Technical field
The utility model is related to field of machinery automation technology, refers in particular to a kind of for the clear gun system of welding robot
Cut silk device.
Background technology
With the fast development of industry, welding product is more and more appeared in our life, people's living standard
Constantly improve, solder technology is also more and more important.
Silk device is cut in existing clear gun system, volume is big, complex structure, part processing and assembling are more complicated, and it is cut
Cutting edge is common " one " font blade, and, because clipped position is fixed, blade abrasion is very fast in use, makes for a this mode of cutting
It is shorter with the life-span;And two blade hardly possible in same level, cause blade misplace cut silk so that welding wire end cut is not concordant,
Particularly after edge wear, effect is worse.
Utility model content
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide a kind of for welding the utility model
The clear gun system of welding robot cuts silk device, and it has simple structure, feature esy to use, safe and reliable.
To achieve the above object, the utility model is using following technical scheme:
It is a kind of to cut silk device for the clear gun system of welding robot, include support, drive mechanism, annular cutting blade,
Annular ledger-plate and controlling organization;There is a passage on the support, wire feed hole is provided with support, wire feed hole connection is logical
Road;The drive mechanism is arranged on support, and drive mechanism has a guide rod;The annular cutting blade and annular ledger-plate may be contained within
In passage, annular cutting blade is rotatably installed on the front end of guide rod, and guide rod drives annular cutting blade to move axially back and forth, annular
Cutting blade and annular ledger-plate are opposite to each other and are coaxially disposed with guide rod, and foregoing wire feed hole position is in annular cutting blade and annular stationary knife
Between piece;The controlling organization connects drive mechanism and controls drive mechanism to work.
Used as a kind of preferred scheme, the drive mechanism is cylinder.
Used as a kind of preferred scheme, the controlling organization includes air pump, solenoid directional control valve and controller;The air pump is connected
Solenoid directional control valve, solenoid directional control valve connection cylinder, controller connection solenoid directional control valve simultaneously controls gas circuit to switch.
As a kind of preferred scheme, it is installed on the outer end of support the annular ledger-plate replaceable.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme understands:
Annular cutting blade and annular ledger-plate contact cut welding wire are driven by using drive device, because of annular cutting blade circle
Circumferential direction position is not fixed, and when at work axially movable, can at random be rotated around guide rod axle center so that contacted every time when cutting thread
Blade edge position it is different, realize the cutting edge uniform wear of whole circle;Conveniently replaced installation site and continue after annular stationary knife pad wear
Use, extend blade service life;The utility model simple structure, install and it is easy to maintenance, improve service life and cut
Silk process is more steady reliable.
More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings
The utility model is described in detail.

Specific embodiment
Refer to shown in Fig. 1, that show the concrete structure of the preferred embodiment of the utility model, include support
10th, drive mechanism 20, annular cutting blade 30, annular ledger-plate 40 and controlling organization 50.
There is a passage 101 on the support 10, wire feed hole 102 is provided with support 10, the communicating passage of wire feed hole 102;
The drive mechanism 20 is arranged on support 10, and drive mechanism 20 has a guide rod 21, and in the present embodiment, drive mechanism 20 is gas
Cylinder.
The annular cutting blade 30 and annular ledger-plate 40 be may be contained within passage 101, and annular cutting blade 30 is rotationally pacified
Front end loaded on guide rod 21, guide rod 21 drives annular cutting blade 30 to move axially back and forth, annular cutting blade 30 and annular ledger-plate
40 are opposite to each other and are coaxially disposed with guide rod 21, are installed on the outer end of support 10 replaceable of annular ledger-plate 40;Foregoing wire feed
Hole 102 is located between annular cutting blade 30 and annular ledger-plate 40.
The controlling organization 50 connects drive mechanism 20 and controls drive mechanism 20 to work, and the controlling organization 50 includes air pump
51st, solenoid directional control valve 52 and controller 53;The air pump 51 connects solenoid directional control valve 52, and the solenoid directional control valve 52 connection cylinder should
Controller 53 connects solenoid directional control valve 52 and controls gas circuit to switch, and the output control signal of controller 53 input solenoid directional control valve 52 is controlled
End processed, realizes the switching of its gas circuit, so as to change the direction of motion of cylinder.
During work, the welding wire 70 that ignition tip 60 is sent out enters in passage 101 through wire feed hole 102;Controlling organization 50 is controlled
Drive mechanism 20 works, to change the direction of motion of drive mechanism 20;When the guide rod 21 of drive mechanism 20 travels forward, driving machine
Structure 20 drives annular cutting blade 30 near annular ledger-plate 40, and annular cutting blade 30 is contacted with annular ledger-plate 40 and cuts welding wire
70;When the guide rod 21 of drive mechanism 20 is moved backward, drive mechanism 20 drives annular cutting blade 30 away from annular ledger-plate 40, weldering
Silk 70 is through in the feeding passage 101 of wire feed hole 102;Because the circumferential locations of annular cutting blade 30 are not fixed, at work vertically
During motion, can at random be rotated around the axle center of guide rod 21 so that the blade edge position of contact every time is different when cutting thread, realize that whole circle cutting edge is equal
Even abrasion;The switching signal of controller 53 is input into solenoid directional control valve 52, makes cylinder drive annular cutting blade 30 to move backward and annular
Ledger-plate 40 is separated, and ignition tip 60 continues lower welding wire 70, and then cylinder is driving the annular cut-out of cutting blade 30 welding wire 70, so weight
It is multiple.
Design focal point of the present utility model is:
Annular cutting blade and annular ledger-plate contact cut welding wire are driven by using drive device, because of annular cutting blade circle
Circumferential direction position is not fixed, and when at work axially movable, can at random be rotated around guide rod axle center so that contacted every time when cutting thread
Blade edge position it is different, realize the cutting edge uniform wear of whole circle;Conveniently replaced installation site and continue after annular stationary knife pad wear
Use, extend blade service life;The utility model simple structure, install and it is easy to maintenance, improve service life and make
Obtain silk process more steady reliable.
The above, is only preferred embodiment of the present utility model, and not technical scope of the present utility model is made
Any limitation, therefore every any trickle amendment, equivalent change made to above example according to technical spirit of the present utility model
Change and modify, still fall within the range of technical solutions of the utility model.
