[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0018] Please refer to Figures 1 to 5The utility model provides a technical scheme: a positioning tool for hot riveting of arc extinguishing chamber, including base 1 and the bottom plate 2 of fixed in the top of base 1, the top fixed mounting of bottom plate 2 has the stand 3, the top detachable mounting of bottom plate 2 has the cushion block 5, because different models of arc extinguishing chamber have different sizes, therefore through setting up detachable cushion block 5, to facilitate the limiting of different size arc extinguishing chamber, expand its scope of application, the side of stand 3 close to cushion block 5 is equipped with limit block 7 symmetrically, the top of cushion block 5 integrally has two protrusions 8, limit block 7 and protrusion 8 can be used for the limiting of arc extinguishing chamber, and arc extinguishing chamber can be clamped into gap 6 also can play the limiting effect, to avoid in the hot riveting of arc extinguishing chamber, arc extinguishing chamber occurs deviation, influence hot riveting effect, the top of stand 3 is installed with top plate 4, and the side of top plate 4 close to limit block 7 is equipped with gap 6.

[0019] Wherein, the through hole 9 is arranged on the cushion block 5, and the second threaded hole 12 corresponding to the through hole 9 is arranged on the top of the bottom plate 2, and the cushion block 5 can be fixed on the bottom plate 2 by screwing the screw into the second threaded hole 12 through the through hole 9.

[0020] Wherein, the first threaded hole 11 is arranged on the top of the stand 3, and the fixing hole 10 corresponding to the first threaded hole 11 is arranged on the top plate 4, and the top plate 4 can be fixed on the stand 3 by screwing the screw into the first threaded hole 11 through the fixing hole 10.

[0021] Wherein, the distance between the two protrusions 8 is greater than the distance between the two limit blocks 7, so that the opposite side walls of the two protrusions 8 are staggered with the opposite side walls of the two limit blocks 7, so as to facilitate the limiting of the arc extinguishing chamber.
