[0015] A method for using a CNC machine tool for machining a motor shaft of a new energy vehicle comprises the following steps: S1: When in use, according to the new energy vehicle motor shaft raw material that needs to be processed, turn the adjusting rod to adjust the position of the push rod, adjust the distance between the push rod and the chuck according to the length of the new energy vehicle motor shaft raw material, then align one end of the new energy vehicle motor shaft raw material with the cone head, and then fix the other end of the new energy vehicle motor shaft raw material in the chuck. During this process, the cone head will be pushed to one side to make the sliding rod slide inside the buffer groove. During the sliding process of the sliding rod, the tooth groove on the side wall of the sliding rod will engage with the intermittent gear to drive the intermittent gear to rotate, so that the connecting rod moves along with it, so that the splint at one end of the connecting rod can clamp the side wall of the new energy vehicle motor shaft raw material, which is used to assist the chuck in clamping the new energy vehicle motor shaft raw material, making the clamping more stable; S2: Install the corresponding cutter head inside the cutter seat. During the processing, the height of the cutter seat is adjusted by the electric push rod, and the position of the movable frame and the fixed seat is adjusted by the servo motor to process the raw materials of the motor shaft of new energy vehicles. During the process, the delivery pump can extract the liquid inside the liquid storage tank, and then deliver it to the delivery trough through the connecting pipe. Finally, it is sprayed out from the outlet pipe through the first corrugated telescopic pipe and sprayed on the processing position on the top of the cutter seat, so that the processed debris can be washed and fall on the fixed seat. Then, the ducted fan is used to exhaust the air, so that the liquid with debris falling on the fixed seat is pumped from the liquid inlet to the storage tank. Then, the liquid is blocked by the hydrophobic breathable membrane to prevent it from contacting the ducted fan. Finally, the liquid inside the storage tank flows into the liquid storage tank again through the circulation groove for processing. By arranging the circulation groove on the top of the filter plate, the liquid flowing out of the circulation groove can be cleaned by the filter plate, and the debris in the liquid is filtered by the filter plate. By arranging the water inlet pipe at the bottom of the filter plate, the liquid extracted by the water inlet pipe is all filtered clean liquid; S3: The surface treatment mechanism on the top of the movable frame can make it move with the movable frame, so that surface treatment can be performed between the processing parts. By setting a second support spring, it can be used to support the first mounting seat and the second mounting seat, so that when the mounting plate contacts the surface of the raw material of the new energy vehicle motor shaft during the processing, the mounting plate can fit the contact surface more closely, so that the grinding roller inside the mounting plate can perform better grinding treatment.

[0016] The present invention has at least the following beneficial effects: (1) This solution sets the surface treatment mechanism on the top of the movable frame so that it can move with the movable frame, so that surface treatment can be performed between the processing parts. The first support spring can be used to support the movable frame. The connecting shaft can be set so that the mounting plate can be movable on one side of the movable frame, so that the mounting plate can rotate according to the curvature of the surface of the new energy vehicle motor shaft raw material when it contacts the surface of the new energy vehicle motor shaft raw material during processing, so that the grinding roller of the mounting plate can be more closely fitted to the surface of the new energy vehicle motor shaft raw material during processing, so that the surface of the new energy vehicle motor shaft raw material can be processed while the new energy vehicle motor shaft raw material is being machined, thereby making the new energy vehicle motor shaft processing more efficient; (2) This solution sets up a chip removal and cleaning mechanism. By setting up a delivery pump, the liquid inside the liquid storage tank can be extracted, and then transported to the delivery trough through the connecting pipe. Finally, it is sprayed out from the outlet pipe through the first corrugated telescopic pipe and sprayed on the processing position on the top of the tool holder, so that the processed chips can be washed and fall on the fixed seat. Then, the ducted fan is used to exhaust air, so that the liquid with chips falling on the fixed seat is pumped from the liquid inlet to the storage tank. Then, the liquid is blocked by a hydrophobic breathable membrane to prevent it from contacting the ducted fan. Finally, the liquid inside the storage tank flows into the liquid storage tank again through the circulation groove for processing; (3) This scheme sets up an auxiliary clamping mechanism. One end of the new energy vehicle motor shaft raw material contacts the cone head, pushing the cone head to one side, so that the sliding rod slides inside the buffer groove. During the sliding process of the sliding rod, the tooth groove on the side wall of the sliding rod will engage with the intermittent gear to drive the intermittent gear to rotate, so that the connecting rod moves along with it, so that the splint at one end of the connecting rod can clamp the side wall of the new energy vehicle motor shaft, which is used to assist the chuck in clamping the new energy vehicle motor shaft raw material, making the clamping more stable; (4) This solution can be used to filter the liquid entering the liquid storage tank by setting a filter plate. By setting the flow slot on the top of the filter plate, the liquid flowing out of the flow slot can be cleaned by the filter plate, and the debris in the liquid can be filtered by the filter plate. By setting the water inlet pipe at the bottom of the filter plate, the liquid drawn by the water inlet pipe is all clean filtered liquid. BRIEF DESCRIPTION OF THE DRAWINGS

Then, one end of the new energy vehicle motor shaft raw material is aligned with the cone head 58, and the other end of the new energy vehicle motor shaft raw material is fixed in the chuck 101. During this process, the cone head 58 will be pushed to one side to make the sliding rod 57 slide inside the buffer groove 511. During the sliding process of the sliding rod 57, the tooth groove 571 on the side wall of the sliding rod 57 will engage with the intermittent gear 53 to drive the intermittent gear 53 to rotate, so that the connecting rod 54 moves together, so that the splint 56 at one end of the connecting rod 54 can be The side wall of the raw material of the new energy vehicle motor shaft can be clamped to assist the chuck 101 in clamping the raw material of the new energy vehicle motor shaft, making the clamping more stable. Then the corresponding cutter head is installed inside the cutter seat 401. During the processing, the height of the cutter seat 401 is adjusted by the electric push rod, and the position of the movable frame 3 and the fixed seat 4 is adjusted by the servo motor to process the raw material of the new energy vehicle motor shaft. During the process, the delivery pump 414 can extract the liquid from the liquid storage tank 2, and then deliver it to the delivery trough 412 through the connecting pipe 415.
