Description

Technical Field

[0001] The utility model relates to the field of welding auxiliary devices, in particular to a welding positioning frame. Background Art

[0002] The current brazing process for ceramic-cased DC relays typically involves first positioning the metallized ceramic housing, the copper pillars at the lead terminals, and the metal kovar frame before securing and welding them. Due to mechanical and processing errors that can occur during the manufacturing process, using a fixed auxiliary positioning system cannot eliminate these errors, resulting in significant assembly deviations. This means that the component tolerances, combined with the tolerances after assembly, increase the tolerance value, impacting product quality during welding. Utility Model Content

[0003] The purpose of the utility model is to provide a welding positioning frame, aiming to improve the problem of relatively poor production quality of the existing brazing process of ceramic shell DC relays.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: a welding positioning frame, comprising:

[0005] A bottom plate, wherein a positioning groove is provided on its plate surface, wherein a first longitudinal adjustment hole and a second transverse adjustment hole are provided in the positioning groove, wherein two longitudinal sliding posts are provided in the first adjustment hole, and two transverse sliding posts are provided in the second adjustment hole; and

[0006] A top plate is provided with a plurality of support rods between the top plate and the bottom plate, one end of the support rod is provided between the positioning groove and the side of the bottom plate, and a plurality of process holes are provided on the top plate.

[0007] Preferably, the first adjustment hole is a first elongated hole or two symmetrically arranged first elongated holes;

[0008] A first adjustment gap is provided between the first elongated hole and the wide side of the positioning groove.

[0009] Preferably, an annular boss is provided in the middle of the first adjustment hole.

[0010] Preferably, the second adjustment hole is provided in plurality, and the second adjustment hole is one second elongated hole or two symmetrically arranged second elongated holes;

[0011] A second adjustment gap is provided between the second elongated hole and the long side of the positioning groove.

[0012] Preferably, a plurality of weight-reducing holes are provided in the middle of the positioning groove.

[0013] Preferably, a plurality of abutting protrusions are arranged at intervals on the side surface of the process hole.

[0014] Preferably, internal threaded holes are provided on the bottom surfaces of the longitudinal sliding column and the transverse sliding column.

[0015] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0016] 1. Designing horizontal and vertical adjustment holes in the baseplate's positioning slots allows the longitudinal slide post to be adjusted along the first adjustment hole, while the horizontal slide post can be adjusted along the second adjustment hole. This eliminates inherent product errors and tolerances (for example, in the welding process between the metallized ceramic housing, the lead-out copper post, and the metal Kovar frame). It also provides a secure positioning mechanism, preventing assembly deviations between parts and improving welding positioning accuracy, thereby enhancing product quality.

Of course, for the positioning welding with the box opening, it can be used.

[0035] Specifically, a positioning groove 101 is provided on the bottom plate 10 to form a placement for aligning the kovar frame of the metal shell. At the same time, by using the horizontal and vertical adjustment holes, the longitudinal sliding column 1013 can be adjusted in size along the first adjustment hole 1011, and the transverse sliding column 1014 can be adjusted in size along the second adjustment hole 1012. In this way, the problems of errors or tolerances existing in the kovar frame of the metal shell itself can be eliminated, and stable limiting can be carried out. Subsequently, a metallized ceramic housing is placed on the kovar frame of the metal shell, and lead-out terminal copper columns are assembled on the metallized ceramic housing. The lead-out terminal copper columns can be aligned and assembled through the process hole 201 on the top plate 20, and the two end faces are limited by the bottom plate 10 and the top plate 20. In this way, the top plate 20 can be used for limiting, and the sliding columns of the bottom plate 10 can be adjusted.
