Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber lifting ring measurement, in particular to a shock absorber lifting ring chamfer diameter measuring tool. Background Art

[0002] The shock absorber lifting ring is an important component of the shock absorber. It is a connecting component, usually in a ring structure, and is mainly used to install the shock absorber to the vehicle frame or other equipment structure that requires shock absorption. In terms of shape, it is similar to a ring with an opening or a closing. The size and shape of the ring will vary according to different shock absorber models and application scenarios. The shock absorber lifting ring chamfer diameter measuring tool is a device specially used to accurately measure the diameter of the chamfer part of the shock absorber lifting ring. The main function is to obtain the diameter size data of the chamfer of the shock absorber lifting ring through a specific measuring structure and method. This data is crucial to ensuring the quality and performance of the shock absorber lifting ring, because the accuracy of the chamfer diameter will affect the installation of the lifting ring, the force distribution and the coordination with other components.

[0003] When measuring the chamfer diameter of the shock absorber lifting ring, the lifting ring needs to be positioned. The working principle is: put the lifting ear with the completed chamfer diameter into the inspection fixture hole and position it by the reference surface. If one end of the lifting ear protrudes from the through gauge surface and is lower than the stop gauge surface, the chamfer diameter is qualified. Take out the lifting ear and inspect the other end surface.

[0004] In the prior art, some measuring devices use a reference plane to position the lifting ring. However, relying solely on the reference plane for positioning will cause the lifting ring to be unstable during the measurement process. When there are slight irregularities in the chamfer shape of the lifting ring or there are certain tolerances in the size, the lifting ring cannot be positioned well, thereby affecting the accuracy of the chamfer diameter measurement. Therefore, a shock absorber lifting ring chamfer diameter measuring tool is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3The utility model provides an embodiment of a shock absorber lifting ring chamfer diameter measuring tool, comprising a measuring disc 1, which is the core bearing component of the entire measuring tool and provides a platform for installation and operation of other parts. A stop gauge surface 2 is provided on the external top of the measuring disc 1. The stop gauge surface 2 is a flat and smooth surface. Its main function is to contact a specific part of the shock absorber lifting ring during measurement to achieve precise positioning. A reference surface 3 is provided inside the measuring disc 1. The reference surface 3 provides a stable reference standard for measurement. A through gauge surface 4 is provided on the right side of the top of the measuring disc 1 to detect whether the lifting ring is qualified.

[0033] One end of the lifting ear protrudes from the through gauge surface 4 and is lower than the stop gauge surface 2, then the chamfer diameter is qualified. The left and right ends of the interior of the measuring disk 1 are fixedly connected with sleeve columns 5, and the interior of the sleeve column 5 is slidably connected with a sliding rod 6. The sliding rod 6 can slide in the sleeve column 5, so that the sliding rod 6 can flexibly adjust the appropriate positioning position according to the size and shape of the shock absorber lifting ring, thereby realizing the adaptive positioning of lifting rings of different specifications, improving the versatility of the measuring tool, the outer sliding rod 6 is slidably connected to the interior of the measuring disk 1, and the outer rear end of the sliding rod 6 is fixedly connected to the limiting block 7. The function of the limiting block 7 is to limit the sliding range of the sliding rod 6 in the sleeve column 5 to prevent sliding The rod 6 is accidentally dislodged from the sleeve column 5 during the movement, which ensures the integrity and safety of the entire structure. The outer portion of the limit block 7 is slidably connected to the inside of the sleeve column 5. The outer sleeve of the sliding rod 6 is provided with a spring 8. When the sliding rod 6 is moved by an external force, the spring 8 will be compressed or stretched accordingly, storing elastic potential energy, and after the force disappears, it uses its own elastic restoring force to push the sliding rod 6 back to its original position. The other end of the spring 8 is fixedly connected to the external front end of the sleeve column 5, and the adjacent side of the sliding rod 6 is fixedly connected with a positioning plate 9. The positioning plate 9 is fixedly connected to the sliding rod 6 to achieve synchronous movement with the sliding rod 6.

[0034] During the measurement process, the positioning plate 9 is in direct contact with the shock absorber lifting ring, and adjusts its own position according to the size of the lifting ring to provide accurate positioning for the measurement. The adjacent sides of the two positioning plates 9 are in contact, and the outer side of the positioning plate 9 is slidably connected to the inside of the measuring disk 1. One end of the spring 8 is fixedly connected to the far side of the positioning plate 9, and the adjacent side of the positioning plate 9 is fixedly connected with a protective component for pressure resistance.

[0035] Reference Figure 2 、 Figure 4The protective component includes a gasket 10, which is an important part of the protective component and is directly installed on the positioning plate 9 to play a buffering and protective role. The outside of the gasket 10 is fixedly connected to the adjacent side of the positioning plate 9. A sliding groove 11 is provided inside the measuring disk 1. The sliding groove 11 provides a track for the sliding of the gasket 10. The outside of the gasket 10 is slidably connected to the inside of the sliding groove 11. The inside of the gasket 10 is fixedly connected with a pressure-resistant layer 12. The main function of the pressure-resistant layer 12 is to withstand the large pressure occurring during the measurement process and to prevent the gasket 10 from being deformed or damaged under high pressure. The material of the pressure-resistant layer 12 is carbon steel. The bottom end of the pressure-resistant layer 12 is fixedly connected with a filling layer 13. The material of the filling layer 13 is asbestos. The outside of the filling layer 13 is fixedly connected to the inner bottom end of the gasket 10.

[0036] Working principle: When using the shock absorber lifting ring chamfer diameter measuring tool, first place the shock absorber lifting ring in the measuring disc 1, and the lifting ring contacts the gauge surface 2. When the lifting ring enters the measuring disc 1, it squeezes the two positioning plates 9, so that the positioning plates 9 drive the sliding rod 6 to slide in the sleeve column 5. The limit block 7 at the rear end of the sliding rod 6 slides in the sleeve column 5 to ensure that the sliding rod 6 does not separate from the sleeve column 5. When the sliding rod 6 slides, the spring 8 is compressed. The spring 8 is deformed by the force and accumulates elastic potential energy. At the same time, the positioning plate 9 drives the gasket 10 to slide. The ring slides in the groove 11, and the pressure-resistant layer 12 inside the gasket 10 bears the pressure to prevent the ring from being damaged due to excessive pressure during the measurement process. The filling layer 13 below the pressure-resistant layer 12 can fill the tiny gap. When the ring is completely placed, the chamfer diameter of the ring is determined by measuring the distance between the two positioning plates 9. After the measurement is completed, the spring 8 releases its elastic potential energy, pushing the positioning plate 9 back to its initial position, driving the sliding rod 6 to slide in the opposite direction in the sleeve column 5, and then restoring the entire device to its initial state for the next measurement.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
