Problems solved by technology

For the shock absorber with a single cylindrical inner hole, it can be solved by using a micro-tapered solid shaft or an ordinary expansion mandrel, but for a situation where the inner hole is large in taper and has a stepped hole and the end face cannot be used, the micro-tapered solid shaft cannot be used Tighten the shock absorber with the ordinary expansion mandrel (sometimes it can be tightened, but because the expansion sleeve is separated, it brings in a large system error)
The existence of this contradiction is not conducive to quality control

Abstract

The invention discloses a clamping piece for detecting the radial run-out of the side face of a pulley groove of a shock absorber. The clamping piece comprises a mandrel and a locking swivel nut. The mandrel comprises a mandrel body. Three elastic jaws are circumferentially arranged in the middle position of the mandrel body at intervals. The outer walls of the elastic jaws are conic. The middle positions of the inner sides of the elastic jaws are connected with the side wall of the mandrel body through a supporting body. Gaps are formed between the inner sides of the elastic jaws located on the two sides of the supporting body and the side wall of the mandrel body. The elastic jaws can swing around the supporting body, so that the radial distances between the outer walls of the three elastic jaws and the center of the mandrel body are changed. The locking swivel nut is in threaded connection with the front end of the mandrel body. When the mandrel body is sleeved with a pulley of the shock absorber, the pulley of the shock absorber can be driven by the locking swivel nut to be tensioned on the outer walls of the three elastic jaws. The clamping piece can be used for clamping the shock absorber with an inner hole large in taper and with a stepped hole, detection is convenient, and accuracy is high.

Description

technical field [0001] The invention relates to the detection of geometric characteristic items of parts, in particular to a clamping part for detecting the radial runout of the groove side of the belt pulley of the shock absorber. Background technique [0002] In the manufacture of internal combustion engines (automobiles), it is necessary to test the geometric characteristics of shock absorber components, such as the radial runout of the side of the pulley groove of the shock absorber. At present, a special mandrel is generally used to measure on a general-purpose deflection meter. For the shock absorber with a single cylindrical inner hole, it can be solved by using a micro-tapered solid shaft or an ordinary expansion mandrel, but for a situation where the inner hole is large in taper and has a stepped hole and the end face cannot be used, the micro-tapered solid shaft cannot be used Tighten the shock absorber with the ordinary expansion mandrel (sometimes it can be tigh...
