The upper end of described limiting plate is connected with 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 bolt and is flexibly connected with limiting plate by its positional punch.Pad localization chi of the present invention is bolted on limiting plate, 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: (1) the present invention includes limiting plate, limit base and the supporting base between limiting plate and limit base, wherein, 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, the silencing pot of automobile premuffler 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, use a 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.
(2) limiting plate of the present invention upper end is provided with positioning rule limited post, when pad localization ulnar side wall is close to positioning rule limited post when mark solder joint, made the vertical limiting plate of pad localization chi, the present invention guarantees the vertical limiting plate of pad localization chi by the interaction energy of positioning rule limited post, thereby further improves the precision that solder joint indicates.
