Reducing clamp for damping bushing

Abstract

The invention provides a reducing clamp for a damping bushing. The reducing clamp comprises a base, a clamp, a plurality of Halves and a pressing head. The clamp is fixed on the base, the clamp is cylindrical, a shrinkage hole is formed in the middle, the inner wall of the shrinkage hole is obliquely arranged, and the diameter of the shrinkage hole is gradually reduced from top to bottom; an inclined part is arranged on the outer wall of the Half, and a diameter shrinkage part and a limiting part are arranged on the inner wall of the Half; the plurality of Halves are distributed in the shrinkage hole in an annular array manner, the inclined parts of the plurality of Haves form an inverted circular truncated cone shape, and the diameter shrinkage parts form a cylinder shape to clamp a diameter shrinkage section; the limiting parts form a cylindrical shape and are distributed in an annular array around a non diameter shrinkage section; the pressing head comprises a contact part and a stress part; the stress part is knocked to enable the contact part to extrude the Halves downwards, when the Halves move downwards, the inclined parts slide along the inner wall of the shrinkage hole, the plurality of Halves get close gradually, and the diameter shrinkage parts extrude and reduce the diameter of the diameter shrinkage section till the limiting parts makes contact with the outer wall of the non diameter shrinkage section.

Description

Technical field [0001] The present invention relates to automotive suspension bushing technology, and particularly relates to a reduced-diameter shock absorbing liner clamps. Background technique [0002] In the prior art, as part of the meet performance requirements of the vehicle, often with the inner and outer damping hub metal structure, (common material 20 # steel, aluminum), rubber filling formed of a hollow outer annular portion inner employed. Presence shrinkage after curing rubber bush, the metal bush type requires a reduced diameter damping hub, eliminating the stress of deformation of rubber, increasing the durability of the damping bush. [0003] To achieve reduced diameter tooling are numerous, but not well controlled size reduced in diameter, is likely to cause bigger or smaller, and additional surface irregularities easily formed burr, indentation, etc., resulting in poor appearance quality, pass rate. Inventive content [0004] The present invention addresses def...

AI Technical Summary

Problems solved by technology

[0003] There are a lot of tooling to achieve diameter reduction, but the diameter reduction size cannot be well controlled, and it is easy to cause the size to be too large or too small. In addition, the surface is prone to unevenness, burrs, indentations, etc., resulting in poor appearance quality and low pass rate.
