[0001] The utility model relates to the technical field of positioning tools, in particular to a positioning tool for machining a rotor pump body flange. Background Technique

[0002] The rotor pump body flange is a key part in the rotor pump. It specifically refers to the flange structure installed on the rotor pump body. Its main part is a disc-shaped structure for docking with the flange of a pipeline or other equipment. Bolt holes are distributed on the disc-shaped structure for installing bolts. Through the bolt holes and bolts, the connection between the pump body and the pipeline or other equipment is realized. Before machining the rotor pump body flange, it is usually necessary to first place the rotor pump body on a positioning tool for clamping and precise positioning, so as to ensure the accurate position of the rotor pump body flange during the machining process, thereby improving the machining accuracy and product quality of the rotor pump body flange. However, due to the unique structure and heavy weight of the rotor pump body, it is difficult to install and the positioning is inaccurate when using a common positioning tool, resulting in a low yield rate of the rotor pump body flange. The specific structure of the rotor pump body is as Figure 4 shown. Content of the Utility Model

[0044] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0045] In view of the current situation that due to the unique structure and excessive weight of the rotor pump body 8, it is difficult to install and position accurately when using ordinary positioning tooling, resulting in a low yield rate of the rotor pump body flange 81. The embodiment of the present utility model provides a processing and positioning tooling for the rotor pump body flange, as Figures 1 - 4 shown, including: a bottom plate 1, a base 2, an installation guide, a positioning guide, a clamping assembly and other parts.

[0046] Among them, a base 2 is provided on the bottom plate 1, and an installation guide is provided on the base 2. The installation guide is located in the vertical direction of the base 2. The installation guide ensures that the rotor pump body 8 maintains a stable movement trajectory during the installation process, preventing deviation or jitter. The positioning guide is provided on the bottom plate 1 and is located around the base 2. The positioning guide is in direct contact with the bottom of the rotor pump body 8, and the precise positioning of the rotor pump body 8 relative to the base 2 is achieved through the positioning guide. The clamping assembly is provided on the base 2, and the position locking of the rotor pump body 8 after positioning is achieved through the clamping assembly, preventing the rotor pump body flange 81 from moving or swinging during the processing, ensuring the processing accuracy and stability of the rotor pump body flange 81, and improving the yield rate of the rotor pump body flange 81.

[0047] Specifically, the base 2 serves as a main bearing body to carry other components. The shape of the base 2 is basically the same as that of the rotor pump body 8, improving the adaptability between the rotor pump body 8 and the base 2, enabling the rotor pump body 8 to be more easily and quickly installed on the base 2. Its size is slightly smaller than that of the rotor pump body 8.

[0048] Such as Figure 2 and Figure 3 As shown, in this embodiment, the installation guides are several tapered guide columns 3, which are spaced apart and arranged at the edge of the top of the base 2. The tapered guide column 3 specifically includes a tapered guide column body 31 and a screw 32. The screw 32 is integrally formed at the bottom of the tapered guide column body 31, and the tapered guide column body 31 is threadedly connected to the base 2 through the screw 32. The tapered guide column 3 provides precise guiding and positioning functions for the installation of the rotor pump body 8. More specifically, in this embodiment, there are 4 guide columns 3, which are respectively fixedly arranged opposite to each other at the edge of the base 2.

[0049] Such as Figure 2 As shown, the positioning guides can be several universal balls 4. Preferably, in this embodiment, the positioning guides are 4 universal balls 4, which are respectively arranged opposite to each other on the bottom plate 1 adjacent to the base 2. The sliding of the rotor pump body 8 relative to the bottom plate 1 is realized through the rolling of the universal balls 4, and then the precise positioning of the rotor pump body 8 relative to the base 2 is realized.

[0050] Furthermore, the positioning and processing tooling for the rotor pump body flange further includes a tapered clamping member 6, which is arranged on a gasket 9 located on the central axis of the base 2. A threaded hole is opened at the exact middle position of the clamping member 6, and an internal hexagonal screw is placed in the threaded hole. The clamping member 6 can move up and down under the action of the internal hexagonal screw, that is, when the internal hexagonal screw acts on the threaded hole of the clamping member 6, the clamping member 6 moves downward, and when the internal hexagonal screw is loosened, the clamping member 6 automatically resets.

[0051] Even further, as Figure 1As shown in the figure, the clamping assembly specifically includes a pressing block 51, a double-headed stud 52, and a fixing plate 53. Among them, the pressing block 51 is in a "T" shape. The pressing block 51 is symmetrically and movably arranged on the top of the base 2 with the clamping member 6 as the center. The end face of the pressing block 51 is adapted to the inner side wall of the rotor pump body 8. By moving the pressing block 51, the end face of the pressing block 51 is abutted against the inner wall of the rotor pump body 8, so as to realize the fixing effect of the pressing block 51 on the rotor pump body 8; the double-headed studs 52 are oppositely arranged on the base 2 and are respectively located on both sides of the pressing block 51 to fix and lock the position of the pressing block 51; the fixing plate 53 is arranged at one end of the double-headed stud 52 and is connected to the double-headed stud 52 by threads.

[0052] During use, first, the rotor pump body 8 is installed on the bottom plate 1 under the guidance of the tapered guide post 3. The bottom of the rotor pump body 8 abuts against the universal ball 4 arranged on the bottom plate 1. Under the action of the universal ball 4, the rotor pump body 8 is accurately positioned relative to the base 2. After the rotor pump body 8 is positioned, an inner hexagon screw is used to act on the clamping member 6 to make the clamping member 6 move downward. During the downward movement of the clamping member 6, the clamping member 6 presses the pressing block 51, and the pressing block 51 moves until the end face of the pressing block 51 abuts against the inner side wall of the rotor pump body 8. Then, the double-headed stud 52 is used to fix and lock the position of the pressing block 51. Finally, the position of the rotor pump body 8 after positioning is locked through the fixing plate 53.

[0053] Furthermore, as Figure 1 shown in the figure, in order to prevent the pressing block 51 from detaching from the top of the base 2 during the movement, a stop block 7 is fixedly arranged at the relative position on the top of the base 2, and the stop block 7 corresponds to the center position of the end face of the pressing block 51.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
