Description

Technical Field

[0001] This utility model belongs to the field of slewing bearing processing technology, specifically relating to an environmentally friendly precision controllable quenching equipment for slewing bearings. Background Technology

[0002] The environmentally friendly precision controllable quenching equipment for slewing bearings is a specialized piece of equipment for heat treatment of slewing bearings, designed to achieve a highly efficient, precise, and environmentally friendly quenching process. This equipment possesses high precision and controllability, enabling precise control of various parameters during the quenching process, such as temperature, time, and cooling rate, thereby ensuring the quality of the slewing bearing's heat treatment. Environmental factors were fully considered in the design, employing advanced energy-saving technologies and environmentally friendly materials to reduce energy consumption and waste emissions, meeting the requirements of modern industrial green production. The quenching process is highly efficient and stable, significantly improving production efficiency while ensuring product quality and consistency.

[0003] The working principle of environmentally friendly precision controllable quenching equipment for slewing bearings typically involves two key steps: induction heating and precise cooling. Through induction heating technology, the equipment can rapidly heat the surface of the slewing bearing to the quenching temperature, and then achieve rapid and uniform cooling through a precise cooling system, thereby obtaining the desired hardened layer and microstructure.

[0004] Existing quenching equipment commonly employs water spray pipes to rinse and cool the surface of slewing bearings during the cooling process. However, this traditional rinsing cooling method reveals significant limitations in practical applications, primarily in its incomplete cooling. Specifically, due to limitations in the design layout of the water spray pipes, the spray angle, and the water flow intensity, it is often difficult to ensure that every part of the slewing bearing surface receives uniform and sufficient rinsing. Furthermore, the water spray rinsing method can be further affected by uneven water flow distribution and differences in water flow impact force, exacerbating the unevenness of the cooling process and ultimately adversely affecting the overall performance and quality of the slewing bearing. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly precision controllable quenching equipment for slewing bearings. It aims to solve the problem that existing flushing and cooling methods are often limited by factors such as the design layout of the water spray pipe, the spray angle, and the water flow intensity, making it difficult to ensure that every part of the slewing bearing surface is uniformly and fully flushed. Furthermore, the water spray pipe flushing method may be affected by factors such as uneven water flow distribution and differences in water flow impact force, which further exacerbates the unevenness of the cooling process and ultimately has an adverse effect on the overall performance and quality of the slewing bearing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly precision controllable quenching equipment for slewing bearings, comprising an equipment base, a quenching body, a support, a quenching heating ring, and a cooling pool. The quenching body is mounted on the surface of the equipment base, the support is connected to the side surface of the quenching body, the quenching heating ring is connected to the bottom side of the support, and a cooling pool is connected to one side of the equipment base directly below the quenching heating ring. Three sets of first sealed bearings are fitted inside the cooling pool in a circular array with their center lines as the center. Threaded rods are respectively connected through the interior of the three sets of first sealed bearings, and matching threaded sleeves are fitted onto the surfaces of the three sets of threaded rods. The threaded sleeves are connected to the outer surface of the movable seat, and a fixing component is connected to the top of the movable seat.

[0007] As a preferred embodiment of the environmentally friendly slewing bearing precision controllable quenching equipment of this utility model, the fixing component includes a rotating rod, a support plate, a push rod, and an inner liner block. The top of the rotating rod is connected to the support plate, and three sets of push rods are installed in a circular array around the center line of the support plate on the upper surface of the support plate.

[0008] As a preferred embodiment of the environmentally friendly slewing bearing precision controllable quenching equipment of this utility model, the movable ends of the three sets of push rods are respectively connected to an inner liner block, so that the push rod drives the inner liner block to move axially, and the outer surface of the inner liner block is set as arc.

[0009] As a preferred embodiment of the environmentally friendly slewing bearing precision controllable quenching equipment of this utility model, each of the three sets of inner lining blocks is symmetrically connected to a sliding sleeve on both sides, and the sliding sleeve is fitted onto the slide rail connected to the surface of the support plate.

