The two-stage oil cylinder with the supporting plate on the large piston has reasonable design and novel structure, and can be used for machines with lifting action under various working conditions.
Description
Technical Field
The utility model relates to a second grade hydro-cylinder that has the semi-circular arc groove on uide bushing.
Background
The size of the existing double-acting two-stage oil cylinder is not compact, the oil passage with the rod cavity can avoid the guide sleeve, and oil can be smoothly fed in the oil inlet without the rod cavity, but when the axial size is compact, the oil inlet with the rod cavity is not smooth, so that the requirement cannot be met.
Disclosure of Invention
The utility model aims at: a two-stage oil cylinder with a semi-circular arc groove on a guide sleeve 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:
four large semicircular grooves 91 are formed in the large guide sleeve 9, and four small semicircular grooves 101 are formed in the small guide sleeve 10.
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, and the service life of the oil pipe is prolonged.
The present invention will be described in detail with reference to the accompanying drawings.
Drawings
FIG. 1: a structure chart of a two-stage oil cylinder with a semi-arc groove on a guide sleeve.
FIG. 2 is a drawing: a structure diagram of a large guide sleeve of a secondary oil cylinder with a semicircular groove on the guide sleeve.
FIG. 3: a structure diagram of a small guide sleeve of a secondary oil cylinder with a semicircular groove on the guide sleeve.
In the drawings: 1-cylinder head, 2-rodless cavity oil port, 3-supporting plate, 4-sealing piece, 5-cylinder barrel, 6-rodless cavity oil inlet pipe, 7-rodless cavity oil inlet, 8-rod cavity oil inlet, 9-large guide sleeve, 10-small guide sleeve, 11-locking nut, 12-earring, 13-large piston rod, 14-small piston rod, 15-small piston, 16-large piston, 17-screw, 31-groove, 32-through hole, 91-large semicircular groove and 101-small semicircular groove.

The attached figure 1 in the specification shows: the large piston 16 is integrated with the large piston rod 13.
The attached figure 1 in the specification shows: the pallet 3 is connected to the large piston 16 using a plurality of screws 17.
The attached figure 2 in the specification shows: four large semicircular grooves 91 are arranged on the large guide sleeve 9
The attached figure 3 in the specification shows: the small guide sleeve 10 is provided with four small semicircular grooves 101.
A working process of a two-stage oil cylinder with a semicircular groove on a guide sleeve is as follows: 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 surface 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 surface of the supporting plate 3 props against the inner end surface of the cylinder head 1, the retraction of the oil cylinder is completed, and the complete action of the secondary oil cylinder with the semicircular arc groove on the guide sleeve is completed. The two-stage oil cylinder with the semi-circular arc groove on the guide sleeve has reasonable design and novel structure, and can be used in machines with reciprocating action under various working conditions.
