Abstract
The invention relates to an anti-rotation servo oil cylinder of an external displacement sensor. The servo oil cylinder is structurally characterized in that an anti-rotation mechanism is further included, the anti-rotation mechanism comprises a guide rod and a guide slide way, the guide rod penetrates through the guide slide way in a sleeved mode, one end of the guide rod is fixedly connected with a piston rod, the medial axis of the guide slide way is parallel to a cylinder cavity, and the guide slide way is arranged on a cylinder wall or on a split slide way body fixedly connected with a cylinder body. The anti-rotation mechanism is a guide device parallel to the moving direction of a piston of the servo oil cylinder, the guide rod moves in the guide slide way along with moving of the piston, and accordingly the piston rod is prevented from rotating through limiting of the guide device. The piston of the servo oil cylinder can be effectively prevented from rotating in work, and accordingly the situation that work precision of a displacement sensor is influenced due to rotation of the piston does not occur.
Description
Technical field
The present invention relates to a kind of servo-cylinder of the outer displacement sensor of anti-rotation type.
Background technology
CN200920296036 describes a kind of technical scheme of external displacement transducer servo-cylinder, includes cylinder
Cylinder, drive end bearing bracket, rear end cap, piston rod, piston, external displacement transducer, mounting seat, electric-hydraulic proportion conversion element, wherein
Cylinder barrel, drive end bearing bracket, rear end cap composition have the cylinder body of hollow cavity, are equiped with piston rod and piston in the hollow cavity of cylinder body,
Piston rod connects external displacement transducer by connector.Do not put english to turn due to piston rod and constrain in cylinder body and can freely revolve
Turn, and the accumulation of the small rotary motion of piston rod may affect the precision of displacement transducer in some instances it may even be possible to draw by connector
Play servo-cylinder to lose efficacy.
Content of the invention
It is an object of the invention to overcoming weak point of the prior art, and one kind is provided to prevent piston rod from rotating to carry
The servo-cylinder of the outer displacement sensor of the anti-rotation type of high workload precision.
The servo-cylinder of the outer displacement sensor of anti-rotation type, including cylinder body, piston rod, piston and displacement sensor component,
Displacement transducer is installed on cylinder body, and sensor block is then connected with piston rod, and its composition is characterized by, and also includes a kind of anti-favourable turn
Structure, this rotation-preventing mechanism includes guide post and guide slide, and guide post wears in this guide slide, and guide post one end and piston
Bar is fixedly connected, and the axis of guide slide is parallel with cylinder body barrel chamber, guide slide or be arranged on cylinder wall or arrange
On the discrete slipway affixed with cylinder body.
This rotation-preventing mechanism is a kind of guider parallel with servo-cylinder piston movement direction, and guide post is with the fortune of piston
Move and move in guide slide, so piston rod rotation is prevented by the constraint of guider.
The purpose of the present invention can also be realized by following approach.
Also include a kind of connector, sensor block and guide post are all connected with piston rod by this connector.
Displacement transducer is magnetic induction displacement transducer or grating displacement sensor.
Sensor block is arranged on sensor block support, and sensor block support is fixedly connected with connector.
In sum, the present invention has the advantage that compared to existing technology:Servo-cylinder piston can effectively be prevented in work
During rotate, thus not reason piston rotate and affect the operating accuracy of displacement transducer.

Specific embodiment
Most preferred embodiment
As depicted in figs. 1 and 2, the servo-cylinder of the outer displacement sensor of anti-rotation type, including forward and backward end cap 1,5, cylinder body 2,
Piston rod 4, piston 3, displacement sensor component 7 and a kind of rotation-preventing mechanism 6, displacement transducer 73 is installed on cylinder body 2, sensor block
71 are then connected with piston rod 4 by sensor block support 72 and connector 63, and this rotation-preventing mechanism includes guide post 61 and guiding is slided
Road, guide post 61 wears in this guide slide, and guide post 61 one end is fixedly connected with piston rod 4 by connector 63, leads
Parallel with cylinder body barrel chamber to the axis of slideway, guide slide is arranged on the discrete slipway 62 affixed with cylinder body.This anti-rotation
Mechanism is a kind of guider parallel with servo-cylinder piston movement direction, guide post with piston motion and in guide slide
Middle movement, so prevents piston rod rotation by the constraint of guider.Displacement transducer is magnetic induction displacement transducer or light
Displacement transducer.
The present invention is not described partly same as the prior art.
