Description

Technical Field

[0001] This utility model relates to mechanical equipment for manufacturing shock absorbers, specifically to a shock absorber lifting ring rubber bushing pressing device. Background Technology

[0002] Shock absorber collars are important components connecting the vehicle body and the shock absorber housing. During the production of shock absorbers, rubber bushings need to be press-fitted into the collars. Rubber bushings can reduce direct friction and wear between metal parts, extend the service life of the collars and the entire suspension system, and at the same time, rubber materials have a certain degree of elasticity, allowing for a certain degree of deformation when subjected to external forces, thus adapting to different road conditions and driving conditions.

[0003] To improve production efficiency and profitability, the press-fitting of rubber bushings for shock absorber lifting rings requires specialized machinery. Existing technologies typically employ a downward pressing method (e.g., a shock absorber lifting lug rubber bushing press-fitting machine disclosed in Chinese patent document CN211102558U), pressing the rubber bushing into the shock absorber lifting ring from top to bottom. Because rubber material deforms under compression, the friction between the outer circumference of the rubber bushing and the lifting ring during press-fitting causes the rubber bushing to bulge in the center, preventing complete press-fitting in one go. Therefore, the rubber bushing is first over-pressed (i.e., pressed beyond the design position), and then the deformation is corrected by reverse pressing. However, when using existing press-fitting equipment, the positioning fixture below the shock absorber lifting ring prevents the installation of a reverse pressing mechanism. The shock absorber must be rotated 180° to perform reverse pressing, which is cumbersome and inefficient. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a rubber bushing pressing device for shock absorber lifting rings. This pressing device adopts a specific structure and uses a transverse pressing method instead of the longitudinal pressing method of the existing technology. After the forward over-pressing is completed, it is not necessary to rotate the shock absorber 180° to perform reverse back-pressing. The entire process only requires positioning the lifting ring once, which simplifies the process and improves the processing efficiency.

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

[0006] A shock absorber lifting ring rubber bushing pressing device includes a frame; a lifting ring positioning seat is provided on the frame, and a positioning cylinder is provided above the lifting ring positioning seat; the front end of the piston rod of the positioning cylinder is connected to a positioning block through a positioning connecting sleeve; the positioning block can cooperate with the lifting ring positioning seat after being pressed down to position the shock absorber lifting ring; a support seat is provided on the frame for placing the shock absorber; a pressing cylinder and an adjusting cylinder are respectively provided on both sides of the lifting ring positioning seat, and the front end of the piston rod of the pressing cylinder is connected to a bushing pressing cylinder through a pressing connecting sleeve. The bushing block has a bushing mounting shaft at its end, which engages with the through hole of the rubber bushing to position the rubber bushing. The piston rod of the adjusting cylinder is connected to a bushing adjusting block via an adjusting connecting sleeve. The bushing adjusting block has a bushing adjusting shaft at its end, which engages with the through hole of the rubber bushing. The pressing cylinder drives the bushing block to press the rubber bushing mounted on the bushing block into the shock absorber ring. The adjusting cylinder also drives the bushing adjusting block to reverse the pressure of the rubber bushing.

[0007] Compared with the prior art, the shock absorber ring rubber bushing pressing device of this utility model sets up a ring positioning seat for positioning the shock absorber ring, and sets up a positioning block that can be driven by a cylinder above the ring positioning seat to fix the shock absorber ring, so that the shock absorber ring can withstand lateral pressure. At the same time, a bushing pressing block and a bushing adjusting block that can be driven by a cylinder are respectively set on both sides of the ring positioning seat for positive overpressure and reverse backpressure. After the positive overpressure is completed, the shock absorber ring does not need to be rotated 180° to perform reverse backpressure. In the whole process, the shock absorber ring only needs to be positioned once, which makes the process simpler and the work efficiency higher.

[0008] Furthermore, in the aforementioned shock absorber lifting ring rubber bushing pressing device, the frame is equipped with a pressing slide assembly, and the pressing connecting sleeve is disposed on the pressing slide assembly, enabling it to move linearly on the pressing slide assembly under the drive of the pressing cylinder. The connection between the pressing connecting sleeve and the pressing slide assembly ensures the accuracy and stability of the motion trajectory, improving pressing precision. Further, the pressing slide assembly includes a connecting plate and a pressing slide. The connecting plate is disposed on the pressing slide and can move linearly on the pressing slide. The connecting plate has a U-shaped groove, and the pressing connecting sleeve has a limiting groove. The limiting groove and the U-shaped groove cooperate to limit the pressing connecting sleeve. Connecting the pressing connecting sleeve and the pressing slide through the limiting groove on the pressing connecting sleeve and the U-shaped groove on the connecting plate is easy to implement and simple to assemble.

[0009] Furthermore, in the aforementioned shock absorber lifting ring rubber bushing pressing device, the lifting ring positioning seat is provided with an arc-shaped positioning groove, and the lower surface of the positioning block is provided with an arc-shaped pressing groove. The arc-shaped positioning groove can limit the movement of the shock absorber lifting ring, and the arc-shaped pressing groove can press and fix the shock absorber lifting ring. The arc-shaped positioning groove and the arc-shaped pressing groove can fit with the surface of the shock absorber lifting ring during processing, achieving positioning and improving processing stability. Furthermore, the bottom of the lifting ring positioning seat is provided with a limiting post, and the frame is provided with a limiting hole that mates with the limiting post. The limiting post is inserted into the limiting hole to limit the movement of the lifting ring positioning seat; the positioning block and the positioning connecting sleeve are connected to each other by threads. The lifting ring positioning seat and positioning block of this structure can be replaced according to the type of shock absorber, making it widely applicable. The cross-sectional shape of the limiting post is semi-circular.

[0010] Furthermore, in the aforementioned shock absorber lifting ring rubber bushing pressing device, the support base is provided with a support groove, which is V-shaped. The V-shaped structure enables the positioning of the shock absorber, ensuring the stability of the shock absorber housing during processing, guaranteeing processing accuracy, and facilitating processing.

[0011] Furthermore, in the aforementioned shock absorber eyelet rubber bushing pressing device, the bushing pressing block and the pressing connecting sleeve are connected to each other by threads, and the bushing adjusting block and the adjusting connecting sleeve are connected to each other by threads. This threaded connection method allows for the replacement of the bushing pressing block and the bushing adjusting block according to the type of rubber bushing, making it widely applicable.