[0010] As a preferred embodiment of the environmentally friendly slewing bearing precision controllable quenching equipment of this utility model, the end of the rotating rod is fitted with a second sealed bearing that is fitted and installed on the upper surface of the movable seat, and the surface of the rotating rod is connected to a driven gear plate.

[0011] As a preferred embodiment of the environmentally friendly slewing bearing precision controllable quenching equipment of this utility model, a first drive motor is installed inside the movable seat, and the output end of the first drive motor is connected to a drive gear that meshes with the driven gear.

[0012] As a preferred embodiment of the environmentally friendly slewing bearing precision controllable quenching equipment of this utility model, the ends of the three sets of threaded rods are respectively connected to a pulley, the surfaces of the three pulleys are fitted with belt rings, and the ends of the threaded rods are connected to the output end of the second drive motor installed on the inner wall of the cooling tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the second drive motor drives the threaded rod connected to it to rotate in the opposite direction, and through the pulley and belt ring, drives the other two threaded rods to rotate in the opposite direction. When the threaded rods rotate in the opposite direction, they can drive the threaded sleeve to move downward. The downward movement of the threaded sleeve drives the slewing bearing to move downward through the movable seat and the support plate. When the slewing bearing moves downward into the water of the cooling pool, the slewing bearing can be cooled by the water. This allows for all-round cooling of the slewing bearing and avoids uneven cooling that could affect the quality of the slewing bearing.

[0015] In this invention, the push rod can compress the inner liner block to move laterally during operation. When the inner liner block moves laterally to the inner wall of the slewing bearing, the position of the slewing bearing can be fixed. When the first drive motor runs, it drives the active gear disk to rotate. When the active gear disk rotates, it can drive the support plate to rotate through the driven gear disk. When the support plate rotates, it can drive the slewing bearing fixed on its surface to rotate, thus achieving uniform heating and quenching of the slewing bearing. Attached Figure Description

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.

[0024] Please see Figures 1-5 This utility model provides the following technical solution: an environmentally friendly slewing bearing precision controllable quenching equipment, including an equipment base 1, a quenching body 2, a support 3, a quenching heating ring 4, and a cooling pool 5. The quenching body 2 is installed on the surface of the equipment base 1, the support 3 is connected to the side surface of the quenching body 2, the quenching heating ring 4 is connected to the bottom side of the support 3, and the cooling pool 5 is connected to one side of the equipment base 1 located directly below the quenching heating ring 4. Three sets of first sealed bearings 6 are fitted inside the cooling pool 5 in a circular array with their center lines as the center. Threaded rods 7 are respectively connected through the interior of the three sets of first sealed bearings 6. Threaded sleeves 8 are respectively fitted onto the surface of the three sets of threaded rods 7. Threaded sleeves 8 are connected to the outer surface of the movable seat 9, and a fixing component is connected to the top of the movable seat 9.

[0025] The slewing bearing is first fixed using a precision controllable quenching equipment. Then, the quenching heating ring 4 is adjusted to fit onto the surface of the slewing bearing. Finally, the quenching body 2 controls the heating of the quenching heating ring 4 to quench the slewing bearing.

[0026] Preferably, the fixing assembly includes a rotating rod 11, a support plate 12, push rods 13 and an inner liner block 14. The top of the rotating rod 11 is connected to the support plate 12, and three sets of push rods 13 are installed in a circular array around the center line of the support plate 12 on the upper surface of the support plate 12.

[0027] Preferably, the movable ends of the three sets of push rods 13 are respectively connected to an inner liner block 14, so that the push rods 13 drive the inner liner block 14 to move axially, and the outer surface of the inner liner block 14 is set to be arc-shaped.

[0028] In practical use, when the slewing bearing is placed on the surface of the support plate 12 and sleeved on the outside of the inner liner block 14, the extension of the push rod 13 can drive the inner liner block 14 to move laterally. When the inner liner block 14 moves laterally to the inner wall of the slewing bearing, the position of the slewing bearing can be fixed.

