Semi-automatic welding equipment for automobile water falling groove

Abstract

The invention discloses semi-automatic welding equipment for an automobile water falling groove. The semi-automatic welding equipment comprises a workbench, a welding device, a welding clamp and a controller. The welding device comprises a vertical rod, a sliding block, a telescopic arm and a welding gun. The vertical rod is fixedly arranged on the workbench, the sliding block sleeves the verticalrod, the telescopic arm is perpendicular to the vertical rod, and the telescopic arm is fixedly connected with the sliding block. The welding gun is fixedly arranged at the free end of the telescopicarm, a balancer is arranged at the upper end of the vertical rod, the sliding block is connected with the balancer, and a laser displacement sensor and a displacement sensor are arranged on the telescopic arm. The position of the telescopic arm is taken as an X axis, when the telescopic arm is completely contracted, the position of a gun head of the welding gun is a zero point, the position of the vertical rod is a Z axis, the surface of the workbench is a reference surface, each welding spot is provided with a specific X value and a specific Z value, and when the X value and the Z value aremet at the same time, the welding gun works. The semi-automatic welding equipment for the automobile water falling groove can perform fixed-point welding, the welding gun only works at a specific position, wrong welding and excessive welding are avoided, and misoperation is avoided; and the welding depth can be detected, and the welding quality is controlled.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a semi-automatic welding equipment for an automobile gutter. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the quality of automobiles. The car gutter is a part that can be seen after the rear cover of the car is opened. It belongs to the B+ category parts. The surface quality requirements of the gutter are very high, and the surface quality requirements are equal to the quality requirements of the outer covering parts of the car. Therefore, the welding of the sink has high requirements on the surface quality of the parts, and the indentation depth of the solder joints cannot exceed 15%. At present, arc-shaped electrode caps are used for the welding of car gutters, which are clamped by general fixtures. The depth of indentation of solder joints cannot be guaranteed, and the welding quality c...
