Description

Technical Field

[0001] The utility model relates to the technical field of vehicle axle clamps, in particular to a welding clamp used for vehicle axle processing. Background Art

[0002] The car axle (also called the axle) is connected to the frame (or load-bearing body) through the suspension, with wheels installed at both ends. The function of the axle is to bear the load of the car and maintain the normal driving of the car on the road. The axle can be integral, like a huge barbell, with the body supported by the suspension system at both ends. Therefore, the integral axle is usually used with non-independent suspension; the axle can also be disconnected, like two umbrellas inserted on both sides of the body, and then each supports the body through the suspension system, so the disconnected axle is used with independent suspension.

[0003] As a key component of a car, the axle bears the weight of the car and various forces during driving. Therefore, the welding quality of the axle must be guaranteed to ensure its strength and durability. The welding process melts the material at high temperature and realizes the connection. For a component like the axle that needs to withstand complex stresses, the quality and performance of the welded joint are crucial. During the welding process, a clamp is required to fix the axle. However, most of the existing axle processing welding clamps do not have the suction function during use. The harmful gases generated by welding can easily affect the surrounding environment and cause harm to the surrounding workers, which is not conducive to the use of axle welding processing. Utility Model Content

[0004] In view of the deficiencies of the existing technology, the utility model provides a welding fixture for axle processing, which solves the problem that the axle processing welding fixture does not have an air suction function during use, and the harmful gases generated by welding easily affect the surrounding environment.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a welding fixture for axle processing, comprising a receiving box, a protective cover with one side open fixedly connected to the top of the receiving box, a cavity defined within the protective cover, a plurality of dust suction ports communicating with the inner cavity of the cavity defined on the inner wall of the protective cover, and a clamping mechanism provided within the protective cover;

[0006] The inner cavity of the containing box is fixedly connected to a fan, and the air inlet of the fan is connected to the inner cavity of the cavity through a connecting pipe. The bottom of the containing box is fixedly connected to a connecting joint, and the other end of the connecting joint is disassembled and connected to a filter tank through a flange. The interior of the filter tank is fixedly connected to the filter tank, and an exhaust window is provided on the other side of the filter tank. The air outlet of the fan is connected to the inner cavity of the connecting joint through a guide pipe.

[0007] Furthermore, it also includes a bottom plate, which is located below the storage box, and a plurality of first electric telescopic rods are vertically fixedly connected between the upper surface of the bottom plate and the bottom of the storage box.

[0008] Furthermore, an inspection cover is detachably connected to the surface of the storage box by a plurality of screws.

[0009] Furthermore, the clamping mechanism includes two motors, which are respectively fixedly connected to the front end face and the rear end face of the protective cover. The output shaft of the motor rotates and extends to the inner cavity of the protective cover, and is fixedly connected to a second electric telescopic rod. The inner end of the second electric telescopic rod is fixedly connected to a U-shaped seat, and a clamping claw structure is provided inside the U-shaped seat.

[0010] Furthermore, the clamping structure includes a bolt, a twist handle and a clamping plate. The bolt is vertically arranged on the top of the U-shaped seat. The top end of the bolt is fixedly connected to the twist handle. The bottom end of the bolt rotates and extends to the inner cavity of the U-shaped seat. The clamping plate is rotatably connected to the bottom end of the bolt.

[0011] Furthermore, the plurality of dust suction ports are evenly spaced and arranged along the inner wall surface of the protective cover.

[0012] Compared with the prior art, the present invention has the beneficial effect that after the axle is clamped and fixed by the clamping mechanism, the axle can be welded. During the welding process, after the fan works, the air flow inside the cavity is extracted through the connecting pipe, so that the cavity generates negative pressure. The harmful gas generated during welding is sucked in through the suction port and discharged into the inner cavity of the connecting joint through the guide pipe. The harmful substances and irritating odors in the gas are purified by the purification plate and then discharged through the exhaust window, so as to avoid the harmful gas from affecting the surrounding area of ​​the device and improve the physical protection of the surrounding staff. After the motor rotates, the axle can be driven to rotate, which is convenient for welding at different angles. After the second electric telescopic rod is extended and retracted, the distance between the two U-shaped seats can be adjusted, which is convenient for clamping and fixing axles of different specifications, which is beneficial for welding work.
