Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber welding technology, specifically to a press-fitting fixture for a shock absorber reservoir cylinder. Background Technology

[0002] As the automotive industry rapidly develops towards lightweight and high reliability, the manufacturing precision and sealing performance of automotive shock absorbers, as the core component of the vehicle suspension system, directly affect the NVH performance and service life of the entire vehicle. Among them, the press-fitting process of the reservoir assembly is a key link to ensure the sealing performance and reliability of the shock absorber.

[0003] Existing technologies generally employ semi-automatic hydraulic pressing equipment in conjunction with manual positioning. In practice, the reservoir seat must first be placed at the bottom of the fixture, and then the reservoir is manually aligned for pressing. This "cylinder on top, seat below" method relies heavily on the operator's experience to adjust the axial coaxiality, making it difficult to meet industry precision standards. This results in large coaxiality deviations and insufficient sealing performance of the workpiece after pressing, which in turn leads to premature failure of the shock absorber. Furthermore, this working method of semi-automatic hydraulic pressing equipment combined with manual positioning also poses a safety hazard of pressing the hand due to misoperation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a press-fitting tool for the shock absorber reservoir cylinder, so as to improve assembly accuracy and reduce installation risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a press-fitting fixture for a shock absorber reservoir cylinder, including a base plate, a guide shaft, a top plate, and an elastic element; The guide shaft is vertically disposed on the base plate, the top plate is slidably disposed on the guide shaft, the top plate is provided with a positioning seat for placing the workpiece, and the base plate is also provided with a mandrel for placing one end of the workpiece, the mandrel and the positioning seat are coaxially disposed; The elastic element is disposed on the side of the top plate facing the bottom plate and is used to provide a constant restoring force to the top plate.

[0006] In some embodiments, a retaining ring is further included, the retaining ring being fixed to the guide shaft, and the elastic element being disposed between the retaining ring and the top plate.

[0007] In some embodiments, a guide shaft support is further included, which is fixedly disposed on the base plate, and the guide shaft is mounted on the base plate through the guide shaft support.

[0008] In some embodiments, a guide shaft bearing disposed between the top plate and the guide shaft is also included.

[0009] In some embodiments, the top plate is arranged parallel to the bottom plate via the guide shaft, and the positioning seat is axially aligned with the mandrel.

[0010] In some embodiments, the elastic element includes a spring.

[0011] Furthermore, the beneficial effects of this utility model are as follows: This utility model sets a guide shaft perpendicular to the base plate and a top plate slidably set on the guide shaft. At the same time, this utility model also sets a positioning seat on the top plate and a mandrel coaxial with the positioning seat on the base plate. Thus, when part of the workpiece to be pressed is installed into the positioning seat, the other part of the workpiece to be pressed is sleeved on the mandrel, which can achieve the effect of precise positioning and eliminate the need for manual straightening intervention. Furthermore, the elastic element in this invention is used to provide a restoring force to the top plate at all times. After the workpiece to be pressed is completed, the elastic element, in conjunction with the guide shaft sliding structure, can automatically reset the top plate, thereby effectively improving the pressing efficiency and stability.

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 scope of protection of the present utility model.

For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. In addition, in the description of the embodiments of the present utility model, "multiple" means two or more. Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more.

[0015] like Figure 1 As shown, this utility model provides a press-fitting fixture for a shock absorber reservoir cylinder, including a base plate 1, a guide shaft 3, a top plate 6, and an elastic element 5; The guide shaft 3 is vertically mounted on the base plate 1, and the top plate 6 is slidably mounted on the guide shaft 3. The top plate 6 is provided with a positioning seat 8 for placing the workpiece, and the base plate 1 is also provided with a mandrel 9 for placing one end of the workpiece. The mandrel 9 and the positioning seat 8 are coaxially mounted. The elastic element 5 is disposed on the side of the top plate 6 facing the bottom plate 1 and is used to provide a restoring force to the top plate 6 at all times. In the above structure, this utility model needs to be used in conjunction with a liquid storage cylinder and a liquid storage cylinder seat. The liquid storage cylinder seat is disposed in the positioning seat 8 of this utility model, and the liquid storage cylinder is sleeved on the mandrel 9. Based on this, this utility model achieves the effect of accurately positioning the liquid storage cylinder and the liquid storage cylinder seat by setting the vertical guide shaft 3, the sliding top plate 6, the coaxial mandrel 9 and the positioning seat 8 and the elastic element 5.

