Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to a front and rear bushing press-fitting device for an automobile chassis control arm. Background Art

[0002] In the automobile manufacturing industry, the chassis control arm is a key suspension system component, and its quality and performance are directly related to the vehicle's handling stability, safety and comfort. The front and rear bushings of the control arm are important components that connect the control arm to the body or other suspension parts. The press-fit quality directly affects the suspension effect and driving performance of the vehicle.

[0003] Traditionally, the front and rear bushings of automobile chassis control arms are pressed manually or semi-automated, which has problems such as low production efficiency, low pressing accuracy, and high labor intensity for operators. Manual pressing often relies on the operator's experience and feel, and it is difficult to ensure that each bushing can achieve the ideal pressing effect, which increases the quality problems and safety hazards caused by improper pressing.

[0004] In addition, due to the lack of precise mechanical transmission and air pressure control systems, traditional press-fitting equipment is prone to problems such as bushing misalignment, damage or uneven press-fitting during the clamping and press-fitting process. These problems not only affect the performance and life of the control arm, but may also have adverse effects on the entire suspension system, thereby affecting the driving quality and safety of the entire vehicle. Summary of the invention

[0005] In view of the problems existing in the above-mentioned background technology, the present invention patent aims to propose an innovative solution, namely, a front and rear bushing press-fitting device for a vehicle chassis control arm.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a front and rear bushing pressing device for a vehicle chassis control arm, comprising a box body, a first cylinder, a front bushing storage box, a servo motor and a second cylinder, the inner top wall of the box body is fixedly connected with a fixing plate, the fixing plate is penetrated and connected with a movable rod, the bottom of the movable rod is symmetrically fixedly connected with two fixing blocks, the opposite side walls of the two fixing blocks are fixedly connected with chains, the two side walls of the fixing plate are fixedly connected with fixing brackets, the fixing brackets are rotatably connected with movable gears through a rotating shaft, the movable gears are meshed with chains, the shape of the chain is a right angle, the bottom end of the chain is fixedly connected with a movable block, the side wall of the movable block away from the fixing plate is fixedly connected with a front bushing clamping mechanism, the two front bushing storage boxes are symmetrically fixedly connected to the inner rear wall of the box body, the two The front bushing storage boxes are respectively located on both sides of the fixed plate, and the two front bushing clamping mechanisms are located between the two front bushing storage boxes, the first cylinder is fixedly connected to the bottom of the fixed bracket, the movable end of the first cylinder is fixedly connected to a pressing block, and the pressing block is located directly above the front bushing clamping mechanism, the servo motor is fixedly connected to the bottom of the box body, the driving end of the servo motor is fixedly connected to a driving rod, the top of the driving rod is fixedly connected to a material tray, the material tray is located below the front bushing clamping mechanism, the driving rod is connected through a rotating disk, and the top of the rotating disk is distributed with a rear bushing clamping mechanism in a circular array, the rotating disk is located below the material tray, the second cylinder is connected through the bottom of the box body, the driving end of the second cylinder is fixedly connected to a support block, and the support block contacts the bottom of the rotating disk.

[0007] Preferably, a plurality of control arm clamping grooves are formed through the top of the material tray, and the plurality of rear liner clamping mechanisms are respectively located directly above the plurality of control arm clamping grooves.

[0008] Preferably, the two rear liner clamping mechanisms are located directly below the two front liner clamping mechanisms.

[0009] Preferably, the two movable blocks are in contact with two side walls of the fixed plate respectively.

[0010] Preferably, a door is provided on the front wall of the box body.

[0011] Working principle: When a front and rear bushing pressing device of a vehicle chassis control arm is used, the second cylinder drives the support blocks to move toward each other, causing the support blocks to no longer support the rotating disk, causing the rotating disk to move downward, and the servo motor drives the drive rod to drive the material disk and the rotating disk to rotate, so that the operator can clamp the rear bushing of the control arm to the multiple rear bushing clamping mechanisms of the rotating disk in sequence, and then the front bushing storage box stores the front bushing of the control arm, and the control arm clamping groove on the material disk clamps multiple control arms in sequence, and then one of the first cylinders drives the pressing blocks to move toward each other, so that the pressing block drives the front bushing clamping mechanism on the movable block to move downward, causing the chain on the top of the movable block to move, so that the fixed block at the other end of the chain drives the movable rod to move horizontally and linearly, and the other fixed block on the movable rod moves away from the fixed plate. The front bushing clamping mechanism is moved in the direction of the moving block, so that the chain connected to the fixed block pulls the movable block to move upward, so that the front bushing clamping mechanism on the movable block moves to the vicinity of the clamping port of the front bushing storage box, so that the front bushing storage box can clamp the front bushing onto the front bushing clamping mechanism, and then the first cylinder above the front bushing clamping mechanism drives the pressing block to move downward, so that the pressing block pushes the front bushing clamping mechanism with the front bushing clamped thereon to move downward, so that the front bushing on the front bushing clamping mechanism can be pressed onto the top end of the control arm on the material disc, and at the same time, the second cylinder drives the supporting block to move upward, so that the supporting block pushes the rotating disk to move upward, so that the rear bushing clamping mechanism of the rotating disk moves upward, so that the rear bushing in the rear bushing clamping mechanism is pressed onto the bottom end of the control arm, thereby completing the pressing of the front and rear bushings of the control arm. When the movable block moves downward, another movable block moves upward to another front bushing storage box, so that the front bushing clamping mechanism on the movable block can clamp the front bushing. Therefore, the reciprocating up and down movement of the front bushing clamping mechanisms on the two movable blocks can realize the press-fitting of two front bushings in sequence. After the press-fitting of the front and rear bushings of the two control arms is completed, the driving rod can be driven by the servo motor to drive the material plate and the rotating plate to rotate, so that the control arm clamping groove under the front bushing clamping mechanism and the rear bushing clamping mechanism are swapped, which is convenient for replacing the control arm to realize the press-fitting of the front and rear bushings of multiple control arms.

[0012] The present invention provides a front and rear bushing press-fitting device for a vehicle chassis control arm. It has the following beneficial effects: 1. Through the coordinated work of the cylinder and the servo motor, the front and rear bushings of the control arm can be quickly and accurately pressed, which significantly improves production efficiency. The front bushing clamping mechanism on the two movable blocks can move up and down reciprocatingly to realize the sequential pressing of the two front bushings, further improving production efficiency.

[0013] 2. The device adopts precise mechanical transmission and air pressure control system to ensure the stability and accuracy of the bushing during the press-fitting process, reducing quality problems caused by improper press-fitting. The rotating design of the rotating disk and the material disk makes the clamping and press-fitting process of the control arm and bushing smoother, avoiding damage or dislocation caused by improper operation.

[0014] 3. Automated operation greatly reduces the labor intensity of operators and avoids fatigue and risk of misoperation caused by long-term repetitive labor. Operators only need to perform simple clamping and monitoring in the initial stage to realize the automation of the entire press-fitting process. BRIEF DESCRIPTION OF THE DRAWINGS
