Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and the auxiliary welding device of a kind of combined resistance easy to use is provided.
The purpose of this utility model can be achieved through the following technical solutions: the auxiliary welding device of a kind of combined resistance, for two metalfilmresistors being welded into the combined resistance of U-shaped shape, in described combined resistance, two metalfilmresistors are the most parallel, this device includes welding bench, fixed block and clamp system, described fixed block is arranged on welding bench, for placing the pin of two metalfilmresistors, described clamp system is connected with fixed block, during welding, described clamp system clamping metalfilmresistor.
The rectangular shape of described fixed block is the most one-body molded with described welding bench.
Described fixed block is the fixed block being made up of polypropylene.
Described welding bench is the welding bench being made up of polypropylene.
Described clamp system includes fastening bolt, band annular knurl hands the turn of the screw and securing member, the U-shaped shape of described securing member, its U-shaped opening snaps in described fixed block, described securing member is provided with the perforate for inserting fastening bolt, during welding, described band annular knurl hands the turn of the screw screws in fastening bolt, makes described securing member extruding metalfilmresistor, makes metalfilmresistor be adjacent on fixed block.
Described securing member is the securing member of Milling Machining molding.
Described clamp system also includes the packing ring being socketed in fastening bolt.
The length of described fixed block is equal with the horizontal range of two metalfilmresistors.
Compared with prior art, this utility model has the advantage that
(1) welding bench of this device, securing member use polypropylene material, welding bench and fixed block to use injection one-shot forming, and precision is high, and polypropylene material is the thermoplastic engineering plastic of a kind of high-melting-point, high crystalline, possesses antistatic performance；
(2) securing member is with Milling Machining form molding, saves processing cost；
(3) clamp system that the hands the turn of the screw of band annular knurl is combined with securing member, the fixing degree of tightness of scalable combined resistance, fixing convenient more many than former bolt, and material is more more robust than stainless steel material, safety；
(4) two metalfilmresistors get final product welding fabrication after requiring bending pin according to welding bench operation, and its overall dimensions is just meeting the space requirement of product；
(5) this device be easy to production scene fix metalfilmresistor and control expose pin welding and cut off size, reduce welding operation easier, it is ensured that the concordance of product after resistance welding, shorten the overall manufacturing cycle, improve production efficiency；
(6) this device decrease new hand to after resistance seam because of position deviation, the phenomenon often done over again.
