Abstract
The utility model discloses a gear machine tool unloading type static pressure rotating table, which comprises a supporting body and a rotating body arranged on the supporting body. The supporting body and the rotating body are matched in contacting and rotating mode. An annular upper oil cavity is arranged on an upper contact face of the supporting body, and an upper oil channel communicated with the upper oil cavity is arranged on the supporting body. The upper contact face and the lower contact face of the supporting body and the rotating body are matched in rotating mode, an annular lower oil cavity is arranged on a lower contact face of the supporting body, and a lower oil channel communicated with the lower oil cavity is arranged on the supporting body. During use, pressure oil is input to annular oil cavities by using an external oil pressure system, the stable pressure oil forms a lubricating oil film on the contact faces between the rotating body and the supporting body so that an unloading effect is achieved and simultaneously friction between the rotating body and the supporting body is greatly reduced. Rotation is easy, metal fine powder produced through hard friction is greatly reduced, and service life of a machine tool table is greatly prolonged.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of discharging type static pressure workbench of lathe.
Background technology
In machine tool field, especially need process the lathe of big parts for some, its workbench also needs continuous rotation when carrying huge weight, satisfy the processing that parts to be processed are not allowed the position.In order to improve machine tool accuracy and whole stability, a plurality of notch cuttype contact-making surfaces are set usually.In the prior art, closely contact between workbench rotary body and the supporter, during the rotation of workbench rotary body and be hard friction between the supporter; Frictional resistance is big, not only needs more powerful drive motors, and is uneconomical; And hard friction produces lemel easily on contact-making surface, can not in time remove, and further accelerates the friction between two working faces easily; Smooth working face is destroyed, reduce the service life of platen.
The utility model content
In view of this, the purpose of the utility model provides a kind of gear machine discharging type static pressure rotary table, utilizes the static pressure principle, reduces the frictional force between workbench rotary body and the supporter, reduces cost, and improves the service life of platen.
The purpose of the utility model realizes through following technical scheme: a kind of gear machine discharging type static pressure rotary table; Comprise supporter and be positioned at the rotary body on the supporter; Be rotatably assorted for contact between supporter and the rotary body; Annular upper oil cavitie is set on contact-making surface on the supporter, the last oil duct that is connected with upper oil cavitie is set on the supporter.
Further, for two up and down contact-making surface formulas are rotatably assorted, annular lower oil cavitie is set on the following contact-making surface of supporter between said supporter and the rotary body, the following oil duct that is connected with lower oil cavitie is set on the supporter.
The beneficial effect of the utility model: the described discharging type static pressure of the utility model workbench owing on the contact-making surface of supporter, annular oil cavity is set, is provided with the oil duct that is connected with annular oil cavity simultaneously on supporter; During use; Utilize oil outer pressing system input pressure oil in annular oil cavity, the contact-making surface of pressure stable oil between rotary body and supporter forms lubricating oil film, when playing " off-load " effect; Also reduced the frictional force between the two greatly; Rotation is easy, and has significantly reduced the lemel that hard friction brings, and has prolonged the service life of platen greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Fig. 1 is the structural representation of the utility model.As shown in the figure: the gear machine discharging type static pressure rotary table of present embodiment; Comprise supporter 1 and be positioned at the rotary body on the supporter; For contact is rotatably assorted, present embodiment is that upper and lower pair of contact-making surface formula is rotatably assorted between supporter and the rotary body, promptly is provided with upper and lower two contact-making surfaces on the top of supporter; Annular upper oil cavitie 3 is set on contact-making surface on the supporter, the last oil duct 4 that is connected with upper oil cavitie is set on the supporter; Simultaneously annular lower oil cavitie 5 is set on the following contact-making surface of supporter, the following oil duct 6 that is connected with lower oil cavitie is set on the supporter.During use; Utilize oil outer pressing system input pressure oil in annular oil cavity, the contact-making surface of pressure stable oil between rotary body and supporter forms lubricating oil film, when playing " off-load " effect; Also reduced the frictional force between the two greatly; Rotation is easy, and has significantly reduced the lemel that hard friction brings, and has prolonged the service life of platen greatly.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
