Description

Technical Field

[0001] This utility model relates to the field of material surface performance testing technology, and in particular to a wear resistance testing device for water-based UV-cured antibacterial and wear-resistant coated plates. Background Technology

[0002] Material surface performance testing refers to the process of evaluating the physical, chemical, and mechanical properties of a material surface through a series of experimental methods and equipment. The main purpose of the water-based UV-cured antibacterial wear-resistant coating board wear resistance testing device is to test the wear resistance of the coating board, which falls entirely within the scope of mechanical performance testing in material surface performance testing. By simulating various friction conditions, such as different friction speeds, pressures, and friction media, this device can accurately measure key indicators such as the wear amount and friction coefficient of the coating board during the friction process, thereby evaluating the wear resistance performance of the coating board.

[0003] In modern industry, abrasion resistance testing equipment for coated plates typically uses a gripping device controlled by a threaded rod to fix the sample. While this method can meet testing requirements to some extent, in actual operation, operators need to constantly tighten the threaded rod to ensure sample stability and test accuracy. This frequent operation not only increases the complexity of the operation but also affects the continuity and efficiency of the test to some extent. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of a relatively cumbersome operation process when fixing the coated plate. To this end, we propose a water-based UV curing antibacterial wear-resistant coating plate wear resistance testing device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a water-based UV-curable antibacterial and wear-resistant coating plate wear resistance testing device, comprising a worktable, a movable arm mounted on the top of the worktable, a connecting arm mounted on the front end of the movable arm, a grinding plate mounted on the bottom end of the connecting arm, fixed blocks fixedly connected to both sides of the worktable, two movable rails fixedly connected to the top of the worktable, movable blocks slidably connected inside the movable rails, a connecting plate fixedly connected to one side of the movable block, and an adjusting rod fixedly connected to the bottom end of the connecting plate. The adjusting rod is slidably connected to the inside of the fixed block. A handle is fixedly connected to the bottom end of the adjusting rod. A pressure plate is fixedly connected to the other side of the moving block. Sliding grooves are provided at both the front and rear ends of the fixed block. A sliding rod is slidably connected inside the sliding groove. A push-pull plate is fixedly connected to the end of the sliding rod away from the fixed block. A first elastic spring is slidably connected to the surface of the sliding rod. The end of the first elastic spring near the fixed block is fixedly connected to the fixed block. The end of the first elastic spring away from the fixed block is fixedly connected to the push-pull plate. Several limiting grooves are provided on the surface of the adjusting rod.

[0006] Preferably, a return spring is fixedly connected to the top end of the handle, and there are two return springs, with the top end of the return spring fixedly connected to the bottom end of the fixing block.

[0007] Preferably, the front and rear ends of the moving rail are provided with first sliding grooves, and the front and rear ends of the moving block are fixedly connected with first sliders, with the interior of the first sliding grooves slidably connected to the first sliders.

[0008] Preferably, a second sliding groove is provided on both sides of the sliding groove, and a second slider is fixedly connected to both sides of the sliding rod, with the interior of the second sliding groove slidably connected to the second slider.

[0009] Preferably, the surface of the sliding rod is provided with an inclined surface, and the sliding rod is used in conjunction with the limiting groove.

[0010] Preferably, the bottom end of the connecting arm has two pressing grooves, a second elastic spring is installed inside the pressing groove, one end of the second elastic spring is fixedly connected to a pressing block, the top end of the grinding plate is fixedly connected to a limiting plate, the surface of the limiting plate has two pop-out grooves, and the pressing block is used in conjunction with the pop-out grooves.

