Description
Technical field
The present invention relates to a kind of lathe spindle, relate in particular to a kind of electric spindle of lathe.
Background technology
The structure of engine lathe electricity main shaft mainly has the following disadvantages at present:
At first, the lathe spindle cantilever is longer, influences the transmission accuracy of lathe spindle.
Secondly, the main shaft cooling system is occurring under the leakage situation, and in a single day prevention and flow-guiding structure do not cool off and leak, and then are easy to burn electric main shaft.
Once more, main shaft seal adopts a plurality of parts to unite to carry out, though can reach the effect of sealing, the parts that relate to are many, occurs easily leaking, and has improved cost.
Summary of the invention
The technical problem to be solved in the present invention provides the electric spindle of lathe structure that a kind of spindle drive precision height, cooling system are reliable, sealing is simple and reliable.
In order to address the above problem, the invention provides a kind of electric spindle of lathe, comprise main shaft, rotor, stator, water jacket, shell, drive end bearing bracket and rear end cap; Drive end bearing bracket and rear end cap are installed in the front and back end of described shell respectively, and bearing cap also is installed on the described drive end bearing bracket; Water jacket is sleeved in the described shell, and stator is sleeved in the described water jacket, and rotor is rotatable to be sleeved in the described stator, and main shaft is fixedly set in the described rotor, and the two ends of described main shaft are installed on described drive end bearing bracket and the rear end cap by bearing is rotatable respectively; Described water jacket and the contacted outer circumference surface of described shell are provided with and are used for water-cooling groove that stator is cooled off, be respectively arranged with a pair of sealing ring at described water jacket near on the excircle at two ends, also be respectively arranged with the water that is used to prevent in the water-cooling groove and be penetrated into inner seepage groove between every pair of sealing ring, described shell is provided with the weepage holes that links to each other with described seepage groove.
Preferably, also be provided with the labyrinth seal structure that embeds mutually with described bearing cap on described main shaft power output and the position that described bearing cap is connected.
The present invention has following advantage:
1, among the present invention, rotor and main shaft are become one, and on the clutch end labyrinth seal structure are set directly, replace the hermetically-sealed construction of former a plurality of parts, and it is a lot of that this just makes that the main shaft jib-length reduces, and improved the precision of main shaft rigidity and power output.
2, among the present invention; be provided with the seepage groove on the water jacket; and link to each other with weepage holes on the shell; when in a single day seepage takes place water jacket, the cooling liquid that leaks out at first enters the seepage groove, and discharges by weepage holes; not only play the effect of water conservancy diversion; and operating personnel can know and observe this leakage easily, can take measures very soon, have protected vitals such as stator, rotor and bearing to the full extent.
3, the seepage groove is set between every pair of sealing ring, not only can be with leakage cooling fluid water conservancy diversion, and also owing to adopt the double-layer seal protection, sealing effectiveness is stronger, before and after the water conservancy diversion sealing ring is set all, stronger to the protection effect of rotor, stator.
4, among the present invention, labyrinth seal structure is set directly on main shaft, replaces and use a plurality of seal members to seal, this just makes that hermetically-sealed construction is simple and reliable, and has saved manufacturing cost.
Description of drawings
Below in conjunction with accompanying drawing embodiments of the present invention are described further:
Fig. 1 shows a kind of electric spindle of lathe structural profile of the present invention schematic diagram;
Fig. 2 shows labyrinth seal structure section enlarged diagram of the present invention.
The specific embodiment
As shown in Figure 1, the invention provides a kind of electric spindle of lathe, comprise main shaft 1, rotor 2, stator 3, water jacket 4, shell 5, drive end bearing bracket 6 and rear end cap 7; Drive end bearing bracket 6 and rear end cap 7 are installed in the front and back end of shell 5 respectively, and bearing cap 8 also is installed on the drive end bearing bracket 6; Water jacket 4 is sleeved in the shell 5, and stator 3 is sleeved in the water jacket 4, rotor 2 rotatable being sleeved in the stator 3, and main shaft 1 is fixedly set in the rotor 2, and the two ends of main shaft 1 are respectively by bearing 9,10 rotatable being installed on drive end bearing bracket 6 and the rear end cap 7; Water jacket 4 and shell 5 contacted outer circumference surfaces are provided with and are used for water-cooling groove 43 that stator 3 is cooled off, on the excircle at the close two ends of water jacket 4, be respectively arranged with a pair of sealing ring 41, also be respectively arranged with the water that is used to prevent in the water-cooling groove 43 and be penetrated into inner seepage groove 42 between every pair of sealing ring 41, shell 5 is provided with the weepage holes 51 that links to each other with seepage groove 42.
Also be provided with on main shaft 1 clutch end and the position that bearing cap 8 is connected and labyrinth seal structures 11 that bearing cap 8 embeds mutually.
Among the present invention, rotor 2 is become one with main shaft 1, and on the clutch end labyrinth seal structure 11 is set directly, replaces the hermetically-sealed construction of former a plurality of parts, and it is a lot of that this just makes that main shaft 1 jib-length reduces, and improved the precision of main shaft 1 rigidity and power output.
