Description

Numerical control conical gear high speed mill teeth machine

Technical field

The utility model relates to a kind of system tooth processing of large-scale conical gear, particularly processes the high speed mill teeth machine of conical gear with the numerical control bed.

Background technology

Traditional conical gear processing is to adopt shaping machine or umbrella tooth to dig, and cutter all adopts high-speed tool steel; Cutting speed must under the condition of fully cooling, carry out during cutting, and cutting speed can not be above 40 meter/minute generally at 10～30 meters/minute; Operation is many, and the cutting time is long manually to be main, and power consumption is big; Production efficiency is low, is that the crudy of large-scale conical gear is difficult to satisfy specification requirement to workpiece.

The utility model content

The utility model purpose is the deficiency that exists to above-mentioned processing conical gear equipment; A kind of numerical control conical gear high speed mill teeth machine that is used for large-scale conical gear processing is provided; Use this equipment can shorten process-cycle of conical gear greatly, cut down the consumption of energy and can satisfy the specification requirement of conical gear.

For realizing that the technical scheme that above-mentioned purpose the utility model proposes is: a kind of numerical control conical gear high speed mill teeth machine; Comprise motor, in length and breadth to lathe bed, rotary table, in length and breadth to slide unit and guide rail, transmission shifting mechanism and digital control system; The cross slide that is positioned at vertical lathe bed bottom matches with the cross rail on horizontal lathe bed plane; Vertically the vertical guide rail of lathe bed side matches with the vertical sliding table that is fixed on the gearbox sidepiece; Milling cutter is housed on the output shaft of gear-box, it is characterized in that: the lower tile mounting base of rotary table parallels with horizontal lathe bed and is fixed on the lathe base, and lower tile mounting base and tile mounting base are connected to integral body; Rotary table and lower tile mounting base constitute the inclination angle; Upper and lower watt of seat is connected on the chassis through the adjustment axle, and the worm gear that is meshed with worm screw is connected through bearing output shaft and chassis, and the chuck that is used to clamp workpiece is fixed on the worm gear end face.

Described tile mounting base is connected with the bolt of lower tile mounting base through adjustment axle both sides, and the joint close of upper and lower watt of seat is positioned on the diameter line of adjustment axle.

The maximum gauge of the utility model processing conical gear can reach 4 meters, and Machining of Gear modulus M is 45, and workpiece greatest circle cone angle is 45 °, divides tooth precision＜5 ", 200～1500 rev/mins of main shaft gyration speed, operating ambient temperature is not limit; This equipment adopts digital program controlled system, and cutter adopts the carbide alloy coating technique, and cutting speed can reach 500～1000 meters/minute, has significantly shortened the process-cycle of workpiece, and work efficiency is more than tens times of legacy equipment, and is energy-saving and cost-reducing; This CNC milling machine calibration is accurate, and displacement is accurate, and it is reliable surely to operate steadily.

Description of drawings

Accompanying drawing is the utility model structural representation.

The specific embodiment

Referring to accompanying drawing; The utility model mainly by motor 9, vertically lathe bed 3, laterally lathe bed 2, rotary table 7, form to slide unit and guide rail, transmission shifting mechanism and digital control system in length and breadth; The cross slide 8-1 that is positioned at vertical lathe bed 3 bottoms matches with the cross rail 10-1 on horizontal lathe bed 2 planes; Vertical lathe bed 3 is laterally being moved horizontally on the lathe bed 2; Vertically the vertical guide rail 10-2 of lathe bed 3 sides matches with the vertical sliding table 8-2 that is fixed on gearbox 4 sidepieces, on gearbox 4 output shafts milling cutter 5 is housed, and milling cutter 5 moves up and down along vertical slide unit guide rail direction.

Rotary table 7 is made up of upper and lower watt of seat, connecting bolt, adjustment axle, chassis, worm gear, worm screw and chuck, and rotary table 7 constitutes certain angle of inclination with lower tile mounting base 7-8, and the inclination angle is in 45 °; The lower tile mounting base 7-8 of rotary table 7 parallels with horizontal lathe bed 2 and is fixed on the lathe base 1; Lower tile mounting base 7-8 and tile mounting base 7-1 connect as one through the connecting bolt 7-7 on adjustment axle 7-2 both sides; The joint close of upper and lower watt of seat just in time is positioned on the diameter line of adjustment axle 7-2; Upper and lower watt of seat is connected on the chassis 7-6 of rotary table 7 through adjustment axle 7-2; The worm gear 7-4 that is meshed with worm screw 7-3 is connected through bearing output shaft and chassis 7-6, and the chuck 7-5 that is used to clamp workpiece 6 and is conical gear is fixed on worm gear 7-4 end face.Be clipped in when workpiece 6 on the chuck 7-5 of rotary table 7, during according to the angle of inclination of the coning angle of workpiece adjustment rotary table, 7-7 unclamps with connecting bolt, adjusts behind the predetermined angular clamping screw again; The position of milling cutter 5 is according to the tooth depth of workpiece, and the adjustment vertical sliding table reaches requirement, and the milling cutter that runs up is made traverse motion at cross slide 8-1 along lathe bed workpiece is processed, and running is by the programme-control of digital control system.
