Description

Technical Field

[0001] This utility model relates to the field of friction plate detection technology, specifically a device for detecting the torque borne by a friction plate. Background Technology

[0002] Friction plates are components consisting of a chip and friction linings or friction material layers. They are widely used in mechanical engineering, mechanical parts, and clutches, featuring wear resistance, corrosion resistance, high strength, and long service life. They are crucial for ensuring the safe and reliable operation of mechanical equipment. During the production process, friction plates require torque testing. The friction plates do not brake while the equipment is rotating; rather, they are used when the equipment is stationary, with two friction plates engaged to maintain stability. The maximum static friction force between the two friction plates is utilized. However, currently, there is no equipment on the market that meets the company's torque testing requirements; even existing testing equipment cannot accurately measure the torque of the friction plates.

[0003] The existing technology has the following problems:

[0004] Existing devices for detecting the torque that friction plates can withstand can only manually provide input torque to detect the torque that the friction plate can withstand. They cannot automatically and continuously provide input torque, which reduces the efficiency of detection and cannot meet the requirements of use. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for detecting the torque borne by a friction plate, comprising a rotating tooling platform, a base disposed above one side of the rotating tooling platform, a testing device disposed on the top of the base, a torque sensor disposed on one side of the testing device, a central shaft disposed on one side of the torque sensor, a force-applying lever disposed on one side of the outer surface of the central shaft, a jack nut disposed at the bottom of the force-applying lever, and a torque display connected to the torque sensor.

[0008] As a preferred technical solution of this utility model, the shaft brake test fixing flange is installed on the flange fastener by means of hexagon socket head cap screws, and the size of the shaft brake test fixing flange is adapted to the size of the flange fastener.

[0009] As a preferred embodiment of this utility model, one end of the air pipe connector is connected to an air compressor, and the other end of the air pipe connector is connected to an air pipe. The position of the air pipe connector corresponds to the position of the piston.

[0010] In a preferred embodiment of this invention, the torque sensor and the torque display are electrically connected via a data cable, and the torque sensor is mounted on the testing device via a rotatable connection.

[0011] As a preferred embodiment of this utility model, a torque sensor is fixedly connected to one end of the central shaft, and a force-applying lever is fixedly connected to the other end of the central shaft.

[0012] As a preferred embodiment of this utility model, the bottom end of the jack nut is fixedly connected to the base, and the top end of the jack nut is movably connected to the force-applying lever.

[0013] Compared with the prior art, the present invention provides a device for detecting the torque borne by a friction plate, which has the following beneficial effects:

[0014] This invention relates to a device for detecting the torque applied to friction plates. The testing device sits on a rotating workbench. An air compressor pipe is connected to an air pipe connector, allowing compressed air to enter the device through the pipe and connector. The compressed air pushes a piston inside the device, causing two friction plates to fit tightly together. Rotating a jack nut raises a lever, which in turn applies torque to a torque sensor via a central shaft. The friction plates inside the device prevent the sensor from rotating, thus applying torque to the sensor. A data cable is connected to the torque sensor, with the other end connected to a torque display. When the torque sensor receives torque, it transmits a signal to the display in real time, which automatically records the torque value. When the applied torque exceeds the maximum static friction force provided by the friction plates, the torque sensor rotates and simultaneously outputs a signal indicating the maximum torque received. The torque value is then displayed on the screen. This design makes the device simple, practical, and inexpensive, making it particularly suitable for companies to internally test the quality of purchased friction plates.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Specifically: The torque sensor 4 is connected to a data cable, and the other end of the data cable is connected to a torque display 8. When the torque sensor 4 is subjected to torque, it will transmit a signal to the display in real time, and the display will automatically record the torque value.

[0022] Reference Figure 1 , Figure 2 and Figure 3The testing device 3 includes a reducer mounting base 301, a piston 302 on one side of the reducer mounting base 301, a flange fastener 303 on one side of the piston 302, a shaft brake mounting plate 304 on one side of the flange fastener 303, a connector 305 on one side of the shaft brake mounting plate 304, a brake pad A306 on one side of the connector 305, a brake pad B307 on one side of the brake pad A306, a shaft brake test fixing flange 308 on the outer surface of the brake pad B307, and an air pipe connector 309 on one side of the shaft brake test fixing flange 308. The shaft brake test fixing flange 308 is mounted on the flange fastener 303 by hexagon socket head cap screws, and the size of the shaft brake test fixing flange 308 is adapted to the size of the flange fastener 303.

[0023] Specifically: It facilitates the improvement of the stability of the connection between the axle brake test fixing flange 308 and the flange fastener 303, and at the same time limits the friction plate to improve the stability of the friction plate.

[0024] Reference Figure 1 and Figure 3 One end of the air pipe connector 309 is connected to the air compressor, and the other end of the air pipe connector 309 is connected to the air pipe. The position of the air pipe connector 309 corresponds to the position of the piston 302.

[0025] Specifically: the air pipe is connected to the air pipe connector 309 for easy connection of the air compressor. Compressed air enters the device through the air pipe and air pipe connector 309. At the same time, the compressed air pushes the piston 302 inside the device to make the two friction plates fit tightly together.

[0026] Reference Figure 1 and Figure 2 One end of the central shaft 5 is fixedly connected to the torque sensor 4, and the other end of the central shaft 5 is fixedly connected to the force-applying lever 6; the bottom end of the jack nut 7 is fixedly connected to the base 2, and the top end of the jack nut 7 is movably connected to the force-applying lever 6.

[0027] Specifically: by rotating the jack nut 7, the jack nut 7 can be used to lift the force lever 6 upwards. The rotation of the force lever 6 provides a torque to the torque sensor 4 through the central shaft 5. Meanwhile, the friction plate inside the device prevents the sensor from rotating, thus applying a torque to the torque sensor 4 for torque detection.

[0028] It should be noted that (torque sensor 4 and torque display 8) are well known or can be found by those skilled in the art related to this utility model, and therefore will not be described here.

[0029] The working principle and usage process of this utility model: The testing device 3 sits on the flip-over tooling operating table 1. The air compressor's air pipe is connected to the air pipe connector 309. Compressed air enters the device through the air pipe and air pipe connector 309. The compressed air pushes the piston 302 inside the device, causing the two friction plates to fit tightly together. The jack nut 7 is rotated, causing the jack nut 7 to push the force lever 6 upward. The force lever 6 rotates and provides a torque to the torque sensor 4 through the central shaft 5. The friction plates inside the device prevent the sensor from rotating, thus applying a torque to the torque sensor 4. The torque sensor 4 is connected to a data cable, and the other end of the data cable is connected to a torque display 8. When the torque sensor 4 is subjected to torque, it will transmit a signal to the display in real time. The display automatically records the torque value. When the applied torque is greater than the maximum static friction force provided by the friction plates, the torque sensor 4 will rotate. At the same time, the torque sensor 4 outputs the maximum torque signal it receives, and the torque value will be displayed on the display.
