Abstract
Disclosed is an automatically rotary cutting end mill belonging to the mechanical process. The utility model is composed of a cutter body, a circular shear blade and automatically rotary devices. wherein the rotary devices are evenly distributed along the rim of the cutter body and are commonly of 3-18 pieces, and an installation hole is opened at the rim position of the cutter body; a transmission shaft of the automatically rotary device and a bearing are arranged in the installation hole, a circular tool apron is arranged at one end of the transmission shaft, a bolt is used for fixed the circular shear blade on the tool apron through a press block, the tool apron and the shear blade are rotated with the transmission shaft; and a dust helmet is arranged at the tail part of the automatically rotary device. The cutting shear blade of the utility model can automatically rotate in the end milling process for continuously changing the contact position of the workpiece, so that the process situation is improved, the wear is reduced, the service life of the tools are prolonged, and the process efficiency is increased.
Description
Affiliated technical field
The utility model belongs to field of machining, particularly a kind of self-rolling type cutting end milling cutter.
Background technology
Traditional face cutter is fixed on the cutter hub, and in milling process, cutter and the surface to be machined generation high temperature that rubs repeatedly quickens the wearing and tearing of cutter, must change cutter behind the processing certain hour, influences cutter life and working (machining) efficiency.
Summary of the invention
Can not rotate at existing face cutter, the problem that easy to wear in process, life-span is short, influence working (machining) efficiency, the utility model provide a kind of can rotation in process, reduce to wear and tear, prolong the self-rolling type cutting end milling cutter of cutter life.
The utility model is by cutter hub, form from tourelle, annular blade.Be equipped with 3-18 respectively from tourelle on cutter hub, evenly distribute from the periphery of tourelle at cutter hub, milling cutter is made up of power transmission shaft and bearing from tourelle, and bearing is rolling bearing or sliding bearing.Power transmission shaft is many steps axle, has the installing hole that is used for fixing from the step of tourelle at the peripheral position of cutter hub, and power transmission shaft is installed in the hole together with bearing, and afterbody is fixed on the inner ring sleeve of auxiliary bearing with nut.One end of power transmission shaft is equipped with annular tool rest, and tool rest is fixed on the power transmission shaft by nut, and screw is fixed on annular blade on the tool rest by compressing tablet, and tool rest rotates with power transmission shaft with blade.In the installing hole on cutter hub, the different sections of power transmission shaft are equipped with three cover bearings, radially rigid bearing is equipped with in the front portion, the axial restraint bearing is equipped with at the middle part, afterbody is equipped with auxiliary rigid bearing, radially between rigid bearing and the axial restraint bearing levelling packing ring is being housed, the stop washer that prevents that hold-down nut is loosening is being housed from the power transmission shaft two ends of tourelle.Front end at journal bearing is equipped with sealing ring, and sealing ring is housed in sealing ring, and sealing ring is fixed on the cutter hub by jump ring.At afterbody dust cover is housed from tourelle, dust cover is fixed on the cutter hub, and milling cutter diameter is Φ 100mm-Φ 800mm, and cutting plate for milling cutters is made with high-speed steel or Hardmetal materials, the cutting plate for milling cutters diameter is Φ 20mm-Φ 180mm, and edge of milling cutter radially drift angle Φ is 8 °-28 °.
Cutting tip of the present utility model is the rotation automatically along with the generation of Milling Force in the face milling process, cutting knife because from then constantly change and the workpiece contact site, thereby improved processing conditions, processing temperature can not improved, wearing and tearing can very fast increase, thereby has prolonged cutter life.Can improve process velocity like this, reduce and change the cutter number of times, improve working (machining) efficiency.
