Tooling mold for drilling columnar workpiece with external threads

Abstract

The invention relates to a tooling mold for drilling a columnar workpiece with external threads. The tooling mold is characterized in that it includes a drilling mold, and the drilling mold has a round through hole. The through hole is composed of a first round hole and a second round hole in concentric connection, the diameter of the second round hole is larger than or equal to the diameter of the first round hole, and the inner wall of the drilling mold corresponding to the second round hole is provided with internal threads. The sidewall of the drilling mold corresponding to the second round hole has a drilling mold hole, and the axial line of the drilling mold hole is perpendicularly intersected with the axial line of the second round hole. With the inventive mold, no line drawing operation is required, and machining precision and efficiency are high, without affecting workpiece surface smoothness and screw threads.

Description

technical field [0001] The invention relates to a tooling mold, in particular to an auxiliary tooling mold used for drilling cylindrical workpieces with external threads. Background technique [0002] At present, in the field of mechanical processing, when using a drilling machine to process radial holes on a cylindrical workpiece with external threads, it is necessary to draw a line on the cylindrical workpiece with external threads to be processed in advance, and then drill the position hole before drilling. Hole operation, and the workpiece to be processed must be fixed on the fixture of the drilling machine when drilling. The disadvantage of this processing method is that the processing accuracy is not high due to manual line drawing, and in mass production, the line drawing operation must be repeated, and the efficiency is low; in addition, because the workpiece is directly fixed on the drilling machine during processing On the fixture, the surface of the finished work...
