[0002] The working environment of an automotive water pump is harsh, with not only high temperatures but also vibrations, flying dust pollution, etc. To prevent faults such as component loosening and water leakage, an interference fit is used between the water pump components and the pump housing. Analyzing from the water pump structure, when assembling each component into the pump housing, the assembly sequence should be to first press-fit the water pipes separately, and then press-fit the core shaft and the electromagnetic coil.

[0003] For the water pump assembly, each component's press-fitting machine is designed separately according to the process. Considering economy, a pneumatic booster is selected as the press, and press-fitting toolings are made separately. The components of this water pump are not on the same axis or in the same plane. The press must press-fit each component in sequence. Among them, the water pipes need to be installed at different positions of the water pump, and there is an interference fit between the water pump components and the pump housing, making the installation difficult. Usually, after using a jig to cooperate with the pneumatic booster to install the water pipes in a certain direction, the water pipes in another direction are installed.

[0004] For example, a disclosed automotive water pump assembly mechanism in Chinese Patent CN219521183U uses a first clamping mechanism to clamp and limit the housing of the automotive water pump on a fixed seat, and then uses a second clamping component to clamp and limit the pulley in the automotive water pump parts on a first sliding seat, and then assembles the automotive water pump components with the automotive water pump.
