Description

Technical Field

[0002] A double-sided spot welding machine is a mechanical device that adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes press the workpiece to form a certain contact resistance between two layers of metal under the pressure of the two electrodes. When performing spot welding work, a clamping component is required to clamp and position the workpiece to facilitate spot welding work. Therefore, a clamping and fixing mechanism of a double-sided spot welding machine is needed.

[0003] When the existing clamping component is fixedly connected to the double-sided spot welding machine, it generally directly fixes the body part of the double-sided spot welding machine to facilitate the spot welding head to perform spot welding on the clamped workpiece. However, when used on different types of spot welding machines, since the height of the clamping component cannot be freely adjusted, the clamping component has limitations in the process of use.

[0004] After retrieval, the Chinese patent with the publication number CN218775878U discloses a clamping component of a double-sided spot welding machine. This structure can freely adjust the height of the clamping mechanism on the mounting seat according to the use requirements through the designed fixed seat, connecting seat, sliding groove and slider, so as to be applicable to different types of double-sided spot welding machines. At the same time, with the designed limiting groove, limiting block, operation, positioning groove and positioning buckle, the height of the connecting seat can also be firmly limited. Compared with the existing technology, the height adjustment work of the clamping mechanism is greatly facilitated.

[0005] However, the following problems will occur during the use of the above device: The structure can clamp through the clamping plate, but the angle of the clamping plate is fixed, the angle of the clamping plate cannot be adjusted, and it is not convenient to disassemble the clamping plate to disassemble and repair the wear generated on the clamping plate.

The connecting mechanism includes a moving block 6 provided inside the connecting frame 4. A fixing rod 7 penetrates through the inside of the moving block 6. The fixing rod 7 is connected to the connecting frame 4. L-shaped connecting blocks 8 are provided on both sides of the moving block 6. Springs 9 are provided at the bottoms of the two L-shaped connecting blocks 8. One end of the spring 9 is provided with a fixed block. Two connecting grooves are opened on the surface of the connecting frame 4. The fixed block is connected to the connecting groove. Support blocks 10 are provided on both sides of the connecting frame 4. Limit rods 11 are threadedly connected inside the two support blocks 10. One end of the limit rod 11 extends into the inside of the connecting frame 4. One end of the limit rod 11 is threadedly connected to the fixing rod 7. A handle 12 is provided at the other end of the limit rod 11. By driving the limit rod 11 to rotate through the handle 12, the limit rod 11 can be separated from the fixing rod 7. The springs 9 at the bottoms of the L-shaped connecting blocks 8 on both sides of the moving block 6 drive the fixed blocks to move out of the connecting grooves, so that the moving block 6 can be taken out of the connecting frame 4. The moving block 6 drives the fixing rod 7 and the clamping plate 5 to be disassembled from the connecting frame 4, which is convenient for disassembling and repairing the clamping structure on one side of the connecting frame 4.

[0022] Refer to Figure 3 and Figure 4As shown, a rotating mechanism is provided between the slider 3 and the connecting frame 4. The rotating mechanism includes a limiting groove formed on the surface of the slider 3. A rotating plate 13 is threadedly connected inside the limiting groove. The rotating plate 13 is fixedly connected to the connecting frame 4. A plurality of connecting holes are formed on the surfaces of both the rotating plate 13 and the slider 3. Support rods 14 are clamped inside the plurality of connecting holes. U-shaped blocks 15 are arranged at the tops of the two support rods 14. When the angle of the clamping plate 5 needs to be adjusted, rotate the rotating plate 13 between the slider 3 and the connecting frame 4. The rotating plate 13 is threadedly connected to the limiting groove on the surface of the slider 3, so that the angle of the connecting frame 4 and the clamping block 19 can be conveniently adjusted. By clamping the support rods 14 with the connecting holes, the connection between the slider 3 and the rotating plate 13 can be fixed, so that not only can the angle of the clamping plate 5 on one side be driven to be adjusted, but also the connecting frame 4 and the slider 3 can be disassembled.

[0023] Referring to Figure 1 and Figure 5 As shown, a motor 16 is arranged on the top of the fixed frame 2. A lead screw 17 is arranged at the output end of the motor 16. One end of the lead screw 17 extends into the fixed frame 2. The lead screw 17 is connected to the slider 3. The adjusting mechanism includes two moving grooves formed on the surface of the clamping plate 5. Slide rods 18 are arranged inside the two moving grooves. An adjusting block is arranged on the slide rod 18. A clamping block 19 is arranged on one side of the adjusting block. A screw rod 20 is arranged at the bottom of the clamping plate 5. One end of the screw rod 20 extends into the clamping plate 5. The screw rod 20 is connected to the clamping block 19. The clamping block 19 is fixedly installed on the double-sided spot welder through the mounting seat 1. Then, in order to be applicable to different types of spot welding heads, the height of the clamping block can be adjusted for adaptation. The motor 16 drives the lead screw 17 to rotate. The lead screw 17 drives the slider 3 to move. The slider 3 drives the connecting frame 4 and the clamping plate 5 on one side to move, so as to adjust the height of the clamping plate 5. Inside the clamping plate 5, the screw rod 20 can drive the clamping block 19 to move up and down. One side of the clamping block 19 is matched with the slide rod 18 and the adjusting block, so that the clamping block 19 moves more stably when moving.

[0024] The working principle of the present utility model: First, when the clamping block 19 needs to be used, the clamping block 19 can be fixedly installed on the double-sided spot welder through the mounting seat 1. Then, in order to be applicable to different types of spot welding heads, the height of the clamping block can be adjusted for adaptation. The motor 16 drives the lead screw 17 to rotate. The lead screw 17 drives the slider 3 to move. The slider 3 drives the connecting frame 4 and the clamping plate 5 on one side to move, so as to adjust the height of the clamping plate 5. Inside the clamping plate 5, the screw rod 20 can drive the clamping block 19 to move up and down. One side of the clamping block 19 is matched with the slide rod 18 and the adjusting block, so that the clamping block 19 moves more stably when moving.

[0025] Then, when it is necessary to adjust the angle of the clamping plate 5, rotate the rotating plate 13 between the sliding block 3 and the connecting frame 4. The rotating plate 13 is threadedly connected to the limiting groove on the surface of the sliding block 3, so that the angle of the connecting frame 4 and the clamping block 19 can be conveniently adjusted. The support rod 14 is clamped with the connecting hole, so that the connection between the sliding block 3 and the rotating plate 13 can be fixed. This not only allows the clamping plate 5 on one side to be adjusted in angle, but also the connection between the connecting frame 4 and the sliding block 3 can be disassembled. By driving the limiting rod 11 to rotate through the handle 12, the limiting rod 11 can be separated from the fixed rod 7. The springs 9 at the bottom of the L-shaped connecting blocks 8 on both sides of the moving block 6 drive the fixed block to move out of the connecting groove, so that the moving block 6 can be taken out from the inside of the connecting frame 4. The moving block 6 drives the fixed rod 7 and the clamping plate 5 to be disassembled from the connecting frame 4, which is convenient for disassembling and repairing the clamping structure on one side of the connecting frame 4.

[0026] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
