Description

Technical Field

[0001] This utility model belongs to the technical field of conveying devices, specifically a positioning and clamping device for conveying nuts. Background Technology

[0002] The full name of a nut conveyor is a vibrating automatic nut conveyor. It is generally used in conjunction with welding equipment. If it is conveyed by hand, the efficiency is low. More importantly, it can cause serious safety accidents due to operational errors. Therefore, the demand for nut positioning and conveying devices is increasing.

[0003] Meanwhile, a nut positioning and conveying device with the publication number CN221115926U is disclosed, including a base plate. The base plate is provided with an interval feeding mechanism. The interval feeding mechanism includes a drive box and a second rotating shaft. A mounting bracket is fixedly connected to the drive box. A motor is fixedly installed on the mounting bracket. The output end of the motor is fixedly connected to the first rotating shaft. An active dial is fixedly connected to the first rotating shaft. The active dial is provided with teeth. A grooved wheel is fixedly connected to the second rotating shaft. The grooved wheel is provided with multiple sliding grooves. The active dial is meshed with the grooved wheel. The second rotating shaft is rotatably connected to the drive box.

[0004] The aforementioned nut positioning and conveying device can only clamp during use, and lacks stability during clamping, which may cause the nut to fall off during clamping and handling. It cannot accurately position the nut during clamping, which increases the working efficiency of the clamping jaws. The jaws cannot be adjusted in angle, and when clamping nuts at different angles, the jaws need to be replaced. If the distance is insufficient, the jaws cannot be extended, and longer jaws need to be replaced for operation.

[0005] Therefore, a positioning and clamping device for conveying nuts is proposed to address the above problems. Utility Model Content

[0035] Working principle and process of a positioning and clamping device for conveying nuts:

[0036] A support plate 2 is installed on the rear side of the upper end face of the base plate 1. A crossbeam 3 is installed on the inner side of the support plate 2. A motor 5 is installed on the rear side of the inner side of the crossbeam 3. A square fixing plate 6 is installed on the front end of the motor 5. A threaded rod 4 is installed inside the square fixing plate 6. The motor 5 drives the threaded rod 4 to rotate, which can drive the moving plate 7 to move. A moving block 14 is installed on the outer side of the threaded rod 4. The moving plate 7 is installed on the right side of the moving block 14. A connecting block 8 is installed on the right side of the moving plate 7. A liquid is installed on the right side of the connecting block 8. The hydraulic telescopic column 9 is fixed to the movable plate 7 via the connecting block 8 for easy movement. A connecting plate 10 is installed on the right side of the hydraulic telescopic column 9, and a rotating shaft 11 is installed at the lower end of the connecting plate 10. A connecting body 13 is installed inside the rotating shaft 11, and a cylinder 12 is used to fix the connecting body 13 to the rotating shaft 11. A negative pressure tank 15 is installed on the lower right side of the connecting body 13, and a rotating shaft 16 is installed on the lower left and right sides of the negative pressure tank 15. A gripper is installed inside the rotating shaft 16. 17. Install anti-slip blocks 18 on the inner side of the gripper 17. Install a cylindrical barrel 19 inside the negative pressure tank 15. The nut is fitted through the cylindrical barrel 19. Rotate the gripper 17 with the rotating shaft 16 to make the anti-slip blocks 18 on the inner side of the gripper 17 clamp the outer side of the nut, making it less likely for the nut to fall off during movement. Install a support column 21 on the front of the upper end of the base plate 1. Install a drive box 20 on the upper end of the support column 21. Install a rotating shaft 23 on the inner side of the drive box 20. Install a conveyor belt 2 on the outer side of the rotating shaft 23. 2. The drive box 20 drives the rotating shaft 23 to rotate, which in turn drives the conveyor belt 22 to rotate, thus conveying the nuts on the conveyor belt 22. A lifting box 24 is installed at the upper rear of the base plate 1. A telescopic rod 25 is installed inside the lifting box 24, and a lifting plate 26 is installed on top of the telescopic rod 25. The lifting plate 26 can receive the nuts on the conveyor belt 22 by lifting the lifting plate 26, preventing the nuts from falling off during the conveying process, and making it convenient for the gripper 17 to pick up the nuts. This serves as a positioning and gripping device for conveying nuts.
