Abstract

The invention discloses a wall thickness unevenness detecting device of bellows, comprising a supporting and positioning mechanism and a measuring mechanism. The supporting and positioning mechanism comprises a baseboard and three sets of supporting and positioning assemblies arranged on the baseboard. Each supporting and positioning assembly comprises a connecting board fixedly connected to the baseboard and a supporting shaft installed on the connecting board. A square positioning board is arranged on the supporting shaft. A supporting rod is arranged on a side wall of the square positioning board. A round positioning board is arranged on the square positioning board. The measuring mechanism comprises a support and a dial test indicator arranged on the support. By use of the compact and adjustable mechanical device, the wall thickness unevenness detecting device can be applied to special tests for the unevenness of wall thickness of outer convex bellows and inner concave bellows. The beneficial effects of the unevenness detecting device are: unevenness of wall thickness can be quickly obtained; detection efficiency is increased; mechanical structure foundation is laid for the development of special automatic detection device suitable for mass production.

Description

technical field [0001] The invention belongs to a contact measuring device for the unevenness of wall thickness, in particular to a device for detecting the unevenness of the wall thickness of a corrugated pipe. Background technique [0002] The corrugated pipe, the material is opaque, the wall thickness of the corrugated part is extremely thin, and the corrugated contour is narrow and deep. The current ultrasonic thickness gauge probe size cannot be used; the two-dimensional optical coordinate measuring machine can only measure the corrugated section, and the corrugated pipe needs to be cut. damage, and the detection cost is high; the CMM needs to replace the probe frequently for detection, the steps are complicated, the process is cumbersome, and the detection efficiency is low. SUMMARY OF THE INVENTION [0003] The invention is proposed in order to overcome the disadvantages of high cost and low efficiency in the existing method for detecting the unevenness of the wall ...
