Abstract

The invention discloses a positioning mechanism for improving the welding efficiency for an exhaust manifold and a flange. The positioning mechanism for improving the welding efficiency for the exhaust manifold and the flange comprises a base. A plurality of first driving mechanisms are arranged at the top of the base, and the first driving mechanisms can move on the base. Each first driving mechanism comprises a first driving shaft, wherein a clamping plate used for clamping the exhaust manifold is arranged at the top of the first driving shaft. A second driving mechanism is further arranged at the top of the base and can move on the base. The second driving mechanism comprises a second driving shaft, wherein a side table is arranged at the top of the second driving shaft, and the side table can rotate around the second driving shaft; and limiting plates used for clamping the flange are arranged on the side table. By adoption of the poisoning mechanism for improving the welding efficiency for the exhaust manifold and the flange, exhaust manifolds in different shapes can be clamped, and the weld portions of the flange and the exhaust manifold can be aligned conveniently.

Description

technical field [0001] The invention relates to a processing tool for automobile parts, in particular to a positioning mechanism for improving the welding efficiency of exhaust manifolds and flanges. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine, and gathers the exhaust of each cylinder into the exhaust manifold, with divergent pipelines. The main requirements for it are to minimize exhaust resistance and avoid mutual interference between cylinders. When the exhaust is too concentrated, there will be mutual interference between the cylinders, that is, when a certain cylinder exhausts, it happens to encounter the undischarged exhaust gas from other cylinders. In this way, the resistance of the exhaust will be increased, thereby reducing the output power of the engine. The solution is to separate the exhaust of each cylinder as much as possible, one branch for each cylinder, or one branch for two cylinders, and make each ...
