Problems solved by technology

The detection method is primitive and the precision is not high, there are missed detection and false detection phenomenon
At the same time, the workload of operators is increased, the efficiency is particularly low, and it is difficult to meet the needs of large-scale production
Once there are missed inspections, false inspections, or unqualified products due to random inspections are used as genuine products, it will cause a series of serious consequences in the follow-up

Abstract

The invention discloses a device for automatically detecting spool displacement of an electromagnetic valve with high precision and a method thereof. The device comprises a work platform, an electromagnetic valve fixing bracket, a sensor bracket, a stepping motor, a high-precision displacement sensor and a signal detection and analysis control instrument. The device is characterized in that a placed electromagnetic valve can be fixed automatically and a sensor probe can extend to a detection part through the moveable sensor bracket. The position of the sensor is controlled by the stepping motor, the spool displacement of the electrified electromagnetic valve is detected by the high-precision displacement sensor, and the signal detection and analysis control instrument outputs a result that a product is qualified or not. The detection process disclosed by the invention is carried out automatically, the efficiency is high, the detection is reliable and high, the time and the labor are saved and a guarantee for overall detection of electromagnetic valve products is provided.

Description

technical field [0001] The invention relates to a device and method for automatically measuring the displacement of a solenoid valve core, belonging to the technical field of mechanical process equipment automation. Background technique [0002] Whether the solenoid valve core displacement is within the allowable range before and after energization determines whether the solenoid valve is qualified. Detecting whether the solenoid valve is qualified or not is an indispensable part of production and inspection. There is no automatic detection equipment at present, and it can only be detected manually. The detection method is generally to use a caliper with a thin needle to perform a measurement before and after power-on, and read the reading to determine whether it is within the allowable range. The detection method is primitive and the precision is not high, there are missed detection and false detection phenomenon. At the same time, the workload of operators is increased,...
