Each first equal-height screw 3 is sleeved with a first spring 31 between the fixing plate 1 and the mounting frame 2. The first equal-height screw 3 and the first spring 31 allow the whole clamping force testing tool to shake within a range covering assembly tolerance and machining tolerance in the calipers in a small range, and the problem that the tool for automatically placing the sensor needs to be aligned is solved.
Referring to fig. 1 and 2, the testing assembly includes a pressure sensor base plate 42 connected to the mounting frame 2, and a pressure sensor top plate 41 parallel to the pressure sensor base plate 42, and a pressure sensor 4 is disposed between the pressure sensor base plate 42 and the pressure sensor top plate 41. The mounting rack 2 is provided with a first supporting plate 21 parallel to the pressure sensor bottom plate 42, a second equal-height screw 5 penetrates through the first supporting plate 21, the second equal-height screw 5 penetrates through the first supporting plate 21 to be connected to the pressure sensor bottom plate 42 in a threaded mode, a second spring 51 located between the first supporting plate 21 and the pressure sensor bottom plate 42 is sleeved on the second equal-height screw 5, and the second equal-height screws 5 are arranged in parallel. The second equal-height screw 5 and the second spring 51 allow the pressure sensor bottom plate 42 to shake under the action, and the problem of sliding and clamping stagnation caused by the fact that the thrust plate and the brake pad back plate are not parallel is solved.
Referring to fig. 2 and 3, after the product is positioned, the clamping force test floating mechanism descends, the product motor rotates to drive the thrust plate to advance, the pressure sensor bottom plate 42 is pushed to advance, and after the pressure sensor 4 contacts the pressure sensor top plate 41, the whole body moves until the pressure sensor contacts the product brake pad back plate, and then the clamping force test is started. A reset component for pushing the pressure sensor top plate 41 back to the initial position is arranged on the side surface of the mounting frame 2. In this embodiment, the reset assembly includes a reset cylinder 6 fixed on the side surface of the mounting frame 2, and the driving end of the reset cylinder 6 abuts against the side surface of the pressure sensor top plate 41. The reset cylinder 6 is used for pushing the pressure sensor bottom plate 42 and the pressure sensor top plate 41 to initial positions, and the EMB product calipers are prevented from being collided during the next automatic test.
