Abstract

The invention relates to a broaching tool for a blade tenon. The broaching tool comprises a workbench, a tool clamp and an auxiliary supporting device; the tool clamp is arranged on the workbench and comprises a fixed seat, a profiling clamp and a rotary seat with a central axis, and the rotary seat is arranged on the fixed seat in the mode that the rotary seat can rotate around the central axis of the rotary seat; the auxiliary supporting device comprises a first supporting block and a second supporting block, the first supporting block and the second supporting block are both movably arranged on the rotary seat and can be close to or away from the blade tenon, and therefore the auxiliary supporting device at least has a first state and a second state, in the first state, the first supporting block moves towards the blade tenon and abuts against the end face of the blade tenon, and the second supporting block is far away from the side face area of the blade tenon; and in the second state, the second supporting block moves towards the blade tenon and abuts against the side face of the blade tenon, and the second supporting block is far away from the end face area of the blade tenon. According to the broaching tool, the blade can be firmly clamped, the blade tenon machining procedure is simplified, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of blade tenon processing, in particular to a tool for broaching blade tenon. Background technique [0002] Turbine blades are important components of aero-engines. The blades of the worm gear and the worm gear disc are usually connected by the tenon of the blade and the tenon and groove on the outer periphery of the worm gear disc. The machining accuracy of the tenon of the blade directly affects the performance of the product. Such as figure 1 As shown, the processing of the blade tenon 12 generally includes the processing of the front and rear tenon side sections 13, the left and right sides of the tenon end surface section 14 and the bottom groove 15 of the tenon. Correspondingly, the blade tenon has two opposite sides 16, two Two opposite end surfaces 17 and a bottom surface 18 on the side away from the blade body 11. At present, five-axis CNC machining centers are generally used for blade tenon mach...
