[0018] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] Embodiment 1:

[0020] like Figure 1-2As shown, a CNC vertical lathe vertical processing compound machine includes a box body a and a base 1 arranged in the box body a. A spindle 11 for driving a workpiece to rotate is arranged in the middle of the base 1. A three-jaw chuck 12 for fixing the workpiece is arranged on the upper end of the spindle 11. A column 2 is arranged on the base 1 corresponding to the side of the spindle 11. A crossbeam 21 that can be lifted and moved is arranged on the upper part of the column 2. A tool magazine 31 and a tool holder 41 are respectively arranged on the side walls of both ends of the crossbeam 21, and the tool magazine 31 is arranged on the crossbeam 21. It can move along the length direction of the beam 21 and move up and down. The tool holder 41 can move along the length direction of the beam 21 and move up and down on the beam 21. A first servo motor 12 is provided on the base 1 corresponding to the adjacent side of the main shaft 11. The first servo motor 12 is connected to the main shaft 11 through a bridge pulley 121. A rotary cylinder 13 coaxially arranged with the main shaft 11 is provided at the bottom of the base 1. The output shaft of the rotary cylinder 13 is coaxially connected with the bottom end of the main shaft 11, and an encoder 111 is provided at the bottom of the main shaft 11.

[0021] The above-mentioned three-jaw chuck, encoder, bridge pulley, rotary cylinder, tool magazine and tool holder are all products currently available on the market and are prior art, and will not be described in detail here. The above-mentioned main shaft is arranged in the middle of the base, and is synchronously connected to the first servo motor and the rotary cylinder. The upper end of the main shaft is connected to the three-jaw chuck, and the three-jaw chuck clamps the workpiece and fixes it. When driving the workpiece to rotate, the first servo motor drives the main shaft to rotate through the bridge pulley, thereby increasing the torque of the first servo motor. The rotary cylinder directly drives the main shaft to rotate, and the rotary drive of the main shaft by the rotary cylinder is accurately controlled by the encoder.

[0022] The servo motor has high precision and position control capabilities, and can achieve precise position control of the spindle. The rotary cylinder can provide a large torque output. The combination of the two can meet the high-precision motion control requirements of the spindle under different working conditions. The rotary cylinder can provide a large torque, especially in the startup and acceleration stages, and can quickly drive the spindle to overcome inertia and load. The servo motor can also maintain a stable torque output when running at high speed. The two work together to meet the spindle's torque requirements at different speeds, so that the spindle can adapt to different processing requirements, from low-speed fine processing to high-speed rough processing. In the continuous production process, even if the servo motor fails, the rotary cylinder can temporarily maintain the spindle operation to avoid production interruptions. At the same time, the two drives can share the load of the spindle, reduce the burden of a single drive, and extend the service life of the drive components.

[0023] like Figure 1-2As shown, a second servo motor 20 connected to the cross beam 21 through a screw structure is provided on the upper part of the column 2. When the second servo motor 20 is started, the cross beam 21 and the tool magazine 31 and the tool holder 41 connected to the cross beam 21 can be driven to move up and down. A first vertical ram 42 is provided at a position corresponding to the tool holder 41 on the cross beam 21. A third servo motor 43 is provided on the upper part of the first ram 42.

Next, a second vertically arranged slide 22 is provided on the crossbeam 21 corresponding to the position where the tool magazine 31 is located, a fourth servo motor 23 is provided on the upper part of the second slide 22, and the fourth servo motor 23 is transmission-connected to the tool magazine 31 arranged at the lower part of the second slide 22 through a screw structure arranged on the second slide 22, a fifth servo motor 24 is provided on the side of the second slide 22, and a drive shaft 25 is provided on the second slide 22, which is transmission-connected to the output shaft of the fifth servo motor 24 through a pulley structure, and the drive shaft 25 is transmission-connected to the tool magazine 31.

[0024] The screw rod structure in this embodiment is a matching structure of a conventional screw rod and a screw rod nut in the prior art, which converts rotational motion into linear motion. The output shaft of the second servo motor is connected to the screw rod structure, the second servo motor is fixed to the column, and the screw rod structure is connected to the crossbeam. When the second servo motor is started, the up and down movement of the crossbeam can be accurately controlled by the screw rod structure, so that the crossbeam drives the tool magazine and the tool holder to move up and down synchronously.

[0025] The output shafts of the third servo motor and the fourth servo motor are both transmission connected to the screw structure, the first slide and the second slide are fixed to the screw structure, the third servo motor and the fourth servo motor are respectively transmission connected to the tool magazine and the tool holder through the screw structure, when the third servo motor is started, the up and down movement of the tool holder can be accurately controlled by the screw structure; when the fourth servo motor is started, the up and down movement of the tool magazine can be accurately controlled by the screw structure, and at the same time, the fifth servo motor can accurately control the rotation of the drive shaft through the pulley structure, and the drive shaft is transmission connected to the tool magazine to control the high-speed rotation of the tool in the tool magazine.

[0026] like Figure 1-2As shown, a sixth servo motor 26 and a seventh servo motor 27 are arranged in parallel up and down on the transverse side of the beam 21. The sixth servo motor 26 is connected to the first slide 42 through a screw structure along the length direction of the beam 21, and the seventh servo motor 27 is connected to the second slide 42 through a screw structure along the length direction of the beam 21; the sixth servo motor and the seventh servo motor are fixed in parallel up and down at the edge of one side of the beam, and the output shafts of the sixth servo motor and the seventh servo motor are connected to the screw in the screw structure, and the screw in the screw structure is arranged along the length direction of the beam. The sixth servo motor drives the first slide through the screw structure, so that the first slide can drive the tool holder to move laterally along the length direction of the beam, and the seventh servo motor drives the second slide through the screw structure, so that the second slide can drive the tool magazine to move laterally along the length direction of the beam, so that the tool magazine and the tool holder can move laterally independently respectively.

[0027] Embodiment 2:

[0028] like Figure 3 As shown, an eighth servo motor 51 is provided on the side cover plate 5 of the front inner wall of the box body a, and the eighth servo motor 51 passes through the crossbeam 21 through a screw structure and is connected to the column 2, and the axial direction of the eighth servo motor 51 is perpendicular to the front end face of the crossbeam 21; the above-mentioned eighth servo motor is fixed to the inner side of the side cover plate of the front side wall of the box body, the output shaft of the eighth servo motor is connected to the screw structure, the screw end of the screw structure is rotatably connected to the column, and the axial direction of the eighth servo motor is perpendicular to the end face of the crossbeam.
