The plurality of clamping components 3821 release the finished product, and the grasping device 4 places the finished product into the blanking device 5. The safety box 6 is provided to prevent the finished product from slipping and affecting the operation of other devices.

[0042] Further, as Figures 1 - 2 shown, in this embodiment, the grasping device 4 includes: a manipulator 41, the manipulator 41 is connected to the fuselage 31 and is connected to the processing device 3. The manipulator 41 grabs the finished product and places it into the blanking device 5.

[0043] In use, the turntable 32 rotates to connect a gripper mechanism 34 with the feeding device 2. The cylinder 342 of the gripper mechanism 34 drives a pair of jaws 341 to open. The feeding device 2 conveys the bar stock 7 from the storage device 1 to the processing device 3. One end of the bar stock 7 is inserted between the pair of jaws 341. The cylinder 342 of the gripper mechanism 34 drives the pair of jaws 341 to close and clamp the bar stock 7. The transverse driving mechanism 363 of the automatic cutting unit 36 drives the cutting head 361 to move along the axial direction of the bar stock 7, thereby determining the cutting length of the bar stock 7. The longitudinal driving mechanism 364 drives the cutting head 361 to approach the bar stock 7 radially, and the second driving mechanism 362 drives the cutting head 361 to rotate. After cutting, a blank 71 is formed. The processing unit 35 corresponding to the clamped blank 71 performs primary processing on the blank 71. After the primary processing is completed, when the turntable 32 rotates, the blank 71 after the primary processing enters the next process. At this time, the gripper mechanism 34 that does not clamp the blank 71 is connected to the feeding device 2, and the feeding device 2 continues to convey the bar stock 7 forward, and then continues the previous actions until a bar stock 7 is processed, and then a new bar stock 7 is replaced. When one end of the blank 71 needs to be processed after drilling and threading by several processing units 35, the blank 71 is sent to the clamping replacement unit 37 through the rotation of the turntable 32. The third driving mechanism 372 drives the insertion rod 3711 and the first sleeve 3712 to move towards the processed end of the blank 71. The insertion rod 3711 is inserted into the hole processed in the blank 71, and the first sleeve 3712 is sleeved on the blank 71. At this time, the jaws 341 are loosened, and the third driving mechanism 372 pushes the other end of the blank 71 away from the jaws 341 through the insertion rod 3711 and the sleeve, and the jaws 341 close to clamp the blank 71, and the other processing unit 35 processes the other end of the blank 71. The last process of the blank 71 is turning the outer circle, which is completed by the turning unit 38. The fourth driving mechanism drives several clamping components 3821 to open. The sixth driving mechanism 3824 and the seventh driving mechanism 3825 are driving mechanisms in the X and Y axis directions respectively, driving several clamping components 3821 to approach the blank 71. The fourth driving mechanism drives several clamping components 3821 to clamp the blank 71. Then, the sixth driving mechanism and the seventh driving mechanism 3825 drive the clamping components 3821 to drive the blank 71 to approach the turning tool 381. The fourth driving mechanism drives several clamping components 3821 to rotate, and at the same time drives the blank 71 to rotate, and starts turning processing. After the processing is completed, a finished product is formed. The turning power module 382 and the grasping device 4 cooperate to enable the grasping device 4 to grasp the finished product and place it on the blanking device 5.
