The shaft clamping groove 79 is V-shaped. Through the shaft clamping groove 79, when the cylinder 77 for clamping the shaft to be processed clamps the shaft to be processed and when the cylinder 78 for clamping the finished shaft clamps the finished shaft, the centering and axial level of the shaft can be achieved.

[0041] It is worth mentioning that in order to facilitate the processing of the rotating shaft by the clamping claw cylinder 77 in the rotating shaft feeding groove 25, a clamping avoidance groove 29 is provided on the side of the rotating shaft feeding seat 24.

[0042] Therefore, the cylinder 77 of the shaft to be processed in the double-station clamping mechanism 7 can clamp the shaft to be processed in the shaft loading seat 24, and the double-station clamping mechanism 7 clamps and moves the shaft to be processed to the conveying station of the workbench 21, and places the shaft to be processed on the second placement seat 63 of the duplex position material table 6.

[0043] Among them, after the processed shaft completes quenching in the quenching machine 1, the finished shaft will be placed on the first placement seat 62 of the duplex position material table 6 and transported out. At this time, the finished shaft clamping cylinder 78 of the duplex clamping mechanism 7 will clamp the finished shaft on the first placement seat 62, and the finished shaft will be moved from the first placement seat 62 to the finished material bin 23 through the duplex clamping mechanism 7.

[0044] Therefore, the duplex clamping mechanism 7 can realize one round-trip transport, whereby the shaft to be processed is moved from the shaft loading seat 24 to the duplex position material table 6, and the finished shaft is moved from the duplex position material table 6 to the finished product bin 23.

The shaft to be processed finger cylinder 83 is used to clamp the shaft to be processed on the double-station material table 6 and send it into the quenching machine 1, load the shaft to be processed through the pneumatic ejector mechanism 3, and perform the quenching process.

[0048] At the same time, the duplex loading mechanism 8 will move under the drive of the feeding robot 4, clamp the finished rotating shaft that has completed quenching on the quenching machine 1, and transfer it to the duplex position material table 6. The duplex position material table 6 transports the finished rotating shaft to the conveying station of the workbench 21 to facilitate the duplex clamping mechanism 7 to clamp the finished rotating shaft and add the rotating shaft to be processed to the duplex position material table 6.

[0049] Reference Figure 6 and Figure 7 As shown, the pneumatic ejector mechanism 3 includes a clamping frame 31, a lower ejector 32 rotatably mounted on the clamping frame 31, and an ejector clamping portion 33 disposed on the clamping frame 31. A driving motor 34 for driving the lower ejector 32 to rotate is disposed on the clamping frame 31, and a driving member for driving the clamping frame 31 to move in the vertical direction is disposed in the quenching machine 1.

[0051] In one embodiment, a thrust bearing 336 is disposed on the mounting seat 332 , and the upper ejector pin 334 is mounted on the thrust bearing 336 , thereby realizing a rotatable arrangement of the upper ejector pin 334 on the mounting seat 332 .

[0052] The ends of the lower ejector pin 32 of the upper ejector pin 334 are both provided with ejector pin cone ends to facilitate positioning of the two ends of the rotating shaft to be processed.

[0053] Thus, the double-station loading mechanism 8 moves the shaft to be processed between the upper ejector pin 334 and the lower ejector pin 32, and the upper ejector pin 334 moves downward under the drive of the ejector pin cylinder 333. The upper ejector pin 334 passes through the induction heating coil of the quenching machine 1 and abuts against the upper end of the shaft to be processed, and the lower ejector pin 32 abuts against the lower end of the shaft to be processed.

[0054] At this time, the hydraulic cylinder is driven to drive the clamping frame 31 to move, and the quenching position of the shaft to be processed is aligned with the induction heating coil of the quenching machine 1. The driving motor 34 drives the shaft to be processed to rotate, thereby completing the quenching process of the quenching machine 1. When the quenching of the shaft to be processed is completed, the double-station loading mechanism 8 will move under the drive of the feeding manipulator 4, clamp the finished shaft that has been quenched on the quenching machine 1, and transfer it to the double-station material table 6, and replenish the shaft to be processed to the ejector clamping part 33 for clamping and quenching.

[0055] To summarize, the present application uses a feeding robot 4 to replace manual labor to place the shaft to be processed into the quenching machine 1 for quenching processing, and takes out the finished shaft after quenching processing. The feeding and receiving mechanism 2 can realize the synchronous transportation and processing of the finished shaft and the shaft to be processed, thereby reducing the labor intensity of manual labor and improving the quenching efficiency of the shaft, with a high degree of automation.
