Description

Technical Field

[0001] The utility model belongs to the technical field of copper-aluminum welding, and particularly relates to a copper-aluminum welding auxiliary structure. Background Art

[0002] Copper-aluminum connecting pipes are generally formed by welding copper pipes and aluminum pipes. When welding existing copper-aluminum connecting pipes, users directly butt the copper pipe and the aluminum pipe together, and then use welding equipment to weld one side of the joint of the copper pipe and the aluminum pipe. After one side is welded, the copper pipe and the aluminum pipe are flipped. When the unwelded part of the copper pipe and the aluminum pipe faces the staff, the staff can use the welding equipment to weld it. This not only has cumbersome operations, but also when the copper pipe and the aluminum pipe are butted, the copper pipe and the aluminum pipe may be misaligned and not on the same axis, reducing the welding quality of the copper pipe and the aluminum pipe. Therefore, a copper-aluminum welding auxiliary structure is needed to solve the above problems. Summary of the Utility Model

[0023] The threaded block 31 is slidably connected to the slide hole 12. By providing the slide hole 12 and the threaded block 31, since the threaded block 31 is slidably connected to the slide hole 12, the slide hole 12 can limit the threaded block 31, so that the threaded block 31 will not rotate under the action of the rotating threaded rod 23, and the threaded block 31 can move smoothly along the axial direction of the threaded rod 23 under the action of the rotating threaded rod 23;

[0024] A movable plate 32 is connected to the threaded block 31. A rotating assembly 4 is arranged inside the movable plate 32. One of the rotating assemblies 4 is connected to the turntable 5.

[0028] Working principle and usage process of the utility model: Move the copper tube and the aluminum tube respectively outside a number of clamping jaws 71, and then move the copper tube and the aluminum tube respectively outside the number of clamping jaws 71. Push the copper tube and the aluminum tube away from each other. Both the copper tube and the aluminum tube push a number of clamping jaws 71 to approach each other through a number of rollers 72 and then move to a position in contact with the rotating plate 43. At this time, the copper tube and the aluminum tube are in a coaxial position. Control the motor 22 to work. The working motor 22 drives two threaded rods 23 to rotate in two first bearings 24 respectively. The two rotating threaded rods 23 drive two threaded blocks 31 to approach each other.
