Abstract
The invention provides a linear feeding mechanism for a machine tool. The linear feeding mechanism causes a bearing capacity to be strong and a motion to be stable and has a high response speed. The linear feeding mechanism comprises an upper sliding plate and a lower base, wherein the bottom of the upper sliding plate is tightly connected to a guide rail; the guide rail is embedded in a guide rail slot of the lower base; the bottom of the upper sliding plate is supported on the lower base; the linear feeding mechanism is characterized in that a linear motor is mounted in a cavity between the upper sliding plate and the lower base; a primary of the linear motor is tightly connected to the bottom of the upper sliding plate; a secondary of the linear motor is tightly connected to the upper end face of the lower base; the linear motor is located in a groove which is formed by upper guide rails on two sides of the linear motor; the upper guide rails are tightly connected to the lower base; the primary of the linear motor is supported on the secondary of the linear motor; a throttle is arranged in the upper sliding plate; oil paths are arranged in the upper sliding plate and the guide rail; oil cavities are arranged between friction surfaces of the guide rail, the lower base, between friction surfaces of the upper sliding plate and the lower base, between friction surfaces of the upper sliding plate and the upper guide rails as well as between friction surfaces of the guide rails and the upper guide rail; and the throttle is respectively communicated with the oil cavities through the oil paths.
Description
Technical field
The present invention relates to the technical field of machine tool structure, be specially the straight-line feed mechanism of lathe.
Background technology
Along with industrial expansion, non-circular hole class part is more and more, requires feed mechanism to have the quick and high rigid characters of response.Existingly realize that through ball screw its bearing capacity of structure of straight-line feed is little, the location is not accurate, and bumpy motion, response speed is slow.
Summary of the invention
To the problems referred to above, the invention provides the straight-line feed mechanism of lathe, it makes that bearing capacity is big, motion is steady, and response speed is fast.
The straight-line feed mechanism of lathe; Its technical scheme is such: it comprises top slide plate, bottom base; Slide plate bottom, said top is fastenedly connected guide rail, and said guide rail is embedded in the guide-track groove of said bottom base, and the bottom supporting of said top slide plate is base in said bottom; It is characterized in that: in the cavity between said top slide plate, the bottom base linear electric motors are installed; The elementary bottom that is fastenedly connected said top slide plate of said linear electric motors, the secondary upper surface that is fastenedly connected said bottom base of said linear electric motors, said linear electric motors are positioned at the formed cell body of upper rail of its both sides; Said upper rail is fastenedly connected said bottom base; Said linear electric motors elementary is supported on the secondary of said linear electric motors, and said top slide plate set inside has flow controller, and said top slide plate, guide rail set inside have oil duct; Be provided with oil pocket between said guide rail, bottom base, top slide plate, upper rail rubbing surface each other, said flow controller is communicated with said oil pocket respectively through said oil duct.
It is further characterized in that: be provided with the facade oil pocket between the rubbing surface of the guide-track groove of said guide rail, bottom base;
Be provided with horizontal oil pocket between the rubbing surface of said top slide plate, bottom base;
Be provided with horizontal oil pocket between the rubbing surface of said top slide plate, upper rail;
Be provided with horizontal oil pocket between the rubbing surface of said upper rail, guide rail.
After adopting structure of the present invention, because linear electric motors make top slide plate moving linearly on the base of bottom through the magnetic force that primary and secondary produces, it is simple in structure; Transmission efficiency is high, and response speed is fast, accurate positioning; In addition; Said slide plate set inside has flow controller, and said slide plate, guide rail set inside have oil duct, is provided with oil pocket between said guide rail, bottom base, top slide plate, upper rail rubbing surface each other; Said flow controller is communicated with said oil pocket respectively through said oil duct; Make the guide rail in this structure then adopt hydrostatic slideway, and make the top slide plate all reach balance in the horizontal and vertical directions through regulating flow controller, hydrostatic slideway makes that total has that coefficient of friction is little, long service life, be difficult for creeping, kinematic accuracy is high, bearing capacity is big, absorbing property is good, motion steadily.
