Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The utility model provides an electricity main shaft head device of polishing, install cutter 5 in joint 14 department through handle of a knife 4, the cylinder of polishing 1 changes the inside pressure of joint 14 through pipe 6, the installation of handle of a knife 4 is accomplished to the formation pressure differential, the inside toroidal cavity of axle sleeve 11, the through-hole that the outside annular of axle center distributes, the cavity of the inside below of main shaft 8 and the cavity at joint 4 center communicate each other, the through-hole floats inside equal directional toroidal cavity within 5 degrees, pipe 6 passes through the seal bolt and the inside toroidal cavity intercommunication of axle sleeve 11, thereby make the cylinder of polishing 1 can change the pressure completion handle of a knife 14 installation and dismantlement of the inside of joint 14, driving motor installs in the inside top of electric main shaft 2, shaft coupling 7 docks with driving motor's drive shaft and main shaft 8 respectively through the butt joint flange, because shaft coupling 7 is scalable universal coupling, the middle part is the universal joint, both sides are the universal joint, when main shaft 8 through the swing of passive relocation mechanism 9 and the unsteady output power of fluctuation from top to bottom, thereby make main shaft 8 drive cutter 5 drive tool 5 to float man-hour, the biggest unsteady range of passive relocation mechanism 9 is 5 degrees, can satisfy the flexible work rule plane and irregular curved surface, the flexible work of polishing 2 electricity air moves the angle change of polishing and tracks up the unsteady angle of the floating of the grinding and tracks up when the flexible grinding mechanism and changes in the unsteady angle of the unsteady mechanism of the electricity, the floating of the main shaft and change, the floating of the main shaft of polishing, the floating.

The driven floating mechanism 9 makes the main shaft 8 swing in the shaft sleeve 11 through the shaft center 10, the swing amplitude is limited within 5 degrees through the limitation of the shaft sleeve 11, the main shaft is reset through the reset mechanisms 12 on the upper side and the lower side after swinging or floating, and the corrugated pipe 13 is used for closing the gap between the driven floating mechanism and the main shaft 8.
