[0032] Please see attached Figure 1-4 In one embodiment of the utility model, a grinding drive disk for a leveling roller 40 is provided, comprising a fixed disk 10 and a support sleeve 20. First of all, it should be noted that, considering that the leveling roller 40 in the prior art is a relatively special roller, and is limited by the rolling mill arch, its roller flat head is designed to be very short. When the center frame and the head frame faceplate 30 are moved to the limit during grinding, the faceplate still cannot contact the flat head of the roller, that is, it cannot be driven to rotate. The present application solves the above-mentioned defects in the prior art by providing a leveling roller 40 grinding drive disk. The details are as follows:

[0033] The fixed plate 10 is used to be fixedly connected to the head frame disc 30; the support sleeve 20 includes an extension end 210 and a driving end 220 that are relatively arranged, and the extension end 210 is connected to the side of the fixed plate 10 away from the head frame disc 30, and a driving cavity 221 for installing the leveling roller 40 is formed in the driving end 220, and the driving cavity 221 is matched with the leveling roller 40.

[0034] Specifically, the grinding drive disk of the smoothing roller 40 in the present application includes a fixed disk 10 and a support sleeve 20. The fixed disk 10 is used to be fixedly connected to the headstock faceplate 30 of the grinder, thereby replacing the flat head of the smoothing roller 40 to be directly fixedly connected to the headstock faceplate 30; and the support sleeve 20 is used to connect the fixed disk 10 and the smoothing roller 40, thereby supplementing the length difference of the smoothing roller 40 to ensure that the smoothing roller 40 can also contact the headstock faceplate 30 for grinding, that is, through the entire grinding drive disk as an intermediate machined workpiece.

[0035] The support sleeve 20 includes an extension end 210 and a drive end 220. The extension end 210 can be set according to the missing length between the smoothing roller 40 and the grinder headstock faceplate 30 to ensure that the smoothing roller 40 can be connected to the support sleeve 20 through the fixed disk 10 and the headstock faceplate 30. The extension end 210 is connected to the support sleeve 20 on the side of the fixed disk 10 away from the headstock faceplate 30 to be set between the fixed disk 10 and the smoothing roller 40; and the drive end 220 is used to connect the smoothing roller 40. When connected, it can be connected to the headstock faceplate 30 through the fixed disk 10. The disk 30 drives the entire grinding drive disk to rotate, and the leveling roller 40 connected to the driving end 220 also rotates together for grinding, so a driving cavity 221 is formed in the driving end 220, and the driving cavity 221 is used for the connection and installation of the leveling roller 40, so that the flat head end of the leveling roller 40 is clamped in the driving cavity 221, and to ensure a stable connection, the driving cavity 221 needs to be matched with the leveling roller 40. The matching setting here means that the size and shape of the driving cavity 221 are consistent with the leveling roller 40.

[0036] It is worth mentioning that the grinding drive disc of the present application can be cast from 4A01 aluminum alloy, which has the characteristics of light weight and high strength, and is convenient for twisting when grinding the smoothing roller 40.

[0037] As a preferred embodiment of the present invention, the fixing plate 10 extends radially outward to form a flange 110 arranged around the fixing plate 10 , and the flange 110 is arranged on a side away from the head frame faceplate 30 .

[0038] It should be noted that the flange 110 is arranged around the fixed plate 10 to form an installation reference space 111 together with the edge of the fixed plate 10. When connecting the fixed plate 10, the installation reference space 111 can be aligned with the head frame faceplate 30, so that the head frame faceplate 30 can be fitted in the installation reference space 111, which is convenient for subsequent connection and fixation of the fixed plate 10.

[0039] Preferably, a plurality of mounting holes 112 are provided on the flange 110, and the mounting holes 112 are used to connect the flange 110 and the head frame faceplate 30 as a whole by bolts after the position is installed, calibrated and fitted, so that the entire grinding drive disk and the head frame faceplate 30 are connected as one; it is worth mentioning that during installation, a gap of 0.1 mm to 0.3 mm can be reserved between the mounting reference space 111 and the head frame faceplate 30 to avoid deformation caused by frequent twisting.

