Embodiment 2

[0036] A laser welding method for a titanium pump core assembly, characterized in that it comprises the following steps:

[0037] A. In the lower mold 2, sequentially install the six anodes 11 in the titanium pump core assembly 10 into the anode positioning step 4, and then install the upper cover plate assembly 12 in the titanium pump core assembly 10 into the lead wire positioning step 6, And assemble the fixed piece 13 in the titanium pump pump core assembly 10 into the fixed piece positioning step 5;

[0038] B. Assembling the fixing band 14, using the pin 3 to attach the anode 11 to the fixing piece 13 and the fixing band 14, and inserting the pin 3 into the pin positioning step 7 in the lower mold 2;

[0039] C. Then the upper mold 1 is symmetrically installed on the lower mold 2, so that the pin 3 is embedded on the pin positioning step 7 in the upper mold 1, and the anode 11, the fixed piece 13 and the upper cover plate in the titanium pump core assembly 10 are made T...

Abstract

The invention discloses a laser welding tool for a pump core assembly of a titanium pump and a welding method thereof, which comprises: an upper mold (1), a lower mold (2) and a pin (3), the upper mold (1) and the lower The mold (2) has a symmetrical structure up and down; the upper mold (1) and the lower mold (2) are provided with an anode positioning step (4), a fixed piece positioning step (5), a lead wire positioning step (6), a latch positioning step ( 7), the light hole (8) and the light groove (9); the latch (3) is a U-shaped latch, and is embedded between the upper mold (1) and the lower mold (2) through the latch positioning step (7). The invention has reasonable structural design, precise positioning, high efficiency, high reliability and other advantages. The invention designs symmetrical upper and lower molds and pins, and sets positioning holes, fixed piece positioning grooves, light holes and light grooves, etc., effectively Control the assembly accuracy of the titanium pump core to ensure that the assembled anode frame and lead wire combination are coaxial to avoid anode deformation and anode misalignment during resistance spot welding.

Description

technical field [0001] The invention relates to a processing device for a pump core assembly of a titanium pump, in particular to a laser welding tool for a pump core assembly of a titanium pump and a welding method thereof. Background technique [0002] As the most important high-power microwave amplification device at present, traveling wave tube is a key component of electronic equipment such as radar, electronic countermeasures, relay communication, satellite communication, live TV satellite, navigation, remote sensing, remote control and telemetry. Due to the high angular resolution and wide frequency bandwidth, the millimeter wave technology can use a smaller antenna to obtain a very narrow beam width, and can obtain more information about the measured target. It is used in defense equipment such as radars, communication satellites, and electronic countermeasures. , early warning aircraft and precision guidance have an important role and broad application prospects. ...
