Abstract

The invention discloses an X-shaft ball screw nut transmission mechanism of a numerical control floor type boring and milling machine. The transmission mechanism comprises a ball screw nut transmission pair, an anti-backlash gear pair and a power source, wherein the anti-backlash gear pair comprises a pinion gear and a double-tooth anti-backlash gear which are linked with a power source output shaft; the ball screw nut transmission pair is a ball screw nut component and comprises a ball screw and a nut; a nut sleeve is arranged outside the nut; the double-tooth anti-backlash gear is arranged on the nut sleeve; and one end of the ball screw is fixed, while the other end is born. The transmission mechanism has the advantages of simple structure, low cost, high degree of standardization, short production cycle and high transmission precision.

Description

technical field [0001] The invention relates to the technical field of numerically controlled metal cutting machine tools, in particular to an X-axis ball screw nut transmission mechanism suitable for a numerically controlled floor boring and milling machine. Background technique [0002] At present, ball screw nut transmission is the main transmission type of CNC machine tools, but it has not been applied to the X direction of CNC floor boring and milling machines. The X-direction of the CNC floor boring and milling machine used to be driven by a rack and pinion mechanism. Although it is suitable for heavy loads, the structure is complex, the cost is high, the degree of standardization is low, the production cycle is long, and it is not conducive to further improvement of precision. [0003] The publication number is CN101382192, and the Chinese patent document published on March 11, 2009 discloses an anti-backlash transmission box. The technical solution adopted is: a righ...
