Abstract

The invention relates to the technical field of machining, in particular to a high-precision punching device for axis hole machining. The high-precision punching device comprises a rotating mechanism,a synchronous sliding mechanism, a tray, clamping blocks and a punching mechanism, wherein the rotating mechanism is mounted on a rack; the synchronous sliding mechanism is mounted on the rotating mechanism; the tray is installed at the upper end of the synchronous sliding mechanism and located below the clamping blocks; the distances between the three clamping blocks and the axis of the synchronous sliding mechanism are the same, 120-degree included angles are formed between the clamping blocks, and the working ends face the axis of the synchronous sliding mechanism, and the clamping blockscan get close to or away from the axis of the synchronous sliding mechanism to be mounted on the synchronous sliding mechanism; and the punching mechanism is erected above the synchronous sliding mechanism, and the axis of the working end and the axis of the synchronous sliding mechanism are collinear; The high-precision punching device is high in punching precision, accurate in positioning and stable in structure.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a high-precision punching device used for machining a shaft center hole. Background technique [0002] Machining refers to the process of changing the external dimensions or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. Mechanical parts are composed of several surfaces. A datum must be determined for the relative relationship. According to the different functions of the datum, the datum can be divided into two categories: design datum and process datum. The datum used for workpiece positioning during processing is called the positioning datum. Only the unprocessed blank surface can be selected in the process. This positioning surface is called the rough datum, and the machined surface can be used as the positioning datum in each subsequent process. Thi...
