Description

Technical Field

[0001] The utility model relates to the technical field of measuring jigs, and in particular to a polygonal jig. Background Art

[0002] Thin iron sheet parts are commonly used in industrial production. They play the role of connection and fixed limit, so they have a large usage. However, with the development of technology, the design accuracy of parts is getting higher and higher, and the accuracy requirements are also getting higher and higher. For example, Figure 1 The parts shown in the figure need to ensure the angle α between the centers of the two rows of circles. However, the current test routine is to detect the diameter of the circle. There is no better way to detect the angle between the centers of the circles. Only professional measuring equipment can be used. Although this equipment has high detection accuracy, it is slow and requires manual operation one by one, which has high labor costs and low detection efficiency. Summary of the Invention

[0014] The utility model arranges the position sensor according to the measurement angle α, converts the angle measurement into the rotation of the motor, and then inserts the stop rod. If it can be inserted, it means that the angle and diameter are qualified. Multiple groups of parts can be measured at one time according to the angle, which greatly improves the measurement efficiency and saves costs. BRIEF DESCRIPTION OF THE DRAWINGS
