Problems solved by technology

[0002] In the prior art, the body of the ball electric spindle is mainly used to fix and install bearings, bearing housings, stators and other components, but as the shell of the spindle, it often cannot protect the normal operation of each component, especially for high-speed ball spindles. No circulating cooling system can be provided to reduce the temperature of the spindle when it is working
The aluminum water jacket assembly for the ball high-speed electric spindle has a complex structure, which is not conducive to the heat dissipation of the spindle, inconvenient installation, single function, and difficult to grasp the assembly accuracy
The air cylinder in the pneumatic tool unloading mechanism for the ball high-speed electric spindle has a complex structure, low sealing performance, and unstable transmission. Frequent tool changes are easy to damage or leak air.
The bearing seat assembly for the ball high-speed electric spindle has a single structure, difficult processing, inconvenient loading and unloading, and difficult to adjust the axial stability. After assembly, it will also affect the force of the pull rod, pull claw, etc., and the function of pulling and unloading the knife cannot be realized, and the service life is short, requiring frequent replacement. Therefore, the speed of the current ball electric spindle is not high, and the service life is not long.
