The surface has through holes and is rotatably connected to the left support plate of the frame 1. An adjusting block 9 is laterally slidably connected between the outer arc surfaces of the two guide columns of the frame 1. The screw hole in the middle of the adjusting block 9 is connected to the screw thread of the screw motor 8. An electric push rod 10 is provided at the rear end of the slide groove at the upper end of the adjusting block 9. The front end of the telescopic end of the electric push rod 10 is fixedly connected to the adjusting slide plate on the outer arc surface of the mounting shell 2. The adjusting slide plate on the outer arc surface of the mounting shell 2 is longitudinally slidably connected in the slide groove at the upper end of the adjusting block 9. The input ends of the screw motor 8 and the electric push rod 10 are both electrically connected to the output end of the PLC controller 7. When the screw motor 8 is started, the screw of the screw motor 8 rotates. Through the screw thread of the screw and the screw hole in the middle of the adjusting block 9, the adjusting block 9 is driven to move laterally on the outer arc surface of the guide column of the frame 1 to adjust the left and right positions of the slotted head 4. When the electric push rod 10 is started, the electric push rod 10 pushes the adjusting slide plate on the outer arc surface of the mounting shell 2 to slide longitudinally in the slide groove at the upper end of the adjusting block 9 to adjust the front and rear positions of the slotted head 4. It also includes a cooling mechanism 5.

[0021] Cooling mechanism 5 includes a centrifuge shell 51, an inlet pipe 52, an impeller 53, and an outlet pipe 54. The centrifuge shell 51 is located in the middle of the mounting shell 2. The inlet pipe 52 is located at the inlet on the middle of the right side of the centrifuge shell 51. The impeller 53 is rotatably connected to the middle of the left inner wall of the centrifuge shell 51 via a rotating shaft. The impeller 53 is connected to the drive shaft 3. The outlet pipe 54 is located at the outlet at the lower end of the outer arc surface of the centrifuge shell 51. The cooling mechanism 5 also includes a worm gear 57 and a worm wheel 58. 7 is located in the middle of the outer arc surface of the drive shaft 3, and the worm gear 58 is located at the left end of the impeller 53's rotating shaft. The worm gear 58 is meshed with the worm 57. During the grooving process, the rotation of the drive shaft 3 will drive the worm 57 to rotate. Through the meshing connection between the worm 57 and the worm gear 58, the worm gear 58 drives the impeller 53 to rotate. Using the centrifugal force generated by the rotation of the impeller 53, the external coolant enters the centrifuge shell 51 through the inlet pipe 52, and then flows into the rotating tank 5 through the outlet pipe 54. Inside the 9th cavity, the coolant is finally sprayed out from the nozzle 56. The amount of coolant sprayed out varies with the rotation speed of the slotted head 4, ensuring the cooling effect while reducing coolant waste. The cooling mechanism 5 also includes a rotating ring 55, a nozzle 56, and a rotating groove 59. The rotating groove 59 is located on the front surface of the mounting shell 2 and is connected to the front end of the outlet pipe 54. The rotating ring 55 is rotatably connected inside the rotating groove 59. The nozzles 56 are installed in the mounting holes distributed in a ring on the front surface of the rotating ring 55 to guide the trajectory of the coolant spray. The inner and outer arc surfaces of the rotating ring 55 are rotatably connected to the inner wall of the rotating groove 59 through sealed bearings to prevent coolant leakage from the gap between the rotating ring 55 and the rotating groove 59. The front end of the inner arc surface of the rotating ring 55 is fixedly connected to the outer arc surface of the drive shaft 3. During the coolant spraying process, the drive shaft 3 will drive the rotating ring 55 to rotate, so that the coolant sprayed from the nozzle 56 forms a water curtain around the slotted head 4, preventing debris generated during the slotting process from splashing outward.

[0022] The working principle of the valve sleeve positioning groove grooving device provided by this utility model is as follows: When grooving the valve sleeve positioning groove, the drive motor 6 is started by the PLC controller 7. The output shaft of the drive motor 6 drives the transmission shaft 3 and the grooving head 4 to rotate. At the same time, the lead screw motor 8 is started. The lead screw of the lead screw motor 8 rotates, and through the thread of the screw and the screw hole in the middle of the adjusting block 9, it drives the adjusting block 9 to move laterally on the outer arc surface of the guide column of the frame 1, thereby adjusting the left and right position of the grooving head 4. The electric push rod 10 is started. The electric push rod 10 pushes the adjusting slide plate on the outer arc surface of the mounting shell 2 to slide longitudinally in the slide groove at the upper end of the adjusting block 9, thereby adjusting the front and rear position of the grooving head 4, so that the high-speed rotating grooving head 4 contacts the valve sleeve. A positioning groove is cut on the surface of the valve sleeve. During the grooving process, the rotation of the drive shaft 3 will drive the worm 57 to rotate. Through the meshing connection between the worm 57 and the worm wheel 58, the worm wheel 58 drives the impeller 53 to rotate. Using the centrifugal force generated by the rotation of the impeller 53, the external coolant enters the centrifugal shell 51 through the inlet pipe 52, and then flows into the rotating trough 59 through the outlet pipe 54. Finally, it is sprayed out from the nozzle 56. The amount of coolant discharged varies with the rotation speed of the grooving head 4. While ensuring the cooling effect, the waste of coolant is reduced. At the same time, the drive shaft 3 will drive the rotating ring 55 to rotate, so that the coolant sprayed from the nozzle 56 forms a water curtain around the grooving head 4, preventing the debris generated during the grooving process from splashing outward.

[0023] It is worth noting that the PLC controller 7 disclosed in the above embodiments can be an NX7 model PLC controller, and the drive motor 6, lead screw motor 8 and electric actuator 10 can be freely configured according to the actual application scenario. The drive motor 6 can be a 5IK40RGU-CF model motor, the lead screw motor 8 can be a 28E245-6.35-115 model lead screw motor, and the electric actuator 10 can be an ANT-52 model electric actuator.
