Description
Technical field
The present invention relates to CNC milling machine apparatus field, more particularly to a kind of CNC milling machine high-speed main spindle mechanism.
Background technology
High-speed main spindle in CNC milling machine in the process of running caused vibration to meetings such as part processing precision, surface quality
Cause serious influence.Single-row, Biserial cylindrical roller bearing is used in existing high-speed main spindle, its dynamic balancing effect is poor, and work
Main shaft temperature rise in work, noise are big.
The content of the invention
The problem of for shortcomings and deficiencies in the prior art, the present invention propose a kind of CNC milling machine high-speed main spindle mechanism,
Dynamic balancing effect is good, using paired angular contact bearing, has the advantages that temperature rise is low, noiseless.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of CNC milling machine high-speed main spindle mechanism, including pull bar, main shaft, sleeve, tooth abdomen nut, belt pulley and position-arresting disk, it is described
Pull bar is arranged in spindle hole, and sleeve, tooth abdomen nut, belt pulley and position-arresting disk are sequentially arranged on main shaft, and sleeve one end passes through
The main shaft shaft shoulder is fixed, and upper bearing (metal) and lower bearing is provided between sleeve and main shaft, the upper and lower bearing is using diagonally engagement shaft
Hold, the sleeve lower end is provided with adpting flange by end cap seal, sleeve outer wall.
Further, the position-arresting disk is fixed on main shaft by holding screw.
Further, bearing spacer is provided between the upper bearing (metal) and lower bearing.
Further, the belt pulley is fixed on main shaft by key.
The present invention has the advantages that：The present invention is simple in construction, easy to assembly, using paired angular contact bearing, tool
There is the advantages that temperature rise is low, noiseless.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
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 present invention can reduce main shaft 2 and turn in high speed by being arranged to diagonally contact upper and lower bearing between sleeve 3 and main shaft 2
Temperature rise when dynamic, and noiseless, dynamic balancing effect is good, improves CNC milling machine milling quality.
