Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically to an adaptive clamp for shock absorbers. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the vehicle. When driving over uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves will still have reciprocating motion. Shock absorbers are used to suppress this spring bounce. During their manufacturing, assembly, or repair, shock absorbers often need to be fixed and clamped for subsequent processing, testing, or assembly operations.

[0003] In practical applications, most current shock absorber fixtures lack self-adaptive capabilities and cannot automatically adjust the clamping range and clamping force according to the workpiece size, resulting in poor versatility. Therefore, an adaptive shock absorber fixture is needed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive clamp for shock absorbers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An adaptive clamp for a shock absorber includes a base plate, a clamping assembly, and a positioning plate. The base plate has a vertical plate on top, and a mounting frame is provided on one side of the vertical plate. A cam disk is provided inside the mounting frame, and a rotating shaft is provided on one side of the cam disk. The rotating shaft is fitted onto the mounting frame. The clamping assembly includes a rectangular block, one end of which is connected to the inner wall of the mounting frame. A guide groove is provided on the rectangular block, and a slide rod is fitted inside the guide groove. A square block is provided at one end of the slide rod, and a connecting block is provided at one end of the square block. A clamping plate is provided at one end of the connecting block. A sliding groove is provided on the other side of the cam disk, and the other end of the slide rod is fitted into the sliding groove.

[0006] As a preferred embodiment of this utility model, a bearing is provided on the vertical plate, and the rotating shaft is set in the inner ring of the bearing. The bearing is used to support the rotating shaft, ensuring that the rotating shaft and the cam disk on it can rotate smoothly and accurately with minimal frictional resistance, while bearing radial force to ensure motion accuracy and lifespan.

[0007] As a preferred embodiment of this utility model, a drive source is provided on the other side of the vertical plate. The output end of the drive source is connected to the rotating shaft. The drive source is a motor, which provides the power source.

[0008] As a preferred embodiment of this utility model, limit grooves are respectively opened on both sides of the guide groove, and two symmetrical limit sliders are provided on the outside of the slide rod. The two limit sliders are respectively engaged in the limit groove. The limit groove and the limit slider are auxiliary structures for preventing disengagement and enhancing stability of the guide groove mechanism, preventing the slide rod from tilting or falling out of the guide groove during movement, greatly enhancing the rigidity and stability of the entire clamping assembly when subjected to clamping force, avoiding jamming, and ensuring smooth movement.

[0009] As a preferred embodiment of this utility model, a rubber pad is provided on the inner side of the clamping plate. The rubber pad prevents the metal clamping plate from directly scratching the surface of the shock absorber, absorbs slight vibrations, and adapts to minor unevenness on the surface of the workpiece.

[0010] As a preferred embodiment of this utility model, the inner surface of the rubber pad is evenly provided with several friction bumps. The friction bumps further increase the static friction of the contact surface, "biting" the workpiece surface like tire treads, effectively preventing the workpiece from slipping or rotating during processing.

[0011] As a preferred embodiment of this invention, three clamping components are provided, which are evenly arranged on the inner side of the mounting frame. The three evenly distributed clamping components ensure that the three grippers are evenly distributed at 120°, which is the geometric basis for achieving automatic centering. Regardless of the workpiece diameter, its center will eventually be stably positioned on the theoretical center line of the fixture, ensuring extremely high coaxiality.

[0012] As a preferred embodiment of this utility model, the positioning plate is arranged between three rectangular blocks, and a positioning rod is provided on one side of the positioning plate. The positioning plate and the positioning rod constitute an axial positioning mechanism. When the workpiece is placed into the fixture, its end can abut against the positioning plate or the positioning rod, thereby quickly determining the axial position of the workpiece.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this invention, the self-adaptive function of the fixture is achieved through the ingenious cooperation between the cam disk and the three clamping components. When the drive source rotates the cam disk, the sliding groove on it simultaneously drives the three sliding rods to move along the guide groove, thereby synchronously controlling the radial opening or closing of the three clamping plates. This design enables the fixture to automatically adapt to and stably clamp shock absorber workpieces of different diameters, significantly improving the versatility and applicability of the fixture, eliminating the need for frequent fixture changes for different workpiece specifications.

[0014] 2. In this invention, the positioning plate and positioning rod located at the center provide initial axial positioning for the workpiece, facilitating rapid placement and alignment. Furthermore, the three clamping components are evenly and symmetrically distributed, ensuring that the clamping force is uniformly applied to the circumference of the workpiece. The sliding groove of the cam disc guarantees the synchronous movement of the three jaws, fundamentally avoiding the problem of workpiece skewing or loosening due to unilateral force, achieving excellent automatic centering, and greatly improving clamping stability and positioning accuracy in subsequent processing.

