AI Technical Summary
Existing steel pipe reaming equipment has shortcomings in adjusting the reaming depth and positioning the steel pipe, making it difficult to meet the needs of convenient operation.
A steel pipe reaming machine was designed, which includes a reaming device, a positioning device, and a clamping device. The reaming device adjusts the reaming depth by means of a stroke nut, the positioning device positions the steel pipe by means of a positioning plate and a support shaft, and the clamping device fixes the steel pipe by means of a clamp.
It enables easy adjustment of the hole enlargement depth and stable positioning of the steel pipe, is simple to operate, and avoids damage to the steel pipe.
