Technical Field
The utility model relates to a cutter technical field, concretely relates to a milling cutter for processing worm.
Background
The thread form angle of the worm is a stainless steel material which is difficult to machine. The original common lathe is used for machining the special sawtooth-shaped threads, and because the outer diameter of a part is small, the resistance is large when the threads are turned, the part is easy to turn and deform or even turn off, the cost is high, and the efficiency is low. Moreover, machining in a common machine tool needs to be performed back and forth between different processes and different types of work. Frequent turnover and waiting among the working procedures waste a lot of time, and the processing period of the parts is prolonged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the not enough among the prior art, and provide a milling cutter for processing worm with low costs, efficient.
The purpose of the utility model is realized through the following technical scheme:
the milling cutter for machining the worm comprises a cutter body and a cutter bar, wherein two groups of cutting edge assemblies which are used for machining a worm tooth-shaped groove and are parallel up and down are arranged on the cutter body, each group of cutting edge assembly is provided with three cutting edges which are uniformly distributed on the periphery of the cutter body, a through hole is formed in the center of the cutter body, and the cutter bar is inserted into the through hole and is fixedly connected with the cutter body.
Wherein the front angle of the cutting edge is 6 degrees, and the rear angle is 8 degrees.
The cutting edge comprises a first cutting edge, a second cutting edge and a third cutting edge which are sequentially connected, the included angle between the first cutting edge and the third cutting edge is 20-40 degrees, during machining, the first cutting edge and the third cutting edge are respectively abutted against the side wall of the tooth-shaped groove of the worm, and the second cutting edge is abutted against the bottom wall of the tooth-shaped groove of the worm.
And the joint of the first cutting edge and the second cutting edge and the joint of the second cutting edge and the third cutting edge are in arc transition connection.
Wherein the height of the tool body is between 3cm and 5 cm.
The utility model has the advantages that: be provided with two sets of cutting edge subassemblies, make the profile of tooth groove that can two worms of one shot forming in same process, machining efficiency is high, simultaneous processing saves time, and adopt milling cutter processing in this embodiment, the centralization and the machining precision characteristics such as high of process have, production efficiency has also obtained very big improvement, production workman's intensity of labour has been alleviateed, labor conditions has been improved, it is big to have also effectively solved simultaneously that traditional structure adopts lathe tool turning screw resistance when, the problem of turning the part car warp or even the car absolutely easily, the life-span and the machining efficiency of cutter have been improved, production cost is reduced.
