The burr of housing endoporus, reaming knife of the prior art since size is fixed, are unsuitable for being mounted in small drilling machine, and knife
Tool wears non-exchange blade so that processing cost is higher.
Invention content
Shortcoming in for the above-mentioned prior art, the utility model are intended to provide a kind of gear jacket reaming device,
It is adapted to mount in small drilling machine and uses, and blade is replaceable, and cooperation special fixture uses high precision machining.
The utility model employs following technical scheme to achieve these goals：
A kind of gear jacket reaming device, including the fraising knife being set on drilling machine and the positioning being positioned on drilling machine base
Fixture, the fraising knife include tool apron, blade, it is characterised in that：The tool apron includes shank section and mounting portion, the mounting portion
With the locking slot and insert groove being arranged in parallel, the blade positioning is used in having in the insert groove, in the locking slot
Lock the threaded hole of the blade；The positioning fixture includes fixture mounting base and clamp body, and it is heavy to have at the top of the clamp body
Head bore, the counter sink upper edge annular equidistant placement have limiting slot there are three U-type groove in one side wall surface of the U-type groove.
Further, the locking slot and insert groove include three, and the annular arrangement along the periphery of mounting portion.
Further, the shank section is the column of three face chamfered edges.
Further, there is chip space on the rake face of the blade.
Further, the mounting base both ends are equipped with mounting groove.
Further, another side wall surface of one of them U-type groove is the gap of Milling Process.
The beneficial effects of the utility model include：Inner-hole burr is removed suitable for gear jacket, blade is adjusted and can
To replace, solves high cost caused by replacing cutter, machining accuracy higher is easy to operate.
