The invention relates to the field of machine tools, in particular to a feeding device of the machine tool, which is suitable for the feeding device moving in a specified direction in machine tool equipment such as grinding machines and lathes. The grinding wheel table of the feeding device is fixed on the base, and the base is equipped with a work table, and the support plate and the slide block that can slide on the work table are installed on the top of the work table, and the oil inlet of the slide block is set on the slide block. The oil inlet of the support plate is set on the support plate, and the hydraulic oil ejected from the oil inlet of the slider and the oil inlet of the support plate on the support plate is supported to form an oil film between the sliding surface of the slider and the support plate of the workbench. Separate the slider and the table. The invention separates the slider and the workbench, and the hydraulic oil injected through the oil nozzle separates the slider and the workbench, forming a layer of diaphragm between the slider and the workbench, and the friction of the slider when it moves on the workbench is very high. Small, and the change of slider movement speed has little effect on the oil film thickness, and the oil film also has good vibration resistance.
Description
technical field [0001] The invention relates to the field of machine tools, in particular to a feeding device of the machine tool, which is suitable for the feeding device moving in a specified direction in machine tool equipment such as grinding machines and lathes. Background technique [0002] At present, the feeding device on the machine tool mainly adopts: the slider slides above the worktable, generally using a flat guide rail on one side and a V-shaped guide rail on the other side, or a pair of fixed rectangular guide rails parallel to each other. In recent years, in order to reduce the relative motion resistance between the slider and the table, many linear guide rails are used. However, for the above-mentioned feeding device, since the guide rails are in contact with each other, it is difficult to ensure high feeding accuracy if they move on the guide rails for a long time; The time is long, which reduces the production efficiency, and the gap between the contactin...
