Description

[0002] In mechanical production and assembly, there are a lot of assembly work between sleeves and shafts. Traditionally, sleeve and shaft assembly is mostly done by manual handling of the sleeves. If the sleeve is large in size and heavy in weight, manual handling is difficult and there are safety hazards. Automated equipment with special fixtures are required to clamp the sleeves for assembly. This patent relates to a fixture for assembling barrel-shaped parts, which belongs to the field of assembly fixtures.

[0003] Manual handling of the shaft sleeve assembly is very inconvenient, time-consuming and labor-intensive when the parts are large and heavy, and the parts are easy to fall off, causing safety accidents or parts damage;

[0004] When using automated equipment to carry a fixture to clamp the sleeve, there is a risk of parts falling off when the part is large and heavy; when the assembly space is narrow, the fixture is likely to interfere with the surrounding environment; if it is a thin-walled cylindrical sleeve, the fixture clamping is likely to cause deformation of the part.
