Several support plates 5 are vertically fixedly connected to the inner bottom of the vacuum heat treatment furnace 2, and the support plates 5 are arranged equidistantly. The furnace is characterized in that rails 6 are fixedly connected to the front and rear sides of the top of the workbench 1. The top of the rails 6 has movable plates 7. Wheels 8 are rotatably connected to the bottom of the left and right ends of the movable plates 7, and the wheels 8 slide and engage with the rails 6. Connecting plates 9 are fixedly connected to the opposite side walls of the two movable plates 7. A tray 10 is fixedly connected between the opposite ends of the two connecting plates 9. A bearing 32 is embedded inside the upper end of the tray 10, and the inner ring of the bearing 32 is fitted onto the tray 10. A turntable 1 is rotatably connected to the tray 10 through the bearing 32. 1. A servo motor 12 is fixedly installed at the bottom of the tray 10. The top of the output shaft of the servo motor 12 is fixedly connected to the center of the bottom of the turntable 11. A support frame 13 is vertically fixedly connected to the top left of the turntable 11. A horizontal plate 33 is vertically connected to the top of the support frame 13. Two guide rods 14 are fixedly connected between the horizontal plate 33 and the top of the turntable 11. The two guide rods 14 are parallel and pass through both ends of the lifting seat 15. The two guide rods 14 are slidably connected to the lifting seat 15. A lifting support plate 16 is fixedly connected to the bottom of the right side wall of the lifting seat 15. The lifting support plate 16 is clearance-fitted with the support plate 5. A lifting drive mechanism is fixedly installed at the top of the horizontal plate 33. The lifting drive mechanism is fixedly connected to the middle of the left end of the lifting support plate 16. A moving drive mechanism is fixedly installed at the bottom of the worktable 1. A connecting seat 31 is fixedly connected to the bottom of the outer wall of the moving plate 7. The connecting seat 31 is connected to the moving drive mechanism.
[0020] The lifting drive mechanism includes two fixed seats 17, which are vertically fixedly connected to the front and rear sides of the top of the horizontal plate 33, respectively. A rotating shaft 18 is rotatably connected between the tops of the two fixed seats 17. The rotating shaft 18 passes vertically through the rope reel 19 and is fixedly connected to the rope reel 19. A rope 20 is wound around the outer wall of the rope reel 19. One end of the rope 20 is fixedly connected to the outer wall of the rope reel 19, and the other end of the rope 20 extends downward and is fixedly connected to the center of the top left side of the lifting support plate 16. A servo reduction motor 21 is fixedly installed on the top of the horizontal plate 33. The output shaft end of the servo reduction motor 21 and the outer wall of the rotating shaft 18 are both fixedly connected to pulleys 22. The output shaft of the servo reduction motor 21 is vertically fixedly connected to the center of the pulleys 22. The pulleys 22 are fixedly sleeved on the outer wall of the rotating shaft 18, and a belt 23 is sleeved between the outer walls of the two pulleys 22.
[0021] The moving drive mechanism includes auxiliary legs 24. Two auxiliary legs 24 are fixedly connected to the bottom front and rear sides of the worktable 1, respectively. The auxiliary legs 24 are located below the right end of the track 6. A lead screw 25 is rotatably connected between the left side wall of the auxiliary legs 24 and the bottom side wall of the worktable 1. The left ends of the two lead screws 25 pass through the bottom of the worktable 1. A bevel gear 26 is fixedly connected to the left end of each lead screw 25. A fixed tube 27 is fixedly connected to the left outer wall of the worktable 1. The fixed tube 27 is located between the two bevel gears 26. A rotating shaft 28 is rotatably connected inside the fixed tube 27. A bevel gear 29 is fixedly connected to both the front and rear ends of the rotating shaft 28. The two bevel gears 29 mesh with the two bevel gears 26, respectively. A lead screw motor 30 is fixedly installed on the right side wall of the rear auxiliary legs 24. The output shaft of the lead screw motor 30 is fixedly connected to the right end of the rear lead screw 25. The lead screw 25 passes through the bottom of the connecting seat 31. The bottom of the connecting seat 31 is threadedly connected to the lead screw 25.
[0022] The lifting pallet 16 is fork-shaped, and the support plate 5 is composed of several parallel upright plates. The structural features of the lifting pallet 16 and the support plate 5 are consistent with the structural features of the components in the reference patent mentioned in the background art.
[0023] When materials need to be added, open the furnace door 3, place the materials on the lifting tray 16, start the servo motor 12, and the output shaft of the servo motor 12 drives the turntable 11 to rotate.
[0024] When the turntable 11 rotates, the support frame 13, guide rod 14, lifting seat 15 and lifting pallet 16 on it also rotate, so that the lifting pallet 16 faces the vacuum heat treatment furnace 2.
[0025] When the moving drive mechanism is started, the lead screw motor 30 drives the lead screw 25 to rotate. Since the connecting seat 31 is threadedly connected to the lead screw 25, the moving plate 7 will move left and right along the track 6, thereby moving the tray 10 to the left side or outside of the vacuum heat treatment furnace 2. The lifting tray 16 moves into the vacuum heat treatment furnace 2 and is located above the support plate 5. When the lifting tray 16 arrives, the moving drive mechanism is stopped.
[0026] When the lifting drive mechanism is started, the servo reduction motor 21 drives the rotating shaft 18 to rotate, which in turn drives the rope disc 19 to rotate. When the rope disc 19 rotates, the rope 20 wrapped around it gradually unfolds or tightens, thereby driving the lifting pallet 16 to move up and down.
[0027] The movement of the lifting pallet 16 is guided by the guide rod 14, ensuring the stability and accuracy of the lifting process.
[0028] First, the lifting pallet 16 is driven to move downwards. The lifting pallet 16 is in clearance fit with the support plate 5. The downward movement of the lifting pallet 16 causes the material to fall onto the support plate 5. Then, the moving drive mechanism is activated to drive the lifting pallet 16 to move to the left, away from the vacuum heat treatment furnace 2. The furnace door 3 is closed, and the electric heating element 4 is activated for heat treatment, completing the material loading. This structure allows long strip-shaped materials to be easily rotated and adjusted in position, facilitating the loading and unloading of materials.
[0029] When you need to remove the material, simply follow the steps above in reverse order to remove it.
[0030] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
