The CNC grinder uses a grinding wheel assembly consisting of a servo motor and a grinding disc connected to the output shaft of the servo motor, and the servo motor includes at least two different output speeds, which match the different materials of the shaft. Different output speeds can be used to grind the shaft according to the different materials of the shaft, and the outer diameter of the shaft is detected by the detection component. When it is detected that the outer diameter of the shaft reaches the target requirement, feedback is given to the controller, and the controller controls the servo motor to stop grinding. The use of a servo motor with high control accuracy and high stability is conducive to improving the control of grinding accuracy. Through the improved combination of the above-mentioned multiple structures, the processing accuracy of the water pump rotor is improved as a whole, the product quality of the water pump rotor is improved, and it is also conducive to mass production. Specifically, using a water pump rotor digital processing device provided by the present invention, the processing time of a single water pump rotor can be shortened to 43 seconds, greatly improving the processing efficiency.

[0018] Furthermore, it also includes a special machine arranged at the rear end of the second CNC lathe along the processing sequence, and the special machine is used to drill and tap one end face of the rotating shaft of the water pump rotor processed by the second CNC lathe and mill a straight groove on the other end face.

[0026] Furthermore, the correction mechanism includes a first jaw and a second jaw that can be opened and closed, the first jaw is located above the second jaw, the inner wall of the first jaw is provided with a first limiting groove that is adapted to the outer diameter of the rotating shaft, and the inner wall of the second jaw is provided with a second limiting groove that is adapted to the outer diameter of the water pump rotor.

[0027] From the above description, it can be seen that through the above structural design, the water pump rotor and the rotating shaft can be corrected and aligned to facilitate force balance during the subsequent downward pressure process. By setting the first limit groove and the second limit groove, the accuracy of the correction and alignment can be ensured.

[0028] Furthermore, a second drive motor is provided below the turntable, and an output shaft of the second drive motor is drivingly connected to a central position of the lower end of the turntable.

[0044] The CNC grinder 5 is used to grind the bearing block and stainless steel section of the water pump rotor after the press processing; The CNC grinder 5 includes a rotatable third clamping assembly 51 and a grinding wheel assembly 52 and a detection assembly 53 respectively arranged on both sides of the third clamping assembly 51. The third clamping assembly 51 includes two clamping parts 511 arranged opposite to each other and clamping a rotating shaft together. The clamping part 511 is a conical top joint, which is installed on a mounting part that can rotate along a vertical plane. Through this structural design, the top connection of the rotating shaft is realized, and rotation along a vertical plane can be realized.

[0045] The rotating shaft includes two different materials, and the grinding wheel assembly 52 includes a servo motor 521 and a grinding disc 522 connected to the output shaft of the servo motor. The servo motor 521 includes two different output speeds and matches the different materials of the rotating shaft; the grinding wheel assembly 52 also includes a detection rod 523 and an angle measuring device for measuring the inclination angle of the detection rod. One end of the detection rod 523 is overlapped on the grinding disc 522, and the wear degree of the grinding disc is detected by matching the detection rod and the angle measuring device, which is convenient for timely replacement or maintenance. In this embodiment, the number of the detection rods 523 is three, and they are respectively set to the position close to one side end face, the middle position and the position close to the other side end face of the grinding disc. The three detection rods can correspond to the position close to one side end face, the middle position and the position close to the other side end face of the grinding disc, that is, to achieve detection of different positions and ensure the grinding processing accuracy.

[0046] The grinding wheel assembly 52 further includes a moving mechanism 524, and the servo motor 521 is mounted on the moving mechanism 524. Through this structural design, the servo motor and the grinding disc can move synchronously. The moving mechanism 524 can adopt an existing mechanical structure.

[0047] The detection assembly 53 is mounted on the cylinder assembly 531, and the movement direction of the cylinder assembly 531 is toward the clamping position of the rotating shaft. The position of the detection assembly can be adjusted through the cylinder assembly, and it can be applicable to rotating shafts of different sizes. The detection assembly 53 is used to detect the outer diameter of the rotating shaft. Specifically, the existing product structure can be adopted, that is, there is a spring inside, and the spring enables the two top parts 532 on the outside to be close to the surface of the rotating shaft. When the diameter of the rotating shaft is polished and reduced, under the action of the spring, the distance between the two top parts is also synchronously reduced. At this time, the reduced value can be detected, and it can be determined whether the required diameter parameter is polished. The detection assembly and the servo motor are electrically connected to the controller of the peripheral device respectively. That is, when it is detected that the outer diameter of the rotating shaft reaches the target requirement, feedback is given to the controller, and the controller controls the servo motor to stop polishing.

[0048] There are two detection components 53, and the two detection components 53 are respectively arranged corresponding to the two different material positions of the rotating shaft. Using two detection components to detect the two different material positions of the rotating shaft respectively can improve the processing efficiency, and only the grinding disc needs to be moved.
