Abstract

A vertical milling head capable of keyway-milling for milled spindle of a lathe comprises a triangle seat equipped on the rear of the lathe body, ladder shaped grooves on both sides on the frond side, a bracket fixed on the upper end, a lead screw with its one end getting through a bracket hole and being fixed to two dorsal screw cap to enable the lead screw to rotate but not move upwards and downwards and the other end entering into the die head and matching a nut, an end socket handle, a die head with its both back sides being clamped in the ladder shaped grooves of both sides in its front face, and a rotary handle capable of driving the die head moving upwards and downwards. A top wire is provided to right side of the lathe body, capable of locking the die head. Bearing sleeves at both ends of a front hole of the die head are provided to fix bearings on both ends of a principal axis in which a milling cutter is fixed by a tightening bolt. A motor is mounted on the front cover of the die head, which gear wheels enters the front cover of the die head to joggle reduction gears for a reduction drive, wherein the bevel gears on front end of the reduction gears enters into the die head and joggle rbevel gears of the principal axis for a reduction drive. The vertical milling head is fixed to a knife bed of a lathe, and the rotary handle drives the die head moving upwards and downwards, then a three-dimensional moving cutting pin is formed by milling cutters with a landscape orientation and longitudinal moving cooperation of a big slide carriage and a small slide carriage on a lathe.

Description

End mill head

Affiliated technical field

The utility model relates to a kind of machining topping machanism, especially can make the end mill head of machined into keyway.

Background technology

At present, known lathe can be processed various axles, but can not process the keyway on the axle, and the handy milling machine processing of keyway has not only increased processing cost, and secondary is installed to proofread and correct also to reach and is trouble.

Summary of the invention

Can not process the deficiency of keyway in order to overcome traditional lathe, the utility model provides a kind of end mill head for lathe, and this end mill head can make directly keyseat of the intact axle of lathe car, both need not be for keyseat had been equipped with milling machine, and the trouble of also having avoided secondary to be installed and to proofread and correct.

The technical scheme that its technical problem that solves the utility model adopts is: lower end, body back side triangle is sat, both sides, body front ladder-type trough, upper end two bolting carriages, leading screw one end passes bracket hole and two back ofs the body and emits to cooperate and fix, leading screw can be rotated can not move up and down, the termination handle, leading screw other end Shen is gone in the head metapore and is cooperated with nut, head back dual-side is gone in the ladder-type trough of both sides, body front along the Shen, two pressing plates are fixed on the ladder-type trough of both sides, body front by screw respectively, make head back dual-side along being clipped in the ladder-type trough of both sides, body front, head is moved up and down under the driving of leading screw.A jackscrew is established on the body right side, the lockable head.The preceding hole of head two end axles bearing sleeve fixed main shaft bearings at both ends, the main shaft middle-end is bevel gear fixedly, and in the main shaft, bolt hangs tight milling cutter and fixes.Bearing, the reduction gearing order tight fit reduction gearing axle middle-end of packing into, in the bearing tight fit loading unit front aperture, reduction gearing axle one end bevel gear Shen is gone in the head and main shaft bevel gearing deceleration transmission, and other end Shen is gone in the front capping tile cover, protecgulum is buckled in the head front, is fixed by screw.Motor is fixed on the protecgulum front by screw, and the motor gear Shen is gone in the protecgulum and reduction gearing interlock deceleration transmission.Behind the intact axle of machined into, lower end, end mill head body back side triangle is sat, insert in the cutter groove on the lathe cutter platform, tighten jackscrew, fixing end mill head, rotary handle can drive head and move up and down, and the transverse and longitudinal motion by lathe big cargo chute, little slide carriage cooperates again, make milling cutter constitute three-dimensional motion and cut pin, reach the purpose of machined into shaft key groove.

The beneficial effects of the utility model are, can make the intact axle of machined into after, directly process keyway, both removed equipment from for processing keyway adapted, also avoided secondary to be installed and imitated positive trouble, the most of part of end mill head adopts the common standard part, and is simple in structure.
