Description

Technical Field

[0001] This utility model relates to the field of bearing supports, and more specifically to a device for pressing bearing bushings. Background Technology

[0002] In existing technical solutions, when pressing the bushing assembly on the bearing support, there is no dedicated pressing fixture; the bushing is pressed in place solely by a column. Because there is no fixture to secure the bearing support, workers must manually hold the bearing support and column, with the column placed on the pressing surface, and the press head applied to the bearing support for pressing. This method has the following drawbacks:

[0003] 1. Press-fitting operation is relatively dangerous. The bearing support is an eccentric support. When pressing the bushing, one hand must hold the bearing support. The worker can only remove his hand when the bushing is pressed into the support. This press-fitting operation is relatively dangerous and can easily cause injury if not careful.

[0004] 2. It is difficult to align the bushing with the bearing support hole. The interference fit between the bushing and the bearing support hole is large, making it difficult to align the bushing with the support hole during press fitting.

[0005] 3. There is a risk that the bushing may not be pressed in place. The current pressing method is manual, which may result in the staff stopping the pressing process before the bushing is fully pressed in.

[0006] 4. Low efficiency: The existing press-fitting method requires first laying the support flat, then aligning the bushing with the bearing support, and then placing the column on the bushing for press-fitting. The steps are relatively complicated and the operation is difficult. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for pressing bearing bushings, which solves the problems of pressing danger, difficulty in hole alignment, and incomplete bushing pressing, improves efficiency, and optimizes production cycle.

[0008] The purpose of this utility model is achieved through the following technical solution: This device for pressing bearing bushings includes a base plate, a bearing support, and a bushing. A support sleeve and a column are fixed on the base plate. The top of the column is used to place the bushing. The support sleeve has an inner cavity for inserting a connecting block and a spring. The upper end of the connecting block extends out of the inner cavity and connects to a movable block. The spring is set between the lower end of the connecting block and the base plate, allowing the movable block and the connecting block to slide up and down relative to the support sleeve. The bearing support has a positioning hole and a bushing hole. When the bearing support is fitted onto the movable block through the positioning hole, the bushing is precisely aligned with the bushing hole. Under the action of the pressure head, the bearing support moves downward relative to the support sleeve, thus realizing the pressing of the bushing.

[0009] As a further technical solution, the top of the support sleeve has an opening, a step is provided at the connection between the inner cavity and the opening, and a flange is provided at the lower end of the connecting block to cooperate with the step and limit the upward movement of the connecting block.

[0010] As a further technical solution, fixing holes are opened in the center of both the connecting block and the movable block to achieve threaded connection and fixation.

[0011] As a further technical solution, a flange is provided at the bottom of the support sleeve for fixed connection to the base plate.

[0012] As a further technical solution, a positioning protrusion is provided on the top of the column, and the positioning protrusion matches the inner diameter of the bushing.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The movable block is used to position and guide the positioning hole of the bearing support. At the same time, the bushing is aligned with the bushing hole, which solves the problem of no fixed tooling for bushing press-fitting.

[0015] 2. The positions of the bearing support and bushing support device are designed according to the center position of the bearing support and the center position of the bushing press-fit hole, so that the bushing and support can be aligned quickly and easily during press-fitting.

[0016] 3. Adding a spring inside the bearing support device ensures that the downward stroke of the bearing support is greater than the depth to which the bushing is pressed into the bearing support, thus improving the efficiency of bushing pressing and avoiding the quality risk of incomplete pressing.

[0023] The present invention will now be described in detail with reference to the accompanying drawings:

[0024] Example: As attached Figures 1-5 As shown, this device for pressing bearing bushings includes a support sleeve 1, a base plate 2, a movable block 3, a connecting block 4, a column 5, a spring 6, an inner cavity 7, a step 8, a flange 9, an upper opening 10, a bearing support 11, a bushing 12, a positioning hole 13, a bushing hole 14, a flange 15, a fixing hole 16, and a positioning protrusion 17.

[0025] like Figure 1 , 3 As shown, a support sleeve 1 and a column 5 are fixed on the base plate 2. Preferably, the bottom of the support sleeve 1 is provided with a flange 9, and the support sleeve 1 is fixed to the base plate 2 by the flange 9 threaded connection. The top of the column 5 is provided with a positioning protrusion 17, which matches the inner diameter of the bushing 12, so that the bushing 12 can be placed on the top of the column 5 for positioning.

[0026] Reference Appendix Figure 4 The support sleeve 1 has an inner cavity 7 into which a connecting block 4 and a spring 6 are inserted. An upper opening 10 is also provided at the top of the support sleeve 1. A step 8 is provided at the junction of the inner cavity 7 and the upper opening 10. The upper end of the connecting block 4 protrudes from the inner cavity 7 (upper opening 10) and connects to the movable block 3. Preferably, as shown... Figure 5 As shown, both the connecting block 4 and the movable block 3 have fixing holes 16 at their centers for threaded connection. Furthermore, a flange 15 is provided at the lower end of the connecting block 4, which can cooperate with the step 8 to limit the upward movement of the connecting block 4.

[0027] like Figure 3 As shown, spring 6 is positioned between the lower end of connecting block 4 and base plate 2, allowing movable block 3 and connecting block 4 to slide up and down relative to support sleeve 1. Figure 2 As shown, a positioning hole 13 and a bushing hole 14 are provided on the bearing support 11. Preferably, the positions of the support and bushing support device are designed according to the center positions of the bearing support and the bushing press-fit hole, ensuring that when the bearing support 11 is fitted onto the movable block 3 through the positioning hole 13, the bushing 12 is precisely aligned with the bushing hole 14. Under the action of the pressure head, the bearing support 11 moves downward relative to the support sleeve 1, realizing the press-fit of the bushing 12. The presence of the spring 6 ensures that the downward stroke of the bearing support 11 is greater than the depth to which the bushing 12 is pressed into the bearing support 11.

[0028] The working process of this utility model:

[0029] Before press-fitting, select a suitable support sleeve 1 according to the product model (i.e., the specification of bearing support 11). Use flange 9 to thread-connect and fix support sleeve 1 to base plate 2. Install spring 6 and connecting block 4 into the inner cavity 7 of support sleeve 1. Fix connecting block 4 to movable block 3 through fixing hole 16. During press-fitting, first place bushing 12 on column 5 and position it using positioning protrusion 17. Then, use positioning hole 13 to fit bearing support 11 onto movable block 3, at which point bushing 12 is aligned with bushing hole 14. Subsequently, start the press head of external press-fitting equipment. Under the action of the press head, bearing support 11 moves downward relative to support sleeve 1, achieving press-fitting of bushing 12. The presence of spring 6 ensures that the downward stroke of bearing support 11 is greater than the depth to which bushing 12 is pressed into bearing support 11, ensuring proper press-fitting.

[0030] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
