The adjustment of traditional machine tool headstock spindle axis needs the techniques and methods of specialty, the adjustment operation of the person that is not suitable for normal user operation, therefore need to invent and a kind ofly can meet that domestic consumer is simple and convenient, the device of rapid adjustment main-shaft axis, make it meet the requirement of common operator.
Summary of the invention
The purpose of this utility model is the deficiency for original lathe headstock main-shaft axis adjustment operation, provide a kind of rational in infrastructure, simple, easy to operate main-shaft axis adjusting device is installed.
The purpose of this utility model can be achieved through the following technical solutions:
Machine tool chief axis axis trimming device, comprises flat main spindle box and bed piece; Fixedly mount a convex adjustment block in the side bottom of flat main spindle box, its projection exceeds flat main spindle box baseplane; Fixedly mount a recessed adjustment block in the position that bed piece side surface upper part is corresponding with convex adjustment block, the projection of its recessed portion and convex adjustment block matches; The left and right sides boss of recessed adjustment block is laterally provided with screwed hole, is relatively screwed with adjustment bolt in two screwed holes, withstands on the left and right sides of the intermediate flange of convex adjustment block; In flat main spindle box baseplane, place is equipped with an alignment pin, and alignment pin one end is sold in bottom flat main spindle box, and other end pin is in bed piece.
The side bottom of flat main spindle box fixedly mounts convex adjustment block by fixed-use bolt.
Bed piece side surface upper part fixedly mounts recessed adjustment block by fixed-use bolt.
Fixed-use bolt adopts hexagon socket head cap screw, and adjustment bolt adopts outer-hexagonal bolt.
The screwed hole that the left and right sides boss of recessed adjustment block is laterally provided with is symmetrical.
Described alignment pin is positioned on the spindle hole center conllinear of main spindle box and perpendicular to flat main spindle box baseplane place.
The beneficial effects of the utility model are:
The utility model is simple and reliable for structure, it is easy to operate to adjust; There is good operability, reliability, and there is excellent reasonability and practicality; Indirectly simplify the body structure of former main spindle box for axis trimming.

Detailed description of the invention
Below in conjunction with accompanying drawing, for original main-shaft axis adjust structure and specific embodiment, illustrate the utility model further.
As shown in Fig. 3, Fig. 4-1, Fig. 4-2 and Fig. 5, the utility model machine tool chief axis axis trimming device, comprises flat main spindle box 5 and bed piece 2.Fixedly mount a convex adjustment block 6 in the side bottom of flat main spindle box 5 by fixed-use bolt 4, its projection exceeds flat main spindle box 5 baseplane.In the position that bed piece 2 side surface upper part is corresponding with convex adjustment block 6, fixedly mount a recessed adjustment block 8 by fixed-use bolt 4, the projection of its recessed portion and convex adjustment block 6 matches.On the left and right sides boss of recessed adjustment block 8, lateral symmetry is provided with screwed hole, is relatively screwed with adjustment bolt 7 in two screwed holes, withstands on the left and right sides of the intermediate flange of convex adjustment block 6, makes convex adjustment block 6 together with recessed adjustment block 8 secure fit.As better embodiment, fixed-use bolt 4 can adopt hexagon socket head cap screw, and adjustment bolt 7 adopts outer-hexagonal bolt.In addition, an alignment pin 9 is equipped with at the spindle hole 10 center conllinear with main spindle box 5 perpendicular to flat main spindle box 5 baseplane place.Alignment pin 9 one end is sold in bottom flat main spindle box 5, and other end pin is in bed piece 2.When convex adjustment block 6 and recessed adjustment block 8 are also unassembled, flat main spindle box 5 can rotate along alignment pin 9 for axle does in unfixed situation.When convex adjustment block 6 and recessed adjustment block 8 are assembled together, add the effect of alignment pin 9, flat main spindle box 5 is together with bed piece 2 strong bonded.
Assembling process of the present utility model is:
When flat main spindle box 5 is not when locking, can rotate around alignment pin 9; Alignment pin 9 is in through spindle hole 10 center and on straight line perpendicular to flat main spindle box 5 bottom surface, and two ends are on the mating surface of bed piece 2 and flat main spindle box 5 respectively.Convex adjustment block 6 is fixed on the side of flat main spindle box 5 by set bolt 4, and makes its projection exceed the baseplane of flat main spindle box 5.Recessed adjustment block 8 is fixed on the side of bed piece 2 by set bolt 4, and matches with convex adjustment block 6.The left and right two that adjustment bolt 7 is symmetrically placed in recessed adjustment block 8 is respectively erected in the screwed hole of boss.When needing to adjust main-shaft axis and machine tool guideway parallelism error on the horizontal level, by wherein one (or the left side or the right) in adjustment adjustment bolt 7, it is made to withstand the flange of convex adjustment block 6, and drive flat main spindle box 5 to do the angular deflection of main-shaft axis around alignment pin 9, by the testing tool such as plug and dial gauge with the use of, main-shaft axis and machine tool guideway parallelism error is on the horizontal level made to meet original machine tool accuracy when requiring, locking adjustment bolt 7, then the fixed-use bolt 4 that main spindle box 5 is combined with bed piece 2 is in succession locked, whole assembly work completes.
