Description

Technical Field

[0001] This utility model belongs to the field of wear resistance testing technology, and in particular relates to a multi-station wear resistance testing machine. Background Technology

[0002] Abrasion testing machines are devices used to evaluate the abrasion resistance of materials under simulated usage conditions, ensuring that products remain durable in actual applications. They play an important role in many industries. Before conducting abrasion tests, the product to be tested must be fixed and then abrasion tested. Existing abrasion testing machines are usually fixed by a fixed slot or by locking the clamping blocks with threads. However, due to the diversity of products, the flat clamping surface cannot adapt to products with complex shapes, resulting in limited clamping effect and affecting the accuracy of abrasion test data. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-station abrasion resistance testing machine. By setting a main clamping block and a secondary clamping block, specifically by starting a second motor to drive a threaded rod to rotate, the two main clamping blocks are brought closer together by the slider due to the two opposite threads on the threaded rod, clamping the product. At the same time, the secondary clamping block slides inside the main clamping block to fit different product shapes. The anti-slip pad provides a better fixing effect, and the limiting block slides on the inner wall of the limiting groove to prevent the secondary clamping block from detaching from the main clamping block. This solves the problem that existing abrasion resistance testing machines have limited fixing effect on products with complex shapes, which affects the accuracy of abrasion resistance test data.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a multi-station abrasion resistance testing machine, comprising an operating table and testing components. A turntable is rotatably connected inside the operating table. The testing components consist of four components, each including four support blocks. The bottom of each support block is fixedly connected to the top of the turntable. Two threaded rods with opposite threads are rotatably connected to the corresponding sides of the two support blocks on the back side. Sliding rods are fixedly connected to the corresponding sides of the two support blocks on the front side. A motor is fixedly connected to the side of each support block near the threaded rods. The left side of the motor is fixedly connected to the right side of the threaded rods via a coupling. Two sliders are provided on the outer surfaces of both the threaded rods and the sliding rods. A main clamping block is fixedly connected to the corresponding side of each slider. Two auxiliary clamping blocks are slidably connected inside the main clamping blocks. Anti-slip pads are fixedly connected to the corresponding sides of the two auxiliary clamping blocks. The auxiliary clamping blocks are semi-circular in shape. The motor drives the threaded rods to rotate, causing the two main clamping blocks to move closer together for clamping and fixation. Simultaneously, the auxiliary clamping blocks can slide inside the main clamping blocks, conforming to different product shapes and improving the fixing effect, thereby improving the accuracy of the product abrasion resistance test data.

[0006] Furthermore, the slider is threadedly connected to the outer surface of the threaded rod, and the slider is slidably connected to the outer surface of the sliding rod. A limiting groove is formed inside the main clamping block, and two limiting blocks are fixedly connected to the outer surface of the secondary clamping block. The outer surface of the limiting block is slidably connected to the inner wall of the limiting groove. The cooperation between the limiting groove and the limiting block can further ensure the positional accuracy of the secondary clamping block, prevent it from detaching from the main clamping block, and thus improve its stability.

[0007] Furthermore, two electric telescopic rods are fixedly connected to the top of the turntable near the main clamping block. A support frame is fixedly connected to the top of the electric telescopic rods. The electric telescopic rods can adjust the height of the support frame as needed to accommodate products of different heights, increasing the flexibility of the equipment.

[0008] Furthermore, a turntable two is rotatably connected to the front of the support frame, a rotating rod is fixedly connected to the front of the turntable two, and a motor three is fixedly connected to the back of the support frame via a support plate. The output end of the front of the motor three is fixedly connected to the back of the turntable two. The support frame provides a stable support structure for the reciprocating motion component and the grinding component, thereby improving the overall stability of the device.

[0009] Furthermore, the turntable is provided with a slide plate on its front side. The slide plate has a groove inside and is slidably connected to the outer surface of the rotating rod. The support frame is fixedly connected with two limiting blocks on its front side. The two limiting blocks are slidably connected to the left and right sides of the slide plate, respectively. When the turntable rotates, the rotating rod slides on the inner wall of the groove. The limiting blocks are designed to restrict the movement trajectory of the slide plate, thereby allowing the slide plate to move back and forth to achieve multi-directional grinding tests.

