Description

Technical Field

[0001] The utility model relates to the technical field of vehicle processing, and particularly relates to a welding swing device for a front axle assembly of a special vehicle. Background Art

[0002] Special vehicles refer to vehicles that exceed the design vehicle limit in terms of external dimensions, weight, etc. and are for special purposes. They are specially made or modified, equipped with fixed devices and equipment, and their main function is not for carrying people or goods. The front axle assembly of a special vehicle is welded by several components. The weight and volume of the main body of the front axle assembly are relatively large. Therefore, when welding other components to the main body, corresponding devices are needed to assist in positioning and fixing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a welding swing device for a front axle assembly of a special vehicle, which has the effect of facilitating multi-directional welding of the front axle main body components.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: a welding swing device for a front axle assembly of a special vehicle, including a frame, a main shaft is installed on the frame, and a driving device for driving the main shaft to rotate is installed. A fixing plate is fixed at the end of the main shaft. Two upper and lower support plates are fixed on the side of the fixing plate away from the main shaft. A fixing cavity is arranged between the two upper and lower support plates. The support plates are threadedly connected with fixing bolts whose ends extend into the fixing cavity.

[0005] By adopting the above technical solutions, the front axle main body is placed in the fixing cavity, and the front axle main body is fixed between the two upper and lower support plates by using fixing bolts. Then, multiple components on the front axle main body are welded to the front axle main body, improving the convenience of welding work. When carrying out welding work, the driving device drives the main shaft to rotate, thereby driving the front axle main body to rotate to complete multi-directional and multi-angle welding of the front axle main body components, improving the flexibility of welding work.

[0006] The further setting of the utility model is that: the driving device is a driving motor.

[0007] By adopting the above technical solutions, it drives the main shaft to rotate, thereby driving the front axle main body to rotate to complete multi-directional and multi-angle welding of the front axle main body components.

[0008] The further setting of the utility model is that: there are multiple fixing bolts.

[0009] By adopting the above technical solutions, multiple fixing bolts jointly fix the front axle main body between the two upper and lower support plates, improving the welding stability.

[0010] The further setting of the utility model is that: a reinforcing plate is fixed between the side of the support plate away from the fixing cavity and the fixing plate.

[0011] By adopting the above technical solution, the reinforcing plate further supports the bracing plate, improving the stability of the device.

[0012] A further setting of the present utility model is that pressing screws are fixed at the upper and lower ends of the fixing plate, the two bracing plates are located between the pressing screws at the upper and lower ends, and a pressing plate is inserted between the pressing screws at the upper and lower ends.

[0013] By adopting the above technical solution, the pressing plate further restricts and fixes the front axle main body fixed between the upper and lower bracing plates, making the overall fixation of the front axle main body more stable and improving the welding stability.

[0014] A further setting of the present utility model is that notch openings for inserting the pressing screws are provided at the upper and lower ends of the pressing plate, and pressing nuts are threadedly connected to the ends of the pressing screws extending out of the notch openings and are fitted to the pressing plate.

[0015] By adopting the above technical solution, when installing the pressing plate, the ends of the pressing screws at the upper and lower ends extend out from the notch openings at the upper and lower ends of the pressing plate, and the pressing nuts are rotated to make them closely adhere to the pressing plate, thereby fixing the pressing plate between the front axle main body and the pressing nuts. The pressing plate realizes the fixing and limiting of the front axle main body in the horizontal direction, and at the same time, the upper and lower bracing plates realize the fixing and limiting of the front axle main body in the vertical direction. Thus, the front axle main body and the main shaft are finally relatively stably fixed, facilitating the realization of multi-directional stable welding of the front axle main body.

[0016] A further setting of the present utility model is that two pressing screws are provided at the same end of the fixing plate.

[0017] By adopting the above technical solution, the overall fixation of the front axle main body is made more stable.

[0018] The beneficial effects of the present utility model are:

[0019] 1. Place the front axle main body in the fixing cavity, use fixing bolts to fix the front axle main body between the upper and lower bracing plates, and then weld multiple components on the front axle main body to the front axle main body, improving the convenience of welding work;

[0020] 2. When carrying out welding work, the driving device drives the main shaft to rotate, thereby driving the front axle main body to rotate to complete the multi-directional and multi-angle welding of the front axle main body components, improving the flexibility of welding work;

[0021] 3. The pressing plate further restricts and fixes the front axle main body fixed between the upper and lower bracing plates, making the overall fixation of the front axle main body more stable and improving the welding stability. Description of the Drawings
