Hold-down mechanism can realize opening and closing, use and repair more convenient.
Brief description of the drawings
Fig. 1 is existing internal welding machine wire feeder structural representation；
Fig. 2 is internal welding machine wire feeder structural representation provided in an embodiment of the present invention.
Embodiment
With reference to the accompanying drawings and examples, technical solution of the present invention is further described.
Referring to Fig. 2, the embodiments of the invention provide a kind of internal welding machine wire feeder, including insulating base 1, pressing plate 21, pressure
Plate 22, hold-down mechanism 3, contact roller 4, wire feed rolls 9, locking pin 5 and shell fragment 6.Wherein, one end of hold-down mechanism 3 passes through interior hexagonal
Fillister head screw is connected with shell fragment 6；Strip through hole 61 is provided with shell fragment 6；The other end of hold-down mechanism 3 passes through thrust axis
Hold the one end being fixed on locking pin 5 on insulating base 1；Contact roller 4 is embedded in hold-down mechanism 3 by bearing and bearing pin；
Wire feed rolls 9 is arranged in the arc groove on insulating base 1, and positioned between pressing plate 21 and pressing plate 22；Pressing plate 21 and pressing plate
22 are fixed on insulating base 1 by the way that hexagon socket cap head screw is parallel；Welding wire delivery outlet 211 is provided with pressing plate 21,
Welding wire input hole 221 is provided with pressing plate 22；The other end on insulating base 1 is provided with the pivot pin 7 that can be engaged with shell fragment 6,
Being provided opposite on arc convex 8, pivot pin 7 of pivot pin 7 is provided with adjustable hexagon socket cap head screw 71, and screw 71 is located at
The top of arc convex 8；Welding wire input hole 221 connects welding wire protective case.
Referring to Fig. 2, the internal welding machine wire feeder of the embodiment of the present invention drives wire feed rolls to rotate and sent to realize by motor
Thread, its operation principle is：First the groove 11 by welding wire protective case along the side of arc convex 8 inserts welding wire input hole 221, then
Welding wire is stretched into welding wire protective case, the welding wire stretched out from welding wire protective case via wire feed rolls 9 delivers to welding wire delivery outlet 211；So
Afterwards, shell fragment 6 is pressed onto on arc convex 8 manually, and shell fragment 6 is locked by screw 71 and strip through hole 61, make weldering
Silk, which is clamped between contact roller 4 and wire feed rolls 9, to be passed through；Motor driving wire feed rolls 9 is rotated, and wire feed rolls 9 drives contact roller 4 to rotate,
Welding wire is moved under the collective effect of wire feed rolls 9 and contact roller 4, and is delivered to welding gun by welding wire delivery outlet 211.In reality
In, welding wire protective case can not only protect welding wire, but also can make to keep insulation between welding wire and insulating base；Pass through
