Description

Technical Field

[0001] The utility model relates to the field of tool processing, in particular to a combined forming milling cutter for simultaneously milling an inclined surface and a straight surface. Background Art

[0002] The setting of the water pump fixed coupling device can facilitate the maintenance of the water pump. During maintenance, the maintenance personnel do not need to go into the water to unscrew the screws, but can directly lift the water pump. After the maintenance is completed, they can go down along the guide rail to achieve a sealed connection between the water pump and the pipeline. Installation and maintenance are very convenient.

[0003] There are two main parts of the coupling device. One is the coupling elbow base that is fixed to the bottom of the pool and connected to the pipeline. The matching parts are a flat surface and an inclined surface with an angle of 105 degrees. The other is the bracket connected to the water pump. The matching parts are a flat surface and an inclined surface with an angle of 105 degrees. When the water pump slowly slides down the guide rail, the installation is completed when the matching parts of the bracket coincide with the matching parts of the coupling elbow base.

[0004] For the processing of inclined and straight surfaces on cast iron parts, the conventional processing method is to use different milling cutters to process different planes respectively, which requires secondary clamping, has low processing efficiency, large repeated positioning errors, and is difficult to ensure the accuracy of the angle, which will cause the processed coupling elbow base and the hook to get stuck after installation, and even cause the water pump to be unable to lift during maintenance. In view of this, this application is specially proposed. Utility Model Content