[0010] Furthermore, a motor four is fixedly connected to the bottom of the skateboard via a support plate. A turntable three is fixedly connected to the bottom output end of the motor four. A locking block is fixedly connected to the bottom of the turntable three. A locking block contacts a locking block at its bottom. A grinding head is fixedly connected to the bottom of the locking block. The grinding head performs grinding tests on the product under the drive of the motor four. The locking block and locking block can enable quick replacement of the grinding head, improving testing efficiency.

[0011] Furthermore, a button is slidably connected inside the lock block, and a latch is fixedly connected to the bottom of the button. The outer surface of the latch is slidably connected to the inside of the lock block, and a spring is fixedly connected to the bottom of the latch. Two insertion holes are opened at the bottom of the lock block, and two latches are fixedly connected to the top of the locking block. The outer surface of the latches is inserted into the inner wall of the insertion holes, and the outer surface of the latches is in contact with the outer surface of the lock. The locking block can be quickly disassembled by pressing the button. During installation, the spring drives the latches to quickly reset, which improves the speed of installation and disassembly, thereby greatly improving the testing efficiency.

[0012] This utility model has the following beneficial effects:

[0013] This utility model, by setting a main clamping block and a secondary clamping block, specifically by starting motor two to drive the threaded rod to rotate. Since the threaded rod has two threads in opposite directions, the slider will drive the two main clamping blocks to move closer to each other to clamp the product. At the same time, the secondary clamping block slides inside the main clamping block to fit different product shapes. The anti-slip pad provides a better fixing effect. The limiting block one slides on the inner wall of the limiting groove to prevent the secondary clamping block from detaching from the main clamping block, thereby improving the fixing effect and ensuring the accuracy of the product's wear resistance test data.

[0014] This invention features a locking block and a latching block. Specifically, pressing a button causes the locking buckle to slide inside the locking block, disengaging it from the latching block and releasing it from its fixation. Similarly, during installation, pressing the button inserts the latching block into the inner wall of the insertion hole. Releasing the button causes the spring force to reset the locking buckle, bringing its outer surface into contact with the latching block's outer surface for fixation. This allows for quick replacement of the grinding head, improving testing efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0026] Please see Figures 1-6 As shown, this utility model is a multi-station wear resistance testing machine, including an operating table 1 and a testing component 2. A turntable 11 is rotatably connected inside the operating table 1. The number of testing components 2 is set to four, and the testing component 2 includes four support blocks 21. The bottom of the support blocks 21 is fixedly connected to the top of the turntable 11. Threaded rods 211 are rotatably connected to the corresponding sides of the two support blocks 21 on the back side. The threaded rods 211 have two threads in opposite directions.

[0027] The slider 22 is threadedly connected to the outer surface of the threaded rod 211, and the slider 22 is slidably connected to the outer surface of the slide rod 212. The main clamping block 23 has a limiting groove 233 inside. The outer surface of the auxiliary clamping block 231 is fixedly connected to two limiting blocks 234. The outer surface of the limiting blocks 234 is slidably connected to the inner wall of the limiting groove 233. By setting the main clamping block 23 and the auxiliary clamping block 231, specifically by starting the motor 213, the threaded rod 211 is driven to rotate. Since the threaded rod 211 has two threads in opposite directions, the slider 22 will drive the two main clamping blocks 23 to move closer to each other to clamp the product. At the same time, the auxiliary clamping block 231 slides inside the main clamping block 23 to fit different product shapes. The anti-slip pad 232 provides a better fixing effect. The limiting blocks 234 slide on the inner wall of the limiting groove 233 to prevent the auxiliary clamping block 231 from detaching from the main clamping block 23, thereby improving the fixing effect and ensuring the accuracy of the product wear resistance test data.

