When swinging certain angle, existing hydraulic cylinder cannot be met the requirements.
Summary of the invention
The purpose of this utility model is In view of the above shortcomings of the prior art, to provide a kind of pivot angle hydraulic cylinder, it has
There is swing angle controllable precise, easy to operate.
In order to achieve the above objectives, the pivot angle hydraulic cylinder of the utility model, including cylinder body, guide sleeve, cylinder bottom, piston rod, with
Piston, rod chamber hydraulic fluid port and the rodless cavity hydraulic fluid port of solid rod joint, guide sleeve is interior to be equipped with sealing element, it is characterised in that the piston
Bar is equipped with blind hole in one end of cylinder bottom, and piston is fixedly connected with the partition between piston rod and cylinder bottom, is equipped with side in partition
Hole；It is equipped in cylinder bottom with piston rod to perpendicular cavity, cavity is interior to be equipped with moveable rack gear, and the middle part of rack gear is equipped with
Several driving cogs, the both ends of rack gear are equipped with the sealing ring with cavity cooperation, and the cylinder bottom of rack gear two sides is equipped with hydraulic fluid port；In cylinder bottom
Interior equipped with the gear being meshed with driving cog, gear is connected firmly with drive rod, and drive rod is equipped with the side that cross section is matched with square hole
Axis, the square shaft pass through partition and are placed in the blind hole of piston rod.
The utility model is moved back and forth by two hydraulic fluid port oil inlets, promotion rack gear, by gear, drive rod band piston, piston
The forward and reverse swing of bar, the liquid volume of cavity is flowed by control, i.e., the swing angle of controllable piston rod has swing angle
Controllable precise, easy to operate advantage, and control device is set in cylinder bottom and cylinder body, small in size, practicability is good；
The gear two sides are equipped with shaft part as a further improvement of the utility model, between shaft part and cylinder bottom
Equipped with self-lubricating bushing；Gear can be accurately positioned, and rotated flexible；

Plug 5, rod chamber hydraulic fluid port 6 and rodless cavity hydraulic fluid port 7, guide sleeve 2 is interior to be equipped with sealing element 8, and the piston rod 4 is adjacent to one end of cylinder bottom 3
Interior to be equipped with blind hole 9, piston 5 is integrally fixedly connected with the partition 10 between piston rod 4 and cylinder bottom 3, is equipped with square hole (such as in partition 10
Square hole or hexagonal hole)；It is equipped in cylinder bottom 3 with piston rod to perpendicular cavity 11, cavity 11 is interior to be equipped with movably
Rack gear 12, the middle part of rack gear 12 are equipped with several driving cogs 13, and the both ends of rack gear 12 are equipped with annular groove, are equipped in annular groove and match with cavity
The cylinder bottom 3 of the sealing ring 14 of conjunction, 12 two sides of rack gear is equipped with hydraulic fluid port 15 or 16；It is equipped in cylinder bottom 3 and is meshed with driving cog 13
Gear 17, the welding of gear 17 and drive rod 18 connects firmly, and 17 two sides of gear are integrally installed with shaft part, shaft part and cylinder bottom 3 it
Between be equipped with self-lubricating bushing 20；Drive rod 18 is equipped with the square shaft 19 that cross section is matched with square hole, which passes through partition
10 are placed in the blind hole 9 of piston rod 4.
The utility model is moved back and forth by two hydraulic fluid ports 15 or 16 oil inlets, promotion rack gear 12, then by gear 17, drive rod
17, partition 10 flows into the liquid volume of cavity 11 by control with piston 5, the forward and reverse swing of piston rod 4, i.e., controllable to live
The swing angle of stopper rod 4 has the advantages that swing angle controllable precise, easy to operate；When rack gear 12 is moved to the limit at both ends
When position, piston rod 4 cannot have rotation relative to cylinder barrel, can only move along a straight line；
Control device is set in cylinder bottom 3 and cylinder body 1, and small in size, practicability is good；Self-lubricating bushing 20 can be accurate to gear 17
Positioning, and rotate flexible.
