Abstract
The utility model discloses a precise electronic plug guage which comprises a base, a sensor, an elastomer, a measurement anvil, a measurement claw and a measurement tip. The sensor is a standard displacement sensor comprising an inductive choke and a magnetic core; the measurement tip is connected with the measurement claw through a thread; the measurement claw is fixed on the elastomer through a bolt; the contact of the sensor clings to the measurement anvil through a pull spring. The precise electronic plug guage is characterized in that the inductive choke and the magnetic core are separately sealed in the sensor, the inductive choke, an insulating sleeve and the sensor shell are fixedly connected into a whole, and the magnetic core, a connecting shaft and the sensor contact are fixedly connected into a whole. As the sensor has good sealing property, the change of the inductance during the use does not lead to the change of the current so the size measurement is stable.
Description
Technical field
The utility model relates to PRECISION HOLE electron detection device field, particularly a kind of precise electronic feeler gauge.
Background technology
Electronic plug gauge is a kind of checkout equipment of mechanical field, is usually used in measuring the size in aperture etc.The present electronic plug gauge that uses, its structure is that telefault is directly installed on the elastomeric test arm, when being used for online detection, because of there being grinding fluid in the measured hole, grinding fluid flows in the telefault by gauge head, measuring jaw, elastic body easily in detection, cause variation inductance, and the value of detection is drifted about, the testing result instability.
The utility model content
The utility model provides a kind of precise electronic feeler gauge for addressing the above problem, and can obtain stable and more accurate testing result.
The technical solution of the utility model is as follows:
A kind of precise electronic feeler gauge, comprise bearing, sensor, elastic body, gage button, measuring jaw and gauge head, described sensor is the normal bit displacement sensor that includes telefault and magnetic core, described gauge head is by being threaded with measuring jaw, measuring jaw by screw retention on elastic body, the contact of described sensor is close on the gage button by extension spring, it is characterized in that: described telefault and magnetic core are sealed in the sensor separately, described telefault, insulation sleeve are fixedlyed connected with sensor outer housing and are integral, and described magnetic core, coupling shaft and sensor contact are fixedly connected to form one.
The shell of described sensor is fixed on an elastomeric side by lock-screw.
Be integral by the viscose glue fixed bonding between described telefault, insulation sleeve and the sensor outer housing, be provided with back-moving spring between described insulation sleeve and the coupling shaft.
Fixedly connected by screw thread between described magnetic core, coupling shaft and the sensor contact and be integral, be provided with bearing between described coupling shaft and the sensor outer housing, seal by plastic sealing cover between described sensor contact and the sensor outer housing.
Described elastic body and bearing connect by gluing.
Described bearing is connected by screw with guide pin bushing.
When the utility model was worked, because of varying aperture, the position L between two gauge heads can change, and this change in displacement passes to sensor by elastic body, and sensor is connected on the size finder, and detected value is shown.Because of adopting displacement transducer, telefault and magnetic core are sealed in the sensor separately, telefault and sensor outer housing link together, magnetic core and sensor contact link together, when described sensor senses device contact moves, the relative telefault of effect magnetic core by bearing is done axial displacement, seal with plastic sealing cover between sensor outer housing and the sensor contact, do not allow to be subject to the interference of external working environment in use, inductance value in use can not change, and the size of demonstration will be more stable.
The beneficial effects of the utility model are as follows:
Fine because of the sensor sealing property, in use can not exist because of inductance changes the variation that causes electric current, measurement size is stable.