[0011] Preferably, a friction plate is installed at the bottom end of the lower pressure plate, and the friction plate is made of rubber.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when the worker needs to fix the coating plate on the workbench, the push-pull plate is pulled out to both ends to pull the sliding rod out of the limiting groove, releasing the adjusting rod from its limiting position. Then, the handle is moved to drive the adjusting rod to slide inside the fixing block, simultaneously moving the lower pressure plate synchronously. After the lower pressure plate moves to the position close to the coating plate, the push-pull plate is released, and the elastic force stored in the first elastic spring causes the sliding rod to quickly return to the limiting groove, limiting the adjusting rod and the lower pressure plate simultaneously, thus achieving convenient fixing of the coating plate when testing is required. By setting the fixing method of the coating plate to a modular design, the coating plate no longer needs to be frequently tightened with threaded rods as in the prior art when it needs to be fixed, making the fixing of the coating plate more efficient and convenient, thereby effectively improving the testing efficiency and user experience of the coating plate.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a water-based UV-curable antibacterial and wear-resistant coating board wear resistance testing device, including a worktable 1, a movable arm 2 installed at the top of the worktable 1, a connecting arm 3 installed at the front end of the movable arm 2, a grinding plate 4 installed at the bottom end of the connecting arm 3, fixed blocks 5 fixedly connected to both sides of the worktable 1, two movable rails 6 fixedly connected to the top of the worktable 1, movable blocks 7 slidably connected inside the movable rails 6, a connecting plate 8 fixedly connected to one side of the movable block 7, an adjusting rod 9 fixedly connected to the bottom end of the connecting plate 8, the adjusting rod 9 slidably connected to the inside of the fixed block 5, a handle 10 fixedly connected to the bottom end of the adjusting rod 9, a pressure plate 11 fixedly connected to the other side of the movable block 7, sliding grooves 12 are opened at both the front and rear ends inside the fixed block 5, a sliding rod 13 is slidably connected inside the sliding groove 12, a push-pull plate 14 is fixedly connected to the end of the sliding rod 13 away from the fixed block 5, a first elastic spring 15 is slidably connected to the surface of the sliding rod 13, and the first elastic spring 15 is close to the fixed block 5. One end of block 5 is fixedly connected to fixed block 5, and the end of the first elastic spring 15 away from fixed block 5 is fixedly connected to push-pull plate 14. Several limiting grooves 16 are opened on the surface of adjusting rod 9. When the operator needs to fix the coating plate on the workbench 1, the push-pull plate 14 is pulled out to both ends to pull out the sliding rod 13 from the limiting groove 16, so that the adjusting rod 9 is released from the limiting position. Then the handle 10 is moved to drive the adjusting rod 9 to slide inside the fixed block 5, and at the same time, the lower pressure plate 11 is moved synchronously. After the lower pressure plate 11 moves to the position close to the coating plate, the push-pull plate 14 is released. The elastic force stored in the first elastic spring 15 causes the sliding rod 13 to quickly return to the limiting groove 16, so that the adjusting rod 9 and the lower pressure plate 11 are simultaneously limited, thereby achieving convenient fixing of the coating plate when it needs to be tested. By setting the fixing method of the coating plate to a modular design, the coating plate does not need to be frequently screwed on the threaded rod when it needs to be fixed, thus making the fixing of the coating plate more efficient and convenient, thereby effectively improving the testing efficiency and user experience of the coating plate.

[0023] Reference Figure 3 As shown in this embodiment: a return spring 17 is fixedly connected to the top of the handle 10. There are two return springs 17. The top of the return spring 17 is fixedly connected to the bottom of the fixing block 5. By setting the return spring 17, when it is necessary to release the limit of the coating plate, the adjustment rod 9 is released from the limit. At this time, the elastic force of the return spring 17 can make the adjustment rod 9 drive the lower pressure plate 11 to quickly return to the initial position, thereby releasing the limit of the coating plate and making it convenient to take out after the coating plate test is completed.

[0024] Reference Figure 2As shown in this embodiment: the front and rear ends of the moving rail 6 are provided with first sliding grooves 18, and the front and rear ends of the moving block 7 are fixedly connected with first sliders 19. The interior of the first sliding groove 18 is slidably connected to the first slider 19. By setting the first sliding groove 18 and the first slider 19, the moving block 7 can move more stably inside the moving rail 6, and the sliding trajectory of the adjusting rod 9 will be limited, thereby effectively improving the stability of the lower pressure plate 11 when it moves and making it less prone to deviation.

[0025] Reference Figure 4 As shown in this embodiment: a second sliding groove 20 is provided on both sides of the sliding groove 12, and a second slider 21 is fixedly connected to both sides of the sliding rod 13. The interior of the second sliding groove 20 is slidably connected to the second slider 21. Through the setting of the second sliding groove 20 and the second slider 21, the sliding rod 13 can form a stable limit when it moves inside the fixed block 5, so that the sliding rod 13 will not deviate during the movement, and can be guaranteed to slide stably into the limit groove 16, ensuring the normal fixation of the adjusting rod 9.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: the surface of the sliding rod 13 is provided with an inclined surface 22. The sliding rod 13 is used in conjunction with the limiting groove 16. With the setting of the inclined surface 22, when the operator needs to adjust the position of the adjusting rod 9, the adjusting rod 9 can be pulled upward to move the sliding rod 13 out of the limiting groove 16, thereby achieving convenient adjustment when the adjusting rod 9 needs to be adjusted, thereby further improving the operating efficiency when fixing the coating plate.

