In addition, the existing size detection fixture also has some shortcomings to some extent. Since the sizes of automobile sheet metal parts are different, the universality of the size detection fixture is required to be high.

[0014] 1. By setting a universal clamping mechanism, the user can adjust the position of the clamping frame according to the size of the sheet metal part. The user pulls the clamping frame upward to move it away from the inside of the fixture frame. Then, the user places the clamping frame at the designated position on the surface of the fixture frame, so that one end of the clamping frame moves to the bottom of the fixture frame. At this time, the clamping frame drives the fixing block to slide inside the fixing groove. Under the combined action of the fixing groove and the fixing block, the clamping frame is guided. Then, the clamping frame drives the connecting block to move, so that the connecting block drives the positioning clip to lock into the positioning slot. Under the locking action of the positioning clip and the positioning slot, the clamping frame is stably installed on the surface of the fixture frame.

Thus, when using the dimensional inspection fixture, sheet metal parts of different sizes can be clamped and fixed on the surface of the fixture frame, making the dimensional inspection fixture more versatile.

[0015] 2. By setting a precise placement mechanism, the second electric push rod inside the tank is controlled to work.

Under the action of the stabilizing suction cup inside the holding tank, the sheet metal part is placed more accurately, so that the sheet metal part does not have any skew or displacement on the surface of the fixture frame. This realizes the function of precise placement of the sheet metal part by the dimensional inspection fixture, so that the dimensional inspection fixture can accurately place the sheet metal part on the surface of the fixture frame when using it, making the measurement of the surface of the sheet metal part by the dimensional inspection fixture more accurate.

[0016] 3. By setting up a multi-angle detection mechanism, the third electric push rod inside the fixed cylinder is controlled to work. Under the action of the third electric push rod, the moving column moves inside the lifting plate. At this time, the moving column drives the block to slide inside the lifting plate. At this time, the block drives the rotating ball to move. Under the action of the rotating ball, the block moves faster inside the lifting plate. When the block moves inside the lifting plate, the block drives the third detection plate to move at the bottom of the lifting plate until it contacts the surface of the sheet metal body. According to the position of the third detection plate corresponding to the lifting plate, the user can observe the scale on the surface of the lifting plate to obtain the longitudinal dimension data of the sheet metal body. This realizes the function of the dimension detection fixture to measure the dimensions of the sheet metal body at different angles. Thus, the dimension detection fixture can automatically measure the dimensions of the sheet metal body at different angles when in use, making the dimension detection fixture more effective in measuring the dimensions of the sheet metal body surface.
