Technical Field

[0001] The utility model relates to the field of welding of vehicle rotating chassis brackets, and more specifically, it relates to a welding tool for vehicle rotating chassis brackets. Background Art

[0002] The vehicle rotating chassis bracket is one of the important components of a vehicle. It is usually made of high-strength metal materials and has the characteristics of being strong and durable. Its main function is to provide stable support for the vehicle chassis and at the same time be able to rotate at a certain angle, thus playing a key auxiliary role during vehicle driving, steering, etc. When the vehicle is driving, the rotating chassis bracket can withstand various impact forces and vibrations from the road surface, ensuring the stability and safety of the vehicle. When steering, it can cooperate with the steering system to enable the vehicle to smoothly change the driving direction and improve the handling performance. In addition, the design of the rotating chassis bracket also takes into account the overall weight distribution and center of gravity balance of the vehicle, which helps to optimize the performance of the vehicle.

[0003] There is a key process in the production of vehicle rotating chassis brackets to install four lugs on a large ring. The current fixing method (fixture fixing) has some problems. When fixing the lugs (here the lugs are also called lifting lugs) for subsequent welding operations, due to the special shape of the lugs. Generally speaking, special-shaped lugs may have irregular angles, which makes it difficult for them to fit perfectly with the tooling. When the workpiece cannot fit well with the tooling, it is difficult to ensure the position accuracy and stability of the lugs during the welding process. Failing to meet the welding requirements means that problems such as inaccurate welding position, insufficient welding strength, and poor weld quality may occur, which will affect the overall structural strength and reliability of the vehicle rotating chassis bracket.

[0004] Therefore, in order to solve the above technical problems, this application proposes a welding tool for vehicle rotating chassis brackets. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a welding tool for vehicle rotating chassis brackets.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A welding tool for vehicle rotating chassis brackets, including a fixing component, the fixing component includes a disc base, and a support ring located on the disc base, and the two are fixed through a connecting frame. A baffle is fixedly connected below the support ring. A pressing plate is installed on the disc base, and the pressing plate is pressed down by a pressing bolt. U-shaped clamps are installed at the top of the support ring and on both sides of the baffle

[0007] Preferably, a positioning pin A is provided at a position near the edge of the top end of the disc base, and a positioning pin B is provided at the top end of the support ring, so that the two can quickly find their installation positions.

[0008] Preferably, a cushion block is fixedly connected to the pressing part of the pressing plate to prevent indentation on the product.

[0009] Preferably, a rotary driving device is installed on one side of the fixing component, which is driven by a turntable, and a rotary support shaft is installed on the other side of the fixing component to perform welding operations more comprehensively.

[0010] Preferably, a speed reducer is installed on the rotary driving device, and the speed reducer can make the rotation speed of the fixing component slow and stable.

[0011] Preferably, the bottom ends of the rotary driving device and the rotary support shaft are both fixedly connected to a bottom plate through a support frame, and the whole tooling is installed through the two bottom plates.

[0012] Preferably, the pressing plate and the disc base are rotatably connected through a bearing. In this way, when placing the large ring, the pressing plate can be rotated to the side to avoid blocking the smooth placement of the large ring.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the large ring is first placed on the disc base. After the placement is completed, the pressing plate is rotated to directly above the large ring, and then the pressing bolt is tightened to press down the pressing plate, so as to fix the large ring on the disc base. Then, the four lugs are placed against the baffle. The top end of the lug is in contact with the top end of the support ring, and its body is in contact with the baffle. Then, the lugs are tightly fixed by the top end of the support ring and the U-shaped clamps on both sides of the baffle respectively. Later, welding operations can be performed on the lugs and the large ring. The U-shaped clamp has a specific shape and a clamping force application method. Its U-shaped structure can clamp against the surface of the lug, so that it can flexibly adapt to workpieces of different shapes, and the fixation can meet the requirements of welding, thus solving the problem in the background technology that it is difficult to ensure the position accuracy and stability of the lugs during the welding process;

