The hydraulic motor cylinder has the beneficial effects that the characteristics of the traditional two actuation elements such as a hydraulic motor and a hydraulic cylinder are combined together, the functions of the piston and the motor are completed by a new part, and elastic feeding and automatic switching in the composite motion of rotation and reciprocation are realized by using two oil paths on single cylinder body. The structure is simple, and the operation is convenient.
Description
Technical field
The present invention relates to a kind of new hydraulic actuator, concrete relating to a kind ofly can be in single cylinder body be only realized rotation and the reciprocal hydraulic motor cylinder of elastic feeding, energy complement and the automatic switchover of compound motion with two oil circuits.
Background technique
Current hydraulicdriven executive component mainly contains oil hydraulic motor and the large type of oil hydraulic cylinder two, under hydraulic pressure, realize respectively positive and negative rotation motion or linear reciprocating motion, but the complex form that needs above-mentioned two kinds of motions in much applying, the rotation of automatically switching is with reciprocal.Current rotating hydraulic cylinder or oscillating oil cylinder, all can only realize piston shaft in the certain angle range under hydraulic pressure or the rotation of cylinder body, is used for rotating locating function, and can not realizes the reciprocal compound motion of rotation with certain load capacity.And in actual use, there is the realization of the reciprocal compound motion of rotation of load capacity, and all need separate driving mechanism to be used in combination, system architecture is complicated, and volume is numerous and jumbled.
Summary of the invention
Technical problem to be solved by this invention is to propose the reciprocal hydraulic motor cylinder of a kind of rotation simple in structure for above-mentioned prior art, and it only just realizes rotation and reciprocating elastic feeding with two oil circuits in single cylinder body, automatically switches.
The present invention solves the problems of the technologies described above adopted technological scheme: hydraulic motor cylinder, include cylinder body, working shaft and auxiliary axis, described cylinder interior is provided with stator, rotor, oil distribution casing, auxiliary axis contiguous block and locating stud, it is characterized in that described stator outer rim and the internal surface of cylinder body closely cooperate, described stator, oil distribution casing, auxiliary axis contiguous block and auxiliary axis connect into an integral body by locating stud and form stator modules, the limited slideway that turns is set on inboard wall of cylinder block to match with stator modules, with restriction stator modules, rotate, described rotor is fixedly connected with as a whole with working shaft, the two ends of its joint link into an integrated entity by pair of planar thrust-bearing and locking nut and stator modules simultaneously.
Press such scheme, described working shaft and auxiliary axis are extended to respectively the two ends of cylinder body and match with cylinder body both sides end cap.
Press such scheme, on described auxiliary axis, be also connected with auxiliary axis rotating limit block with the rotation of restriction stator modules, the moment of reaction producing while overcoming working shaft rotation.
Hydraulic oil of the present invention is by oil inlet and outlet, and a part of flow acts on the formed piston area of oil distribution casing end face, makes piston reciprocates; Another part flow enters by the perforate on oil distribution casing the enclosed space that stator, rotor surround, and drive rotor drives working shaft to rotate.Because the rotation of working shaft and to-and-fro motion are based on same hydraulic power, when the rotation torque of working shaft is loaded when excessive, hydraulic coupling can automatically regulate and promote piston and move reciprocatingly; When thrust is excessive with respect to moment of torsion, it is leading that the rotatablely moving of working shaft just accounts for, and is " push away motionless turn, turn motionless and push away " in brief, so, in single cylinder body, only with two oil circuits, just can realize and rotating and elastic feeding and the energy complement of reciprocal compound motion.
Beneficial effect of the present invention is: the feature of conventional hydraulic motors and two kinds of executive components of oil hydraulic cylinder is combined, with a kind of new parts, not only completed the function of piston but also completed the function of motor, for single cylinder body, two oil circuits are just realized rotation and back and forth elastic feeding and the automatic switchover of compound motion.The present invention is simple in structure, easy to operate, can be widely applied to the engineering fields such as machine tool motion control, excavation work, stirring engineering, field drilling exploitation.
