A positioning guide riveting device for busbar

Abstract

The invention discloses a positioning guiding riveter for busbars. The positioning guiding riveter comprises a base, a guide sleeve and a riveting bar. The top of the riveting bar penetrates the guide sleeve; the riveting bar can vertically move up and down. An elastic element is disposed between the riveting bar and the base, which have a spacing h. The upper surface of the guide sleeve is provided with a positioning hole. The upper portion of the riveting bar comprises a metal plate positioning guiding segment, a binding post positioning segment and a transition segment; before a metal plate is riveted to a binding post, the metal plate positioning guiding segment is disposed at a height a in a riveting hole of the metal plate, a distance from the top of the transition segment to the upper surface of the guide sleeve is b, and a is greater than b / 2; during riveting of the metal plate and the binding post, a riveting segment of the binding post replaces the riveting bar to position the metal plate. The positioning guiding riveter can position one of two pieces to be riveted, and one piece is accurately guided to the other under the action of pressure and is riveted to the positioned piece to be riveted; operational convenience is improved, and riveting quality is stabilized.

Description

technical field [0001] The invention relates to a positioning and guiding riveting device for a bus bar, which is especially suitable for reliable riveting between a metal plate and a terminal post. Background technique [0002] Metal plate and terminal riveting is a common connection process for composite busbars, usually using pressure riveting or spin riveting. [0003] Pressure riveting is connected by interference fit between the riveted parts. It is necessary to preliminarily assemble and fix the terminal and the metal plate in advance, referred to as pre-riveting. It is necessary to ensure that the terminal is perpendicular to the metal plate, and then apply a certain pressure to press the terminal into holes in the sheet metal to make them join (see figure 1 ). The operation steps include pre-riveting and pressure riveting, which may cause crush defects because the terminal is not perpendicular to the metal plate. [0004] Rotary riveting is a riveting method in w...

The operation steps include pre-riveting and pressure riveting, which may cause crush defects because the terminal is not perpendicular to the metal plate

[0004] Rotary riveting is a riveting method in which the riveting rod is used to locally pressurize the terminal, and continuously swing around the center, and the small end of the extruded terminal is deformed so as to be firmly connected with the hole wall of the metal plate (see figure 2 ), the riveting rod only exerts pressure on the inner wall of the small end of the terminal, and cannot guarantee that the terminal is completely perpendicular to the metal plate. Therefore, it is easy to generate a gap between the terminal and the metal plate, which affects product quality
