Abstract
The utility model relates to the servo-cylinder of the external displacement transducer of a kind of anti-rotation type.Its structure outline is also to comprise a kind of rotation-preventing mechanism, this rotation-preventing mechanism comprises guide rod and guide slide, guide rod is set in this guide slide, and guide rod one end is fixedly connected with piston rod, the medial axis of guide slide is parallel with cylinder body cylinder chamber, guide slide or be arranged on cylinder wall or be arranged on the discrete slipway affixed with cylinder body.This rotation-preventing mechanism is a kind of guiding device parallel with servo-cylinder piston movement direction, and guide rod moves in guide slide with the motion of piston, and the constraint by guiding device prevents that piston rod from rotating like this.Can effectively prevent that servo-cylinder piston from rotating in the course of the work, thus not reason piston rotation and affect the operating accuracy of displacement transducer.
Description
Technical field
The utility model relates to the servo-cylinder of the external displacement transducer of a kind of anti-rotation type.
Background technique
CN200920296036 has described a kind of technological scheme of external displacement transducer servo-cylinder, include cylinder barrel, front cover, rear end cover, piston rod, piston, external displacement transducer, mounting base, electric-hydraulic proportion conversion element, wherein cylinder barrel, front cover, rear end cover form the cylinder body with hollow cavity, in the hollow cavity of cylinder body, be equiped with piston rod and piston, piston rod connects external displacement transducer by link.Because piston rod adds rotation, do not constrain in cylinder body and can rotate freely, and the small accumulation rotatablely moving of piston rod may affect by link the precision of displacement transducer, even may cause that servo-cylinder lost efficacy.
Model utility content
The purpose of this utility model is to overcome deficiency of the prior art, and provide a kind of, prevents that piston rod from rotating to improve the servo-cylinder of the external displacement transducer of anti-rotation type of operating accuracy.
The servo-cylinder of the external displacement transducer of anti-rotation type, comprise cylinder body, piston rod, piston and displacement sensor component, displacement transducer is installed on cylinder body, sensor block is connected with piston rod, it forms main points and is, also comprise a kind of rotation-preventing mechanism, this rotation-preventing mechanism comprises guide rod and guide slide, guide rod is set in this guide slide, and guide rod one end is fixedly connected with piston rod, the medial axis of guide slide is parallel with cylinder body cylinder chamber, guide slide or be arranged on cylinder wall or be arranged on the discrete slipway affixed with cylinder body.
This rotation-preventing mechanism is a kind of guiding device parallel with servo-cylinder piston movement direction, and guide rod moves in guide slide with the motion of piston, and the constraint by guiding device prevents that piston rod from rotating like this.
The purpose of this utility model can also realize by following approach.
Also comprise a kind of link, sensor block and guide rod are all connected with piston rod by this link.
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 link.
In sum, the utility model compared to existing technology tool has the following advantages: can effectively prevent that servo-cylinder piston from rotating in the course of the work, thus not reason piston rotation and affect the operating accuracy of displacement transducer.
