The operation principle of permanent magnetism axle core component：
Stator side is passed through three-phase symmetrical electric current, because threephase stator differs 120 ° on locus, so threephase stator
Electric current produces rotating excitation field in space, is moved in p-m rotor rotating excitation field by electromagnetic force.
The operation principle of cylinder assembly：
When main shaft unloads knife, compressed gas is passed through cylinder top cover by the first air flue, and cylinder top cover receives the air pressure of compressed gas
Move down, promote the top surface of first piston to move down, first piston promotes second piston to move down, and second piston is promoted under connecting rod
To move, connecting rod applies pressure to pull bar, and pull bar increases disk spring deformation under stress, while pull bar drives slide cores to move down,
The position that pulling claw contacts with slide cores is gradually distance from slide cores along slope upward sliding is slided, and pulling claw, which shrinks, unclamps central water outlet knife
Handle, and central water outlet handle of a knife is ejected, knife action is unloaded in completion.
During main spindle broach, the compressed air of the first air flue is closed, and the disk spring of deformation is not under by cylinder pressure condition
Recover elastic deformation, pull bar moves up resets, and pull bar moves up drive slide cores and moved up, when the position that pulling claw contacts with slide cores is along cunning
Dynamic slope gradually downward when, pulling claw opens, meanwhile, when pulling claw and central water outlet handle of a knife clamping, tense central water outlet handle of a knife and complete drawing
Knife acts.
When main shaft resets, reset gas is passed through to the second air flue, second piston be pushed into upwards in the case where resetting gas effect with
Connecting rod flange separates, then the upper surface of first piston contacts with cylinder top cover, avoids main shaft from producing friction when rotating, and completes multiple
Position action.
First piston built in cylinder assembly and second piston, two layers of distribution, while leave the company of connecting rod and swivel joint
Connect position；Cylinder engine saves installing space, rear-end of spindle is overhang short, and compact-sized, rigidity is big, and stability is strong.
The operation principle of central water outlet component：
In high-speed rotation, swivel joint is fixed on cylinder top by stator and screw and covered main shaft.Coolant
Flowed into from the upper end water inlet at swivel joint center, the first sealing ring built in swivel joint is sealed, ensured in main shaft height
Coolant will not be leaked in main shaft in speed rotation, damage main shaft.Coolant is flowed into pull bar by connecting rod, and connecting rod is with drawing
Bar is spirally connected, and the sealing of the second sealing ring, so as to ensure that cooling water circulates vertically, and is unlikely to leak to inside shaft core.Pull bar with
Slide cores are spirally connected, and the sealing of the 3rd sealing ring, jackscrew is locking, ensure that coolant stablizes output vertically when main shaft runs at high speed.
Main shaft is coordinated to use Special central water outlet handle of a knife.Is set in the slide cores being engaged with central water outlet handle of a knife
Four sealing rings are sealed, and positioning gland positions to the 4th sealing ring, ensure that central water outlet will not be leaked to inside shaft core.Not from
The unnecessary coolant of central water outlet handle of a knife discharge can flow out from spout hole.By the overall structure of contact seal, ensure main shaft
The stability and high efficiency output of central water outlet cooling system in high-speed rotation.
The hydraulic pressure that swivel joint can be born has a clear superiority relative to contactless joint, there is very high use value.
Connecting rod is precisely controlled principle with swivel joint axiality：
Because swivel joint requires higher to coupled connector axiality.So connection being connected with swivel joint
Bar assembling is most important to realizing for alignment of shafts outlet system with machining accuracy.
Connecting rod is connected through a screw thread with pull bar.There are the first snap ring and the second snap ring at connecting rod and pull bar cooperation, and the
The diameter of one snap ring is more than the diameter of the second snap ring.Connecting rod front end external thread section screws in pull bar first, and the first snap ring is polished rod,
Nature centering can be carried out, while can be corrected, makes to ensure good axiality between connecting rod and pull bar, is positioned by end face, the
Two snap rings are embedded in neck, are stably connected with the height of bar flange, ensure that the reading of sensor is accurate, so sensor sensing unloads
Knife, broaching tool stable output signal.
Embodiment 2
This embodiment is characterized in that：Reference picture 4, glue-line 34 is provided between the lower surface of p-m rotor 31 and shaft core 33；
Gap 35 is provided between the between centers set 32 and p-m rotor 31；Remaining structure and features is same as Example 1.
, can be by iron adsorption in shaft core because p-m rotor has magnetic, especially embedding plant between centers set and p-m rotor
Gap in, it is difficult to remove.If iron filings can not be removed totally, rotation can throw away iron filings main shaft at a high speed, cause electro spindle
Service life shortens.To solve this problem, it is arranged on during design after the lower surface gluing of p-m rotor in shaft core, forms glue
Layer, it is therefore prevented that the embedding Tibetan of iron filings；1mm gaps are designed with p-m rotor and between centers inner room, do not have embedding Tibetan in following process
Iron filings risk, solve the problems, such as that permanent magnetism axle core component hides bits.
For those skilled in the art, technical scheme that can be as described above and design, make other each
Kind is corresponding to be changed and deforms, and all these change and deformed the protection model that should all belong to the claims in the present invention
Within enclosing.
