Description

Technical Field

[0001] This utility model relates to the field of test benches, and in particular to a visual friction and wear test bench. Background Technology

[0002] A friction and wear test bench is an experimental device used to simulate the frictional contact process of materials or components under actual working conditions. It is mainly used to evaluate the wear resistance, coefficient of friction, surface damage characteristics and other properties of materials.

[0003] Chinese patent application number CN202110293734.3 discloses a test bench for testing the wear of buoy anchor chains. The bench uses a servo motor in the drive mechanism to drive a rectangular block to rotate, which in turn drives one end of the anchor chain to rotate back and forth, simulating the torsion state of the anchor chain. Furthermore, the bench can drive a U-shaped moving block to move, thereby simulating the torsion angle within a certain range, thus obtaining more test data and improving the accuracy of the test.

[0004] However, most existing friction and wear testing benches do not consider the influence of lubricating oil on the friction and wear of workpieces during the friction and wear test. Therefore, the data obtained from the test is not sufficiently contrasting and the test data may not be complete. To address this, we propose a visual friction and wear testing bench. Utility Model Content

A PLC controller is fixedly connected to the front end of the test bench body.

[0016] Furthermore, the clamping assembly includes a pair of electric push rods, which are fixedly connected to the outside of the side plate of the sealing cover. The output end of each electric push rod is fixedly connected to an output shaft, and a clamping plate is fixedly connected to the outside of the output shaft.

[0031] Reference Figures 1-5 As shown, the lubricating oil spray assembly 3 includes a lubricating oil tank 301, which is placed on the upper end of the test bench body 1.

The top plate of the sealing cover 2 is provided with sliding grooves 310 at both the upper and lower ends. A strong magnetic block 311 is slidably connected inside the upper sliding groove 310. Limiting grooves 312 are provided on the front and rear sides of the inner wall of the lower sliding groove 310. Limiting blocks 313 are slidably connected inside the limiting grooves 312.

[0032] By setting up the lubricating oil spray assembly 3, during testing, a normal test is first conducted and data is recorded. Then, the strong magnetic block 311 is pushed and pulled left and right. The magnetic force of the magnetic block drives the magnetic metal block 314 below to move synchronously along the slide groove 310 below, thereby driving the nozzle 318 to move left and right. The position of the nozzle 318 is adjusted according to the position of the workpiece wear test. The delivery pump 303 is turned on, and then the flow regulating valve 306 is opened to adjust the spray flow. The lubricating oil in the lubricating oil tank 301 is drawn through the input pipe 304 to the output pipe 305, and then delivered to the hose 309, the bend pipe 317 and the nozzle 318. The lubricating oil is sprayed from the nozzle 318 onto the part to be tested first, and then the test is conducted and the data is recorded. This allows for the generation of comparative data, making the test data more complete.

[0033] Reference Figures 1-5 As shown, the input pipe 304 extends into the interior of the lubricating oil tank 301 and is fixedly connected to the lubricating oil tank 301, the output pipe 305 extends into the interior of the sealing cover 2 and is detachably connected to the sealing cover 2, and the locking screw 308 is threadedly connected to the flange 307 and the sealing cover 2.

[0035] Reference Figures 1-2 As shown, the test component 4 includes a linear motor guide rail 401, which is fixedly connected to the lower end of the top plate of the sealing cover 2.

A linear motor guide rail 406 is fixedly connected to the lower end of the connecting post 405. A linear motor moving base 407 is slidably connected to the lower end of the linear motor guide rail 406.

[0037] The linear motor mover base 402 drives the linear motor guide rail 406, the linear motor mover base 407, and the grinding block 412 to move back and forth. The setting of the connecting column 405 reduces the height of the linear motor guide rail 406, so that the linear motor guide rail 406 will not interfere with the movement of the nozzle 318, etc. The linear motor mover base 407 can drive the grinding block 412 to move left and right, thereby adjusting the position of the grinding block 412 and performing friction and wear tests on different parts of the workpiece.

