Description

Technical Field

[0001] The utility model relates to the field of wheel hub processing, in particular to a rapid heat dissipation device for wheel hub welding. Background Art

[0002] The wheel hub refers to the part of the vehicle where the wheel is mounted, usually made of metal. It is the central part of the wheel and is used to connect the wheel tire and the vehicle's suspension system. The main function of the wheel hub is to support the weight of the vehicle and provide contact with the ground so that the vehicle can run smoothly. With the advancement of technology, modern wheels usually use lightweight materials such as aluminum alloy to reduce the overall weight of the vehicle and improve fuel economy. In addition, some high-end vehicles also use aerodynamically designed wheels to reduce air resistance and improve vehicle performance.

[0003] The wheel hub is mainly composed of a rim and spokes, and the rim and spokes are usually connected by welding, that is, a pair of spokes are welded to the two ends of the rim. At the same time, the wheel hub is generally formed by injection molding and rolling. Similarly, rolling forming also requires the hub forming plate to be bent and then welded. Therefore, welding is one of the indispensable processing steps in wheel hub manufacturing. Nowadays, companies have invested in robots or manipulators to replace manual welding to improve welding accuracy. However, while the accuracy and efficiency of robot welding are improved, the heat increases faster during wheel hub welding. Nowadays, most wheel hubs are made of aluminum alloy. In continuous and rapid welding, the heat accumulates greatly, which may cause the wheel hub to deform, affecting the subsequent spinning forming process, resulting in the geometric shape of the wheel hub not meeting the requirements. Summary of the invention

During the welding process, the clamping plate 8 can be adjusted by the rotating base 7 to rotate and adjust the welding position to match the on-site welding conditions.

[0031] A driving gear is provided at one end of the main motor 9 shaft near the rotating seat 7 . The motor 9 shaft passes through the fixed base 6 and extends to the inside of the rotating seat 7 , and the driving gear is meshed with the driven gear.

[0032] See also Figure 5 The clamping plate 8 is provided with a clamping block 8a, and a cylinder is provided inside the clamping plate 8. The telescopic rod of the cylinder is fixedly connected to the clamping block 8a. The clamping plate 8 has two clamping modes, which can be selected according to the production of the enterprise.

The clamping block 8a contacts the inner wall of the wheel hub 14 to tighten and form a clamp; the other is: it can be used when the placement ring inside the wheel hub 14 already has a hole, and the wheel hub 14 is bolted to the bolt fixing hole 8b by fixing bolts. After clamping the wheel hub 14 in two ways, welding work can be carried out.

When the fan blades 12 are working, air is introduced from the air inlet 10a and blown toward the welding position. During the blowing process, the airflow is guided and concentrated by the guide channel 11, and dust in the air is filtered out by the filter plate 11a during the process, so that the heat dissipation process is clean and dust is prevented from falling into the welding position and affecting the welding quality when the room is relatively dirty.

[0036] The guide channel 11 is fixedly connected to the bottom of the protective cover 10. A filter screen 11a is provided at one end of the guide channel 11 close to the protective cover 10.

[0037] The specific working principle is: when in use, the wheel hub 14 is placed on the clamping plate 8, and the clamping and fixing method is selected according to the type of the wheel hub 14. If the wheel hub 14 is formed by a rolled plate and the internal placement ring (thorn) has not been punched, it is clamped by the cylinder inside the clamping plate 8. If there is a placement ring, it is connected by bolts. After connection, the wheel hub 14 is fixed, and the welding gun 4 is driven by the manipulator 3 for welding. During the welding process, the fan blades 12 provide wind power to dissipate the heat of the wheel hub 14.
