[0002] The clutch pulley friction plate is a key component of mechanical equipment, especially in automotive transmission systems. It is usually made of wear-resistant and high-temperature-resistant materials, such as metals, ceramics, carbon materials, or composite materials. The selection of these materials is designed to ensure that they maintain stable friction performance under high-intensity and high-temperature environments. The main function of the clutch pulley friction plate is to transmit the power generated by the engine to the transmission system, while allowing the driver to achieve precise control of power transmission by operating the clutch to disengage and engage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-5 As shown, a clamp for testing the friction plate of a clutch pulley includes a cleaning mechanism 1 and an adjustment mechanism 2 above the cleaning mechanism 1. The cleaning mechanism 1 includes a support frame 101, and a motor 106 is fixedly installed in the middle of the bottom surface of the support frame 101. The output shaft of the motor 106 is equipped with an electromagnetic lock, which locks the output shaft when the output shaft of the motor 106 stops rotating.
[0027] The output shaft of motor 106 extends upward into the interior of support frame 101. Several movable slots 105 are formed on the bottom surface of support frame 101, and each movable slot 105 is equidistantly arranged around motor 106. An extension frame 107 is fixedly installed on the bottom surface of support frame 101, below each movable slot 105. A collection box 108 is slidably connected to the inner wall of each extension frame 107. One end of the collection box 108 extends to the outside of the extension frame 107, and a push rod 109 is fixedly connected to the end of the collection box 108 outside the extension frame 107. Figures 4-5As shown, a sealing layer is provided between the extension frame 107 and the collection box 108 to prevent debris from drifting into the external environment;
[0028] Several arc-shaped tubes 110 are also fixedly installed on the bottom surface of the support frame 101. Each arc-shaped tube 110 is located between adjacent extension frames 107, and both ends of each arc-shaped tube 110 are connected to the extension frame 107. Dustproof nets 111 are embedded and fixedly installed on the inner walls of both ends of the arc-shaped tube 110. Figure 5 As shown, the dustproof net 111 prevents debris from clogging the inside of the arc-shaped tube 110;
[0029] A base 113 is fixedly installed on the outer side of the bottom surface of the support frame 101. A negative pressure fan 112 is also fixedly installed at one end of the outer side of the bottom surface of the support frame 101. The inlet of the negative pressure fan 112 is connected to the arc-shaped pipe 110, and the outlet of the negative pressure fan 112 extends to the outer side of the base 113.
[0030] A fence 102 is fixedly installed on one side of the top surface of the support frame 101. Baffles 103 are slidably connected to both sides of the inner wall of the fence 102, and the bottom surfaces of both baffles 103 are slidably connected to the top surface of the support frame 101. A handle 104 is fixedly connected to the outer wall end of each baffle 103, away from the fence 102. Figure 1 As shown, pushing the handle 104 can cause the baffle 103 to retract into the fence 102;
[0031] The adjusting mechanism 2 includes a rotating plate 201, the center of the bottom surface of which is rotatably connected to the center of the inner wall of the support frame 101, and the center of the bottom surface of the rotating plate 201 is also fixedly connected to the output shaft of the motor 106. A pressing groove 202 is provided on the surface of the rotating plate 201 near each moving groove 105. The adjusting mechanism 2 also includes clamping shafts 203, of which several are provided. A threaded shaft 206 is fixedly connected to the top center of each clamping shaft 203. A retaining ring 207 is threadedly connected to the outer wall of the threaded shaft 206, and a washer 208 is fixedly connected to the bottom surface of the retaining ring 207. Figure 2 As shown, the gasket 208 is made of rubber, and the abutment ring 207 falls along the threaded shaft 206, thereby pressing the surface of the friction pad to be tested against the surface of the rotating plate 201 at multiple points.
[0032] An upper limit block 204 is provided at the upper end of the outer wall of the clamping shaft 203, and a lower limit block 205 is provided at the lower end of the outer wall of the clamping shaft 203.

[0033] The working principle of this utility model:
[0034] When using the device, the friction pad to be tested is placed above the rotating plate 201. Then, the motor 106 is started to drive the rotating plate 201 to rotate, and the pressing groove 202 pushes the clamping shaft 203 to slide along the inner side of the moving groove 105. The direction of force on the clamping shaft 203 is changed according to the rotation direction of the rotating plate 201, thereby changing the position of the clamping shaft 203 in the moving groove 105, and thus adjusting the spacing between each clamping shaft 203. Through the above method, the clamping shaft 203 is pressed and fixed against the outer or inner side of the friction pad to be tested.
[0035] Secondly, during the test, the negative pressure fan 112 can be started to create negative pressure inside the arc-shaped pipe 110 and the extension frame 107, so that the debris attached to the surface of the rotating plate 201 can pass through the squeezing groove 202 and the moving groove 105, and then enter the extension frame 107 and fall into the collection box 108. Subsequently, the operator can use the push rod 109 to separate the collection box 108 from the extension frame 107 and clean up the collected debris.
[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
