Background

The shaft-hole fit is one of the most common fit modes in the field of mechanical maintenance, and includes three types, namely, a clearance fit, an interference fit and a transition fit. Wherein the size of the clearance fit finger hole is larger than that of the shaft; the size of the interference fit finger hole is smaller than that of the shaft; a transition fit is a fit between the first two. In practice, assembly and disassembly is difficult due to corrosion and deformation and tolerance requirements. The shaft hole matching part assembling and disassembling device used in the existing mechanical maintenance does not have two functions of assembling and disassembling at the same time. A press machine is generally selected during assembly, the field is limited, and the universality is not strong; during decomposition, the puller with the structure that the claw and the ejector rod are matched is generally selected, the structural stability is low, the puller is easy to slip, and the using effect cannot be achieved. Therefore, it is necessary to adopt a device which can be applied to shaft hole components with different sizes and has two functions of assembling and disassembling to solve the problems.
