Further, the belt pulley is fixed on main shaft by key.
The utility model has the advantages that：The utility model is simple in construction, easy to assembly, using paired angular contact
Bearing, there is the advantages that temperature rise is low, noiseless.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As illustrated, a kind of CNC milling machine high-speed main spindle mechanism, including pull bar 1, main shaft 2, sleeve 3, tooth abdomen nut 4, skin
Belt wheel 5 and position-arresting disk 6, the pull bar 1 are arranged in the hole of main shaft 2, and sleeve 3, tooth abdomen nut 4, belt pulley 5 and position-arresting disk 6 are successively
On main shaft 2, the one end of sleeve 3 is fixed by the shaft shoulder of main shaft 2, and upper bearing (metal) 21 and lower axle are provided between sleeve 3 and main shaft 2
22 are held, the upper and lower bearing uses paired angular contact bearing, and the lower end of sleeve 3 is sealed by end cap 11, and the outer wall of sleeve 3 is set
There is adpting flange 31.
The position-arresting disk 6 is fixed on main shaft 2 by holding screw 41.
Bearing spacer 23 is provided between the upper bearing (metal) 21 and lower bearing 22.
The belt pulley 5 is fixed on main shaft 2 by key.
Specifically, described high-speed main spindle mechanism is fixed on main spindle box by the adpting flange 31 on the outer wall of sleeve 3, knife
Tool is rotated on the cone-shaped inner hole of main shaft 2 by motor driven belt pulley 5, is turned at a high speed so that main shaft 2 and cutter are done
Dynamic, the utility model diagonally contacts upper and lower bearing by being arranged between sleeve 3 and main shaft 2, can reduce main shaft 2 in height
Temperature rise when speed rotates, and noiseless, dynamic balancing effect is good, improves CNC milling machine milling quality.
