[0037] The working principle of this utility model is as follows:

[0038] See Figures 5-8 As shown in the figure (where A represents the machine tool; B represents the workpiece; and C represents the device), during processing, the transmission mechanism 2 drives the loading / unloading mechanism 3 to move to the material-picking position. After the finger cylinder 311 drives the gripper 314 to pick up the material, the transmission mechanism 2 then drives the loading / unloading mechanism 3 to move to the machine tool gripper position. Specifically, as shown... Figure 6As shown, at this time, the workpiece is in the loading position; then the piston rod of the servo cylinder 321 extends, driving the electric suction cup 324 to move towards the workpiece through the buffer 323 and adsorb the workpiece. After adsorbing the workpiece, the finger cylinder 311 drives the gripper 314 to open, specifically as follows. Figure 7 As shown, at this point, the workpiece is in the suction position; then, the servo cylinder 321 continues to extend, conveying the workpiece into the machine tool gripper. After it is fixed in place, the electric chuck 324 releases its grip on the workpiece, as detailed below. Figure 8 As shown, at this point, the workpiece is in a fixed position; then, the piston rod of the servo cylinder 321 retracts, driving the electric suction cup 324 to reset to its initial position, as shown. Figure 9 As shown; then, the Z-axis guide rail assembly 22 drives the gripper assembly 31 and the loading / unloading assembly 32 to move upward through the fixed frame 4, and completely removes them from the machine tool, as shown. Figure 10 As shown; finally, the machine tool safety door is closed and processing begins.

[0039] Once one end of the workpiece is processed, the machine tool safety door opens, and the Z-axis guide rail assembly 22 drives the gripper assembly 31 and the loading / unloading assembly 32 to move down to the position via the fixed frame 4. Figure 9 The position is shown; then the piston rod of the servo cylinder 321 extends, driving the electric chuck 324 to move towards the workpiece through the buffer 323 and re-adsorb the workpiece, after which the machine tool grippers release the workpiece; then the piston rod of the servo cylinder 321 retracts, driving the workpiece to the position shown; Figure 7 The suction position is shown; then, the finger cylinder 311 drives the gripper 314 to re-grip the workpiece, and the electric suction cup 324 releases the suction from the workpiece; then, the piston rod of the servo cylinder 321 retracts, driving the electric suction cup 324 to return to the initial position, as shown. Figure 6 As shown; then the rotary cylinder 312 drives the finger cylinder 311 to rotate 180 degrees, thereby turning the workpiece.

[0040] After the workpiece has completed its rotation, it is re-clamped into the machine tool's jaws according to the above-described procedure. After machining the other end, the workpiece is removed from the machine tool again according to the above-described procedure, and jaws 314 re-clamp the workpiece. Figure 6 As shown, the specific process will not be repeated here.

[0041] After all processing is completed, the transmission mechanism 2 drives the loading and unloading mechanism 3 to move to the unloading position, places the workpiece, and completes one round of processing. Repeat the above steps until all processing is completed.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
