The cylinder head is welded with the cylinder barrel, the oil inlet of the rod cavity and the oil inlet of the rodless cavity are welded on the cylinder barrel, the oil inlet of the rodless cavity is welded on the cylinder head, and the oil inlet pipe of the rodless cavity connects the oil port of the rodless cavity and the oil inlet of the rodless cavity and is welded together in a sealing mode. The double-acting two-stage oil cylinder has reasonable design and novel structure, and can be used in machines with lifting action under various working conditions.
Description
Technical Field
The utility model relates to a two effect second grade hydro-cylinders.
Background
The existing double-acting single-stage oil cylinder has a rodless cavity oil inlet and a rod cavity oil inlet on a cylinder barrel. However, the oil inlet of the existing double-acting two-stage oil cylinder is generally an oil inlet without a rod cavity on the cylinder barrel, and an oil inlet with a rod cavity on the piston rod. When the rodless cavity is used for oil feeding, the oil pipe on the piston rod can be dragged together, when the rodless cavity is used for oil feeding, the oil pipe on the piston rod can also be dragged together, the normal use of related 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 double-acting two-stage oil cylinder is designed, and an oil inlet with a rod cavity and an oil inlet without a rod cavity are both arranged on a cylinder barrel of the oil cylinder.
The utility model provides a technical scheme that its technical problem adopted is:
the cylinder head 1 and the cylinder barrel 5 are welded together, the rod cavity oil inlet 8 and the rodless cavity oil inlet 7 are welded on the cylinder barrel 5, the rodless cavity oil port 2 is welded on the cylinder head 1, and the rodless cavity oil inlet pipe 6 connects and hermetically welds the rodless cavity oil port 2 and the rodless cavity oil inlet 7 together.
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 double-acting two-stage oil cylinder 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, the 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 the small piston 15 is propped against the supporting plate 3, the pressure oil starts to push the large piston 16 and drives the 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 a complete action of the double-acting secondary oil cylinder is completed. The double-acting two-stage oil cylinder has reasonable design and novel structure, and can be used in machines with reciprocating action under various working conditions.
