The other end of the impact rod 46 is fitted with the outer surface of the placement frame 7, and a quenching pool 5 is fixedly installed on the inner wall of the bottom surface of the heat treatment box 1.

[0029] The specific implementation method is as follows: the electric telescopic column 6 moves the placement frame 7 into the quenching pool 5 to quench the spline sleeve. After the quenching is completed, the electric telescopic column 6 raises the placement frame 7. In the process of lowering and raising the placement frame 7, the placement frame 7 will drive the impact rod 46 to synchronously lower and rise through the positioning plate 43. Under the action of the fixed top block 42 on the fixed plate 41, the slider 48 causes the impact rod 46 to move backward first under the action of the fixed ring 45 and the telescopic spring 44. When the slider 48 is separated from the fixed top block 42, the impact rod 46 is restored to its original position under the action of the telescopic spring 44.

[0031] The specific implementation method is as follows: during the heat treatment of the spline sleeve, the driving motor 32 drives the reciprocating screw 33 to rotate. As the reciprocating screw 33 rotates, the threaded sleeve 34 is driven to move under the action of the thread. The threaded sleeve 34 drives the flip plate 36 to move back and forth in the placement frame 7 under the limit of the limit block through the telescopic rod 35. At this time, the flip plate 36 will flip the spline sleeve in the placement frame 7.

[0032] Working principle: after opening the box door 2, the spline sleeve is placed in the placement frame 7, and then the box door 2 is closed, and the heat treatment box 1 performs heat treatment on the spline sleeve in the placement frame 7. During the heat treatment of the spline sleeve, the driving motor 32 drives the reciprocating screw 33 to rotate. As the reciprocating screw 33 rotates, the threaded sleeve 34 is driven to move under the action of the thread. The threaded sleeve 34 drives the flip plate 36 to move back and forth in the placement frame 7 under the limit of the limit block through the telescopic rod 35. At this time, the flip plate 36 will flip the spline sleeve in the placement frame 7, and then the electric telescopic column 6 moves the placement frame 7 into the quenching pool 5 to quench the spline sleeve.

Under the action of the fixed top block 42 on the fixed plate 41, the slider 48 makes the impact rod 46 move backward first under the action of the fixed ring 45 and the telescopic spring 44. When the slider 48 is separated from the fixed top block 42, the impact rod 46 is restored to its original position under the action of the telescopic spring 44. At this time, the impact rod 46 hits the side wall of the placement frame 7, and the impacted placement frame 7 will vibrate, thereby shaking off the water adhering to the spline sleeve.
