Description
Technical field
The utility model relates to a kind of hydraulic control, belongs to mechanical-hydraulic compound gearing, is mainly used in the control of three stations in mechanical transmission or location.
Background technique
In various hydraulic actuator, two work position hydraulic cylinders are the most frequently used mechanisms, when running into the transmission campaign of needs three station or location, are adopt mechanical structure to realize substantially.
Summary of the invention
For better realizing the control of three stations in mechanical transmission or location, the utility model provides a kind of three station single-action hydraulic cylinders, and the control accurate positioning of this oil hydraulic cylinder is reliable, by hydraulic pressure program control without the need to manual operation.
The technical solution of the utility model is: for three station single-action hydraulic cylinders of mechanical transmission or positioning control, comprise seal ring, screw, piston shaft, end cap, piston sleeve, pipe joint, cylinder body.Described hydraulic cylinder body diameter of bore one end is little, one end is large, described piston shaft base section alive coordinates with cylinder body small diameter inner hole part, described piston sleeve is assemblied in the larger diameter internal bore of cylinder body, the endoporus of piston sleeve matches with the axle journal of piston shaft, end cap has two both sides being arranged in cylinder body respectively, described piston shaft stretches out from the endoporus of the end cap of one end, described pipe joint is arranged on cylinder body excircle, inner chamber is formed at cylinder interior end cap and piston sleeve, piston sleeve and piston shaft intermediate piston part form inner chamber, described piston shaft and piston sleeve endoporus, end cap endoporus is provided with seal ring, piston sleeve cylindrical, end cap and cylinder inner bore are provided with seal ring leakage proof.Described piston sleeve to be held in respective inner chamber and axial motion can be positioned at the endface position of lumen pore about piston shaft.
During application, hydraulic oil enters oil hydraulic cylinder lumen pore by pipe joint, the change of inner chamber of cylinder block diameter forms thrust variation, the change control piston cover connected by hydraulic oil in three pipe joints and piston shaft location, piston shaft can realize the change of three positions, and the piston shaft single-acting end cylinder synchronous in vitro that overhangs out realizes the change of three stations.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model three station single-action hydraulic cylinder structural representation.
Embodiment
See accompanying drawing, the utility model provides a kind of three station single-action hydraulic cylinders, comprises seal ring 1, screw 2, seal ring 3, seal ring 4 seal ring 5, seal ring 6, seal ring 7, screw 8, piston shaft 9, end cap 10, pipe joint 11, piston sleeve 12, pipe joint 13, cylinder body 14, pipe joint 15, end cap 16.
Cylinder body 14 diameter of bore one end of described three station single-action hydraulic cylinders is little, one end is large, and piston shaft 9 one end coordinates with cylinder body 14 small diameter portion, piston shaft 9 output terminal and piston sleeve 12, end cap 10 inner hole overhanging out outside cylinder body.
The end cap 10 of described three station single-action hydraulic cylinders is assemblied in cylinder body 14 port by screw 2, and piston shaft 9 stretches out from end cap 10 endoporus, and described end cap 16 is fixed on cylinder body 14 the other end by screw 8.
The pipe joint 11 of described three station single-action hydraulic cylinders, pipe joint 13, pipe joint 15 totally three be arranged on cylinder body 14 excircle, form inner chamber at cylinder body 14 inner end cap 10 and piston sleeve 12, end cap 16 forms inner chamber with piston shaft 9, piston sleeve 12 and piston shaft 9 piston portion form inner chamber, three pipe joints respectively with three intracavity inter-connections, described piston shaft 9 is provided with seal ring with piston sleeve 12, end cap 10 endoporus, and piston sleeve 12 cylindrical, end cap 10, end cap 16 are provided with seal ring leakage proof with cylinder body 14 endoporus.
The piston shaft 9 of described three station single-action hydraulic cylinders is spacing in cylinder body 14 in the inner chamber separately of two ends, left and right according to end face, and piston shaft 9 axial motion is also positioned at the endface position of lumen pore.
The piston shaft 9 of described three station single-action hydraulic cylinders stops the intracavity diameter change formation thrust variation that principle applies cylinder body 14, and when pressurizeing in pipe joint 13, piston shaft 9 is pushed into end cap 16 place on the right side of cylinder body 14; When pressurizeing in pipe joint 11, pipe joint 15 simultaneously, piston shaft 9 is pushed into cylinder body 14 middle endoporus step place; When pressurizeing in pipe joint 15, piston shaft 9 drives piston sleeve 12 to push cylinder body 14 and end cap 10 end contact place to.
