The invention relates to the technical field of liquid level detection, in particular to a method for manufacturing a cambered surface liquid level ruler scale of a semicircular liquid level indicator, which comprises the following steps of: mapping the cambered surface liquid level ruler scale on a concave semi-cylindrical cambered surface on a base into a plane image scale on an opposite surface of the semi-cylindrical cambered surface in a model space of drawing software; and forming an electronic file. Before marking, the electronic file is imported into an industrial control computer connected with a galvanometer scanning type laser marking machine, the workpiece base is placed on a working table of the laser marking machine, and the arc surface of the inwards-concave semi-cylinder faces upwards; and the laser scanning head is adjusted to enable a laser projection point to be positioned on the highest quadrant point of a circle where a semicircular groove arc intersecting line formed by intersecting the concave semi-cylindrical cambered surface on the base and the accommodating groove is positioned, so that the required cambered surface liquid level ruler scale can be etched on the concave semi-cylindrical cambered surface. Compared with the parallel etching effect of a workbench type laser marking machine, the method for manufacturing the scales of the cambered surface liquid level ruler has higher working efficiency and better definition.
Description
technical field [0001] The invention relates to the technical field of liquid level detection, in particular to a method for manufacturing the scale of the curved liquid level scale of a semicircular liquid level indicator. Background technique [0002] Liquid level detection has a wide range of needs in daily life. In general, liquid level detection methods can be divided into two categories: direct detection and indirect detection. Due to the complexity of measurement conditions and the convenience of data collection, indirect measurement is mostly used for liquid level detection at present, that is, the liquid level signal is converted into other related signals for measurement, such as pressure method, buoyancy method, electrical method, thermal method, etc. The disadvantage of indirect detection is that there are problems such as interference noise or zero point drift in the secondary signal, which is the advantage of direct detection. In the early days, the data coll...
