[0002] In the field of pump casing processing, tapping is a key step to achieve precise connection between pump casing and mechanical parts. Traditional pump casing tapping tooling has many limitations, which are mainly manifested in the following aspects:

[0003] Insufficient positioning accuracy: The positioning mechanism of existing tooling is usually relatively simple and cannot achieve accurate positioning of the pump casing body, which leads to errors in the tapping process.

[0004] Low operating efficiency: Due to the lack of an effective adjustment mechanism, the operator needs to manually perform multiple fine-tuning when adjusting the tooling, which is not only time-consuming but also increases the complexity of the operation.

[0005] Poor stability: During the tapping process, the pump housing is prone to vibration or displacement due to unstable support, affecting the processing quality.

[0006] Insufficient durability: The connecting parts of existing tooling are prone to wear or damage, requiring frequent maintenance or replacement, which increases the cost of use.

[0007] Poor adjustment flexibility: Existing tooling is difficult to adapt to pump casings of different specifications or shapes, limiting its scope of application.

[0008] Safety issues: If the tooling design is unreasonable, there may be safety hazards, such as loose or broken parts, which may cause potential harm to operators. For this reason, we provide a fixed tooling for pump casing tapping. Utility Model Content
