Description

Technical Field

[0001] The utility model relates to the field of engineering technology, in particular to a special hardness testing device for the outer tube of a motorcycle shock absorber. Background Art

[0002] A special hardness testing device for the outer tube of a motorcycle shock absorber is a device used to measure the hardness of the outer tube of a motorcycle shock absorber. During the manufacturing process of a motorcycle shock absorber, the hardness of the outer tube is an important quality index. Such a tester usually uses a specific method or device to apply force or pressure to the surface of the shock absorber outer tube, and then measures its deformation or reaction force to determine the hardness of the outer tube. This process can help manufacturers ensure that the shock absorber outer tube meets the designed hardness standard, so as to improve the durability, performance and safety of the product.

[0003] In the prior art, most hardness testing devices usually perform hardness testing on the outer tube of the shock absorber through a structure in which a handle drives a pressing plate to rotate. In this process, it is necessary to press the handle and apply force, and it is impossible to achieve the effect of automatically pressing down to apply pressure. At the same time, it is also impossible to clamp the outer tube of the shock absorber, resulting in the position deviation of the outer tube of the shock absorber during the testing process.

[0004] For the structure of the prior art, although the structure of combining the handle and the pressing plate to perform hardness testing on the outer tube of the shock absorber can achieve the testing effect, a great deal of effort is required to press the handle during the testing process, resulting in inconvenient operation and unable to achieve the effect of automatic testing. At the same time, the inability to clamp the outer tube of the shock absorber will cause the position deviation of the outer tube of the shock absorber during the testing process, affecting the testing effect. Summary of the Utility Model

[0023] Refer to Figure 1 and Figure 2, an embodiment provided by the utility model: a special hardness testing device for the outer tube of a motorcycle shock absorber, including a testing table 1, on the upper surface of the testing table 1 is fixedly connected with a placement table 2, on the upper surface of the placement table 2 is fixedly connected with a support seat 3, the support seat 3 is arranged at both ends of the upper surface of the placement table 2, on the outer wall of the placement table 2 is fixedly connected with a motor 1 4, the output end of the motor 1 4 is fixedly connected with a gear 5, the gear 5 is rotatably connected inside the placement table 2, inside the placement table 2 is slidably connected with a rack plate 6, the rack plate 6 is meshed with the gear 5, on the outer wall of the rack plate 6 is rotatably connected with a connecting block 7, on the upper surface of the placement table 2 is fixedly connected with a support plate 8, on the outer wall of the support plate 8 is fixedly connected with a concave block 10, the concave block 10 is rotatably connected on the outer wall of the connecting block 7, inside the support plate 8 is provided with a clamping assembly for clamping the shock absorber, the clamping assembly includes a clamping rod 9, the clamping rod 9 is slidably connected inside the support plate 8, the clamping rod 9 is rotatably connected inside the connecting block 7, on the outer wall of the clamping rod 9 is fixedly connected with a limiting plate 11, on the outer wall of the clamping rod 9 is sleeved with a spring 12, one end of the spring 12 is fixedly connected to the outer wall of the limiting plate 11, and the other end of the spring 12 is fixedly connected to the inside of the support plate 8;

[0024] Specifically, first place the outer tube of the shock absorber inside the two support seats 3, start the motor 1 4 to drive the gear 5 to rotate. During the rotation of the gear 5, it drives the two rack plates 6 to slide inside the placement table 2. During the sliding of the rack plates 6, they respectively drive the two connecting blocks 7 to rotate by an angle. The rotation of the two connecting blocks 7 respectively drives the two clamping rods 9 to slide inside the support plate 8. During the sliding of the clamping rods 9, they drive the limiting plates 11 to slide and compress the springs 12. The combined action of the limiting plates 11 and the springs 12 can achieve the effect of assisting in resetting and loosening the clamping. The two clamping rods 9 slide and approach each other to squeeze against the outer wall of the shock absorber outer tube to achieve the effect of clamping and fixing, thereby preventing the shock absorber from shifting in position during the hardness testing process.

