[0002] In the field of valve application, the bushing is inside the valve cover, and generally uses corrosion-resistant materials such as polytetrafluoroethylene or graphite for sealing. The automobile control arm bushing is installed on the McPherson suspension control arm. Its main function is to reduce shock and noise, which plays an important role in the operational stability of the vehicle. It is necessary to improve the traditional automobile control arm bushing to improve its shock reduction, noise reduction and durability. Therefore, the existing method is to add a damping groove 34 in the automobile control arm bushing 8 and insert a rubber member 7 into the damping groove 34. This undoubtedly increases the complexity of installation. The current installation method is to first fix the automobile control arm bushing 8 on a fixture, and then expand the damping groove 34 by holding a specific tool in one hand, and then insert the rubber member 7 into the damping groove 34. This method is easy to damage the inside of the automobile control arm bushing 8 due to the use of tools, and it is relatively inconvenient to expand the damping groove 34, so it affects the work efficiency, the force is easy to be not controlled in place, and it is easy to damage the automobile control arm bushing 8, resulting in a high scrap rate of the automobile control arm bushing 8, so it needs to be improved.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-3 As shown, a bushing assembly tool disclosed in this embodiment includes an upper mounting plate 1, a sliding plate 2, a mold core 3, a sliding rod 4, a lower mounting plate 5 and a lower mold 6, the mold core 3 is vertically connected to the sliding plate 2, a U-shaped arc surface 33 is arranged on the lower mold 6, both sides of the U-shaped arc surface 33 are openings, the sliding rod 4 is fixed to one side of the top of the lower mounting plate 5, the upper part of the sliding plate 2 is fixedly connected to the upper mounting plate 1, the lower part of the sliding plate 2 is slidably connected to the sliding rod 4, and there is a gap between the sliding plates 2 and the sliding plates 2, and there is a gap between the bottom of the sliding plate 2 and the top of the lower mounting plate 5, the mold core 3 is arranged parallel to the inner bottom surface of the U-shaped arc surface 33, and a positioning platform 301 that is against the inner wall of the automobile control arm bushing 8 is arranged at the connection between the mold core 3 and the sliding plate 2.

[0022] Preferably, the upper mounting plate 1 and the sliding plate 2 are fixed by bolts 9 .

[0023] Preferably, the mold core 3 is embedded in the sliding plate 2 and is integrated with the sliding plate 2 .

[0024] Preferably, there is a 7 mm gap between the sliding plates 2, which can prevent the flange portion 35 of the automobile control arm bushing 8 from being damaged when pressing the automobile control arm bushing 8; there is a 10 mm gap between the bottom of the sliding plate 2 and the top of the lower mounting plate 5 to allow the sliding plate 2 to move up and down.

[0025] Preferably, in order to facilitate the insertion of the automobile control arm bushing 8, the end of the mold core 3 away from the sliding rod 4 is provided with a curved surface 31. In this embodiment, by adding the curved surface 31, it is ensured that the automobile control arm bushing 8 is convenient to enter when inserted from the front end of the mold core 3.

[0026] In this embodiment, the upper mounting plate 1 and the sliding plate 2 are fixed together with two bolts, and the mold core 3 is embedded in the sliding plate 2 to prevent the mold core 3 from loosening or falling off during operation. In addition, the sliding rod in this embodiment adopts two positioning pins, which are threadedly connected to the upper mounting plate 1, and the upper part of the positioning pin is slidably connected to the sliding plate 2;

[0027] When it is necessary to assemble the rubber part 7, put the inner diameter of the automobile control arm bushing 8 into the mold core 3, and ensure that the flanged part 35 of the automobile control arm bushing 8 faces the sliding plate 2 and fits with the sliding plate 2. It should be noted here that during the primary installation, it is necessary to prevent the outer diameter of the automobile control arm bushing 8 from being pressed into the U-shaped arc surface 33 of the lower mold 6, thereby damaging the flanged part 35; the flanged part 35 of the automobile control arm bushing 8 fits with the sliding plate 2 surface and also plays a limiting role; then press the upper mounting plate 9, and when the sliding plate 2 is pressed downward, the mold core 3 is driven to descend, so that the automobile control arm bushing 8 is lowered, and the gap at the damping groove 34 above is increased to allow the rubber part 7 to be placed in it; Note: Before the rubber part 7 is inserted into the damping groove 34, a layer of lubricating oil needs to be applied to the surface of the rubber part 7 to make it easier for the rubber part 7 to be placed in the damping groove 34 of the automobile control arm bushing 8 After assembly, the sliding plate 2 is reset, the automobile control arm bushing 8 is separated from the arc surface 31, and finally the automobile control arm bushing 8 is taken out, and the assembly is repeated. Therefore, the structure is provided with a core 3 that can move up and down. When the core 3 is pressed down, the damping groove 34 in the automobile control arm bushing 8 is expanded, and there is no need to slowly expand the damping groove 34 with professional tools in hand, and finally the rubber part 7 is quickly inserted into the expanded damping groove 34, which further improves the work efficiency and makes the operation more convenient. Moreover, no tools are required, thereby reducing the scrap rate. In the later stage, the structure can cooperate with the manipulator and the cylinder. The manipulator first grabs the automobile control arm bushing 8 and puts it into the core 3, and then the cylinder is connected to the upper mounting plate 1, driving the upper mounting plate 1 to move downward, and the manipulator grabs the rubber part 7 and inserts it into the expanded damping groove 34, further improving the work efficiency.
