Description

Technical Field

[0001] This utility model relates to the technical field of bearing processing equipment, specifically a bearing raceway quenching device. Background Technology

[0002] Bearings are critical components in mechanical equipment, and the hardness and wear resistance of their raceways directly affect their service life and operational accuracy. Quenching is an important process for improving bearing raceway performance. By heating, holding, and cooling the raceway, the raceway surface achieves higher hardness and wear resistance. A search revealed that patent application number […].

[0003] CN202223398028.4 discloses a bearing raceway quenching device. This solution sets a chuck at the end of the rotary drive component to fix the bearing. A water supply hose and a heating element are set at the lower end of the telescopic component to achieve the quenching treatment of the bearing raceway. However, this solution still has certain defects and shortcomings in use. First, this solution can only quench one bearing at a time. After quenching, frequent unloading and loading are required, which is inefficient and not conducive to large-scale quenching of bearings. Second, although water seepage holes are opened on the worktable, moisture will still remain on the surface of the worktable, which has certain defects and shortcomings. Therefore, improvements are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bearing raceway quenching device, which solves the problems of existing quenching devices being able to process only one bearing at a time, having low processing efficiency, and having moisture residue on the workbench surface that affects the working environment.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A bearing raceway quenching device includes a worktable and a quenching assembly mounted on the worktable. A rotating ring is rotatably connected to the worktable, and an array of shafts are rotatably connected to the rotating ring along the circumferential direction. A chuck for clamping the bearing is fixedly connected to the upper end of each shaft, and a pinion is coaxially fixedly connected to the lower end of each shaft.

A first rotary drive component for driving the gear ring to rotate is mounted on the lower surface of the worktable.

[0009] Furthermore, the quenching assembly includes a quenching frame fixedly connected to the upper surface of the workbench, and a cylinder mounted on the quenching frame. The lower end of the cylinder output shaft is fixedly connected to a mounting base, and a heating element and a cooling water pipe are respectively provided on the mounting base.

[0010] Furthermore, a water storage tank is provided on the upper surface of the workbench on the side opposite to the quenching component, and an array of water guide grooves are provided on the upper surface of the rotating ring, with the height of the water guide grooves being flush with the water storage tank; a drainage bucket is fixedly connected to the inner wall of the rotating ring, and a drainage pipe is connected to the bottom of the drainage bucket.

[0011] Furthermore, the first rotary drive component includes a first rotary shaft rotatably connected to the lower surface of the worktable, and a drive gear coaxially fixedly connected to the first rotary shaft.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a bearing raceway quenching device, which has the following beneficial effects:

[0016] 1. This utility model, by setting up a rotating ring and an array of chucks, can cooperate with the first rotary drive component to drive the rotating ring to rotate, realizing simultaneous operation of multiple stations. When a bearing is being heated and cooled under the quenching component, the operator can load or unload materials at other stations, greatly reducing waiting time and significantly improving production efficiency, which is suitable for large-scale bearing processing needs. Through the intermittent meshing structure of the irregular gear and the pinion of the second rotary drive component, precise rotation control of the bearing during the quenching process is realized: when the bearing is in the quenching station, the toothed part of the irregular gear meshes with the pinion, driving the shaft and chuck to rotate, so that the raceway is uniformly heated and cooled. When the rotating ring switches stations, the notch of the irregular gear corresponds to the pinion, stopping the rotation drive and avoiding interference, so that the rotating ring can rotate normally, ensuring smooth station switching, improving quenching uniformity and process stability.

[0017] 2. This utility model, by fixing a drainage bucket to the inner wall of the rotating ring, and opening a water storage tank on the worktable, and opening a water guide groove on the upper surface of the rotating ring, allows the water generated during quenching to enter the water storage tank and the drainage bucket. The water in the water storage tank will enter the drainage bucket through the water guide groove, thus achieving effective collection of cooling water and preventing water accumulation on the worktable. The drainage bucket also prevents the cooling water from contacting gears, gear rings, etc., achieving a certain protective effect. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Example

[0026] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention provides a bearing raceway quenching device, including a worktable 1 and a quenching assembly 5 mounted on the worktable 1. The worktable 1 is the basic load-bearing structure of the device. The quenching assembly 5 performs quenching treatment on the bearing raceway. A rotating ring 2 is rotatably connected to the worktable 1. The rotating ring 2 can rotate along the central axis of the worktable 1, and an array of shafts 11 are rotatably connected to the rotating ring 2 in the circumferential direction. The shafts 11 are rotatable. A chuck 3 for clamping bearings is fixedly connected to the upper end of the shafts 11. The chuck 3 is used to clamp the bearing to be processed, and a pinion 12 is coaxially fixedly connected to the lower end of the shafts 11. The setting 2 is used to drive the shaft 11 to rotate, which in turn drives the chuck 3 to rotate, thereby adjusting the angle of the bearing to be processed and performing quenching treatment at various angles of the bearing raceway. The lower surface of the worktable 1 is equipped with a second rotary drive component 9 for driving the pinion 12 to rotate, thereby realizing the rotary drive of the pinion 12. The lower surface of the rotating ring 2 is fixedly connected with a gear ring 13, and the lower surface of the worktable 1 is equipped with a first rotary drive component 8 for driving the gear ring 13 to rotate. The first rotary drive component 8 can drive the gear ring 13 to rotate, thereby realizing the rotary drive of the rotating ring 2, which drives the bearing to be processed to rotate circumferentially, facilitating the batch processing of bearings.

