[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Machining the pump body in a CNC machining center typically requires drilling holes in the stop flange 81 and the outlet flange 85, and milling the base 83 of the pump body 8. When drilling holes in the stop flange 81, the tooling used to ensure machining stability obstructs part of the area to be machined, making it impossible to complete all holes in one go. The pump body 8 must be re-clamped midway to complete the remaining holes, which not only reduces machining efficiency but also introduces additional positioning errors due to the secondary clamping, thus affecting the final machining accuracy. When drilling holes in the outlet flange or milling the base is required, new tooling must be changed for clamping, further reducing the machining efficiency of the pump body. In this embodiment, a positioning plate 11 is provided on the stop positioning seat 1 to abut against the inner edge of the stop flange 81 of the pump body 8, and a pressure plate 2 is provided to abut against the inlet flange 82 of the pump body 8. The pressure plate 2 and the positioning plate 11 are clamped together by screws 3 to ensure the stability of the pump body 8 during machining. Furthermore, a clearance hole 12 is provided on the locating seat 1 to expose the drilling area of ​​the locating flange 81, enabling drilling of the locating flange 81 to be completed in one go. The tooling also has a locating side plate 6 and a locating post 7 to facilitate the clamping and positioning of the pump body 8 in one go, enabling drilling of the locating flange 81 and the outlet flange 85, as well as milling of the base 83 of the pump body 8, thereby improving the processing efficiency of the pump body 8.

[0018] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a pump body drilling and milling tooling of this utility model includes a stop positioning seat 1, a pressure plate 2, and a screw 3; the stop positioning seat 1 is used to support the pump body 8 from the side, the stop positioning seat 1 includes a positioning plate 11, the positioning plate 11 abuts against the inner ring edge of the stop flange 81 of the pump body 8, the stop positioning seat 1 is provided with a clearance hole 12 for exposing the drilling area of ​​the stop flange 81 of the pump body 8; the pressure plate 2 abuts against the water inlet flange 82 of the pump body 8; the screw 3 connects the pressure plate 2 to the positioning plate 11 through its own thread.

[0019] Working principle: A positioning plate 11 is provided on the locating seat 1 to abut against the inner edge of the locating flange 81 of the pump body 8, and a pressure plate 2 is provided to abut against the inlet flange 82 of the pump body 8. The pressure plate 2 and the positioning plate 11 are clamped to the pump body 8 by screws 3 to ensure the stability of the pump body 8 during processing. At the same time, an avoidance hole 12 is provided on the locating seat 1 to expose the area to be drilled in the locating flange 81, so that the drilling of the locating flange 81 can be completed in one go.

[0020] In some implementations, please refer to Figure 3As shown, the edge of the positioning disc 11 is provided with a clearance notch 111 corresponding to the drilling area of ​​the flange 81 of the pump body 8. The clearance notch 111 is used to ensure that the positioning disc 11 does not interfere with the cutting tool when drilling the flange 81.

[0021] In some embodiments, the positioning plate 11 is detachably mounted on the stop flange positioning seat 1. Detachable mounting of the positioning plate 11 allows for the adaptive replacement of positioning plates 11 of corresponding sizes for clamping and fixing when faced with different sizes of stop flanges 81, without the need to remove and replace the stop flange positioning seat 1 from the CNC center's workbench.

[0022] It is worth noting that, please refer to Figures 1 to 4 As shown, both the positioning plate 11 and the stop positioning seat 1 are provided with disassembly ports 4. After the tooling is released from clamping the pump body 8, the operator or lifting equipment can reach into the stop of the pump body 8 through the disassembly port 4 to grip the pump body 8, thereby quickly removing the pump body 8 from the tooling.

[0023] In some implementations, please refer to Figure 3 and Figure 4 As shown, the stop positioning seat 1 is provided with a weight reduction opening 13. The weight reduction opening 13 can reduce the weight of the stop positioning seat 1, so as to facilitate the tooling assembly onto the CNC center workbench.

[0024] In some implementations, please refer to Figure 2 and Figure 3 As shown, the screw 3 is equipped with an adjusting nut 31, which is used to drive the positioning plate 11 to clamp the pump body 8 with the pressure plate 2. By rotating the adjusting nut 31, the positioning plate 11 and the pressure plate 2 can be clamped together to achieve the desired clamping effect on the pump body 8.

[0025] It is worth noting that the pressure plate 2 can also be threaded onto the screw 3. By rotating the pressure plate 2, the distance between the positioning plate 11 and the pressure plate 2 can be adjusted to achieve the clamping of the pump body 8.

[0026] In some implementations, please refer to Figure 1 and Figure 2 As shown, the aforementioned pump body milling fixture also includes a positioning shaft 5 and two opposing positioning side plates 6. A positioning space is provided between the two positioning side plates 6 for the pump body 8's base 83 to enter. The positioning shaft 5 passes through the positioning side plates 6 and the ribs of the pump body 8's base 83. By having the positioning shaft 5 pass through the positioning side plates 6 and the ribs of the pump body 8's base 83, the pump body 8's base 83 is stably supported, enabling the CNC center to mill the bottom surface of the base 83.

[0027] In some implementations, please refer to Figure 5As shown, the positioning side plate 6 has a clearance angle 61 for exposing the drain hole area 84 of the pump body 8. The clearance angle 61 allows the CNC center to directly perform drain hole drilling operations on the pump body 8.

[0028] In some implementations, please refer to Figure 1 and Figure 5 As shown, the aforementioned pump body drilling and milling fixture also includes a positioning column 7, which is supported on the protruding rib on the back of the outlet flange 85 of the pump body 8. The positioning column 7 supports the outlet flange 85 of the pump body 8, enabling the CNC center to perform drilling operations on the outlet flange 85.

[0029] It is worth noting that, please refer to Figure 5 As shown, the positioning column 7 includes a pipe body 71 and a bolt 72. The inner wall of the pipe body 71 is provided with threads that are compatible with the bolt 72. The support height of the positioning column 7 can be adjusted by rotating the bolt 72 to accommodate various sizes of outlet flanges 85.
