[0002] The automatic engraving device for the phase angle shaft of the steering column is a supporting device for the engraving process of the phase angle shaft of the steering column. The product belongs to the automobile steering system component and is a mechanical fixing device connected to the automobile steering wheel. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the automatic engraving device for the phase angle shaft of the steering column.

[0003] The existing steering column phase angle axis marking has certain drawbacks when used. Since the installation points of various parts of the automobile assembly are fixed and confirmed, the phase angle consistency of the left yoke and the right steering wheel installation parts must be ensured, otherwise the steering wheel will not be in the center position when installed. The traditional method is to use a paint pen to draw a line on the upper end face of the input shaft after assembling the left intermediate shaft assembly and the right steering column body to facilitate auxiliary positioning of the steering wheel installation. However, this process is easy to cause angle deviation by visual confirmation, and the paint pen marking is easy to fall off. Previously, the lines were drawn manually by visual inspection, with poor accuracy, and the paint pen was easily erased, which brought certain adverse effects to the actual use process. For this reason, we proposed an automatic marking device for the phase angle axis of the steering column. Utility Model Content
