Description
Technical Field
The utility model relates to a have second grade hydro-cylinder of end cap on big piston.
Background
The existing double-acting two-stage oil cylinder has a rod cavity oil inlet pipe which is generally arranged on the inner part of a small piston rod, when a rodless cavity is used for oil inlet, an oil pipe on the piston rod can be dragged together, when the rod cavity is used for oil inlet, the oil pipe on the piston rod can also be dragged together, the normal use of other objects can be influenced frequently during dragging, and the oil pipe is easy to fatigue damage due to long-term stretching and bending. Therefore, users demand that the oil pipe of the double-acting two-stage oil cylinder does not move along with the piston when the oil cylinder works, and the requirements cannot be met. *+
Disclosure of Invention
The utility model aims at: a two-stage oil cylinder with a plug on a large piston is designed, and an oil inlet with a rod cavity and an oil inlet without a rod cavity are all arranged on a cylinder barrel of the oil cylinder.
The utility model provides a technical scheme that its technical problem adopted is:
the large piston 16 and the large piston rod 13 are integrated, the oil inlet channel 133 is communicated with the oil inlet 132, the end face of the oil inlet channel 133, which is close to the large piston 16, is welded with the plug 4, and the oil inlet channel 133 is communicated with the half edge of the positioning hole 131 of the guide sleeve.
The beneficial effects of the utility model are that, there is the pole chamber to advance the pipe and do not interfere other articles, occupation space is few. The oil pipe can not be damaged by fatigue
The present invention will be described in detail with reference to the accompanying drawings.

A working process of a two-stage oil cylinder with a large piston and a plug comprises the following steps: when the piston rod extends out, pressure oil enters from an oil inlet 7 of the rodless cavity, enters along an oil inlet pipe 6 of the rodless cavity, an oil port 2 of the rodless cavity and an oil passage of the cylinder head 1, and pushes a large piston 16 to extend outwards along a large guide sleeve 9 until the step of the large piston 16 is propped against the large guide sleeve 9, so that hydraulic oil continues to enter along the oil hole of the supporting plate 3, a small piston 15 is pushed, a small piston rod 14 moves outwards along a small guide sleeve 10 and extends out completely, and piston rods of the two-stage oil cylinder extend out completely; when pressure oil enters an oil inlet 8 of the rod cavity, an extended small piston rod 14 starts to retract under the restraint of the small guide sleeve 10 under the action of the pressure oil, when the end face of a small piston 15 is propped against the supporting plate 3, the pressure oil starts to push a large piston 16 and drives a large piston rod 13 to retract under the restraint of the large guide sleeve 9 until the end face of the supporting plate 3 props against the inner end face of the cylinder head 1, the retraction of the oil cylinder is completed, and the complete action of the secondary oil cylinder with the plug on the large piston is completed. The two-stage oil cylinder with a large piston and a plug is reasonable in design and novel in structure, and can be used in machines with reciprocating action under various working conditions.
