A servo motor 12 is fixedly connected to the top of the base 1, and the output end of the servo motor 12 is fixedly connected with a driving gear 13.

[0029] Specifically: The clamping structure of this clamping and blanking device is that four clamping plates 14 clamp the workpiece simultaneously, so it is generally used for circular workpieces. The top of the protective shell 2 is open. One end of the rotating rod 10 extends to the outside of the protective shell 2 and is fixed to one side of the bottom of the top plate 3. The hydraulic cylinder 4 can adjust the clamping force according to actual needs to ensure an appropriate clamping effect even at different temperatures. The inner cavity of the sliding sleeve 7 slides on the surface of the sliding bar 6. The top of the sliding sleeve 7 slides inside the clamping plate 5, and the bottom slides outside the clamping plate 5, so as to drive the clamping plate 14 at the bottom of the sliding sleeve 7 to move through the driven rod 8. One end of the rotating rod 10 is rotatably connected to the bottom of the inner cavity of the protective shell 2 through a bearing. The servo motor 12 is located on one side of the top of the base 1 and does not contact the protective shell 2. Specific Embodiment Two

[0031] Please refer to Figures 1-5 , on the basis of Specific Embodiment One, the heat treatment part includes a clamping plate 14. The clamping plate 14 is fixedly connected to the bottom of the sliding sleeve 7. A spring 15 is fixedly connected to one side of the clamping plate 14. One end of the spring 15 is fixedly connected with a gasket 16. A bracket 17 is fixedly connected to the top of the clamping plate 14. A stepping motor 18 is fixedly connected to the top of the bracket 17. The output end of the stepping motor 18 is fixedly connected to the top of the disc 9 through a rotating shaft. An annular groove is opened on one side of the top of the base 1. One side of the bottom of the top plate 3 is fixedly connected with a support rod 19.

[0033] The working principle of the present utility model is as follows: When it is necessary to use this chuck automatic blanking device to blank a workpiece, first start the hydraulic cylinder 4 through an external controller. The hydraulic cylinder 4 drives the clamping disc 5 to move, so that the workpiece is located between the four clamping plates 14. Then start the stepping motor 18. The stepping motor 18 works to drive the disc 9 to rotate. Through the four arc grooves 20 in the inner cavity of the disc 9, the driven rod 8 slides inside it. The driven rod 8 drives the sliding sleeve 7 to slide on the surface of the slide bar 6. The sliding sleeve 7 drives the clamping plate 14 to move. The clamping plate 14 drives the gasket 16 at one end of the spring 15 to move. By moving the four clamping plates 14 simultaneously, the workpiece can be clamped, and the spring 15 and the gasket 16 can adapt to the thermal expansion of the workpiece, thereby improving the heat treatment performance of this chuck automatic blanking device.

[0034] After the workpiece is clamped, reverse-start the hydraulic cylinder 4 through the external controller, so that the workpiece moves upward to prevent the workpiece from being collided during transportation. Then start the servo motor 12. The servo motor 12 works to drive the driving gear 13 to rotate. The driving gear 13 drives the driven gear 11 to rotate. The driven gear 11 drives the rotating rod 10 to rotate. The rotating rod 10 drives the top plate 3 to rotate. The top plate 3 drives the workpiece clamped by the clamping structure to rotate to the working area. By reversing the stepping motor 18, the clamping plate 14 releases the limit on the workpiece and places it in the required working area, so as to automatically blank the workpiece.
