Abstract
The invention relates to a dynode assembly welding fixture, which belongs to the technical field of surface engineering. A copper block of the welding fixture is provided with one or more rectangular holes, each rectangular hole is provided with four edges a, b, c and d, first grooves are respectively arranged on the upper surface of the copper block along the inner sides of the edges b and d and extend towards the edge of the copper block along the inner sides of the edges b and d, second grooves are respectively arranged on the upper surface of the copper block along the outer sides of the edges a and c and are intersected and integrated with the first grooves along the outer sides of the edges a and c, and the depth of each first groove is as same as that of each second groove. The sizes of the rectangular holes, the first grooves and the second grooves meet the requirement of placing a dynode with an upward grid mesh plane and a downward arc tile shell into the rectangular holes, the first grooves and the second grooves. The fixture is capable of meeting the requirement of the dynode of an electron multiplier on assembly welding, the difficulty of a welding process for the dynode is reduced, and assembly time is shortened.
Description
Technical field
The present invention relates to a kind of dynode erection welding fixture, belong to field of surface engineering technique.
Background technology
Electron multiplier is the critical component of small-sized cesium-beam atomic clock, and dynode is the significant components of electron multiplier, and its erection welding technique has a strong impact on device performance, so the non-oxidation rapid assembly technique of electron multiplier dynode is studied highly significant and necessity.Dynode assembling is to utilize aperture plate compressing member, by spot welding, aperture plate is fixed on to the process on arc tile shell entrance.Employing spot-welding equipment carries out.In general welding process, first, by aperture plate, compressing member and the alignment of arc tile shell, then use two hand vice to clamp respectively compressing member and both sides, arc tile shell opposite, carry out the welding of other both sides, with same procedure welding, pressed from both sides both sides.Welding process will be passed through repetition test, determines the order of suitable voltage, spot welding pressure and the welding side of spot welding, obtains ripe welding method.Because dynode element size is little, exquisite in workmanship, in above-mentioned erection welding process, parts are difficult for the features such as fixing, precise part is fragile, operation easier is large, make assembly technology operability, poor repeatability and installation time long, be unfavorable for the performance of integral device.
Summary of the invention
The object of the present invention is to provide a kind of dynode erection welding fixture, there is easy to operate, securing part position fast.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of dynode erection welding fixture, described fixture for having one or more rectangular openings on copper billet, four limits of rectangular opening are respectively a, b, c, d, at copper billet upper surface, along b, inner side, d limit, have groove one, groove one extends along side direction copper billet edge in b, d limit, at copper billet upper surface, along a, outside, c limit, have groove two, groove two intersects and merges with groove one along a, outside, c limit, and groove one is identical with groove two degree of depth.
Wherein, the size of rectangular opening, groove one and groove two meet by aperture plate plane upward, arc tile shell dynode down puts into.
Wherein, preferably groove one degree of depth is 0.7～1mm, and width is 1mm; Groove two degree of depth are 0.7～1mm, and width is 1.4mm;
A using method for dynode erection welding fixture, the erection welding process of described dynode is as follows:
Step 1, with alcohol or acetone ultrasonic cleaning weld jig, aperture plate, compressing member one, compressing member two, arc tile shell;
Step 2, weld jig reeded is faced up; Successively arc tile shell, compressing member two, aperture plate, compressing member one are positioned in weld jig;
Step 3, a use point welding stage, be symmetrically welded 6～10 solder joints at compressing member one and four edges of the superimposed position of middle aperture plate.
Beneficial effect
Dynode erection welding fixture of the present invention, can meet the erection welding requirement of electron multiplier dynode, reduces the difficulty of dynode welding procedure, shortens installation time.
