Machine tool eccentric main shaft with high bearing capacity and high rotating speed

Abstract

The invention discloses a machine tool eccentric main shaft with high bearing capacity and high rotating speed. The machine tool eccentric main shaft is composed of a main shaft mechanism and a motor mechanism, and is characterized in that the main shaft mechanism comprises a shaft core, a shaft core gland, a front outer blocking cover, a front gland, a sleeve flange, a front inner gasket, a rear outer gasket, a rear bearing gasket, a bearing locking nut, a sleeve and a sealing ring. According to the machine tool eccentric main shaft, the highest rotating speed is 4500 rpm, and the rotating shaft core of a main shaft box is eccentric from the sleeve, so that the cutting center distance is reduced, and the size of a cut monocrystalline silicon wafer is enlarged to 210. Due to the special bearing configuration, the main shaft has the characteristics of high rotating speed, high bearing capacity and low noise relative to an original shaft box. The sealing ring is tightly attached to the shaft core gland and rotates and rubs, so that impurities are prevented from entering the main shaft. A very few impurities entering the front end are attached to the surface of the front gland, and compressed air overflows from an inner hole of the front outer blocking cover and an air gap of the shaft core gland after being filled with an air storage groove, takes away the impurities on the surface of the front gland and prevents the impurities from entering the main shaft.

Description

technical field [0001] The invention relates to the technical field of solar silicon chip cutting, in particular to an eccentric spindle of a machine tool with high load capacity and high rotation speed. Background technique [0002] The photovoltaic manufacturing industry is developing well, product quality is steadily improving, and categories are gradually becoming larger. Large-size silicon wafers have obvious advantages in cost and efficiency, which can help downstream supporting manufacturers to increase efficiency and reduce costs. Large size silicon wafer 210 / 182 is a new trend in the current industry. The mortar wire cutting machine has a large stock, and the maximum processing size is M6 (166). Although the cost of mortar wire cutting machine is low, its disadvantages are obvious. On the one hand, the cutting speed is slow, the energy consumption ratio is low, and there is a serious waste of mortar; on the other hand, the existence of the sandblasting device tak...
