The invention provides a welding clamp of an automobile engine exhaust system exhaust taper pipe inner shell. The welding clamp comprises a clamp base plate and is characterized in that a small-circular-opening positioning clamping mechanism and a large-circular-opening positioning clamping mechanism are mounted on the clamp base plate, the small-circular-opening positioning clamping mechanism comprises a small-circular-opening positioning block, an upper shell small-circular-opening clamping block and a lower shell small-circular-opening clamping block, the large-circular-opening positioning clamping mechanism comprises a large-circular-opening positioning block, an upper shell large-circular-opening clamping block and a lower shell large-circular-opening clamping block, the upper shell small-circular-opening clamping block, the lower shell small-circular-opening clamping block, the upper shell large-circular-opening clamping block and the lower shell large-circular-opening clamping block are respectively driven by link mechanisms to clamp an upper shell and a lower shell on the large-circular-opening positioning block and the small-circular-opening positioning block. The welding clamp is capable of reliably positioning and clamping the upper half shell and the lower half shell, and shell welding is guaranteed.
Description
technical field [0001] The invention relates to the field of processing tooling for automobile engine parts, in particular to a welding fixture for the inner shell of an exhaust cone pipe of an automobile engine exhaust system. Background technique [0002] An inner casing of an exhaust cone pipe of an automobile engine exhaust system, the structure of which is shown in figure 1 , which is welded by the upper half shell 15 and the lower half shell 16, because the axis line of the large round mouth and the axis line of the small round mouth of the product form a certain angle, and the workpiece is a thin-walled part, so the upper When the half shell and the lower half shell are welded, the workpiece is not easy to be positioned and clamped, and the problem of crushing the outer surface of the workpiece is easy to occur during the clamping process. figure 1 Among them, 17 is a welding seam, 18 is a large round mouth, and 19 is a small round mouth.