[0015] 2. The utility model can control the rotary driving device by rotating the turntable. The rotary driving device drives the rotation of the fixing component, and the other end of the fixing component is rotationally supported by the rotary support shaft to adjust the welding angle of the lugs, so as to perform welding operations more comprehensively;

[0016] 3. The utility model can make the rotation speed of the fixing component slow and stable through the speed reducer, so as to accurately adjust the welding angle. Description of the Drawings

Specific embodiments

[0023] As Figures 1-3 shown, the present utility model provides a welding tooling for a vehicle rotating chassis bracket, including a fixing component. The fixing component includes a disc base 1 and a support ring 2 located on the disc base 1, and the two are fixed through a connecting frame 18. A baffle 3 is fixedly connected below the support ring 2. A pressing plate 4 is installed on the disc base 1, and the pressing plate 4 is pressed down by a lower pressing bolt 5. U-shaped clamps 6 are installed at the top of the support ring 2 and on both sides of the baffle 3. The pressing plate 4 and the disc base 1 are rotatably connected through a bearing.

[0024] The rotary chassis bracket welded by the utility model comprises four lugs 16 and a large ring 15. First, place the large ring 15 on the disc base 1. After placement, rotate the pressing plate 4 to directly above the large ring 15, and then tighten the downward pressing bolt 5 to press down the pressing plate 4, thereby fixing the large ring 15 on the disc base 1. Then place the four lugs 16 against the baffle 3. The top of the lug 16 is in contact with the top of the support ring 2, and its body is in contact with the baffle 3. Then, press and fix the lugs 16 through the top of the support ring 2 and the U-shaped clamps 6 on both sides of the baffle 3 respectively. Later, welding operations can be performed on the lugs 16 and the large ring 15. The U-shaped clamp 6 has a specific shape and clamping force application method. Its U-shaped structure can clamp the surface of the lug 16, so as to flexibly adapt to workpieces of different shapes. In this case, since the shape of the lug 16 is irregular and it is difficult to fit with the tooling through conventional fixing methods, the U-shaped clamp 16 can be adaptively designed according to the specific shape and position of the lug 16, so that the workpiece can fully fit with the underlying support tooling, making the fixing meet the requirements of welding.

[0025] Furthermore, a positioning pin A7 is provided at the top of the disc base 1 near the edge, and a positioning pin B8 is provided at the top of the support ring 2. Before the pressing plate 4 and the U-shaped clamp 6 fix the large ring 15 and the lugs 16, first limit the position through the positioning pin A7 and the positioning pin B8, so that the two can quickly find their installation positions, which is more convenient for the staff to perform the fixing operation. A cushion block 9 is fixedly connected to the downward pressing part of the pressing plate 4, that is, when the pressing plate 4 presses and fixes the large ring 15, the cushion block 9 contacts the large ring 15 to prevent indentations from being left on the product.

[0026] It should be noted that the positioning method of the positioning pin A7 is to limit the position through the through hole on the large ring 15, while the positioning pin B8 positions the top of the hanging ear by pressing against the side of the hanging ear.

[0027] Moreover, a rotary driving device 10 is installed on one side of the fixing component, which is driven by a turntable 11. A rotary support shaft 12 is installed on the other side of the fixing component. A speed reducer 17 is installed on the rotary driving device 10. The bottoms of the rotary driving device 10 and the rotary support shaft 12 are both fixedly connected to a bottom plate 14 through a support frame 13.

[0028] In use, first fix the two bottom plates 14 in appropriate areas (the areas cooperating with the welding device), and then the operation of fixing the large ring 15 and the lug 16 on the fixing component can be carried out. During the welding process, the rotary drive device 10 can be controlled by rotating the turntable 11. The rotary drive device 10 drives the rotation of the fixing component, and the other end of the fixing component is rotationally supported by the rotary support shaft 12 to adjust the welding angle of the lug 16, so as to perform the welding operation more comprehensively. Moreover, a speed reducer 17 is installed on the rotary drive device 10, and through the speed reducer 17, the rotation speed of the fixing component can be made slow and stable, so that the welding angle can be accurately adjusted.

[0029] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the description shown in the accompanying drawings of the specification and the above description; however, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above, such as minor modifications, decorations and evolutions, are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
