Detailed ways

The utility model will be further described below with reference to the accompanying drawings and in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to FIG. 2 , the brazing fixture of the present invention is mainly composed of a pressing plate 1 , a bottom plate 2 , bolts 3 and nuts 4 . The size of the bottom plate 2, the pressure plate 1, the bolt 3 and the nut 4 in the brazing jig can be changed arbitrarily, and is suitable for brazing electrode assemblies of various sizes, and the use method of the jig is simple and convenient.

As shown in FIG. 3 and FIG. 4 , a first limiting slot 22 is provided in the upper middle of the bottom plate 2 , and a plurality of bolt holes 21 are provided in the outer periphery of the first limiting slot 22 . The number of bolt holes 21 can be set as required. In this embodiment, there are three bolt holes 21 , which are evenly arranged on the outer periphery of the first limiting groove 22 . Referring to FIG. 1 , the shape of the first limiting groove 22 is matched with the base 014 of the discharge tube electrode assembly, so that the electrode assembly can be placed in the first limiting groove 22 with the base 014 and fixed. As shown in FIG. 4 , in order to facilitate the adjustment of the position of the electrode assembly, the bottom of the first limiting groove 22 is provided with a first adjustment hole 23 penetrating to the bottom of the bottom plate 2 .
