Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing equipment, in particular to a wheel hub drilling auxiliary tool. Background Art

[0002] Wheel hub drilling is a complex and professional process that involves precise calculation, positioning and subsequent processing. To ensure safety and effectiveness, before drilling, it is necessary to comprehensively consider the material, structure and use environment of the wheel hub, accurately calculate the diameter, number and depth of the required holes, and accurately locate the drilling position on the correction surface.

[0003] When drilling a hole in the wheel hub, the drilling position is mostly located by the axial distance, and the wheel hub needs to be fixed and limited during drilling to avoid the hole position offset caused by shaking of the wheel hub during drilling operation, which affects the assembly effect after drilling. However, it is not convenient to adjust the position of the wheel hub during drilling processing, and the fixing method is relatively arbitrary, which can easily cause wear on the wheel hub surface, thereby affecting the appearance of the wheel hub. In order to solve the above problems, while facilitating the fixing and limiting of the wheel hub, it is convenient to adjust the wheel hub according to the drilling requirements of different positions, thereby avoiding problems such as hole position offset and wear during drilling. For this reason, we propose a wheel hub drilling auxiliary tooling. Utility Model Content
