Abstract
The invention discloses a changeable suspension extending axial structure for a machine tool column. The changeable suspension extending axial structure comprises a fixed plate, a movable plate, a column, and a main shaft which is arranged inside the column, wherein the fixed plate is provided with a fixed rail, a slide rail is arranged below the fixed plate, the column is provided with a column rail, the column rail and the fixed rail are mounted in a matching manner, therefore the column can move up and down along the fixed plate, two side faces of the movable plate are respectively provided with slide blocks that are respectively a first slide block and a second slide block, the first slide block is installed on the slide rail, and the second slide block is arranged on the column rail. The changeable suspension extending axial structure for a machine tool column is advantaged by amelioration of the unfavorable situation that offset relative to the fixed machine is generated by the free end of the column due to bending moment strength caused by the processing procedure.
Description
Technical field
The present invention relates to a kind of toolroom machine column variable overhang axial structure.
Background technology
The structure that overhangs of toolroom machine column is toolroom machine common structure, overhanging in structure of conventional tool machine, toolroom machine column is positioned its machining spindle, column is connected with the fixedly board of toolroom machine with a rail structure, provide main shaft to move both vertically and the ability of locating, rail structure consists of a pair of the first track and a pair of the second track that is fixed on column that is fixed on board.When main shaft is subject to the driving force of a vertical direction, column just take with board the displacement that sliding track mechanism produces vertical direction as interface.
The Support Position of column is the upper end to column by the lower end of column, makes the main shaft of column and column inside form a cantilever position.Railroad no doubt helps the position stability while promoting column slip.Yet, when column internal spindle moves down and carries out it to outside workpiece processing operation, resistance and main shaft from workpiece form a moment, now due to board by sliding track mechanism for the support of column only and in the upper end of column, aforesaid moment loading is when forming the column of cantilever position, produce a moment of flexure strength, cause column free end with respect to fixedly board generation skew, thereby affect its internal spindle for the precision of outside workpiece processing.
Summary of the invention
The technical issues that need to address of the present invention are just to overcome the defect of prior art, and a kind of toolroom machine column variable overhang axial structure is provided, and it can improve column free end and with respect to fixing board, produce the unfavorable situation being offset because of the moment of flexure strength that causes of processing.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of toolroom machine column variable overhang axial structure, comprise fixed head, portable plate, column, be arranged at the main shaft in column; On described fixed head, be provided with trapped orbit, fixed head below is provided with a sliding rail; On described column, be provided with column track, the installation that matches of described column track and trapped orbit, makes column along the upper and lower activity of fixed head; Two sides of portable plate are respectively arranged with a slide block, are respectively the first slide block and the second slide block; The first slide block is installed on sliding rail, and the second slide block is installed on column track.
Column track tail end is provided with a stopping means, is used for limiting the stroke of the second slide block.
Sliding rail tail end is provided with a stopping means, is used for limiting the first slide block with respect to the stroke of sliding rail.
When column and main shaft are subject to thrust in the vertical direction, column track moves at column axial direction from top to bottom with respect to trapped orbit, the first slide block on sliding rail moves downward together with portable plate with the second slide block, so, free end support place of column will move down a segment distance, support place just can better be supported column, thereby improves the Moment Influence that conventional overhang axial structure brings because of machining, thereby improves machining accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the invention provides a kind of toolroom machine column variable overhang axial structure, comprise fixed head 1, portable plate 2, column 3, be arranged at the main shaft 4 in column; On described fixed head, be provided with trapped orbit 5, fixed head below is provided with a sliding rail 6; On described column, be provided with column track 7, the installation that matches of described column track and trapped orbit, makes column along the upper and lower activity of fixed head; Two sides of portable plate are respectively arranged with a slide block, are respectively the first slide block 8 and the second slide block 9; The first slide block is installed on sliding rail, and the second slide block is installed on column track.
Column track tail end is provided with a stopping means 10, is used for limiting the stroke of the second slide block.
Sliding rail tail end is provided with a stopping means 11, is used for limiting the first slide block with respect to the stroke of sliding rail.
When column and main shaft are subject to thrust in the vertical direction, column track moves at column axial direction from top to bottom with respect to trapped orbit, the first slide block moves downward together with portable plate with the second slide block, so, free end support place of column will move down a segment distance, support place just can better be supported column, thereby improves the Moment Influence that conventional overhang axial structure brings because of machining, thereby improves machining accuracy.Finally it should be noted that: obviously, above-described embodiment is only for example of the present invention is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection scope of the present invention.
