The utility model relates to the field of machine tools, in particular to a novel gate-type stand column. The novel gate-type stand column comprises a gate-type stand column body, a spindle box and a servo motor. Y-axis linear guide rails are arranged on the two sides of the exterior of the gate-type stand column body through symmetrical mechanisms respectively, the gate-type stand column body is connected with the spindle box, the spindle box is arranged in the gate-type stand column in the mode that a Y-axis ball screw penetrates through the spindle box, the upper end of the Y-axis ball screw is connected with the servo motor through a servo motor base, the lower end of the Y-axis ball screw is connected with a ball screw bearing pedestal on the gate-type stand column body, and the spindle box drives the Y-axis ball screw to rotate under the action of the servo motor, so that the spindle box is installed between the two guide rails of the stand column and moves up and down along the guide rails of the stand column in the gate-type stand column body. The symmetry principle is adopted for the novel gate-type stand column, and therefore bending resistance and torsion resistance of the stand column are enhanced; the problem that the stand column deforms unevenly when being heated is solved, positioning precision and repeated-positioning precision of the machine tools are improved, production efficiency is improved, and assembly and debugging time is shortened.
Description
technical field
The utility model relates to machine tool field, is specifically related to a kind of novel gantry column.
Background technology
The main spindle box of current domestic boring and milling machine is side hanging, and column is cylindricality, and main spindle box is in column one side; Deadweight column generation moment of flexure due to main spindle box, moves up and down with main spindle box, and the moment of flexure that column produces is variable; Column is biased in to be heated and can causes precision impaired while producing distortion.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple in structure, novel gantry column reasonable in design, easy to use, its adopts gate-type column is mainly that to have adopted symmetry principle to solve temperature distortion inhomogeneous, produces additional bending moment problem; Quiet rigidity, the dynamic stiffness of column and lathe have been improved; Gate-type column main spindle box moves in door, strengthens the cutting power of lathe, has improved efficiency, has reduced lathe use cost; Gate-type column is stressed evenly, and positioning precision and repetitive positioning accuracy can permanently keep.
For achieving the above object, the technical solution adopted in the utility model is:
Novel gantry column described in the utility model, comprise gate-type column, main spindle box, servomotor, described gate-type column takes symmetrical mechanism both sides external to be provided with Y-axis line slideway, and connect main spindle box, described main spindle box is passed main spindle box is arranged in gate-type column frame by Y-axis ball screw, described Y-axis ball screw upper end is connected with servomotor by servomotor seat, lower end is connected with ball screw bearing block on gate-type column, described main spindle box drives Y-axis ball screw to rotate under the effect of servomotor, thereby main spindle box is contained in the middle of column two guide rails, along column (Y-axis straight line) guide rail, in gate-type column, move up and down.
Further, described ball screw bearing block is arranged on gate-type column frame inside.
Further, described main spindle box inside is provided with boring axle, boring shaft extension enters to stretch out servomotor, main shaft rotating motor; By boring shaft extension, enter to stretch out servomotor and control putting in of boring axle and stretch out motion, main shaft rotating motor is controlled the rotation of main shaft.
Adopt after said structure, the utility model beneficial effect is: the utility model gate-type pillar construction is mainly to have adopted symmetry principle, has strengthened bending resistance, the anti-twisting property of column; Solved temperature distortion problem of non-uniform; Improve Machine Tool Positioning Accuracy and repetitive positioning accuracy; Enhance productivity and reduce the assembling and setting time.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in 2, novel gantry column described in the utility model, comprise gate-type column 1, main spindle box 2, servomotor 3, described gate-type column takes symmetrical mechanism both sides external to be provided with Y-axis line slideway 4, and connect main spindle box 2, described main spindle box 2 is passed main spindle box 2 is arranged in gate-type column 1 by Y-axis ball screw 5, described Y-axis ball screw 5 upper ends are connected with servomotor 3 by servomotor seat 7, lower end is connected with ball screw bearing block 6 on gate-type column 1, described main spindle box 2 drives Y-axis ball screw 5 to rotate under the effect of servomotor 3, thereby main spindle box 2 is contained in the middle of column two guide rails 4, along column guide rail 4, in gate-type column 1, move up and down.
Described ball screw bearing block 6 is arranged on gate-type column frame 1 inside.
Described main spindle box 2 inside are provided with boring axle 8, boring shaft extension enters to stretch out servomotor 9, main shaft rotating motor 10; By boring shaft extension, enter to stretch out servomotor 9 and control putting in of boring axle 8 and stretch out motion, main shaft rotating motor 10 is controlled the rotation of main shafts.
In use, door type structure column has adopted symmetrical structure to the utility model, and main spindle box 2 upper and lower motion in the middle of column two guide rails 4, has improved the rigidity of structure greatly.In addition, main spindle box 2 is to position from the inner side of left and right two guide rails 4, and the alignment of shafts displacement that thermal deformation produces is limited in vertical direction, therefore, can pass through the compensation to Y-axis ball screw 5, reduces the impact of thermal deformation, and thermal symmetry is good.Main spindle box 2 is contained in the middle of column two guide rails 4, along column guide rail 4, moves up and down.When main shaft is subject to cutting force, the application point of power is in column central authorities, so column is subject to the large minimizing of factor of torsional forces, and the symmetric shape of column, has strengthened intensity greatly in addition.The advantage of gate-type pillar construction is good rigidly.Gate-type pillar construction becomes thermal tracking form, and this has just reduced the impact of thermal deformation; Good stability, adopts frame structure to arrange because column is whole, and the intrinsic frequency of bending resistance, torsional rigidity and the member of column is all improved; Avoid column to resonate simultaneously.The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
