Abstract
The utility model provides an assembled type bulb milling tool, and relates to a bulb milling tool, aiming to solve the problems that as the existing bulb milling tool for milling the curve surface of a molded line of a turbine blade is integrated, the replacement cost of the tool is high due to the fact that the tool is entirely declared when the tool is worn, an edge is broken or the tool cannot be milled. The assembled type bulb milling tool provided by the utility model comprises a tool head and a tool body; the tool body sequentially comprises a tool head mounting section, a transition section and a conical handle from front to back; a back thread hole is formed at an axis of the back end face of the tool body; the rear angle of the tool head is 15-20 degrees; a front thread hole is formed at the axis of the front end face of the tool body; an outer thread matched with the front thread hole is formed at the tail part of the tool head; and the outer thread at the tail part of the tool head is in threaded connection with the front thread hole of the tool body. The assembled type bulb milling tool provided by the utility model is used for milling the curve surface of the molded line of the turbine blade.
Description
Technical field
The utility model relates to a kind of rose cutter.
Background technology
Carbide alloy bulb milling cutter is the dedicated tool of milling turbine blade molded lines curved surface; The cutter hub of existing carbide alloy bulb milling cutter and cutter head are for being made into integration; When tool wear, tipping or again during reconditioning just integral body scrap, the expense that causes being used on the cutter changing is bigger.
The utility model content
The purpose of the utility model is to be one in order to solve the existing rose cutter that is used for milling turbine blade molded lines curved surface; When tool wear, tipping or again during reconditioning cutter integral body scrap; Cause the big problem of cutter changing expense, and a kind of assembled rose cutter is provided.
The utility model comprises cutter head and cutter hub; Cutter hub is followed successively by cutter head construction section, changeover portion and taper shank from front to back; The rear end face axis place of cutter hub is provided with the rear thread hole, and the relief angle of cutter head is 15 °～20 °, and the front end face axis place of cutter hub is provided with the preceding thread hole; The afterbody of cutter head is provided with the external screw thread that matches with the preceding thread hole, and the external screw thread of cutter head afterbody is threaded with the preceding thread hole of cutter hub.
The utility model compared with prior art has following effect: be threaded because cutter head and cutter hub adopt; Make that the rose cutter of the utility model is the assembled rose cutter; When tool wear, tipping or again during reconditioning, can directly change cutter head, reduced the expense of changing cutter.
