[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1 to 7 In this embodiment of the invention, an auxiliary tooling for heat treatment of metal materials includes a barrel 1 and a lifting electromagnetic heating assembly 5. The lifting electromagnetic heating assembly 5 performs high-frequency electromagnetic heating on the metal workpiece upon startup, followed by cooling the heated metal workpiece using a spray cooling device. Coolant, after cooling the workpiece, enters the barrel 1. Return holes for coolant outflow are provided around the perimeter of the barrel 1. A rotating disk 2 is rotatably connected inside the barrel 1. Connecting columns 3 are equidistantly fixed to the top of the rotating disk 2. When the rotating disk 2 rotates, it drives the connecting columns 3 to rotate. The top of the connecting columns 3 passes through… The connecting mechanism is detachably connected to a connector 4. The connector 4 rotates with the rotating connecting column 3. Each connector 4 is a workstation. Multiple workstations drive the workpiece to move directly below the lifting electromagnetic heating assembly 5. The outer wall of the connector 4 is integrally formed with a tray 14. The tray 14 is used to support the bottom end of the metal workpiece. The diameter of the tray 14 should be smaller than the diameter of the workpiece. The diameter of the connector 4 should be equal to the internal diameter of the workpiece. The workpiece here is a gear. The bottom end of the barrel 1 is equipped with a drive motor 8 and two electric push cylinders 7. The drive motor 8 is located between the two electric push cylinders 7.

[0033] The connecting mechanism is used to simultaneously fix multiple connectors 4 to the top of multiple connecting posts 3;

[0034] The output end of the electric push cylinder 7 is connected to a lifting mechanism. The lifting mechanism in the rising state is used to simultaneously release the multiple connecting mechanisms from the multiple connecting heads 4.

[0035] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The connecting mechanism includes: a mating hole 12, a plug post 15, a locking hole 16, a connecting groove 17, a connecting plate 18, an upper fixing plate 19, a first pressure-bearing surface 20, a spring 21, a lower fixing plate 22 and a lower pressure-bearing surface 23;

[0036] Multiple circumferentially distributed mating holes 12 are opened at the bottom of the rotating disk 2 and extend into the inner cavity of the connecting post 3. The insertion post 15 is integrally formed at the bottom of the connector 4 and inserted into the top of the inner cavity of the mating hole 12. The insertion post 15 moves downward from above the connector 4 and inserts into the top of the inner cavity of the mating hole 12 to achieve the mating of the connector 4 and the connecting post 3. The locking hole 16 is opened horizontally inside the insertion post 15. After the insertion post 15 is fully inserted into the mating hole 12, the openings at both ends of the locking hole 16 are aligned with the opening at the top of the connecting groove 17.

[0037] The connecting groove 17 is opened inside the connecting post 3. The vertical cross section of the connecting groove 17 is in the shape of a "C". The connecting plate 18 is horizontally slidably connected to the inside of the connecting groove 17. The upper fixing plate 19 and the lower fixing plate 22 are integrally formed at the upper and lower ends of the connecting plate 18, and respectively pass through the openings at both ends of the connecting groove 17 to the inner cavity of the docking hole 12. When the plug post 15 is inserted into the docking hole 12, the plug post 15 will contact the upper fixing plate 19 and squeeze the upper fixing plate 19. The upper fixing plate 19 is forced to move the connecting plate 18. The connecting plate 18 slides in the connecting groove 17 and drives the lower fixing plate 22 to move synchronously until the slots at both ends of the locking hole 16 are aligned with the opening at the top of the connecting groove 17. Then the upper fixing plate 19 is reset and locked into the locking hole 16 to complete the locking of the connector 4.

[0038] A spring 21 is installed on the lower inner wall of the connecting groove 17. One end of the spring 21 is connected to the connecting plate 18. When the upper fixed plate 19 and the lower fixed plate 22 are moved by force, the connecting plate 18 is moved and the connecting plate 18 presses the spring 21. The spring 21 is compressed after being pressed. When the pressing force is small, the compressed spring 21 returns to its original state and drives the upper fixed plate 19 and the lower fixed plate 22 to return to their original state through the connecting plate 18.

[0039] The first pressure-bearing surface 20 is formed on the end of the upper fixed plate 19 away from the connecting plate 18. When the plug-in post 15 contacts the upper fixed plate 19, the first pressure-bearing surface 20 contacts the plug-in post 15. The downward pressure of the plug-in post 15 drives the upper fixed plate 19 to move through the first pressure-bearing surface 20. The lower pressure-bearing surface 23 is formed on the end of the lower fixed plate 22 away from the connecting plate 18. The lower pressure-bearing surface 23 is used to receive the extrusion force of the lifting mechanism, thereby realizing the movement of the lower fixed plate 22 under force.

