Abstract

The utility model relates to a lathe rotary main shaft field specifically is a pivot cooling circuit. Be equipped with double -line or multi start thread on rotary main shaft's the outer diametral plane, form the helicla flute more than two, simultaneously, form the endless groove round whole circumference on rotary main shaft's the preceding tip external diameter face, endless groove and the intercommunication of the helicla flute more than two form the spiral route. Suit sleeve on the diametral plane outside is by helicla flute, endless groove and coordinate the enclosure space route that telescopic inner surface formed. The utility model relates to a similar double -line or multi start thread to increase helix angle is through the helicla flute of widening, in order to improve cooling water flow and speed.

Description

A kind of rotating shaft cooling circuit
Technical field
This utility model relates to machine tool rotary main shaft field, is specially a kind of rotating shaft cooling circuit.
Background technology
Machine tool chief axis is the axle driving workpiece or cutter to rotate on lathe, generally by main shaft, bearing and driving member (tooth Wheel or belt wheel) etc. composition spindle unit, in the machine be mainly used to support driving parts such as gear, belt wheel, biography Pass motion and moment of torsion.With front rotary shaft cooling circuit, cooling water flow velocity is restricted, actually used middle cooling effect Bad.
Utility model content
The purpose of this utility model is to provide a kind of rotating shaft cooling circuit, to improve cooling water flow and speed.
The technical solution of the utility model is:
A kind of rotating shaft cooling circuit, the outer diameter face of rotary main shaft is provided with two-wire or multi start thread, formed two with On helicla flute;Meanwhile, the leading section outer diameter face of rotary main shaft forms the endless groove around whole circumference, ring Shape groove and the helicla flute connection of more than two, form spiral channel.
Described rotating shaft cooling circuit, overlaps sleeved in outer diameter face, by helicla flute, endless groove and engagement sleeves The closing space path that the aperture surface of cylinder is formed.
Described rotating shaft cooling circuit, sleeve seals shape relative to rotary main shaft and is fitted and fixed with.
Described rotating shaft cooling circuit, after the form molding of more than two spiral channels, is respectively set as toward entering use Path enters to use path with multiple, and sets its screw twisted direction.
Advantage of the present utility model and providing the benefit that:
This utility model rotating shaft cooling circuit, uses two-wire or the helicla flute of multi start thread structure, single threaded Lead angle is less, and the lead angle of two-wire or multi start thread is bigger.The similar two-wire of this utility model design or Multi start thread, and increase lead angle, by the helicla flute widened, to improve cooling water flow and speed.
Accompanying drawing explanation
Fig. 1 is this utility model rotating shaft cooling circuit schematic diagram.
In figure, 1, helicla flute one;2, helicla flute two;3, endless groove;4, outer diameter face;5, rotary main shaft.
Detailed description of the invention
As it is shown in figure 1, the outer diameter face 4 of rotary main shaft 5 is provided with two-wire or multi start thread, form more than two Helicla flute, such as: helicla flute 1 or helicla flute 22.Meanwhile, in the leading section outer diameter face of rotary main shaft 5 Also forming the endless groove 3 around whole circumference, the endless groove 3 helicla flute with more than two connects, and forms spiral Path.Outer diameter face 4 is overlapped sleeved, the aperture surface of helicla flute, endless groove and mating sleeve formed Close space path, sleeve relative to rotary main shaft 5 utilize press-in or heat be embedded in into etc. method seal shape and be fitted together to Fixing.Article two, after the form molding of spiral channel more than, it is respectively set as toward entering with path and entering again with logical Road, and set its screw twisted direction.

Claims (4)
