Abstract

The invention relates to an assembly detection device for a motor shell positioning bushing. The detection device comprises a base body (1), a supporting base (3), a positioning ring (4), a supportingarm (5), a pressing block (8), a first lever (9), a first weight frame (13), a top block (16), a second lever (23), and a second weight frame (24). According to the invention, the displacement of thepositioning bushing under the action of a certain axial force is measured by an indicating gauge on the supporting arm (5). The device is simple in structure, convenient to install and high in precision, and can be applied to the displacement test and the displacement measurement work of the positioning bushings of types of motor shells under axial pressure.

Description

technical field [0001] The invention belongs to a motor casing test and measurement technology, in particular to an assembly detection device for a positioning bush of a motor casing. Background technique [0002] When the existing motor housing is assembled, the size guarantee from the end face of the positioning bush to the end face of the housing, the verticality requirements of the inner hole of the housing to the end face of the positioning bush, and the displacement of the assembly tightness under the design pressure, etc., due to the positioning bushing It is difficult to control the magnitude of the force when measuring the force and displacement of the sleeve after assembly, and the measurement needs to be measured immediately when the positioning bush is under the design pressure. At the same time, when testing and measuring different products, the overall design of the fixture is required, so that each type of product needs to design a special fixture. As a resul...
