Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, specifically to a heating furnace for bearing ring processing. Background Technology

[0002] In the process of bearing ring processing, the bearing rings are usually heated in a heating furnace. Currently, there are various bearing ring heating devices in the industry. Among them, publication number "CN218989341U" discloses a medium-frequency induction heating furnace for bearing ring forging production, belonging to the field of bearing ring processing technology. It includes a heating furnace, and the back of the heating furnace is equipped with an adjustment component. The adjustment component is hinged to a rotating component via a pin. This medium-frequency induction heating furnace for bearing ring forging production is equipped with a turntable, lead screw, movable block, sliding hole, rotating rod and clamping plate, and a reverse screw. When the screw moves out of the movable plate, the rotating tube rotates around the pin, thereby driving several bearing ring forgings to move to the vertical direction. The control cylinder retracts, and the retracting cylinder drives several bearing ring forgings to move neatly into the heating furnace. The control cylinder extends, and the extended cylinder can drive several bearing ring forgings out of the heating furnace through the movable plate and rotating component. The operation is simple, allowing users to easily pick up and put away multiple bearing ring forgings that need to be heated.

[0003] However, the above technology still has some shortcomings. When heating the bearing rings, the unheated bearing rings cannot be placed. They must be removed after the bearing rings in the heating furnace are heated, which reduces the overall work efficiency and affects production efficiency. At the same time, the bearing rings placed in the heating furnace are in a static state. This may cause some areas to be too hot or too cold during heating, resulting in uneven heating of the bearing rings. Utility Model Content

[0004] To address the problem of uneven heating of bearing rings caused by the inability to place unheated bearing rings while heating bearing rings, and the fact that bearing rings in the heating furnace are in a stationary state, the purpose of this utility model is to provide a heating furnace for processing bearing rings.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a heating furnace for processing bearing rings, comprising a heating furnace, a support plate fixedly installed on one side of the heating furnace, a first electric telescopic rod fixedly installed at the top edge of the support plate, a vertical plate fixedly installed at the drive end of the first electric telescopic rod, a rack fixedly installed on the side of the vertical plate near the heating furnace, a first gear meshing with the side of the rack away from the vertical plate, a first rotating shaft fixedly installed in the middle of the first gear, the first rotating shaft being rotatably engaged with the support plate, a turntable fixedly installed at the top of the first rotating shaft, a second electric telescopic rod fixedly installed at the top of the turntable, a top plate fixedly installed at the drive end of the second electric telescopic rod, a dual-axis motor fixedly installed at the top of the top plate, and two drive ends of the dual-axis motor... Each of the two shafts is fixedly installed with a second rotating shaft. Each shaft has a rotating mechanism at its end furthest from the top plate. The rotating mechanism includes a connecting block, which is fixedly connected to the second rotating shaft. A U-shaped block is located at the bottom of the connecting block, and a horizontal plate is fixedly installed at the bottom of the U-shaped block. Two symmetrically distributed fixing blocks are fixedly installed at the top of the horizontal plate. A double-ended screw with opposite threads is rotatably threaded through the top of each fixing block. Two symmetrically distributed T-shaped plates are threaded to the outer sides of the double-ended screws. A connecting plate is fixedly installed at the bottom of each T-shaped plate, and a half-sleeve is fixedly installed on the outer side of the connecting plate. A limiting groove for cooperation with the T-shaped plate is opened through the top of the horizontal plate. A rotating wheel is fixedly installed at one end of each double-ended screw. The two rotating mechanisms have identical structures and are in opposite directions.

[0006] Preferably, each of the rotating structures further includes two fixed plates, which are fixedly connected to the corresponding connecting blocks. A third rotating shaft is rotatably passed through the middle of the fixed plate. A half-face gear is fixedly installed at the end of the third rotating shaft near the U-shaped block. A fourth rotating shaft is fixedly installed at the end of the U-shaped block near the connecting block.

[0016] 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.

[0017] Example: Figure 1-4As shown, this utility model provides a heating furnace for processing bearing rings, including a heating furnace 1. A support plate 11 is fixedly installed on one side of the heating furnace 1. A first electric telescopic rod 12 is fixedly installed at the top edge of the support plate 11. A vertical plate 13 is fixedly installed at the driving end of the first electric telescopic rod 12. A rack 14 is fixedly installed on the side of the vertical plate 13 near the heating furnace 1. A first gear 15 is meshed with the side of the rack 14 away from the vertical plate 13. A first rotating shaft 16 is fixedly installed in the middle of the first gear 15. The first rotating shaft 16 is rotatably engaged with the support plate 11. A turntable 17 is fixedly installed at the top of the first rotating shaft 16. A second electric telescopic rod 18 is fixedly installed at the top of the turntable 17. A top plate 19 is fixedly installed at the driving end of the second electric telescopic rod 18. A dual-axis motor 2 is fixedly installed at the top of the top plate 19. A second rotating shaft 21 is fixedly installed on both driving ends of the dual-axis motor 2. A rotating mechanism is provided at the end of each of the two second rotating shafts 21 away from the top plate 19.

[0018] The rotating mechanism includes a connecting block 22, which is fixedly connected to the second rotating shaft 21. The bottom end of the connecting block 22 is provided with a U-shaped block 23. A horizontal plate 24 is fixedly installed at the bottom end of the U-shaped block 23. Two symmetrically distributed fixing blocks 25 are fixedly installed at the top end of the horizontal plate 24. A double-ended screw 26 with opposite threads is rotatably passed through the top of the fixing block 25. Two symmetrically distributed T-shaped plates 27 are threaded to the outer side of the double-ended screw 26. A connecting plate 28 is fixedly installed at the bottom end of the T-shaped plate 27. A half sleeve 29 is fixedly installed on the outer side of the connecting plate 28. A limiting groove for cooperating with the T-shaped plate 27 is opened through the top end of the horizontal plate 24. A rotating wheel 20 is fixedly installed at one end of the double-ended screw 26. The two rotating mechanisms have the same structure and are in opposite directions.

