CN201329440Y - Long slot miller - Google Patents

Abstract

The utility model discloses a long slot miller; chip dividing grooves (1) are crossed and distributed on the tool end edge thereof; an arc tool edge (2) is arranged at the tool tip; the processed getter part at the slot bottom adopts smooth arc transition; and the notch chamfer angle alpha on the tool side is 45 degrees. The utility model has benefits as follows: as a whole disc-milling cutter, the dedicated long slot miller solves the getter problem of the slot bottom and the chamfer angle problem of the notch simultaneously in one processing; the processed slot has a standard and regular shape; and the processing period is shorted, manpower and material resources are saved, and the time cost is reduced. Therefore, the long slot miller has high efficiency and high quality.

Description

The long keyway milling cutter

Technical field

The utility model relates to a kind of the combined type dish milling cutter, particularly long keyway milling cutter in the keyway process tool.

Background technology

Processing general major key slotting cutter of keyway or face and side cutter, metal saw are finished.Chamfering is wanted in the key piece bottom that so just requires to cooperate with it, and perhaps keyway bottom land both sides are left the groove of cooling down and guaranteed compact conformation.For the notch that makes things convenient for that assembles is also wanted chamfering.Keyway notch chamfering or manually finish or reorientate clamping machine on lathe all must secondary operations just can be finished.

Summary of the invention

The purpose of this utility model promptly is to overcome the shortcoming of prior art, be provided at the long keyway milling cutter of the chamfering problem of the problem of cooling down that solves the keyway bottom land in the time processing simultaneously and notch, it is the integral disc milling cutter that is specifically designed to the processing keyway, the keyway shape standard that processes is neat, and shortened the process-cycle, save the man power and material, reduce time cost.

The purpose of this utility model is achieved through the following technical solutions: the long keyway milling cutter, be staggeredly distributed with chip dividing groove on the knife end sword, the cutter point of a knife is the circular arc blade, and it is smooth arc transition that the keyway bottom that it processes is cooled down partly, and the notch chamfering α of cutter side is 45 °.

By top narration as can be seen, the utlity model has following advantage: the long keyway milling cutter is the integral disc milling cutter that is specifically designed to the processing keyway, this dedicated tool solves the problem of cooling down of keyway bottom land and the chamfering problem of notch simultaneously in time processing, the keyway shape standard that processes is neat, and shortened the process-cycle, save the man power and material, reduce time cost.Therefore the long keyway milling cutter is high efficiency and high-quality milling cutter.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1 and Figure 2, the long keyway milling cutter, be staggeredly distributed with chip dividing groove 1 on the knife end sword, the chip dividing groove that is interspersed makes in the processing tiny being easy to of iron filings get rid of, thereby to the keyway cell wall can not form the extruding and the friction, improved the roughness and the dimensional accuracy of surface of the work, effect is particularly outstanding when processing darker keyway.The cutter point of a knife is a circular arc blade 2, it is smooth arc transition that the keyway bottom that it processes is cooled down partly, it is smooth arc transition that the keyway bottom that the circular arc blade of this cutter point of a knife processes on this knife end sword is cooled down partly, and its effect is better than the thin metal saw fluting of traditional usefulness.When driving member is when adopting flat key to come carry-over moment, because being the circular arc smooth transition, the keyway bottom avoided stress to concentrate the crackle that produces, improved the service life that load is transmitted workpiece.The notch chamfering α of cutter side is 45 °, makes assembling more convenient.

Claims (1)

1, long keyway milling cutter is characterized in that: be staggeredly distributed with chip dividing groove (1) on the knife end sword, the cutter point of a knife is circular arc blade (2), and the notch chamfering α of cutter side is 45 °.
