Description

Technical Field

[0001] This utility model relates to the field of bending technology in the production of automotive control arms, specifically to a high-efficiency production device for automotive control arms. Background Technology

[0002] As a guiding and force-transmitting element of the automobile suspension system, the control arm is used to transmit various forces acting on the wheels to the vehicle body, while ensuring that the wheels move along a certain trajectory. When producing control arms, a high-efficiency production device for automobile control arms is required.

[0003] For example, a bending device for manufacturing automotive control arms, authorized by publication number "CN 219786158 U", uses a first gear and a second gear meshing to drive the second gear to rotate, causing a screw to rotate. As the screw rotates, a second support block rises and falls along the screw, causing the top seat to descend and press the pressure block into the bending groove, thereby bending the control arm within the bending groove. The overall mechanism is simple and easy to use, and it can bend two control arms simultaneously, improving work efficiency. However, the device has a poor fixing effect when fixing the automotive control arm, increasing its operational limitations. When bending the automotive control arm to different degrees, different bending heads need to be replaced, reducing the device's work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of unstable fixing of the vehicle control arm, which reduces the bending quality of the device, and the need to replace different bending heads when bending the vehicle control arm to different degrees, which reduces the working efficiency of the device. Therefore, this invention proposes a high-efficiency production device for vehicle control arms.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an efficient production device for automotive control arms, including a housing and a fixed housing. The fixed housing is fixedly connected to the middle of the upper end of the housing. The fixed housing is equipped with a fixing device inside. A support plate is fixedly connected to the rear side of the upper end of the housing. A top plate is fixedly connected to the upper end of the support plate. A hydraulic cylinder is fixedly connected to the inner wall of the top plate. A replacement device is provided below the extension end of the hydraulic cylinder.

[0007] Preferably, the fixing device includes a first bevel gear and a second bevel gear. The rotating shaft of the first bevel gear is rotatably connected to the fixing box through a bearing. The first bevel gear meshes with the second bevel gear. The rotating shaft of the second bevel gear is fixedly connected to a frame. The inner wall of the upper end of the frame is threadedly connected to a threaded rod. The bottom end of the threaded rod is rotatably connected to a clamping plate through a bearing. A roller is installed at the lower end of the clamping plate.

[0008] Preferably, the second bevel gear rotating shaft is rotatably connected to the fixed box via a bearing, and a roller is installed at the bottom of the inner wall of the frame.

[0009] Preferably, the bottom end of the housing is fixedly connected to the base.

[0010] Preferably, the replacement device includes a housing and a fixing rod. The top of the housing is fixedly connected to the telescopic end of the hydraulic cylinder. The fixing rod is fixedly connected to the inner wall of the housing. The outer wall of the fixing rod is slidably connected to the slide plate. The outer wall of the slide plate is fixedly connected to a sliding rod. A locking block is fixedly connected to the outer side of the slide plate. A spring is provided on the inner side of the slide plate. The two ends of the spring are fixedly connected to the two slide plates respectively.

[0011] Preferably, the two ends of the slide plate are slidably connected to the outer shell, the outer wall of the slide rod is slidably connected to the outer shell, the outer wall of the locking block is inserted into the bending head, and the outer wall of the bending head is slidably connected to the outer shell.

[0012] The present invention proposes a high-efficiency production device for automotive control arms, which has the following advantages: Through the cooperation of the fixing device and the fixing box, the operator places the automotive control arm inside the frame, rotates the threaded rod, and causes the threaded rod to drive the clamping plate to move downward. The clamping plate drives the roller to contact the automotive control arm and press against it to fix it. The extension end of the hydraulic cylinder is controlled to move the bending head downward. After the bending head contacts the automotive control arm, it presses against it and bends it. During the bending process of the automotive control arm, the frame rotates with the bending angle of the automotive control arm. By moving inward synchronously with the bending tilt angle of the automotive control arm, the frame provides movement space during the bending process of the automotive control arm. The frame can rotate with the bending angle of the automotive control arm, reducing the limitations of the operation.

[0013] By coordinating the replacement device and the bending head, when the bending head needs to be replaced, the operator holds the sliding rods on both sides and moves them inward. The sliding rods drive the sliding plate and the locking block to move inward synchronously. The sliding plate compresses the spring. Under the restriction of the fixed rod and the outer shell, the sliding plate moves horizontally. When the locking block is no longer engaged with the bending head, the operator pulls the bending head out of the outer shell and replaces it with a new bending head. The operator releases the sliding rods, and under the reaction force of the spring, pushes the sliding plates on both sides to move outward. The movement of the sliding plates drives the locking block to move synchronously, so that the locking block engages with the bending head and fixes the bending head. By using the sliding plate to drive the locking block to engage with the bending head, the operator can control the rapid disassembly and replacement of the bending head, making it more efficient and improving work efficiency.

[0026] See attached document Figure 1-3 6 and 7: The replacement device 3 includes a housing 301 and a fixing rod 302.

[0027] Working principle:

[0028] The fixed bending process of the car control arm:

[0029] The operator places the car control arm inside the frame 204, rotates the threaded rod 205, causing the threaded rod 205 to drive the clamping plate 206 downward. The clamping plate 206 drives the roller 203 to contact the car control arm and press against it to fix it. The extension end of the hydraulic cylinder 7 is controlled to extend and drive the bending head 9 downward. The bending head 9 contacts the car control arm and presses against it to bend it. During the bending process of the car control arm, the frame 204 rotates with the bending angle of the car control arm. At the same time, under the action of the roller 203, the car control arm will have room to move during deformation. At the same time, under the action of the first bevel gear 201 and the second bevel gear 202, the two side frames 204 rotate inward with the car control arm. After the bending is completed, the above process is reversed to remove the car control arm and complete the fixing process of the car control arm.

[0030] The bending process of the car control arm:

[0031] The extension end of the control hydraulic cylinder 7 extends, causing the bending head 9 to move downward. After the bending head 9 contacts the vehicle control arm, it presses against it and bends it. During the bending process of the vehicle control arm, the frame 204 rotates according to the bending angle of the vehicle control arm. After the vehicle control arm is bent, the extension end of the control hydraulic cylinder 7 shortens, causing the bending head 9 to move upward and return to its original position.

[0032] The process of replacing a folding elbow:

[0033] When the bending head 9 needs to be replaced, the operator holds the sliding rods 304 on both sides and moves them inward. The sliding rods 304 drive the sliding plate 303 and the locking block 305 to move inward synchronously. The sliding plate 303 compresses the spring 306. The sliding plate 303 moves horizontally under the restriction of the fixing rod 302 and the outer shell 301. When the locking block 305 is no longer inserted into the bending head 9, the operator pulls the bending head 9 out of the outer shell 301 and replaces it with a new bending head 9. The operator releases the sliding rods 304, and under the reaction force of the spring 306, pushes the sliding plates 303 on both sides to move outward. The sliding plate 303 moves at the same time, driving the locking block 305 to move synchronously, so that the locking block 305 is inserted into the bending head 9 and fixed to the bending head 9. By controlling the rapid disassembly and replacement of the bending head 9, the replacement process of the bending head is made more efficient.
