Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described.Following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of architectural prefab keel automatic spot welding equipment, comprises body 3, top electrode unit 5, bottom electrode unit 6 and polishing head 4.
The innovation of this automatic spot welding equipment is: top electrode unit is row's top electrode, and top electrode unit controls lifting by polishing head.This row top electrode comprises 4-10 top electrode, all connects a polishing head.Be 6 top electrodes in the present embodiment.
Bottom electrode unit arranges bottom electrode 11 by bottom electrode axle 9, at least two and electrode axis driver element 7 is formed, on bottom electrode axle certain angular interval be fixedly mounted with described at least two row bottom electrodes, bottom electrode axle is undertaken determining angular turn by electrode axis drive unit drives, makes bottom electrode relative with top electrode.In the present embodiment, bottom electrode is 6 corresponding with top electrode.Upper and lower electrode all adopts the manufacture of chromium zirconium copper product, the feature such as when having high temperature, hardness is high, electric conductivity is good.Electrode axis driver element is by motor-driven sheave driving mechanism 19.
In the present embodiment, bottom electrode unit is arranged with four of 90 degree of intervals row's bottom electrodes.Bottom electrode is fixedly mounted with by connecting plate and bottom electrode axle.The top of bottom electrode is semicircular electrode header structure, has the annular groove 12 for setting-in keel shoe, facilitate keel shoe to locate at the top of this semicircular electrode head, can ensure keel shoe and the good contact condition of connection bracket simultaneously.On the often row bottom electrode of bottom electrode unit, equal interval is furnished with keel connection bracket gripper shoe 10, and this gripper shoe top is shaped with semi-circular recesses, for placing keel connection bracket.
Also comprise a self-feeding unit 8, this self-feeding cellular installation is in the frame of bottom electrode unit bottom, this self-feeding unit is made up of longitudinal rail 13, lift drive mechanism, supporting plate 14, horizontal guide rail 16, horizontal drive mechanism and stock chest 15, and supporting plate to be arranged on longitudinal rail and to be connected with lift drive mechanism; Arrange horizontal guide rail between stock chest and supporting plate, stock chest is connected with horizontal drive mechanism; Be shaped with keel shoe locating slot 17 at the inner surface interval of stock chest, consider to reduce stock chest height and alleviate material-storing box deadweight, each bottom portion of groove opens hole 18.This keel shoe locating slot is corresponding with the position of each electrode in described bottom electrode.Lift drive mechanism, horizontal drive mechanism all adopt air cylinder driven mode.
The course of work of this automatic spot welding equipment is:
This automatic spot welding equipment is for welding building prefabrication keel, and these building prefabrication keel are made up of connection bracket 1 and keel 2.During welding, control stock chest protruding, be positioned over by six keel shoes in the made keel shoe locating slot of blow tank, stock chest is retracted, and supporting plate drives stock chest rise and be loaded in the made annular groove of bottom electrode by six keel shoe locator cards.Supporting plate drives stock chest to decline, and completes a feeding.
