Description

Technical Field

[0001] This invention relates to the field of bearing heat treatment technology, and more specifically, to a heat treatment apparatus for bearing races. Background Technology

[0002] In order to improve the hardness and strength of bearing steel during the production and processing of bearings, heat treatment processes can ensure the consistency of bearing materials, thereby improving the overall mechanical system's operating performance and durability.

[0003] In the prior art, patent CN119351715B discloses a heat treatment device for robot bearings. The device vibrates the bearing ring by moving the hook up and down. However, the vibration force generated on the bearing ring is low and cannot completely shake off the carbides. The carbides are easy to remain on the bearing ring, which affects the heat treatment effect and the bearing quality. Summary of the Invention

[0004] To address the above deficiencies, the present invention provides a heat treatment apparatus for bearing rings, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heat treatment apparatus for bearing rings, comprising: frame; The heat treatment chamber is raised and lowered along the frame; A linear drive element drives the heat treatment chamber to move up and down; The chamber door is located below the heat treatment chamber; The vibration frame includes a support side plate fixedly connected to one side of the box door surface. A cavity is provided in the center of the support side plate, and a vibration block is movably arranged in the cavity. Vibration plates are fixedly connected to both sides of the vibration block, and the inner side of the vibration plate is in contact with the support side plate. Among them, a number of support rods are fixedly connected to the vibration plate on one side, and a number of support springs are horizontally connected to each support rod. The bearing ring is sleeved on the support rod and its inner wall is in contact with the support spring. A spacer plate is provided between adjacent support springs, and the bottom end of the spacer plate is fixedly connected to the support rod.

[0006] Furthermore, one end of the supporting spring is fixedly connected to the supporting rod in the extending direction, and a gap is left between the other end and the supporting rod. Both ends of the supporting spring along its extending direction are chamfered to avoid collision damage to the bearing ring.

[0007] Furthermore, the vibration frame also includes several fixed side plates, one end of which is fixedly connected to the support side plate. The fixed side plate is located above one side of the support rod and is set at an angle so that the surface of the fixed side plate faces the support rod. The fixed side plate facing the support rod is connected to an outer ceramic pad, and the surface of the support spring is connected to an inner ceramic pad. The surfaces of the outer ceramic pad and the inner ceramic pad are both arc-shaped, so as to polish the outer wall and the inner wall of the bearing ring respectively.

[0008] The bearing ring is rubbed against its inner and outer walls by the outer and inner ceramic pads. The vibration and friction can cause the carbides to crack and peel off, completely eliminating the carbides. At the same time, it can remove the burrs on the bearing ring and give the bearing ring surface a uniform metallic luster, improving the quality of the bearing. The bearing ring rises and contacts the outer ceramic pad, which can apply a tangential force to the bearing ring, causing the bearing ring to rotate to one side, so as to uniformly and completely polish the bearing ring.

[0009] Furthermore, a support frame is fixedly connected to the bottom of the heat treatment box. The support side plate has an upper guide hole at the upper end of the cavity and a lower guide hole at the lower end of the cavity. The bottom end of the lower guide hole communicates with the box door. An upper guide post is connected to the top of the vibrating block and is inserted into the upper guide hole. A lower guide post is connected to the bottom of the vibrating block. A guide rod is fixedly connected between the support frame and the box door. A vibrating seat is movably connected to the guide rod. The bottom end of the lower guide post passes through the lower guide hole and is fixedly connected to the vibrating seat. A vibration motor is installed on the vibrating seat. A spring is fitted on the guide rod and is located below the vibrating seat.

[0010] Furthermore, two support rods are installed on the support side plate. The two support rods are located on both sides below the vibrating plate. The two support rods are provided with support trays. Connectors are installed at both ends of the support trays and are movably connected to the support rods.

[0011] The carbides are collected by a support tray to prevent them from scattering into the heat treatment chamber. The support tray is connected to the support rod by a connector, which makes it easy to disassemble and assemble the support tray and to retrieve the carbides.

[0012] Furthermore, a feeding plate is fixedly connected to one side of the box door, and the feeding plate is rotatably connected to the frame via a rotating shaft. A first hinge is installed on the other side of the box door, and a second hinge is installed on one side of the frame. A cylinder is hinged between the second hinge and the first hinge.

[0013] The cylinder drives the box door and the unloading plate to rotate along the shaft, causing the vibrating frame to tilt. The vibration of the vibrating frame causes the bearing rings to fall from the support rod onto the unloading plate, making it easier to unload the bearing rings without having to manually pick them up one by one, thus improving work efficiency and preventing burns to workers.

[0014] Furthermore, a heat insulation frame is fixedly connected to the top of the heat treatment box, and a linear drive element is connected to the frame, with the output end of the linear drive element fixedly connected to the heat insulation frame.