[0025] Refer to Figure 1 and Figure 3 , on the upper surface of the testing table 1 is fixedly connected with a support column 13, the support column 13 is arranged at both ends of the upper surface of the testing table 1, on the outer wall of the support column 13 is fixedly connected with a motor 2 14, the output end of the motor 2 14 is fixedly connected with a driving wheel 15, inside the support column 13 is rotatably connected with a connecting shaft 17, on the outer wall of the connecting shaft 17 is fixedly connected with a driven wheel 16, the driven wheel 16 is meshed with the driving wheel 15, on the outer wall of the connecting shaft 17 is fixedly connected with a rotating rod 18, on the outer wall of the rotating rod 18 is rotatably connected with a connecting rod 19, and inside the connecting rod 19 is fixedly connected with a pin 20;

[0026] Specifically, the starting motor two 14 drives the driving wheel 15 to rotate. The rotation of the driving wheel 15 drives the driven wheel 16 to rotate. While the driven wheel 16 rotates, it drives the connecting shaft 17 to rotate. The rotation of the connecting shaft 17 drives the rotating rods 18 at both ends to rotate by an angle. The angular rotation of the rotating rods 18 drives the connecting rods 19 to rotate by an angle respectively and drives the shaft pin 20 to slide inside the chute 23.

[0027] Refer to Figure 1 and Figure 3 , a connecting plate 21 is fixedly connected to the outer wall of the shaft pin 20. A sliding shaft 22 is fixedly connected to the inside of the connecting plate 21. A chute 23 is opened in the inside of the support column 13. The shaft pin 20 is slidably connected inside the chute 23. The sliding shaft 22 is slidably connected inside the chute 23. A top plate 24 is fixedly connected to the outer wall of the connecting plate 21. A telescopic rod 25 is fixedly connected to the lower surface of the top plate 24. The output end of the telescopic rod 25 is fixedly connected to a pressing plate 26. A detector 27 is fixedly connected to the upper surface of the pressing plate 26;

[0028] Specifically, while the shaft pin 20 slides, it also drives the connecting plate 21 to slide. During the sliding process of the connecting plate 21, it drives the sliding shaft 22 to slide along the shape of the chute 23, so that the connecting plate 21 flips by an angle during the sliding process. Furthermore, the angular flips of the two connecting plates 21 drive the top plate 24 to flip by an angle. At the same time, the top plate 24 drives the two telescopic rods 25 and the pressing plate 26 to flip and be placed above the shock absorber outer tube. Start the two telescopic rods 25 to drive the pressing plate 26 to move downward to apply pressure to the shock absorber outer tube for hardness testing. The test data is displayed through the detector 27, thus achieving the effect of automatically applying pressure for hardness testing.

[0029] Working principle: When a hardness test needs to be performed on the outer tube of the shock absorber, first start the second motor 14 to drive the driving wheel 15 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate and drives the connecting shaft 17 to rotate. The rotation of the connecting shaft 17 drives the two rotating rods 18 to rotate by an angle. The rotation of the rotating rods 18 by an angle drives the connecting rod 19 to rotate by an angle and drives the shaft pin 20 to move upward. During the upward movement of the shaft pin 20, it drives the connecting plate 21 and the sliding shaft 22 to move upward. When the sliding shaft 22 moves upward to the upper part of the sliding groove 23, part of it will slide into the inclined part on the side. At this time, the connecting plate 21 undergoes an angular flip, thereby driving the top plate 24 and the telescopic rod 25 to undergo an angular flip and driving the pressing plate 26 to flip away from above the support seat 3. At this time, the pressing plate 26 is in an inclined state. Then place the outer tube of the shock absorber in the middle of the support seat 3. At the same time, start the first motor 4 to drive the gear 5 to rotate. During the rotation of the gear 5, it drives the two rack plates 6 to slide. At the same time, through the sliding of the two rack plates 6, it drives the two connecting blocks 7 to rotate by an angle, prompting the two connecting blocks 7 to drive the clamping rods 9 to slide inside the support plate 8 and making the two clamping rods 9 approach each other to clamp the outer wall of the shock absorber outer tube, preventing the shock absorber outer tube from shifting during the hardness test. At this time, start the second motor 14 to drive the driving wheel 15 to rotate in the reverse direction. The driving wheel 15 drives the driven wheel 16 and the connecting shaft 17 to rotate in the reverse direction, so that the rotating rod 18 slowly rotates from an inclined angle to a vertical angle. While the rotating rod 18 rotates by an angle, it drives the connecting rod 19 to rotate by an angle and drives the shaft pin 20 to move downward. During the downward movement of the shaft pin 20, it drives the connecting plate 21 to move downward and drives the sliding shaft 22 to slide, so that the sliding shaft 22 slides into the vertical part of the sliding groove 23, prompting the connecting plate 21 to rotate by an angle, making the connecting plate 21 drive the top plate 24 to flip and lie flat directly above the shock absorber outer tube. At this time, start the two telescopic rods 25 to drive the pressing plate 26 to press down and perform a hardness test on the shock absorber outer tube. The test result is displayed by the detector 27. This process can not only achieve the effect of automatic hardness detection, but also realize the flipping of the top plate 24, facilitating the auxiliary placement and clamping operation of the shock absorber outer tube.
