Description

Technical Field

[0001] This utility model relates to mechanical equipment for the production of shock absorbers, specifically to press-fitting equipment for pressing snap rings into shock absorber connecting rods. Background Technology

[0002] Shock absorbers are an important component of a car's suspension system, playing a crucial role in improving driving stability and ride comfort. When a vehicle encounters a large impact or vibration, the shock absorber link will be stretched or compressed to its limit. Therefore, rubber or plastic buffer blocks need to be fitted onto the shock absorber link to restrict its movement and prevent damage to related components due to rigid collisions.

[0003] Placing a buffer block on the upper side of the piston valve is a common practice. To limit the movement of the buffer block, a retaining ring is needed on the connecting rod. In existing technology, the retaining ring is installed on the shock absorber connecting rod manually by pressing. During the pressing process, the worker first inserts the buffer block onto the connecting rod, and then uses a tool to manually tap the retaining ring from the end of the shock absorber connecting rod into the retaining ring groove on the connecting rod. However, this manual pressing method makes it difficult to guarantee the accuracy of the pressing, often resulting in incomplete pressing and rework. At the same time, the pressing process relies on manual operation, which is labor-intensive and inefficient. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model provides a press-fitting device for pressing snap rings into shock absorber connecting rods. This press-fitting device enables automated press-fitting of snap rings, ensuring accuracy and improving precision, effectively avoiding rework caused by incomplete press-fitting. Furthermore, during the press-fitting process, only the connecting rod needs to be positioned, making operation simple, time-saving, labor-saving, and highly efficient.

[0005] The technical solution of this utility model is as follows:

[0006] A pressing device for pressing a retaining ring into a shock absorber connecting rod includes a frame; the frame is equipped with a pressing device and a positioning device, the positioning device being used to position the shock absorber connecting rod, and the pressing device being used to press the retaining ring into a retaining ring groove on the shock absorber connecting rod; the pressing device includes a hydraulic cylinder, a mounting plate, and a pressing sleeve; the mounting plate is located on the upper part of the frame, the hydraulic cylinder is fixed to the mounting plate, and the output end of the hydraulic cylinder passes through the mounting plate and is connected to the pressing sleeve; the bottom of the pressing sleeve is provided with a pressing ring, which can act on the retaining ring to press it into the shock absorber connecting rod. The positioning device includes a base plate, an upper plate, a fixed seat, a support plate, and a base assembly. The base plate is placed on the worktable of the frame, and the upper plate is fixedly placed above the base plate. The upper plate is provided with a fixed seat, and the fixed seat has a connecting rod mounting groove along its vertical edge. The opening at the top of the connecting rod mounting groove allows the shock absorber connecting rod to pass through. The upper end of the connecting rod mounting groove is provided with a step, and the opening angle α at this point is less than 180°. The step surface is used for axial positioning of the buffer block. The base assembly is placed on the base plate and is used to support the end of the shock absorber connecting rod.

[0007] Compared with existing technologies, the pressing equipment of this utility model for pressing circlips into shock absorber connecting rods utilizes the cooperation of a pressing device and a positioning device to press the circlip into the circlip groove at the end of the shock absorber connecting rod during the circlip pressing process. This ensures the accuracy of the pressing, improves the pressing precision, and effectively avoids rework caused by incomplete pressing. During the pressing process, the positioning device limits the shock absorber connecting rod, and then the pressing sleeve is pressed down, using the pressing ring at its bottom to press the circlip into the circlip groove. Throughout the entire pressing process, the worker only needs to install and position the connecting rod, making the operation simple, time-saving, and highly efficient.

[0008] Furthermore, in the aforementioned press-fitting equipment for pressing the retaining ring into the shock absorber connecting rod, the two ends of the mounting plate are connected to the worktable of the frame via guide posts, and the output end of the hydraulic cylinder is connected to a movable plate, the two ends of which are respectively in sliding engagement with two guide posts. The guide posts ensure structural stability and high reliability.

[0009] Furthermore, in the aforementioned press-fitting device for pressing the retaining ring into the shock absorber connecting rod, the output end of the hydraulic cylinder is connected to the press-fitting sleeve via a connecting sleeve, and the press-fitting sleeve and the connecting sleeve are detachably connected. This detachable connection between the press-fitting sleeve and the connecting sleeve allows the press-fitting sleeve to be replaced according to the type of shock absorber, thus expanding the device's applicability.

[0010] Furthermore, in the aforementioned press-fitting equipment for pressing the retaining ring into the shock absorber connecting rod, the base assembly includes a base and an electric cylinder. The electric cylinder is fixed to the base plate, and the base is connected to the output end of the electric cylinder. The electric cylinder can adjust the position of the base in the vertical direction. Adjusting the position of the base via the electric cylinder allows it to accommodate shock absorber connecting rods of different lengths, enhancing its applicability. Furthermore, the base is provided with a positioning groove, which is V-shaped. The V-shaped structure can limit the lifting ring at the bottom of the shock absorber connecting rod, preventing it from shifting during press-fitting, ensuring press-fitting accuracy, and offering the advantage of ease of implementation.

[0011] Furthermore, the aforementioned press-fitting equipment for pressing the retaining ring into the shock absorber connecting rod also includes a transition sleeve for fitting onto the end of the shock absorber connecting rod, the top of which is tapered. The transition sleeve guides the retaining ring, ensuring that it is accurately pressed into place during the press-fitting process, while also preventing scratches on the surface of the shock absorber connecting rod during the press-fitting process.

[0012] Furthermore, in the aforementioned press-fitting device for pressing the retaining ring into the shock absorber connecting rod, the upper end of the fixing seat is provided with a positioning platform, and correspondingly, the upper plate is provided with a fixing seat mounting groove. The fixing seat mounting groove cooperates with the positioning platform to limit the fixing seat and is fixed by bolts. This structure for limiting the fixing seat facilitates installation and replacement of the fixing seat. The fixing seat can be replaced according to the type of shock absorber connecting rod, making this device adaptable to various types of shock absorber connecting rods, thus demonstrating strong applicability.

[0013] Furthermore, in the aforementioned press-fitting equipment for pressing the retaining ring into the shock absorber connecting rod, a support plate is provided on each side of the base plate, and the two ends of the upper plate are respectively fixedly connected to the upper ends of the two support plates.
