Description

Technical Field

[0001] This utility model relates to the field of wear resistance testing devices, and more specifically, to a wear resistance testing device for a groove needle outer surface coating. Background Technology

[0002] Abrasion resistance testing simulates the wear process under actual usage conditions. By measuring the performance changes of materials or products during wear, its durability is assessed. Abrasion resistance testing allows for the prediction of material wear patterns, enabling appropriate measures to be taken to extend material lifespan and reduce maintenance and replacement costs. Abrasion resistance testing is a crucial means of product quality supervision and inspection, used to verify whether products meet relevant standards and requirements, ensuring product quality and reliability in the market. After production, groove pins require abrasion resistance testing of their surface coating.

[0003] Existing wear resistance testing devices produce powder and debris on the testing table due to continuous friction over a long period of time. However, the testing table is equipped with a mechanism to fix the workpiece, making it inconvenient to clean the testing table. Therefore, we have made an improvement and proposed a wear resistance testing device for the outer surface coating of grooved pins. Utility Model Content

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0005] A wear resistance testing device for the outer surface coating of grooved needles is proposed to improve the above-mentioned problems.

[0006] The present invention is as follows:

[0007] The device includes a coating abrasion tester body, comprising a main body, a protective cover, and a grinding head. A guide rail is fixedly installed at the bottom of the main body, and a test platform is slidably connected to the guide rail. An extension plate is integrally formed on the side wall of the test platform, and a locking mechanism is provided on the extension plate. A connecting protrusion is fixedly installed on the top of the test platform, and a connecting seat is sleeved on the top of the connecting protrusion. A threaded rod is rotatably connected to the top of the connecting seat, and a driving mechanism is provided on the top of the threaded rod. A mounting plate is threadedly connected to the threaded rod, and a connecting plate is fixedly installed on the side wall of the mounting plate. An L-shaped clamping plate is integrally formed on the connecting plate, and a guiding mechanism is provided on the top of the connecting seat.

[0008] As a preferred technical solution of this utility model, a guide groove is provided on the guide rail, and a slide rail is fixedly installed at the bottom of the test platform, the slide rail matching the guide groove.

[0009] As a preferred technical solution of this utility model, the locking mechanism includes a first hand-tightening bolt disposed on the extension plate.

[0010] As a preferred technical solution of this utility model, the side wall of the connecting seat is threaded with a second hand-tightening bolt.

[0011] As a preferred technical solution of this utility model, the driving mechanism includes a handwheel fixedly installed on the top of the threaded rod.

[0012] As a preferred technical solution of this utility model, the bottom of the connecting seat is provided with a connecting groove, which matches the connecting protrusion.

[0013] As a preferred technical solution of this utility model, the guide mechanism includes a slide rod fixedly installed on the top of the connecting seat, and the mounting plate is slidably connected to the slide rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] 1. By first removing the second hand-tightening bolt, and then pulling the connecting seat upwards, the connecting protrusion on the test platform separates from the connecting groove at the bottom of the connecting seat. Next, remove the first hand-tightening bolt, and then pull the test platform. The test platform drives the slide rail to slide in the guide groove, thus removing the test platform. After removal, only two connecting protrusions remain on the test platform, making it easy to clean. This not only allows for the removal and cleaning of the test platform, but also the removal of the workpiece fixing mechanism on the test platform, making cleaning even more convenient. It is very convenient to use and solves the problem in the existing technology where powder and debris fall onto the test platform due to continuous friction over a long period of time, but the test platform has a workpiece fixing mechanism, making it inconvenient to clean.

The coating wear meter body 1 includes a body 101, a protective cover 102, and a grinding head 103. A guide rail 2 is fixedly installed at the bottom of the body 101, and a test platform 3 is slidably connected to the guide rail 2. An extension plate 4 is integrally formed on the side wall of the test platform 3, and a locking mechanism is provided on the extension plate 4 for fixing the test platform 3. A connecting protrusion 5 is fixedly installed on the top of the test platform 3 for connecting with a connecting seat 6. Next, a connecting seat 6 is fitted on the top of the connecting protrusion 5. A threaded rod 7 is rotatably connected to the top of the connecting seat 6. A driving mechanism is provided on the top of the threaded rod 7. The driving mechanism drives the threaded rod 7 to rotate. An mounting plate 8 is threadedly connected to the threaded rod 7. The rotation of the threaded rod 7 causes the mounting plate 8 to move. A connecting plate 9 is fixedly installed on the side wall of the mounting plate 8. The movement of the mounting plate 8 causes the connecting plate 9 to move. An L-shaped clamping plate 10 is integrally formed on the connecting plate 9. The movement of the connecting plate 9 causes the L-shaped clamping plate 10 to move. A guide mechanism is provided on the top of the connecting seat 6.

[0032] A guide groove 11 is provided on the guide rail 2, and a slide rail 12 is fixedly installed at the bottom of the test platform 3. The test platform 3 drives the slide rail 12 to slide in the guide groove 11, and the slide rail 12 matches the guide groove 11.

[0033] The locking mechanism includes a first hand-tightening bolt 13 disposed on the extension plate 4, which is used to fix the test bench 3.

[0034] A second hand-tightening bolt 14 is threaded onto the side wall of the connecting seat 6. The second hand-tightening bolt 14 is used to fix the connecting protrusion 5 and the connecting seat 6 together.

[0035] The drive mechanism includes a handwheel 15 fixedly mounted on the top of the threaded rod 7. The rotation of the handwheel 15 drives the threaded rod 7 to rotate.

[0036] A connecting groove 16 is provided at the bottom of the connecting seat 6. The connecting groove 16 matches the connecting protrusion 5. When the test table 3 is removed for cleaning, the connecting seat 6 is pulled upward to separate the connecting protrusion 5 on the test table 3 from the connecting groove 16 at the bottom of the connecting seat 6.

[0037] The guiding mechanism includes a slide rod 17 fixedly installed on the top of the connecting seat 6. The mounting plate 8 moves along the slide rod 17 and is slidably connected to the slide rod 17.

[0039] Specifically, when using this grooved pin outer surface coating wear resistance testing device: place the grooved pin to be tested on the test table 3, then install the handwheel 15. The rotation of the handwheel 15 drives the threaded rod 7 to rotate, and the rotation of the threaded rod 7 drives the mounting plate 8 to move downward. The mounting plate 8 moves along the slide rod 17. At the same time as the mounting plate 8 moves downward, it drives the connecting plate 9 to move downward. The downward movement of the connecting plate 9 drives the L-shaped clamping plate 10 to move downward, so that the L-shaped clamping plate 10 clamps the grooved pin. Then, the wear resistance test of the grooved pin outer surface coating can be performed.

[0040] When it is necessary to clean the test bench 3, first remove the second hand-tightening bolt 14, then pull the connecting seat 6 upward to separate the connecting protrusion 5 on the test bench 3 from the connecting groove 16 at the bottom of the connecting seat 6. Next, remove the first hand-tightening bolt 13 (before removal, the first hand-tightening bolt 13 is threadedly connected to the guide rail 2), and then pull the test bench 3. The test bench 3 drives the slide rail 12 to slide in the guide groove 11, so that the test bench 3 can be removed. After removal, there are only two connecting protrusions 5 on the test bench 3, which makes it convenient to clean the test bench 3.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
