Spot-welding positioning mechanism for process gasket of protector

Abstract

The invention discloses a spot-welding positioning mechanism for a process gasket of a protector, comprising a base, a lower electrode, a positioning plate, an upper electrode, a guide rod, a bracket and a spring, wherein an electrode groove, a connecting arm and a bracket seat are arranged on the base; the positioning plate is provided with a containing chamber and a first guide rod hole; an electrode movable sleeve is arranged on the upper electrode; a second guide rod hole and an installing hole are arranged on the bracket; the lower electrode is vertically arranged in the electrode grooveof the base; the installing hole of the bracket is fixedly connected with the bracket seat; the guide rod is arranged in the two guide rod holes of the bracket; the containing chamber of the positioning plate is sleeved on the lower electrode; the first guide rod hole is sleeved on the guide rod; the spring is sleeved on the guide rod, and arranged between the positioning plate and the bracket; and the upper electrode is located above the lower electrode, and is connected with the connecting arm through the electrode movable sleeve. The spot-welding positioning mechanism for the process gasket of the protector has the advantages of simple structure, convenience in manufacture, easiness in placing the process gasket, and accuracy and reliability in positioning.

Description

technical field [0001] The invention relates to the welding of thin slices and small-sized components in the field of welding tooling technology, in particular to a spot welding positioning mechanism for protector process gaskets. Background technique [0002] The key component of the built-in protector is the combination of three metal sheets. The three metal sheet combination is made of a combination of three metal sheets, moving contact pieces and process gaskets through spot welding. Since the thickness of the three metal sheets is extremely thin, the moving contact piece The thickness of the three-metal sheet is four times that of the three-metal sheet. In order to meet the welding performance of the three-metal sheet and the moving contact piece and ensure the welding quality, a process must be added on the other side of the moving contact piece when the three-metal sheet and the moving contact piece are spot welded. Gasket, so that the three-metal sheet is located...

AI Technical Summary

Problems solved by technology

The problem is that when the process gasket moves on the electrode with negative pressure, due to the poor stability of the air pressure adsorption, the radial direction of the process gasket cannot be positioned. When the process gasket moves to the welding position, the radial direction of the process gasket Movement is unavoidable, which affects the accuracy of positioning and directly affects the product quality of the three-metal sheet combination
