And understand the present invention, rather than to limit the present invention.
Embodiment:
As depicted in figs. 1 and 2, the present invention provides a kind of mainshaft mechanism of novel digital-control boring-milling machine, including axle bed 1,
It is equipped with main shaft 2 in the axle bed 1, bearing 15 is equipped between the axle bed 1 and main shaft 2, one end of the main shaft 2 is connected with main shaft
Motor 3, is connected with shaft coupling 16 between the spindle motor 3 and main shaft 2, the main shaft 2 is equipped with brake gear, the brake
Device includes two ring flanges 4 being disposed adjacent on main shaft, is respectively equipped with 5 He of brake disc seat on ring flange 4 described in two
Brake bar 6, and the brake disc seat 5 is equipped with brake disc 7, and the brake bar 6 is equipped with brake block 8, and the brake disc 7 is logical
It crosses screw to connect with brake disc seat 5, the brake block 8 is connect by screw with brake bar 6, the brake disc 7 and brake block 8
It is all made of high-intensitive, high-wearing feature Steel material；
As shown in Figures 2 and 3, in the present invention, the brake block 8 is in petal-shaped, and the center of the brake block 8 is installation
Seat 9, the mounting base 9 are connected with brake bar 6, and several sub- brake blocks 10 are equipped with around the mounting base 9, and the son is stopped
There are six vehicle pieces 10, and sub- brake block 10 described in six is disposed in an evenly spaced relation in mounting base 9 radially, the sub- brake block 10
For half isolated structures, and sub- brake block 10 includes pedestal 11, and the pedestal 11 is connected with mounting base 9, and pedestal 11 and mounting base 9
Integrally formed, the front end of the pedestal 11 bends downward to form bending segment 12, and the lower end forward fold of the bending segment 12 is formed

When spindle motor 3 remains static, exist between brake block 8 and brake disc 7 by 8 natural resiliency of brake block
Pretightning force.When artificially stirring 3 rotor of spindle motor, the frictional force as caused by pretightning force is overcome, it appears especially painstaking.When
After the energization of spindle motor 3 starts and reaches certain revolving speed, very big centrifugation can be all generated per a piece of sub- brake block 10 on brake block 8
Power；When centrifugal force overcomes the stiction between brake block 8 and brake disc 7 enough, brake block 8 will be detached from vertical direction
Brake disc 7, frictional force is no longer done work at this time.When spindle motor 3 is cut off the power, with the reduction of 3 revolving speed of spindle motor, centrifugation
The component of power is less than pretightning force, and brake block 8 returns to initial position again, and frictional force can generate huge resistance at this time, prevents master
3 rotor of spindle motor is remained in operation due to what inertia force generated.Frictional force overcomes inertia force to do work, brake disc 7 and brake block 8 it
Between generate a large amount of thermal energy so that motor speed is rapidly reduced to zero, frictional force becomes brake force at this time.Due to depositing for brake force
Greatly reducing the time of mower motor stopping brake.
