Object of the present invention is achieved through the following technical solutions: the welding spot positioning device that can adapt to multiple automobile premuffler, comprise workbench, on described workbench, be provided with limiting plate, limit base, supporting base and two parallel chutes, the lower end of described limit base be provided with two with two runner positions projection of corresponding and big or small coupling one by one, two projections of described limit base embed respectively in two chutes, described supporting base is between limiting plate and limit base, described limiting plate movable upper end is connected with pad localization chi, the other end that described pad localization chi connects limiting plate end is relatively provided with the solder joint index aperture that runs through pad localization chi upper and lower end face.
On workbench 1 between described two chutes, be provided with a plurality of screwed holes, a plurality of screwed holes are set to a row, and the line of a plurality of screwed hole central points is the straight line of parallel two chutes.The present invention time can embed in screwed hole by bolt in application, so while preventing from placing silencing pot limit base to the side's skew away from supporting base.
The upper end of described limiting plate is connected with set bolt, and the link of described pad localization chi and limiting plate is provided with positional punch, and described pad localization chi is set on set bolt and is flexibly connected with limiting plate by its positional punch.Pad localization chi of the present invention is connected on limiting plate by set bolt, is convenient to dismounting.
The upper end of described supporting base is provided with runs through it over against the arc notch of limiting plate and limit base both ends of the surface, and described limit base forms the horizontal backing plate that horizontal level is identical with supporting base arc notch bottom level position.The present invention is by arc notch is set on supporting base, and the degree of crook of its arc notch should mate for the arc-shaped curved surface of fixing silencing pot with the present invention, by the effect of arc notch, can avoid silencing pot displacement.
Described limiting plate is connected with spacing termination over against the end face of limit base.The present invention is when application, and silencing pot, between spacing termination and limit base, avoids silencing pot to be close to the rotation that limiting plate affects pad localization chi by the interaction energy of spacing termination.The present invention when setting, should guarantee pad localization chi between limiting plate and limit base and during vertical limiting plate its solder joint index aperture apart from the distance of spacing termination, be 19.5～20.5cm.
The quantity of described supporting base is two.The present invention, by the effect of two supporting bases, more can keep the balance of silencing pot when fixedly disappearing silencing pot.
Compared with prior art, the present invention has following beneficial effect: the present invention includes limiting plate, limit base, supporting base and two parallel chutes, wherein limit base is provided with two and embeds respectively two projections in chute, limiting plate movable upper end is connected with pad localization chi, the other end that pad localization chi connects limiting plate end is relatively provided with solder joint index aperture, overall structure of the present invention is simple, be convenient to realize, when the present invention applies, according to the length of the silencing pot of automobile premuffler, adjust the position of limit base, and to it, the side away from supporting base positions by bolt, silencing pot is fixed on supporting base and makes it buckle seam upward, and to the two ends of silencing pot, carry out spacing by limit base and limiting plate, by rotating pad localization chi, be located between limiting plate and limit base and vertical limiting plate again, now by operating personnel, with pen, through weldering, determine locating hole mark solder joint, so, operating personnel are energy precise positioning when carrying out postorder spot welding, and then detain seam place can avoid flange time and occur gap, guaranteed the yield rate of the silencer made, in the present invention, the position of limit base is adjustable, so makes the present invention can adapt to the silencing pot of different length in certain limit, and this has just increased range of application of the present invention.
