During machine operation, the drive shaft casing 9 of main spindle box revolution synchronous pulley 3 returns with endoporus of the rotation inner sleeve 4 in slide plate 5
Turn, main shaft power inputs synchronous pulley 2, power input shaft 1, bevel gear 8 etc. by power and is delivered to main axle unit 18.Tool changeover
When, system sends signal, and booster 22 works, and pressure oil enters slide plate 5-- rotations inner sleeve 4 by pressure oil pipe II and pipe joint leads
Flow annular groove -- the rotation vertical holes of the inner sleeve 4 -- vertical holes of main spindle box body 9 -- upright opening of main spindle box body 9 -- 22-oil hydraulic cylinder of pressure oil pipe
11 cavity of resorptions.The transmission of compressed air and the transmission of pressure oil are essentially identical, and gas is entered by source of the gas input pipe 19 and pipe joint to be slided
Plate 5-- rotates the water conservancy diversion annular groove of inner sleeve 4, and -- -- vertical holes of main spindle box body 9 -- upright opening of main spindle box body 9 -- is even for the rotation vertical holes of inner sleeve 4
Trachea 20, finally enter oil pressure cylinder end cap 14.
By the way that with upper pathway, in main spindle box body 9 and main shaft composite revolving, pressure oil and compressed air are passed by stationary outer
It is sent in the oil hydraulic cylinder of revolution, realizes biography of the fluid media (medium)s such as hydraulic oil, compressed air between the part that composite revolving moves
It is defeated.
2nd content of the invention embodiment
Such as accompanying drawing 1,2, pressurized cylinder is divided into booster 22 and the two parts of oil hydraulic cylinder 11, booster 22 is fixed on slide plate 5,
Oil hydraulic cylinder 11 is installed on the main spindle box body 9 of revolution, and hydraulic cylinder piston rod 12, adjusting bolt 15, main shaft pull bar 16 keep coaxial.
After system sends Tool changeover signal, pressure oil caused by booster 22 passes through path transmission mentioned above to oil hydraulic cylinder 11
Cavity of resorption, in the presence of pressure oil, hydraulic cylinder piston rod 12 drives adjusting bolt 15 to promote main shaft pull bar 16, overcomes butterfly spring
Pulling force broaching tool pawl is unclamped blind rivet, cutter is totally released in spindle taper hole, and realization is forged a knife function, and cutter is carried out by manipulator
Exchange.
After new cutter is put into spindle taper hole by manipulator, system sends signal, magnetic valve commutation, and the piston of booster 22 returns
Journey, oil circuit pressure declines, in the presence of back-moving spring 13, the back resetting of hydraulic cylinder piston rod 12, and fluid backflow.Main shaft pull bar
16 tense blind rivet by the active force control broaching tool pawl of butterfly spring, new cutter is positioned and is clamped in spindle taper hole.Can be with
Find out, although oil hydraulic cylinder 11 turns round with main spindle box body 9, the method that is separated with oil hydraulic cylinder using above booster, and combine the
One content of the invention can smoothly complete Tool changeover action.
3rd content of the invention embodiment
As shown in figure 1, adjusting bolt 15 is axially machined with outlet endoporus, radially go out in its end and axially vertical be machined with
Stomata.Adjusting bolt 15 is fixed in the internal thread hole of hydraulic cylinder piston rod 12, and footpath is machined with the slide opening bottom of internal thread hole
To gas port.The top of oil pressure cylinder end cap 14 is machined with compressed air entrance hole, the annular diversion trench phase with oil pressure cylinder end cap 14
Insertion.
In cutter in the state that spindle taper hole positions and clamps, hydraulic cylinder piston rod 12 is in the presence of back-moving spring 13
Backhaul is resetted, now keeps fixing between the annular diversion trench of oil pressure cylinder end cap 14 and the radial direction gas port of hydraulic cylinder piston rod 12
Distance.Such as accompanying drawing 1,2, the transmission of compressed air enters the slide plate 5-- rotation guide rings of inner sleeve 4 by source of the gas input pipe 19 and pipe joint
-- -- vertical holes of main spindle box body 9 -- upright opening of main spindle box body 9 -- connects tracheae 20-oil pressure cylinder end cap to the rotation vertical holes of inner sleeve 4 to groove
14 endoporus water conservancy diversion annular grooves, because being kept between the annular diversion trench of oil pressure cylinder end cap 14 and the radial direction gas port of hydraulic cylinder piston rod 12
Fixed range, the air admission hole of oil pressure cylinder end cap 14 will not dock with the radial direction gas port of hydraulic cylinder piston rod 12, and between holes
There is O-ring seal to be isolated, compressed air will not enter the endoporus of hydraulic cylinder piston rod 12, and now compressed air is sealed, gas circuit
Pressure will not decline, and pressure normal signal is fed back to system by baroceptor 18, take tool mechanical hand not work.
During Tool changeover, it is necessary to assure handle of a knife is totally released when manipulator takes cutter away.When needing tool changing, booster
23 pressure oils are injected into the cavity of resorption of oil hydraulic cylinder 11, and hydraulic cylinder piston rod 12 promotes main shaft pull bar 16.Hydraulic cylinder piston rod 12 stretched out
The distance between Cheng Zhong, the air admission hole of oil pressure cylinder end cap 14 and radial direction gas port of hydraulic cylinder piston rod 12 are gradually shortened, oil pressure
After cylinder piston rod 12 reaches design runlength, main shaft pull bar 16 is promoted to be totally released cutter.In end of travel, oil pressure cylinder end cap 14
Air admission hole docks with the radial direction gas port of hydraulic cylinder piston rod 12, compressed gas by oil pressure cylinder end cap 14 air admission hole -- oil hydraulic cylinder
The radial hole of radial direction gas port -- endoporus of adjusting bolt 15 -- adjusting bolt 15 of piston rod 12 and discharge, airline pressure drops therewith
Low, baroceptor 18 acts, and oil hydraulic cylinder signal in place of forging a knife is fed back to system, system control machine tool hand takes cutter away.
