Description

technical field [0001] The invention belongs to the technical field of automobiles, and more specifically relates to a press-fitting device for press-fitting a bowl-shaped plug of an engine cylinder block and cylinder head. Background technique [0002] Taking the engine cylinder head machining production line as an example, when the cylinder head is being cast, sand outlet holes need to be reserved. After the sand outlet holes are machined, the sand outlet holes must be press-fitted and sealed, and leak testing must be carried out after sealing . The original press-fitting device will have quality problems such as bowl-shaped plug leakage, over-pressure, and pressure skew. In order to improve the quality and efficiency of its automated plugging, it is necessary to redesign an efficient press-fitting plugging device. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a bowl-shaped plug p...
