Technical Field
[0001] This utility model relates to the field of sealing ring performance testing technology, and more specifically, to a high-strength, high-wear-resistant sealing ring performance testing device. Background Technology
[0002] A sealing ring is a mechanical component used to prevent fluid leakage. It is usually installed in the gap between the rotating shaft and the stationary part of mechanical equipment. Through its own elastic deformation and tight fit with the sealing surface, it can effectively prevent fluid leakage inside the equipment, thereby ensuring the normal operation of the mechanical equipment and improving its working efficiency, safety and reliability. It is widely used in various industrial equipment such as automobile engines, compressors, and pumps. The strength and wear resistance of sealing rings are mainly tested using the Rockwell hardness test.

The placement frame has an open movable cavity, and limiting arcs are provided on both sides of the movable cavity. A locking frame is fixedly connected to the outer side of the limiting arcs.
[0004] Although the aforementioned patent, through its movable cavity, locking frame, limiting arc, placement frame, fixing plate, fixing rod, driven bevel gear, screw block, rotating handle, rotating rod, driving bevel gear, pull screw, and moving plate, enables the device to achieve convenient fixing and adjustment, solving the problem that existing sealing ring performance testing devices on the market lack convenient fixing and adjustment functions, and that sealing rings of varying sizes cannot be flexibly positioned during testing, resulting in inconsistent testing positions and affecting testing accuracy and data processing, the following shortcomings still exist in its use: 1. The device requires alternating adjustments and fixing of the locking box position, which is cumbersome, prolongs the overall working time, reduces testing efficiency, and easily causes worker fatigue during prolonged operation; 2. The limiting arc of the device cannot be quickly disassembled, making subsequent replacement and maintenance inconvenient.
[0005] Therefore, there is an urgent need for a high-strength, high-wear-resistant sealing ring performance testing device to solve the above problems. Utility Model Content

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] A high-strength, high-wear-resistant sealing ring performance testing device includes a working plate, a placement frame fixedly connected to the top wall of the working plate, and further includes:
[0009] The linkage drive assembly includes positioning blocks symmetrically rotatably connected to the outer wall of the placement frame.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0028] like Figure 1-6 As shown, the high-strength, high-wear-resistant sealing ring performance testing device proposed in this embodiment includes a working plate 1, a placement frame 7 fixedly connected to the top wall of the working plate 1, and further includes:
[0029] The linkage drive assembly includes a positioning block 8 symmetrically rotatably connected to the outer wall of the placement frame 7. A handle 9 is fixedly connected to the outer wall of the right positioning block 8. A cross drive rod 10 is fixedly connected between the symmetrical positioning blocks 8. A symmetrically distributed drive gear 12 is slidably connected to the outer wall of the cross drive rod 10. A locking box 11 is rotatably connected to the outer wall of the drive gear 12. A driven gear 13 is rotatably connected to the inner wall of the locking box 11, and the outer wall of the driven gear 13 meshes with the outer wall of the drive gear 12. A drive bevel gear 14 is fixedly connected to the outer wall of the drive gear 12. Rotating the handle 9 causes the right positioning block 8 to rotate, which in turn causes the cross drive rod 10 to rotate. When the cross drive rod 10 rotates, the drive gear 12 slides on its outer wall. Since the drive gear 12 is rotatably connected to the locking box 11, the drive gear 12 rotates, and the rotation of the drive gear 12 causes the driven gear 13 that meshes with it to rotate.
[0030] The easy-to-disassemble components are located on the inner wall of the locking box 11.
[0031] like Figure 6As shown, in a preferred embodiment, based on the above method, the disassembly assembly further includes a limiting block 22 slidably connected to the inner wall of the locking box 11. A lever 23 is fixedly connected to the top wall of the limiting block 22, and the lever 23 is slidably connected to the locking box 11. Symmetrically distributed strong springs 21 are fixedly connected to the outer wall of the limiting block 22, and the end of the strong spring 21 away from the limiting block 22 is fixedly connected to the locking box 11. Symmetrically distributed connecting frames 20 are slidably connected to the outer wall of the limiting block 22, and the connecting frames 20 are slidably connected to the locking box 11. A limiting arc 24 is fixedly connected to the outer wall of the connecting frame 20. When it is necessary to disassemble the limiting arc... At 24:00, move the lever 23. The lever 23 moves the limit block 22 and compresses the strong spring 21. At this time, the limit block 22 moves out of the connecting frame 20, thereby releasing the limit on the limit block 22. At this time, the connecting frame 20 and the limiting arc 24 can be removed from the locking box 11. During installation, insert the connecting frame 20 into the locking box 11. The connecting frame 20 automatically squeezes the limit block 22 and compresses the strong spring 21. When the limit block 22 corresponds to the limiting groove on the connecting frame 20 (not shown in the figure), the strong spring 21 rebounds, causing the limit block 22 to be locked into the connecting frame 20 to achieve the limit, thereby fixing the limiting arc 24 on the locking box 11.