[0027] Reference Figure 5 As shown in this embodiment: the bottom end of the connecting arm 3 has two pressing grooves 23, and a second elastic spring 24 is installed inside the pressing groove 23. One end of the second elastic spring 24 is fixedly connected to a pressing block 25. The top end of the grinding plate 4 is fixedly connected to a limiting plate 26. The surface of the limiting plate 26 has two pop-out grooves 27. The pressing block 25 is used in conjunction with the pop-out grooves 27. When the grinding plate 4 is damaged and needs to be replaced, the pressing block 25 is pressed inward to move the pressing block 25 into the pressing groove 23, so that the grinding plate 4 is released from the limiting position. At this time, the grinding plate 4 is removed, and the pop-out groove 27 on the surface of the new grinding plate 4 is aligned with the pressing block 25 and snapped in. After snapping in, the elastic force stored in the second elastic spring 24 makes the pressing block 25 firmly locked in the pop-out groove 27, thereby achieving the rapid replacement of the grinding plate 4 and improving the replacement efficiency when the grinding plate 4 is damaged.

[0028] Reference Figure 6As shown in this embodiment: a friction plate 28 is installed at the bottom end of the lower pressure plate 11. The friction plate 28 is made of rubber. By setting the friction plate 28, the lower pressure plate 11 can have greater friction when it contacts the coating plate, so that the coating plate will not shift, thereby effectively improving the fixing effect when fixing the coating plate.

[0029] Working principle: When the operator needs to fix the coating plate on the workbench 1, the push-pull plate 14 is pulled out to both ends, causing the sliding rod 13 to be pulled out of the limiting groove 16, releasing the limiting position of the adjusting rod 9. Then, the handle 10 is moved, causing the adjusting rod 9 to slide inside the fixing block 5, simultaneously moving the lower pressure plate 11 synchronously. After the lower pressure plate 11 moves to the position close to the coating plate, the push-pull plate 14 is released, and the elastic force stored in the first elastic spring 15 causes the sliding rod 13 to quickly return to the limiting groove 16, so that the adjusting rod 9 and the lower pressure plate 11 are simultaneously limited, thus achieving convenient fixing of the coating plate when testing is required. By setting the fixing method of the coating plate to a modular design, the coating plate can be... Unlike existing technologies, this design eliminates the need for frequent screwing of threaded rods when fixing the coating plate, making the fixing process more efficient and convenient. This significantly improves the testing efficiency and user experience of the coating plate. The return spring 17 allows the adjusting rod 9 to be released from its limit when the coating plate needs to be unblocked. The spring force of the return spring 17 then causes the adjusting rod 9 to quickly return the lower pressure plate 11 to its initial position, thus releasing the coating plate from its limit and facilitating easy removal after testing. The first groove 18 and the first slider 19 ensure more stable movement of the moving block 7 within the moving rail 6 and limit the sliding trajectory of the adjusting rod 9, thereby effectively... To improve the stability of the lower pressure plate 11 during movement and prevent deviation, the second sliding groove 20 and the second slider 21 are designed to provide a stable limit for the sliding rod 13 when it moves inside the fixed block 5. This prevents the sliding rod 13 from deviating during movement and ensures that it slides securely into the limiting groove 16, thus ensuring the proper fixation of the adjusting rod 9. The inclined surface 22 allows for easy adjustment of the adjusting rod 9 by pulling it upwards, thus moving the sliding rod 13 out of the limiting groove 16. This further improves the operational efficiency of fixing the coating plate. When the grinding plate 4 is damaged and needs adjustment... When replacement is required, press the pressing block 25 inward to move it into the pressing groove 23, thereby releasing the limiting position of the grinding plate 4. Then, remove the grinding plate 4 and align the pop-out groove 27 on the surface of the new grinding plate 4 with the pressing block 25 and snap it in. After snapping in, the elastic force stored in the second spring 24 makes the pressing block 25 securely locked in the pop-out groove 27, thus achieving rapid replacement of the grinding plate 4 and improving the replacement efficiency when the grinding plate 4 is damaged. Through the setting of the friction plate 28, the lower pressure plate 11 can have greater friction when it contacts the coating plate, thereby preventing the coating plate from shifting and effectively improving the fixing effect when fixing the coating plate.