[0028] Two electric telescopic rods 24 are fixedly connected to the top of the turntable 11 near the main clamping block 23, and a support frame 25 is fixedly connected to the top of the electric telescopic rods 24.

[0029] The support frame 25 is rotatably connected to the front of the turntable 251, and the turntable 251 is fixedly connected to the front of the turntable 251. The support frame 25 is fixedly connected to the back of the motor 253 via the support plate, and the output end of the motor 253 is fixedly connected to the back of the turntable 251.

[0030] The turntable 251 has a slide plate 254 on its front. The slide plate 254 has a slot inside. The slide plate 254 is slidably connected to the outer surface of the rotating rod 252 through the slot. The support frame 25 has two limit blocks 255 fixedly connected to its front. The two limit blocks 255 are slidably connected to the left and right sides of the slide plate 254, respectively.

The bottom of the turntable 261 is fixedly connected to the locking block 27. The bottom of the locking block 27 contacts the locking block 28. The bottom of the locking block 28 is fixedly connected to the grinding head 29.

[0032] A button 271 is slidably connected inside the locking block 27. A latch 272 is fixedly connected to the bottom of the button 271. The outer surface of the latch 272 is slidably connected to the inside of the locking block 27. A spring 273 is fixedly connected to the bottom of the latch 272. Two insertion holes 274 are opened at the bottom of the locking block 27. Two latches 281 are fixedly connected to the top of the locking block 28. The outer surface of the latches 281 is inserted into the inner wall of the insertion hole 274, and the outer surface of the latches 281 is in contact with the outer surface of the latch 272. By setting the locking block 27 and the locking block 28, Specifically, pressing button 271 causes the latch 272 to slide inside the locking block 27. At this time, the latch 272 will disengage from the outer surface of the buckle 281, thereby releasing the fixation of the buckle 28. Similarly, during installation, pressing button 271 inserts the buckle 281 into the inner wall of the insertion hole 274. After releasing the button, the spring 273 will cause the latch 272 to return to its original position, so that the outer surface of the latch 272 contacts the outer surface of the buckle 281, completing the fixation. This allows for quick replacement of the grinding head and improves testing efficiency.

[0033] A specific application of this embodiment is as follows: In use, the product to be tested is first placed between the two main clamping blocks 23. Then, motor 213 is started, driving the threaded rod 211 to rotate. Due to the two opposite-direction threads on the threaded rod 211, the slider 22 causes the two main clamping blocks 23 to move closer together to clamp the product. Simultaneously, the auxiliary clamping block 231 slides inside the main clamping block 23, conforming to different product shapes. The anti-slip pad 232 provides better fixation. The limiting block 234 slides on the inner wall of the limiting groove 233, preventing the auxiliary clamping block 231 from detaching from the main clamping block 23. While the main clamping block 23 moves, the slider 22, located on the front, slides on the outer surface of the sliding rod 212, providing a stable movement trajectory for the main clamping block 23. Then, the electric telescopic rod 24 is started, causing the grinding head 29 to contact the product surface for grinding testing. Finally, motor 253 is started, driving the turntable 251 to rotate. The rotating rod 252 and the internal groove of the slide plate 254 are slidably connected, causing the two sides of the slide plate 254 to slide inside the limit block 255, thereby making the slide plate 254 reciprocate left and right, and polishing the product in multiple directions. Then, the motor 113 is started, which causes the gear 212 to drive the gear 111 to rotate, thereby making the turntable 11 rotate inside the operating table 1 for operation at different positions. When it is necessary to replace the grinding head 29, press the button 271 to make the latch 272 slide inside the locking block 27. At this time, the latch 272 will disengage from the outer surface of the buckle 281, thereby releasing the fixation of the buckle 28. Similarly, during installation, press the button 271 to insert the buckle 281 into the inner wall of the insertion hole 274. After releasing, the spring 273 will cause the latch 272 to reset due to the elasticity, so that the outer surface of the latch 272 contacts the outer surface of the buckle 281, and the fixation is completed.
