Summary of the invention
Therefore, the purpose of the utility model provides a kind of main shaft that can cool off, and this main shaft can cool off, and can not produce thermal deformation, can work long hours and does not influence the precision of processing.
Another purpose of the utility model provides a kind of main shaft that can cool off, and this main axle structure is simple, is convenient to realize, can extensively send out in the lathe separately that is applied to existing machinery processing, the milling machine.
For achieving the above object, the utility model is to realize like this.
A kind of main shaft that can cool off, the one of which end is connected with rotating cylinder, and the other end is connected with cutter head, it is characterized in that said main shaft is a hollow structure, and the main shaft set inside has cooling line.Through cooling line main shaft is cooled off, can cool off main shaft in time, apace, reduce the operating temperature of main shaft, the peripheral thermal deformation of the main shaft of avoiding the main shaft long-term work to cause helps ensureing the precision and the reliability of processing.
Said cooling pipe has inside and outside two, is sheathed in the main shaft, be positioned at the alignment of shafts for gas pipeline so that dispel the heat fast, near main shaft be fluid pipeline so that the heat of fast Absorption main shaft can fully cool off main shaft.
Said main shaft, its end that connects cutter head has handle of a knife, and said cooling pipe is connected with handle of a knife, is convenient to the cooling of cutter head and handle of a knife.
Said rotating cylinder is provided with choke valve in it, choke valve is connected on the cooling pipe, so that the effect of control cooling.
Above-mentioned rotating cylinder also is provided with threeway and straight joint in it, straight joint is connected to three outlets of threeway, is convenient to realize the circulation of cooling off reach favorable cooling effect.
The utility model adopts this structure, can main shaft be cooled off effectively, avoids the main shaft periphery thermal deformation to occur, and the precision that makes main shaft can keep processing works long hours, thereby has improved working (machining) efficiency and reliability.
And the utility model is simple in structure, practical, realizes easily, can be widely used in existing mechanical processing with on the main shaft.

Fig. 2 is the structural representation of cooling pipe in the utility model rotating cylinder.
The structural representation that Fig. 3 realizes for the utility model.
The specific embodiment
Shown in accompanying drawing, the practical implementation of the utility model is elaborated.
As shown in Figure 1, the utility model is embodied as a kind of main shaft that can cool off 3, and the upper end was connected with rotating cylinder 2 when it was used, and the upper end of rotating cylinder 2 is provided with pressurized cylinder 1 again, so that product is processed; The lower end of main shaft 3 is connected with cutter head 4; Simultaneously, main shaft also is connected with motor 5, and motor 5 drives main shaft 3 through belt pulley 6 and rotates, and wherein, belt pulley 6 is installed in the main spindle box 7, and main shaft 3 passes main spindle box 7, and motor 5 is arranged on the top of main spindle box 7, is supported by main spindle box 7.
In conjunction with shown in Figure 3, an important feature of the utility model is: main shaft 3 is hollow structure, and main shaft 3 set inside have two cooling lines 31,32.Cool off through 31,32 pairs of main shafts 3 of these two cooling lines, can cool off main shaft 3 in time, apace, reduce the operating temperature of main shaft, the peripheral thermal deformation of the main shaft of avoiding the main shaft long-term work to cause helps ensureing the precision and the reliability of processing.
Cooling pipe 31,32 has inside and outside two, is sheathed in the main shaft respectively; Wherein cooling pipe 32 is positioned at the alignment of shafts, is gas pipeline, so that dispel the heat fast; Cooling pipe 31 is near main shaft 3; The heat of fast Absorption main shaft is fluid pipeline, so that can fully cool off to main shaft.
The end that main shaft 3 connects cutter head 4 has handle of a knife 41; Connect cutter heads 4 through handle of a knife 41, wherein cooling pipe 32 also with handle of a knife 41 in be connected, also have the cooling duct around the handle of a knife 41; Cooling pipe 32 is connected to this cooling duct, is convenient to the cooling of cutter head 4 and handle of a knife 41.
In order to control the cooling of main shaft better, in conjunction with shown in Figure 2, choke valve 25 is set in the rotating cylinder 2, choke valve 25 is connected on the cooling pipe 32, so that the effect of control cooling.
And also be provided with threeway 23 in the rotating cylinder 2 and be connected in three outlets of threeway 23, be convenient to realize the circulation of cooling off, control cooling effect with 21,22,24, three straight joints 21,22,24 of straight joint.
The top of rotating cylinder 2 also is provided with a blasthole 8, can in cooling pipe 31 or 32, import water through changing the hole, carries out the cooling of main shaft 3.
Like this, can carry out water, oil from main shaft inside; The cooling of gas begins from the alignment of shafts, and water and oil are from top to bottom to cool off; Gas is convenient to cool off main shaft then from bottom to top, the operating temperature of control main shaft; Ensure that main shaft can work, can not produce thermal deformation, ensure the precision and the reliability of processing.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
