AI Technical Summary

Technical Problem

Existing hole expanders lack adjustability and are difficult to adapt to expanding materials with large widths.

Method used

A hole expander comprising a support frame, an adjustment device, a drive unit, a drill barrel, a slide bar, a threaded rod, a turntable, a main brush, and a secondary brush is designed. The combination of these components realizes a hole expander for the support frame, and the hole expander with these components achieves the adjustability of the support frame. By setting a combination of a placement frame, a slide bar, a threaded rod, and a moving block, the position of the support frame can be adjusted to accommodate materials of different specifications.

Benefits of technology

The adjustable capability of the hole expander is realized, which can adapt to materials of different specifications, reduce the random movement of materials during the hole expansion process, and improve the flexibility and efficiency of hole expansion operation.
