Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described with reference to the drawings.
As shown in Figure 1, electric welding machine dust suction protective device, including protective cover 6, the protective cover 6 is opening down, and top is opened
There is a through hole, installation connector sleeve 2 in through hole, 2 top of connector sleeve is equipped with fixed running-on 1, and the fixation running-on 1 is used for will
Connector sleeve 2 is mounted on the welding gun of electric welding machine, and fixed running-on 1 can be the running-on with sealing ring, and be locked by bolt.
Welding gun is entered through connector sleeve 2 in protective cover 6；The opening connection telescopic cover cylinder of protective cover 6, described stretches
Contracting cover cylinder includes the expansion plate 10 of multiple arcs and fixed cylinder 8, and the expansion plate 10 of the multiple arcs is arranged vertically, and is surrounded
One cylindrical shape, the edge of adjacent expansion plate 10 can be provided with male and female groove, be mutually twisted, and opposite can slide.
The side wall of the fixed cylinder 8 is provided with the annular groove 9 of vertical direction, annular groove 9 it is opening down, it is described
Expansion plate 10 is mounted in annular groove 9, and expansion plate 10 slides up and down in annular groove 9, and right angle setting is gone back in annular groove 9
There are compression spring 7, the top of 7 lower end of compression spring connection expansion plate 10.
When welding nonplanar weldment, every piece of expansion plate 10 is touching weldment surface, in the effect of compression spring 7
Under power, 10 lower edge of expansion plate is close to face of weld, and height is different everywhere for face of weld, therefore every piece of expansion plate 10 is also stretched
Go out different length, each expansion plate 10 of holding is close to face of weld as far as possible.
Inlet scoop 4 is also provided on the protective cover 6, the inlet scoop 4 connects exhaust fan by pipeline 5.Welding gun into
Exhaust fan is opened when row welding and carries out exhausting, and the flue dust absorption in protective cover 6 is focused on.
10 lower edge of expansion plate is provided with flash item 11.Flash item 11 can improve 10 lower end of expansion plate and weldering
The leakproofness on part surface.
Can also protection vent hole be opened up according to welding requirements on protective cover 6, protection gas is passed through into protective cover.
It is additionally provided with rubber sleave 3 in the connector sleeve 2, the rubber sleave 3 is inverted taper type structure, upper end
Larger edge of opening is fixed on 2 inner wall of connector sleeve, and the smaller opening in lower end is symmetrically provided with multiple expansion joints, and described is flexible
Side wall of the seam along rubber sleave 3 is directed toward the larger opening in upper end.Welding gun is stretched into from the smaller opening of rubber sleave 3, rubber skin
The smaller opening diameter of set 3 is less than the outer diameter of welding gun, and expansion joint can provide certain elasticity so that rubber sleave 3 is close to
On welding gun, while welding gun can also flexible rotating.
