Abstract

The invention discloses a rotary shaft type drilling tool which comprises a clamp body, a rotary shaft, an opening washer and a compression nut. The rotary shaft is rotationally arranged on the clamp body, and the opening washer and the compression nut are matched with the rotary shaft to be used for pressing a workpiece to be processed. The rotary shaft type drilling tool has the advantages that the rotary shaft type drilling tool is compact and simple in structure, facilitates loading and unloading of the workpiece, facilitates turning and drilling and does not need tool setting each time.

Description

technical field [0001] The invention relates to a process equipment for mechanical processing, which is aimed at the drilling tooling equipment for the air distribution parts of the rock drill, specifically for the valve cabinet on the valve cabinet tube wall of one of the main air distribution parts of the pneumatic rock drill. And the drilling tooling of the radial air holes arranged crosswise. Background technique [0002] Rock drilling equipment is used to break soft ore, demolish solid or cement buildings, mine clay, etc., and the rock drilling equipment is mainly pneumatic rock drills. The valve cabinet involved in this design is one of the main gas distribution parts of the pneumatic rock drill. The part requires high precision and many processing procedures. Among them, there are two coplanar and cross-arranged radial air holes on the wall of the valve cabinet. The angle between the two holes is 144 degrees. The two cross radial air holes are carried out on the dri...
