Abstract
A vertical lathe headstock installment structure adopts a novel structure that the cylinder shape of a headstock and round holes of a lathe bed adopt small clearance fit, and the upper end of the headstock is fixed in the axis direction while the lower end is fixed in the radial direction. The installment structure is characterized in that a separating-type tapered expansion sleeve is adopted at the lower end of the headstock; an outer taper sleeve is matched with the lower end of the headstock body; the outer taper sleeve generates axial replacement through a screw arranged on a gland of the lathe bed leads, and generates radial deformation through the axial movement between the conical surfaces, thereby ensuring the reliable connection between the headstock and the lathe bed; different connection types of the upper and the low ends enable the headstock and the lathe bed to form a whole; and meanwhile, the processing difficulties and cost are reduced, the assembling difficulties are simplified, the stiffness of the vertical lathe spindle is improved, and the accuracy of the lathe is improved.
Description
Technical field
The utility model relates to the technology of Machine Tool field, and particularly a kind of structure that improves the lathe spindle rigidity, purpose are to improve the rigidity of vertical lathe spindle, reduce the difficulty of processing of Lathe Spindle Box and base installing hole, reduce processing cost, reduce assembly difficulty, improve lathe stability.
Background technology
As everyone knows, at present, main spindle box of numerical control vertical lathe all adopts separate type with bed piece, the rigidity of main spindle box depends on the rigidity that is connected of main spindle box and lathe bed to a great extent. the main spindle box of vertical lathe adopts the revolving body profile mostly, whole main spindle box adopts the suspension type installation to be connected with lathe bed, the main spindle box cylindrical shape adopts with the lathe bed circular hole and cooperates the rigidity that can guarantee main spindle box fully, but this will certainly improve the processing cost of main spindle box installing hole and main shaft casing, has also increased assembly difficulty simultaneously.But must cause the machine tool chief axis rigidity to descend as adopting the little matched in clearance increase of main spindle box cylindrical shape and lathe bed circular hole end face flange form screw to be connected, can't reach the requirement of vertical lathe spindle rigidity.
Summary of the invention
The purpose of this utility model is to provide a kind of novel vertical lathe spindle tank mounting structure, to overcome the deficiencies in the prior art, make its simple in structure, rationally distributed, good reliability, reduce the difficulty of processing of Lathe Spindle Box and base installing hole, reduce processing cost, reduce assembly difficulty.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of vertical lathe spindle tank mounting structure, its main spindle box adopt cylindrical shape and lathe bed circular hole to adopt little matched in clearance; And the main spindle box top axial is fixed, and lower end radially tensioner is fixed.
End face flange fixed form is adopted in main spindle box upper end, and axial cone match, the fixed form of tensioner are radially adopted in the lower end.
Cover and overcoat in the split type taper swelling cover installed in the main spindle box lower end, and interior cover and overcoat all are that the cross section is the triangular prism of right angled triangle, and two hypotenuses constitute split type taper swelling cover relatively, and gland is connected the main spindle box lower end by screw.
The utility model main spindle box adopts the revolving body profile, lathe bed installing hole and main spindle box adopt little matched in clearance, the sub-fraction inner hole surface of a lathe bed installing hole fine finishining upper surface and hole upper and lower end, main spindle box revolving body profile be the sub-fraction periphery of a fine finishining cylindrical upper and lower end and the flange face of upper end also.Main spindle box and lathe bed installing hole upper surface are fixed with screw axial, a split type tapered expansion set is adopted in the lower end, external conical sleeve is engaged in main shaft casing lower end, external conical sleeve makes external conical sleeve produce axial displacement by being installed in the screw on the gland on the lathe bed, produces radial deformation by the external tapered sleeve that moves axially between the conical surface, thereby guarantee that main spindle box is connected reliably with lathe bed, make the main shaft casing become as a whole, guaranteed the rigidity of whole main shaft, improved machine tool accuracy with lathe bed.
The beneficial effects of the utility model are, by adopting main spindle box cylindrical shape and lathe bed circular hole to adopt little matched in clearance, fixing and the lower end of main spindle box top axial is the new structure of fixed form radially, a split type tapered expansion set is adopted in the main spindle box lower end, external conical sleeve is engaged in main shaft casing lower end, external conical sleeve is by being installed in the screw on the gland on the lathe bed, make external conical sleeve produce axial displacement, produce radial deformation by the external tapered sleeve that moves axially between the conical surface, thereby guarantee that main spindle box is connected reliably with lathe bed, the different connected modes of upper and lower side, make main spindle box become as a whole with lathe bed, difficulty of processing and cost have also been reduced, simplified assembly difficulty, improve the rigidity of vertical lathe spindle, thereby improved machine tool accuracy.
Description of drawings
Fig. 1 is the utility model structural representation.
Figure number explanation: 1. main spindle box, 2. main shaft, 3. main shaft gyration bearing, cover in the 4. split type taper swelling cover, 5. split type taper swelling cover overcoat, 6. gland, 7. screw, 8. lathe bed, 9. screw.
The specific embodiment
As shown in Figure 1, main shaft 2 and main shaft gyration bearing 3 and other auxiliary component (figure part omitted) are contained within the main spindle box 1, main spindle box 1 upper end is connected with lathe bed 8 with screw 9 by the end face flange, main spindle box 1 is position and the little matched in clearance of lathe bed 8 radially, cover 4 in the split type taper swelling cover is adorned in main spindle box 1 lower end, make split type taper swelling overlap overcoat 5 axial displacements by the screw 7 that screws on the gland 5, with cover 4 cone match in the split type taper swelling cover, cover 4 produces radial deformation in split type taper swelling cover overcoat 5 and the split type taper swelling cover, thereby it is as a whole that split type taper swelling cover overcoat 5 and interior cover 4 of split type taper swelling cover and lathe bed 8 are connected into, and main spindle box 1 produced with lathe bed 8 be rigidly connected.
