Structure of grinding machine controller

Abstract

The invention discloses a structure of a grinding machine controller. The structure comprises a bottom board, a case, a PCB (printed circuit board) assembly, a transformer and a power supply filter, wherein the PCB assembly, the transformer and the power supply filter are respectively arranged on the bottom board, the case covers the upper part of the bottom board and forms a sealed structure with the bottom board, the PCB assembly, the transformer and the power supply filter are positioned in the sealed structure, the PCB assembly comprises a PCB and a control element welded on the PCB, the PCB is in an irregular shape with a notch, the power supply filter and the transformer are arranged in the notch part of the PCB and are fixedly connected with the bottom board, and an insulation isolation board is arranged among the power supply filter, the transformer and the PCB assembly. The PCB assembly is effectively isolated from power supply devices such as the transformer, and noise interference of the power supply to the work of a control element is avoided, so the equipment operates more reliably, and the equipment operation stability is improved.

Description

technical field [0001] The invention belongs to the application field of electronic equipment, and in particular relates to a structure of a grinder controller. Background technique [0002] Surface grinding machine is a kind of precision grinding and polishing equipment. The material to be ground and polished is placed on a flat grinding disc. The grinding disc rotates counterclockwise, and the correction wheel drives the workpiece to rotate. Gravity pressure or other methods exert pressure on the workpiece. The discs are used for relative running friction to achieve the purpose of grinding and polishing. The grinding effect of the surface grinder mainly comes from two sources: one is continuous external addition, which is usually called free abrasive, and the second is that the abrasive particles are fixed in the grinding disc, which is often called fixed abrasive. [0003] There are many types of surface grinders, which are divided into small, medium and large according ...
