[0021] Due to the angle of the drawing, some parts may not be drawn, but their positions and connections can be understood from the text descriptions.

[0022] like Figure 1 As shown, this utility model is an electronic oil pump assembly tooling, including a housing positioning plate 3, on which an oil pump pressing structure and a housing positioning mechanism are provided.

[0023] The oil pump pressing structure includes a pressing handle 1-1, one end of which is hinged to the upper part of the housing positioning plate 3. A pressing slider 1-2 is slidably mounted on the pressing handle 1-1, and the lower part of the pressing slider 1-2 is hinged to the pressing cap connecting block 1-3. The lower part of the pressing cap connecting block 1-3 is fixedly connected to the electric pump pressing cap 1-4. The electric pump pressing cap 1-4 has an electric pump positioning groove 1-41.

[0024] Specifically, the pressing handle 1-1 has a groove in which the pressing slider 1-2 slides. The lower part of the pressing slider 1-2 is hinged to the pressing cap connecting block 1-3 via a pin 1-5. The lower part of the pressing cap connecting block 1-3 is fixedly connected to the electric pump pressing cap 1-4 via bolts.

[0025] The housing positioning mechanism includes a housing main positioning plate 2-1 and a housing support block 2-2. The housing main positioning plate 2-1 is installed in the middle of the housing positioning plate 3, and the housing support block 2-2 is installed in the lower part of the housing positioning plate 3.

[0026] The main positioning plate 2-1 of the housing has a main positioning notch 2-11 on its side. In order not to scratch the housing flange surface, a housing positioning pad 2-3 is installed on the top of the main positioning plate 2-1 of the housing. The housing positioning pad 2-3 also has a second housing positioning notch 2-31.

[0027] The main positioning plate 2-1 of the housing is bolted to the middle of the housing positioning plate 3. The housing positioning pad 2-3 is bolted to the top of the main positioning plate 2-1. To enhance the supporting strength of the main positioning plate 2-1, a reinforcing rib 2-4 is installed between the bottom of the main positioning plate 2-1 and the housing positioning plate 3.

[0028] To facilitate gripping of the housing positioning plate 3, a handle 4 is installed on the outside of the housing positioning plate 3.

[0029] The working process of this utility model is as follows:

[0030] The operator simply needs to insert the electric drive housing into the housing positioning mechanism. Then, place the electric oil pump into the electric drive housing, and then align the electric pump cap 1-4 with the electric oil pump by pressing down the pressing handle 1-1, and press it in normally.

[0031] By precisely matching the conformal pressure cap and the oil pump, the oil pump can be pressed into the electric drive housing by applying positive pressure through the handle. During the pressing process, the handle slider can adjust the radial displacement of the pressure cap connecting blocks 1-3 to achieve the vertical force state of the oil pump.

[0032] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
