[0002] Thin iron sheet parts are commonly used in industrial production. They play the role of connection and fixed limit, so they are used in large quantities. As the precision requirements become higher and higher, some bending angles require very high matching precision, such as the attached Figure 1 The V-shaped parts in the production process need to be measured for the bending angle after production. The current measurement method is to use three-coordinate projection or manual measurement, which has low measurement accuracy and slow speed. Summary of the Invention

[0011] Furthermore, the test rod includes a driving connecting rod and a test plate, the driving connecting rod is connected to the servo motor, and the test plate is connected to the driving connecting rod at a right angle.

[0012] Beneficial effects of the utility model:

[0013] The utility model measures the bending angle by using three groups of conductive copper sheets. First, a positioning assembly is used to fix one end of a V-shaped part so that the third copper sheet contacts the part. When the motor is rotated, the third copper sheet on the test rod contacts the part, forming a loop and generating an electrical signal. At this time, the feedback angle of the servo motor is recorded as the bending angle of the part. The measurement speed is fast, and production efficiency is improved.
