Abstract
The invention discloses a numerical radial revolving knife device. A servo motor is fixed to one side of the box. A ball screw and a ball screw nut are located in the box. One end of the ball screw is fixed to an output shaft of the servo motor, and the other free end of the ball screw goes deep into a hollow part of a sliding sleeve. The ball screw nut is fixed to one end of the sliding sleeve. A pull rod is fixed to the other end of the sliding sleeve through an adapter. A guiding key is fixed to the sliding sleeve, contact points of proximity switches stretches out of the guiding key, and the feed proximity switch and the retreat proximity switch are fixed to a protection sleeve arranged outside the sliding sleeve in a sleeving manner. A movable groove of the guiding key is formed in the inner hole wall of the protection sleeve. According to the numerical radial revolving knife device, knife feed is stable, the machining size of machined parts is adjusted at will and controlled through programming at will, and the size requirement can be accurately met. Machining of part channeling, end face finish turning and chamfering and machining of hook faces, special-shaped faces and other special faces can be achieved, and the application range is wide.
Description
Technical field
The present invention relates to a kind of numerical control radially long knife system, particularly relate to one and can realize part grooving, finish turning end face and chamfering, the numerical control of the processing such as processing curve, shaped face radially long knife system.
Background technology
The conventional long cutter mechanism of radial direction is generally hydraulic jack control, and hydraulic jack cylinder diameter is little, oil pressure causes greatly feed velocity too fast, and cylinder diameter is big, oil pressure is little, is easily caused hydraulic jack and creeps；It is, what hydraulic jack controlled directly to show is exactly that feed is unstable, processing dimension is inaccurate, and the range of work is little, for some special, as curved surface, many boss shaped face can only use forming cutter to process.
Summary of the invention
The purpose of the present invention solves the above-mentioned problems in the prior art exactly, there is provided a kind of feed stable, part to be processed processing dimension arbitrarily adjusts, arbitrarily controlled by programming, accurately reach dimensional requirement, part grooving, finish turning end face and the processing of special of chamfering, processing curve and shaped face etc. can be realized, the numerical control having wide range of applications radially long knife system.
For achieving the above object, the technical solution of the present invention is: a kind of numerical control radially long knife system, it includes servomotor, ball-screw, ball-screw nut, sliding sleeve and pull bar；Servomotor is fixed on the side of casing, ball-screw and ball-screw nut and is positioned at casing；One end of ball-screw is fixed on the output shaft of servomotor, and another free end gos deep into the hollow interior of sliding sleeve；Ball-screw nut is fixed on one end of sliding sleeve；The other end of sliding sleeve is fixed with pull bar by jointer；Feather key is fixed on sliding sleeve, and it stretches out the contact of proximity switch, and feeding is fixed on outside sliding sleeve, with retrogressing proximity switch, the protection overlapped and puts；The loose slot of feather key is had on protection set inner hole wall.
The structure that one end of ball-screw described above is fixed on the output shaft of servomotor is: one end of ball-screw is fixed on one end of expansion sleeve shaft coupling, and the other end of expansion sleeve shaft coupling is fixed on the output shaft of servomotor.Ball-screw is fixed on the output shaft of servomotor by expansion sleeve shaft coupling, and expansion sleeve shaft coupling can eliminate the radial clearance between servomotor and ball-screw, makes transmission more stable.
Ball-screw described above is fixed the end of end and is also supported on cabinet wall by ball screw support；Ball screw support includes bracer and the two groups of bearing group being made up of deep groove ball bearing and thrust bearing that outer wall is fixed on cabinet wall；Ball-screw is fixed the end of end and is fixed in the centre bore of a bracer by two groups of bearing group, and two deep groove ball bearings of two groups of bearing group deviate from, and two thrust bearings are close.Ball-screw is fixed the end of end and is used the assembling form of two groups of deep groove ball bearings and thrust bearing cooperation to be supported in bracer, and the stability maintenance making the fixing end of ball-screw is more preferable.
Ball-screw described above is double nut ball-screw.Double nut ball-screw-transmission efficiency is high.
It is dynamic that the rotary motion of motor is changed into straight line by the ball-screw of the present invention and ball-screw nut.The present invention uses ball-screw and Serve Motor Control, and feed is stable.Radially rimmer knife amount arbitrarily can adjust by adjusting feeding and retrogressing proximity switch distance, so processing dimension can arbitrarily adjust, controls by programming is random, can accurately reach dimensional requirement.The tooth bar selected as required and tooth block can be installed on pull bar, tooth block selects the cutter that the different processing according to processing workpiece need is installed, part grooving, finish turning end face and the processing of special of chamfering, processing curve and shaped face etc. can be completed, have wide range of applications.
