Description

Technical Field

[0001] This utility model relates to the field of chain durability testing technology, and in particular to a short-pitch chain durability testing device. Background Technology

[0002] Short-pitch chains are precision transmission components with a smaller pitch than conventional roller chains. They feature high precision, high speed adaptability, and excellent load capacity, and are widely used in mechanical transmission and conveying systems. Short-pitch chains consist of inner chain plates, outer chain plates, pins, bushings, and rollers. The smaller pitch significantly improves transmission accuracy and meshing smoothness.

[0003] Durability testing is a critical testing method for evaluating the ability of products or materials to maintain their function and integrity under long-term use, repeated loading, or harsh environmental conditions. It is widely used in industries such as automotive, aerospace, electronics, and construction to ensure product lifespan and reliability. Durability testing equipment is typically used to perform durability tests on short-pitch chains.

[0004] When testing chains using a durability testing device, the chain is usually run through three sets of sprockets. However, these three sets of sprockets are usually fixed, which means that different sprockets cannot be replaced according to the specific chain. This is not conducive to conducting durability tests on chains of different sizes, and it also hinders the use of the durability testing device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a short-pitch chain durability performance testing device, which solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A short-pitch chain durability testing device includes a workbench. A first movable plate is mounted on one side of the workbench via an adjustment mechanism. A mounting plate is mounted on the top of the first movable plate via a rotation mechanism. A first connecting rod is mounted on the top of the mounting plate via a first positioning mechanism. A first sprocket is fixedly mounted at one end of the first connecting rod. A slot is formed inside the mounting plate. A first mounting post is mounted on the inner wall of the slot via a reset mechanism. A mounting block is fixedly mounted on the top of the workbench. A second connecting rod is mounted on the top of the mounting block via a second positioning mechanism. A second sprocket is fixedly mounted at one end of the second connecting rod. A second mounting post is mounted on the top of the workbench via a movable mechanism.

[0008] Preferably, the rotating mechanism includes a second drive motor fixedly installed on the top of the first movable plate, and a rotating rod is fixedly installed on the output end of the second drive motor. One end of the rotating rod is fixedly installed to the bottom of the mounting plate.

[0010] Preferably, the reset mechanism includes a sliding column slidably mounted on the inner wall of the slot, a sliding plate fixedly mounted on one end of the sliding column, a spring fixedly mounted on the inner wall of the slot, one end of the spring and one side of the sliding plate being fixedly mounted, and one side of the sliding plate and one end of the first mounting column being fixedly mounted.

[0011] Preferably, the second positioning mechanism includes a second positioning groove formed on the top of the mounting block, a second positioning block slidably mounted on the inner wall of the second positioning groove, a second mounting groove formed on one side of the second positioning block, the top of the second positioning block and one end of the second connecting rod being rotatably mounted, and the number of mounting blocks being two sets and symmetrically arranged.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This short-pitch chain durability performance testing device drives the first sprocket to rotate through a rotating mechanism, which in turn drives the chain through the first and second sprockets. The position of the first sprocket can be adjusted by moving it through an adjusting mechanism, allowing for adjustment of the chain tension. After the test, the chain can be removed. The first mounting post is moved away from the inner wall of the first mounting groove by a reset mechanism, thus releasing the limiting installation of the first sprocket. A suitable first sprocket can be positioned by a first positioning mechanism. The first mounting post is inserted into the inner wall of the first mounting groove by a reset mechanism, thus limiting the installation of the first sprocket.

A suitable second sprocket can be positioned by a second positioning mechanism. The second mounting post is inserted into the inner wall of the second mounting groove by a moving mechanism, thus limiting the installation of the second sprocket. This facilitates the replacement of the first and second sprockets, allowing for the replacement of appropriate first and second sprockets according to different chain sizes.

A sliding plate 17 is fixedly installed at one end of the sliding post 15. A spring 16 is fixedly installed on the inner wall of the slot 14. One end of the spring 16 is fixedly installed to one side of the sliding plate 17, and one side of the sliding plate 17 is fixedly installed to one end of the first mounting post 18, facilitating the reset movement of the first mounting post 18. A mounting block 19 is fixedly installed on the top of the platform 1. A second connecting rod 23 is installed on the top of the mounting block 19 through a second positioning mechanism. The second positioning mechanism includes a second positioning groove 20 opened on the top of the mounting block 19. A second positioning block 21 is slidably installed on the inner wall of the second positioning groove 20. A second mounting groove 22 is opened on one side of the second positioning block 21.

[0020] In use: When using this short-pitch chain durability testing device, the chain is mounted on the surface of the first sprocket 13 and the surfaces of the two sets of second sprockets 24. The second drive motor 6 drives the rotating rod 7 to rotate, which in turn drives the mounting plate 8 to rotate. The mounting plate 8 then drives the first sprocket 13 to rotate, thus enabling the chain to run via the first sprocket 13 and the second sprockets 24, allowing for durability testing. The first drive motor 2 drives the first lead screw 3 to rotate, which in turn drives the moving block 4 to move. The moving block 4 then drives the first moving plate 5 to move, which in turn drives the first sprocket 13 to move, allowing adjustment of the position of the first sprocket 13 and thus the chain tension. After the test, the chain can be removed. Pulling the sliding column 15 moves the sliding plate 17, which in turn moves the first mounting column 18 away from the inner wall of the first mounting groove 11, thus releasing the limiting installation of the first sprocket 13. Then, a suitable... The first positioning block 10 at the bottom of the first sprocket 13 is inserted into the inner wall of the first positioning groove 9 for positioning. The spring 16 resets and drives the slide plate 17 to move. The slide plate 17 drives the first mounting post 18 to insert into the inner wall of the first mounting groove 11, thus limiting the installation of the first sprocket 13. The dual-axis motor 25 drives the second lead screw 26 to rotate. The second lead screw 26 drives the second moving plate 27 to move. The second moving plate 27 drives the second mounting post 28 to leave the inner wall of the second mounting groove 22, thus releasing the limiting installation of the second sprocket 24. Then, the second positioning block 21 at the bottom of the appropriate second sprocket 24 is inserted into the inner wall of the second positioning groove 20 for positioning. The dual-axis motor 25 drives the second mounting post 28 to insert into the inner wall of the second mounting groove 22, thus limiting the installation of the second sprocket 24. This achieves the purpose of facilitating the replacement of the first sprocket 13 and the second sprocket 24, so that the appropriate first sprocket 13 and the second sprocket 24 can be replaced according to the chain of different sizes.
