[0002] The continuous casting roller is the core component of the continuous casting machine, and it plays a vital role in the production process of the continuous casting machine. After the continuous casting roller is used for a cycle and is offline, it is found that the bottom surface sealing part of the bearing seat has defects such as bottom surface corrosion, pits, and wear due to long-term corrosion and wear, which reduces the center height of the bearing seat, resulting in inconsistent center height dimensions of the same set of roller bearing seats, causing water leakage and seepage in the bottom seal of the bearing seat, etc. This situation will seriously affect the replacement cycle and service life of the continuous casting roller, so it is necessary to repair the continuous casting roller bearing seat. Traditional bearing installation methods may be time-consuming, while auxiliary devices can improve installation efficiency and save time and human resources. However, some existing repair devices mainly rely on manual fixing of the bearing seat during use, which will relatively use more manpower and material resources, and are costly, complicated to operate, and not easy to promote. Therefore, whether it is possible to improve a new type of auxiliary device and repair method for repairing the continuous casting roller bearing seat that is easy to operate, low cost, and reduces the use of human resources is a technical problem to be solved by the present invention.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0024] It should be noted that in the present application, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0025] like Figure 1-6 As shown, a novel auxiliary device for repairing a continuous casting roller bearing seat includes a rotating support, a vibration module, a support plate 27 and a clamping assembly.

[0026] The rotating support is placed on a workbench and is used to support and position the repair device; the vibration module is vertically and rotatably installed on the top of the rotating support and is used to vibrate the support plate 27 and the clamping assembly installed on the top of the support plate 27 to eliminate the stress of the continuous casting roller bearing seat placed on the clamping assembly; the support plate 27 is fixed above the vibration module; the clamping assembly is installed on the support plate 27, and the clamping assembly includes a handle 36 and two limit plates. By rotating the clamping assembly, the distance between the two limit plates is reduced, so that the two limit plates clamp the continuous casting roller bearing seat.

[0027] The rotating support includes a base 1 and positioning plates 2 welded and mounted on both sides of the base 1. The thickness of the two positioning plates 2 is less than the thickness of the base 1, and a plurality of third through holes 7 are provided on the two positioning plates 2. Bolts can be used to penetrate the third through holes 7 to the workbench, or a heavy object can be used to press on the positioning plates 2 to limit the overall position of the auxiliary device for repair.

[0028] A first through hole 3 is formed through the center of the base 1. An annular groove 4 is also formed on the base 1. The center of the annular groove 4 is at the same position as the center of the first through hole 3. The annular groove 4 is formed around the first through hole 3. A limited bearing seat 5 is installed on the first through hole 3, and the vibration module can be rotatably installed on the limited bearing seat 5. A plurality of second through holes 6 are evenly distributed in the annular groove 4.

[0029] The vibration module includes a connecting shaft 8 rotatably mounted on the base 1 , a U-shaped placement plate 14 fixedly mounted on the top of the connecting shaft 8 , a control slot 16 placed in the U-shaped placement plate 14 , a through shaft 17 and a motor 23 .

[0030] like Figure 5 As shown, a stepped cylindrical plug 9 is fixed on the connecting shaft 8, and the stepped cylindrical plug 9 includes a first plug 10 and a second plug 11 axially arranged from high to low, the size of the first plug 10 is larger than the size of the second plug 11, and the second plug 11 is embedded and inserted into the limiting bearing seat 5 of the first through hole 3, and the bottom end of the connecting shaft 8 is passed through and placed in the first through hole 3. A plurality of fourth through holes 12 are provided on the first plug 10. After the vibration module is installed on the rotating support, the second through hole 6 corresponds to the fourth through hole 12 one by one. The L-shaped limiting rod 13 is used to pass through the fourth through hole 12 and the second through hole 6 at different positions on the base 1, so as to limit the rotation angle of the support plate 27. When performing rotation limiting in this embodiment, only one L-shaped limiting rod 13 may be used to penetrate a fourth through hole 12 and the second through hole 6 corresponding to the fourth through hole 12; of course, multiple L-shaped limiting rods 13 may also be used to penetrate each fourth through hole 12 and the second through hole 6 corresponding to the fourth through hole 12 respectively, but the effect remains unchanged, and the rotation angle limiting of the support plate 27 and the clamping assembly can be achieved.

[0031] The U-shaped storage plate 14 has five through holes 15 at the same height on both sides. The two through shafts 17 are installed on both sides of the control groove 16, and the two through shafts 17 pass through the two fifth through holes 15. The two through shafts 17 are respectively sleeved with first damping springs 18 at positions between the control groove 16 and the fifth through holes 15.

