Description
Technical field
The present invention relates to milling-boring machine technical field, more particularly, to a kind of benefit applied to milling-boring machine spindle thermal
Repay mechanism.
Background technology
For the heavy duty machine tools of the class of milling-boring machine one, during operation, cutting workpiece, the part such as main spindle box, ram, main shaft
Because stress causes the change of lathe power system, caused the heat that machine tool component occurs by frictional heat, cutting heat and variation of ambient temperature etc.
Deformation, all can cause the relative position between machine tool component to change, destroy the accuracy of its relative motion, make the several of lathe
What precision, control accuracy and machining accuracy etc. changes, the overall performance of final reduction lathe.
Milling-boring machine main spindle box, ram deformation are analyzed as shown in figure 1, dotted line is the situation after deformation, deformation master in figure
If because ram can produce heat in cutting feed and main shaft rotary course, the heat is applied on ram, its length side
To can occur thermal stretching.
The content of the invention
It is an object of the invention to the above mentioned problem for solving prior art appearance is hot applied to milling-boring machine main shaft there is provided one kind
, there is thermal stretching by setting canonical measure bar, displacement ring and displacement transducer to solve milling-boring machine main shaft in the compensation mechanism of elongation
The problem of.
A kind of compensation mechanism applied to milling-boring machine spindle thermal, it is characterised in that：Including canonical measure bar, displacement ring
And displacement transducer, the canonical measure bar is arranged on by clamping jaw in the inner hole of spindle of main spindle box, using indium Steel material, its line
Coefficient of expansion very little compared with ram, its left end is threadedly secured in main spindle box endoporus, and right-hand member is free, and passes through 4 pins
The change in displacement of canonical measure pipe can be delivered on the displacement ring outside main shaft by nail, and displacement ring has displacement transducer at any time
Detect change in displacement.
The bearing of main spindle box can produce amount of heat in high-speed rotation, and the heat is applied on main shaft, its length
Thermal stretching can occur for direction, at this moment, and change in displacement occurs relative to main shaft in the right-hand member of canonical measure pipe, and displacement transducer is logical
This variable quantity can be detected by crossing displacement ring, and transfer data to digital control system, and digital control system will subtract standard after data reduction
Measurement pipe itself by thermal expansion length, its difference be main shaft by thermal expansion length, last digital control system control axis feeding is watched
Motor is taken, driving ball-screw drives main shaft to move backward the difference, that is, realizes the compensation to spindle thermal.With it is existing
Technology is compared, and the present invention perfect can solve problem above, and it is simple to possess making, it is easy to the advantages of operating.
Brief description of the drawings

Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
The structural representation of the present invention is as shown in Figure 2.A kind of compensation mechanism applied to milling-boring machine spindle thermal, it is special
Levy and be：Including canonical measure bar 3, displacement ring 5 and displacement transducer 4, the canonical measure bar 3 is arranged on master by clamping jaw 6
In the inner hole of spindle of axle box 1, using indium Steel material, its linear expansion coefficient very little compared with ram, its left end is threadably secured
In the endoporus of main spindle box 1, right-hand member is free, and the change in displacement of canonical measure pipe can be delivered to outside main shaft by 4 pins
On the displacement ring 5 in face, and displacement ring 5 has displacement transducer 4 to detect change in displacement at any time.Displacement ring 5 and the section of canonical measure bar 3
Figure is as shown in Figure 3.
Compensation principle of the present invention：The bearing of main spindle box 1 can produce amount of heat in high-speed rotation, heat effect
Onto main shaft, thermal stretching can occur for its length direction, at this moment, and the right-hand member of canonical measure pipe occurs that displacement becomes relative to main shaft
Change, and displacement transducer 4 can detect this variable quantity by displacement ring 5, and digital control system is transferred data to, digital control system will
Subtracted after data reduction canonical measure pipe itself by thermal expansion length, its difference be main shaft by thermal expansion length, last numerical control
System controls axis feeding servomotor, and driving ball-screw drives main shaft to move backward the difference, that is, realized to main shaft
The compensation of thermal stretching.
Although being described in conjunction with the accompanying embodiments of the present invention, patent owner can be in appended claims
Within the scope of make various deformations or amendments, as long as no more than the present invention claim described by protection domain, all should
Within protection scope of the present invention.
