Abstract
The utility model relates to accessories of a machine tool, and specifically relates to a spindle with a heat dissipation cavity, which comprises a main spindle body which is of a cylindrical structure, and is characterized in that a penetrable cavity is arranged in the middle of the main spindle body, and the diameter of the cavity is 50-70% less than that of the main spindle body. The spindle has the advantages of good heat dissipation performance, low cost and long service life.
Description
Technical field
The utility model relates to machine tool accessories, specifically relates to a kind of main shaft.
Background technology
In the prior art, the main shaft of lathe all is that solid, such main shaft has the strong characteristics of rigidity, and when operation, it also has, and heat-sinking capability is poor, cost high, the shortcoming of easy annealing in addition, has influenced the service life of main shaft.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, provides that a kind of perfect heat-dissipating, cost are low, long service life is at main shaft---have the main shaft in heat radiation chamber.
The technical scheme of the utility model is achieved in that the main shaft with heat radiation chamber, comprises spindle main body, and spindle main body is a cylindrical structural, it is characterized in that: a cavity that penetrates is arranged in the middle of the described spindle main body.
Say that further the diameter of described cavity is the 50-70% of spindle main body diameter.
The beneficial effect of the utility model is: such main shaft has that perfect heat-dissipating, cost are low, the advantage of long service life.
