Welding clamp for automobile roof drip

Abstract

The invention relates to a welding clamp used for an automobile roof drip. The welding clamp comprises a mounting plate, a cylinder, a positioning block, a positioning pin, a pressing rotary arm and a pressing block, wherein the cylinder is fixed on the rear side of the mounting plate, the positioning block and the positioning pin are both fixed on the front side of the mounting plate, the pressing rotary arm is connected with a connecting rod of the cylinder, the pressing block is fixed on the pressing rotary arm and located right above the positioning block, the pressing rotary arm is provided with a copper plate which is located between the pressing block and the positioning block, the cylinder drives the pressing rotary arm to be lifted through the connecting rod so that the positioning pin penetrates through a positioning hole of the roof drip, a positioning face of the roof drip is located on the positioning block, the cylinder drives the pressing rotary arm to press downwards, the pressing block on the pressing rotary arm presses downwards to tightly press the roof drip, after pressing downwards along with the pressing rotary arm, the copper plate is located on a welding point to be welded, and when the roof drip is welded, one side of a welding gun makes contact with the copper plate while the other side of the welding gun makes contact with the roof drip. Compared with the prior art, the welding clamp is simple in structure and good in welding effect.

Description

technical field [0001] The invention relates to a jig, in particular to a welding jig used 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%. The arc-shaped electrode cap is used for the welding of the car gutter, and it is clamped by the current general fixture. The indentation of the solder joints cannot be guaranteed, and the welding quality cannot meet the customer's requirements. Contents o...