[0038] Reference Figures 1-2 As shown, a hydraulic cylinder 408 is fixedly connected to the lower end of the linear motor actuator 407. An output rod 409 is fixedly connected to the output end of the hydraulic cylinder 408. A drive motor 410 is fixedly connected to the lower end of the output rod 409. A transmission shaft 411 is fixedly connected to the output end of the drive motor 410. A grinding block 412 is fixedly connected to the lower end of the transmission shaft 411.

[0039] The hydraulic cylinder 408 drives the output rod 409, drive motor 410, transmission shaft 411, grinding block 412 and other components to move up and down, which can apply pressure to workpieces of different thicknesses. The drive motor 410 drives the transmission shaft 411 and grinding block 412 to rotate, which can further apply friction to the workpiece, thereby enabling friction and wear testing of the workpiece.

[0040] Reference Figures 1-2 As shown, multiple laser displacement sensors 413 are fixedly connected to the lower end of the top plate of the sealing cover 2. The multiple laser displacement sensors 413 are arranged at equal intervals. A PLC controller 414 is fixedly connected to the front end of the test bench body 1.

[0041] By setting up a laser displacement sensor 413, the surface morphology change of the workpiece can be measured non-contactly, the displacement after the friction and wear test can be obtained, and the data can be transmitted to the PLC controller 414 for data analysis and storage.

The output shaft 502 is slidably connected to the sealing cover 2.

[0043] By setting an electric push rod 501, the electric push rod 501 drives the output shaft 502 and the clamping plate 503 to move left and right, placing the workpiece on the upper end of the test bench body 1, and then using the clamping plate 503 to clamp the workpiece and prevent it from shifting.

One end of the transparent sealing plate 6 is hinged to the sealing cover 2 via a damping hinge, and the end of the transparent sealing plate 6 away from the damping hinge is magnetically connected to the sealing cover 2.

[0045] By setting a transparent sealing plate 6, the situation inside the sealing cover 2 can be observed during testing.

[0046] Specific implementation process: The electric push rod 501 drives the output shaft 502 and the clamping plate 503 to move left and right, placing the workpiece on the upper end of the test bench body 1. The clamping plate 503 can then be used to clamp the workpiece to prevent it from shifting.

[0047] Then, without spraying lubricating oil, the test is carried out. The linear motor mover seat 402 drives the linear motor guide rail 406, the linear motor mover seat 407, and the grinding block 412 to move back and forth. The setting of the connecting column 405 reduces the height of the linear motor guide rail 406, so that the linear motor guide rail 406 will not interfere with the movement of the nozzle 318, etc. The linear motor mover seat 407 can drive the grinding block 412 to move left and right, thereby adjusting the position of the grinding block 412 and performing friction and wear tests on different parts of the workpiece. The hydraulic cylinder 408 drives the output rod 409, the drive motor 410, the transmission shaft 411, and the grinding block 412 to move up and down, which can apply pressure to workpieces of different thicknesses. The drive motor 410 drives the transmission shaft 411 and the grinding block 412 to rotate, which can further apply friction to the workpiece, thereby performing friction and wear tests on the workpiece.

[0048] The laser displacement sensor 413 non-contactly measures the changes in the surface morphology of the workpiece, obtains the displacement after the friction and wear test, and transmits the data to the PLC controller 414 for data analysis, storage, and other operations.

[0049] Then, push and pull the strong magnetic block 311 left and right. The magnetic attraction of the magnetic block drives the magnetic metal block 314 below to move synchronously along the slide groove 310 below, thereby driving the nozzle 318 to move left and right. Adjust the position of the nozzle 318 according to the position of the workpiece wear test, turn on the delivery pump 303, and then open the flow regulating valve 306 to adjust the spray flow. The lubricating oil in the lubricating oil tank 301 is drawn through the input pipe 304 to the output pipe 305, and then delivered to the hose 309, the bend pipe 317 and the nozzle 318. Spraying from the nozzle 318, the lubricating oil is sprayed on the part to be tested first, and then the test is carried out and the data is recorded. In this way, comparative data can be obtained, making the test data more complete.
