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

The servo-cylinder of the external displacement transducer of anti-rotation type

Technical field

The present invention 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.

Summary of the invention

The object of the invention is to overcome deficiency of the prior art, and provide a kind of, prevent 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.

Object of the present invention 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 present invention 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.