[0016] In addition, in specific implementation, the operator first puts one end of the liquid storage cylinder workpiece into the mandrel 9 fixed on the base plate 1, so that the liquid storage cylinder is positioned along the axial direction of the mandrel 9. Then, the liquid storage cylinder seat workpiece is placed in the positioning seat 8 slidably set on the top plate 6 of the guide shaft 3. The radial limit is achieved by the contour of the positioning seat 8. The external hydraulic press equipment is started, and its pressure head applies downward pressure, which drives the top plate 6 to slide smoothly along the guide shaft 3 vertically fixed to the base plate 1 towards the base plate 1. At the same time, the elastic element 5 set on the side of the top plate 6 facing the base plate 1 is compressed. During the sliding process, the mandrel 9 and the positioning seat 8 remain coaxially aligned to ensure that the liquid storage cylinder seat is accurately and evenly pressed into the liquid storage cylinder to form a tight assembly. After the press is in place, the hydraulic press head rises to release the pressure, and the elastic element 5 immediately rebounds, pushing the top plate 6 to slide in the opposite direction along the guide shaft 3 to the initial position. Finally, the operator can directly remove the finished liquid storage cylinder assembly from the positioning seat 8 and the mandrel 9.

[0017] This invention features a guide shaft 3 perpendicular to the base plate 1 and a top plate 6 slidably mounted on the guide shaft 3. Additionally, a positioning seat 8 is mounted on the top plate 6, and a mandrel 9 coaxial with the positioning seat 8 is mounted on the base plate 1. This allows for precise positioning and eliminates the need for manual intervention when one part of the workpiece to be pressed is installed inside the positioning seat 8, while the other part is mounted on the mandrel 9.

[0018] One possible implementation also includes a fixing ring 4, which is fixed to the guide shaft 3, and an elastic element 5 is disposed between the fixing ring 4 and the top plate 6. With the above design, the effect of uniform elastic force distribution and stable and controllable sliding stroke of the top plate 6 is achieved.

[0019] One possible implementation method also includes a guide shaft support 2 fixedly mounted on the base plate 1, and the guide shaft 3 is mounted on the base plate 1 through the guide shaft support 2. The guide shaft support 2 is used to mount the guide shaft 3, thereby achieving the effect of enhancing structural rigidity, reducing vibration deviation, and extending the service life of the tooling to a certain extent.

[0020] In some embodiments, a guide shaft bearing 7 is also provided between the top plate 6 and the guide shaft 3. During the pressing process, the guide shaft bearing 7 can effectively improve the stability of the top plate 6 during pressing.

[0021] In one possible implementation, the top plate 6 is set parallel to the bottom plate 1 via the guide shaft 3, and the positioning seat 8 and the mandrel 9 are aligned axially. This parallel alignment design enables a more uniform distribution of pressing force, avoids workpiece skewing, and ensures the coaxiality of the assembly.

[0022] In one possible implementation, the elastic element 5 includes a spring. By setting a spring as the elastic element 5, this utility model achieves the effects of reliable reset force, simple and durable structure, and reduced maintenance cost. It is used to always provide reset force to the top plate 6. When the workpiece to be pressed is pressed, the elastic element 5, in conjunction with the sliding structure of the guide shaft 3, can automatically reset the top plate 6, thereby effectively improving the pressing efficiency and stability.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
