[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] The purpose of the utility model is to provide a backing bearing grinding tool for a tension bending straightening machine, so as to solve the problems existing in the above-mentioned related technologies and improve the grinding efficiency.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0047] Reference Figures 1 to 19This embodiment provides a backing bearing grinding tool for a tension and bending straightening machine, including a core shaft 3, an annular spacer, a locking nut, a driving structure and a supporting structure.

[0048] The core shaft 3 has a sleeve section and two threaded sections, with the sleeve section located between the two threaded sections. An annular pad is sleeved on the sleeve section, and multiple annular pads are arranged at intervals along the axial direction of the sleeve section. A backing bearing is placed between two adjacent annular pads, and the backing bearing is sleeved on the outside of the sleeve section with a gap between the sleeve section. Two locking nuts are respectively threadedly connected to the two threaded sections to ensure that the adjacent annular pads and the backing bearings are tightly against each other. The drive structure is in transmission connection with the first end of the core shaft 3 and is used to drive the core shaft 3 to rotate around its own axis. The support structure is rotatably connected to the second end of the core shaft 3 and is used to support the second end of the core shaft 3.

[0049] The annular gasket includes two end gaskets 5 located at both ends, and a plurality of intermediate gaskets 4 located between the two end gaskets 5. The annular gasket has a first inner side surface, an inner end surface, and a second inner side surface. The first inner side surface and the second inner side surface are coaxial, and the diameter of the first side surface is larger than the diameter of the second side surface. The first inner side surface is used to be sleeved on the outside of the adjacent backing bearing to radially position the backing bearing so that the annular gasket and the backing bearing are coaxial. The inner end surface is used to abut the end surface of the bearing outer ring of the adjacent backing bearing to axially position the backing bearing. The second inner side surface is used to be sleeved on the outside of the sleeve section to radially position the annular gasket so that the annular gasket and the core shaft 3 are coaxial.

[0050] The working principle of the backing bearing grinding tool of the tension and bending straightening machine in this embodiment is as follows:

[0051] By sleeve-mounting multiple backing bearings of the tension and bending straightening machine on the outside of the sleeve section and locking them at both ends with locking nuts, the inner end surface of the annular spacer is in close contact with the end surface of the adjacent backing bearing. The friction provided by this close contact position drives the outer ring of the backing bearing and the core shaft 3 to rotate synchronously. At this time, the multiple backing bearings can be polished simultaneously or separately through the corresponding polishing structure, thereby improving the polishing efficiency.

[0052] It should be noted that the inner ring of the backing bearing in this embodiment does not have a conventional interference fit with the core shaft 3, but rather a clearance, allowing the backing bearing to be quickly mounted on the core shaft 3, reducing assembly difficulty. The contact between the second inner side of the annular spacer and the sleeve section achieves radial positioning of the annular spacer, while the contact between the first inner side of the annular spacer and the outer side of the backing bearing also achieves radial positioning of the backing bearing. This ensures that the backing bearing remains coaxial with the core shaft 3 during rotation, ensuring that the inner ring of the backing bearing does not collide with the core shaft 3.

[0053] As a possible example, in this embodiment, the drive structure includes a speed-regulating motor 9 and a chuck 10. The speed-regulating motor 9 is in driving connection with the chuck 10, which is used to clamp the first end of the mandrel 3. The speed-regulating motor 9 can adjust the rotational speed of the chuck 10, thereby setting the corresponding speed according to actual grinding needs. The speed-regulating motor 9 is fixed to the speed-regulating motor mounting base 2, which is fixed to the base 1.

[0054] As a possible example, in this embodiment, the support structure includes a tip 6 and a first bearing seat 13. Tip 6 engages with the inner ring axial hole of the first bearing seat 13 and is used to press against the center hole of the second end of the mandrel 3. Tip 6 only provides center positioning and support for the second end of the mandrel 3 and does not provide rotational driving force.

[0055] As a possible example, in this embodiment, the backing bearing grinding tool of the tension bending straightening machine also includes a base 1, a slide rail 11 and a linear drive structure. The first bearing seat 13 is slidably mounted on the slide rail 11, the slide rail 11 is fixed on the slide rail fixing block 8, and the slide rail fixing block 8 is fixed on the base 1. The linear drive structure is transmission-connected to the first bearing seat 13 and is used to drive the first bearing seat 13 to slide along the slide rail 11. When in use, after the first end of the core shaft 3 is fixed, the top 6 is moved close to the second end of the core shaft 3 through the linear drive structure. After the top 6 abuts the second end of the core shaft 3, the axial position of the top 6 should be locked by a corresponding locking structure or by relying on the self-locking characteristics of the linear drive structure.

[0056] As a possible example, in this embodiment, there are two parallel slide rails 11, each of which has a slider slidably mounted on it. The first bearing seat 13 is fixedly connected to the connecting plate 7, and the two sliders are fixedly connected to each end of the connecting plate 7. The connecting plate 7 is in transmission connection with the linear drive structure.

[0057] As a possible example, in this embodiment, the linear drive structure includes a second bearing seat, a lead screw 12, and a lead screw drive structure. The second bearing seat is fixed to the base 1, and the polished rod section of the lead screw 12 engages with the inner ring axial hole of the second bearing seat. The lead screw 12 is threadedly connected to the connecting plate 7, and the lead screw drive structure is used to drive the lead screw 12 to rotate.

[0058] However, the actual implementation is not limited thereto. For example, the linear drive structure may also be other structures such as an electric telescopic rod, a hydraulic cylinder, etc.

[0059] As a possible example, in this embodiment, the screw drive structure is a hand wheel 14, and the end of the screw 12 away from the drive structure is connected to the hand wheel 14. The operator adjusts the axial position of the top 6 by rotating the hand wheel 14.

[0060] However, the actual implementation is not limited thereto. For example, the screw drive structure may also be a screw drive motor.

[0061] As a possible example, in this embodiment, the backing bearing grinding tool of the tension and bending straightening machine further includes a grinding structure, and the grinding structure is fixed on the base 1.

[0062] However, the actual implementation is not limited thereto. For example, the operator can also grind the backing bearing with a handheld grinding structure.

[0063] As a possible example, in this embodiment, the middle spacer 4 has two first inner side surfaces, two inner end surfaces and one second inner side surface. Both ends of the second inner side surface of the middle spacer 4 are connected to one first inner side surface via an inner end surface.

[0064] The end pad 5 has a first inner side surface, an inner end surface and a second inner side surface. One end of the second inner side surface of the end pad 5 is connected to the first inner side surface via the inner end surface.

[0065] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