[0032] The control slot 16 is a hollow rectangular structure with two ends open. A vibration block 19 is placed in the middle of the control slot 16. Two sixth through holes 20 are provided on the vibration block 19. Guide rods 21 are respectively placed through the two sixth through holes 20. The two ends of the two guide rods 21 are respectively fixed to the inner top and inner bottom of the control slot 16; the upper and lower parts of the guide rods 21 are respectively sleeved with second damping springs 22. When the motor 23 drives the disc 24 to rotate, thereby driving the vibration block 19 to move, the first damping spring 18 and the second damping spring 22 can play a buffering role and increase the service life of the device.

[0033] A strip-shaped hole 25 is formed at the top of the control groove 16 , and the top of the control groove 16 is fixedly connected to the bottom of the support plate 27 by a connecting rod 26 .

[0034] A disc 24 is rotatably mounted on one side of the vibration block 19. The output shaft of the motor 23 is connected to the eccentric point of the disc 24. The motor 23 is fixed to the U-shaped storage slot through a bracket 28. In this embodiment, the start and stop of the motor 23 can be controlled by adding a small controller, a power supply and a power button. Since this is a publicly available technology, no additional explanation is given.

[0035] The two limit plates include a first limit plate 29 and a second limit plate 30, and semicircular grooves 31 are respectively provided on the upper parts of the opposite sides of the first limit plate 29 and the second limit plate 30. The first limit plate 29 is fixed on the support plate 27, and the second limit plate 30 is slidably installed on the support plate 27. In this embodiment, a slide rail is provided on the support plate 27 to achieve the sliding installation of the second limit plate 30 on the support plate 27.

[0036] A seventh through hole 33 and an eighth through hole 34 are respectively provided at the same height on the first limiting plate 29 and the second limiting plate 30, and a threaded rod 32 is provided through the seventh through hole 33 and the eighth through hole 34. The contact position of the threaded rod 32 with the seventh through hole 33 is a fixed through connection, and the contact position of the threaded rod 32 with the eighth through hole 34 is a contact through connection; a nut 35 is movably installed at the end of the threaded rod 32, and the handle 36 is welded to the nut 35. Figure 6 It is a schematic side view of the handle 36.

[0037] A novel continuous casting roller bearing seat repairing method includes the novel continuous casting roller bearing seat repairing auxiliary device described above, and includes the following steps.

[0038] Step S1: Place the bottom of the continuous casting roller bearing seat upwards on the semicircular groove 31 of the first limit plate 29, turn the handle 36, and the nut 35 sleeved on the threaded rod 32 rotates and moves toward the first limit plate 29, thereby driving the second limit plate 30 to move toward the first limit plate 29 on the support plate 27, so that the semicircular groove 31 of the second limit plate 30 contacts and squeezes the continuous casting roller bearing seat, and the rotation of the handle 36 is stopped.

[0039] Step S2: Fully weld the bottom surface of the continuous casting roller bearing seat. First, weld the steps on the openings of each hole by hand, and then use two-way welding to repair the opposite side. Use low current surfacing and do not weld continuously to prevent serious deformation of other surrounding parts. Take protective measures to protect other parts that do not need repair welding to prevent welding slag from splashing, avoid clogging of water and oil circuits, and damage to thread teeth.

[0040] Step S3: Control the motor 23 to start, and the motor 23 starts to drive the disc 24 to rotate eccentrically, and the vibration block 19 connected to the disc 24 vibrates. The vibration of the vibration block 19 drives the connecting rod 26 connected to the top of the vibration block 19 to vibrate, and then the continuous casting roller bearing seat located on the support plate 27 vibrates, thereby performing aging vibration stress relief treatment on the continuous casting roller bearing seat.

[0041] Step S4: Based on the inner hole, re-process the bottom surface of the bearing seat to the drawing size and trim the surrounding weld nodules.

[0042] Step S5: trimming the water holes and oil holes on the bottom surface of the continuous casting roller bearing seat to ensure that the hole shape of the hole is beautiful, neat, consistent, and consistent in position, and there is no weld nodule on the hole wall. When repairing different positions of the continuous casting roller bearing seat during the trimming process, the L-shaped limit rod 13 is pulled out, the U-shaped placement plate 14 is rotated, and then the L-shaped limit rod 13 is used to penetrate the fourth through hole 12 and the second through hole 6 on the base 1 at the target position, and repair is performed again; Step S6: Turn the handle 36 to move the nut 35 away from the second limit plate 30, manually push the second limit plate 30 away from the first limit plate 29, take out the continuous casting roller bearing seat, and pressure test the continuous casting roller bearing seat. The pressure shall refer to the requirements of the drawing. The pressure shall be maintained for not less than 30 minutes and there shall be no leakage. After the pressure test is completed, blow the water holes clean and wipe the bottom surface.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
