Abstract

The invention discloses an overlap welding tool for a coordinating rod of a millimeter wave filter. The overlap welding tool comprises a positioning shell, baffles, springs, a push-pull rod, a feeler gauge and a shape righting plate, the baffles are symmetrically arranged in the positioning shell, the opposite side faces of the baffles are connected with one end of the push-pull rod, and the other end of the push-pull rod penetrates through the side face of the positioning shell; the push-pull rod is sleeved with the springs, the push-pull rod drives the baffles to compress the springs to move, a first through hole is formed in the top of the positioning shell, one end of the filler gauge penetrates through the first through hole, and coordination rods are arranged on the two sides of the filler gauge; and the shape righting plate is arranged on the positioning shell, a communicating rod is arranged in the shape righting plate, a weldment is placed at an overlap welding point of the communicating rod and the coordinating rods, and the communicating rod and the coordinating rods are fixed through the weldment. The welding precision and the welding consistency and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to a lap welding tool for a coordination rod of a millimeter wave filter. Background technique [0002] With the development of electronic information technology, subject to the limitation of frequency band and dimensional accuracy, traditional radar has been unable to adapt to signal positioning, tracking in broadband, high gain, ultra-low sidelobe, variable circular polarization, low return loss, etc. In terms of requirements, at present, the radar components that meet the information countermeasures of the new era basically adopt millimeter wave structures, and higher requirements are placed on internal dimension processing and assembly welding accuracy. As one of the core components of the radar structure, the filter mainly plays the role of frequency screening, attenuates redundant frequency signals, and retains designated frequency signals. As the key medium for adj...
