Abstract

The invention relates to a three-axis servo feed transmission structure of a machining center, which comprises a ball screw, a nut seat, a motor seat, a bearing seat, a lock nut, two groups of precision bearings supporting two ends of the ball screw, a coupling and a servo motor; an outer side seal and an inner side seal are respectively placed on two sides of each precision bearing, and a limit buffer collision block is placed on the ball screw which is near to the precision bearings; a gap is preserved in the position of an internal shoulder of a back-end lead screw of the ball screw; and the pre-stretched lock nut is placed at the tail end of the ball screw. The three-axis servo feed transmission structure has the benefits of improving the precision and the stability of servo transmission, having high universalization rate of parts, controlling the production cost, reducing the failure rate and facilitating the repair and the maintenance.

Description

technical field [0001] The invention relates to a machining center, in particular to a three-axis servo feed transmission structure of the machining center. Background technique [0002] Machining centers are widely used in the field of machinery manufacturing and processing, especially in the supporting processing of parts in the fields of automobiles, electronics, molds and aerospace technology. [0003] Depend on figure 1 It can be seen that the mechanical part of the machining center is mainly composed of the following components: the main part including the bed, the saddle, the worktable, the spindle box and the column 1, the X-axis servo feed drive 2, the Y-axis servo feed drive 3, and the Z-axis servo Feed transmission 4, spindle cutting transmission 5 and vertical movement balance transmission 6. Among them: the X-axis servo feed realizes the horizontal servo movement of the worktable, the Y-axis servo feed realizes the longitudinal servo movement of the worktable,...
