DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] As attached Figure 1 -Attached Figure 3 As shown, a vertical vacuum oil quenching furnace material quenching lifting mechanism includes a reduction motor 1, a steering gearbox 3, and a material tray 17. The reduction motor 1 is fixedly mounted via a motor base 2. A set of lifting assemblies is provided on each side of the material tray 17, and the two sets of lifting assemblies can drive the material tray 17 up and down. The reduction motor 1 drives the two sets of lifting assemblies through two steering gearboxes 3, which are fixedly mounted via a fixed base 4. The reduction motor 1 is connected to the input end of the steering gearbox 3 via a coupling 5. The motor base 2 and the fixed base 4 are welded to the outer shell of the vertical vacuum furnace.

[0019] The lifting assembly includes a drive shaft 6 and a rotating shaft 10, which are arranged vertically. The output end of the steering gearbox 3 is connected to the drive shaft 6 through a fixed seat 4. A bearing 7 is mounted on a mounting seat 8. The end of the drive shaft 6 away from the steering gearbox 3 is rotatably mounted in the bearing 7. At least two bearings 12 are provided. The rotating shaft 10 is rotatably mounted in the bearings 12. The bearings 12 are fixedly mounted via a mounting seat 13. Two driving sprockets 9 are mounted on the drive shaft 6, and two driven sprockets 11 are mounted on the rotating shaft 10. The driving sprockets 9 and the driven sprockets 11 are arranged vertically opposite each other. A chain 14 is connected between the corresponding driving sprockets 9 and the driven sprockets 11. Four support ears 18 are provided on the outer periphery of the material tray 17, two on each side and arranged symmetrically. The chain 14 is connected to the support ears 18. The mounting seat 18 and the mounting seat 2 13 are welded to the interior of the vertical vacuum furnace for fixation.

[0020] The reduction motor 1 drives the input of the steering gearbox 3 through the coupling 5. The input of the steering gearbox 3 then drives the drive shaft 6 through the coupling 5, causing the drive shaft 6 to rotate. The drive shaft 6 drives the driving sprocket 9, which in turn drives the chain 14, thereby moving the material tray 17. The reduction motor 1 drives the two lifting assemblies, so that the chains 14 run synchronously, ensuring the smooth lifting of the material tray 17 and preventing it from deflecting during the lifting process.

[0021] The supporting ear 18 is provided with a connecting block 19 , and the chain 14 is connected to the supporting ear 18 via the connecting block 19 . The provision of the connecting block 19 makes the connection between the chain 14 and the supporting ear 18 more convenient and more secure.

[0022] A mounting block 15 is welded inside the vacuum furnace, and a guide rail 16 is installed inside the mounting block 15. The guide rail 16 is vertically arranged and located in the middle of the two chains 14. A mounting plate 20 is installed on the outside of the material tray 17, and a roller seat 21 is connected to the outside of the mounting plate 20. A roller 22 is rotatably arranged on the outside of the roller seat 21. The axial direction of the roller 22 is perpendicular to the end face of the roller seat 21, and the roller 22 can be located inside the guide rail 16. During the lifting and lowering process of the material tray 17, the roller 22 can move and rotate along the guide rail 16, thereby playing a guiding role, allowing the material tray 17 to be lifted and lowered smoothly. The reduction motor 1 is equipped with an encoder. After the lifting stroke is in place, the encoder gives a signal, the reduction motor 1 is braked, and the material tray 17 stops moving.

[0023] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