[0027] like Figure 2 As shown, in some embodiments, the quenching assembly 5 includes a quenching frame 501 fixedly connected to the upper surface of the workbench 1, and a cylinder 502 mounted on the quenching frame 501. The lower end of the output shaft of the cylinder 502 is fixedly connected to a mounting base 503, and a heating element 504 and a cooling water pipe 505 are respectively provided on the mounting base 503.

[0028] It should be noted that the quenching rack 501 is fixed on the workbench 1, the cylinder 502 drives the mounting base 503 to rise and fall, the heating element 504 (which can be an induction heating coil) at the bottom of the mounting base 503 heats the bearing raceway, and the cooling water pipe 505 sprays out coolant after heating for quenching.

[0029] like Figure 1 and Figure 3 As shown, in some embodiments, a water storage tank 6 is provided on the side of the upper surface of the workbench 1 opposite to the quenching component 5, and an array of water guide grooves 4 are provided on the upper surface of the rotating ring 2, the height of the water guide grooves 4 being flush with the water storage tank 6; a drainage bucket 7 is fixedly connected to the inner wall of the rotating ring 2, and a drainage pipe 10 is connected to the bottom of the drainage bucket 7.

[0030] It should be noted that during the quenching process, cooling water is sprayed out through the cooling water pipe 505. The cooling water enters the water storage tank 6 and the drainage hopper 7 through the gap at the bottom of the chuck 3. The height of the water guide trough 4 is flush with that of the water storage tank 6, so that the water in the water storage tank 6 enters the drainage hopper 7 through the water guide trough 4, realizing the collection of accumulated water and avoiding water residue on the workbench 1.

[0031] like Figure 3 and Figure 4 As shown, in some embodiments, the first rotary drive component 8 includes a first rotary shaft 801 rotatably connected to the lower surface of the worktable 1, and a drive gear 802 coaxially fixedly connected to the first rotary shaft 801. The drive gear 802 meshes with the gear ring 13, and a first motor 804 is mounted on a first mounting bracket 803 fixedly connected to the lower surface of the worktable 1. One side of the first motor 804 is coaxially connected and fixed to the first rotary shaft 801.

[0032] It should be noted that the first motor 804 in the first rotary drive component 8 is fixed below the worktable 1 by the first mounting bracket 803, and its output shaft is connected to the first rotary shaft 801. The drive gear 802 on the first rotary shaft 801 meshes with the gear ring 13 on the lower surface of the rotating ring 2. Starting the first motor 804 can drive the rotating ring 2 to rotate, thereby realizing the switching of work positions.

[0033] like Figure 3 and Figure 5 As shown, in some embodiments, the second rotary drive component 9 includes a second rotary shaft 901 rotatably connected to the lower surface of the worktable 1, and a non-circular gear 902 coaxially fixedly connected to the second rotary shaft 901. The non-circular gear 902 is adapted to the pinion 12, and a notch 905 is provided on one side of the non-circular gear 902. The second rotary drive component 9 also includes a second mounting bracket 904 fixedly connected to the lower surface of the worktable 1, and a second motor 903 is mounted on the second mounting bracket 904. One side of the second motor 903 is coaxially connected and fixed to the second rotary shaft 901.

[0034] It should be noted that the irregular gear 902 on the second rotating shaft 901 intermittently meshes with the pinion 12. When the irregular gear 902 rotates, the toothed part drives the pinion 12 to rotate, thereby driving the rotation of the shaft 11 and the chuck 3, and then driving the bearing to rotate. When it is necessary to control the rotation of the rotating ring 2, the notch 905 of the irregular gear 902 is opposite to the pinion 12 and there is no interference. The irregular gear 902 does not contact the pinion 12. At this time, the presence of the irregular gear 902 will not affect the normal rotation of the rotating ring 2.

[0035] The working principle and usage steps of this utility model are as follows: First, the operator fixes the bearing to be quenched into multiple chucks 3 on the rotating ring 2 to complete the initial loading. Then, the first motor 804 is started, which drives the rotating ring 2 to rotate through the meshing relationship between the drive gear 802 and the gear ring 13, moving the first bearing workpiece directly below the quenching assembly 5 and then stopping. After that, the cylinder 502 extends, driving the mounting base 503 to descend, so that the heating element 504 is close to the bearing raceway, and the heating element 504 is started to heat the raceway. At the same time, the second motor 903 is started, and the toothed part of the special gear 902 meshes with the pinion 12, driving the shaft 11 and the chuck 3 to rotate, ensuring uniform heating of the raceway. After completion, the heating element 504 stops working, and the cooling water pipe 505 sprays coolant to quench and cool the raceway. The bearing continues to rotate to ensure uniform cooling. Wastewater is discharged through the water storage tank 6, the water guide tank 4, the drainage hopper 7, and the drainage pipe 10. After the quenching treatment of the bearing is completed, the notch 905 of the special gear 902 corresponds to the pinion 12 and will not touch, so that the rotating ring 2 can rotate normally in the circumferential direction. After cooling is completed, the cylinder 502 retracts and resets, the first motor 804 starts again, and the rotating ring 2 rotates to move the next bearing workpiece to the bottom of the quenching component 5. At the same time, the operator can unload materials and load new bearings at the workstation that has been quenched, realizing continuous cycle operation.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is 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.
