[0026] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0027] A high-speed CNC lathe for cutting a casting housing of a track traction motor includes a vehicle body 1 and a cutting assembly 2. The cutting assembly 2 is installed at the upper end of the vehicle body 1. The top end of the vehicle body 1 is fixedly connected with a working drive assembly 3. The inner side of the working drive assembly 3 is installed with a hydraulic flow assembly 4. The inner side of the hydraulic flow assembly 4 is fixedly connected with a clamping assembly 5. The working drive assembly 3 includes a machine box 31. An activity groove 32 is opened inside the machine box 31. A column 33 is fixedly connected inside the activity groove 32 opened in the machine box 31. The top end of the column 33 is fixedly connected with a placement table 34. A limit rotation groove 35 is opened inside the upper end of the machine box 31. The hydraulic flow assembly 4 includes a gear ring 41. A cylindrical column 42 is fixedly connected inside the machine box 31. A limit rotation ring 43 is fixedly connected to the outer side of the cylindrical column 42. An arm shell 44 is fixedly connected to the outer side of the cylindrical column 42. A hydraulic oil groove 47 is opened inside the arm shell 44. An electric telescopic rod 45 is fixedly connected to one side of the hydraulic oil groove 47 opened in the arm shell 44. A rubber column 46 is fixedly connected to one side of the electric telescopic rod 45. The clamping assembly 5 includes a metal hole shell 51. A double-column sliding rod 52 is slidably connected inside the metal hole shell 51. A sealing ring 53 is fixedly connected to the outer side of the double-column sliding rod 52. A spring 54 is fixedly connected to one side of the double-column sliding rod 52. An oil passage port 55 is opened inside one end of the metal hole shell 51. A solenoid valve 56 is fixedly connected inside the oil passage port 55 opened in the metal hole shell 51. The cylindrical column 42 is rotatably connected inside the limit rotation groove 35 opened in the machine box 31 through the limit rotation ring 43. One end of the outer side of the metal hole shell 51 is fixedly connected to the inside of the arm shell 44.

[0028] As a further implementation of this solution, the bottom end of the chassis 31 is fixedly connected to the top end of the vehicle body 1. The chassis 31 is in the shape of a hollow rectangular body. The active groove 32 is opened in the shape of a rectangular body. The active groove 32 communicates with the rotation-limiting groove 35. The rotation-limiting groove 35 is opened in the shape of three-section cylinders. The rotation-limiting groove 35 penetrates through the upper part of the chassis 31. The column 33 is inside the rotation-limiting groove 35. The placement table 34 is at the upper end of the chassis 31. The column 33 is in the shape of a cylinder. The cylindrical column 42 is sleeved outside the column 33. The cylindrical column 42 is in the shape of a hollow cylinder. The rotation-limiting ring 43 is in the shape of a ring, which facilitates the sleeving of the cylindrical column 42 outside the column 33 and plays a role in limiting the rotation of the cylindrical column 42 while not preventing the placement table 34 from supporting the casing of the track traction motor;

[0029] As a further implementation of this solution, a servo motor 36 is fixedly connected to the inner side of the active groove 32 opened in the chassis 31. The end of the main shaft of the servo motor 36 is fixedly connected to a gear 37. The gear 37 and the servo motor 36 are inside the active groove 32. The outside of the gear 37 meshes with the outside of the gear ring 41. After starting the servo motor 36, the cylindrical column 42 can rotate stably, so as to rotate the casing of the fixed track traction motor and adjust the cutting position;

[0030] As a further implementation of this solution, the lower part of the hydraulic oil groove 47 is opened in the shape of a cylinder. The rubber column 46 is in the shape of a cylinder. The outside of the rubber column 46 fits with the inner side of the hydraulic oil groove 47 opened in the arm shell 44. Hydraulic oil is provided inside the hydraulic oil groove 47. An installation hole is opened on the inner side of the arm shell 44 close to the clamping assembly 5, which facilitates the hydraulic oil inside the hydraulic oil groove 47 to enter the inside of the metal hole shell 51 respectively after starting the electric telescopic rod 45;

[0031] As a further implementation of this solution, the oil passage port 55 communicates with the hydraulic oil groove 47 opened in the arm shell 44. The number of the clamping assemblies 5 is several. The oil passage port 55 is in the shape of a hollow cylinder. The double-column slide rod 52 is in the shape of cylinders at both ends. A rubber ball 57 is fixedly connected to one side of the double-column slide rod 52. The outside of the sealing ring 53 fits with the inner side of the metal hole shell 51. One end of the spring 54 is fixedly connected to the inner side of the metal hole shell 51, achieving a stable fixing effect regardless of the shape of the casing, preventing the cutting assembly 2 from improving the stability of cutting the casing, and at the same time preventing damage to the casing during fixing.

[0032] Workflow: When the device is in use, it is powered by an external power supply. When it is necessary to fix the casing of the track traction motor, place the casing of the track traction motor above the placement table 34, and at the same time start two electric telescopic rods 45. The electric telescopic rods 45 drive the rubber columns 46 to move. The rubber columns 46 slide inside the hydraulic oil groove 47. The rubber columns 46 push the upper part of the hydraulic oil tank arm shell 44 on the inner side of the hydraulic oil groove 47 to move. At this time, all solenoid valves 56 are in the open state, and hydraulic oil enters the inside of the metal hole shell 51 from the oil passage port 55. Under the thrust of the hydraulic oil, the double-column slide rod 52 is pushed to move. The sealing ring 53 fixed on the outside of the double-column slide rod 52 plays a role in sealing between the metal hole shell 51 and the double-column slide rod 52. The double-column slide rod 52 drives the spring 54 fixed on one side to deform. Under the pulling force of the spring 54, the double-column slide rod 52 is kept inside the metal hole shell 51. When the rubber ball 57 fixed on one side of the double-column slide rod 52 contacts the casing of the track traction motor, the double-column slide rod 52 stops moving at this time. The rubber ball 57 that does not contact the casing of the track traction motor continues to move. When all the rubber balls 57 are closely attached to the outside of the casing of the track traction motor, start all the solenoid valves 56 to close the oil passage port 55. At this time, the length between the double-column slide rod 52 and the metal hole shell 51 is fixed. At this time, stop the electric telescopic rod 45 to complete the fixation of the casing of the track traction motor. Cut one side of the casing of the track traction motor through the cutting component 2. When one side of the casing of the track traction motor is cut, start the servo motor 36. The servo motor 36 drives the gear 37 to rotate. The gear 37 drives the outer meshing gear ring 41 to rotate. The gear ring 41 drives the cylinder column 42 to rotate. The cylinder column 42 is rotationally connected to the inner side of the limit rotation groove 35 opened in the chassis 31 through the limit rotation ring 43, which plays a role in limiting the rotation of the cylinder column 42. The cylinder column 42 drives the casing of the track traction motor to rotate through the arm shell 44 and the clamping component 5. After rotating 180 degrees, cut the other side of the casing of the track traction motor at this time. After cutting both sides, reset the electric telescopic rod 45 and the clamping component 5, and start the servo motor 36 again to drive the clamping component 5 to rotate. When the clamping component 5 rotates to the required angle, fix the casing of the track traction motor through the clamping component 5 again, and continue to cut the surface that has been cut multiple times.
