Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeter processing, in particular to a drilling machine for electromagnetic flowmeter processing. Background Art

[0002] An electromagnetic flowmeter is an instrument used to measure the flow of conductive liquids. It uses Faraday's electromagnetic induction principle to achieve flow measurement and is suitable for the metering and control of liquids such as water, sewage, acid-base solutions, and ore slurry. When a conductive liquid passes through an electromagnetic flowmeter installed in a pipeline, the flowing liquid will excite an electromagnetic field. When flowing through the conductive liquid, the electromotive force caused by the conductivity in the liquid and the movement of the magnetic field generate a voltage signal. The signal is proportional to the flow rate of the liquid. By measuring the size of this voltage signal, the flow rate of the liquid can be determined, and the flow rate can be calculated. At present, when using an electromagnetic flowmeter, two symmetrical holes for installing electrodes need to be set. When drilling holes, the existing electromagnetic flowmeter processing drilling machine usually requires manual support to drill the electromagnetic flowmeter, which causes the electromagnetic flowmeter to shake easily during processing and drilling, resulting in deviations in drilling and causing asymmetry of the two electrodes, affecting the measurement accuracy of the electromagnetic flowmeter.

[0033] Working principle: When using the device, the electromagnetic flowmeter to be processed is placed on the upper surface of the protective pad 15, and the positioning pin 16 is installed in an electrode hole in the electromagnetic flowmeter. The protective pad 15 effectively protects the electromagnetic flowmeter, and the positioning pin 16 effectively locks the position of the electromagnetic flowmeter.
