Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a multi-point continuous spot welding device. Background Technology

[0002] Spot welding is a common joining process in metal processing, widely used in various fields. Traditional spot welding equipment typically uses a single-point welding method, meaning that only one weld point can be processed per welding operation. For workpieces requiring continuous multi-point welding, this single-point welding method is inefficient, and the consistency of weld point positions is difficult to guarantee, affecting product quality.

[0003] In existing technologies, to improve welding efficiency, some equipment uses multiple welding torches working synchronously. However, such equipment typically suffers from the following problems: multiple welding torches require independent drive and control, resulting in bulky equipment. Each welding torch corresponds to a motor or pusher cylinder, which not only increases the cost of the equipment itself but also multiplies the maintenance costs. Secondly, the control logic between different drive components is also quite complex. The coordinated action of multiple welding torches places high demands on the control system, making it prone to timing errors and affecting the weld quality. At the same time, the fixed spacing between each weld point in existing technologies makes it difficult to adapt to the processing requirements of workpieces of different specifications.

[0004] Based on this, the present invention designs a multi-point continuous spot welding device to solve the above problems. Utility Model Content

[0032] The downward drive assembly includes a connecting column 412 and a rotating block 413. The connecting column 412 is fixedly connected to the rear end of the moving plate 409, and the rotating block 413 is rotatably connected to the connecting column 412.

[0038] In this utility model, two tubular workpieces to be spot welded are placed on the carrier platform 2. The motor 303 on the motor fixing plate 304 is started. The rotation of the motor 303 drives the rotation shaft 307 to rotate. The rotation shaft 307 drives the gear ring 301 to rotate. The rotation of the gear ring 301 drives the connecting wall 305 and the inclined pressure plate 306 to make circular motion. When the inclined pressure plate 306 reaches above the connecting column 412 and the rotating block 413, the lower end of the inclined pressure plate 306 contacts the rotating block 413, causing the rotating block 413 to move downward. The downward movement of the rotating block 413 will drive the moving plate 409 and the spot welding head 411 to move downward. The spot welding head 411 contacts the outer wall of the tubular workpiece to perform spot welding. As the gear ring 301 rotates one revolution, all spot welding heads 411 are spot welded. The welded workpiece is removed. The above operation can be repeated to spot weld new workpieces.

[0039] When spot welding is required on tubular workpieces with different inner diameters, loosen the nut on the removal fixture 2, replace it with a fixture 2 of the corresponding size, tighten the nut to fix it, and at the same time rotate the fixing ring adjustment knob 410 so that the end of the fixing ring adjustment knob 410 does not abut against the spot welding head 411, adjust the position of the spot welding head 411, and after the adjustment is completed, rotate the fixing ring adjustment knob 410 so that the end of the fixing ring adjustment knob 410 abuts against the spot welding head 411 to fix it. In this way, spot welding processing can be performed on different tubular workpieces.

[0040] When it is necessary to adjust the number and position of spot welding points, the position of spot welding fixing plate 403 can be adjusted by loosening spot welding nut 406. After the position is adjusted, tighten spot welding nut 406 so that the end of spot welding bolt 405 abuts against the inner wall of inner groove 401 and outer groove 402. When it is necessary to adjust the number of welding points, spot welding fixing plate 403 can be removed by unscrewing spot welding nut 406.
