Description

Technical Field

[0001] This utility model relates to the field of testing machine technology, specifically to a wear-resistant testing machine with high stability. Background Technology

[0002] In many industrial sectors today, from automobile manufacturing to electronic equipment production, from aerospace component processing to the production of everyday consumer goods, the wear resistance of materials plays a crucial role. With the rapid development of science and technology, new materials such as high-performance polymers, nanocomposite materials, and high-strength alloys are constantly emerging. These materials are widely used in key components, and the need for accurate evaluation of their wear resistance characteristics is becoming increasingly urgent.

[0003] Many existing abrasion testing machines use fixed clamping structures. These clamps are usually designed for specific types and sizes of test pieces, and their clamping force is fixed during manufacturing. In actual applications, different working environments and usage conditions will subject the test pieces to different pressures. Existing technology cannot adjust the clamping force according to actual working conditions, so it cannot accurately simulate the stress conditions of the test pieces in actual use, and thus cannot obtain test results that accurately reflect the abrasion resistance performance of the test pieces. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant testing machine with high stability to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing machine body;

[0006] A transmission assembly is housed within the testing machine body. The transmission assembly includes a rubber air chamber fixedly connected to the testing machine body and a first sliding plate slidably connected to the testing machine body. A guide rod is fixedly connected to the rubber air chamber. A first damper is fixedly connected to the guide rod. A second transmission rod is fixedly connected to the first damper. A third damper is fixedly connected to the second transmission rod. A first fixed rod is fixedly connected to the first damper. A first transmission rod is slidably connected to the first fixed rod. A clamping rod is fixedly connected to the first transmission rod. The clamping rod is rotatably connected to the testing machine body. A fixed frame is slidably connected to the first sliding plate.

[0007] A first electric telescopic rod is slidably connected to the body of the testing machine. A second sliding plate is slidably connected to the first electric telescopic rod. A second electric telescopic rod is fixedly connected between the bottom of the second sliding plate and the body of the testing machine. A second transmission rod is rotatably connected to the second sliding plate. A piston is slidably connected inside the rubber air chamber. A connecting rod is fixedly connected to the piston inside the rubber air chamber.

[0008] The mounting column is placed inside the testing machine body and is slidably connected to the first sliding plate. The bottom of the mounting column is fixed to the first electric telescopic rod. An opening is provided on the second sliding plate, and the mounting column is slidably connected to the opening on the second sliding plate. The bottom of the mounting column is slidably connected to the testing machine body.

[0009] Furthermore, the clamping rod is rotatably connected to the testing machine body via a second rotating shaft, and the second transmission rod is rotatably connected to the second sliding plate via a first rotating shaft.

[0010] The above technical solution is adopted: by setting a clamping rod rotatably connected to the testing machine body, it is convenient to clamp the test piece on the testing machine body during use. When the second transmission rod is driven to move at one end, the other end is driven.

[0011] Furthermore, a cylinder is fixedly connected to the second sliding plate, and a second damping is fixedly connected between the cylinder on the testing machine body and the first sliding plate.

[0012] The above technical solution is adopted: by setting a second damper, the shock absorption capacity of the first sliding plate is improved.

[0013] Furthermore, the testing machine body has an opening, and the mounting column is slidably connected to the opening on the testing machine body.

[0014] The above technical solution is adopted: by opening a hole in the body of the testing machine, it is convenient for the installation column to slide in it during use.

[0015] Furthermore, a second fixed rod is fixedly connected to the first fixed rod, and the second fixed rod is slidably connected to the first transmission rod.

[0016] The above technical solution involves a second fixed rod. When the second fixed rod contacts the first transmission rod, it can drive the first transmission rod to rotate.

[0017] Furthermore, an opening is provided on the side of the testing machine body near the rubber air chamber, and the connecting rod is slidably connected in the opening on the testing machine body near the rubber air chamber.

[0018] The above technical solution is adopted: by opening a hole in the body of the testing machine, the connecting rod is prevented from blocking the first sliding plate.

[0019] Furthermore, a slot is provided on the side of the testing machine body near the first electric telescopic rod, and a snap-fit ​​plate is fixedly connected to the first electric telescopic rod. The snap-fit ​​plate on the first electric telescopic rod is slidably connected to the slot in the inner wall of the testing machine body.

[0020] The above technical solution is adopted: by opening a slot in the body of the testing machine, the position of the electric telescopic rod is limited during use to prevent the electric telescopic rod from falling off.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, when the first electric telescopic rod slides, it drives the second transmission rod to compress, causing it to rotate on the second sliding plate. The rotation of the second transmission rod causes the first damper to slide on the guide rod away from the rubber air chamber. The first damper then drives the first fixed rod to move. The first fixed rod drives the first transmission rod to rotate through the second fixed rod. The first transmission rod ultimately drives the clamping rod to rotate, achieving tight compression of the test piece. The clamping force can be flexibly changed according to the sliding condition of the first electric telescopic rod, because the sliding displacement of the first electric telescopic rod can be adjusted according to actual testing needs. This drives a series of subsequent transmission components to move, thereby achieving adjustment of the clamping force and solving the problem in the prior art that the clamping force on the test piece cannot be adjusted.

[0033] 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 protection scope of the present utility model.

