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 [0001] The invention relates to a dynode assembly welding fixture, which belongs to the technical field of surface engineering. Background technique [0002] The electron multiplier is a key component of a small cesium atomic clock, and the dynode is an important component of the electron multiplier. Its assembly and welding process seriously affects the performance of the device. Therefore, the research on the oxidation-free rapid assembly technology of the electron multiplier dynode is very meaningful and necessary. Dynode assembly is the process of fixing the grid on the inlet of the curved tile shell by spot welding using the grid clamp. Using spot welding equipment. In the general welding process, first align the grid, the pressing piece and the arc-shaped tile shell, and then use two pliers to respectively clamp the two sides of the pressing piece and the opposite sides of the arc-shaped tile shell, and perform welding on the other two sides. Weld th...
