Further, the input terminal of the output end of controller and cylinder be electrically connected, the input terminal of controller with apart from biography
The output end of sensor is electrically connected.
Further, support frame is connected with bolt of fixing plate.
The utility model has the beneficial effects that:
1, workpiece for measurement is fixed by fixed plate and movable plate, by starting cylinder, compresses workpiece, generate arc
Degree, and then workpiece is tested, it is convenient to use, it can quickly measure the limit radian of workpiece.
2, the bending surplus of outer surface when the gap between fixed plate and movable plate further releases workpiece inner bending, with
This improves bending test effect and prevents improper damage of the workpiece in bending test.
3, the present invention is by installing control cabinet in the side of rack, during the test, when test article surface is cracked
When, it can stop in time, guarantee the accuracy of test data.
