Rapid broaching device for angular milling head

Abstract

The invention discloses a rapid broaching device for an angular milling head. The rapid broaching device comprises a tool pull rod, a rotary flange, a clamping module, a pull nail, a cover plate and ablowing module. One end of the tool pull rod is coaxially and fixedly connected with a tool handle. The other end of the tool pull rod is coaxially and fixedly connected with one end of the pull nail. The other end of the pull nail is matched with the clamping module. The tool handle is in conical face fit with an output shaft of the angular milling head. The angular milling head can be fixed andtensioned through the tool pull rod and the pull nail. The output shaft of the angular milling head is coaxially and rotationally connected with a shell of the angular milling head. According to therapid broaching device for the angular milling head, through cooperation of a gas nozzle, a gas source, the blowing module, a ventilation channel and the clamping module, a tool is tensioned, and thereleasing time is smaller than 10 s, so that the tool is tensioned and released automatically and quickly, and the problems of the low efficiency and unstable clamping force brought by traditional manual broaching are avoided.

Description

technical field [0001] The invention relates to a quick broaching device for an angle milling head, which belongs to the field of numerical control processing technology and equipment, and is mainly used for fast tightening and dismounting of the angle milling head tool of a boring and milling machine. Background technique [0002] Aerospace shell segments are mostly cylindrical, conical, and special-shaped structures, and the internal shapes of shell segments include windows, explosive bolt boxes, bosses, brackets, grids, and ring grooves, which require the use of angle milling heads on boring and milling machines for internal molding. Milling. [0003] At present, the broaching tool of the angle milling head of the boring and milling machine adopts the method of manually tightening the bolt. The rotating part is fixedly connected. [0004] With the bolt broaching method, the efficiency of installing and dismounting the tool by the angle milling head is low, resulting in ...

AI Technical Summary

Problems solved by technology

[0004] Using the bolt broaching method, the efficiency of installing and dismounting the tool by the angle milling head is low, resulting in a long waiting time for equipment shutdown and a low level of automation in the broaching process

The tightening effect of the bolt broach depends on the experience of the operator, and the consistency of the tensioning force is poor

Too little tension will lead to product processing quality problems due to tool looseness during the cutting process; too much tension will cause difficulty in tool disassembly, wear or damage to the thread at the back end of the tool holder, and shorten the service life of the tool holder
