Technical Field

The application belongs to the technical field of measuring equipment, and particularly relates to a polygonal crimping cable opposite side distance measuring device and measuring method.

background

To join cables to form a unitary body, one common method of joining is to crimp the cables together. The cross section of the crimp cable is generally in a regular hexagon shape, and one of the indexes for detecting whether the crimp is qualified is that three pairs of side distances of the regular hexagon in the cross section meet corresponding technical parameter standards. The traditional method for detecting the edge distance of the crimped cable is that an operator directly measures the edge distance by using a corresponding traditional measuring tool, and under the condition that the operator works for a long time, unnecessary measuring errors or even measuring errors can be brought to measurement due to eye fatigue. Or a large-scale equipment instrument is adopted for detection, although the method can meet the requirement on precision, the operation is complex in most of the time, the detection efficiency is low, and therefore the detection equipment which does not need excessive participation of operators in the test process and is simple to operate is very necessary.
