Description

Technical Field

[0001] The present application relates to the field of press-fitting of automobile bushings, and in particular to a gasket inserting device for bushings. 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] The bushing can absorb and reduce the vibration and bumps generated during the driving of the car through the characteristics of its elastic material, provide a smooth suspension effect, and make the vehicle more comfortable and stable during driving. As the car is driving, the suspension system of the car will make some noise. The shock-absorbing bushing can reduce this noise by reducing the friction and vibration with the ground, providing a quieter riding environment. The shock-absorbing bushing provides appropriate elasticity, which can effectively control the posture adjustment of the car during acceleration, braking and turning, and improve driving stability and safety.

[0004] At present, bushings are mostly installed by press fitting. Relevant prior art, such as the Chinese patent application "A Sub-frame Press Fitting Equipment", application number: CN202311296497.1, 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 sub-frame, and a floating seat. The sub-frame is installed on the servo rotating platform and fixed by the pressing assembly. The mounting hole of the sub-frame 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 presses the bushing into the mounting hole of the sub-frame. The floating seat is provided to adapt to the sub-frame mounting hole with a certain deviation; the rotating platform is provided to rotate the bushing and the sub-frame to the press fitting position to cooperate to realize the press fitting process.

[0005] However, the bushing structure involved in this application is as follows Figure 1 As shown, there is a gap between the base plate of the bushing mounting frame and the outer shell. If a stamping device is used directly for press-fitting, the force on the mounting base plate will only come from the transmission of the bushing inner core. The outer shell and the inner core are connected by a rubber member, and the outer shell is equivalent to being subjected to force alone. This may cause the outer shell to move downward and press on the base plate of the mounting frame, and the two are subjected to force and partially squeezed and deformed. The relative displacement is even too large, causing the outer shell to fall off. Therefore, the current bushing press-fitting opportunities have certain limitations. In this regard, the present application designs a bushing gasket insertion device to insert the gasket into the gap in the bushing to assist in the subsequent press-fitting of the bushing. Utility Model Content

[0006] The technical problem to be solved by the present application is to provide a gasket insertion device for a bushing, which fills the gap of the bushing by inserting the gasket into the bushing to balance the force during press-fitting.

[0007] The technical solution adopted in the present application is: a gasket insertion device for a bushing, comprising a frame and at least one gasket module installed on the frame, wherein the gasket module is connected to the frame through a driving assembly, and the driving assembly drives the gasket module to move when it is operated, and the gasket module comprises a mounting plate connected to an air pump, and the air pump picks up the gasket through the mounting plate when it is operated, and the gasket loses power when the air pump is depressurized.

[0008] Compared with the prior art, the advantage of the present application is that it fully considers the structural characteristics of the bushing and adds a gasket that is adapted to the bushing. The gasket is inserted into the gap of the bushing through the device of the present application to fill the gap of the bushing. Then, when the bushing is pressed later, the bushing can be balanced, and the problem of extrusion deformation or even falling off of the bushing can be solved. Specifically, the present application sets a frame as a base for installing the plug module, and then a driving assembly is connected to the frame, and the plug module is driven by the driving device to move, so as to move the gasket to a suitable position and insert it into the bushing. More specifically, the plug module in the present application includes a mounting plate connected to an air pump. When the air pump is working, it provides power for the mounting plate to pick up the gasket, so that the gasket can be adsorbed on the mounting plate and move with the plug module. After the air pump is depressurized, the gasket loses its adsorption force, and the gasket will move with the bushing to complete the press-fitting of the bushing.

[0009] In some embodiments of the present application, a frame and at least one plug module installed on the frame are included, wherein the plug module is connected to the frame via a driving assembly, and the driving assembly drives the plug module to move. The plug module includes a mounting plate connected to an air pump, and when the air pump is working, the mounting plate picks up the gasket, and when the air pump is depressurized, the gasket loses power.

[0010] In some embodiments of the present application, the driving assembly includes a vertical driving cylinder, a horizontal driving cylinder, a lifting plate and a movable plate. The driving shaft of the vertical driving cylinder is connected to the lifting plate, the horizontal driving cylinder is installed on the lifting plate, and the driving shaft of the horizontal driving cylinder is connected to the movable plate. The vertical driving cylinder drives the lifting plate, the horizontal driving cylinder and the movable plate to move up and down synchronously when it works, and the horizontal driving cylinder drives the movable plate to move when it works.

[0011] In some embodiments of the present application, guide posts are passed through the corners of the lifting plate, and the guide posts are arranged parallel to the drive shaft of the vertical drive cylinder. The moving track of the lifting plate is limited by the guide posts to ensure the stability of its movement.

[0012] In some embodiments of the present application, the plug module includes a floating component, and the floating component includes a support seat and a protruding piece. The support seat is a vertically arranged U-shaped structure, and a slide rail is arranged on the inner bottom surface of the support seat along the vertical direction. The protruding piece is installed on the slide rail. The support seat includes an upper support plate and a lower support plate respectively located above and below the slide rail. The protruding piece moves on the slide rail under force and is limited by the upper support plate and the lower support plate.

