[0003] When producing mechanical tees for fire protection pipes, the surface of the casting needs to be fine-machined to form the required dimensional accuracy, surface roughness and clamp notches. The existing machining process equipment uses a structure with a middle hole and curved surfaces on both sides as a fixing device for the mechanical tee, which is placed on a machine tool for processing with a turning tool. Due to the large size deviation of the casting, this process equipment cannot accurately position the mechanical tee through the middle hole, and the processed size is easily eccentric, resulting in product scrapping. The product needs to be rotated to find the fixed center for the tool tip, which increases the processing time.
