Abstract
The utility model discloses a spacing shim for manufacturing electron gun, comprising a rectangle shim body and a through hole which is arranged in the shim body. Two long margins of the rectangle shim body are respectively equipped with a symmetrical groove. The spacing shim is arranged in the burning gun procedure of electron gun manufacture. The spacing shim is inserted among all the electrode assemblies to guarantee accuracy of size of space among the electrode assemblies. Then, the electrode assembly is pre-welded using a laser-beam welding machine. After welding, the spacing shim is drown out. Because sometime welding occurs beside the spacing shim, welding spot is easy to occur on the spacing shim generating burr and the electrode assembly is scratched by the shim during use. The utility model is provided with a groove corresponding to the welding spot location, avoiding burr phenomenon occurring during welding process.
Description
Technical field
The utility model belongs to the production of kinescope field, particularly a kind of employed pad when in the electron gun production process of picture tube electron gun electrodes being carried out laser welding.
Background technology
Burn in the rifle operation at picture tube electron gun, need be assembled into each electrode assemblie and spacing washer on the anchor clamps after, wherein two or more assemblies are carried out laser welding.Spacing washer is used for guaranteeing the spacing between the electrode assemblie, to satisfy technical specification.If welding occurs in pad closely the time, solder joint is beaten easily and produce burr on pad, makes in the pad plug use afterwards the electrode assemblie end face is produced scuffing.And the scuffing of electrode can make picture tube work the time point discharge, sparking occur, and the serious whole picture tube that causes is scrapped.
Summary of the invention
The purpose of this utility model be to provide a kind of in welding process solder joint do not damage the electron gun manufacturing spacing washer of shim body away from pad.
For achieving the above object, the technical solution adopted in the utility model is: comprise a rectangular washer body and be arranged on through hole on the shim body, offer the groove of symmetry in the outside of rectangular washer body respectively.
Because the utility model offers groove in shim body and the corresponding position of solder joint, avoided in welding process the burr of pad has been eliminated in the damage of shim body.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is user mode figure of the present utility model.
Referring to Fig. 1, the utility model comprises back rectangular washer body 1, offers a through hole 2 on the rectangular washer body 1, and offers the groove 3 of symmetry on two long limits of rectangular washer body 1 respectively.
Referring to Fig. 1,2, the utility model is slotted to the spacing washer of present use, makes electrode assemblie in welding process, and solder joint is away from pad.In the burning rifle operation that electron gun is made, between each electrode assemblie, insert spacing washer 1, be used for guaranteeing the size of space precision between each electrode assemblie, with laser-beam welding machine electrode assemblie is carried out pre-welding then, again spacing washer 1 is released after having welded, in use shim body 1 is arranged on two electrode assemblies 4,5 lower end, electrode assemblie 4,5 by laser welding more together, two solder joints 6 are arranged on the contact-making surface during welding, drop on because of carelessness on the spacing washer 1 for fear of solder joint, offer in the relevant position of pad and solder joint and to be equipped with two grooves 3, make pad 1 and solder joint 6 keep bigger distance, thereby avoided in the welding process generation of pad burr phenomena has been eliminated in the damage of pad.
