Figure 1-3 A CNC lathe lifting device comprises a device body 1, an adjusting mechanism 2 is arranged on the device body 1, the adjusting mechanism 2 comprises a motor 21, an output end of the motor 21 is fixedly connected with a first transmission wheel 22, an outer side of the first transmission wheel 22 is rotatably connected with a transmission belt 23, an inner side of the transmission belt 23 is rotatably connected with a second transmission wheel 24, a spline shaft 25 is arranged on the inner side of the second transmission wheel 24, a top of the spline shaft 25 is fixedly connected with a placing plate 26, a bottom of the spline shaft 25 is rotatably connected with a connecting pipe 29, a mounting plate 28 is installed at the bottom of the connecting pipe 29, and a cylinder 27 is fixedly connected with the top of the mounting plate 28;

[0021] When the position of the workpiece on the placement plate 26 needs to be adjusted, it is only necessary to start the cylinder 27 installed on the inner side of the second limit frame 14. When the cylinder 27 moves downward, the cylinder 27 drives the mounting plate 28 to move downward. When the mounting plate 28 moves downward, the mounting plate 28 drives the connecting pipe 29, the spline shaft 25, and the placement plate 26 to move downward in turn, thereby adjusting the upper and lower heights of the top workpiece.

[0022] The output signal of the encoder is compared with the input signal of the motor 21 driver through the rotary encoder. When the motor 21 rotates, the motor 21 drives the first transmission wheel 22 installed at the output end to rotate. When the first transmission wheel 22 rotates, the first transmission wheel 22 drives the second transmission wheel 24, the spline shaft 25, and the placement plate 26 to rotate in turn, thereby adjusting the angle of the workpiece set above.

[0026] Reference Figure 1-3The first transmission wheel 22 and the second transmission wheel 24 are installed at the bottom of the connecting plate 12 through bearings; when the motor 21 rotates, the motor 21 drives the first transmission wheel 22-transmission belt 23-second transmission wheel 24 in sequence to ensure the smooth operation of the device.

[0027] The implementation principle of a CNC lathe lifting device in an embodiment of the present application is as follows: when it is necessary to adjust the position of a workpiece installed on a placement plate 26, a staff member compares the output signal of the encoder with the input signal of the motor 21 driver through a rotary encoder. When the motor 21 rotates, the motor 21 drives the first transmission wheel 22 installed at the output end to rotate. When the first transmission wheel 22 rotates, the first transmission wheel 22 sequentially drives the second transmission wheel 24, the spline shaft 25, and the placement plate 26 to rotate, thereby adjusting the angle of the workpiece set above, without the need for manual angle adjustment, thereby improving the convenience of angle adjustment and the accuracy of position control.
