[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, reference Figure 1-5, which is the first embodiment of the present invention, provides a guide bearing auxiliary grinding device for supporting the guide bearing 800 to be ground on the shaft collar 900, including:

[0034] The support member 100 includes a connecting portion 101 adapted to the oil through hole 901 on the shaft collar 900, one end of the connecting portion 101 is a threaded end, the other end of the connecting portion 101 is provided with a supporting portion 102, the supporting portion 102 is provided with a supporting portion 103, and the connecting portion 101 and the supporting portion 103 are respectively located on both sides of the supporting portion 102;

[0035] The nut 200 is threadedly connected to the threaded end of the connecting portion 101 .

[0036] The support member 100 is installed at the oil hole 901 of the shaft collar 900. When the guide bearing 800 is ground on the shaft collar 900, the guide bearing 800 is supported. The operator no longer needs to drag the guide bearing 800, but only needs to hold the two sides of the guide bearing 800. Specifically, the connecting part 101 is inserted into the oil hole 901 of the shaft collar 900 and fastened by the nut 200. After fastening, the nut 200 and the abutment part 102 respectively abut against the inner and outer sides of the shaft collar 900, and then the guide bearing 800 is placed on the support part 103, and the inner bearing surface of the guide bearing 800 is abutted against the shaft collar 900. The two sides of the guide bearing 800 are held by hand to move the guide bearing 800 back and forth laterally, so that the inner bearing surface of the guide bearing 800 and the shaft collar 900 are ground against each other, thereby achieving the grinding of the inner bearing surface of the guide bearing 800 to meet the requirement of 80% contact between the guide bearing 800 and the shaft collar 900.

[0037] Of course, in order to reduce the shaking of the entire device during the grinding process, the outer diameter of the connecting portion 101 is the same as the aperture of the oil hole 901 of the shaft collar 900.

[0038] Furthermore, the abutting portion 102 is in the shape of a circular plate, the outer diameter of the abutting portion 102 is larger than the diameter of the oil hole 901 on the shaft collar 900 , and the connecting portion 101 and the supporting portion 103 are both in the shape of round rods integrally connected to the abutting portion 102 .

[0039] The support member 100 is in the shape of a short shaft as a whole, the abutting portion 102 is equivalent to the shoulder of the short shaft, the connecting portion 101 and the supporting portion 103 are integrally arranged on both sides of the shoulder, and the supporting portion 103 has a relatively larger outer diameter than the connecting portion 101 .

[0040] Example 2, reference Figure 1-5 , which is the second embodiment of the present invention, is different from the previous embodiment in that it further includes a sleeve 300 coaxially rotatably sleeved on the outside of the support portion 103, and the sleeve 300 is a cylindrical tube.

[0041] By setting the sleeve 300, during the grinding process of the guide bearing 800, the lower end of the guide bearing 800 is optimized from sliding contact with the support part 103 to rolling contact with the roller, which on one hand reduces the wear between the lower end of the guide bearing 800 and the device, and on the other hand makes it easier for the operator to move the guide bearing 800 laterally during the grinding process, further reduces labor intensity, and at the same time reduces friction noise.

[0042] Furthermore, it also includes an end cover 400 disposed on the support portion 103 , and the end cover 400 is located on a side of the sleeve 300 away from the abutting portion 102 .

[0043] The end cover 400 is provided to seal the sleeve 300 on the support portion 103 to prevent the sleeve 300 from being separated from the end of the support portion 103 .

[0044] Furthermore, the end cover 400 is in the shape of a circular plate, and a through hole 401 adapted to fit the support portion 103 is provided on the end cover 400 .

[0045] The outer end of the support portion 103 is reserved for mounting the end cover 400 . The end cover 400 is provided with a through hole 401 . The aperture of the through hole 401 is consistent with the aperture of the reserved portion. During installation, the reserved portion is inserted into the through hole 401 of the end cover 400 .

[0046] Furthermore, the outer diameter of the end cover 400 is greater than the outer diameter of the sleeve 300 .

[0047] On one hand, the end cover 400 is used to limit the roller, and on the other hand, the outer diameter of the end cover 400 is larger than the roller, which acts as a barrier during the grinding process to prevent the guide bearing 800 from moving to the outer end of the roller and falling from there, thereby improving safety in use.

[0048] Furthermore, the through hole 401 is a threaded hole, and the end cover 400 is fixed on the support portion 103 by threaded connection.

[0049] Furthermore, the end cover 400 is fixed on the support portion 103 by welding.

[0050] The end cover 400 can be fixed on the support portion 103 by threaded connection or welding, preferably by welding.

[0051] Furthermore, it also includes a gasket 500 sleeved on the connecting portion 101 , and one side of the gasket 500 is in contact with the abutting portion 102 .

[0052] Example 3, reference Figure 1-5 , which is the third embodiment of the present invention, is different from the previous embodiment in that the method for grinding the guide bearing 800 using the above guide bearing auxiliary grinding device includes the following steps:

[0053] Equipment assembly,

[0054] Put the gasket 500 on the connecting part 101 and push it until the abutting part 102 is on the side, then pass the connecting part 101 through the oil hole 901 of the shaft collar 900 that contacts the guide bearing 800 to be ground, and finally tighten the nut 200 on the threaded end of the connecting part 101 to complete the assembly;

[0055] Grinding,

[0056] Place the guide bearing bush 800 on the upper part of the sleeve 300, and make the inner bearing surface of the guide bearing bush 800 close to the shaft collar 900. Hold the two sides of the guide bearing bush 800 with both hands to move the guide bearing bush 800 back and forth horizontally on the drum. During the process of the guide bearing bush 800 moving back and forth horizontally, the inner bearing surface of the guide bearing bush 800 is ground.

[0057] After the equipment is disassembled and the grinding is completed, the guide bearing 800 is removed, the nut 200 is unscrewed, and the connecting part 101 is taken out from the oil hole 901 of the shaft collar 900.

[0058] When the operator moves the guide bearing 800 laterally for grinding, a thrust is applied to the guide bearing 800 toward the shaft collar 900 to ensure the grinding effect between the guide bearing 800 and the shaft collar 900 .

[0059] Since the entire device is supported on the lower part of the guide bearing 800 during the grinding process, the operator is no longer required to drag the guide bearing 800, which reduces the labor intensity during the grinding process and makes the task of grinding the guide bearing 800 convenient and easy. At the same time, compared with manually dragging the guide bearing 800, the device can keep the guide bearing 800 in horizontal motion during the grinding process, so that the quality and effect of grinding are effectively improved.
