[0002] A control arm, also known as a suspension control arm or suspension arm, is a component used in automobiles, motorcycles, bicycles and other vehicles. A control arm is usually a curved metal member that connects the vehicle's body to the wheel suspension portion. They are located above the wheel and support and control the movement of the wheel by connecting to the wheel assembly and the vehicle's chassis. One of the main functions of the control arm is to ensure that the wheel remains in contact with the road during driving, while also bearing part of the load of the suspension system.

[0003] At present, there is a process in the production of control arms as shown in the attached Figure 3 As shown, the aluminum bracket 2 needs to be press-fitted onto the hydraulic bushing 101 of the main body 1, and the bracket opening 201 of the aluminum bracket 2 is oriented in a fixed direction after installation. The positioning structure in the existing press-fitting device is relatively simple, and each press-fitting device can only correspond to one aluminum bracket 2. When the width of the bracket opening 201 is adjusted, the press-fitting device cannot be used, and the existing press-fitting device lacks guide positioning between the aluminum bracket 2 and the hydraulic bushing 101, which easily leads to press-fitting errors. For this reason, a front control arm welding press-fitting positioning device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2 As shown, a front control arm welding press-fitting positioning device includes a base 3 and a cylinder 5, wherein the base 3 is connected to a mounting seat 4, the cylinder 5 is mounted on the mounting seat 4, the movable end of the cylinder 5 is connected to a fixed plate 6, two symmetrically distributed side plates 7 are connected to the two sides of the fixed plate 6, each of the side plates 7 is connected to an auxiliary arm 8 for positioning the angular direction of the aluminum bracket 2, and a positioning sleeve 13 is coaxially connected to the fixed plate 6.

[0019] In this embodiment, each of the auxiliary arms 8 is provided with two upper and lower symmetrical mounting grooves 9 at one end away from the side plate 7, and each of the mounting grooves 9 is provided with a removable gasket 10. Corresponding threaded holes 11 are provided on the gasket 10 and the mounting groove 9. The gasket 10 is connected to the auxiliary arm 8 through a connecting bolt 12. The two auxiliary arms 8 are respectively used for pressing the aluminum bracket 2 of the left and right control arms.

[0020] In this embodiment, an annular stop plate 15 is coaxially connected to the positioning sleeve 13 , and a guide rod 14 is coaxially connected to one end of the positioning sleeve 13 away from the fixed plate 6 .

[0021] In this embodiment, the end of the positioning sleeve 13 away from the fixing plate 6 is chamfered, and the end of each gasket 10 away from the side plate 7 is chamfered to facilitate the aluminum bracket 2 to be inserted into the positioning sleeve 13.

[0022] In this embodiment, the auxiliary arm 8, gasket 10, positioning sleeve 13, guide rod 14 and abutment plate 15 are all made of stainless steel material. Stainless steel material has good rust resistance and wear resistance and is suitable for the use scenario of the press-fitting device.

[0023] Working process and principle:

[0024] When in use, the aluminum bracket 2 is first inserted into the positioning sleeve 13, and the bracket opening 201 is inserted into the auxiliary arm 8 on one side. The auxiliary arm 8 is used to realize the positioning of the bracket opening 201 when the aluminum bracket 2 is pressed. Then, the cylinder 5 is turned on to push the aluminum bracket 2 forward and approach the fixed main body 1. During the advancement of the aluminum bracket 2, the guide rod 14 will first contact the hydraulic bushing 10 to ensure that the aluminum bracket 2 is aligned with the hydraulic bushing 10, thereby improving the press-fitting accuracy. When the width of the bracket opening 201 changes due to the change in the model of the aluminum bracket 2, the thickness of the gasket 10 on the auxiliary arm 8 can be changed to adapt to bracket openings 201 of different widths, thereby increasing the application range of the press-fitting device and reducing the production cost.
