Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：A kind of tool changing device for reducing stroke, including cutter hub
20 and main body 100, the top of the main body 100 is provided with cutter hub 20, and the bottom of the cutter hub 20 is provided with the second cutter 201,
The right-hand member of the cutter hub 20 is provided with tool changing device 10, and the tool changing device 10 includes drive device 12 and tool striking device 40, institute
The stroke for stating tool striking device 40 is 8.5 millimeters, and the drive device 12 is ac motor, and the bottom of the drive device 12 is pacified
Equipped with tool change arm 11, the right-hand member of the drive device 12 sets tool striking device 40, the tool striking device 40 by rotary shaft 30 with
First cutter 200 is connected, and the top of the tool striking device 40 sets controller 60, and tool striking device 40 electrically connects with controller 60
Connect, the controller 60 is electrically connected with converter plant 50, the converter plant 50 is voltage frequency converter, and converter plant 50
The frequency sent is 60 hertz, and the converter plant 50 is electrically connected with drive device 12.
Controller 60 to control converter plant 50 export a first frequency for 60Hz to drive device 12, make drive device
12 are started, and tool change arm 11 can be to initial position toward button cutter position rotation, when tool change arm 11 rotates and close button cutter position
When, the control output second frequency of converter plant 50 of controller 60, its frequency is 20 to 30 hertz, is transmitted to drive device 12, due to
Second frequency is less than first frequency, then causes drive device 12 to carry out reduction of speed, and likes to keep operating, Zhi Houhuan in low-frequency range
Tool arm 11 carries out button knife action, so that the cutter of the clasp rotary shaft 30 of tool change arm 11, now tool change arm 11 does not stop completely, therefore energy
To about 20 kilograms of pulling force of cutter offer, pulling force is the zone of reasonableness born for rotary shaft 30, will not influence the knot of rotary shaft 30
Structure intensity and precision, then, wait tool striking device 40 to perform after stroke of forging a knife, tool change arm 11 is carried out action of drawing sword, and make
Its 180 degree is rotated to tool change position, the cutter of rotary shaft 30 and the cutter of cutter hub 20 is swapped action, is made to complete tool changing
After industry, the spinning reduction of tool change arm 11 when the driving tool change arm 11 of drive device 12 is close to button cutter position, is downconverted to 20 hertz to three
Ten hertz, and make the reduction of speed of drive device 12 and do not shut down, immediately write and perform follow-up button knife, draw sword and switching motion,
Restart after need not drive device 12 be stopped, virtually reducing the secondary time for carrying Noboru to for the national games turn again of drive device 12,
From 20 hertz to 30 hertz, Pa Noboru is to 60 hertz, contrast known structure need again from zero hertz of Pa Noboru to 60 hertz more
The saving time, therefore the time of tool changing operation actually can be substantially reduced, in addition, tool change arm 11 is in button cutter position, drive device 12
The slow-speed of revolution stage is still in, and the pulling force tool striking device 40 that 20 kilograms can be provided for the cutter in rotary shaft 30 is forged a knife
When, it is only necessary to the stroke of forging a knife that eight. five to eight point 7 millimeters of offer, i.e., the action of Pine knives can be completed, so that follow-up is drawn sword
Operation, and then the overall tool changing activity duration is effectively reduced, because drive device 12 is without weight after the brake stopping in operating
It is new to start, i.e., it can complete to drive the tool changing operation of tool change arm 11, can so substantially reduce the problem of the heating of drive device 12, keep away
Exempt to cause the risk of malformation because drive device 12 is generated heat, electronic component can be protected to be not susceptible to overload, and driving dress
Put 12 copper cash and be difficult exhaustion, so promote the Ti Noboru of drive device 12 its using life-span, the effect of reaching protection.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
