Description

Work fixture for boring workpiece

Technical Field

The utility model relates to a relevant technical field of anchor clamps specifically is a frock clamp of work piece bore hole.

Background

As is well known, boring is a processing mode often encountered in a machining process, a common boring device is a vertical drilling machine, and when a hole is processed, a workpiece needs to be positioned by a clamp, and then boring is performed. However, with the diversification of workpieces, the existing boring clamp cannot meet the processing requirement. When the protruding position processes the transverse hole on ring shape work piece surface, because the work piece is ring shape and the hole that needs to process is the transverse hole, to upright drill, it is difficult to process, the method of general adoption is that vertically place the ring shape work piece and step up through anchor clamps, after being vertical hole with the transverse hole rotation, carry out the bore hole processing again, but this kind of anchor clamps when processing a plurality of transverse holes, often need take off the rotation of work piece and fix the processing again, it wastes time and energy to process, influence machining efficiency, and be difficult to guarantee the precision of bore hole.
