Description
Technical field
The utility model is related to a kind of swing mechanism, particularly it is electro-hydraulic driving integrated with mechanical swing mechanism together with set
It is standby.
Background technology
Existing swing mechanism mainly passes through the rotating of crank and rocker mechanism, surface of revolution cam mechanism, control input axis
Or the several method such as gear mechanism is swung clockwise and anticlockwise to realize.Realized using crank and rocker mechanism by rotation motion
For swing when, when rotary motion be uniform rotation, swing speed is non-uniform, and swing both direction on movement when
Between it is different；Realized using the surface of revolution cam mechanism when being changed into swinging by rotation, when the groove on the surface of revolution is difficult to ensure that swing
Speed is uniformly and hardly possible is processed；Swing is realized by the way of control input axis rotating, it is higher to control section requirement, and
The swing speed of usual output shaft relatively difficult to achieve is stablized constant；Combined mechanism during using gear mechanism mode to realize swing
It is more complicated, and safeguard that relative difficulty noise is big.
Present swing mechanism is typically all to be directly driven by a motor, so that the torque of driving is smaller and what is produced makes an uproar
Sound is larger, it is impossible to the problems such as larger torque is realized in realization in less space.When using motor driving when, if by two or
Two or more swing mechanism will be to motor with counter electromotive force, so as to electricity occur in moment when connecting and having a phase difference requirement
The situation that the positive antipole in source is connected, this is difficult to be avoided.
The content of the invention
There is the electricity that response is fast, precision is high, simple in structure, driving torque is big the purpose of this utility model is to provide a kind of
Liquid drives swing mechanism.The utility model is mainly used in the high-grade, precision and advanced particular field for having rigorous to swing angle and speed etc.
Close, pumped by servomotor and two-way quantitative, precision control hydraulic cylinder realizes the swing of mechanical structure.Two accumulators, which are realized, to be mended
Oil is adapted to increasingly complex operating mode with providing extra power.
The utility model mainly includes：Servomotor, hydraulic pump, hydraulic oil accumulator, repairing accumulator, hydraulic cylinder, pressure
Force snesor, displacement sensor, safety valve, check valve and hydraulic cylinder are with swinging shaft connection mechanism.Wherein, servomotor and hydraulic pressure
Pump is connected, which pumps for two-way quantitative, and two outlets exported respectively with a check valve of two-way quantitative pump are connected, and two
The import of a check valve is connected with repairing accumulator, and repairing accumulator is used for equivalent to the slippage pump in conventional closed system
Fluid is supplemented into system.Preferably, a hydraulic oil is respectively set on two pipelines that two check valves are connected with two-way quantitative pump
Accumulator.Preferably, it is also in parallel with two safety valves respectively to pump two actuator ports for two-way quantitative.The two-way quantitative pump leads to respectively
Cross and set the pipeline of pressure sensor and be connected with hydraulic cylinder both ends oilhole.The hydraulic cylinder for it is double go out rod structure, piston rod fixes, cylinder barrel
Movement, displacement sensor are oil cylinder built-in type displacement sensor, and magnet ring is installed on piston section with non-magnetic gasket.In hydraulic pressure
Cylinder is equipped with its bindiny mechanism with swinging axle, i.e. Barrel of Hydraulic Cylinders passes through the connector rolling vertical with cylinder barrel with an axis
Bearing inner race is connected, which is placed in the sliding slot of rocking bar, and the other end of rocking bar is connected with swinging axle, the length of rocking bar
Degree is determined according to swinging axle rotational angle.Fixed for Shaft angle will be swung, the restriction bearing stroke preferably in rocking bar sliding slot
Position-limit mechanism.
The course of work of the utility model approximately as：Servomotor drives hydraulic pump, and controllable its turns to and rotating speed,
Repairing accumulator and two check valves, which coordinate, to carry out repairing to system.Hydraulic cylinder under the effect of hydraulic oil that hydraulic pump exports into
Row movement, and drive coupled rolling bearing to be slided in the sliding slot of rocking bar, and then drive the oscillating rod being connected with rocking bar
Rotate.Pressure sensor can carry out the monitoring of fundamental physical quantity in real time with displacement sensor, and the signal of collection is fed back to and is watched
Amplidyne generator, the uninterrupted of control hydraulic pump output and direction are taken, and then controls movement and the position of hydraulic cylinder, to realize
Position and the closed-loop control of power.Other two hydraulic oil accumulators of the utility model can provide moment pulsation for movement cylinders body,
Quick movement, steady operation pressure are realized under special operation condition.In addition safety valve can prevent shock loading from causing to damage to system.
The utility model has the following advantages that compared with prior art：
(1) driven using servo electrohydraulic, response is fast, swing angle control accuracy is high, simple in structure, driving torque is big.
(2) driven using servo electrohydraulic, avoid motor when directly being driven using motor and having phase difference requirement and add
Counter electromotive force.
(3) driven using servo electrohydraulic, type of drive is simple, easy to maintain, noise is small.
(4) overflow valve, individual event valve are inserted on integrated valve block, some high-grade, precision and advanced special occasions can be met to small
It is required that.
