Grinding machine with safety protection function

Abstract

The invention relates to the field of grinding machine machining, in particular to a grinding machine with a safety protection function. Comprising a machine body and a semiconductor chilling plate, a first motor is arranged on the machine body, a main shaft is coaxially fixed to the output end of the first motor, a grinding wheel is coaxially fixed to the free end of the main shaft, protective covers are arranged at the two ends of the grinding wheel, the protective covers are square, and the opening angle ranges from 30 degrees to 90 degrees. The cold end of the semiconductor chilling plate is opposite to the free end of the main shaft; a drying chamber is further formed in the machine body, and the hot end of the semiconductor chilling plate is arranged in the drying chamber; the heat dissipation fins are arranged between the main shaft and the protective cover and attached to the cold end of the semiconductor chilling plate. Comprising an object bearing table, the object bearing table is arranged below a grinding wheel and fixed to a machine body, and the hot end of a semiconductor chilling plate is fixed below the object bearing table. The problem that the grinding wheel expands due to thermal storage and bursts in the machining process of the grinding machine is solved.

Description

technical field [0001] The invention relates to the field of grinding machine processing, in particular to a grinding machine with safety protection function. Background technique [0002] Grinding machine is a machine tool that uses abrasive tools to grind the surface of workpieces, including headstock, tailstock, pendant, left and right slides, rotating upper plate, oil connection box, gauge, hydrostatic spindle, scale plate, tank chain, etc. element. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oilstone, abrasive belts, and free abrasives for processing, such as honing machines, superfinishing machine tools, belt grinding machines, grinding machines and polishing. There are many kinds of products processed in the machining industry, the size of the workpiece is different, and the processing accuracy is different. It is relatively required that the grinding wheel speed is different from the spindl...

Problems solved by technology

[0004] The above-mentioned technology uses water spraying to cool down the grinding disc during the processing process, but the instantaneous temperature drop will cause the grinding disc to expand with heat and contract with cold, which may cause the grinding disc to burst and cause safety accidents , the cooling process is not safe enough