[0015] The heat from the heat treatment chamber is insulated by a heat shield to prevent high temperatures from damaging the linear drive components.

[0016] Furthermore, the frame is provided with guide grooves on both sides, and heat insulation guides are fixedly connected to both sides of the heat treatment box. The end of the heat insulation guide away from the heat treatment box is slidably connected to the guide groove.

[0017] The heat treatment chamber is guided by heat-insulating guides and guide grooves to prevent it from shifting position.

[0018] The beneficial effects of this invention are: 1. The vibrating block drives the vibrating plate and support rod to vibrate up and down. The bearing ring vibrates on the support spring. The vibration shakes off the carbides produced during heat treatment. At the same time, the bearing ring can change position on the support spring. The support spring can repeatedly tap the bearing ring. The bearing ring can change position and shake off the carbides. The bearing ring will not always be in contact with the support spring in the same position. The carbides will not block the bearing ring, so the bearing ring is heated more evenly and the heat treatment effect is improved. 2. When the bearing ring falls and contacts the support spring, the support spring can bend to reduce the impact force on the bearing ring and avoid damage to the bearing ring.

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] This application provides a heat treatment apparatus for bearing rings. Please refer to [link / reference]. Figures 1-7 Includes rack 1; Heat treatment chamber 2 is raised and lowered along frame 1; Linear drive element 3 drives the heat treatment box 2 to move up and down; Box door 4 is located below heat treatment box 2; The vibration frame 5 includes a support side plate 501 fixedly connected to one side of the surface of the box door 4. A cavity 502 is provided at the center of the support side plate 501. A vibration block 503 is movably arranged in the cavity 502. Vibration plates 504 are fixedly connected to both sides of the vibration block 503. The inner side of the vibration plate 504 is in contact with the support side plate 501. Among them, several support rods 505 are fixedly connected to the vibrating plate 504 on one side, and several support springs 506 are horizontally connected to each support rod 505. The bearing ring is sleeved on the support rod 505 and its inner wall is in contact with the support springs 506. A spacer plate 507 is provided between adjacent support springs 506, and the bottom end of the spacer plate 507 is fixedly connected to the support rod 505.

[0022] In practical applications, the heat treatment chamber 2 is driven to rise and fall by the linear drive element 3. After the heat treatment chamber 2 rises, the bearing rings that need to be heat treated are placed on the support rod 505. The inner wall of the bearing rings contacts the support spring 506. The two adjacent bearing rings are separated by the partition plate 507 so that each bearing ring is located on the support spring 506. The linear drive element 3 drives the heat treatment chamber 2 to fall. The bottom of the heat treatment chamber 2 fits against the chamber door 4. The bearing rings are heat treated by the heat treatment chamber 2. During the heat treatment process, the vibrating block 503 vibrates up and down in the cavity 502 of the supporting side plate 501. The vibrating block 503 drives the vibrating plate 504 and the supporting rod 505 to vibrate up and down. The bearing ring vibrates on the supporting spring 506. The vibration shakes off the carbides generated during the heat treatment. At the same time, it can change the position of the bearing ring on the supporting spring 506. The supporting spring 506 can repeatedly tap the bearing ring. The bearing ring can change its position and shake off the carbides. The bearing ring will not always be in contact with the supporting spring 506 in the same position. The carbides will not block the bearing ring, making the bearing ring heat more evenly and improving the heat treatment effect.

[0023] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 One end of the support spring 506 is fixedly connected to the support rod 505 in the extension direction, and the other end is left with a gap between it and the support rod 505. Both ends of the support spring 506 along its extension direction are chamfered to avoid collision damage to the bearing ring.

[0024] In practical applications, the bearing ring is located on the support spring 506. When the bearing ring is subjected to vibration, it will vibrate up and down. There is a gap between one end of the support spring 506 and the support rod 505. When the bearing ring falls, the support spring 506 can bend to reduce the impact on the bearing ring. In addition, the chamfer prevents the bearing ring from being damaged by bumps.

[0025] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 3 The vibration frame 5 also includes several fixed side plates 508. One end of the fixed side plate 508 is fixedly connected to the support side plate 501. The fixed side plate 508 is located above one side of the support rod 505 and is set at an angle so that the surface of the fixed side plate 508 faces the support rod 505. An outer ceramic pad 509 is connected to the side of the fixed side plate 508 facing the support rod 505, and an inner ceramic pad 510 is connected to the surface of the support spring 506. The surfaces of the outer ceramic pad 509 and the inner ceramic pad 510 are both arc-shaped, so as to polish the outer wall and inner wall of the bearing ring respectively.

