Abstract
The utility model discloses a direct-driven cutter head which comprises two torque motors with outer rotors, a swing head main shaft sleeve and a stator supporting frame. Stators of the torque motors, stator cooling sleeves and the stator supporting frame are in an integrally embedded structure. The swing head main shaft sleeve are integrated with the rotors of the torque motors so as to avoid the problem of poor rigidity caused by threaded connection and reduce the size of the cutter head at the same time. Moreover, a pneumatic forceps holder band-type brake system of an outrigger shaft type of the swing head main shaft sleeve is used to replace a hydraulic band-type brake mechanism to reduce manufacturing cost and improve responding speed.
Description
Technical field
The utility model relates to a kind of milling head, relate in particular to a kind of be applied to the 5-shaft linkage numerical control lathe directly drive milling head.
Background technology
Present directly drive the outer rotor torque motor that milling head adopts minute body structure more, promptly the pendulum mass structure of torque motor and milling head is separated, and links together through bolt.As shown in Figure 1; Typical split structural capacity torque motor directly drives milling head; Comprise inner torque motor coolant jacket 4 ', the yaw collar bush 6 ' of coolant jacket is installed, and torque motor stator 3 ', rotor 2 ', be positioned at the band-type brake mechanism 1 ' that rotor exterior is used to brake.
At present, both at home and abroad as the milling head that all drives in the development outer rotor torque motor of enterprise such as western Tyke or research institute, but problem is that divide the milling head of body structure because structure limits, its rigidity, intensity, precision stability are all relatively poor, and assembly technology is more complicated also.In order to obtain bigger moment of torsion, its structure is also bigger, thereby makes that the volume of whole execution unit is bigger.In addition, the hydraulic contracting agency cost that divides the body structure milling head to adopt is high, and the response time is slower.
The utility model content
The technical problem that the utility model solves just provides a kind of milling head that directly drives, and solves that traditional split structural rigidity is relatively poor, intensity is lower, in order to obtain need to increase the yaw volume than high pulling torque, the problem of influence use.
In order to address the above problem; The utility model provides a kind of milling head that directly drives; Comprise two outer rotor torque motor, yaw collar bush and stator support frame; Said outer rotor torque motor comprises torque motor stator, torque motor rotor; Said outer rotor torque motor also comprises and is attached to the outside stator coolant jacket of said torque motor stator, and said torque motor stator, stator coolant jacket and stator support frame are whole nesting type structure, and said yaw collar bush and torque motor rotor integrate.
Preferably, the utility model also has following characteristics:
Said stator coolant jacket is provided with a few font circulation cooling baths.
Preferably, the utility model also has following characteristics:
The said milling head that directly drives also includes and is positioned at the said stator coolant jacket outside, is positioned at the pneumatic clamp band-type brake system of the overhanging formula in the said yaw collar bush outside.
Preferably, the utility model also has following characteristics:
The said torque motor rotor that is integrated on the said yaw collar bush is that permanent magnet is SMD.
Pass through technique scheme; The whole nesting type structure outer rotor torque motor of the utility model is directly driven milling head; Owing to adopt the structure of rotor and yaw collar bush one, thereby have higher rigidity, intensity, better precision stability than the split outer rotor milling head of prior art; Structure itself takes up room little, and existing branch body structure milling head has higher moment of torsion, and mechanical advantage is higher.In addition, this structure adopts pneumatic clamp band-type brake system to compare the clamp band-type brake of hydraulic principle, has lower entire system cost, and it is convenient, compact to design to install, and dead electricity is stepped up automatically, and the reaction time is short, clean environment firendly.Simultaneously because whole nesting type structure, overhanging formula clamp band-type brake configuration saves the space of water brake mechanism of prior art torque motor rotor exterior, can be littler for the milling head volume of same torque torque motor.Particularly in the machine tool industry, the performance parameter equal volume is little just to have bigger advantage.In addition; The SMD rotor of the permanent magnet of the utility model directly is integrated on the yaw collar bush; Be the execution unit that torque motor directly can drive milling head, saved intermediate connecting ring joint, fixing link, zero transmission effect is more obvious; Do not need the high accuracy drive disk assembly and adjustment process is installed, better guaranteed transmission accuracy and mechanism's operational reliability.

The specific embodiment
The utility model has been constructed a kind of whole nesting type structure outer rotor torque motor and has directly been driven milling head, comprises being positioned at inner outer rotor torque motor stator and being positioned at the stator outside, with the torque motor rotor of yaw collar bush one; Also comprise the supporting mechanism that is positioned at inner stator support frame, coolant jacket one and additional pneumatic clamp band-type brake system.
Wherein, the coolant jacket set inside has a few font circulation cooling baths.The pneumatic clamp band-type brake system on the supporting mechanism of being installed in directly holds the outrigger shaft of oscillating spindle cover tightly.
Whole nesting type structure outer rotor torque motor with reference to figure 2 explanation the utility model is directly driven milling head; Comprise two outer rotor torque motor, yaw collar bush 7 and stator support frame 6; Said outer rotor torque motor comprises torque motor stator 1, torque motor rotor 2 and is attached to the outside stator coolant jacket 3 of said torque motor stator 1, and said torque motor stator 1, stator coolant jacket 3 and stator support frame 6 are whole nesting type structure.
In sum, in the utility model, yaw collar bush and torque motor rotor integrate, thereby avoid because the problem of the poor rigidity that causes of thread connection, have also reduced the volume of milling head simultaneously.And replace hydraulic contracting mechanism with the pneumatic clamp band-type brake system of the overhanging shaft type of yaw collar bush, and reduce manufacturing cost, improve response speed.
