[0002] Heat treatment is a crucial part of machining, and quenching is one method of heat treatment. Quenching fixtures typically only allow for single-workpiece quenching, resulting in low efficiency and failing to meet the demands of large-scale production. Furthermore, traditional quenching machine tools often employ manual loading and unloading, which is time-consuming, labor-intensive, and prone to safety hazards. This method cannot guarantee workpiece stability and quenching quality, easily leading to problems such as uneven quenching and insufficient hardness. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides a multi-station quenching fixture for shaft parts, including a housing. A partition plate is provided inside the housing, and a multi-station turntable mechanism is located above the partition plate. A quenching load driving mechanism is located on one side of the multi-station turntable mechanism, and a baffle is located on the outer side of the quenching load driving mechanism. The baffle is connected to the housing by a fixing member. A gap detection device is located on the other side of the multi-station turntable mechanism. The multi-station turntable mechanism includes a turntable, a transmission gear, a motor, movable wheels, a fixed frame, rollers, and a workpiece seat. A motor is mounted on one side of the housing via a support frame. The output shaft of the motor is fitted with a transmission gear, which meshes with a gear on the outer side of the turntable. A circular guide rail is provided on the lower surface of the turntable, and a fixed frame is located at the lower end of the turntable. The turntable is equipped with several rollers that cooperate with circular guide rails. Several workpiece seats are arranged along the circumference of the turntable. The quenching load driving mechanism includes a support column, guide rails, connecting blocks, sliders, a drive motor, and a quenching sensor. The support column is set on a spacer plate and has guide rails. The connecting block is hollow and fitted onto the guide rails. A slider is located inside the connecting block, and the outer contour of the slider corresponds to the inner contour of the guide rail. A quenching sensor is located outside the connecting block, and a motor is located on one side of the connecting block. The gap detection device includes a support frame, a telescopic rod, and a gap detection sensor. The support frame is set on the spacer plate, and the other end of the support frame is connected to the telescopic rod. The other end of the telescopic rod has a gap detection sensor. The gap detection sensor and the quenching sensor are located directly above the workpiece seats.
[0004] The front of the housing is provided with a sliding window.
[0005] The top of the housing is provided with a vent.
[0006] The turntable is divided into two equal parts, and workpiece seats are symmetrically arranged on each part.

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figure 1A multi-station quenching fixture for shaft parts includes a housing 1, a partition plate 2 inside the housing 1, a multi-station turntable mechanism 3 above the partition plate 2, a quenching load drive mechanism 4 on one side of the multi-station turntable mechanism 3, a baffle 6 on the outside of the quenching load drive mechanism 4, the baffle 6 being connected to the housing 1 by a fixing member 7, and a gap detection device 5 on the other side of the multi-station turntable mechanism 3. The multi-station turntable mechanism 3 includes a turntable 15, a transmission gear 16, a motor 17, movable wheels 18, a fixed frame 19, rollers 20, and a workpiece seat 21. The motor 17 is mounted on one side of the housing 1 via a support frame, and the output shaft of the motor 17 is fitted with a transmission gear 16, which meshes with a gear on the outside of the turntable 15. A circular guide rail is provided on the lower surface of the turntable 15, and a fixed frame 19 is provided at the lower end of the turntable 15. The fixed frame 19 is provided with several rollers 20, and the rollers 20 and the circular guide rail are connected to the workpiece seat 21. The turntable 15 is equipped with a series of workpiece seats 21 along its circumference. The quenching load drive mechanism 4 includes a support column 22, a guide rail 23, a connecting block 24, a slider 25, a drive motor, and a quenching sensor 26. The support column 22 is set on the spacer plate, and the guide rail 23 is provided on the support column 22. The connecting block 24 is hollow and fitted on the guide rail 23. The slider 25 is provided on the inner side of the connecting block 24. The outer contour of the slider 25 corresponds to the inner contour of the guide rail 23. The quenching sensor 26 is provided on the outer side of the connecting block 24. A motor is provided on one side of the connecting block 24. The empty space detection device 5 includes a support frame 8, a telescopic rod 9, and an empty space detection sensor 10. The support frame 8 is set on the spacer plate 2. The other end of the support frame 8 is connected to the telescopic rod 9. The other end of the telescopic rod 9 is provided with the empty space detection sensor 10. The empty space detection sensor 10 and the quenching sensor 26 are located directly above the workpiece seat 21.
[0017] The front of the housing 1 has a sliding window 11. A gripping robot arm is installed on the outside of the window. When the equipment is not in use, the window is closed by sliding.
[0018] The top of the housing 1 is provided with a vent 12, and the generated hot air is discharged through the vent 12 in conjunction with the fan.

[0022] In use, the loading and unloading robot loads the workpiece, grabs it, and places it on the workpiece seat 21. The motor 17 drives the turntable 15 to rotate 180°, and the workpiece rotates to a position below the quenching inductor. Then, the quenching load drive mechanism 4 drives the connecting block 24 to move up and down, causing the quenching inductor 26 to quench. The quenching inductor 26 generates an induced current on the workpiece surface, causing the workpiece surface to quickly reach the quenching temperature. Then, the workpiece is sprayed with water. Afterward, the turntable rotates 180° to reset. When the empty space detection device 5 detects that there is a workpiece on the workpiece seat 21, the loading and unloading robot performs the unloading operation. Then, when the empty space detection device 5 detects that there is no workpiece on the workpiece seat 21, the loading and unloading robot performs the loading operation. The loading and unloading operation of the loading and unloading robot is set to an interval of 2 minutes, and this cycle continues.
