A distance sensor for detecting the distance between the first electromagnet 420 and the second electromagnet 421 is arranged between the first electromagnet and the second electromagnet, and the extending thickness of the clamping head 425 can be detected in real time by the distance sensor, so that the automatic adjustment can be carried out according to the program setting.

When the clutch friction plate clamping device is used, firstly, the positioning screw 307 is rotated, so that the positioning screw 307 is separated from the positioning hole 305, at the moment, the limiting position of the movable frame 304 is released, the movable frame 304 is pulled by the handle 308 to move to one side of the device, at the moment, the clutch friction plate is placed on one side of the fixed disc 403, so that the clamping blocks 405 are positioned on the inner side of the clutch friction plate, then, the positioning nut 416 is rotated by rotating the positioning nut 416 to move and drive the positioning sleeve 412 to slide into the limiting sleeve 413, at the moment, the positioning sleeve 412 extrudes the limiting sleeve 413, the limiting sleeve 413 extrudes the movable sleeve 410, the movable sleeve 410 drives the movable arm 409 to move, the movable arm 409 drives the clamping heads 425 to move, so that the clamping heads 425 clamp and fix the clutch friction plate, then, the movable frame 304 is pulled by the handle 308 to reset the movable frame 304, and at the moment, the clutch friction plate corresponds to the rotating assembly 2; the friction performance of the clutch plates can be verified by the test head 214.

When the friction plate thickness is required to be adjusted, by controlling the first electromagnet 420 to be electrified and the second electromagnet 421 to be electrified, meanwhile, the electromagnetic roller is controlled to be powered off, so that magnetic repulsion force is generated between the first electromagnet 420 and the second electromagnet 421, the second electromagnet 421 drives the ferromagnetic sliding block 422 to move leftwards, at this time, the first electromagnetic bolt and the second electromagnetic bolt lock the two pin shafts, so that the second electromagnet 421 moves to the left to drive the ferromagnetic sliding block 422 to move to the left, the ferromagnetic sliding block 422 moves to the left to drive the movable arm 409 and the push plate 423 to move to the left, because the traveler 424 is not movable along the length of the stud 402, and because there is a range of motion between the pusher plate 423 and the traveler 424, thereby make push pedal 423 extrusion spring, make push pedal 423 drive clamping head 425 slide to fixed disk 403 along the electromagnetic roller jointly to make the device can be adapted to the friction disc of different thickness.

When the abrasion degree of the clamping heads 425 needs to be adjusted, the position of a single certain clamping head 425 is adjusted, the clamping force of the clamping heads 425 on the friction plate is kept constant, the pressure value detected in real time according to the pressure sensor is used, when the pressure value detected by the pressure sensor is smaller than a preset value, the corresponding electromagnetic rollers are controlled to be electrified, the first electromagnet 420 is electrified, the second electromagnet 421 is electrified, magnetic repulsion force is generated between the first electromagnet 420 and the second electromagnet 421, then the first electromagnetic bolt and the second electromagnetic bolt are controlled to be contracted, the two pin shafts are unlocked, under the action of the magnetic repulsion force, the second electromagnet 421 drives the push plate 423 and the sliding plate 424 to slide outwards together until the pressure value detected in real time by the pressure sensor is equal to the preset value, and therefore the clamping force of the clamping heads 425 on the friction plate is increased.

In the process of detecting the performance of the friction plate, when the extending thickness of the clamping head 425 is required to be adjusted according to the real-time thickness of the clutch friction plate, so that the clamping of the clamping head 425 does not affect the detection of the performance of the subsequent friction plate, firstly, at least three first electromagnets 420 distributed in an array are controlled to be electrified and the second electromagnets 421 are controlled to be electrified, and the corresponding electromagnetic rollers are controlled to be powered off, so that magnetic attraction is generated between the first electromagnets 420 and the second electromagnets 421, and the second electromagnets 421 drive the ferromagnetic sliding block 422 to move towards the right side, because the two pin shafts are locked by the first electromagnetic pins and the second electromagnetic pins at the moment, the second electromagnets 421 move towards the right side, and the ferromagnetic sliding block 422 moves towards the right side to drive the movable arm 409 and the push plate 423, because the sliding plate 424 cannot move along the length direction of the stud 402, and because a movable range exists between the push plate 423 and the sliding plate 424, the push plate 423 drives the clamping heads 425 to slide towards the fixed disk 403 along the electromagnetic roller together, so that the clamping heads 425 are adjusted in the detection process to be suitable for the real-time thickness of the clutch friction plate, and then the extending thickness of the rest clamping heads 425 is adjusted in the same way, so that the clamping of the clamping heads 425 does not affect the detection of the performance of the subsequent friction plate; through the control, the invention can adjust the extending thickness of the clamping head 425 while ensuring the stable clamping force on the friction plate and realizing non-stop detection in the process of detecting the clamping head 425 so as to adapt to the real-time thickness of the clutch friction plate, thereby improving the detection efficiency.

It should be emphasized that, in the whole detection process, when the first electromagnet 420 is in the power-on stage, the first electromagnet 420 is powered on to generate a magnetic field, so as to generate magnetic attraction to the ferromagnetic rotating shaft, so that the ferromagnetic rotating shaft is locked with the positioning sleeve 412, meanwhile, the second electromagnet 421 is plugged with the through groove 418 of the limiting sleeve 413 to form limiting, and meanwhile, the limiting sleeve 413 forms limiting in the circumferential direction with the stud 402 through the movable sleeve 410, the movable arm 409, the push plate 423, the sliding plate 424 and the fixed disk 403, so as to avoid the situation that in the detection process, the clamping force of the clamping head 425 on the friction plate is influenced due to backward movement of the positioning sleeve 412 caused by the looseness of the positioning nut 416, so that performance detection data is inaccurate or the friction plate is loosened, dropped and damaged.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
