The periphery of one end is simultaneously abutted against with described drive end bearing bracket, and the other end in described first adapter sleeve is also connected with air bladder chuck.
Its further technical scheme is:
Positioned at periphery returning apparatus second adapter sleeve of described main shaft, described second adapter sleeve is connected with cylinder；
The periphery of described pulley end also clamping locking nut；
Described clutch shaft bearing group is a pair of adjacently positioned deep groove ball bearing, fills between each adjacently positioned deep groove ball bearing
Put clutch shaft bearing spacer ring.
Described second bearing group is adjacently positioned two teams pairing bearing, device the between each adjacently positioned pairing bearing
Two bearing spacers；
First groove is had on described drive end bearing bracket, the bearing cap abutting against with described drive end bearing bracket also has second recessed
Groove, boss portion and concave part；
Beneficial effects of the present invention are as follows:
Present configuration is simple, easy for installation, effectively achieves work by by air cooling one pipe device inside main shaft
Part air cooling in process and water-cooled, air cooling simultaneously and water-cooled execute from inside workpiece, substantially increase workpiece in processing
During accuracy, it is to avoid the problem of the accurate difference that conventional workpiece is led to by external equipment air cooling, water-cooled；Simultaneously
By rabbeting bearing cap, drive end bearing bracket and waterproof cover each other, and effectively achieve the present invention from interior by increasing " o " shape sealing ring
To outer waterproof and dustproof performance.By increase by two to pairing bearing, and respectively pairing bearing be installed as back to back contacts, make
Load action center is in outside the center line of each bearing, considerably increases by loading capability, and improves axial runout, and axle is jumped
Dynamic guarantee is 2～4um.
