Abstract
The invention discloses an adjustable end milling cutter and an adjustable assembly structure applying the same. A cutter body of the end milling cutter comprises a front end threaded part, a middle part and a rear end threaded part; a waist-shaped key groove is formed on the outer surface of the cutter body; a front end adjusting nut and a rear end adjusting nut are in threaded connection with the front end threaded part and the rear end threaded part respectively; a part of the waist-shaped key groove is exposed between the front end adjusting nut and the rear end adjusting nut; in the end milling cutter adjustable assembly structure, a conical seat is connected with a milling machine main transmission shaft; the number of cutter assembly holes in a carrying disk is unlimited; a directional groove is formed on the peripheral face of the carrying disk; and a directional jackscrew passes through a positioning hole in the directional groove so as to be pressed against the waist-shaped key groove of the end milling cutter. Compared with the prior art, the adjustable assembly structure has the advantages that: a relative position of the end milling cutter on the carrying disk in the vertical direction can be changed, so different end milling cutters can be assembled selectively; when the carrying disk rotates a workpiece, the end milling cutter cannot be rotated around the middle axial line of the carrying disk; a plurality of end milling cutters of which differences of height values are gradually reduced are arranged in a clockwise direction of the carrying disk sequentially; therefore, when the adjustable end milling cutter is used for machining, the surface of the workpiece is more smooth.
Description
Technical field
The present invention relates to a kind of end mill(ing) cutter, relate in particular to a kind of adjustable end mill(ing) cutter; The invention still further relates to a kind of adjustable package assembly of this end mill(ing) cutter of application.
Background technology
Milling cutter is mounted in (vertical knee-type milling machine, horizontal milling machine, production miller, plain-milling machine, universal milling machine etc.) on the milling machine; Be used for the dedicated tool of processing parts (mainly being the metal material part); Make blade act on surface of the work through the cutter rotation and form specific shape and required precision; Wherein end mill(ing) cutter is the cutter that is specifically designed to processing plane, and the accuracy of product, fineness, the range of work and operating efficiency then depend on quality and the height of operating personnel's technical merit of the technical performance of milling machine, cutter and auxiliary equipment.
The kind and the purposes of milling cutter are a lot, and great majority adopt high-speed steel, tool steel material manufacturing.A kind of as wherein of end mill(ing) cutter, high temperature resistant and the impact resistance of its blade is relatively poor, can not be too fast so add the man-hour linear velocity, so as not under high pressure and function of friction generation high temperature and damage blade, this working (machining) efficiency of pavilion is lower.Though ordinary rigid alloy end mill(ing) cutter has solved the problems referred to above, but still have following technological deficiency: existing end mill(ing) cutter needs the special-purpose mechanical secondary process of whetting a knife; Existing cutter inefficiency; Existing milling cutter can not be given full play to lathe usefulness; The existing cutter depth of cut, working width are random poor; Existing cutter head performance is to the character and the processing request specific aim poor selectivity of rapidoprint.This shows that the end mill(ing) cutter of prior art can not satisfy people's demand.
