Description
Technical Field
The utility model relates to a hydro-cylinder field specifically is a quick hydro-cylinder.
Background
The oil cylinder is a hydraulic actuating element which converts hydraulic energy of hydraulic oil into mechanical energy and makes linear reciprocating motion, oil is fed into the cylinder body to realize linear motion of the piston rod, the conventional oil cylinder works with the end face of the piston rod under the action of the hydraulic oil, the piston rod moving in such a way is usually slow in linear motion speed, and how to realize quick movement of the piston rod is a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to achieve a fast movement of the piston rod;
in order to solve the technical problem, the utility model provides a following technical scheme:
the utility model relates to a quick oil cylinder, which comprises a cylinder body and a second piston rod;
a first stroke groove is formed in the extending direction of the cylinder top of the cylinder body to the cylinder bottom of the cylinder body;
that is, one end of the cylinder body is an opening, and the first stroke groove is a cylindrical groove body.
A movable first piston rod is sleeved in the first stroke groove;
the first piston rod is sleeved in the first stroke groove and is cylindrical, and linear motion can be carried out along the first stroke groove.
A second stroke groove is formed in the end part, close to the cylinder bottom, of the first piston rod along the axis direction;
that is to say, the end face of the end part of the first piston rod extending into the first stroke groove is provided with a second stroke groove along the axis direction towards the end face of the other end part of the first piston rod, and the second stroke groove is a cylindrical groove body.
A second cylinder bottom is positioned in the cylinder body and fixedly arranged with the cylinder bottom;
one end of the second piston rod is fixed with the second cylinder bottom, and one end of the second piston rod is positioned in the second stroke groove;
an oil supply pipe is arranged at the end part of the second piston rod along the axial direction and close to the bottom of the second stroke groove;
the second cylinder bottom is used for fixing a second piston rod and is provided with an oil inlet connected with an oil supply pipe; an oil outlet of the oil supply pipe is positioned on the end face of the second piston rod and is close to the bottom of the second stroke groove;
an oil inlet is formed in the side wall of the bottom of the second cylinder and is connected with an oil supply pipe, and hydraulic oil enters the second stroke groove; the bottom of the second stroke groove is pushed by hydraulic oil, and the first piston rod moves linearly along the first stroke groove.
The utility model has the advantages that: the utility model relates to a quick hydro-cylinder, the second stroke inslot through the oil-out setting that will supply the oil pipe, because the area with the second stroke groove tank bottom of hydraulic oil contact is less than the terminal surface area of first piston rod, thereby the lifting surface area has been reduced, when the velocity of flow of hydraulic oil is unchangeable, increase pressure, second stroke groove tank bottom can receive bigger thrust, thereby make the quick motion of first piston rod in first stroke inslot, thereby realize the quick travel of piston rod.
