Description

Technical Field

[0001] This utility model relates to the technical field of bearing repair, and in particular to a bearing cage deformation correction device. Background Technology

[0002] A cage is a bearing component that partially encloses all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guides and holds them within the bearing. During production and use, some cages may deform due to external forces and become unusable, requiring shape correction.

[0003] The existing Chinese utility model patent with application number CN202121294029.7 relates to a cage ellipticity correction device after welding, including a correction device body, groove, cage, fixed base, slot, threaded rod, handle and suction cup, etc. It can simultaneously correct the ellipticity of cages of different diameters, with high work efficiency, saving a lot of manpower, and can meet the needs of modern industrialization.

[0004] However, in actual use, the above-mentioned device cannot be directly inserted into the slot for correction of local curvature deformation of the cage. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bearing cage deformation correction device that provides stable support for the cage through a support device, corrects local areas of the cage through a correction device, and provides stable directional power to the correction device through a striking device, thereby improving the practicality of the device.

[0006] This utility model discloses a bearing cage deformation correction device, comprising a support device, a correction device, and a striking device. The correction device is mounted on the support device, and the striking device is mounted on the support device. The support device provides stable support for the cage, the correction device corrects a local area of ​​the cage, and the striking device provides stable directional power to the correction device, thereby improving the practicality of the device.

[0007] Preferably, the support device includes a support base, foot plates, side limiting blocks, and bolt slots. A set of foot plates is provided on the left and right sides of the lower end face of the support base, and an arc-shaped support surface is provided on the upper end face of the support base. A set of side limiting blocks is provided on the left and right sides, front and back, of the arc-shaped support surface. Multiple sets of bolt slots are provided on the upper end face of the foot plates. Bolts pass through the bolt slots to assist in fixing the foot plates. The arc-shaped support surface on the support base provides support to the outer side of the cage, facilitating the restoration of the cage's external support. The side limiting blocks provide lateral support to the cage, preventing it from tipping over, thus improving the stability and practicality of the device.

[0008] Preferably, the correction device includes a U-shaped impact block, an inner arc groove, an outer reinforcing rib, and an inner reinforcing rib. The lower end face of the U-shaped impact block is provided with an inner arc groove, the left and right outer sides of the U-shaped impact block are respectively provided with outer reinforcing ribs, and the lower left and right sides of the inner side of the U-shaped impact block are respectively provided with inner reinforcing ribs. The inner arc groove at the bottom of the U-shaped impact block is pressed onto the inner side of the cage. The outer and inner reinforcing ribs increase the support strength of the main body of the U-shaped impact block. By impacting the U-shaped impact block, the arc groove and the upper end face of the support seat match to correct the arc of the cage, thereby improving the practicality of the device.

[0009] Preferably, the striking device includes an impact plate, limiting rods, an inner limiting protrusion, a hand-holding groove, and a limiting slot. An inner limiting protrusion is located in the middle of the lower end face of the impact plate. A set of hand-holding grooves is located at the front and rear of the inner limiting protrusion. Two sets of limiting slots are located at the left and right sides of the upper end face of the U-shaped impact block. Four sets of limiting rods are located on the lower end face of the impact plate, with their positions corresponding to the positions of the multiple limiting slots. The impact plate is connected to the U-shaped impact block via the limiting rods and limiting slots. External force is used to impact the impact plate, providing impact power to the U-shaped impact block. The upper part of the U-shaped impact block is limited by the inner limiting protrusion and limiting rods. The hand-holding grooves facilitate the separation of the impact plate from the guide groove, improving the practicality of the device.

[0010] Preferably, it also includes side limiting guide rails and guide grooves. A set of side limiting guide rails is provided at the front and rear of the middle of the upper end face of the support base, and a set of guide grooves is provided at the lower part of the front and rear end faces of the U-shaped impact block. The side limiting guide rails can be inserted into the guide grooves on their upper sides. The lifting and lowering process of the U-shaped impact block is limited by the side limiting guide rails and guide grooves, and the impact force during the impact process is limited, so that the equipment can provide a stable force and improve the practicality of the device.

[0011] Preferably, the device also includes an internal threaded hole and a lower limit screw. The lower end face of the support base is provided with an internal threaded hole, and the upper part of the lower limit screw corresponds to the size of the circular hole on the cage. The lower limit screw extends through the internal threaded hole to the upper side of the support base. When correcting a cage with minor deformation, the lower limit screw can be rotated so that the upper part of the lower limit screw extends through the internal threaded hole to the upper side of the support base, thereby aligning and limiting the circular hole on the cage with the upper part of the lower limit screw. This reduces the rotational displacement of the cage itself during the repair process and improves the practicality and stability of the device.

[0012] Preferably, the device also includes an upper limit screw and an internal hexagonal groove. The upper end face of the internal arc groove is provided with an internal threaded hole. The upper part of the upper limit screw can be connected to the internal threaded hole on the internal arc groove. The lower end face of the upper limit screw is provided with an internal hexagonal groove. The lower part of the upper limit screw has the same size as the circular hole on the cage. By installing the upper limit screw in the internal threaded hole at the lower part of the internal arc groove, the lower part of the upper limit screw is inserted into the circular hole of the cage. This, together with the lower limit screw, assists in positioning the cage body, improving the stability and practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the support device provides stable support for the cage, the correction device corrects the local area of ​​the cage, and the striking device provides stable directional power for the correction device, thereby improving the practicality of the device.
