DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: Figure 1-5As shown, the utility model provides a wave measuring device for the friction plate of a wet dual clutch of an automobile, comprising a workbench 1, a first rotating shaft 11 rotatingly passing through the middle of the workbench 1, a turntable 12 fixedly mounted on the top of the first rotating shaft 11, four support columns 13 evenly distributed in an annular pattern fixedly mounted on the top of the turntable 12, a placement platform 14 fixedly mounted on the top of the support columns 13, a placement groove 15 is provided on the top of the placement platform 14, a limit ring 16 is fixedly mounted on the lower surface of the inner wall of the placement groove 15, and moving blocks 17 are slidably clamped on both sides of the limit ring 16. The opposite ends of the moving block 17 are fixedly installed with clamping blocks 18, and the bottom ends of the two moving blocks 17 are fixedly installed with connecting columns 19. The middle part of the placement table 14 is rotated through by a second rotating shaft 2, and the top of the second rotating shaft 2 is fixedly installed with a disc 21. The limit ring 16 is rotatably sleeved on the disc 21, and the bottom end of the disc 21 is penetrated by an arc groove 22 used in conjunction with the connecting column 19. The top of the placement groove 15 is provided with a friction plate 101, and the upper surface of the workbench 1 is provided with a measuring height ruler 102, and the detection rod of the measuring height ruler 102 is in contact with the friction plate 101.

[0020] The top of the fixing plate 31 is fixed with two symmetrically distributed empty slots 3, and the inside of the empty slots 3 is fixedly installed with a fixing plate 31. The top of the fixing plate 31 is fixedly installed with two symmetrically distributed springs 32. The top of the spring 32 is fixedly installed with a rebound plate 33. The bottom end of each rebound plate 33 is fixedly installed with two symmetrically distributed movable columns 34. The movable columns 34 slide through the fixing plate 31, and the movable columns 34 are located inside the springs 32. A slot 4 is provided on both sides of each placing platform 14, and a locking block 41 is provided for sliding inside the slot 4. A limiting slot 36 is penetrated in the middle of each rebound plate 33 for use with the locking block 41. By setting the locking block 41, the slot 4, and the limiting slot 36, the rebound plate 33 is limited to prevent the rebound plate 33 from rebounding the friction plate 101 under the action of the spring 32 when the friction plate 101 is fixed, thereby affecting the fixation of the friction plate 101.

[0021] An arc-shaped connecting plate 42 is fixedly installed on the side of the two clamping blocks 41 away from the placement table 14, and a handle 43 is fixedly installed on the top edge of the arc-shaped connecting plate 42. By setting the arc-shaped connecting plate 42 and the handle 43, it is more convenient to pull the two clamping blocks 41 at the same time, so that the clamping blocks 41 are disengaged from the corresponding limiting grooves 36, and the rebound plate 33 is not limited.

[0022] A rubber pad 37 is fixedly mounted on the top of each rebound plate 33 . The rubber pad 37 protects the friction plate 101 and prevents the rebound plate 33 from damaging the friction plate 101 when the ripple measurement of the friction plate 101 is performed.

[0023] A limit plate 35 is fixedly installed at the bottom end of each movable column 34. By setting the limit plate 35, the movable column 34 is limited to prevent the rebound plate 33 from exceeding the empty slot 3 too much under the action of the rebound of the spring 32, causing the friction plate 101 to move out of the placement slot 15, fall to the ground, and damage the friction plate 101.

[0024] The two clamping blocks 18 are arc-shaped, so that the clamping blocks 18 and the inner wall of the friction plate 101 fit more closely together, making the friction plate 101 more stable when fixed on the placement groove 15 .

[0025] A first motor 10 is fixedly installed at the bottom end of the workbench 1, and a driving end of the first motor 10 is fixedly installed on the first rotating shaft 11. By setting the first motor 10, when the first motor 10 is started, it drives the first rotating shaft 11 to rotate, thereby driving the turntable 12 to rotate.

[0026] A second motor 23 is fixedly mounted on the bottom end of the placement table 14 , and a driving end of the second motor 23 is fixedly mounted on the second rotating shaft 2 . By setting the second motor 23 , when the second motor 23 is started, the second rotating shaft 2 is driven to rotate, thereby driving the disc 21 to rotate.

[0027] Working principle: In actual use, first place the friction plate 101 on the placement groove 15 and put it on the outside of the connecting clamping block 18, then start the second motor 23 to drive the second rotating shaft 2 to rotate, thereby driving the disc 21 to rotate, and then the arc groove 22 drives the connecting column 19 to slide as the disc 21 rotates, thereby driving the two moving blocks 17 and the clamping block 18 to move to both sides, so that the clamping block 18 fits with the inner wall of the friction plate 101, thereby fixing the friction plate 101 on the placement groove 15, and then fit the detection rod on the measuring height ruler 102 with the friction plate 101, then start the first motor 10 to drive the first rotating shaft 11 to rotate, thereby driving the turntable 12 and the components on the turntable 12 and the friction plate 101 to rotate automatically, and then the ripple measurement of the friction plate 101 is performed;

[0028] When the corrugation measurement of the friction plate 101 is completed, the friction plate 101 is not fixed on the placement slot 15 first, and then the two blocks 41 are pulled outward to disengage the blocks 41 from the corresponding limit slots 36. Then the spring 32 drives the rebound plate 33 to rebound upward without resistance, and the moving column 34 moves upward, thereby popping out a small part of the tested friction plate 101, and then the friction plate 101 is taken out.

[0029] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
