[0002] Connectors, also known as plugs and sockets, generally refer to electrical connectors, which are devices that connect two active components to transmit current or signals. Connectors manufactured in factories require polishing equipment to remove burrs and defects from the connector surface, making the surface smoother and flatter, increasing the contact area and contact tightness, helping to reduce contact resistance, improve current transmission efficiency, and enhance the stability and reliability of the connection.

[0003] In the prior art, such as Chinese patent CN221517168U, a burr-removing device for connector production is disclosed, including a worktable; a polishing mechanism is installed on the side wall of the worktable; a base is fixedly connected to the side wall of the worktable; and a support frame is fixedly connected to the top of the base.

[0004] Although the aforementioned patent allows the equipment to clamp and fix connectors of different sizes through the cooperation between the screw, clamping block and fixing plate, it is necessary to rotate two screws to fix the two sides of the connector. This fixing method is cumbersome, which wastes time when fixing and disassembling the connector and affects the grinding efficiency of the equipment. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 - Figure 5As shown, in this embodiment, a grinding device for connector processing includes a worktable 1. A guide frame 2 is arranged above the worktable 1. A U-shaped connecting frame 4 is fixedly connected to the lower end of the guide frame 2. Two clamping plates 6 are slidably connected to the inner wall of the U-shaped connecting frame 4. Push-pull rods 5 are rotatably connected to one side of each of the two clamping plates 6. A pull rod 3 is slidably connected to the middle of the inner wall of the U-shaped connecting frame 4. The outer surfaces of the pull rod 3 are rotatably connected to one end of each of the two push-pull rods 5. A placement groove 7 is opened in the middle of the upper end of the guide frame 2. A gear groove 8 is opened on one side of the outer surface of the pull rod 3. A rotating rod 10 is rotatably connected to the inner wall of the worktable 1. The outer surface of the rotating rod 10 is... A drive gear 9 is fixedly connected to the side. The outer surface of the drive gear 9 meshes with the inner wall of the gear groove 8. By placing the connector on the placement groove 7 and rotating the rotating rod 10, the pulling rod 3 slides in the U-shaped connecting frame 4. The two push-pull rods 5 on the pulling rod 3 pull the two clamping plates 6 closer to each other, so that the two clamping blocks 23 fix the connector. When the polished connector is removed from the placement groove 7, the rotating rod 10 is rotated in the opposite direction to make the two clamping plates 6 move away from each other, so that the two clamping blocks 23 release the connector from restriction, and then the connector can be removed. This structure is simple, easy to operate, shortens the time for fixing and disassembling the connector, and improves the polishing efficiency of the equipment.

[0024] like Figure 2 and Figure 3 As shown, both sides of the U-shaped connecting frame 4 are fixedly connected with connecting ears 21, and the inner walls of the two connecting ears 21 are threaded with fixing bolts 22. One end of the two fixing bolts 22 is threadedly connected to the inner top of the workbench 1. Through the structural design of the connecting ears 21 and fixing bolts 22, it is convenient to install the guide frame 2 and clamping plate 6 and other structures on the workbench 1 to fix the connector.

[0025] like Figure 1 and Figure 3 As shown, a fixed ring 18 is fixedly connected to one side of the workbench 1, and a hexagonal connecting rod 19 is fixedly connected to one end of the rotating rod 10. A hexagonal limiting ring 20 is slidably connected to the outer surface of the hexagonal connecting rod 19. One side of the hexagonal limiting ring 20 is slidably engaged with one side of the fixed ring 18. By pushing the hexagonal limiting ring 20, one side of the hexagonal limiting ring 20 is slidably engaged in the fixed ring 18, thereby connecting the hexagonal connecting rod 19 and the fixed ring 18 together, preventing the rotating rod 10 from rotating, and ensuring that the clamping plate 6 will not move during grinding.

[0026] like Figure 3 and Figure 4As shown, each of the two clamping plates 6 has a mounting groove 25 on one side. The inner walls of the two mounting grooves 25 are slidably connected to clamping blocks 23. Each of the two clamping blocks 23 has a return spring 24 fixedly connected to one side. One end of the two return springs 24 is fixedly connected to one side of the inner wall of the two mounting grooves 25 respectively. Through the structural design of the return springs 24 and clamping blocks 23, the clamping force of the clamping blocks 23 on the connector is prevented from being too large, which could damage the connector.

[0027] like Figure 1 and Figure 2 As shown, a protective cover 11 is fixedly connected to the upper end of the workbench 1, and a sealing door 12 is rotatably connected to one side of the protective cover 11. A transparent glass 13 is fixedly installed on the inner wall of the sealing door 12. Through the structural design of the protective cover 11 and the sealing door 12, the metal chips polished by the grinding equipment 14 are prevented from running out and affecting the working environment of the factory workshop.

[0028] like Figure 1 and Figure 2 As shown, a grinding device 14 is fixedly installed on one side of the inner wall of the protective cover 11. The grinding disc of the grinding device 14 is located in the middle of the upper part of the guide frame 2. Through the structural design of the grinding device 14, the connector is deburred.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, a collection cover 17 is fixedly connected to one side of the upper end of the workbench 1, and a dust collection box 15 is fixedly installed on one side of the bottom inside the workbench 1. The output end of the dust collection box 15 is fixedly connected to one side of the collection cover 17. A suction fan 16 is provided on one side of the dust collection box 15, and the output end of the suction fan 16 is fixedly connected to the input end of the dust collection box 15. A filter screen 27 is fixedly installed on one side of the inner wall of the dust collection box 15. The filter screen 27 is located at the output end of the suction fan 16. A cleaning box 26 is slidably connected to the other side of the inner wall of the dust collection box 15. The connector in the placement slot 7 is polished by the polishing equipment 14. The protective cover 11 and the sealing door 12 prevent metal debris from floating in the factory workshop. When the suction fan 16 is turned on, the collection cover 17 sucks the polished metal debris into the dust collection box 15, thereby collecting the metal debris and preventing the metal debris from affecting the working environment of the factory workshop and ensuring the health of the staff.

[0030] This utility model provides a grinding device for connector processing, the specific working principle of which is as follows:

[0031] When polishing the connector, first place the connector on the placement slot 7, pull the hexagonal limiting ring 20 to slide it out of the fixing ring 18, releasing the restriction of the hexagonal connecting rod 19, then rotate the rotating rod 10 to make the pulling rod 3 slide in the U-shaped connecting frame 4. The two push-pull rods 5 on the pulling rod 3 pull the two clamping plates 6 closer to each other, so that the two clamping blocks 23 fix the connector. Push the hexagonal limiting ring 20 to slide one side of the hexagonal limiting ring 20 into the fixing ring 18. Using the grinding equipment 14, the connector is ground. At the same time, the suction fan 16 is turned on, and the collection cover 17 sucks the ground metal debris into the dust collection box 15 to collect the metal debris. After grinding, the hexagonal limiting ring 20 is pulled out and slid out of the fixed ring 18 to release the restriction of the hexagonal connecting rod 19. The rotating rod 10 is rotated in the opposite direction to make the two clamping plates 6 move away from each other, so that the two clamping blocks 23 release the restriction of the connector. Then the connector is removed, and the grinding is completed.
