Description

Technical Field

[0001] This invention relates to the field of industrial caster manufacturing and processing technology, specifically to an industrial caster assembly fixture with trimming function. Background Technology

[0002] Casters are a general term that includes both swivel casters and fixed casters. Swivel casters, also known as universal casters, have a structure that allows them to rotate 360 ​​degrees; fixed casters do not have a rotating structure and cannot turn.

[0003] Industrial casters are caster products mainly used in factories or mechanical equipment. They can be made of high-grade imported reinforced nylon (PA6), super polyurethane, or rubber. The products have high impact resistance and strength. Fixed casters with fixed brackets and single wheels can only move in a straight line. In factories and warehouses, where goods are frequently moved and the load is heavy (each caster can bear 280-420kg), it is suitable to use thick steel plates (5-6mm) and double-row ball bearings.

[0004] In existing technologies, the assembly process of casters mostly involves manually pressing bearings and manually installing axle brackets. This method of assembly is labor-intensive for workers and results in low factory output efficiency. Moreover, after the casters are assembled, a special trimming process is required, which is often done manually in actual production, making it very troublesome. Therefore, it is particularly important to design an industrial caster assembly fixture with trimming function to solve the above problems. Summary of the Invention
