Abstract
The utility model provides a device for measuring the positions of three-phase bimetallic strips of a thermal relay. The device comprises an electric cylinder, an electric cylinder slide block, a test probe and a display device, wherein the upper part of the electric cylinder is connected with the display device, the electric cylinder slide block is slidably connected with the surface of the electric cylinder, the test probe is connected with the bottom of the electric cylinder slide block; the test probe comprises a main body, a needle-shaped part extending outside from the main body and a probe arranged on the top of the needle-shaped part. The accurate positions among the bimetallic strips are measured by the test probe and displayed in the display device, and the measurement accuracy is improved, and the measurement error due to product differentiation is reduced.
Description
Technical field
The utility model relates to electromechanical equipment and manufactures field, specifically a kind of device of measuring electrothermal relay three-phase bimetallic strip position.
Background technology
Electrothermal relay is to produce heat by the electric current that flows into thermal element, makes the bimetallic strip generation deformation of different expansion coefficient, when deformation reaches certain distance; just promote connecting rod action, control circuit is disconnected, thereby make contactor dead electricity; main circuit disconnects, and realizes the overload protection of motor.Particularly, in existing electrothermal relay, generally include some three-phase bimetallic strips arranged side by side, this three-phase bimetallic strip is formed by the sheet metal spreading of two kinds of different heat expansion coefficients, when electromotor overload, electric current by heater element surpasses setting current, three-phase bimetallic strip is heated and is bent upwards disengaging buckle, and normally closed contact is disconnected.Because normally closed contact is to be connected in the control circuit of motor, its disconnection can make the contactor coil power-off of joining with it, thereby contactor main contacts disconnects, and the main circuit power-off of motor, has realized overload protection.Electrothermal relay is as the overload protection element of motor, and little with its volume, simple in structure, low cost and other advantages is widely applied aborning.
At present in the production run of electrothermal relay, the position of measuring three-phase bimetallic strip is all generally the method for utilizing visual inspection, surveyed product is taken vertical view and measured its position, because sheet metal can not guarantee definitely perpendicular to surface level, so this traditional test mode has affected test accuracy greatly.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, a kind of device of measuring electrothermal relay three-phase bimetallic strip position is provided, the measuring error that has improved the accuracy measured and caused due to product differentiation.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of device of measuring electrothermal relay three-phase bimetallic strip position, comprise electric cylinder, electric cylinder slide block, test probe and display device, the top electrical connection of electric cylinder has display device, and electric cylinder surface sliding is connected with electric cylinder slide block, and the bottom of electric cylinder slide block is connected with test probe; Test probe comprises main part, independently the extended needle-like of body portion and the probe that is positioned at needle-like portion end.
Further, the bottom of electric cylinder slide block is bound piece by gauge head and is connected with test probe.
A kind of device of measuring electrothermal relay three-phase bimetallic strip position of the utility model, utilize test probe measure the accurate location between each bimetallic strip and show in display device, the measuring error that has improved the accuracy measured and caused due to product differentiation.
