The utility model discloses a machine head of a drilling and milling machine, which is composed of a machine head case, a main shaft sleeve, a main shaft, a fixture and a motor. In the sleeve hole, the motor and the main shaft sleeve are installed in the head box together, and it is characterized in that: the stator is located inside the rotor and is fixed on the main shaft sleeve, the rotor is fixed on the main shaft, the rotation of the rotor directly drives the main shaft to rotate, and the lifting handle wheel The main shaft sleeve is driven to move up and down, and the stator on the main shaft sleeve and the rotor fixed on the main shaft move up and down together as a whole. By arranging the stator of the motor inside the rotor, the utility model doubles the effective magnetic field area between the stator and the rotor, increases the torque of the motor several times, and at the same time has more pole pairs, and the rotational speed is low. The required torque can be achieved without gear deceleration, the rotor and the main shaft are directly connected, the structure is simple, the cost is low, the movement process is small, and the noise is low.
Description
Technical field
The utility model relates to arrive a kind of milling machine more particularly to a kind of head of drilling and milling machine, belong to field of mechanical technique.
Background technique
Milling machine is a kind of common tool of machining.Milling machine is usually made of head box 4 with rack, groundwork portion
Divide in head.Existing drilling and milling machine head, basic structure is as schemed, and motor casing 3 is provided with stator 2, and rotor 1 is in the stator
Between, it drives the pinion gear 5 on motor shaft to rotate by motor shaft 14, imparts power to the spline housing 7 equipped with gear wheel 6, flower
Key set 7 rotates in cabinet 4 under the support of upper bearing (metal) 13 and lower bearing 12, and the gear 8 of lifting handle drives on collar bush 9
Lower movement, while also being moved up and down with collar bush 9 loaded on the main shaft 10 in collar bush 9, and the spline on 10 top of main shaft also with
Spline housing 9 rotates, the rotation and move up and down for thus driving the fixture 11 loaded on 10 lower section of main shaft to realize that milling needs
Function.The shortcomings that this head is, motor uses traditional structure, and for rotor 1 inside stator 2, diameter is smaller, rotor 1 and fixed
Effective magnetic field area very little between son 2, motor torque very little, simultaneously because area is small, number of magnetic pole pairs are few, and general only two pairs
Several or four pairs of poles, revolving speed is high, therefore gear wheel 6 can only be driven to reduce revolving speed by pinion gear 5, increases torque, gear wheel 6
Power can only pass to main shaft by spline housing 7, and the transmission system cost of this structural shape is very high, and noise is big, easily grind
Damage.
Summary of the invention
For defect existing for existing drilling and milling machine head, the utility model proposes a kind of improved technical solutions.
The utility model is accomplished in the following manner: a kind of head of drilling and milling machine, by head box, collar bush, main shaft,
Fixture, motor are constituted, and the main shaft is rotatably mounted in collar bush, and one end installs fixture, the other end protrudes from main shaft
Set is outer, and the head box is equipped with main shaft sets of holes, and collar bush is installed in the main shaft sets of holes on head box, motor and collar bush
It is installed in head box together, it is characterised in that: the stator of the motor is located at internal rotor, is fixed on collar bush, turns
Son is fixed on main shaft, and rotor rotation directly drives main shaft rotation, and lifting handle gear drives collar bush to move up and down, while band
The dynamic stator being fixed on collar bush and the rotor being fixed on main shaft integrally move up and down together.
The stator of motor, is loaded on the inside of rotor by the utility model, and increasing at double is effective between stator and rotor
Magnetic field area, the torque of motor increase several times, while having more number of magnetic pole pairs, and revolving speed is lower, do not need The gear deceleration, i.e.,
It can reach required torque, rotor and main shaft are directly connected to, and structure is simple, and at low cost, motion process abrasion is small, and noise is low.
Detailed description of the invention
The structural schematic diagram of the existing drilling and milling machine head of Fig. 1；
The structural schematic diagram of Fig. 2 the utility model.
Specific embodiment
As shown in Fig. 2, a kind of head of drilling and milling machine is made of head box 4, collar bush 9, main shaft 10, fixture 11, motor, it is main
Axis 10 is rotatably mounted in collar bush 9, and one end installs fixture 11, the other end protrudes from outside collar bush 9.
Head box 4 is equipped with 9 hole of collar bush, and collar bush 9 is installed in 9 hole of collar bush on head box 4, and main shaft 10 is pacified
In collar bush 9.
The rotor 1 of the adapted power motor of drilling and milling machine head is two parts separated with stator 2, and wherein stator 2 is fixed
On collar bush 9, rotor 1 is then fixed on the upper end of main shaft 10, and is located at stator 2 inside rotor 1,
Rotor 1, which rotates, directly drives main shaft 10 to rotate, and the side wall of collar bush 9 sets lifting handle gear, to drive collar bush 9
Move up and down, at the same drive the stator 2 that is fixed on collar bush 9 and the rotor being fixed on main shaft 10 1 it is whole together on move down
It is dynamic.
The utility model in actual use, only head need to be installed on milling machine on can work.It simultaneously can also root
It can be used on drilling machine when the special fixture 11 of milling machine is replaced with drilling attachment 11 according to needs.
