Elastic clamp sleeve circumferential positioning and clamping device for shaft parts

Abstract

The invention belongs to the technical field of automobile part detection, and provides an elastic clamp sleeve circumferential positioning and clamping device for shaft parts. The elastic clamp sleeve circumferential positioning and clamping device comprises a supporting assembly, a positioning assembly, a clamping assembly and a detection assembly. A wedge-shaped ring and an elastic clamp sleeveare arranged, so that the shaft parts can be moved to the upper part of a fixture along with a mechanical arm and other mechanisms during the detection and positioning of the shaft parts, then the shaft parts are put into a nylon positioning sleeve for accurate circumferential positioning, the end surfaces of the shaft parts are compressed and positioned by a positioning sleeve pressing cover, then a clamping air cylinder extends out, the elastic clamp sleeve is pushed through the wedge-shaped ring to deform, and the shaft parts are clamped. The elastic clamp sleeve circumferential positioning and clamping device for shaft parts solves the following problems: a current general positioning method of the shaft parts uses an imitation fixture or make a limit block to position in circumferential direction by using the production shape difference, the direct contact wear between the parts and the fixture in the positioning method is prone to causing product surface damage, and if the product surface is smooth, it is difficult to position in the circumferential direction.

Description

technical field [0001] The invention belongs to the technical field of auto parts detection, in particular to a circumferential positioning and clamping device for an elastic jacket of a shaft part. Background technique [0002] Shaft parts are often used in the automotive field, and the shaft parts of planetary gears are mainly used in automotive reducers and other parts. In order to ensure product quality, the shaft parts of planetary gears need to be tested before they leave the factory. Especially in the automatic loading and unloading field, the automatic clamping and positioning of the end faces and circumferential directions of different shaft parts may easily cause damage to the parts. [0003] At present, the general positioning method of shaft parts is to use profiling jigs, or use the difference in product shape to make limit blocks to position their circumferential direction, but the direct contact between parts and fixtures in this positioning method can easily ...
