Abstract

The invention provides a milling machine spindle. The milling machine spindle comprises a spindle sleeve, a first bearing, a second bearing, a spindle core, a first labyrinth end cover and a second labyrinth end cover. The first bearing and the second bearing are correspondingly sleeved with the front and rear ends in the spindle sleeve. The spindle core is sleeved with the first bearing and the second bearing. The first labyrinth end cover and the second labyrinth end cover are correspondingly arranged at the front and rear ends of the spindle sleeve. A first step surface for limiting the first labyrinth end cover is arranged on the portion, at the front side of the first labyrinth end cover, of the spindle core. A first nut for limiting the second labyrinth end cover is arranged on the portion, on the rear side of the second labyrinth end cover, of the spindle core. The inner walls of the first bearing and the second bearing each are a taper with a big front end and a small rear end.A tapered surface matched with the tapered inner walls of the first bearing and the second bearing is arranged on the spindle core. According to the milling machine spindle, the tapered bearings withthe inner walls with the big front ends and the small rear ends are arranged between the spindle sleeve and the spindle core, and the tapered surface matched with the tapered inner walls of the bearings is arranged on the spindle core, so that assembly positioning is facilitated and assembly precision is improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a milling machine spindle. Background technique [0002] A CNC milling machine refers to a machine tool that can mill a workpiece with a spindle. Its main components usually include a machine base, a worktable, a spindle, a spindle drive motor, a feed drive motor, and a fixture for fixing the workpiece; during operation, the spindle rotates The main movement is the main movement, and the relative movement between the workpiece and the spindle is the feed movement. A cutterhead is installed at the front end of the spindle, and the cutterhead is driven to process the workpiece through the rotation of the spindle. The main shaft of the existing milling machine is not only complicated in structure and not easy to assemble, but also has low assembly precision, high manufacturing cost, and poor cutting ability. [0003] Therefore, the prior art still needs to be improved and develop...
