Tool fixture capable of fixing position of welding point and preventing welding leakage

Abstract

The invention discloses a tool fixture capable of fixing the position of a welding point and preventing welding leakage. The tool fixture includes a mechanical structure part controlled by a controller and an electrical control part; the mechanical structure part includes a trolley, a bottom plate, a pressure plate, an air cylinder and a welding leakage preventing lamp plate; the pressure plate isprovided with several holes; and the electrical control part includes an SB1 main power switch, an SB2 start button switch, a relay, a solenoid valve, a switch sensor and a green lamp. The tool fixture fixes the welding position through the pressure plate fixing holes, the green lamp is electrically controlled to prevent welding leakage, the welding stability is improved, the welding quality is ensured, the inspection intensity of quality inspectors is reduced, and the tool fixture has universality.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a fixture capable of fixing the positions of welding spots and preventing missing welding. Background technique [0002] At present, most of the sound insulation cotton assembly of automobile interior parts adopts welding assembly method. The general welding method adopts the combination of product fixed base fixture and ultrasonic machine for manual welding. This method of welding is only manual welding according to the operation standard. Because it is difficult for workers to determine the specific solder joint position, solder joint offset and missing welding often occur. The sound insulation cotton is easy to fall off and lead to defective products, and the quality requirements of auto parts are getting higher and higher, and some models have been required to achieve a certain pulling force for welding. Contents of the invention [0003] The purpose of the present invent...