[0040] As a preferred embodiment of the utility model, the fixed disk 10 is recessed inward from the middle to form a cavity 120 extending into the support sleeve 20. The support sleeve 20 also has a through hole 230 extending axially. The through hole 230 is arranged between the cavity 120 and the driving cavity 221, and the two ends of the through hole 230 are respectively connected to the cavity 120 and the driving cavity 221.

[0041] It should be noted that the cavity 120 is used to reduce the weight of the entire grinding drive disk, thereby facilitating twisting, while the through hole 230 serves as an exhaust, which is arranged and connected between the cavity 120 and the drive cavity 221, thus forming a hollow mechanism to prevent the positioning surface between the through hole 230 and the drive cavity 221 for contacting the bottom of the smoothing roller 40 from breaking.

[0042] As a preferred embodiment of the present invention, a plurality of weight-reducing holes 130 are provided on the fixing plate 10 , and the plurality of weight-reducing holes 130 are arranged at intervals along the circumference of the fixing plate 10 .

[0043] It is worth noting that the weight-reducing holes 130 are used to reduce the weight of the fixed plate 10 , and a plurality of the weight-reducing holes 130 are arranged at intervals along the circumference of the fixed plate 10 to ensure uniform weight reduction while taking into account structural strength.

[0044] As a preferred embodiment of the present invention, one end of the cavity 120 close to the through hole 230 is bent toward the through hole 230 .

[0045] It is worth noting that since the cavity 120 mainly bears the axial thrust, in order to ensure that the structure will not be damaged when subjected to a large axial thrust, the end of the cavity 120 close to the through hole 230 is bent toward the through hole 230 to form an inner arc of the cavity 120.

[0046] Furthermore, an arc chamfer is provided at the connection between the extension end 210 and the fixing plate 10 .

[0047] It should be noted that the connection between the extension end 210 and the fixing plate 10 is mainly subjected to torque. Therefore, in order to prevent stress concentration, an arc chamfer is provided at the connection between the extension end 210 and the fixing plate 10 to form an outer arc of the support sleeve 20.

[0048] Furthermore, the driving cavity 221 is recessed into the supporting sleeve 20 to form a plurality of corner cleaning holes 222 , and the plurality of corner cleaning holes 222 are arranged at intervals along the circumference of the driving cavity 221 .

[0049] It should be noted that the corner cleaning hole 222 is used to prevent the flat head of the leveling roller 40 from being squeezed during installation, causing extrusion damage to the internal structure, and can also prevent small foreign objects from getting stuck, thereby facilitating the installation of the leveling roller 40 and machining.

[0050] Furthermore, the wall thickness distance between the outer wall of the support sleeve 20 and the cavity 120 is 30 mm to 32 mm.

[0051] It should be noted that the cavity 120 is provided to reduce the deadweight and facilitate torsion to prevent cracking, but the structural strength must also be ensured. The present application is a preferred embodiment. While reducing the weight and being able to withstand a large torque, the wall thickness distance from the outer wall of the support sleeve 20 to the cavity 120 can be set to 30 mm to 32 mm. Preferably, the wall thickness distance can be set to 30 mm, and those skilled in the art can set it according to actual conditions.

[0052] Furthermore, the depth of the driving cavity 221 is 50 mm to 60 mm.

[0053] It is understandable that the smaller the depth of the driving cavity 221, the less stable the installation of the smoothing roller 40 may be. The deeper it is, the easier it is to install the smoothing roller 40. Considering the length of the flat head end of the smoothing roller 40 and the connection stability, preferably, the depth of the driving cavity 221 can be set to 50mm~60mm, and technical personnel in this field can choose according to actual needs.

[0054] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
