Technical Field

[0001] This utility model relates to a device for welding car seat frames. Background Technology

[0002] Existing welding machines for car seat frames are relatively heavy, so they are equipped with locking rollers at the bottom for easy movement and positioning. However, the lifespan of this roller support structure is relatively short. After a period of use, the entire machine will shake, affecting the accuracy of the welding point position. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a welding device for car seat frames.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a car seat frame welding equipment, including a main body, a control box disposed on one side of the main body and four support units disposed below the main body;

[0005] The four support units are located at the four corners below the main body;

[0006] The support unit includes a fixed plate, support feet, a roller unit, and a drive unit disposed above the fixed plate. The fixed plate is disposed below the bottom of the main body. The support feet are disposed on one side of the roller unit. Each support foot includes a screw and a support base. The support base is disposed below the fixed plate via the screw. The roller unit includes a roller, a connector, and a U-shaped frame. The connector is disposed below the fixed plate. The roller is disposed on the connector and is located on one side of the support base. The U-shaped frame is disposed above the fixed plate with its opening facing downwards. A spring is disposed inside the U-shaped frame. One end of the spring is connected to the inner wall of the main body, and the other end of the spring is connected to the bottom of the inner side of the U-shaped frame. The spring is in a compressed state. The lower end of the U-shaped frame passes through the fixed plate and is connected to the connector.

[0007] The drive unit includes a cylinder and a wedge. The cylinder is horizontally positioned, and the wedge is positioned at the top of the cylinder rod. The upper part of the U-shaped frame is provided with a ramp, and the wedge abuts against the ramp of the U-shaped frame. The wedge drives the U-shaped frame to move up and down.

[0008] A limiting mechanism is provided above the wedge block. The limiting mechanism includes a crossbeam, a support rod, and a limiting wheel.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1-3 As shown, a welding device for a car seat frame includes a main body 1, a control box 2 disposed on one side of the main body 1, and four support units disposed below the main body 1.

[0019] The four support units are located at the four corners below the main body 1;

[0020] The support unit includes a fixed plate 7, support feet, a roller unit, and a drive unit disposed above the fixed plate 7. The fixed plate 7 is disposed below the bottom of the main body 1. The support feet are disposed on one side of the roller unit. Each support foot includes a screw 4 and a support base 3. The support base 3 is disposed below the fixed plate 7 via the screw 4. The roller unit includes a roller 5, a connector 6, and a U-shaped frame 8. The connector 6 is disposed below the fixed plate 7. The roller 5 is disposed on the connector 6 and is located on one side of the support base 3. The U-shaped frame 8 is disposed above the fixed plate 7. The opening of the U-shaped frame 8 faces downward. A spring 9 is disposed inside the U-shaped frame 8. One end of the spring 9 is connected to the inner wall of the main body 1, and the other end of the spring 9 is connected to the bottom of the inner side of the U-shaped frame 8. The spring 9 is in a compressed state. The lower end of the U-shaped frame 8 passes through the fixed plate 7 and is connected to the connector 6.

[0021] The drive unit includes a cylinder 10 and a wedge 11. The cylinder 10 is horizontally arranged, and the wedge 11 is located on the top of the cylinder rod. The upper part of the U-shaped frame 8 is provided with a ramp. The wedge 11 abuts against the ramp of the U-shaped frame 8, and the wedge 11 drives the U-shaped frame 8 to move up and down.

[0022] A limiting mechanism is provided above the wedge block 11. The limiting mechanism includes a crossbeam 14, a support rod 12, and a limiting wheel 13. The crossbeam 14 is horizontally arranged above the U-shaped frame 8. The limiting wheel 13 is located above the wedge block 11 and abuts against the wedge block 11. The limiting wheel 13 is arranged at one end of the support rod 12, and the other end of the support rod 12 is connected to the crossbeam 14.

[0023] Preferably, a rubber pad is provided on the lower end surface of the support base 3.

[0024] Preferably, a control box 2 is provided on one side of the main body 1, and a controller is provided inside the control box 2. The cylinder 10 is electrically connected to the controller.

[0025] When movement is required, cylinder 10 drives wedge 11 to move forward, thereby compressing the U-shaped frame 8 and causing it to move downward. In fact, the upper surface of wedge 11 is a plane, and the lower surface is an inclined surface matching the slope of the U-shaped frame 8. Thus, during the movement of wedge 11, the limiting wheel 13 maintains its supporting and limiting function. The downward movement of the U-shaped frame 8 pushes the connecting piece 6 downward, causing the roller 5 to move downward. Finally, the roller 5 contacts the ground, and the support base 3 detaches from the ground, allowing the main body 1 to... It can be moved easily, and during the movement, the limiting wheel 13 always provides stable downward support to the wedge block 11, reducing the lateral stress of the cylinder 10, thereby ensuring the stability of the cylinder 10 structure and improving the service life of the cylinder 10; when it moves to the target position, the cylinder 10 is activated, pulling the wedge block 11, and under the action of the spring 9, pushing the U-shaped frame 8 upward, so that the height of the roller 5 off the ground is greater than that of the support seat 3, thereby allowing the support seat 3 to land and achieve stable support. The screw 4 is set here mainly to facilitate fine adjustment of the height of the support seat 3.

[0026] Compared with the prior art, the equipment for welding the car seat frame uses a cylinder 10 to drive a wedge 11 to lift and lower the roller unit. When movement is required, the lower end of the roller is made to be lower than the horizontal height of the support seat 3, thus enabling the main body 1 to move. When movement is not required, the roller 5 is retracted by the spring 9 to achieve stable support. Furthermore, a limiting mechanism is set to achieve stable support for the wedge 11, thereby improving the stability and service life of the structure.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
