Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a position-limiting drilling machine capable of freely adjusting a drilling position. Background Art

[0002] After the processing and shaping of the pipe is completed, holes need to be punched on its surface to facilitate the subsequent docking between the pipes. Some pipes with special installation forms need to be punched at different angles of the pipe.

However, this has high requirements on the drilling machine and the fixture. The method of positioning by using the hole positions through multiple clamping can achieve the positioning effect, but there is a certain deviation in the relative angles between the hole positions, and the matching accuracy between the pipes during subsequent installation cannot be guaranteed.
