The sheet metal part is placed on the support module 16, and the clamping screw 14 is rotated to move the abutment plate 15 downward to fix the position of the sheet metal part. At the same time, the infrared ranging sensor 19 is used to detect the position between the sensor and the sheet metal part to ensure that the sheet metal part can fit tightly with the support module 16 after it is fixed. When placing and fixing the sheet metal part, the hole position detection mechanism is used to check the hole position of the sheet metal part. Specifically, if the hole position detection rod 31 can pop out from the hole position of the sheet metal part, it meets the requirements. If the hole position detection rod does not pop out, the hole position is unqualified. The hole position can be detected during the fixing process of the sheet metal part, making the operation simpler. During flatness testing, the handheld connecting cylinder 5 pushes the abutment roller 9 to roll on the surface of the sheet metal part where flatness needs to be tested from all directions. The flatness is judged based on the up-and-down movement of the sliding rod 6. The flatness is mainly judged by manually observing the front scale and by using the scale monitoring device 10 to test the rear scale and transmitting the test data to an external system for judgment. At the same time, the side abutment mechanism 17 is used to test the side of the sheet metal part, and the side sliding block 23 pushes the side spring 22 to squeeze the side pressure sensor 21. The pressure is then tested by the side pressure sensor 21 to check whether the rolled edge of the sheet metal part meets the requirements.
