Description

Technical Field

[0001] This utility model relates to the field of coupler processing technology, specifically to a spot welding device for the end of a coupler conductor rod. Background Technology

[0002] A coupler is an electronic component widely used in circuits for signal transmission and power distribution. Its basic function is to transmit a signal from one circuit to another, or to distribute a signal among multiple circuits.

[0003] Currently, the conductor rod is the component used to transmit signals in the coupler, also called the coupling rod. During the production process, the two ends of the conductor rod need to be welded and fixed inside the coupler. The commonly used method is to use a clamp to fix the coupler shell, and then use a hand-held spot welder to perform the welding work.

[0004] However, the welding process generates toxic and harmful gases, which can damage the health of workers. In addition, workers are prone to fatigue when holding the conductor rod with one hand and the spot welder with the other, which reduces work efficiency. Therefore, improvements are needed.

A controller 11 is fixedly installed on the surface of the workbench 1, and the surface of the controller 11 is equipped with control buttons. By setting up the collection hood 7, the exhaust fan 8 and the air filter box 10, the exhaust fan 8 works, the collection hood 7 collects the toxic and harmful gases generated by welding, and then the toxic and harmful gases are transported to the air filter box 10 through the hose 9. The toxic and harmful gases can be filtered, thereby greatly reducing the harm of toxic and harmful gases to the health of workers.

[0025] The clamping mechanism includes two symmetrically arranged clamping components 12. Each clamping component 12 includes a telescopic cylinder 13 and a clamping plate 14. The telescopic cylinder 13 is fixedly connected to the surface of the workbench 1, and the clamping plate 14 is fixedly connected to the telescopic end of the telescopic cylinder 13. By setting up the clamping mechanism, the coupler housing can be clamped and fixed from both sides using the two clamping components 12. The height of the spot welder 6 can be adjusted by using the crossbeam plate 3 for vertical height adjustment. The front and rear position of the spot welder 6 can be adjusted by using the movable block 4 to slide on the surface of the crossbeam plate 3. This eliminates the need for manual hand-held operation of the spot welder 6, thereby reducing the labor intensity of workers and improving work efficiency.

[0026] A pressure sensor 15 is fixedly connected to the surface of the clamping plate 14, and the pressure sensor 15 is signal-connected to the controller 11. By setting the pressure sensor 15, a safe pressure value can be set for the pressure sensor 15. The clamping plate 14 is driven by the telescopic cylinder 13. The coupler housing can be clamped and fixed by the two clamping plates 14 closing together. When the pressure sensor 15 detects that the pressure has reached the safe pressure value, it can control the telescopic cylinder 13 to stop working by sending a signal to the controller 11, thereby effectively avoiding damage to the coupler housing caused by the excessive clamping of the clamping plate 14.

[0027] A support stand 16 is fixedly connected to the surface of the workbench 1. The crossbeam plate 3 is slidably connected to the inner side of the support stand 16. A servo motor 17 is fixedly connected to the upper end of the support stand 16. An adjusting screw 18 is fixedly connected to the output end of the servo motor 17.

The sleeve 22 is fixedly connected to the surface of the movable block 4, the rotating shaft 24 is rotatably connected to the inner wall of the sleeve 22, and the straight plate 25 is fixedly connected to the lower end of the rotating shaft 24. The torsion spring 23 is disposed between the rotating shaft 24 and the sleeve 22. The surface of the collection cover 7 is provided with a straight through groove 26 that fits into the straight plate 25. By setting the locking assembly 5 and the straight through groove 26, the straight plate 25 will be perpendicular to the straight through groove 26 under the action of the torsion spring 23. By limiting the straight plate 25, the collection cover 7 can be quickly installed and fixed. Alternatively, by rotating the straight plate 25 ninety degrees, the straight plate 25 can be pulled out from the straight through groove 26, which facilitates the disassembly of the collection cover 7 and provides convenience for subsequent cleaning and maintenance.

[0030] The air filter box 10 has a gas filter layer 27 and an activated carbon layer 28 fixedly connected inside by bolts. By setting the gas filter layer 27 and the activated carbon layer 28, toxic and harmful gases entering the air filter box 10 can be filtered.

[0031] Working principle: When the spot welding device at the end of the coupler conductor rod is in use, firstly, the housing limiting block 2 is fixedly installed at a specific position on the surface of the workbench 1 according to the length of the coupler housing. Then, the collecting cover 7 is fixed using the locking assembly 5. The coupler housing is placed on the surface of the workbench 1, and the front end of the coupler housing is limited by the housing limiting block 2. The clamping plates 14 are driven to close together by the two telescopic cylinders 13, which can fix the coupler housing. Then, the coupler conductor rod is placed in the corresponding position inside the housing. The position of the movable block 4 is adjusted, and the locking nut 21 is tightened to fix the movable block 4. Then, the servo motor 17 drives the adjusting screw 18 to rotate, thereby lowering the crossbeam plate 3 and adjusting the height of the spot welder 6. The spot welder 6 can be used to weld the two ends of the coupler conductor rod, thus eliminating the need for manual hand-held spot welder 6, reducing the labor intensity of workers and improving work efficiency. Furthermore, the exhaust fan 8 works, and the collection hood 7 collects the toxic and harmful gases generated during welding. The toxic and harmful gases are then transported to the air filter box 10 through the hose 9, which can filter the toxic and harmful gases, thereby greatly reducing the risk of toxic and harmful gases harming the health of workers.
