Abstract
A structure for a machine-tool rotating spindle comprises a base. A spindle bearing is mounted on a bearing seat on the base. The spindle is mounted on the spindle bearing. A worm is matched with a worm wheel connected with the spindle. The special high-precision spindle bearing is adopted to locate the spindle, rotating precision is guaranteed by the special high-precision spindle bearing, the whole structure is simple to process and assemble, workload of manual scraping is low, and precision is easy to guarantee. By the machine-tool spindle, rotating precision can be increased by one grade.
Description
Technical field
The present invention relates to a kind of structure of the rotary main shaft for machine industry, it is simple to be specifically related to a kind of processing, the machine tool main shaft structure that running accuracy is high.
Background technology
Traditional platen main shaft is to position to guarantee its running accuracy by straight hole or taper hole, and the shortcoming of its maximum is large in processed complex, positioning accuracy workload unstable, artificial scraping.
Summary of the invention
The invention provides a kind of little machine tool main shaft structure of workload simple, stable, the artificial scraping of positioning accuracy of processing.
The object of the present invention is achieved like this: a kind of machine tool main shaft structure, comprise base, and main shaft bearing is installed on the bearing block on the base, and main shaft is installed on the main shaft bearing, and worm and wheel matches, and worm gear is connected with main shaft.Main shaft bearing is high-precision bearing, and its precision is to be unified into using bearing by three of precision corner contact ball bearing assembly, and its precision is the P4 level.
Machine tool main shaft structure provided by the invention adopts the special high-accuracy main shaft bearing that main shaft is positioned, and running accuracy is guaranteed that by the special high-accuracy main shaft bearing total is processed, assembling is simple, and the workload of artificial scraping is little, the easier assurance of precision.Adopt machine tool chief axis of the present invention, running accuracy can improve the precision one-level.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of machine tool main shaft structure comprises base 1, and main shaft bearing 2 is installed on the base 1, and main shaft 3 is installed on the main shaft bearing 2, and worm screw 4 is matched with worm gear 5, and worm gear 5 is connected with main shaft 3.
Main shaft bearing 2 is high-precision bearing, and its precision is to be unified into using bearing by three of precision corner contact ball bearing assembly, and its precision is the P4 level.
Operation principle is as follows: main shaft 3, main shaft bearing 2, bearing block 1, base 1, worm gear 5, worm screw 5 are assembled; Integral body after the assembling is connected with lathe by base 1; Rotarily drive 3 rotations of worm gear 5 and main shaft by worm screw 5.
