Along pedestal 1 bottom even multiple foots pad 9 are set, base rail 2 and lathe bed 3 are fixedly installed on pedestal 1.Base rail 2
For two closed slides, same one end of two parallel base guide rails is respectively provided with a servo longitudinal motor and (not shown in figure, longitudinally schemed
Perpendicular to paper direction in 1), a screw mandrel, one end and the servo longitudinal electricity of screw mandrel are respectively provided with the top of two parallel base guide rails
The rotary shaft of machine is connected, and the bottom of two columns 10 is respectively fixedly connected by sliding block with feed screw nut, in the outer of two base rails 2
One graduated scale is respectively set along longitudinal direction on side.Column guide rail is respectively provided with the side of two columns 10, back timber 7 is set by sliding block
On column guide rail, a support 11 is respectively provided with the outside of two columns, the bottom of support 11 is fixed with reinforcement, each support 11
Upper that a hoist cylinder 12 is fixedly installed respectively, the piston rod of hoist cylinder 12 is connected with back timber 7, can drive back timber about 7
It is mobile.Being horizontally disposed with back timber 7 has convex guide rail and ball screw, and ball screw is by the first servomotor drive installed in right-hand member
It is dynamic, slide is installed, the slide back side is installed with nut seat, and nut seat is enclosed on the ball screw nut of back timber 7 on convex guide rail
On be fixedly connected, when the first servomotor drive screw is rotated, feed screw nut drives slide left and right level fortune on back timber 7
It is dynamic.The recessed guide rail and ball screw of vertical direction are housed, the second servomotor 8 is arranged on slide upper end, in slide on slide
Main spindle box slide unit is installed, the main spindle box slide unit back side is installed with nut seat, and nut seat is enclosed on the rolling on slide on recessed guide rail
It is fixedly connected on ballscrew nut, when the drive screw of the second servomotor 8 is rotated, feed screw nut drives main spindle box slide unit upper and lower
Vertical movement.It is provided with main spindle box slide unit inside spindle motor 6, replaceable main spindle box 5 and tool heads 4, replaceable main spindle box 5
Vertically disposed to have power transmission shaft, the first main shaft and the second main shaft, replaceable main spindle box 5 is provided with upper and lower end plate, upper and lower end
The mounting hole for installing power transmission shaft, the first main shaft and the second main shaft is correspondingly arranged on plate, wherein for the first main shaft and
The mounting hole of two main shafts be correspondingly arranged on upper and lower end plate it is multipair, between adjusting between the first main shaft and the second main shaft
Away from, the upper end of power transmission shaft is connected by shaft coupling with the output shaft of spindle motor 6, and power transmission shaft is provided with a central gear, the
A travelling gear being meshed with above-mentioned central gear is respectively equipped with one main shaft and the second main shaft.The tool heads 4 include
One roughing heads and a fine grinding head, it is connected by cutter clamping device with the first main shaft and the second main shaft respectively.Lathe bed 3 is set
It is placed between two base rails 2, the replaceable main spindle box 5 for accommodating multiple different Dimension Types is provided with the side of lathe bed
Cabinet, the top of lathe bed 3, which is provided with to be provided with two longitudinal slide rails, slide rail, vertically moves workbench.
It is a kind of preferred for the design method of the mounting hole for being used for the first main shaft and the second main shaft of replaceable main spindle box 5
Scheme be that the center of circle of multiple mounting holes is distributed in the concentric circles of the mounting hole for power transmission shaft on end plate, so adjust
Spacing between whole first main shaft and the second main shaft to adjust during the spacing between two bistriques, no matter the first main shaft and second
Which mounting hole main shaft selection is fixed in, can ensure the first main shaft, on travelling gear and power transmission shaft on the second main shaft
Central gear has constant and stable meshing relation, does not influence power to transmit.
For replaceable main spindle box 5, in order to increase the alternative of the spacing between the first main shaft and the second main shaft, lathe
The replaceable main spindle box 5 of a variety of different Dimension Types is specially equipped with, multiple replaceable main spindle boxes 5, which are deposited on the side of lathe bed, to be set
In the cabinet put, to meet different work pieces process demands.
During work, by flat work pieces clamping vertically moving on workbench on lathe bed 3, according to the plane face to be ground
Long-pending size, selects the replaceable main spindle box 5 of suitable dimension, and the area of plane to be for example ground is larger, then general bistrique is straight
It is larger that footpath is selected, and should typically select the first main shaft and the larger replaceable main spindle box 5 of the second main shaft spacing, then adjust choosing
The spacing between the first main shaft and the second main shaft in fixed replaceable main spindle box 5, main spindle box is fixed on by replaceable main spindle box 5
Precalculated position on slide unit.By adjusting the motion of each guide rail and hoist cylinder, tool heads 4 and flat work pieces are adjusted to add
Station is put, and is then processed process.Processing initial stage, roughing heads first contact workpiece surface and are processed, fine grinding head first avoid plus
Work surface, with the progress of processing, roughing heads are while thick grinding made above, and fine grinding head contact is added by roughing heads
The surface that work is crossed, by that analogy, is gradually completing the processing of whole workpiece surface.
It is preferred that, lathe of the invention also includes the clamping device for flat work pieces, and clamping device is fixed on longitudinal shifting
