Abstract

The invention discloses a conveniently mounted and adjusted high-precision ball screw supporting structure which comprises a rear support (1), wherein a ball screw (4) is fixed on the rear support (1) through a rear locking nut (2) and a rear bearing (3); the front end of the ball screw (4) is fixed on a front support (7) through a front locking nut (5) and a front bearing (6); the structure is characterized in that: an external thread is arranged on one side of the ball screw (4) close to the front bearing (6); a locking nut (8) is in threaded connection with the external thread; a spacing sleeve (9) is sleeved between the front support (7) and the ball screw (4); and one end of the spacing sleeve (9) is butted against the front bearing (6) while the other end is butted against the locking nut (8). The ball screw supporting structure has the advantages of simple structure, smart design, convenience and quickness in mounting and adjusting, and capability of ensuring mounting precision.

Description

technical field [0001] The invention relates to a ball screw support structure, in particular to a ball screw support structure which is easy to install and adjust and can ensure precision. Background technique [0002] When installing the ball screw, its rear end needs to be fixed on the rear support part through the rear lock nut and the rear bearing, while the front part is fixed on the front support part through the front lock nut and the front bearing, and the front lock The nut needs to stretch the ball screw in the axial direction. In order to obtain higher installation accuracy and avoid its axial movement, it is necessary to process a step on the ball screw, and between the step and the front bearing. There is a spacer between them. In order to ensure accurate installation, it is usually necessary to measure the distance between the step and the front bearing on site after stretching the ball screw, and grind the spacer according to the obtained size, and then remo...
