Constant punching device

Abstract

The invention relates to a constant punching device, and belongs to the technical field of pipe or bar punching and machining. According to the technical scheme, the constant punching device comprises a constant puncher and a positioning bolt (7); the constant puncher is a polygonal prism body (5); a workpiece manhole (1) is arranged on the end face of the polygonal prism body; a plurality of working holes (3) are arranged on the lateral face of the polygonal prism body; a positioning screw (2) is further arranged on the lateral face of the polygonal prism body; the positioning screw is matched with the positioning bolt; and the working holes, the positioning screw and the workpiece manhole are communicated. The constant punching device provided by the invention has the beneficial effects in that after the pipe or the bar which has the constant internal diameter and the constant external diameter and needs to be punched is fixedly arranged on the constant punching device, the pipe or the bar is directly punched without measuring the size in use; and furthermore, no sliding excursion is generated, so that a punching position is accurate; the convenience in use can be realized; the labor intensity is reduced; the effect of the labor efficiency is improved; the constant punching device is applicable to generally punching in scale; the punching precision can be improved; the position measurement cannot be carried out; and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a constant punching device for punching fixed-type pipes or rods, belonging to the technical field of pipe or rod punching processing. Background technique [0002] At present, in the process of daily production and machine maintenance, it is often necessary to drill holes in the same workpiece at a constant position. Position measurement is required for each drilling process to determine the drilling position, and errors will inevitably occur in each measurement. In this way, the accuracy of the punching position cannot be guaranteed, and at the same time, repeated measurement wastes time and also causes a waste of human resources. Contents of the invention [0003] The object of the present invention is to provide a constant punching device, which does not need to measure the size, does not cause sliding offset, accurate punching position, easy to use, reduces labor intensity, improves labor efficiency, and solves the above...
