Description

Technical Field

[0001] This utility model relates to the technical field of abrasion resistance testing machines, and in particular to an abrasion resistance testing machine for abrasive cloth and abrasive paper used for abrasive belt quality testing. Background Technology

[0002] In the field of abrasive belt quality inspection, the abrasion resistance of abrasive cloth and paper is a crucial indicator, directly affecting the service life, processing efficiency, and surface quality of the abrasive belt in practical applications. During the grinding process, the abrasive belt frequently rubs against the workpiece surface, which causes wear on the surface of the abrasive cloth and paper, thus affecting its grinding effect. Therefore, effective testing of the abrasion resistance of abrasive cloth and paper can help manufacturers and users understand the durability of the abrasive belt and provide data support for the optimized design of products.

[0003] Traditional abrasion resistance testing machines for abrasive cloth and paper have shortcomings. They often use manual locking or simple pneumatic cylinder fixing in the sample clamping process. The lack of a precision transmission mechanism may result in uneven clamping force distribution and easy loosening due to vibration, making it difficult to guarantee the stability of long-term testing. At the same time, traditional testing usually uses a single direction, which is difficult to simulate the usage in real-world scenarios and can easily affect the experimental results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sandpaper and abrasion resistance testing machine for sanding belt quality testing.

[0005] This utility model is achieved using the following technical solution: A sandpaper and abrasion resistance testing machine for sanding belt quality testing, comprising a fixed base plate, a support rod fixedly connected to the top of the fixed base plate, a sliding sleeve slidably connected to the outside of the support rod, a connecting plate fixedly connected to the top of the sliding sleeve, a hydraulic rod fixedly connected to the top of the fixed base plate, and a grinding block fixedly connected to the top of the fixed base plate, and further comprising: A grinding mechanism, the grinding mechanism including a movable block slidably connected inside a connecting plate, the movable block having a connecting block fixedly connected inside it; The fixing mechanism includes a mounting block fixedly connected to the bottom of the connecting block, a sliding block slidably connected inside the mounting block, and a fixing plate fixedly connected to the left side of the sliding block.

[0006] As a further improvement to the above solution, the connecting plate is fixedly connected to the top of the hydraulic rod, a drive motor is fixedly connected to the top of the connecting plate, and a transmission rod is fixedly connected to the output end of the drive motor.

[0007] By fixing the connecting plate to the top of the hydraulic rod and mounting a drive motor, a compact layout of the power source and motion actuator is achieved. This design shortens the transmission chain length, reduces energy loss, and improves response speed. Furthermore, the drive motor directly drives the transmission rod, ensuring the high efficiency and stability of power transmission and laying the foundation for subsequent precision motion control.

[0008] As a further improvement to the above solution, the transmission rod is rotatably connected inside the connecting plate, a rotating disk is fixedly connected to the outside of the transmission rod, and a connecting column is rotatably connected inside the rotating disk.

[0009] The above technical solution, through the configuration of the external rotating disk and internal connecting column of the transmission rod, converts the rotational motion into an eccentric trajectory output and transmits power, providing a structural basis for testing.

[0010] As a further improvement to the above solution, a connecting rod is rotatably connected to the outside of the connecting column, and the end of the connecting rod away from the connecting column is rotatably connected to the inside of the connecting block.

[0011] As a further improvement to the above solution, a servo motor is fixedly connected to the back of the mounting block, and a rotating rod is fixedly connected to the output end of the servo motor. The rotating rod is rotatably connected inside the mounting block.

[0012] The above technical solution involves installing a servo motor on the back of the mounting block to directly drive the rotating rod, thereby achieving precise digital force control, ensuring a constant output of clamping force, and providing power for the entire fixing mechanism.

[0013] As a further improvement to the above solution, a first bevel gear is fixedly connected to the outside of the rotating rod, a threaded rod is rotatably connected to the inside of the mounting block, and a second bevel gear is fixedly connected to the outside of the threaded rod.

[0014] As a further improvement to the above scheme, the second bevel gear meshes with the first bevel gear, and the sliding block is threadedly connected to the outside of the threaded rod.

[0015] Through the above technical solution, the sliding block and threaded rod, combined with the micro-control capability of the servo motor, enable the fixed plate to form a bidirectional symmetrical clamping method, ensuring that the sample is subjected to uniform force and the deformation is controllable.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a servo motor to drive the rotation of the rotating rod and the first bevel gear, combined with the meshing transmission between the second bevel gear and the threaded rod, to drive the sliding block to slide inward along the thread direction. This structure enables the fixed plate to form a uniform and controllable clamping force on the sandpaper / abrasive cloth on the mounting block, achieving positional stability of the sample during the testing process and preventing displacement caused by vibration or friction. This ensures the consistency of the wear trajectory and the reliability of the data. At the same time, the first and second bevel gears are used to achieve precise control and long-term maintenance of the sample clamping force, effectively improving the accuracy of repeated tests.

