Description
technical field [0001] The invention relates to the field of wall thickness measurement, in particular to an automatic measurement device and method for the wall thickness of a cylindrical part. Background technique [0002] At present, there are mainly five types of thickness gauges that are widely used: 1. Hand-held micrometer thickness gauges. Using a micrometer to measure thickness, this manual measurement method is relatively traditional and has a low degree of automation. When measuring the thickness of a large number of parts, it takes a long time and the work efficiency is low. Due to the human eye reading, errors are inevitable. 2. Magnetic thickness gauge. Thickness measurement of non-ferromagnetic materials using magnetic methods. When measuring thickness, place the magnetic probe on one side of the material to be tested, and place the corresponding steel ball on the other side. The Hall effect sensor on the probe can measure the distance from the probe tip to t...
