Description

Technical Field

[0001] The utility model belongs to the technical field of protection devices, in particular to a bridge housing shell metal processing protection device. Background Art

[0002] The transmission axle housing is an important part of the vehicle, and the metal processing parts of it not only play a role in installation and positioning, but also are related to the transmission ratio of the vehicle. However, due to the special shape of the axle housing, it is impossible to arrange the important metal processing process at the end. It is necessary to carry out the metal processing process first, then grind the axle housing shell, and then weld it; but because the axle housing shell is a cast part, some positions are difficult to meet the requirements of welding processing by grinding alone, and a large amount of grinding can easily lead to a decrease in the quality of the axle housing. Therefore, a protective device is needed to completely wrap the metal processing parts of the axle housing, so that after the metal processing process is completed, it will be sent for shot blasting, and the axle housing can be more effectively polished to the standard required for welding processing.