[0017] This invention adjusts the height of the connecting plate by retracting the hydraulic rod, and then drives the transmission rod, rotating disk, and connecting column to form an eccentric rotational motion. This structure converts rotational kinetic energy into linear reciprocating motion of the connecting rod, which in turn drives the moving block to move the mounting block horizontally back and forth. This mechanical linkage causes periodic relative motion between the sandpaper / abrasive cloth and the grinding block, simulating the cyclic wear process under actual working conditions. Combined with the smooth loading capability of the hydraulic system, it can accurately reproduce the wear resistance performance of materials under different pressures, providing real data support for quality assessment under dynamic load conditions.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0021] Please combine Figure 1-5 This embodiment of an abrasion resistance testing machine for abrasive belt quality testing includes a fixed base plate 1, a support rod 11 fixedly connected to the top of the fixed base plate 1, a sliding sleeve 12 slidably connected to the outside of the support rod 11, a connecting plate 13 fixedly connected to the top of the sliding sleeve 12, a hydraulic rod 14 fixedly connected to the top of the fixed base plate 1, and a grinding block 15 fixedly connected to the top of the fixed base plate 1. It also includes: The grinding mechanism 2 includes a movable block 207 that is slidably connected inside the connecting plate 13, and a connecting block 206 is fixedly connected inside the movable block 207. The fixing mechanism 3 includes a mounting block 301 fixedly connected to the bottom of the connecting block 206, a sliding block 307 slidably connected inside the mounting block 301, and a fixing plate 308 fixedly connected to the left side of the sliding block 307.

[0022] The connecting plate 13 is fixedly connected to the top of the hydraulic rod 14, and the top of the connecting plate 13 is fixedly connected to the drive motor 201. The output end of the drive motor 201 is fixedly connected to the transmission rod 202.

[0023] The transmission rod 202 is rotatably connected inside the connecting plate 13. The outside of the transmission rod 202 is fixedly connected to the rotating disk 203, and the inside of the rotating disk 203 is rotatably connected to the connecting column 204.

[0024] A connecting rod 205 is rotatably connected to the outside of the connecting post 204, and the end of the connecting rod 205 away from the connecting post 204 is rotatably connected to the inside of the connecting block 206.

[0025] The drive motor 201 can drive the transmission rod 202 to rotate, and the transmission rod 202 drives the rotating disk 203 to rotate. As the rotating disk 203 rotates, it can drive the connecting column 204 to rotate, thereby driving the connecting rod 205 to reciprocate. Then, the connecting rod 205 drives the connecting block 206 to reciprocate, and the moving block 207 to reciprocate inside the connecting plate 13, and finally drives the mounting block 301 to reciprocate.

[0026] A servo motor 302 is fixedly connected to the back of the mounting block 301. A rotating rod 303 is fixedly connected to the output end of the servo motor 302. The rotating rod 303 is rotatably connected inside the mounting block 301.

[0027] The rotating rod 303 is externally fixedly connected to a first bevel gear 304, the mounting block 301 is internally rotatably connected to a threaded rod 305, and the threaded rod 305 is externally fixedly connected to a second bevel gear 306.

[0028] The second bevel gear 306 meshes with the first bevel gear 304, and the sliding block 307 is threadedly connected to the outside of the threaded rod 305.

[0029] The servo motor 302 is started to drive the rotating rod 303 to rotate, which in turn drives the first bevel gear 304 to rotate, thereby driving the second bevel gear 306 to rotate synchronously. In turn, the second bevel gear 306 drives the threaded rod 305 inside it to rotate. When the threaded rod 305 rotates, it can drive the sliding block 307 to slide into the mounting block 301, and the fixed plate 308 connected to the sliding block 307 clamps and fixes the sandpaper or abrasive cloth that is attached to the mounting block 301.

[0030] The implementation principle of the abrasion resistance tester for abrasive belt quality testing in this embodiment is as follows: When in use, the sandpaper or abrasive cloth to be tested is first attached to the mounting block 301, and both sides are placed between the fixing plate 308 and the mounting block 301. At this time, the servo motor 302 can be started to drive the rotating rod 303 to rotate inside the mounting block 301, and drive the first bevel gear 304 outside to rotate. Since the first bevel gear 304 and the second bevel gear 306 mesh with each other, when the first bevel gear 304 rotates, it will drive the second bevel gear 306 to rotate synchronously, thereby causing the second bevel gear 306 to drive the threaded rod 305 inside to rotate. Since the sliding block 307 is threaded to the outside of the threaded rod 305, when the threaded rod 305 rotates, it can drive the sliding block 307 to slide into the mounting block 301, and the sandpaper or abrasive cloth attached to the mounting block 301 is clamped and fixed by the fixing plate 308 connected to the sliding block 307. After fixing, the hydraulic rod 14 can be activated to retract, lowering the height of the connecting plate 13, thereby lowering the height of the mounting block 301, so that the sandpaper or abrasive cloth on its surface can fit into the grinding block 15. At this time, the drive motor 201 can be activated to drive the transmission rod 202 to rotate inside the connecting plate 13, and the transmission rod 202 drives the external rotating disk 203 to rotate. As the rotating disk 203 rotates, it drives the connecting column 204 to rotate, thereby driving the connecting rod 205 to reciprocate. Then, the connecting rod 205 drives the connecting block 206 to reciprocate, and the moving block 207 to reciprocate inside the connecting plate 13, finally driving the mounting block 301 to reciprocate, thereby testing the sandpaper or abrasive cloth.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
