Detailed description of the invention
The structure that Figure of description illustrates, ratio, size etc., content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop in scope that technology contents that the utility model discloses can contain.Simultaneously, quote in this description as " on ", D score, "front", "rear", the term such as " centre ", also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As Fig. 1, shown in Fig. 3, a kind of Working piece positioning device for electric resistance welding of the utility model, comprise top electrode 1, bottom electrode 2 and electrode cap 3, described top electrode 1 matches with bottom electrode 2, described bottom electrode 2 top has vertical installing hole 21, positioning sleeve 4 is provided with in described installing hole 21, positioning sleeve 4 has endoporus, the outer wall of described positioning sleeve 4 is provided with spacing preiection 41, the tip edge of described positioning sleeve 4 is provided with the gear platform 42 of indent, described gear platform 42 is for supporting, card puts the workpiece that will weld, described electrode cap 3 is connected with bottom electrode 2, and be pressed against on the spacing preiection 41 of positioning sleeve 4, positioning sleeve 4 is limited in the installing hole 21 of bottom electrode 2 by the spacing preiection 41 that namely described electrode cap 3 is pressed against positioning sleeve 4.In the present embodiment, for the ease of electrode cap 3, location fit between positioning sleeve 4 and bottom electrode 2 three, described electrode cap 3 has through hole 31, and described positioning sleeve 4 is located in through hole 31, and is pressed against on spacing preiection 41; Further, described electrode cap 3 lower end is provided with external screw thread, and described electrode cap 3 is threaded with bottom electrode 2, thus facilitates electrode cap 3 to coordinate with the installation of bottom electrode 2.
In the present embodiment, the spacing preiection 41 on described positioning sleeve 4 is loop configuration, and then facilitates coordinating between electrode cap 3 with positioning sleeve 4, how positioning sleeve 4 is rotated in installing hole 21 all can not affect electrode cap 3 to be pressed against on spacing preiection 41.
In the present embodiment, described top electrode 1 and bottom electrode 2 are column structure.
Positioning sleeve 4 in the utility model is insulating materials, and when guaranteeing that top electrode 1 and bottom electrode 2 are energized, the screw thread of projection welding bolt can not be damaged.
The utility model is arranged on be connected (namely welding) for projection welding bolt and packing ring on projection welder, and as shown in Figure 2, the nut lower end of described projection welding bolt 6 is provided with multiple salient point 61.Top electrode 1 in the utility model is fixedly connected with the top of projection welder, bottom electrode 2 is connected with the bottom of projection welder, projection welder top and the bottom connect power positive cathode respectively, positioning sleeve 4 is installed and is limited in installing hole 21 by described electrode cap 3, and the gear platform 42 on described positioning sleeve 4 is higher than electrode cap 3, so that supporting bead.Composition graphs 1-Fig. 4, the operating procedure that projection welding bolt 6 and packing ring 7 are connected is: the power supply opening projection welder, call welding condition, packing ring 7 is enclosed within positioning sleeve 4 top in bottom electrode 2, namely described packing ring 7 be stuck in positioning sleeve 4 gear platform 42 on location, then top electrode 1 is inserted the Internal hole positioning of positioning sleeve 4 with projection welding bolt 6, and allow salient point 61 be pressed against on packing ring 7, then projection welder energising is operated, under pressure and the powerful function of current, salient point 61 on projection welding bolt 6 is fused into in packing ring 7, projection welding bolt 6 and packing ring 7 are connected, the weld assembly that final formation one is new.
