Machining tool for die forging rotor blade

Abstract

The invention discloses a machining tool for a die forging rotor blade. The machining tool comprises a base and a fixing device arranged on the upper surface of the base. The fixing device comprises apressing plate, a positioning pin, a positioning block, an adjusting screw and a baffle. The pressing plate is connected with the positioning block. The positioning block is connected with the baffle. The positioning pin is arranged on the positioning block. The adjusting screw and the pressing plate are in threaded connection. The machining tool further comprises a positioning tensioning sheet arranged on the lower surface of the base and a chip hole formed in the side edge of the base. The machining tool adopts integral structure design and is simple in structure and convenient to operate;and meanwhile, the machining rigidity of the tool is improved, and the qualified rate of parts is further increased. The base and machine tools are connected through the positioning tensioning sheet,interchangeability between the machine tools is high, the machining tool can be used on the machine tools of different brands, the positioning accuracy of a clamp and the interchangeability of the tool are improved, and management is facilitated. A chip capable of being encoded is mounted the base through the chip hole, thus automatic integration engineering is achieved advantageously, part data flow management is achieved, the serial number of each part is accurately tracked, and the machining efficiency of the parts is improved.

Description

technical field [0001] The invention belongs to the technical field of aero-engine parts processing, and relates to a die-forged rotor blade processing tool. Background technique [0002] The positioning method used in the traditional tooling design is: the tenon double-sided positioning, the bottom surface positioning and clamping method. This method fully considers the working state of the part and the tolerance of the part, and is essentially a complete positioning method based on the high precision of the tenon processing of the part. Its advantages are stable and reliable part positioning and fit parts working state. However, this method has the following shortcomings: because the domestic tooling design and manufacturing accuracy and material heat treatment level cannot achieve precise positioning, long-term use directly affects the blade machining accuracy, resulting in out of tolerance parts. SUMMARY OF THE INVENTION [0003] The purpose of the present invention ...
