Description

Technical Field

[0001] The utility model relates to the field of copper sleeve processing technology, in particular to a copper sleeve processing fixture. Background Art

[0002] Copper sleeve processing refers to the processing of copper materials to create precision copper sleeve parts. Copper sleeves are commonly used in various mechanical equipment to reduce wear and friction, and provide support and positioning functions. Copper sleeves offer advantages such as good thermal conductivity, strong wear resistance, and high reliability. Therefore, they are widely used in the automotive, machinery, metallurgy, chemical, and other fields. During copper sleeve processing, workers often use fixtures to clamp and secure the sleeves to improve stability and facilitate processing.

[0003] China Utility Model Publication No.: CN221248569U includes a clamping platform with a circular groove in the middle, and clamping mechanisms are provided at both ends of the circular groove. The utility model cooperates with the clamping mechanism, a screw, a movable sleeve, a curved clamping plate, and a crank. When the screw rotates, it drives the movable sleeves on both sides to move in the same direction. When the two movable sleeves move in the same direction, they drive the curved clamping plates to clamp the surfaces of the copper tube on both sides. This allows the outside of the copper tube to be processed. When the inside of the copper tube needs to be processed, the two curved clamping plates are first controlled to move in the same direction until they are close together. Then, the inside of the copper tube is sleeved on the outside of the two curved clamping plates. After that, the crank is reversed, and the crank controls the two curved clamping plates to clamp on both sides of the inner wall of the copper tube. This allows the inside or outside of the copper tube to be clamped without changing the clamping head.

[0004] The applicant found that this patent had some shortcomings in use: after the copper sleeve was clamped and fixed, the position of the copper sleeve itself could not be changed. The staff stood on one side of the copper sleeve to process the copper sleeve. When the other side of the copper sleeve needed to be processed, they needed to walk to the other side of the copper sleeve, which was not convenient.

[0005] Therefore, the utility model designs a copper sleeve processing fixture to solve the problems existing in the prior art. Utility Model Content

[0027] Working principle: When processing the inner wall of the copper sleeve, the outer wall of the copper sleeve can be clamped, and the copper sleeve can be placed between the two vertical arc blocks 10. Then, the wheel 14 is rotated to rotate the positive and negative thread screws 8, and the two vertical arc blocks 10 are driven to approach each other, so that the outer wall of the copper sleeve can be clamped and fixed on both sides. When it is necessary to process the outer wall of the copper sleeve, the wheel 14 can be rotated to make the two vertical arc blocks 10 approach each other to the minimum distance, and then the sleeve is set on the outside of the two vertical arc blocks 10, and then the vertical arc blocks 10 are rotated in the opposite direction to make the two vertical arc blocks 10 move away from each other, so that the vertical arc blocks 10 can tighten and fix the inner walls of the copper sleeve on both sides.
