A diesel engine exhaust manifold bellows welding device

Abstract

The invention relates to a diesel engine exhaust manifold bellows welding device, which includes a support frame and a rotating shaft with a supporting disc arranged on it, the rotating shaft includes rotating shaft I and rotating shaft II; a motor and a transmission structure for driving the rotating shaft; welding The welding machine and the guide rail used for the movement of the welding machine are also provided with a guide slide rail on the support frame. The cylinder is connected to the rotating shaft I and drives the rotating shaft I to move within the range of the guide slide rail. When starting, the exhaust manifold bellows It is placed between the rotating shaft I and the rotating shaft II and is supported by a supporting disc. The motor drives the supporting disc to rotate, and the bellows of the exhaust manifold will rotate accordingly, so that the circular welding of the bellows can be realized, and it can be moved up and down, left and right when necessary. The cylinder can drive the rotating shaft to clamp the bellows of the exhaust manifold to prevent shaking. The invention can adapt to the welding of the bellows of the exhaust manifold with different sizes. The welding process is convenient and concise, no redundant steps are required, and the operation is simple and automatic. Batch automated production can be realized.

Description

technical field [0001] The invention relates to the field of exhaust manifold welding mechanisms, in particular to a diesel engine exhaust manifold bellows welding device. Background technique [0002] The exhaust manifold is connected to the cylinder block of the diesel engine. It collects the exhaust gas of each cylinder and guides it into the exhaust manifold. It has divergent pipelines. The bellows is a part of the exhaust manifold assembly. There is a certain corrugation, when the bellows and other parts need to be welded in a ring, there are not small technical problems for the existing welding equipment, which can easily lead to the misalignment of the bellows and other metal parts, seriously affecting the welding quality, and at the same time Manual operation, the position of the welding machine is not easy to control, which affects the welding efficiency, and often has the problem of uneven welding or unsightly welds, which in turn affects the overall performance of...
