Abstract
The invention relates to a static pressure spindle for a rotary workbench and belongs to the field of machines. A static pressure spindle is arranged, a plurality of oil chambers are uniformly formed on the surface of the static pressure spindle, and each oil chamber is communicated with an oil pump through an oil distributor. The static pressure spindle for the workbench has a simple structure and is applicable to various large-scaled rotary workbenches; and processing cost is reduced; assembly is more convenient and the service life is longer at the same time; a stable pressure oil film is formed during rotation; bearing capability is high; and friction force is small.
Description
Technical field
The present invention 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 invention provides a kind of rotary table hydrostatic spindle, form the voltage stabilizing oil film during rotation, carrying is big, and frictional force is little, has reduced processing cost, and assembling simultaneously is more easy, longer service life.
The technical solution adopted for the present invention to solve the technical problems 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 present invention also can realize by following measure: each oil pocket is connected with oil pump respectively through separator.
The invention has the beneficial effects as follows that the workbench hydrostatic spindle is simple in structure, be applicable to various large-scale rotary tables, and reduced processing cost that assembling simultaneously is more easy, longer service life forms the voltage stabilizing oil film during rotation, and carrying is big, and frictional force is little.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
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 present invention 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 present invention uses hydrostatic spindle 2 is installed in the rotary table 1, rotary table 1 is about 0.1mm with hydrostatic spindle 4 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.