[0026] In practical applications, when the bearing ring moves upward, its sidewall contacts the outer ceramic pad 509 on the fixed side plate 508, rubbing against the outer wall of the bearing ring. After the bearing ring moves downward, it contacts the inner ceramic pad 510 on the support spring 506, rubbing against the inner wall of the bearing ring. The vibration and friction can cause cracks and peeling of carbides, completely eliminating the generated carbides and removing burrs from the bearing ring, resulting in a uniform metallic luster on the bearing ring surface and improving the quality of the bearing. When the bearing ring rises and contacts the outer ceramic pad 509, the outer ceramic pad 509 can apply a tangential force to the bearing ring, causing it to rotate to one side, which can evenly and completely polish the bearing ring.

[0027] Refer to the instruction manual appendix Figure 4 Included with instruction manual Figure 5 A support frame 6 is fixedly connected to the bottom of the heat treatment box 2. The support side plate 501 has an upper guide hole 7 at the upper end of the cavity 502 and a lower guide hole at the lower end of the cavity 502. The bottom end of the lower guide hole is connected to the box door 4. The top of the vibrating block 503 is connected to an upper guide post 9, which is inserted into the upper guide hole 7. The bottom end of the vibrating block 503 is connected to a lower guide post 10. A guide rod 11 is fixedly connected between the support frame 6 and the box door 4. A vibrating seat 12 is movably connected to the guide rod 11. The bottom end of the lower guide post 10 passes through the lower guide hole and is fixedly connected to the vibrating seat 12. A vibration motor 13 is installed on the vibrating seat 12. A spring 14 is fitted on the guide rod 11 and is located below the vibrating seat 12.

[0028] In practical applications, the vibration motor 13 starts working, and the vibration seat 12 vibrates up and down along the guide rod 11 through the vibration motor 13 and the spring 14. The vibration seat 12 drives the vibration block 503 to vibrate up and down through the guide column 10. The vibration block 503 drives the upper guide column 9 to move in the upper guide hole 7. The upper guide column 9 and the upper guide hole 7 guide the vibration block 503. The vibration block 503 drives the vibration plate 504, the support rod 505 and the bearing ring to vibrate. The vibration motor 13 drives the vibration frame 5 to vibrate intermittently.

[0029] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 Two support rods 15 are installed on the support side plate 501. The two support rods 15 are located on both sides below the vibrating plate 504. The two support rods 15 are provided with support trays 16. Connectors 17 are installed at both ends of the support trays 16. The connectors 17 are movably connected to the support rods 15.

[0030] In practical applications, the fallen carbides fall onto the support tray 16, which collects the carbides and prevents them from scattering into the heat treatment chamber 2. The support tray 16 is connected to the support rod 15 via the connector 17, making it easy to disassemble and assemble the support tray 16, and easy to pick up and collect the carbides.

[0031] Refer to the instruction manual appendix Figure 6 Included with instruction manual Figure 7 A feeding plate 18 is fixedly connected to one side of the box door 4. The feeding plate 18 is rotatably connected to the frame 1 via a rotating shaft. A first hinge 19 is installed on the other side of the box door 4. A second hinge 20 is installed on one side of the frame 1. A cylinder 21 is hinged between the second hinge 20 and the first hinge 19.

[0032] In practical applications, after heat treatment, the heat treatment chamber 2 rises first, completely exposing the vibrating frame 5. The cylinder 21 starts working, and the output end of the cylinder 21 extends in, causing the chamber door 4 and the unloading plate 18 to rotate along the shaft, causing the vibrating frame 5 to tilt. The vibration motor 13 drives the vibrating frame 5 to vibrate, which can cause the bearing rings to fall from the support rod 505 onto the unloading plate 18, making it convenient to unload the bearing rings. This eliminates the need for manual handling, improves work efficiency, and avoids burns to workers.

[0033] Refer to the instruction manual appendix Figure 5 Included with instruction manual Figure 6 A heat insulation frame 8 is fixedly connected to the top of the heat treatment box 2. A linear drive element 3 is connected to the frame 1, and the output end of the linear drive element 3 is fixedly connected to the heat insulation frame 8.

[0034] In practical applications, the heat is isolated from the heat treatment box 2 by the heat insulation frame 8 to prevent high temperature from damaging the linear drive element 3.

[0035] Refer to the instruction manual appendix Figure 5 Included with instruction manual Figure 6 The frame 1 is provided with guide grooves 22 on both sides, and heat insulation guides 23 are fixedly connected to both sides of the heat treatment box 2. The end of the heat insulation guide 23 away from the heat treatment box 2 is slidably connected to the guide grooves 22.

[0036] In practical applications, when the heat treatment box 2 is raised or lowered, the heat treatment box 2 drives the heat insulation guide 23 to slide along the guide groove 22. The heat insulation guide 23 and the guide groove 22 guide the heat treatment box 2 to prevent the position of the heat treatment box 2 from shifting.
