Embodiment two
A kind of a kind of step of the control method for Turret Type CNC Punch Press special clutch that embodiments of the invention two are provided
Rapid figure is as shown in figure 9, above-mentioned clutch is identical with the clutch configuration in embodiment one, therefore is not repeated here, this method bag
Include following steps：
Step S110：When needing to be rotated drive shaft 34, start motor 29, the motor 29 is carried out just
Turn, rotated so as to drive with the push arm structure that motor 29 is connected by attachment structure, when push arm structure for eccentric shaft 15 or
During person's camshaft, under the driving effect of motor 29, push arm structure starts to rotate；When push arm mechanism is screw-nut structure,
Under the driving effect of motor 29, screw structure starts to rotate, and forces nut along the moved axially forward of the leading screw.
Step S120：When push arm structure is eccentric shaft 15 or camshaft, because excircle is arrived in the axle center of push arm structure
Length is uneven along each radial distribution, therefore push arm structure passes through and rotated so that at its outer circumference surface contact with pressing plate 14 and
The distance in its axle center constantly becomes big, so as to promote pressing plate 14 to move axially forward, it is, of course, also possible to the push arm structure with
At least one cylinder roller bearing is set on the outer circumference surface that pressing plate 14 is contacted, pressure is promoted forward so as to reduce push arm structure
The frictional force that plate 14 is produced；When push arm structure be screw-nut body when, leading screw by rotate make nut on leading screw vertically
Move forward.
So as to which pressing plate 14 is moved axially forward caused by the thrust of push arm structure, and then push rod fixed disk 19 is promoted to drive
Push rod 6 holds movement axially forward, because being connected between pressing plate 14 and push rod fixed disk 19 by thrust ball bearing, so in pressing plate
Push rod fixed disk 19 can be arranged on its internal drive shaft 34 and drive while 14 forward movements promote push rod fixed disk 19
It can still rotate；Because the front end of push rod 6 is contacted at the rear end face of internal tooth casing 2, therefore push rod 6 moves forward and promotes interior
Tooth set 2 is slided axially forward, and then is made between multiple external tooth friction plates of the first friction plate group 5 and multiple internal toothed friction plates
Gap constantly reduces, and finally fits.
Step S130：Because flywheel is connected with clutch housing 4, and clutch housing 4 is driven by flywheel and rotated, because
The external tooth friction plate that the multiple and clutch tooth of this first friction plate group 5 is engaged is driven by clutch housing 4 to be rotated, first
After friction plate group 5 is fitted, multiple external tooth friction plates of the first friction plate group 5 are that the multiple internal tooths for driving the first friction plate group 5 rub
Pad is rotated, so that multiple internal toothed friction plates of the first friction plate drive gear bush 1 to be rotated, and then realizes flywheel
Drive shaft 34 is driven to rotate.
A kind of the step of another control method of Turret Type CNC Punch Press special clutch of present invention offer, schemes such as
Shown in Figure 10, including the steps：
Step S210：When the drive shaft 34 needs to stop, controlled motor 29 is inverted, and the second pushing mechanism of driving carries out anti-
Turn, so that the second pushing mechanism is moved to the direction away from internal tooth casing 2；When push arm structure is eccentric shaft 15 or camshaft,
Because the axle center of push arm structure is uneven to the length of excircle along each radial distribution, therefore under the driving effect of motor 29,
Push arm structure causes the distance at its outer circumference surface contacted with pressing plate 14 with its axle center to be continuously getting smaller and smaller by rotation, so as to
Direction away from pressing plate 14 is moved, it is, of course, also possible to be set at least on the outer circumference surface that the push arm structure is contacted with pressing plate 14
One cylinder roller bearing is to reduce the friction between push arm structure and pressing plate 14；When push arm structure is screw-nut structure,
Under the driving effect of motor 29, leading screw, which rotate, makes nut be moved vertically to the direction away from pressing plate 14；So as to push arm
Structure cancels the thrust to pressing plate 14.
Step S220：After the rear end face of pressing plate 14 loses thrust, i.e., push rod 6 and push rod fixed disk 19 also lose and pushed away simultaneously
Power, the first pushing mechanism (i.e. groups of springs) for being arranged on the front side of internal tooth casing 2 starts effect, promotes internal tooth casing 2 to slide axially rearward
It is dynamic, so that the gap between the multiple external tooth friction plates and multiple internal toothed friction plates of the second friction plate group 8 of promotion of internal tooth casing 2 is not
It is disconnected to diminish, finally it is fitted, separated while the first friction plate group 5 loses after power of slippaging.
Step S230：Because brake is fixedly installed on the static housing 11 of clutch, therefore brake casing 10 is protected
Transfixion is held, after the second friction plate group 8 is fitted, due to the braking of the multiple and brake casing 10 of the second friction plate group 8
The external tooth friction plate of tooth engagement stops not turning all the time, so that multiple external tooth friction plates of the second friction plate group 8 drive and external tooth cover
The internal toothed friction plate of 35 connections stops operating, and the internal toothed friction plate and external tooth friction plate of the first friction plate group 5 depart from, and then
The drive shaft 34 fixed with external tooth cover 35 stops operating, so as to complete the stopping of drive shaft 34.
In summary, the embodiment of the present invention is divided by the way that internal tooth is set on gear bush, and at the two ends of internal tooth casing
First friction plate group and the second friction plate group are not set, when making internal tooth casing push away the second friction plate group by the first thrust structure
Close, while separating the first friction plate group, drive shaft is in halted state；The push arm knot of the second thrust structure is driven by motor
Structure so as to make internal tooth casing that the first friction plate group is slippaged indirectly, while separating the second friction plate group, realize that flywheel drives drive
Moving axis is rotated, so that Turret Type CNC Punch Press clutch thoroughly departs from hydraulic control, realization passes through simple mechanical structure pair
Clutch is controlled, so as to reduce the maintenance cost and production cost of clutch, and improves the reaction speed of clutch.