[0040] Please refer to this carefully. Figure 2 and Figure 3 The lifting mechanism includes: a movable plate 6, a sliding groove 10, ball bearings 11, and a docking shaft 13;

[0041] The movable disc 6 is movably connected to the inner cavity of the barrel 1, and the ball bearing 11 is movably connected to the output end of the electric push cylinder 7. When the electric push cylinder 7 is running, it drives the movable disc 6 to move upward. The sliding groove 10 is opened in a ring at the bottom of the movable disc 6 and contacts the surface of the ball bearing 11. When the movable disc 6 rotates with the synchronous shaft 9, the sliding groove 10 and the surface of the ball bearing 11 roll, thereby reducing the friction force on the movable disc 6 when it rotates. Multiple docking shafts 13 are circumferentially distributed at the top of the movable disc 6, and the multiple docking shafts 13 correspond one-to-one with the multiple docking holes 12 in the vertical direction. When the docking shafts 13 move upward with the movable disc 6, they are inserted into the inner cavity of the docking holes 12. At this time, the docking shafts 13 apply a squeezing force to the lower pressure surface 23 on the lower fixed plate 22, thereby achieving the effect of the lower fixed plate 22 moving under force.

[0042] Please refer to this carefully. Figure 2 and Figure 3 The output end of the drive motor 8 is connected to the synchronous shaft 9. The drive motor 8 and the synchronous shaft 9 are connected by a coupling. When the drive motor 8 runs, it will drive the synchronous shaft 9 to run synchronously. The cross-section of the synchronous shaft 9 has a "convex" shape. The output end of the synchronous shaft 9 is fixedly connected to the bottom end of the rotating disk 2. The movable disk 6 has a sliding groove that matches the outer wall of the synchronous shaft 9 at the contact position with the synchronous shaft 9. When the synchronous shaft 9 rotates, it drives the movable disk 6 and the rotating disk 2 to rotate synchronously. The cross-section of the sliding groove has a "convex" shape. The movable disk 6 and the synchronous shaft 9 are connected to slide up and down through the sliding groove. When the electric push cylinder 7 runs, the electric push cylinder 7 pushes the movable disk 6 to move up and down along the outer wall of the synchronous shaft 9.

[0043] Please refer to this carefully. Figure 7 The lifting electromagnetic heating assembly 5 includes: a bracket 501, a lifting motor 502, a slide bar 503, a threaded column 504, a fixed base 505, and a high-frequency electromagnetic heater 506;

[0044] The bracket 501 is fixedly connected to the outer wall of the barrel 1. The bracket 501 supports the fixed seat 505 and the high-frequency electromagnetic heater 506. The lifting motor 502 is installed at the bottom of the bracket 501, and the output end of the lifting motor 502 extends through to the top of the bracket 501 and is rotatably connected to the bracket 501. When the lifting motor 502 is running, the bearing at the connection between the lifting motor 502 and the bracket 501 can effectively reduce friction.

[0045] The threaded column 504 is connected to the output end of the lifting motor 502. The threaded column 504 is connected to the lifting motor 502 through a coupling. The operation of the lifting motor 502 drives the threaded column 504 to rotate. The fixed seat 505 is threadedly connected to the threaded column 504. When the threaded column 504 rotates, the fixed seat 505 moves up and down along the outer wall of the threaded column 504. The slide rod 503 is fixedly connected to the top of the bracket 501 and slidably connected to the fixed seat 505. The slide rod 503 restricts the fixed seat 505 so that the fixed seat 505 can only move up and down. The high-frequency electromagnetic heater 506 is installed on the fixed seat 505. When the heating part of the high-frequency electromagnetic heater 506 moves to the outside of the workpiece, the workpiece can be heated.

[0046] Please refer to this carefully. Figure 3 and Figure 4 The cross-sections of the plug-in post 15, the docking hole 12, and the docking shaft 13 are all elliptical, and the inner wall of the docking hole 12 matches the outer wall of the plug-in post 15 and the docking shaft 13. The elliptical structure can effectively ensure the accuracy of the position of the plug-in post 15 and the docking shaft 13 when they are inserted into the docking hole 12, and will not cause the problem of misalignment between the lock hole 16 and the upper fixing plate 19 due to the plug-in post 15 being inserted at different angles.

[0047] Please refer to this carefully. Figure 5 Two connecting grooves 17 are provided inside a connecting post 3, and the two connecting grooves 17 are symmetrically arranged about the central axis of the connecting post 3. The top openings of the two connecting grooves 17 are aligned with the openings at both ends of the lock hole 16, and the lock hole 16 can effectively realize the locking function.
