Abstract
The invention discloses a cylinder structure with a function of regulating the reciprocating speed of a piston rod by the aid of the quantity of inlet and outlet ports. The cylinder structure comprises a cylinder barrel. A front end cover and a rear end cover are respectively fixed to the front end and the rear end of the cylinder barrel, the piston rod which is matched with the cylinder barrel extends out of a center hole of the front end cover, and sealing rings are respectively arranged between the front end cover and the cylinder barrel, between the rear end cover and the cylinder barrel and between the front end cover and the piston rod. The cylinder structure is characterized in that a first oil inlet and outlet port and a fourth oil inlet and outlet port are formed in the front end cover, a second oil inlet and outlet port and a third oil inlet and outlet port are formed in the rear end cover, and connectors or screwed plugs are connected with the various oil inlet and outlet ports in a threaded manner. The cylinder structure has the advantages that the quantity of the oil inlet and outlet ports is determined as needed when the cylinder structure is mounted, in other words, a single-inlet and single-outlet mode or a double-inlet and double-outlet mode or a single-inlet and double-outlet mode or a double-inlet and single-outlet mode can be selected, accordingly, the piston rod can implement various reciprocating actions such as slow advancing and slow withdrawing actions or fast advancing and fast withdrawing actions or slow advancing and fast withdrawing actions or fast advancing and slow withdrawing actions, and the oil inlet and outlet ports can be blocked by the screwed plugs when neither modes is selected; the integral cylinder structure is simple and is convenient to adjust, and the manufacturing cost can be greatly reduced.
Description
Technical field
The present invention relates to a kind of cylinder structure, particularly a kind of cylinder structure of importing and exporting quantity regulating piston rod shuttle speed that utilizes.
Background technique
Cylinder structure comprises cylinder barrel, the two ends of cylinder barrel are fixedly connected with respectively end cap, stretch out and join dependency parts with piston rod one end to the end cap central bore that oil cylinder matches, on the end cap at two ends, be all processed with an oil inlet and outlet, the oil inlet and outlet pipe joint that has been threaded, joins by pipe joint and hydraulic control device.The cold reciprocating speed of bar of living generally regulates by valve group, complex structure, and cost is high.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, low cost of manufacture, the cylinder structure of quantity regulating piston rod shuttle speed is imported and exported in utilization easy to adjust, overcomes the deficiencies in the prior art.
The cylinder structure of quantity regulating piston rod shuttle speed is imported and exported in utilization of the present invention, comprise cylinder barrel, front-end and back-end at cylinder barrel are fixed with respectively front cover and rear end cover, the piston rod matching with cylinder barrel stretches out from the center hole of front cover, between front cover and rear end cover and cylinder barrel, be equipped with seal ring between front cover and piston rod; It is characterized in that: described front cover is provided with the first oil inlet and outlet and the 4th oil inlet and outlet, rear end cover is provided with the second oil inlet and outlet and the 3rd oil inlet and outlet, each oil inlet and outlet be threaded connecting head or plug.
The cylinder structure of quantity regulating piston rod shuttle speed is imported and exported in utilization of the present invention, because there are respectively two oil inlet and outlets at cylinder barrel two ends, during installation, determine as required the quantity of oil inlet and outlet, i.e. choosing singly enters singly go out or go with each other all the time or Dan Jinshuan goes out or twoly enters singly to go out, can realize the multiple reciprocating action that slow-motion is returned slowly or F.F. returns to or slow-motion returns to or F.F. is returned slowly of piston rod, not select oil inlet and outlet can utilize plug shutoff.Overall structure is simple, greatly reduces manufacture cost, easy to adjust.
Accompanying drawing explanation