[0034] Example:

[0035] like Figures 1-4 As shown, this utility model provides a technical solution: a testing machine body 1;

[0036] Transmission assembly 2 is placed inside the testing machine body 1. Transmission assembly 2 includes a rubber air chamber 22 fixedly connected to the testing machine body 1 and a first sliding plate 21 slidably connected to the testing machine body 1. A guide rod 23 is fixedly connected to the rubber air chamber 22. A first damper 24 is fixedly connected to the guide rod 23. A second transmission rod 28 is fixedly connected to the first damper 24. A third damper 212 is fixedly connected to the second transmission rod 28. A first fixed rod 25 is fixedly connected to the first damper 24. A first transmission rod 27 is slidably connected to the first fixed rod 25. A clamping rod 210 is fixedly connected to the first transmission rod 27. The clamping rod 210 is rotatably connected to the testing machine body 1. A fixed frame 33 is slidably connected to the first sliding plate 21.

[0037] The first electric telescopic rod 3 is slidably connected inside the testing machine body 1. The first electric telescopic rod 3 is slidably connected to the second sliding plate 34. The bottom of the second sliding plate 34 is fixedly connected to the testing machine body 1. The second transmission rod 28 is rotatably connected to the second sliding plate 34. A piston is slidably connected inside the rubber air chamber 22. A connecting rod 35 is fixedly connected to the piston inside the rubber air chamber 22.

[0038] Mounting column 4 is placed inside the testing machine body 1. Mounting column 4 is slidably connected to the first sliding plate 21. The bottom of mounting column 4 is fixed to the first electric telescopic rod 3. An opening is provided on the second sliding plate 34. Mounting column 4 is slidably connected to the opening on the second sliding plate 34. The bottom of mounting column 4 is slidably connected to the testing machine body 1.

[0039] In this invention, when the first electric telescopic rod 3 slides, it drives the second transmission rod 28 to press, causing it to rotate on the second sliding plate 34. The rotation of the second transmission rod 28 drives the first damper 24 to slide on the guide rod 23 away from the rubber air chamber 22. The first damper 24 then drives the first fixed rod 25 to move. The first fixed rod 25 drives the first transmission rod 27 to rotate through the second fixed rod 26. The first transmission rod 27 ultimately drives the clamping rod 210 to rotate, achieving tight pressing of the test piece. The clamping force can be flexibly changed according to the sliding condition of the first electric telescopic rod 3, because the sliding displacement of the first electric telescopic rod 3 can be adjusted according to the actual testing requirements, thereby driving the subsequent series of transmission components to move, achieving precise adjustment of the clamping force, and solving the problem in the prior art that the clamping force of the test piece cannot be adjusted.

[0040] Furthermore, such as Figures 1 to 5 As shown, the clamping rod 210 is rotatably connected to the testing machine body 1 via the second rotating shaft 211, and the second transmission rod 28 is rotatably connected to the second sliding plate 34 via the first rotating shaft 29. By setting the clamping rod 210 to be rotatably connected to the testing machine body 1, it is convenient to clamp the workpiece to be tested on the testing machine body 1. When one end of the second transmission rod 28 is driven to move, the other end is driven.

[0041] A cylinder is fixedly connected to the second sliding plate 34. A second damper 32 is fixedly connected between the cylinder on the test machine body 1 and the first sliding plate 21. By setting the second damper 32, the shock absorption capacity of the first sliding plate 21 is improved.

[0042] The testing machine body 1 has an opening, and the mounting column 4 is slidably connected in the opening on the testing machine body 1. By having an opening on the testing machine body 1, it is easy for the mounting column 4 to slide in it during use.

[0043] A second fixed rod 26 is fixedly connected to the first fixed rod 25. The second fixed rod 26 is slidably connected to the first transmission rod 27. By providing the second fixed rod 26, when the second fixed rod 26 contacts the first transmission rod 27, it can drive the first transmission rod 27 to rotate.

[0044] An opening is provided on the side of the testing machine body 1 near the rubber air chamber 22. The connecting rod 35 is slidably connected in the opening on the testing machine body 1 near the rubber air chamber 22. By providing an opening on the testing machine body 1, the connecting rod 35 is prevented from being pressed against and causing it to jam the first sliding plate 21.

[0045] The above solution also has the problem of not limiting the first electric telescopic rod 3, such as... Figure 5As shown, a slot is provided on the side of the testing machine body 1 near the first electric telescopic rod 3. A snap-fit ​​plate is fixedly connected to the first electric telescopic rod 3. The snap-fit ​​plate on the first electric telescopic rod 3 is slidably connected in the slot on the inner wall of the testing machine body 1. By providing a slot in the testing machine body 1, the position of the electric telescopic rod is limited during use to prevent the electric telescopic rod from falling off.

[0046] Working principle: such as Figures 1-5 As shown, when using it, first place the test piece in the fixed frame 33, tighten the bolts on the fixed frame 33 to achieve initial fixation, and fix the roller on the mounting column 4;

[0047] Activate the second electric telescopic rod 31, which raises the second sliding plate 34. The second sliding plate 34 compresses the second damper 32 through the cylinder, which in turn causes the first sliding plate 21 to rise, so that the detection piece is raised and pressed against the roller. Activate the first electric telescopic rod 3, which causes the first electric telescopic rod 3 to move the mounting column 4, which in turn causes the roller on the mounting column 4 to slide on the detection piece.

[0048] When the first electric telescopic rod 3 slides, it compresses the third damper 212, which in turn drives the second transmission rod 28 to compress the first damper 24. This causes the second transmission rod 28 to rotate on the second sliding plate 34, which in turn drives the first damper 24 to slide on the guide rod 23 away from the rubber air chamber 22. This causes the first transmission rod 27 to gradually press against the first transmission rod 28. The first transmission rod 28 drives the clamping rod 210 to rotate, which in turn causes the clamping rod 210 to tightly press the test piece. This ensures that the test piece does not shift when the test equipment detects test data as the roller slides on the test piece.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