[0032] like Figure 5 As shown, in a preferred embodiment, based on the above method, a bidirectional screw 16 is rotatably connected to the inner wall of the locking box 11, a driven bevel gear 15 is fixedly connected to the outer wall of the bidirectional screw 16, and the outer wall of the driven bevel gear 15 meshes with the outer wall of the driving bevel gear 14. Symmetrically distributed screw blocks 17 are threadedly connected to the outer wall of the bidirectional screw 16, and the screw blocks 17 are slidably connected to the locking box 11. A fixing rod 18 is fixedly connected to the outer wall of the screw blocks 17, and the fixing rod 18 is slidably connected to the locking box 11. The end of the fixing rod 18 away from the screw blocks 17 is fixedly connected to... There is a fixed plate 19, and the outer wall of the fixed plate 19 abuts against the inner wall of the placement frame 7. The drive bevel gear 14 on the drive gear 12 rotates, and the drive bevel gear 14 drives the driven bevel gear 15 that meshes with it to rotate, thereby causing the bidirectional screw 16 to rotate. When the bidirectional screw 16 rotates, the symmetrical screw blocks 17 on its outer wall move closer or further apart under the action of the threads. The screw blocks 17 drive the fixed rod 18 and the fixed plate 19 to move, thereby fixing or loosening the sealing ring inside the placement frame 7. Moreover, multiple locking boxes 11 can be adjusted simultaneously by operating a handle 9 without the need for alternating operation.
[0033] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer wall of the working plate 1 is further provided with symmetrically distributed support legs 2, and the outer wall of the support legs 2 is provided with support plates 3. The equipment is supported and fixed by the support legs 2 and the support plates 3.
[0034] like Figure 1As shown, in a preferred embodiment, based on the above method, a working frame 4 is fixedly connected to the top wall of the working plate 1, a hydraulic cylinder 5 is fixedly connected to the outer wall of the working frame 4, and a detection probe 6 is fixedly connected to the output end of the hydraulic cylinder 5. The sealing ring is tested by Rockwell hardness test through the hydraulic cylinder 5 and the detection probe 6.
[0035] Specifically, when using this high-strength, high-wear-resistant sealing ring performance testing device: First, place the sealing ring to be tested on the limiting arc 24 and adjust the position of the locking box 11. Then, turn the handle 9 to drive the right positioning block 8 to rotate, which in turn causes the cross drive rod 10 to rotate. When the cross drive rod 10 rotates, the drive gear 12 slides on its outer wall. Since the drive gear 12 is rotatably connected to the locking box 11, the drive gear 12 rotates, which drives the driven gear 13 that meshes with it to rotate. At the same time, the drive bevel gear 14 on the drive gear 12 rotates, which drives the driven bevel gear 15 that meshes with it to rotate, thereby causing the bidirectional screw 16 to rotate. When the bidirectional screw 16 rotates, the symmetrical screw blocks 17 on its outer wall move closer or further apart under the action of the threads. The screw blocks 17 drive the fixed rod 18 and the fixed plate 19 to move, thereby achieving sealing within the placement frame 7. The ring can be fixed or loosened by a single handle 9, allowing simultaneous adjustment of multiple locking boxes 11 without the need for alternating operation. When the limiting arc 24 needs to be disassembled, the lever 23 is moved, causing the limiting block 22 to move and compress the strong spring 21. At this time, the limiting block 22 moves out of the connecting frame 20, thus releasing the limiting of the limiting block 22. The connecting frame 20 and the limiting arc 24 can then be removed from the locking box 11. During installation, the connecting frame 20 is inserted into the locking box 11. The connecting frame 20 automatically squeezes the limiting block 22 and compresses the strong spring 21. When the limiting block 22 aligns with the limiting groove (not shown in the figure) on the connecting frame 20, the strong spring 21 rebounds, causing the limiting block 22 to snap into the connecting frame 20 to achieve the limiting, thereby fixing the limiting arc 24 on the locking box 11. Afterward, the sealing ring can be tested using the Rockwell hardness test by the hydraulic cylinder 5 and the testing probe 6.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
