The invention discloses a detection device for the unevenness of the wall thickness of a bellows, which includes a support positioning mechanism and a measuring mechanism; the support positioning mechanism includes a bottom plate and three sets of support positioning components arranged on the bottom plate; the support positioning component includes and The connecting plate fixedly connected to the bottom plate and the support shaft installed on the connecting plate, a square positioning plate is installed above the support shaft, a support rod is installed on the side wall of the square positioning plate, and a circular positioning plate is installed above the square positioning plate; The measuring mechanism includes a bracket and a lever dial gauge installed on the bracket. The invention uses a compact adjustable mechanical device, which is suitable for the special detection of the unevenness of the wall thickness of the two corrugated structures of the outer convex and the inner concave, and can quickly obtain the value of the unevenness of the wall thickness, which improves the detection efficiency and also The foundation of mechanical structure is laid for the development of automatic special detection device suitable for mass production.
Description
technical field [0001] The invention belongs to a contact measuring device for wall thickness unevenness, in particular to a detection device for bellows wall thickness unevenness. Background technique [0002] The corrugated pipe is made of opaque material, 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, high detection cost; three-coordinate measuring machine needs to frequently replace the probe detection, the steps are complicated, the process is cumbersome, and the detection efficiency is low. Contents of the invention [0003] The present invention is proposed in order to overcome the disadvantages of high cost and low efficiency in the original detection method of the unevenness of the wall thickness...
