Description

Technical Field

[0001] This utility model mainly relates to the field of copper bushings, specifically to a copper tube clamp for processing self-lubricating bearing copper bushings. Background Technology

[0002] Self-lubricating bearing bushings (usually made of copper alloy matrix inlaid with solid lubricant) are widely used in automobiles, construction machinery, precision instruments and other fields due to their excellent wear resistance, low coefficient of friction and maintenance-free characteristics. The core component of this type of bearing—the copper bushing—is usually made of high-precision copper tubes (such as phosphor bronze tubes, tin bronze tubes, etc.) through multiple precision machining processes (such as turning the outer diameter, inner hole, end face, grooving, drilling and inlaying lubricant, etc.).

[0003] In the processing of copper bushings, the clamping of the copper tube blank is a crucial initial step. Copper tube materials are generally characterized by their softness, ease of deformation, and high requirements for surface finish. Especially for copper tubes used in the manufacture of self-lubricating bearings, the dimensional accuracy (such as roundness, cylindricity, and wall thickness uniformity), geometric tolerances, and surface quality (no scratches or indentations) of the final product directly determine the assembly accuracy, load-bearing capacity, and service life of the bearing.

[0004] During the operation of specific embodiments, the inventors discovered the following defects: Traditional clamps (especially external clamps) have large and concentrated clamping forces, which can easily leave clamp marks and indentations on the outer or inner surface of soft copper tubes, failing to meet the stringent requirements of high surface quality for self-lubricating bearing copper bushings.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
