Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Embodiment
The utility model is described in further detail below, but the utility model is not limited to following examples.
As shown in figure 1, the straight buffers of welding servo wire feeder described in the utility model, installed in automatic welding
Between the torch body and wire feeder of robot (between i.e. forward and backward wire feeding motor), including the straight line being fixed in frame delays
The wire feed flexible pipe 7 for rush device housing 1, being arranged in straight buffers housing 1 and the control system company with automatic welding machine people
The displacement detecting component connect；The open rearward end of welding wire 11 from straight buffers housing 1 penetrates, before straight buffers housing 1
End opening is passed, and barrel assembly is entered after wire feed rolls, and wire feed flexible pipe 7 is set on welding wire 11, and the rear end of wire feed flexible pipe 7 is
Fixing end 8, the front end of wire feed flexible pipe 7 is free end 4, drives free end 4 to move when welding wire 11 moves, the installation of displacement detecting component
In the side of free end 4, so as to detect the amount of movement of free end 4 and send control system to by data connector 14, effectively protect
Demonstrate,prove that the speed that welding wire between welding robot welding gun push-and-pull silk and wire feeder moves is unbalanced, so as to reach welding wire movement
It is synchronous to require.
The displacement detecting component includes being fixed on the light-reflecting sheet 13 of free end by fixed cover 5 and being fixed on straight line
1 laser displacement sensor 12 in buffer case body, light-reflecting sheet 13 are arranged in parallel with the surface of emission of laser displacement sensor 12, swash
The output end of Optical displacement sensor 12 is connected with the control system of automatic welding machine people.
The free end of the wire feed flexible pipe is arranged in straight buffers housing 1 by linear bearing 6, so as to keep freely
4 straight lines are held to slide.Usually, linear bearing 6 is arranged in parallel with laser displacement sensor 12, and is put down with the axis of wire feed flexible pipe 7
OK.
The front opening of the straight buffers housing 1 is installed with wire leading pipe 3 by anchor tip 2, wire leading pipe 3
Axis is parallel with linear bearing, and the free end of wire feed flexible pipe is stretched into wire leading pipe, and free end and wire leading pipe are coaxially arranged.
The open rearward end of the straight buffers housing 1 is installed with into Threaded Connector Coupling 9 by anchor tip 10, and wire feed is soft
The rear end of pipe 7 is docked with entering Threaded Connector Coupling 9 and fixed.It is in fixed angle (example between the free end of the wire feed flexible pipe and fixing end
Such as 100~120 degree of angles) so that welding wire has a radian, can occur bending and deformation, and in seal wire tube axis direction
Stress is minimum when upper mobile.So as to provide a cushion space between former and later two wire feeding motors, two wire feeds are weakened
System can also utilize welding wire 11 cause the freedom of wire feed flexible pipe 7 to the pressure of wire feed flexible pipe 7 impulsive force of welding wire 11
End is subjected to displacement, and is easy to detect.
Operation principle of the present utility model is：
In welding process, wire feeding motor above according to the instruction of control system with the frequency of 70 times/second forwardly and rearwardly
Wire feed；Wire feeding motor below by the digital source of welding current according to system requirements according to constant wire feed rate wire feed forward, two
Wire feed system all realizes Digital Control.Laser displacement sensor is fixed in the straight buffers housing of metal plate making, light
Reflector plate is fixed on wire feed flexible pipe, and laser displacement sensor is located at behind light-reflecting sheet, light-reflecting sheet and laser displacement sensing
The distance between device surface of emission is fixed, and light-reflecting sheet and the laser displacement sensor surface of emission want keeping parallelism.
The laser that laser displacement sensor is sent is radiated on light-reflecting sheet and reflected, and passes through the transmitting of laser beam
The distance between laser displacement sensor and light-reflecting sheet are measured with receiving, if institute's ranging is set in advance from control system
Fixed distance, laser displacement sensor will provide analog signalses to control system.
In welding process, when former and later two wire feeding motor wires feed rate are equal, the light on wire feed flexible pipe is anti-
Penetrating piece will not act (being now normal weld).When the wire feed rate of above wire feeding motor is too fast relative to wire feeding motor below
When (also cry and rush silk or short circuit, short-circuit process is：Welding wire end is fused into molten drop, and molten drop forms short circuit with molten bath, when welding wire is quick-fried disconnected
With big electric current and splashing and produce substantial amounts of heat), now the free end of wire feed flexible pipe will be pulled along by welding wire, and light is anti-
Penetrating piece will move forward, and the increasing of the distance between laser displacement sensor and light-reflecting sheet, now laser displacement sensor is by mould
Intend signal and be transmitted to control system, after control system is connected to instruction, by the voltage of output, current control close to zero, and feed back to
Wire feeding motor above, it is desirable to its halt wire feed and make pumpback welding wire action, electric arc itself input heat process very
Just make welding wire and molten drop quick separating in short-term.
Under the control of totally digitilized closed loop, this transient mode is different from traditional droplet transfer mode completely.
In conventional welding process, when dry extension of electrode changes, the size of welding current can constantly change.And there is servo wire feed dress
The straight buffers put, dry extension of electrode only change wire feed rate when changing, will not cause the change of electric current, it is achieved thereby that
Consistent fusion penetration, plus the highly stable property of arc length, highly uniform weld appearance shaping can be reached.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this practicality is new
Type is not limited to above example, can also there is many variations.One of ordinary skill in the art can be from disclosed in the utility model
All deformations for directly exporting or associating in content, are considered as the scope of protection of the utility model.
