the interior of the installation cavity 3. One end of the hinged rod 11 is hinged to one end of the clamping plate 4. A plastic anti-slip pad is installed on the inner side of the clamping plate 4, and the plastic anti-slip pad can perform anti-slip treatment on automotive parts. During use, the first servo motor 6 is started to drive the worm 7 to rotate. Since the worm 7 and the worm gear 8 are meshed with each other, the worm gear 8 is used to drive the transmission gear 9 to rotate. Since the two transmission gears 9 are meshed with each other, the connecting rod 10 is driven to move. Furthermore, with the cooperation of the hinged rod 11, the connecting rod 10 is used to drive the clamping plate 4 to grab automotive parts. Due to the self-locking design between the first servo motor 6 and the worm 7, the automotive parts are more stable during grasping and not easy to fall. At the same time, since the plastic anti-slip pad is provided on the inner side of the clamping plate 4, the automotive parts are not easy to slide during grasping, thereby greatly improving the stability of the gripper during use.

[0020] The moving mechanism includes a second servo motor 12, a first bevel gear 13, a second bevel gear 14, a threaded rod 15, a threaded sleeve 16, a moving cavity 17 and a limiting structure. The second servo motor 12 is installed on one side above the cavity 1. The first bevel gear 13 is installed on one side above the interior of the cavity 1. The output end of the second servo motor 12 is connected to one end of the first bevel gear 13. A second bevel gear 14 is installed and meshed with one side below the first bevel gear 13. One end of the second bevel gear 14 is installed with a threaded rod 15. A threaded sleeve 16 is arranged on the outer sidewall of the threaded rod 15. A moving cavity 17 is fixedly installed on the outer sidewall of the threaded sleeve 16. One end of the moving cavity 17 extends to the outside of the cavity 1. One end of the moving cavity 17 is connected to the top end of the cylinder 2. When in use, start the second servo motor 12 to drive the first bevel gear 13 to rotate. Since the first bevel gear 13 and the second bevel gear 14 are meshed with each other, the second bevel gear 14 is used to drive the threaded rod 15 to rotate, and then drive the threaded sleeve 16 to move. Therefore, under the limitation of the limiting groove 18 and the limiting block 19, the moving cavity 17 is driven to move by the threaded sleeve 16, and then the gripper is driven to move, making the movement of the gripper more convenient and fast, thus greatly improving the practicability of the gripper in use.

[0021] The limiting structure includes a limiting groove 18 and a limiting block 19. The limiting groove 18 is opened in the interior of the cavity 1. A limiting block 19 is arranged inside the limiting groove 18. One end of the limiting block 19 is connected to the outer side of the moving cavity 17. The inner diameter of the limiting groove 18 is larger than the outer diameter of the limiting block 19. A sliding structure is formed between the limiting groove 18 and the limiting block 19. Two limiting grooves 18 are opened in the interior of the cavity 1. The two limiting grooves 18 are symmetrically distributed about the central axis of the cavity 1. When in use, the mutual cooperation between the limiting groove 18 and the limiting block 19 can be used to limit the movement of the moving cavity 17, making the movement of the moving cavity 17 more stable.

[0022] Working principle: First, connect the cavity 1 with the connecting rod of the production line, and then start the second servo motor 12 to drive the first bevel gear 13 to rotate. Since the first bevel gear 13 meshes with the second bevel gear 14, the second bevel gear 14 is used to drive the threaded rod 15 to rotate, thereby driving the threaded sleeve 16 to move. Therefore, under the limitation of the limiting groove 18 and the limiting block 19, the movable cavity 17 is driven to move by the threaded sleeve 16, thereby driving the gripper to move. Then, start the cylinder 2 to drive the gripper to move downward. Finally, start the first servo motor 6 to drive the worm 7 to rotate. Since the worm 7 meshes with the worm gear 8, the worm gear 8 is used to drive the transmission gear 9 to rotate. Since the two transmission gears 9 mesh with each other, the connecting rod 10 is driven to move. Furthermore, with the cooperation of the hinge rod 11, the clamping plate 4 is driven by the connecting rod 10 to grasp the automotive parts.
