The invention particularly relates to a grinding machine based on gas phase change cooling, and belongs to the field of grinding tool equipment. The grinding machine comprises a grinding wheel body, a rotating shaft, a transmission pipeline, heat exchange equipment and a gear motor, a first groove is formed in one side of the grinding wheel body, a first inner pipe is arranged in the first groove, a flowing gap is formed between the first inner pipe and the bottom surface of the first groove, a first annular cavity is formed between the first inner pipe and the groove, the rotating shaft comprises an outer pipe and a second inner pipe arranged in the outer pipe, a second annular cavity is formed between the outer pipe and the second inner pipe, the second inner pipe is communicated with the first inner pipe, the first annular cavity is communicated with the second annular cavity, the transmission pipeline comprises an input pipeline and an output pipeline, the input pipeline is communicated with the second inner pipe, and the output pipeline is communicated with the outer pipe. Liquid cooling fluid flows in from the first inner pipe, absorbs heat generated by the end face and the side curved surface of the grinding wheel body when passing through the flowing gap and the first annular cavity and is vaporized in the flowing gap and the first annular cavity, and the grinding wheel body can be effectively cooled through latent heat of vaporization.
Description
technical field [0001] The present application relates to the field of abrasive equipment, in particular to a grinder based on gas phase change cooling. Background technique [0002] The grinding wheel is a bonded abrasive that is consolidated on the substrate to form a certain shape and a certain strength of the consolidated abrasive. In the process of grinding wheel grinding, due to the high-speed friction between the grinding wheel and the workpiece, a large amount of heat will be generated, which will cause the temperature of the grinding wheel matrix to rise sharply, resulting in deformation and damage to the joint between the abrasive and the matrix, and even lead to high-temperature instability of the abrasive grains. Oxidation and diffusion will cause abrasive wear of the grinding wheel and reduce the grinding characteristics of the grinding wheel. Therefore, it is often necessary to spray coolant to the grinding wheel and the workpiece to cool down. But for high-s...
