Description

Technical Field

[0001] The present application relates to the field of press-fit equipment for automobile parts, and in particular to a floating installation mechanism and a press-fit equipment. Background Art

[0002] Shock absorber bushing is a commonly used automotive component, widely used in the automotive suspension system. As an important part of the automotive suspension system, the shock absorber bushing can protect other suspension components. It can reduce the wear and vibration of various components in the suspension system and increase the service life of the entire suspension system.

[0003] At present, bushings are mostly press-fitted, but the components that need to be press-fitted are large in size and bushings need to be installed in many places. And because the components to be installed themselves have certain structural errors, the positions of the mounting holes of the bushings to be installed on their surfaces may also have deviations. Therefore, there are certain limitations in the bushing press-fitting opportunities with fixed assembly positions. In October 2023, our company proposed "A Subframe Pressing Equipment", application number: CN202311296497.1, which discloses a rotating platform connected to a servo motor, and a stamping device arranged on one side of the rotating platform. The servo rotating platform is provided with a pressing assembly for fixing the subframe, and a floating seat. The subframe is mounted on the servo rotating platform and fixed by the pressing assembly. The mounting hole of the subframe is installed on the floating seat. The floating seat is deformed when subjected to force. The servo motor drives the rotating platform to rotate and drives the floating seat to move to the bottom of the stamping device. The stamping device works to press the bushing into the mounting hole of the subframe. A floating seat is provided to adapt to the sub-frame mounting hole with a certain deviation; a rotating platform is provided to rotate the bushing and the sub-frame to the press-fitting position to cooperate in realizing the press-fitting process.

[0004] The above patent application discloses that a floating seat structure is used to adjust the press-fit position. However, the structure of the floating seat is not ideal, and the floating spring is directly exposed on the periphery. It is worthwhile to make further improvements to the existing floating structure. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide a floating installation mechanism and a sleeve pressing device, further optimize the structural design of the floating installation mechanism, further improve the stability and reliability of the product, and avoid interference of the external environment on the product.

[0006] The technical solution adopted in the present application is: a floating installation mechanism, including a base and a mounting seat, the mounting seat is connected to the base through a floating assembly, the floating assembly includes a first block seat, a second block seat and a third block seat stacked in sequence, the second block seat is provided with a protrusion 1 embedded in the first block seat, the protrusion 1 is connected to the first block seat through an X-direction spring group, the third block seat is provided with a protrusion 2 embedded in the second block seat, the protrusion 2 is connected to the second block seat through a Y-direction spring group, the third block seat is subjected to force to generate a Y-direction displacement relative to the second block seat, and the second block seat is subjected to force to generate an X-direction displacement relative to the first block seat.

[0007] Compared with the prior art, the advantage of the present application is that, first, a connection is provided between the mounting seat and the base through a floating component. This makes the mounting seat a movable structure relative to the fixed base. The product is installed on the mounting seat, and the frame to be pressed will be fixed through other reference positioning. If the mounting hole of the frame on the mounting seat has no position deviation and is a standard structural part, the mounting seat is not subject to force, and the corresponding floating component is also not subject to force deformation.

By adding a floating component, the present application makes the mounting seat an active mounting seat that can adapt to frame mounting holes with certain deviations.

Specifically, this application sets a protrusion 1 on the second block seat, embeds the protrusion 1 into the first block seat, and sets an X-direction spring group between the protrusion 1 and the first block seat, so that the X-direction spring group is well hidden in the first block seat, avoiding the interference of the external environment on the X-direction spring, and the protrusion 1 is embedded in the first block seat, and the corresponding first block seat will also restrict the protrusion 1, that is, there is a certain restriction on the second block seat, thereby improving the stability and reliability of the second block seat relative to the first block seat when moving. Similarly, the protrusion 2 is embedded in the second block seat, and the Y-direction spring is hidden in the second block seat, which also avoids the interference of the external environment on the Y-direction spring, and improves the stability and reliability of the third block seat relative to the second block seat when moving.

[0030] The present application is described in detail below in conjunction with the accompanying drawings.

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] A floating installation mechanism and a sleeve pressing device, such as Figures 1 to 4 As shown: it includes a base 1 and a mounting seat 2, wherein the mounting seat 2 is connected to the base 1 through a floating component, and the mounting seat 2 and the base 1 are connected through a floating component. This makes the mounting seat 2 a movable structure relative to the fixed base 1. When the product is installed on the mounting seat 2, the frame to be pressed will be fixed through other reference positioning. If the mounting hole of the frame on the mounting seat 2 has no position deviation and is a standard structural part, the mounting seat 2 is not subject to force, and the corresponding floating component is also not subject to force deformation. If the mounting hole of the frame on the mounting seat 2 has a position deviation, the frame will apply force to the mounting seat 2, forcing the floating component to deform, thereby causing the mounting seat 2 to shift relative to the base 1 to adapt to the position of the frame mounting hole. By adding a floating component, the present application makes the mounting seat 2 an active mounting seat 2 that can adapt to the sub-frame mounting hole with a certain deviation.

[0033] The floating assembly includes a first block seat 3, a second block seat 4 and a third block seat 5 stacked in sequence. The second block seat 4 is provided with a protrusion 6 embedded in the first block seat 3. The protrusion 6 is connected to the first block seat 3 through an X-direction spring group 7, and the X-direction spring group 7 is well hidden in the first block seat 3, thereby avoiding interference of the external environment on the X-direction spring. Moreover, the protrusion 6 is embedded in the first block seat 3, and the corresponding first block seat 3 will also restrict the protrusion 6, that is, there are certain restrictions on the second block seat 4, thereby improving the stability and reliability of the second block seat 4 when moving relative to the first block seat 3.

[0034] The third block seat 5 is provided with a second protrusion 8 embedded in the second block seat 4. The second protrusion 8 is connected to the second block seat 4 through a Y-direction spring group 9. The Y-direction spring is hidden in the second block seat 4, which also avoids the interference of the external environment on the Y-direction spring, and improves the stability and reliability of the third block seat 5 when it moves relative to the second block seat 4. The third block seat 5 can generate a Y-direction displacement relative to the second block seat 4 when it is subjected to force, and the second block seat 4 can generate an X-direction displacement relative to the first block seat 3 when it is subjected to force. The relative movement between the three blocks realizes the activity of the mounting seat 2 in the XY plane and realizes the correction of its position.
