Abstract
The utility model belongs to mechanical manufacturing field more particularly to a kind of single-acting hydrostatic support actuator, including piston rod（1）, drive end bearing bracket（2）, flow controller（3）, cylinder barrel（4）, rear end cap（5）, the drive end bearing bracket（2）And rear end cap（5）It is installed in cylinder barrel location hole, piston rod（1）From drive end bearing bracket（2）It is pierced by, two oil discharge outlets is opened up on the drive end bearing bracket（6）, flow controller is installed in hydraulic fluid port（3）, flow controller（3）Oil outlet end offers oil pocket（7）.Hydrostatic support was separately positioned on the mounting means in drive end bearing bracket and rear end cap by the utility model change in the past, and two-way hydraulic fluid port is installed concentratedly on drive end bearing bracket, the suspension of piston rod is just realized only by drive end bearing bracket, effectively reduces installation difficulty.
Description
Technical field
The utility model belongs to mechanical manufacturing field, especially a kind of single-acting hydrostatic support actuator.
Background technology
Hydrostatic support cylinder is the height for being applied to the fields such as material, part, equipment fatigue test, vibration test, impact test
Frequency, the high performance servo actuator of high-speed.It is floated plug screw bar by the effect of two radial thrust bearings of hydrostatic support
It is dynamic to be supported among end cap, make it contactless between end cap, cylinder barrel, realize zero friction, the characteristics of high frequency sound.
The hydrostatic support actuator applied on the market at present is all that double acting structure is divided into forward and backward end cap, cylinder barrel, piston rod
Etc. several majors, hydrostatic support be separately positioned on drive end bearing bracket and rear end cap, but since its requirement to machining accuracy is very high,
Can all hydrostatic support be caused to fail once minimum deviation occurs in front and rear cover concentric locating, therefore this mode technical difficulty
Height, processing cost remain high.
The content of the invention
To overcome above-mentioned technological deficiency, the utility model discloses a kind of single-acting hydrostatic support actuator, the technology taken
Scheme is that a kind of single-acting hydrostatic support actuator is described including piston rod, drive end bearing bracket, flow controller, cylinder barrel, rear end cap as schemed
Drive end bearing bracket and rear end cap are installed in cylinder barrel location hole, and piston rod is pierced by from drive end bearing bracket, and two oil discharge outlets are opened up on the drive end bearing bracket,
Flow controller is installed, flow controller oil outlet end offers oil pocket in hydraulic fluid port.
The advantageous effect that the present invention obtains is that tandem arranges two rows of hydrostatic support oil pockets on the end cap, is formed
Two radial thrust bearings.Fuel feeding is carried out to two radial bearings by the oil circuit hole on end cap.It is achieved thereby that only pass through
Drive end bearing bracket can float piston rod.It changes existing way and hydrostatic support is all set in drive end bearing bracket and rear end cap, make rear end
Lid only plays the effects that sealing, installation, effectively reduces assembly difficulty.
Description of the drawings
Fig. 1 is the utility model section view.
Specific embodiment
As shown in Figure 1, a kind of single-acting hydrostatic support actuator of the utility model, including piston rod 1, drive end bearing bracket 2, section
Device 3, cylinder barrel 4, rear end cap 5 are flowed, the drive end bearing bracket 2 and rear end cap 5 are installed in cylinder barrel location hole, and piston rod 1 is worn from drive end bearing bracket 2
Go out, two oil discharge outlets 6 are opened up on the drive end bearing bracket, flow controller 3 is installed in hydraulic fluid port 6,3 oil outlet end of flow controller offers oil pocket 7.
