Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to an adjusting device for a control arm of an automobile chassis part. Background Art

[0002] The automobile chassis control arm, also known as the swing arm, is an important part of the automobile chassis system. It is one of the core components of the automobile suspension system and the direct connection point between the front wheel assembly and the frame. Although it looks simple, the control arm plays a vital role in the overall stability and driving performance of the vehicle. There are many types of control arms, which are usually made of steel, iron or aluminum alloy as the main materials. Steel and iron control arms have strong strength, firmness and resistance to damage, while aluminum alloy control arms are light, corrosion-resistant and have a longer service life. They are more common in high-end models.

[0003] Since most of the control arms are of special shapes, conventional clamping devices cannot adapt well to control arms of different shapes and cannot clamp the control arms well, which makes it difficult to fix the control arms during assembly. When assembling with other parts, problems such as misalignment, installation difficulties or looseness after assembly may occur. This will not only affect the stability and performance of the entire suspension system, but may also cause abnormal vibration or noise in the vehicle during driving. If the control arm cannot be fixed well during processing and assembly, workers may need to spend more time and energy to adjust and fix the parts, which will seriously affect production efficiency. In view of the above problems, an adjustment device for the control arm of an automobile chassis part is proposed to solve them. Utility Model Content

Then, when assembling with other parts, problems such as misalignment, installation difficulties, or looseness after assembly may occur. This will not only affect the stability and performance of the entire suspension system, but may also cause abnormal vibration or noise in the vehicle during driving. If the control arm cannot be fixed well during processing and assembly, then the workers may need to spend more time and energy to adjust and fix the parts, which will seriously affect the production efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: an adjustment device for a control arm of an automobile chassis part, comprising a base plate, a pressure block is fixedly connected to the left side of the upper surface of the base plate by welding, a positioning groove is provided on the upper surface of the base plate and the right side of the pressure block, at least three positioning columns are fixedly connected inside the positioning groove, and the positioning columns are distributed at the three vertices of a triangle, movable slide rails are fixedly connected to the front and rear sides of the middle part of the upper surface of the base plate, sliders are slidably connected to the surfaces of the two movable slide rails, a clamping assembly is arranged above the four sliders, an L-shaped plate is fixedly connected to the rightmost side of the upper surface of the base plate, and a threaded sleeve is fixedly connected to the upper end of the L-shaped plate.

[0006] Preferably, the threaded sleeve is internally threadedly connected to a threaded screw, and the rightmost end of the threaded screw is fixedly connected to a driving handwheel.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] Reference Figure 1-4 As shown, an adjustment device for a control arm of an automobile chassis part comprises a base plate 1, a pressure block 2 is fixedly connected to the left side of the upper surface of the base plate 1 by welding, a positioning groove 3 is provided on the upper surface of the base plate 1 and the right side of the pressure block 2, at least three positioning columns 4 are fixedly connected inside the positioning groove 3, and the positioning columns 4 are distributed at the three vertices of a triangle, movable slide rails 5 are fixedly connected to the front and rear sides of the middle part of the upper surface of the base plate 1, sliders 6 are slidably connected to the surfaces of the two movable slide rails 5, and clamping components 7 are arranged above the four sliders 6, an L-shaped plate 8 is fixedly connected to the rightmost side of the upper surface of the base plate 1, a threaded sleeve 9 is fixedly connected to the upper end of the L-shaped plate 8, and the clamping component 7 can be automatically adjusted to adapt to the surface shapes of different control arms.

[0023] Specifically, the threaded sleeve 9 is internally threadedly connected with a threaded screw 10, and the rightmost end of the threaded screw 10 is fixedly connected with a driving handwheel 11. The threaded screw 10 is in the form of a ball screw, so that the movement of the clamping assembly 7 is more precise.

[0024] It is worth mentioning that the clamping assembly 7 includes a fixed plate 701, the bottom of which is fixedly connected to four sliders 6, an arc-shaped groove 702 is provided inside the fixed plate 701, and clamping columns 704 are slidably connected inside the front and rear ends of the arc-shaped groove 702, and a plurality of balls 703 are arranged between the inside of the arc-shaped groove 702 and the two clamping columns 704. The balls 703 are used for transmission so that the two clamping columns 704 can move in different directions. When the two clamping columns 704 are in contact with the surface of the control arm, compression is formed.

[0025] Specifically, a movable slot 705 is opened through the middle of the two clamping columns 704, and a limiting column 706 is arranged inside the movable slot 705, and the limiting column 706 is fixedly connected to the fixed plate 701. The movable slot 705 can also limit the movement of the clamping column 704 to prevent the clamping column 704 from escaping from the interior of the arc groove 702 and causing the ball 703 to run out.

[0026] Preferably, the left ends of the two clamping columns 704 are fixedly connected with rubber top blocks 707, and the rubber top blocks 707 can prevent the clamping columns 704 from slipping when contacting the surface of the control arm, thereby failing to tighten the control arm well.

[0027] The upper right end of the fixing plate 701 is fixedly connected with a bearing seat 12 , and the interior of the bearing seat 12 is rotatably connected to the left end of the threaded screw 10 .

[0028] Specifically, the right ends of the two movable slide rails 5 are fixedly connected to the limit blocks 13, and the limit blocks 13 limit the movement of the clamping assembly 7 to prevent the clamping assembly 7 from detaching from the movable slide rail 5 when moving to the right, thereby limiting the clamping assembly 7.

[0029] Working principle: When assembling the control arm, first place the control arm in the positioning groove 3 and limit its position through the positioning column 4, then use the driving hand wheel 11 to drive the threaded screw 10 to rotate. Since the threaded sleeve 9 is fixed inside the L-shaped plate 8, the threaded screw 10 will move to the left under the action of the threaded sleeve 9, and then push the fixed plate 701 to move along the movable slide rail 5. Then, when a certain rubber top block 707 contacts the surface of the control arm, the clamping column 704 will push the ball 703 to move inside the arc groove 702, thereby pushing another clamping column 704 to move, and the fixed plate 701 continues to move until the two clamping columns 704 contact the surface of the control arm, squeezing the control arm onto the pressure block 2, and clamping the control arm with an uneven surface.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
