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.
Bearing housing components for ball high-speed electric spindles have a single structure, difficult processing, inconvenient assembly and disassembly, difficult adjustment of axial stability, and low heat dissipation
The through-hole structure of the shaft core for the ball high-speed electric spindle is unreasonable, which makes it inconvenient to assemble the tie rod and other accessories. Short life, frequent replacement and other shortcomings, so today's ball electric spindle speed is not high, and the service life is not long
