Description

Technical Field

[0001] This utility model belongs to the technical field of drilling devices, and in particular relates to a drilling device for processing the lower guard plate of automobile B-pillar. Background Technology

[0002] A B-pillar underbody protector is a protective device installed at the bottom of the B-pillar on the side of a vehicle. It protects the structure below the B-pillar and prevents damage from impacts to the vehicle body. It is typically made of plastic or other durable materials and offers scratch and abrasion protection. The design and shape of the B-pillar underbody protector vary depending on the vehicle model, and the drilling locations will also differ accordingly.

[0003] Since the shape of the B-pillar underbody protection plate varies depending on the vehicle model, and some B-pillar underbody protection plates are made according to the size of the vehicle's interior space, and there are height differences in different parts of the B-pillar underbody protection plate, the existing auxiliary positioning devices cannot accurately adjust the protection plate to adapt to different shapes of protection plates. Therefore, a drilling device for processing automotive B-pillar underbody protection plates is proposed. Summary of the Invention