[0019] Each rotating structure also includes two fixed plates 3, which are fixedly connected to the corresponding connecting blocks 22. A third rotating shaft 31 is rotatably passed through the middle of the fixed plate 3. A half-face gear 32 is fixedly installed at the end of the third rotating shaft 31 near the U-shaped block 23. A fourth rotating shaft 33 is fixedly installed at the end of the U-shaped block 23 near the connecting block 22. A second gear 34 that works with the half-face gear 32 is fixedly installed on the outside of the fourth rotating shaft 33. The fourth rotating shaft 33 is rotatably locked on the connecting block 22. A drive motor 35 is fixedly installed at the end of one of the fixed plates 3 away from the half-face gear 32. The drive end of the drive motor 35 is fixedly connected to the third rotating shaft 31.

[0020] The vertical plate 13 is fitted with a sliding seat 4 on its outer side. The sliding seat 4 is fixed on the support plate 11. By setting the sliding seat 4, the vertical plate 13 is guided, so that the rack 14 can move back and forth normally.

[0021] Two sets of telescopic legs 5 are symmetrically distributed and fixedly installed at the top of the turntable 17. The telescopic legs 5 are fixedly connected to the top plate 19. By setting the telescopic legs 5, the top plate 19 is more stable when moving up and down.

[0022] Two symmetrically distributed buffer pads 6 are fixedly installed at the end of each horizontal plate 24 away from the fixed block 25. The buffer pads 6 are located at the edge of the horizontal plate 24. By setting the buffer pads 6, the horizontal plate 24 moving downward is buffered between itself and the heating furnace 1, so as to avoid damage to the heating furnace 1 due to the downward gravity when the horizontal plate 24 is in contact with the heating furnace 1, which would affect the normal use of the heating furnace 1.

[0023] A controller 7 is fixedly installed at the edge of the upper surface of the support plate 11. The first electric telescopic rod 12, the second electric telescopic rod 18, the dual-axis motor 2, and the drive motor 35 are all electrically connected to the controller 7. By setting the controller 7, it is convenient to control the start and stop of the first electric telescopic rod 12, the second electric telescopic rod 18, the dual-axis motor 2, and the drive motor 35.

[0024] Each second rotating shaft 21 is rotatably fitted with a fixed seat 8, which is fixedly connected to the top plate 19. By setting the fixed seat 8, the second rotating shaft 21 is further supported, making the second rotating shaft 21 more stable when rotating.

[0025] The two rotating wheels 20 are positioned opposite each other, making it easier to rotate the rotating wheels 20 and drive the double-headed screw 26 to rotate.

[0026] Working principle: In actual use, multiple bearing rings are first placed on the outside of the two right-side half-sleeves 29. Then, the rotating wheel 20 is rotated, which drives the double-headed screw 26 to rotate. The double-headed screw 26 drives the T-shaped plate 27 to move to both sides in the sliding groove. The movement of the T-shaped plate 27 drives the connecting plate 28 and the half-sleeves 29 to move to both sides, so that the half-sleeves 29 contact the inner side of the bearing rings, thereby clamping and fixing the bearing rings. When the bearing rings are placed, the left half-sleeve 29 is moved away from the heating furnace 1. After the bearing rings on the right half-sleeve 29 are fixedly installed, the first electric telescopic rod 12 is started, which drives the vertical plate 13 and the rack 14 to move. The meshing between the rack 14 and the first gear 15 drives the first rotating shaft 16 to rotate in the support plate 11, and drives the turntable 17, the second electric telescopic rod 18, the top plate 19, the dual-shaft motor 2, the second rotating shaft 21, and the rotating mechanism to rotate 180 degrees.

[0027] Subsequently, the half-sleeve 29 containing the bearing rings is positioned above the heating furnace 1, but the half-sleeve 29 containing the bearing rings is still positioned above. The dual-shaft motor 2 is started, driving the second rotating shaft 21 and the rotating mechanism to rotate 180 degrees, so that the half-sleeve 29 containing the bearing rings is positioned below. The second electric telescopic rod 18 is then started, driving the top plate 19 and the rotating mechanism to move downwards and enter the heating furnace 1. Then, the drive motor 35 on the rotating mechanism placed in the heating furnace 1 is started, driving the third rotating shaft 31 and the half-face gear 32 to rotate. When the half-face gear 32 meshes with the second gear 34, it drives the fourth rotating shaft 33, the U-shaped block 23 and the mechanism below the U-shaped block 23, causing the bearing rings to rotate. When the half-face gear 32 does not mesh with the second gear 34, the bearing rings stop rotating, thereby realizing the intermittent rotation of the bearing rings in the heating furnace 1, making the bearing rings heat more evenly.

[0028] While heating the bearing rings in the heating furnace 1, the bearing rings are placed on the other half-sleeve 29, which holds each bearing ring. After the bearing rings in the heating furnace 1 are heated, the second electric telescopic rod 18 is activated to move the bearing rings upward and detach them from the heating furnace 1. The operation can then be repeated. However, before activating the dual-shaft motor 2, the wheel 20 on the heated bearing ring is rotated in the opposite direction so that the half-sleeve 29 does not clamp the bearing rings, and they fall directly to the next process. The operation can then be repeated.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
