Description
Technical Field
The utility model relates to a second grade hydro-cylinder that has the layer board on the big piston.
Background
After the small piston of the existing double-acting two-stage oil cylinder retracts to the bottom, axial positioning is generally realized by relying on a clamp spring positioned in a large piston hole, and the clamp spring is often loosened in the positioning mode, so that equipment faults such as scrapping of the oil cylinder are caused.
Disclosure of Invention
The utility model aims at: a two-stage oil cylinder with a large piston and a supporting plate is designed, so that the oil cylinder does not break down in the use process
The utility model provides a technical scheme that its technical problem adopted is:
the end face of the large piston 16 is connected with a supporting plate 3, and the supporting plate 3 is provided with a groove 31 and a through hole 32.
The beneficial effects of the utility model are that, the layer board can not drop, and occupation space is few, can not arouse the trouble.
The present invention will be described in detail with reference to the accompanying drawings.

A working process of a secondary oil cylinder with a large piston and a supporting plate 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 supporting plate on the large piston is completed. The two-stage oil cylinder with the supporting plate on the large piston has reasonable design and novel structure, and can be used in machines with reciprocating action under various working conditions.