[0013] In the present application, a floating assembly is used to provide the gasket with a floating connection state, wherein the upper abutment plate and the lower abutment plate also play a role in limiting the movement trajectory of the protruding member.

[0014] In some embodiments of the present application, an elastic member is provided between the protruding member and the upper abutment plate, and an elastic member is provided between the protruding member and the lower abutment plate. The elastic member applies force to the protruding member so that the protruding member is located in the middle of the slide rail.

[0015] The elastic members located above and below the protruding member exert opposite forces on the protruding member, so that the protruding member is in a floating state, and can have an up and down floating adjustment displacement according to the force applied to the gasket when the gasket is inserted, so that the gasket can adapt to the installation environment of the bushing and be smoothly inserted into the bushing. Preferably, the elastic member can be a spring in a compressed state.

[0016] In some embodiments of the present application, the protruding member is a horizontally placed T-shaped block structure, and the protruding member includes a vertically arranged block one and a horizontally arranged block two, block two is arranged perpendicular to block one and is located in the middle of block one, block one is installed on the slide rail, and block two is connected to the mounting plate.

[0017] In the present application, a surface of the block constitutes abutment surface, which can limit the position of the gasket.

[0018] In some embodiments of the present application, block two is provided with a channel, the bottom surface of the protruding piece is provided with a hollow mounting plate, channels are provided at corresponding positions of the protruding piece and the mounting plate, the channel is connected to the air pump, and when the air pump is working, the gasket can be adsorbed and adhered to the bottom surface of the mounting plate.

[0019] In this application, the optimal solution is to use an air pump, a channel, and a hollow mounting sheet to pick up, move, and release the gasket. The gasket is picked up and released by air pressure, so that the gasket can be easily released after being inserted into the bushing, directly cooperating with the subsequent bushing press-fitting process, and avoiding interference with the mechanical structure of picking up the gasket.

[0020] In some embodiments of the present application, the bottom surface of the protruding piece is connected to the mounting plate via a rotating cylinder, and the rotating cylinder drives the mounting plate to rotate. The mounting plate adopts a hollow structure and is connected to an air pump. When the air pump is working, the gasket can be adsorbed and adhered to the bottom surface of the mounting plate.

[0021] The above structure enables the mounting plate to pick up two or more gaskets at the same time, and to switch different gaskets through the rotating cylinder to insert the bushing.

[0022] In some embodiments of the present application, a rear plug sheet module and two side plug sheet modules are installed on the frame, and the two side plug sheet modules are symmetrically arranged on both sides of the rear plug sheet module.

[0023] In some embodiments of the present application, the angle between the side plug sheet module and the rear plug sheet module is an acute angle, and the side plug sheet module and the rear plug sheet module pick up corresponding gaskets respectively, and the three gaskets form a closed structure.

[0024] That is, the above structure makes the three plug modules on the frame concentrate toward the rear side of the bushing, and makes the front side of the bushing have a large area without interference, which can well cooperate with the installation of the frame, the press-fitting of the bushing and other equipment to avoid interference between equipment.

DETAILED DESCRIPTION

[0033] The present application is described in detail below in conjunction with the accompanying drawings.

[0034] 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.

[0035] A bushing gasket inserting device, embodiment 1 is as follows Figures 2 to 3 As shown: it includes a frame 31 and at least one plug module installed on the frame 31. The plug module is connected to the frame 31 through a driving component. The driving component drives the plug module to move, so as to move the gasket 33 to a suitable position and insert it into the bushing. The plug module includes a mounting plate 32 connected to the air pump. When the air pump is working, the gasket 33 is picked up by the mounting plate 32. When the air pump is depressurized, the gasket 33 loses power. When the air pump is working, the mounting plate 32 is provided with power to pick up the gasket 33, so that the gasket 33 can be adsorbed on the mounting plate 32 and move with the plug module. After the air pump is depressurized, the gasket 33 loses its adsorption force, and the gasket 33 will move with the bushing to complete the press-fitting of the bushing.

[0036] The present application fully considers the structural characteristics of the bushing and adds a gasket 33 adapted to the bushing. The gasket 33 is inserted into the gap of the bushing by the device of the present application to fill the gap of the bushing. Then, when the bushing is subsequently pressed, the bushing can be subjected to balanced force, solving the problem of bushing extrusion deformation or even falling off.

The side plug module 35 and the rear plug module 34 pick up the corresponding gaskets 33 respectively, and the three gaskets 33 form a closed structure. That is, the above structure makes the three plug modules on the frame 31 concentrate toward the rear side of the bushing, and the front side of the bushing is free of interference in a large area, which can well cooperate with the installation of the frame, the press-fitting of the bushing and other equipment settings.