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0019] For examples, please refer to Figure 1-4 This utility model provides a technical solution: An adaptive clamp for a shock absorber includes a base plate 1, a clamping assembly 6, and a positioning plate 7. The base plate 1 serves as the foundation and mounting platform for the entire clamping device. A vertical plate 2 is located on the top of the base plate 1, acting as the main vertical support structure for mounting and supporting other core components. A mounting frame 4 is provided on one side of the vertical plate 2, accommodating and mounting a cam disk 5 and the clamping assembly 6. The cam disk 5 is located inside the mounting frame 4 and is the core drive mechanism of the entire clamp. A rotating shaft 501 is located on one side of the cam disk 5, transmitting power and fitting onto the mounting frame 4. The clamping assembly 6 includes a rectangular block 601, one end of which is connected to the inner wall of the mounting frame 4. The rectangular block 601 serves as the mounting base for the clamping assembly 6. The base is fixed on the mounting frame 4. A guide groove 602 is provided on the rectangular block 601. A slide rod 604 is fitted inside the guide groove 602. The guide groove 602 provides a precise and preset path guide for the movement of the slide rod 604, forcing the slide rod 604 to move only along this trajectory, ensuring the determinism of the movement. One end of the slide rod 604 is provided with a square block 606, and one end of the square block 606 is provided with a connecting block 607. The square block 606 and the connecting block 607 are used to connect the slide rod 604 and the clamping plate 608. One end of the connecting block 607 is provided with the clamping plate 608. The clamping plate 608 is the part that directly contacts the workpiece and transmits the clamping force. The other side of the cam disk 5 is provided with a slide groove 502, and the other end of the slide rod 604 is fitted in the slide groove 502.

[0020] In this embodiment, a bearing 201 is provided on the vertical plate 2, and a rotating shaft 501 is disposed in the inner ring of the bearing 201. The bearing 201 is used to support the rotating shaft 501, ensuring that the rotating shaft 501 and the cam disk 5 on it can rotate smoothly and accurately with minimal frictional resistance, while bearing radial force to ensure motion accuracy and lifespan.

[0021] In this embodiment, a drive source 3 is provided on the other side of the vertical plate 2. The output end of the drive source 3 is connected to the rotating shaft 501. The drive source 3 is a motor that provides a power source.

[0022] In this embodiment, limiting grooves 603 are respectively provided on both sides of the guide groove 602, and two symmetrical limiting sliders 605 are provided on the outside of the slide rod 604. The two limiting sliders 605 are respectively engaged in the limiting grooves 603. The limiting grooves 603 and the limiting sliders 605 are auxiliary structures for preventing the slide rod 604 from getting off and enhancing its stability. They prevent the slide rod 604 from tilting up or falling off from the guide groove 602 during movement, greatly enhancing the rigidity and stability of the entire clamping assembly 6 when subjected to clamping force, avoiding jamming, and ensuring smooth movement.

[0023] In this embodiment, a rubber pad 609 is provided on the inner side of the clamping plate 608. The rubber pad 609 prevents the metal clamping plate 608 from directly scratching the surface of the shock absorber, absorbs slight vibrations, and adapts to the slight unevenness of the workpiece surface.

[0024] In this embodiment, the inner surface of the rubber pad 609 is evenly provided with a plurality of friction protrusions 6010. The friction protrusions 6010 further increase the static friction of the contact surface, "biting" the workpiece surface like tire treads, effectively preventing the workpiece from slipping or rotating during processing.

[0025] In this embodiment, three clamping components 6 are provided, which are evenly arranged inside the mounting frame 4. The three evenly distributed clamping components 6 make the three jaws evenly distributed at 120°, which is the geometric basis for achieving automatic centering. Regardless of the diameter of the workpiece, its center will eventually be stably positioned on the theoretical center line of the fixture, ensuring extremely high coaxiality.

[0026] In this embodiment, the positioning plate 7 is disposed between three rectangular blocks 601, and a positioning rod 701 is provided on one side of the positioning plate 7. The positioning plate 7 and the positioning rod 701 constitute an axial positioning mechanism. When the workpiece is placed into the fixture, its end can press against the positioning plate 7 or the positioning rod 701, thereby quickly determining the axial position of the workpiece.

[0027] The working process of this utility model is as follows: When the shock absorber adaptive clamp and structure designed in this solution are in operation, the outer cylinder of the shock absorber is first installed on the positioning rod 701. Then, the drive source 3 is started, and the drive source 3 drives the rotating shaft 501 to rotate. The rotating shaft 501 transmits torque to the cam disk 5 fixed on it. The rotation of the cam disk 5 causes the sliding groove 502 on its end face to rotate accordingly. The curved surface of the sliding groove 502 pushes the end of the sliding rod 604, forcing the sliding rod 604 to move. The middle part of the sliding rod 604 fits in the guide groove 602 on the rectangular block 601. The cooperation between the limiting slider 605 and the limiting groove 603 ensures that the slide rod 604 can only move in a straight line along the trajectory specified by the guide groove 602. Then, the slide rod 604 pushes the clamping plate 608 to move towards the center through the block 606 and the connecting block 607. The three evenly distributed clamping plates 608 simultaneously contact the outer wall of the shock absorber workpiece, and the workpiece is automatically adjusted and fixed at the theoretical center position of the fixture, achieving high-precision self-centering, thereby completing the clamping.
