AI Technical Summary
When clamping circular objects like rotating shafts, traditional welding clamps lack protective structure, resulting in fewer stress points on the clamping plates, which affects the clamping effect and may cause local deformation.
A welding clamp with a protective structure is designed to adjust the angle of the clamp angle with a rubber block that is engaging and connected on the side of the moving clamp and the fixed clamp. The rotating connection between the L-shaped fixing plate and the base is combined with the rotating connection of the clamp angle, and the lead screw, servo motor and worm gear mechanism are used to adjust the clamp angle.
Effectively protect the clamping part, avoid deformation caused by excessive clamping force, improve the processing effect of the rotating shaft, and improve welding efficiency by adjusting the clamp angle.

[0002] A welding clamp is a device used to clamp an object during the welding process. Traditional welding clamps are mainly used to clamp square objects for welding. During the welding process of circular objects such as rotating shafts, due to the lack of a protection structure design, the stress points on both sides of the clamping plate are less, which not only affects the clamping effect, but also easily causes local deformation of the rotating shaft, affecting the practicability of the rotating shaft clamp of the welding clamp. Therefore, we designed a rotating shaft clamp of a welding clamp with a protection structure. Summary of the Invention

Specific implementation mode
[0019] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.
[0020] As Figures 1-4 shown, a rotating shaft fixture of a welding and clamping device with a protection structure according to the present utility model includes a base 1. The top end of the base 1 is rotatably connected with an L-shaped fixing plate 2. One side of the top end of the L-shaped fixing plate 2 is fixedly installed with a fixed clamping block 8. The two side edges of the L-shaped fixing plate 2 are slidably connected with a moving clamping block 4. Arc-shaped grooves are respectively formed on the sides of the fixed clamping block 8 and the moving clamping block 4. Rubber blocks 9 are respectively clamped and connected inside the two arc-shaped grooves.
[0021] Specifically, through the rubber blocks 9 clamped and connected to the sides of the moving clamping block 4 and the fixed clamping block 8, effective protection can be provided for the clamped part, avoiding local deformation of the clamped part due to excessive clamping force and affecting the processing of the rotating shaft.
[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, for a rotating shaft fixture of a welding and clamping device with a protection structure according to the present utility model, a lead screw 5 is rotatably connected between the fixed clamping block 8 and the L-shaped fixing plate 2. The lead screw 5 is threadedly connected to the bottom of the moving clamping block 4. A first servo motor 6 is fixedly installed on the side of the L-shaped fixing plate 2. The first servo motor 6 is fixedly connected to one end of the lead screw 5.
[0023] Specifically, the rotation of the lead screw 5 is driven by the first servo motor 6, and the movement and clamping of the moving clamping block 4 are driven by the rotation of the lead screw 5.
[0024] Clamping grooves 12 are respectively formed at the top and bottom of the two rubber blocks 9. Cavities 10 are respectively formed inside the fixed clamping block 8 and the moving clamping block 4. U-shaped clamping strips 11 are respectively nested and connected to the top and bottom of the cavity 10. One end of the two U-shaped clamping strips 11 passes through the cavity 10 and is clamped and connected to the corresponding clamping groove 12.
[0025] Connection plates are respectively fixed at the other ends of the two U-shaped clamping strips 11. Fixed blocks 13 are respectively fixedly installed at the top and bottom on one side of the cavity 10. Return springs 14 are fixedly installed between the fixed blocks 13 and the connection plates.
[0026] A transmission shaft is rotatably connected to the middle of the cavity 10. One end of the transmission shaft is fixedly installed with a double-sided cam 15. The top and bottom of the double-sided cam 15 are in contact connection with the surfaces of the corresponding connecting plates. The other end of the transmission shaft is fixedly installed with a knob 7.
[0027] Specifically, the rotation of the double-sided cam 15 is driven by the knob 7. The rotation of the double-sided cam 15 pushes the two U-shaped clamping strips 11 to separate, so that the two U-shaped clamping strips 11 are separated from the clamping grooves 12, facilitating the disassembly and replacement of the rubber block 9.
[0028] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in
[0029] Specifically, through the cooperation of the second servo motor 19, the worm gear 18 and the worm 17, the rotation of the rotating shaft 16 is realized. The horizontal angle of the L-shaped fixing plate 2 is adjusted by the rotation of the rotating shaft 16.
[0030] Limit sliding strips 3 are fixedly arranged on both sides of the top of the L-shaped fixing plate 2. Limit sliding grooves are opened on both sides of the bottom end of the moving clamping block 4. The limit sliding grooves are adapted to the limit sliding strips 3.
[0031] In specific implementation, when using this rotating shaft fixture, first connect the power supply according to the requirements. Then place the rotating shaft between the moving clamping block 4 and the fixed clamping block 8. Then turn on the first servo motor 6. The rotation of the first servo motor 6 drives the rotation of the lead screw 5. The rotation of the lead screw 5 drives the movement of the moving clamping block 4. Thus, the rotating shaft is clamped by the fixed clamping block 8 and the moving clamping block 4. When the welding angle needs to be adjusted, turn on the second servo motor 19. The rotation of the second servo motor 19 drives the rotation of the worm 17. The worm 17 meshes with the worm gear 18, thereby driving the rotation of the rotating shaft 16. The rotation of the rotating shaft 16 drives the rotation of the L-shaped fixing plate 2, realizing the horizontal angle adjustment of the rotating shaft.
[0032] When the rubber block 9 needs to be disassembled and replaced, manually rotate the knob 7. The rotation of the knob 7 drives the rotation of the double-sided cam 15. The rotation of the double-sided cam 15 jacks up the two U-shaped clamping strips 11, separating the U-shaped clamping strips 11 from the clamping grooves 12. Then take out the rubber block 9 from the arc-shaped groove to complete the disassembly and replacement of the rubber block 9.
