Description

Technical Field

[0001] The utility model relates to the field of bushing press-fitting, in particular to a guide structure for press-fitting an open bushing. Background Art

[0002] Bushings are a common component in the mechanical manufacturing and automotive industries, often used to reduce friction, absorb vibration, secure position, and guide movement. Steering knuckle bushings, in particular, play a crucial role in automotive suspension systems. They connect the steering knuckle to the vehicle frame, transmitting steering forces while allowing a certain amount of axial and radial movement to accommodate vibration caused by road irregularities. Traditional bushing designs often struggle to meet stringent performance standards, especially under dynamic loads. The multi-directional stability of closed bushings can result in insufficient suspension deformation, leading to reduced chassis performance and passenger comfort. This has led to a demand for open bushings, which exhibit different amounts of deformation in different directions under the same force. Open bushing designs have been proposed, which can, to some extent, address the deformation problem under multi-directional forces and improve suspension system performance. However, the presence of the opening in the outer tube of an open bushing makes it more difficult to control the dimensions, which presents new challenges during the press-fit process. Ensuring precise press-fit while ensuring the multi-directional stability of the open bushing has become a technical challenge. Therefore, designing a tool that can smoothly press open bushings into steering knuckles remains a major technical challenge in this field. Utility Model Content

[0003] The utility model provides a guide structure for pressing an open bushing, which can solve the problem that the existing pressing tooling cannot completely press the open bushing that is one size larger into the steering knuckle, resulting in poor stability and reliability of the rubber surface layer and thus affecting the performance of the entire vehicle.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide structure for pressing an open bushing, comprising a support plate for supporting a steering knuckle of an automobile; a pressure plate, which can be raised and lowered and is arranged directly above the support plate, a guide block for guiding the open bushing into the steering knuckle of the automobile is fixedly arranged in the middle of the pressure plate, a guide hole passing through the middle of the guide block is provided, a guide protrusion is provided on the side wall of the guide hole, the guide protrusion is conical, and the cross-sectional area of the guide protrusion gradually decreases from top to bottom; a top plate, which is arranged above the pressure plate, the top plate is connected to the press, and a pressure head is provided on the lower side of the top plate directly above the guide block. The design of the guide block allows the open bushing to be smoothly pressed into the steering knuckle, preventing the opening direction of the open bushing from rotating significantly during the pressing process.

[0005] Preferably, a positioning protrusion is provided at one end of the support plate for accurate positioning.

[0006] Preferably, the positioning protrusion is provided with a through avoidance hole, which has a simple structure and is convenient for press-fitting.

[0007] Preferably, connecting columns are vertically provided on both sides between the pressure plate and the top plate, the connecting columns are fixedly connected to the top plate, and the connecting columns are slidingly connected to the pressure plate, which has a simple structure and a stable connection.

[0009] Preferably, U-shaped mounting grooves are provided at both ends of the top plate, and the U-shaped mounting grooves are used to connect the top plate to the press.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The structure is simple. By designing a guide block, the bushing can be ensured to be accurately aligned with the steering knuckle during the press-fitting process, reducing the risk of deflection and misalignment and improving the assembly quality. The guide block helps to apply force evenly during the press-fitting process, avoiding deformation or damage of the bushing caused by excessive local pressure, thereby extending the service life of the bushing. It can solve the problem that the existing press-fitting tooling cannot completely press the larger open bushing into the steering knuckle, resulting in poor stability and reliability of the rubber surface layer and thus affecting the performance of the entire vehicle.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-6 As shown, the present invention aims to solve the problem that the existing press-fitting tool cannot completely press the larger open bushing into the steering knuckle, resulting in poor stability and reliability of the rubber surface layer and thus affecting the performance of the entire vehicle. The present invention provides the following technical solutions: a guide structure for press-fitting the open bushing, a support plate 1 for supporting the automobile steering knuckle 6; a press plate 2, which can be raised and lowered and arranged just above the support plate 1, a guide block 3 for guiding the open bushing 7 to enter the automobile steering knuckle 6 is fixedly provided in the middle of the press plate 2, and the middle of the guide block 3 is fixedly provided with a guide block 3 for guiding the open bushing 7 to enter the automobile steering knuckle 6. A guide hole 31 is provided in the top and bottom, and a guide protrusion 32 is provided on the side wall of the guide hole 31. The guide protrusion 32 is conical, and the cross-sectional area of the guide protrusion 32 gradually decreases from top to bottom; a top plate 4 is arranged above the pressure plate 2, and the top plate 4 is connected to the press. A pressure head 8 is provided on the lower side of the top plate 4 just above the guide block 3. The design of the guide block 3 allows the open bushing 7 to be smoothly pressed into the steering knuckle 6, preventing the opening direction of the open bushing 7 from rotating significantly during the pressing process.

[0022] In this embodiment, if Figure 4 As shown, a positioning protrusion 11 is provided at one end of the support plate 1 for accurate positioning.

[0023] In this embodiment, if Figure 4 As shown, the positioning protrusion 11 is provided with a through avoidance hole 12, which has a simple structure and is easy to install.

[0024] In this embodiment, if Figure 1 As shown, connecting columns 5 are vertically provided on both sides between the pressing plate 2 and the top plate 4. The connecting columns 5 are fixedly connected to the top plate 4 and are slidingly connected to the pressing plate 2. The structure is simple and the connection is stable.

[0025] In this embodiment, if Figure 1 As shown, a spring 9 is sleeved on the outer side wall of the connecting column 5 , and the spring 9 abuts against the pressing plate 2 and the top plate 4 , with a simple structure and a stable connection.

When the bottom of the guide block 3 contacts the steering knuckle 6, the pressure plate 2 stops moving, and the top plate 4 continues to drive the pressure head 8 to continue pressing downward. The connecting column 5 slides in the pressure plate 2, and the open bushing 7 moves downward along the guide protrusion 32 and accurately enters the steering knuckle 6; when the open bushing 7 is completely pressed into the steering knuckle 6, the press is stopped to complete the press-fitting operation and the components are reset.
