Abstract
The assembly welding clamp for color kinescope electron gun parts relates to the welding clamp for electron gun combined parts. The technical scheme includes that the cylindrical part is accurately positioned by the boss-shaped lower fixture, the built-in part is positioned at a required position through the elliptical cylindrical positioning pin above the lower fixture and the elliptical cylindrical hole of the upper fixture for welding, the fixture has the advantages of being simple in structure and accurate and reliable in positioning, the built-in part and the cylindrical part can be overlapped through the center of the central electron beam through hole, and a part assembly subjected to laser welding can meet requirements on symmetry and embedding depth.
Description
The utility model relates to the weld jig of electron gun component parts.Especially refer to the positioning fixture when a kind of colorful visualization tube electron gun component parts welds, wherein soldering part is built-in part and has the cylindrical part partly of extending.
In colour display device and data presentation device, influencing the focusing performance of color picture tube and assembling one of conforming factor of performance is the symmetry of its electron gun main lens electrode part assembly, and the symmetry of component parts is by the accuracy of manufacture of single part and the common decision of part assembly welding precision, for built-in part main lens electrode is arranged, the portion that the extends inboard of cylindrical part often is difficult to reach higher level with the accuracy of manufacture of the symmetry of the inner edge that turns edge that forms the common lens of main lens, and the higher built-in part of the accuracy of manufacture is to be welded on the cylindrical part portion inboard of extending, with the cylindrical electrode part built-in part of the inboard location welding of portion of extending, tend to cause that the precision of center, component parts hole symmetry is not high.
The purpose of this utility model is to provide a kind of assembly welding anchor clamps of color picture tube parts of electronic gun.
The utility model is achieved through the following technical solutions: the lower clamp with the boss shape is accurately located cylindrical part, and cooperates with the elliptical aperture of last anchor clamps by the oval pin of lower clamp top, makes built-in part be positioned desired location and welds.
The utility model is simple in structure, and the location is accurately reliable, and built-in part is overlapped with the center of cylindrical part center electron beam by the hole, and the part assemblies of carrying out after the laser welding can satisfy symmetry, the requirement of insert depth.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing 1 is the utility model exploded view.
Accompanying drawing 2 is the component parts structural representation
See accompanying drawing 1,2, the utility model comprises anchor clamps 1, lower clamp 2, one boss 26 is arranged on the lower clamp 2, its baseplane 27 is the locating surface on cylindrical part 3 flange planes 32, its outer rim is the locating surface of the flange inner edge 31 of cylindrical part 3, twice deep trouth 24 is arranged on boss 26, the last plane 21 of boss 26 is the locating surface of built-in part 4, oval alignment pin 22 is arranged on the boss 26, on oval alignment pin 22, can offer vertical, transverse groove 221, on boss 26 and the oval alignment pin 22 chamfering 25 is arranged all, 23, the elliptical aperture 12 of last anchor clamps 1 be on the lower clamp 2 oval alignment pin 22 pass through the hole, the plane 11 of last anchor clamps 1 is pressed on the plane of built-in part 4.
When using the utility model, cylindrical part 3 is nested with outside boss 26, the flange plane 32 of cylindrical part 3 is fitted on the baseplane 27 of boss 26 of lower clamp 2, the flange inner edge 31 of cylindrical part 3 is fitted on the outer rim of boss 26, because of deep trouth 24 is arranged on the lower clamp 2, so the flange inner edge 31 that metallic spring distortion has guaranteed cylindrical part 3 is when certain margin of tolerance, its center invariant position.Again the elliptical aperture 41 of built-in part 4 is enclosed within the oval alignment pin 22 on the lower clamp 2, strain vertical, that groove is produced to groove 221 on the oval alignment pin 22 makes built-in part 4 automatic centerings, pad 43 on its built-in part 4 touches the inwall 33 of cylindrical part 3, fasten again and go up anchor clamps 1, can on the outer wall 34 of cylindrical part 3, use laser welding, cylindrical part 3 and built-in part 4 are connected as a single entity by solder joint 35.