[0029] Preferably, each of the three sets of inner lining blocks 14 is symmetrically connected to a sliding sleeve 15 on both sides, and the sliding sleeve 15 is fitted onto the slide rail 16 connected to the surface of the support plate 12.

[0030] In practical use, when the inner liner block 14 moves, it can drive the sliding sleeve 15 to slide on the surface of the slide rail 16, which can limit the movement direction of the inner liner block 14.

[0031] Preferably, the end of the rotating rod 11 is fitted with a second sealed bearing 10 that is fitted onto the upper surface of the movable seat 9, and the surface of the rotating rod 11 is connected to a driven gear 17.

[0032] Preferably, the movable seat 9 is equipped with a first drive motor 18, and the output end of the first drive motor 18 is connected to a drive gear 19 that meshes with the driven gear 17.

[0033] In practical use, when the first drive motor 18 is running, it can drive the active gear disk 19 to rotate. When the active gear disk 19 rotates, it can drive the driven gear disk 17 to rotate through the meshing structure. The rotation of the driven gear disk 17 can drive the support plate 12 to rotate, thus realizing the transmission between the support plate 12 and the first drive motor 18.

[0034] Preferably, the ends of the three sets of threaded rods 7 are each connected to a pulley 20, and belt rings 21 are fitted onto the surfaces of the three pulleys 20. The ends of the threaded rods 7 are connected to the output end of the second drive motor 22 installed on the inner wall of the cooling pool 5.

[0035] In practical use, when the second drive motor 22 is running, it can drive the threaded rod 7 connected to it to rotate. When the threaded rod 7 rotates, it can drive the other two threaded rods 7 through the pulley 20 and belt ring 21. When the threaded rod 7 rotates, it can drive the threaded sleeve 8 to move longitudinally through the threaded connection, thereby realizing the height adjustment of the movable seat 9.

[0036] Working principle: When using this environmentally friendly slewing bearing precision controllable quenching equipment, first place the slewing bearing on the surface of the support plate 12 and fit it on the outside of the inner liner block 14. Then, the push rod 13 can be run. When the push rod 13 runs, it can squeeze the inner liner block 14 to move laterally. When the inner liner block 14 moves laterally to the inner wall of the slewing bearing, the position of the slewing bearing can be fixed at this time.

[0037] Then the second drive motor 22 can be controlled to run. When the second drive motor 22 runs, it can drive the threaded rod 7 connected to it to rotate and drive the other two threaded rods 7 to rotate through the pulley 20 and belt ring 21. When the threaded rod 7 rotates, it can move longitudinally through the movable seat 9. When the movable seat 9 moves longitudinally, it can drive the slewing bearing to move upward through the support plate 12 until it passes through the quenching heating ring 4. At this time, the slewing bearing can be heated and quenched through the quenching heating ring 4.

[0038] At the same time, the first drive motor 18 can be controlled to run. When the first drive motor 18 runs, it can drive the active gear disk 19 to rotate. When the active gear disk 19 rotates, it can exert a force on the support plate 12 through the driven gear disk 17. The support plate 12 is subjected to the force, which can drive the rotating rod 11 to rotate inside the second sealed bearing 10. When the support plate 12 rotates, it can drive the slewing bearing fixed on its surface to rotate. This can achieve uniform heating and quenching of the slewing bearing.

[0039] After the slewing bearing is quenched, the second drive motor 22 can be controlled to drive the threaded rod 7 connected to it to rotate in the opposite direction, and through the pulley 20 and belt ring 21, it can drive the other two threaded rods 7 to rotate in the opposite direction. When the threaded rod 7 rotates in the opposite direction, it can drive the threaded sleeve 8 to move downward. The downward movement of the threaded sleeve 8 can drive the movable seat 9 to move downward. The downward movement of the movable seat 9 can drive the slewing bearing to move downward through the support plate 12. When the slewing bearing moves downward into the water of the cooling pool 5, the slewing bearing can be cooled by the water.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
