Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a linear rail column. Background Art

[0002] When some existing mechanical processing equipment (such as drilling machines, milling machines, etc.) processes workpieces, it is required that the tool can move in the vertical direction. The existing implementation method is to set the tool on a vertically arranged linear rail column and drive the tool to move up and down through the linear rail column.

[0003] Among them, the existing linear rail column includes a base, on which a guide rail and a lifting seat are provided, and on the lifting seat a slider is provided. The lifting seat is guided by the cooperation of the slider and the guide rail on the base, and the up and down movement of the lifting seat is driven by a motor and a ball screw mechanism.

[0004] During long-term use, the existing linear rail column will wear due to the long-term friction between the slider and the guide rail, which will increase the gap between the guide rail and the slider. At the same time, the matching gap between the screw nut and the screw will also increase due to friction, which will eventually lead to a decrease in the movement accuracy of the linear rail column. Summary of the invention

[0023] In this embodiment, the lifting seat 3 is longer, so that a more stable fit is formed between the lifting seat 3 and the guide rail 2, so that the lifting seat 3 has better stability when moving up and down.

[0024] The lifting seat 3 is provided with a spindle 5 and a driving motor 10 for driving the spindle 5 to rotate. The lifting seat 3 is provided with a spindle box for mounting the spindle, which is cylindrical and located outside the spindle 5.
