The beneficial effects of the invention are as follows:

because the feeding position of the manipulator is far away from the feeding position of the spindle nose of the numerical control machine tool, if the feeding position is only extended by the air cylinder, the difficulty is high, and the air cylinder and the steering structure are both subjected to a large test, in the process of feeding the small-volume valve core, firstly, an unprocessed workpiece on the storage seat is clamped by the transfer structure, the transfer structure is moved to the opening at the top of the numerical control machine tool through the matching of the sliding frame and the guide rail, the overturning structure overturns and the transversely-moving push rod motor retracts, the top baffle plate does not shield the top surface of the numerical control machine tool any more, the transfer structure can extend into the numerical control machine tool and convey the workpiece to the position of the feeding area corresponding to the spindle nose by the guide pipe, and the guide pipe can bear the workpiece on the transfer structure through the arrangement of the guide pipe, so that the transfer structure does not need to go deep into the numerical control machine tool, the movable stroke of the transfer structure is reduced, and the damage in the extending process or the reversing process of a long stroke is avoided.

However, in the process of using, although the material guiding pipe can bear a workpiece, in the normal workpiece turning stage, if the material guiding pipe is positioned in the numerical control machine tool, the normal movement of a tool turret or a tool apron of the numerical control machine tool is influenced, so the invention further provides a turnover structure, the material guiding pipe is connected to a connecting cylinder of a swinging motor, when the workpiece needs to be fed, the material guiding pipe is directly swung down and corresponds to a shaft head, the feeding can be smoothly carried out, after the feeding action is finished, the transfer structure is firstly retracted, and then a transposition cylinder is pushed out again, so that the top baffle is re-covered on the top of the numerical control machine tool, and meanwhile, the material guiding pipe is rotated to be parallel to the top baffle, so that the material guiding pipe does not occupy the space in the numerical control machine tool after the feeding is finished, and can reach a designated position when the workpiece needs to be used.

The guide pipe and the turnover structure are in a linkage state, if the guide pipe is not turned down at any time after the turnover structure is retracted, mechanical interference can be caused, or the air cylinder is damaged or the mechanical structure is deformed, so that the swing motor is further electrically connected with the transverse push rod motor, and the transverse push rod motor is retracted only after the swing motor starts to turn down, so that favorable circulation can be formed, and the guide pipe is retracted after turning down and pushed out when being lifted up.

The workpiece entering the material guide pipe can slide downwards along the containing pipe in the material guide pipe, however, if the workpiece is not shielded, the falling workpiece is possibly caused to deviate in position or directly fall out of the containing pipe, and therefore, the invention further provides that the bottom of the swinging frame is provided with the temporary shielding piece, and the discharging end of the material guide pipe can be completely sealed by the temporary shielding piece in the falling stage, so that the workpiece can not directly fall out of the containing pipe when sliding downwards, and in the feeding stage, the workpiece is directly pushed into the position of the shaft head through the punching cylinder, and the shaft head is clamped again, so that the workpiece is limited without influencing normal feeding actions.
