Abstract
The invention relates to a novel column inclination angle adjusting mechanism of a CNC (Computerized Numerical Control) gear shaping machine. The adjusting mechanism comprises a support shaft connecting a column with a lathe bed, and is characterized by further comprising semicircular arc support blocks symmetrically and fixedly mounted on bottom surfaces on two sides at the rear end of the column, an adjusting bearing plate arranged between the support blocks and the lathe bed, and an oil cylinder arranged close to the rear end of the column and used for connecting the column with the lathe bed; and under the condition that the semicircular arc support blocks are in direct contact with the upper end surface of the lathe bed, a pinion shaped cutter moves in the direction vertical to a working table. The inclination angle adjusting mechanism is designed on the basis of the sine function; and the connecting line between the center of the support shaft and the centers of the semicircular arc support blocks is equal to a sloping side, and the thickness of the adjusting bearing plate is equal to a right-angle side, so that the column inclination angle can be adjusted accurately through changing the thickness of the adjusting bearing plate. The adjusting mechanism is convenient to operate, and time-saving and labor-saving, and omits an angle gauge. In addition, the semicircular arc support blocks are compressed on the lathe bed through the adjusting bearing plate. Compared with the prior art, the adjusting mechanism shortens the distance between the column and the lathe bed, and increases the active area between the column and the lathe bed, thereby improving the contact rigidity and the working stability of the column and the lathe bed.
