Degree also just and then the quantity of cutter and determine.
The operation principle of brake positioning formula knife tower 6 of the present invention is described in further detail with reference to Fig. 1.
In course of normal operation, rotation clutch tooth 3 is dynamic, and the clutch tooth 4 that stretches is static state, rotation clutch tooth 3 and flexible
Clutch tooth 4 is in released state.Pipeline 11 is entered by oil inlet 10 by hydraulic oil caused by compression pump.Now, in high pressure
Under the pressure effect of oil, brake block 8 is realized with rotor 9 and is interference fitted, so as to realize locking of the brake block 8 to rotor 9, because
This, the knife tower enters normal work dress state.
, can be by adjusting the pressure of hydraulic oil, to adjust the brake block 8 to rotor 9 in normal work engineering
Locking power, generally, as long as the oil pressure of hydraulic oil disclosure satisfy that lathe processing when rigidity.
In brake positioning formula knife tower 6 of the present invention, when lathe receives the setting of external force collision or servo motor 1
Formula the fortuitous event such as makes a fault when occurring, due to rotation clutch tooth 3 and flexible clutch tooth 4 in the course of the work be in point
From state, now the center height of brake positioning formula knife tower 6 can produce corresponding displacement after being impacted, and produce the mistake of displacement
Journey can lay down the impact that moment brings.So external force will not to the lathes such as rotation clutch tooth 3, knife tower axle 2 and axis hole its
Any destruction occurs by parts in he, and relative to knife tower of the prior art, knife tower of the present invention can greatly reduce car
The loss that the practice of bed in the course of the work is brought, so as to reduce the use cost of lathe and production efficiency.
Next the exchanging knives process of brake positioning formula knife tower 6 of the present invention is further described according to Fig. 1.
The setting formula that external force collision or servo motor 1 are received when lathe makes a fault etc. that there occurs lead fortuitous event
When causing tool damage so as to need tool changing.
Cancel and hydraulic oil is injected to pipeline 11, now the knife tower axle 2 can easily rotate.
Because servo motor has Memorability, therefore servo motor 1 can rotate to corresponding set angle with moving knife tower axle 2
Degree, when.The clutch tooth 4 that now stretches is bonded under the promotion of hydraulic cylinder with rotation clutch tooth 3, using rotation clutch tooth 3 and is stretched
Clutch tooth 4 is further to improve the precision of orientation angle.Such as if what is installed on cutter head structure 13 is 12 cutters,
The cutter placed in so each cutter spacing is separated by 30 degree.
Due to the Memorability of servo motor 1, thus in theory servo motor 1 can be rotated to moving knife tower axle 2 it is adjacent
At 30 degree, but because servo motor 1 further relates to the driving members such as belt during band moving knife tower axle 2, cause knife tower axle 2 most
The precision of the whole anglec of rotation has declined.Such as according to setting, knife tower axle 2 needs 20 degree of rotation to get to set accordingly
Determine angle, but because servo motor between knife tower axle 2 has drive gap, running accuracy is affected, it is possible that only revolving
Turn 19.9 degree and just stopped not turning, rotation clutch tooth 3 has also correspondingly only turned 19.9 degree.
And because the angle for the clutch tooth 4 that stretches is constant, it can only stretch and can not rotate, so flexible clutch tooth 4
Angle be still the accurate angle originally needed.
Now, the flexible clutch tooth 4 of Hydraulic Cylinder is bonded with rotation clutch tooth 3 and is corrected to the rotation clutch tooth 3
Due set angle.
When PLC detect flexible clutch tooth 4 and rotation clutch tooth 3 be bonded signal after, by high pressure caused by high-pressure pump
For oil by the input channel 11 of oil inlet 10, brake block 8 and rotor 9 can be produced interference fit by the hydraulic oil of input, from
And realize locking.
After PLC detects that the pressure of hydraulic oil reaches setting pressure, also need to set time delay by one section again, it
Afterwards just can control cylinder so that rotation clutch tooth 3 and flexible clutch tooth 4 become released state.Now, the brake positioning formula
Knife tower 6 enters normal working condition, and lathe realizes normal process process again.
In the whole exchanging knives process of brake positioning formula knife tower 6 of the present invention, speed simple in construction is fast.After coordinating again
The clutch tooth at end carrys out orientation angle, and the theory orientation angle in exchanging knives process can be as accurate as ± 0.000015 degree, operating radius
In 250mm ± 0.003mm, had little to no effect at this point for processing diameter, machining accuracy can equally reach ± 0.003 degree.
The present invention compared with the existing technology, has advantages below and beneficial effect:
1st, the present invention is due to there was only rotor, brake block and fixed body, and brake block is to be fixedly connected with knot with fixed body
Structure, without increasing seal, no matter in sealing property or cost control, having greatly improves.
2nd, the present invention substitutes alone clutch tooth by using brake, can when lathe is collided knife tower center height
Substantial amounts of displacement is produced after receiving impact, the impact that moment brings is laid down, so as to protect the miscellaneous part of lathe to be damaged.
3rd, formula knife tower 6 is positioned using the impaired brake of the present invention, when a collision between vehicles occurs, knife tower is exchanged once again
Precision can just be recovered automatically, without maintenance, because the angle that knife tower rotates is absolute coordinate, the rotation clutch tooth by servo motor
And flexible clutch tooth control, precision is accurate.
In other words, 6 difference maximum with knife tower of the prior art of brake positioning formula knife tower of the present invention is exactly to use
The mode of brake instead of positioning tooth, and knife tower parts of the prior art are relatively more, have rotor, brake block, seal with
And fixed body, and the present invention only has rotor 9 and fixed body 7, the fixed body 7 is to be fixedly connected not sealing with brake block 8
Part.The inwall for being passed through fixed body 7 after hydraulic oil produces small expansion so as to realize brake function.
The sharpest edges for substituting positioning tooth with the mode of brake are the positioning formula knife towers that braked when lathe is collided
6 center height can produce substantial amounts of displacement after receiving impact, lay down the impact that moment brings, so as to protect lathe other
Part is damaged.
Due to the memory function that servo motor 1 possesses, at this moment only need again to exchange knife tower and once can just recover automatically
Precision is not required to repair.This can not only save time, the efficiency for improving production and can greatly reduce the loss that error is brought.
Above-mentioned introduction is that the above-mentioned brake positioning formula knife tower 6 of the present invention is used into hub to stop, and the active area that hub is stopped compares
Greatly, so braking strength is big, it is adapted to heavy cutting processing, accordingly, the volume of the brake positioning formula knife tower 6 is also bigger.
