Specific 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 the embodiment of whole.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. 3 is referred to, in the embodiment of the present invention, a kind of project-welding nut pressurizes arm assembly, including it is column 1, guide plate 2, solid
Determine block 3, soft copper band 4, rolling bearing 5, insulation board A6, e axle supporting seat 7, rotating shaft 8, oil-free bushing 9, axle limiting plate 10, arm
11st, insulation board B12, lower conductive platform 13, upper conductive platform 14 and bottom electrode 15, the column 1 is vertically connected to by bolt
Upper surface one end of lower conductive platform 13, with one side of guide plate 2 top side of column 1 is fixedly connected on using bolt and pin
Insulation board B12 is set between 13 on face, column 1 and lower conductive platform, and the upper surface other end of the lower conductive platform 13 is installed
Bottom electrode 15.
The lower surface front end of the upper conductive platform 14 is bolted to connection e axle supporting seat 7, the He of upper conductive platform 14
Fixed insulation board A6 between e axle supporting seat 7, e axle supporting seat 7 connects the rotating shaft 8 on arm 11 by oil-free bushing 9, so that
Obtaining arm 11 can rotate, and the side of the arm 11 is fixedly connected fixed block 3, and the side of fixed block 3 passes through rolling bearing 5
Rolling is connected in the gathering sill opened up on guide plate 2
The arm 11 is provided with two oil-free bushings 9 by interference fits, and coordinates with the gap of rotating shaft 8, and both can be with
Relatively rotate.
The two ends of the e axle supporting seat 7 are provided with axle limiting plate 10, and by axle limiting plate 10 movement of the both sides of rotating shaft 8 is limited
With relative rotation.
With 4 one end, soft copper connects arm 11 to the connection soft copper of upper conductive platform 14 with 4 other end.
The present invention operation principle be：
Clamping workpiece and nut are finished, and arm 11 and its connector are pushed in moving process with upper conductive platform 14, are subject to
The gathering sill of guide plate 2 is limited, and arm 11 starts 8 to rotate up to the surface position of bottom electrode 15 around the shaft while moving downward
Put, then move downward clamp nut and welded.Welding current connects arm 11 and does not receive arm 11 by soft copper band 4
Motion affects.Column 1 passes through insulation board with lower conductive platform 13（12）Isolation, it is to avoid welding circuit shunt influence welding effect.
Usually in the case of arm is opened, this pressurization arm assembly has the sufficient space being capable of quick-clamping workpiece.By resistance
Welding machine pressurized cylinder action, arm 11 efficiently and effectively workpiece pressing nut and can be positioned.Welding current is led from above
Level platform 14 is delivered to arm 11 by soft copper band 4, then is delivered to workpiece nut, passes next to bottom electrode 15 and constitutes electricity
Flow back to road and realize welding.
The arm is guided by gathering sill, changes the state that can only move up and down of arm, be allowed to avoid with
Interference and effective increase piece installing space between workpiece；And the arm need not increase extra power, therefore this
Invention by improved structure, efficiently against the deficiency of prior art.
With 5KG weight, 500mm length, for the workpiece of a nut, using existing improved structure, work piece production
