Description

Technical Field

[0001] This utility model belongs to the field of bearing manufacturing technology, and in particular relates to a bearing ring annealing tool. Background Technology

[0002] Bearing rings are annular parts of radial rolling bearings with one or more raceways. During the production of bearing rings, they undergo high-temperature quenching, followed by annealing. During annealing, the bearing rings are placed in a hopper, which then enters the annealing furnace. Bearing rings are typically stacked neatly in the hopper, usually with adjacent parts placed against each other. However, in practice, this is usually done manually, followed by hoisting onto the conveyor line of the annealing furnace. During hoisting, the hopper inevitably shakes, causing the bearing rings to shift, leading to collapse or collision of the stacked rings, which is detrimental to ensuring the annealing effect of individual bearing rings. Therefore, existing bearing ring annealing hoppers still suffer from inconvenient stacking and poor ring positioning. Utility Model Content

[0003] In view of this, the present invention aims to provide a bearing ring annealing fixture to solve the problem of inconvenient ring stacking in existing material boxes.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A bearing ring annealing fixture includes a bearing housing and a locator. The bearing housing includes a housing body, a detachable cover plate on top of the housing body, and a support member slidably installed inside the housing body. The locator is detachably installed inside the housing body and includes a vertical end at the top and a horizontal end at the bottom. The cover plate is provided with a positioning groove that can cooperate with the vertical end of the locator. At least two support members are provided at intervals, and there is a receiving gap between two adjacent support members for accommodating the locator and the bearing ring. One end of the support member extending into the housing body is provided with a protrusion for supporting the bearing ring. There is an insertion gap between the protrusion and the bottom surface of the housing body that can cooperate with the horizontal end of the locator. There is a through gap between the protrusions of two adjacent support members to facilitate the passage of the horizontal end of the locator. The insertion gap communicates with the receiving gap through the through gap.

[0005] Furthermore, the support member is provided with a locking screw, and the housing is provided with a strip-shaped hole that mates with the locking screw. The length direction of the strip-shaped hole is the same as the sliding direction of the support member.

[0006] Furthermore, the horizontal end of the locator is provided with a detachable extension block.

[0007] Furthermore, both the horizontal end of the locator and the extension block are provided with beveled surfaces to facilitate insertion into the mating gap.

[0008] Furthermore, the vertical end of the locator is provided with an extension plate. At least two extension plates are evenly arranged along the circumference of the locator. One end of each extension plate is installed on the vertical end of the locator by a fixing screw, and the other end is provided with a fitting part that can fit against the inner wall of the collar.

[0009] Furthermore, the extension plate is provided with an elongated hole that mates with the fixing screw, and the vertical end of the locator is provided with a threaded hole that mates with the fixing screw. The length direction of the elongated hole is the same as the radial direction of the bearing ring.

[0010] Furthermore, the vertical end of the positioner is provided with a conical end that mates with the positioning groove.

[0011] Furthermore, the vertical end of the positioner is also provided with a lifting hole.

[0012] Compared with the prior art, the bearing ring annealing bearing fixture of this utility model has the following advantages: This utility model discloses a bearing ring annealing support fixture, applicable to the annealing treatment of bearing rings. With simple adjustments, it can be used to support bearing rings of different diameters, offering advantages such as high load-bearing capacity, good applicability, and versatility. By fitting the bearing ring onto the locator, which, in conjunction with support members, achieves positioning and fixation of the ring, the outer side of the ring is limited by the receiving gap formed by the two support members, while the inner side is limited by the locator. This improves the stability of the bearing ring during housing movement or annealing, preventing ring movement and ensuring the annealing effect. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A bearing ring annealing support fixture, such as Figures 1 to 4As shown, the device includes a carrier box and a locator 4. The carrier box includes a box body 1, a detachable cover plate 2 on top of the box body 1, and a support member 5 slidably installed inside the box body 1. The locator 4 is detachably installed inside the box body 1 and includes a vertical end at the top and a horizontal end at the bottom. The cover plate 2 is provided with a positioning groove 3 that can cooperate with the vertical end of the locator 4. At least two support members 5 are provided at intervals, and there is a receiving gap 12 between two adjacent support members 5 for accommodating the locator 4 and the collar 7. One end of the support member 5 that extends into the box body 1 is provided with a protrusion 9 for supporting the collar 7. There is an insertion gap 10 between the protrusion 9 and the bottom surface of the box body 1 that can cooperate with the horizontal end of the locator 4. There is a through gap 11 between the protrusions 9 of two adjacent support members 5 to facilitate the passage of the horizontal end of the locator 4. The insertion gap 10 is connected to the receiving gap 12 through the through gap 11.

[0020] Specifically, the vertical end of the locator 4 is also provided with a lifting hole 14. The bearing ring 7 can be fitted onto the locator 4. The horizontal end of the locator 4 can hold the lowest bearing ring 7, while the vertical end of the locator 4 can engage with the inner side of the bearing ring 7. Multiple bearing rings 7 can be fitted onto one locator 4 and lifted using hoisting equipment, which helps improve the efficiency of picking up and placing batches of bearing rings 7. Simultaneously, by fitting the bearing ring 7 onto the locator 4, the locator 4 can also cooperate with the support member 5 to limit and fix the bearing ring 7. The outer side of the bearing ring 7 is limited by the receiving gap 12 formed by the two support members 5, while the inner side can be limited by the locator 4, improving the stability of the bearing ring 7 during movement of the housing 1 or annealing treatment.

