Abstract
The utility model relates to a hydrostatic spindle for rotary worktables, which belongs to the field of machines. A plurality of oil cavities are arranged on the surface of the hydrostatic spindle uniformly and respectively communicated with an oil pump through an oil distributor. The hydrostatic spindle for rotary worktables is simple in structure and suitable for various large-sized rotary worktables while processing cost is reduced. The hydrostatic spindle is simpler in assembly and longer in service life. As a pressure stabilized oil film is formed when the hydrostatic spindle rotates, the hydrostatic spindle has high bearing and low friction force.
Description
Technical field
The utility model relates to machine tool field, especially a kind of hydrostatic spindle that is used for large-scale rotary table.
Background technology
As everyone knows, the large-scale rotary table of traditional machine tool must be set with main shaft bearing between rotary table and main shaft when turning around main axis rotation, employed main shaft bearing is a kind of mechanical type roller bearing, bearing diameter is big, in addition because the bearing quality of fit requires high, increased processing cost on the one hand, assembling is wasted time and energy on the other hand.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of rotary table hydrostatic spindle, forms the voltage stabilizing oil film during rotation, and carrying is big, and frictional force is little, has reduced processing cost, and assembling simultaneously is more easy, longer service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotary table hydrostatic spindle, be provided with hydrostatic spindle, and the hydrostatic spindle surface evenly is processed with a plurality of oil pockets.
The utility model also can be realized by following measure: each oil pocket is connected with oil pump respectively through separator.
The beneficial effects of the utility model are, the workbench hydrostatic spindle is simple in structure, are applicable to various large-scale rotary tables, and have reduced processing cost, and assembling simultaneously is more easy, and longer service life forms the voltage stabilizing oil film during rotation, and carrying is big, and frictional force is little.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is this user mode schematic diagram.
1. rotary tables among the figure, 2. hydrostatic spindle, 3. oil pocket.
The specific embodiment
In Fig. 1, Fig. 2, the utility model is provided with hydrostatic spindle 2, and hydrostatic spindle 2 surfaces evenly are processed with a plurality of oil pockets 3, and the quantity of oil pocket 3 will generally be no less than 4 according to the diameter decision of main shaft 2, and each oil pocket 3 is connected with oil pump respectively through separator.Independent oil pump station fuel feeding, pressure oil are by separator, and corresponding with it oil pocket 3 connects, and guarantees constant current amount fuel feeding, and has reduced processing cost, and assembling is more easy simultaneously.When the utility model uses hydrostatic spindle 2 is installed in the rotary table 1, rotary table 1 is about 0.1mm with hydrostatic spindle 2 gaps.
Claims (2)
1. a rotary table hydrostatic spindle is provided with hydrostatic spindle, it is characterized in that the hydrostatic spindle surface evenly is processed with a plurality of oil pockets.
2. according to the described rotary table hydrostatic spindle of claim 1, it is characterized in that said each oil pocket is connected with oil pump respectively through separator.
