[0002] The pump volute is typically located outside the impeller. Its primary function is to collect the high-speed rotating liquid in the impeller and guide it out of the pump at a lower speed and higher pressure. In centrifugal pumps, the volute design is crucial for converting kinetic energy into static pressure energy, a process that helps improve pump efficiency and performance.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a CNC milling and positioning device for machining a pump volute, comprising a bracket 1, the top end of which is fixedly connected to a limiting assembly 2;

[0034] The limiting assembly 2 includes a mounting frame 21, both ends of which are fixedly connected to the bracket 1, a positioning plate 22 being fixedly connected to the interior of the mounting frame 21, a clamping column 23 being slidably connected to the interior of the positioning plate 22, one end of the clamping column 23 being fixedly connected to a damping telescopic column 24, an end of the damping telescopic column 24 away from the clamping column 23 being fixedly connected to an extension column 25, a pressure spring 26 being sleeved on the outer side of the damping telescopic column 24, and a pressure threaded column 27 being slidably connected to the interior of the positioning plate 22;

[0035] The bracket 1 is used to fix and support other components to ensure the stability and rigidity of the entire device. The mounting frame 21 is used to fix the positioning plate 22 and other components. The positioning plate 22 is used to fix and adjust the position of the clamping column 23 to adapt to workpieces of different sizes. The clamping column 23 is used to directly contact the workpiece and limit its position to ensure that the workpiece does not move during the processing. The damping telescopic column 24 is used to provide a damping effect when the clamping column 23 contacts the workpiece, reduce impact and vibration, and improve positioning accuracy. The extension column 25 is used to increase the length of the damping telescopic column 24, thereby adjusting the distance between the clamping column 23 and the workpiece to adapt to workpieces of different thicknesses. The pressure spring 26 is used to provide elastic force to maintain the contact pressure between the clamping column 23 and the workpiece to ensure the stability of the workpiece during processing. The pressure threaded column 27 is used to adjust the position of the positioning plate 22 by rotation, thereby fine-tuning the distance between the clamping column 23 and the workpiece to achieve more precise positioning;

[0036] like Figure 1 and Figure 3 As shown, the outer side of the bracket 1 is fixedly connected to a synchronous drive assembly 4, which includes a cylinder 41. The outer side of the cylinder 41 is mounted on the bracket 1. The driving end of the cylinder 41 is fixedly connected to a push plate 42. One side of the push plate 42 is fixedly connected to a push column 43. The end of the push column 43 away from the push plate 42 is rotatably connected to a rotating column 44. The outer side of the rotating column 44 contacts one end of the extension column 25.

[0037] The cylinder 41 provides linear motion power through its telescopic action, which is used to drive the push plate 42 and other connecting parts to perform corresponding actions. The push plate 42 converts the linear motion of the cylinder 41 into a thrust on the workpiece or other parts to achieve positioning or clamping of the workpiece. The push column 43 transmits the thrust of the push plate 42 to the rotating column 44 to achieve the pushing action on the extension column 25. The rotating column 44 pushes the extension column 25 under the push of the push column 43, thereby adjusting the position of the clamping column 23 to accommodate workpieces of different sizes.

[0038] like Figure 1 、 Figure 3 and Figure 4 As shown, the top of the bracket 1 is fixedly connected to a positioning assembly 3, which includes a motor 31. The outer side of the motor 31 is mounted on the bracket 1, and the driving end of the motor 31 is fixedly connected to a worm 32. The interior of the positioning plate 22 is rotatably connected to a worm gear 33. The worm 32 and the worm gear 33 are meshed. The internal thread of the worm gear 33 is connected to the outer side of the pressure threaded column 27. One end of the pressure threaded column 27 is fixedly connected to a push column 34. The outer side of the push column 34 is slidably connected to the interior of the positioning plate 22. One end of the pressure spring 26 is fixedly connected to the clamping column 23, and the other end of the pressure spring 26 is fixedly connected to the push column 34.

[0039] The motor 31 provides power through rotation to drive the worm 32 to rotate. The function of the worm 32 is to transmit the rotational motion of the motor 31 to the worm wheel 33 to drive the worm wheel 33. The worm wheel 33 is meshed with the worm 32. Its function is to convert the rotational motion of the worm 32 into its own rotational motion, and then to achieve rotational drive of the pressure threaded column 27 by being threadedly connected to the pressure threaded column 27. The pressure threaded column 27 is threadedly connected to the inside of the worm wheel 33, and converts the rotational motion of the worm wheel 33 into its own linear motion, thereby adjusting the position of the push column 34 to provide a pressure on the clamping column 23. The push column 34 transmits the linear motion of the pressure threaded column 27 to the clamping column 23 to adjust the position of the clamping column 23.

[0040] Working principle:

[0041] like Figure 1 - Figure 4 As shown:

[0042] During use: first place the pump volute on the bracket 1, then start the cylinder 41, the cylinder 41 pushes the push plate 42 and then drives the push column 43 to move synchronously, and under the push of the push column 43, the rotating column 44 will contact the extension column 25 and push, transmitting the power to the card column 23 to position the pump volute, and when the extension column 25 pushes the card column 23 to move, the pressure spring 26 will be pulled toward the card column 23, and then the motor 31 will be started again. When the motor 31 rotates, it will drive the worm 32 to rotate, and then the worm gear 33 rotates on the positioning plate 22. The rotation of the worm gear 33 will move the internal pressure threaded column 27 inward, and when moving, it will push the push column 34 to move toward the card column 23. At this time, the internal pressure spring 26 will be squeezed, applying pressure to the card column 23 to ensure stable positioning.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
