Abstract
The utility model relates to an automatic-adjusting bracket for a long shaft. The bracket comprises two supporting wheels, two shaft racks of the supporting wheel, a base bracket, wherein the two coplanar and homocentric supporting wheels are symmetrically and respectively mounted at the end parts of the two shaft racks of the supporting wheel in the radial direction of a supporting wheel shaft; the two shaft racks of the supporting wheel are respectively mounted on the base bracket and in two shaft sleeves coaxially; the two shaft sleeves are fixedly mounted on a shaft rack supporting plate which is mounted on the base bracket in parallel; a pin shaft is fixedly mounted at the corner part of the base bracket; and a long pin hole is formed on shaft rack supporting plate corresponding to the pin shaft which is embedded in the long pin hole. The self-adjusting bracket with simple structure and scientific and reasonable design can automatically adjust the deflection of the long shaft in the radial direction, ensures the processing accuracy of a lathe, and improves the quality level of processing workpieces of the long shaft.
Description
Technical field
The utility model belongs to the lathe of mechanical manufacturing field, especially a kind of major axis self-regulated support.
Background technology
When the machine tooling long axis workpiece, need be installed on the headstock long axis workpiece is coaxial, on the coaxial center bearing bracket that is erected on the guide rail in the processing part of major axis, undressed part needs coaxial being erected on the outer support of lathe.Because its concentricity of major axis of undressed part is relatively poor, therefore, adopts present fixed bracket can cause the bump of major axis to support, but also might cause damage to the precision equipment of headstock.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of self-regulating major axis self-regulated support of realizing is provided.
The purpose of this utility model is achieved in that
A kind of major axis self-regulated support, comprise support roller, support roller pedestal, base support, support roller is that two and coplane are homocentric, two support rollers are installed in supporting-roller shaft frame end portion by the supporting-roller shaft mirror respectively to symmetry, two support roller pedestals are installed on the base support, it is characterized in that: two coaxial respectively being installed in the axle sleeve of support roller pedestal, two axle sleeves are packed on the pedestal supporting plate, this pedestal supporting plate is installed in parallel on the base support, corner positions at base support is fixed with bearing pin, with the corresponding pedestal supporting plate of bearing pin on be shaped on the hole of having strong market potential, bearing pin is inlaid in the hole of having strong market potential.
And the following bottom of the support roller pedestal in axle sleeve is fixed with a nut, and the leading screw that its lower end is shaped on the four directions is installed in this nut engagement, and a thrust bearing is installed in axle sleeve and on the leading screw between the support roller pedestal.
And the described hole of having strong market potential is a horizontally set, and have strong market potential hole and the bearing pin thereof in pedestal supporting plate bight are provided with two at least, and are the diagonal angle setting.
Advantage of the present utility model and good effect are:
1, this self-regulated support adopts two homocentric support rollers to support major axis, and running status is good; And two support rollers are adjustable diametrically, are suitable for the major axis of various diameters.
2, this self-regulated support is packed on the pedestal supporting plate, and itself and base support are the movable installation of bearing pin diametrically, have realized the automatic adjustment diametrically of pedestal supporting plate and base support thus, can adapt to the major axis that has amount of deflection.
3, the utility model overall structure is simple, and design science is reasonable, can adjust the radially amount of deflection of major axis automatically, guarantees the machining accuracy of lathe, improves the quality level of long axis workpiece processing.
Description of drawings
Fig. 1 is front view of the present utility model (broken section);
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A portion structure enlarged drawing of Fig. 1
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described; Need to prove: present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of major axis self-regulated support comprises support roller 1, support roller pedestal 3, base support 6, and support roller is that two and coplane are homocentric, and two support rollers are installed in supporting-roller shaft frame end portion by supporting-roller shaft 2 mirrors respectively to symmetry, and two support roller pedestals are installed on the base support.Innovative point of the present utility model is: two coaxial respectively being installed in the axle sleeve 5 of support roller pedestal, and the mounting means of support roller pedestal and axle sleeve is:
The following bottom of the support roller pedestal in axle sleeve is fixed with a nut 9, and the leading screw 8 that its lower end is shaped on four directions 11 is installed in this nut engagement, makes the leading screw rotation by rotating the four directions, and the leading screw geared screw makes the support roller pedestal flexible.In order to make the leading screw operation sliding smooth, a thrust bearing 10 is installed in axle sleeve and on the leading screw between the support roller pedestal.
Two axle sleeves are packed on the pedestal supporting plate 4, this pedestal supporting plate is installed in parallel on the base support, its mounting means: the corner positions on base support is fixed with bearing pin 7, with the corresponding pedestal supporting plate of bearing pin on be shaped on the hole of having strong market potential, this hole of having strong market potential is a horizontally set, radially slides displacement so that the pedestal supporting plate drives support roller at base support.
Axially displaced for fear of the pedestal supporting plate, have strong market potential hole and the bearing pin thereof in bight are provided with two at least, and are the diagonal angle setting.
