Description

The oil hydraulic motor cylinder
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 the rotation and the reciprocal oil hydraulic motor cylinder of elastic feeding, energy complement and the automatic switchover of compound motion with two oil circuits.
Background technique
Present hydraulicdriven executive component mainly contains oil hydraulic motor and oil hydraulic cylinder two major types; Under hydraulic pressure, realize positive and negative rotatablely moving or linear reciprocating motion respectively; But the complex form that in plurality of applications, needs above-mentioned two kinds of motions, the rotation of promptly automaticallying switch is with reciprocal.Present rotating hydraulic cylinder or oscillating oil cylinder all can only be realized piston shaft or the rotation of cylinder body in certain angle range under the hydraulic pressure, are used for the rotation positioning function more, and the reciprocal compound motion of rotation that can not realize having certain load capacity.And in actual use, have the realization of the reciprocal compound motion of rotation of load capacity, and all need separate driving mechanism combination to use, system architecture is complicated, and volume is numerous and jumbled.
Summary of the invention
Technical problem to be solved by this invention is to above-mentioned existing technology and propose the reciprocal oil hydraulic motor cylinder of a kind of rotation simple in structure, and it only just realizes rotation and reciprocal elastic feeding, automatic switchover with two oil circuits in single cylinder body.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: the oil 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; The internal surface that it is characterized in that described stator outer rim and cylinder body closely cooperates; Described stator, oil distribution casing, auxiliary axis contiguous block and auxiliary axis connect into an integral body through locating stud and form stator modules, and inboard wall of cylinder block is provided with limit commentaries on classics slideway and matches with stator modules, rotates with the restriction stator modules; Described rotor is fixedly connected as a whole with working shaft, the two ends of its joint link into an integrated entity through pair of planar thrust-bearing and locking nut and stator modules simultaneously.
Press such scheme, described working shaft and auxiliary axis reach the two ends of cylinder body outward respectively and match with cylinder body both sides end cap.
Press such scheme, also be connected with of the rotation of auxiliary axis rotating limit block on the described auxiliary axis, the moment of reaction that produces when overcoming the working shaft rotation with the restriction stator modules.
Hydraulic oil of the present invention is through 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 gets into the enclosed space that stator, rotor surrounded through the perforate on the oil distribution casing, promotes rotor banding and starts building to do axis rotation.Because the rotation of working shaft and to-and-fro motion be based on same hydraulic power, to load when excessive when the rotation torque of working shaft, hydraulic coupling can be regulated the promotion piston automatically and moved reciprocatingly; When thrust was 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 then change, changes motionless and then push away " in brief, so, in single cylinder body, only just can realize rotating with two oil circuits and the elastic feeding and the energy complement of reciprocal compound motion.
Beneficial effect of the present invention is: the characteristics of conventional hydraulic motors and two kinds of executive components of oil hydraulic cylinder are combined; Not only accomplished the function of piston but also accomplished the function of motor with a kind of new parts, just realized rotation and the back and forth elastic feeding and the automatic switchover of compound motion with two oil circuits at single cylinder body.The present invention is simple in structure, and is easy to operate, can be widely applied to engineering fields such as machine tool motion control, excavation work, stirring engineering, field drilling exploitation.
Description of drawings
Fig. 1 is a front section view of the present invention;
Among the figure, 1-working shaft, 2, the 11-oil inlet and outlet, 3, the 8-thrust-bearing, 4, the 7-oil distribution casing; The 5-rotor, 6-stator, 9-auxiliary axis contiguous block, 10-locating stud; 12-auxiliary axis rotating limit block, 13-auxiliary axis, 14-rear end cover, 15-locking nut; The 16-abutment sleeve, the 17-limit is changeed slideway, 18-cylinder body, 19-working shaft end cap.
Embodiment
Through embodiment the present invention is done further detailed explanation below in conjunction with accompanying drawing, but this explanation can not be construed as limiting the invention.
As shown in Figure 1; The oil hydraulic motor cylinder includes cylinder body 18, working shaft 1 and auxiliary axis 13, and the both sides of cylinder body 18 are respectively arranged with rear end cover 14 and working shaft end cap 19; Described working shaft 1 reaches the two ends of cylinder body 18 outward respectively with auxiliary axis 13 and matches with cylinder body both sides end cap; Said cylinder interior is provided with stator 6, rotor 5 and a pair of oil distribution casing (4,7), and a pair of oil distribution casing (4,7) is symmetricly set in the two ends of stator 6 and rotor 5, and the internal surface of stator 6 outer rims and cylinder body 18 is closely cooperated; To replace piston; Described stator 6, oil distribution casing (4,7), auxiliary axis contiguous block 9 and auxiliary axis 13 connect into an integral body through locating stud 10 and form stator modules, and cylinder body 18 inwalls are provided with limit to be changeed slideway 17 and match with stator modules, with the rotation of restriction stator modules; The spline of rotor 5 is connected working shaft 1, and the two ends of its joint are provided with plain thrust bearing (3,8) and are connected with stator modules with abutment sleeve 16, locking nut 15; The cylinder body both sides are provided with into and out of hydraulic fluid port 2 and 11.After pressure oil got into active chamber through an end hydraulic fluid port, total discharge Q was divided into two, flow Q 1Act on the piston area that the end face of oil-feed side oil distribution casing forms, make piston make ahead running; Flow Q 2By the enclosed space that the entering of the perforate on oil distribution casing stator 6, rotor 5 are surrounded, promote rotor 5 drive working shafts 1 and rotate; Through the handover operation of two ends hydraulic fluid port, the reciprocating direction of may command piston.Just realize rotation and reciprocal elastic feeding, the compound motion of automatic switchover at single cylinder body with two oil circuits.