[0021] In practical applications, the vertical end of the positioner 4 is provided with a conical end 13 that mates with the positioning groove 3. The cover plate 2 can be detachably installed on the housing 1 using conventional methods such as hook and latch locks, and the cover plate 2 can be provided with a groove that mates with the housing 1 to improve the stability of the cover plate 2 after installation. By using the positioning groove 3 on the cover plate 2 to engage with the vertical end of the positioner 4 and the engagement gap 10 to engage with the horizontal end of the positioner 4, the upper and lower ends of the positioner 4 can be limited, thereby ensuring that the positioner 4 remains stable within the housing 1, so that the positioner 4 can always stably limit the movement of the collar 7 and prevent the collar 7 from moving.

[0022] Preferably, the support member 5 is provided with locking screws 8, and the housing 1 is provided with a strip hole 6 that mates with the locking screws 8. The length direction of the strip hole 6 is the same as the sliding direction of the support member 5. Specifically, two locking screws 8 are provided on the left and right sides of the support member 5, and the left and right sides of the housing 1 are provided with edges for installing the locking screws 8, with the strip hole 6 located on the edges. In actual use, the support member 5 is provided with screw holes that mate with the locking screws 8. The locking screws 8 are connected to the support member 5 by passing through the strip hole 6, which can achieve the limiting and fixing of the support member 5. Similarly, by loosening the locking screws 8 and moving the support member 5 along the strip hole 6, the support member 5 can move stably under the sliding guidance of the locking screws 8 and the strip hole 6, thereby realizing the adjustment of the size of the accommodating gap 12. By adjusting the size of the accommodating gap 12, it can better accommodate bearing rings 7 of different diameters, ensuring that the protrusions 9 on the support member 5 can always stably support bearing rings 7 of different diameters.

[0023] In practical applications, the horizontal end of the positioner 4 is equipped with a detachable extension block 18. The extension block 18 can be fixed to the positioner 4 with screws. Both the horizontal end of the positioner 4 and the extension block 18 are provided with beveled portions 19 to facilitate insertion into the mating gap 10. By using a detachable installation method for the extension block 18, the operator can select an appropriate length of extension block 18 according to the diameter of the bearing race 7, ensuring that the horizontal end of the positioner 4 can support bearing races 7 with larger diameters. In addition, by providing beveled portions 19 on the extension block 18 and the horizontal end of the positioner 4, the horizontal end of the positioner 4 and the extension block 18 can be easily inserted into the mating gap 10 when the operator rotates the positioner 4.

[0024] Preferably, the vertical end of the locator 4 is provided with an extension plate 15. At least two extension plates 15 are evenly arranged along the circumference of the locator 4. One end of each extension plate 15 is mounted on the vertical end of the locator 4 by a fixing screw 16, and the other end has a fitting portion that can fit against the inner wall of the collar 7. Specifically, two or more extension plates 15 can be evenly arranged, and the fitting portion can be an arc surface to reduce the contact area between the fitting portion and the inner wall of the collar 7. The fixing screws 16 can be spaced two, three, or more along the vertical direction to ensure the connection strength between the extension plate 15 and the vertical end of the locator 4, ensuring that the extension plate 15 can stably press against the inner side of the collar 7, thereby limiting and fixing the collar 7 and preventing it from collapsing or moving.

[0025] In practical applications, the extension plate 15 has an elongated hole 17 that mates with the fixing screw 16, and the vertical end of the positioner 4 has a threaded hole that mates with the fixing screw 16. The length direction of the elongated hole 17 is the same as the radial direction of the bearing ring 7. For example, a connecting plate 21 is fixed to the vertical end of the positioner 4, and the extension plate 15 has a connecting groove 20 that mates with the connecting plate 21. The elongated hole 17 communicates with the connecting groove 20. By loosening the fixing screw 16, the operator can easily slide and adjust the position of the extension plate 15 along the elongated hole 17 to accommodate bearing rings 7 of different diameters. Furthermore, if necessary, the operator can also replace the extension plate 15 with one of suitable length, further improving the adaptability of this positioner 4 to bearing rings 7 of different diameters.

[0026] The following methods can be used when employing this type of load-bearing fixture: After the operator places the bearing race 7 onto the vertical end of the locator 4, the locator 4 can be hoisted into the housing 1 using hoisting equipment. The horizontal end of the locator 4 will then pass through the receiving gap 12 and the through gap 11 until it abuts against the bottom surface of the housing 1. Afterward, the locator 4 can be rotated to insert its horizontal end and extension block 18 into the insertion gap 10. The insertion gap 10, in conjunction with the horizontal end or insertion block of the locator 4, effectively limits and fixes the lower end of the locator 4. It should be noted that the installation position of the locator 4 may differ for bearing races 7 of different diameters. To ensure the fit between the vertical end of the locator 4 and the positioning groove 3 on the cover plate 2, a cover plate 2 with a suitable positioning groove 3 should be selected for installation. Alternatively, multiple positioning grooves 3 at different positions can be machined on a single cover plate 2. Compared to replacing the entire housing and locator 4, replacing or machining only the cover plate 2 is less costly and will not significantly affect actual use.

[0027] After the bearing ring 7 has been annealed, the operator can first open the cover plate 2, then use the hoisting equipment to hoist the positioner 4 to the flat ground outside the housing 1, and finally lay down the positioner 4 and pull it out to separate the positioner 4 from the ring 7. The operation is relatively simple.

[0028] This utility model discloses a bearing ring annealing support fixture, applicable to the annealing treatment of bearing rings. With simple adjustments, it can be used to support bearing rings of different diameters, offering advantages such as high load-bearing capacity, good applicability, and versatility. By fitting the bearing ring onto the locator, which, in conjunction with support members, achieves positioning and fixation of the ring, the outer side of the ring is limited by the receiving gap formed by the two support members, while the inner side is limited by the locator. This improves the stability of the bearing ring during housing movement or annealing, preventing ring movement and ensuring the annealing effect.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
