[0047] Principle of the present invention: The state of the material-removing workpiece 6 at the upper end of the quenching station (the state of the material-removing workpiece away from the loading station) is to place the workpiece at the quenching station at this time: the driving motor 22 is started, and the threaded rod 24 is driven to rotate through the pulley mechanism 23, thereby driving the upper cross plate 25 threadedly connected to the threaded rod 24 to move downward, and the lower cross plate 26 is driven to move downward under the extrusion force of the spring 31, so that the clamping head 47 moves downward, the lower cross plate 26 contacts the quenching station, and the lower end face of the clamping head 47 contacts the upper end face of the object placement seat 2 18, and the upper cross plate 25 continues to move downward, thereby the fixed column 37 moves downward, thereby the support rod 39 moves downward, so that the rotating plate 2 57 rotates, and the support rod When 39 continues to move downward to the bottom of the placement slot three 53, the rotating plate two 57 repels under the action of the same magnetic pole, so that the rotating plate two 57 rotates and conflicts with the fixed vertical plate 34, and the driving motor two 22 starts to reverse, and the support rod 39 moves upward to the top of the placement slot (the upper part of the rotating plate one) at the other half of the placement slot three 53. Under the action of gravity and the spring 31, the lower horizontal plate 26 and the upper horizontal plate 25 are displaced, so that the rotating rod one 41 reaches the arc portion 48 of the push plate 46. Under the action of the spring 44, the rotating rod two 43 slides, pushing the push plate 46 to slide, so that the clamping hand head 47 slides, and the workpiece is no longer clamped, and the workpiece is put down for quenching; At the same time, the driving motor 22 on the other material-taking workpiece 6 is started, and the threaded rod 24 is driven to rotate through the corresponding pulley mechanism 23, thereby driving the upper horizontal plate 25 threadedly connected to the threaded rod 24 to move downward, thereby driving the lower horizontal plate 26 to move downward, so that the clamping head 47 moves downward, and the lower end surface of the clamping head 47 contacts the upper end surface of the object placement seat 2 18, and the upper horizontal plate 25 continues to move downward, so that the fixed column 37 moves downward, and the fixed plate 40 moves downward, so that the rotating rod 1 41 moves downward, and the rotating rod 1 41 enters the arc portion 48 of the push plate 46 To the vertical part 49, the push plate 46 slides, so that the clamping head 47 slides, and the multiple clamping heads 47 clamp and fix the workpiece. At the same time, the support rod 39 pushes the support plate 51 to move into the placement groove 2 50 through the oblique structure 54, and the support rod 39 slides to the bottom of the support plate 51. When the driving motor 22 rotates in the opposite direction, the support rod 39 supports the support plate 51. When the support rod 39 supports the support plate 51, the rotating rod 1 41 is in the vertical part 49 of the push plate 46. Therefore, at this time, the workpiece is still in a clamped and fixed state when the clamping rises, ensuring the stability of the clamping; After quenching is completed, the material-taking workpiece 6 at the upper end of the quenching workpiece clamps the workpiece, and the driving motor 20 is started, and the rotating support 5 is driven to rotate through the pulley mechanism 21, so that the two material-taking workpieces 6 on the rotating support 5 are exchanged, and the next round of workpiece placement quenching and workpiece clamping is carried out; Cylinder 12 extends out and pushes object placement seat 14 to the right side directly below the material-retrieving workpiece 6. In the above manner, the gripper head 47 descends to the designated position to grab the workpiece and then rises to the designated position; object placement seat 2 18 is also pushed to the left for a distance, and cylinder 2 16 extends out at the same time, pushing object placement seat 2 18 further to the material-retrieving station of another high-speed CVJ high-frequency quenching fully automatic production line. After retrieving the material, cylinder 12 and cylinder 2 16 retract to their original positions.

[0048] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
