[0002] The detection disk for position detection is a tool for measuring the position accuracy of mechanical parts or assemblies. By placing the part to be tested on the detection disk, its deviation and error relative to the reference position can be measured quickly and accurately. This detection disk usually has high-precision scales and rulers, which can help operators to quickly and accurately perform position detection. The detection disk for position detection is widely used in the fields of mechanical manufacturing, assembly and quality control. At present, the position detection of gear workpieces requires the use of calipers to continuously adjust the angle and spacing to compare the tooth angle and specifications on the gear workpiece.
