[0002] The shaft is a cylindrical object that passes through the middle of a bearing, a wheel, or a gear. It is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a metal round rod. As time goes by, the surface of the shaft will wear out, affecting its use. At this time, the shaft needs to be disassembled and repaired by applying repair materials.

[0003] At present, when repairing a shaft, it is necessary to fix the worn shaft. Due to the different sizes of the shafts, the existing tooling equipment cannot adjust and fix them well, and cannot effectively and firmly fix the shaft, which in turn affects the quality of the repair.

[0031] The shaft is one of the commonly used rotating connection parts in mechanical elements. It is generally in the shape of a round rod and made of solid and reliable material. However, as the shaft is used over time, it will cause long-term friction with other mechanical parts, which will cause the shaft to wear and damage. At this time, the shaft will not work normally and needs to be disassembled and repaired by applying repair materials.

[0032] In the related art, the online repair auxiliary tooling for shaft wear cannot perform good and firm fixation on shafts of different sizes when in use, and cannot perform rotation repair on the fixed shaft, which affects the repair quality and efficiency.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an auxiliary tool for online repair of shaft wear. When it is needed, the worn shaft is first placed on the placement plate 130, and the worn shaft on the placement plate 130 is moved to the middle of the two fixed plates 250 by the telescopic cylinder 120. The two threaded rods 240 are rotated and moved under the action of the threaded hole 230, and then the two fixed plates 250 are driven to move, so that the worn shaft can be clamped and fixed by the two fixed plates 250. At this time, the placement plate 130 is dropped by the telescopic cylinder 120 to repair the worn shaft. When the worn shaft needs to be rotated, the threaded rod 280 can be rotated to disengage the threaded hole 260, so that the limit block 220 can be rotated, driving the threaded rod 240 and the fixed plate 250 to rotate, and then driving the worn shaft fixed by the fixed plate 250 to rotate. In this way, the worn shafts of different sizes can be fixed well, and they can be rotated after being fixed, thereby improving the repair quality and efficiency of the repair.

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figure 1-Figure 4 The embodiment of the present application provides an auxiliary tool for online repair of shaft wear, including: a telescopic cylinder 120 arranged on the top of a base 110; a placement plate 130 arranged on the telescopic end of the telescopic cylinder 120; a bracket 140 arranged on the top of the base 110; a fixing mechanism 200 arranged on the bracket 140, and the fixing mechanism 200 includes: a limiting groove 210 opened on the side wall of the bracket 140; a limiting block 220 rotatably connected to the limiting groove 210; a threaded hole 230 opened on the side wall of the limiting block 220; a threaded rod 240 threadedly connected to the threaded hole 230, and a fixing plate 250 is arranged at one end of the threaded rod 240.

The placement plate 130 is welded and fixed to the telescopic end of the telescopic cylinder 120. There are two brackets 140, which are symmetrically arranged on the base 110. The brackets 140 are welded and fixed to the base 110. The fixing plate 250 is welded and fixed to the threaded rod 240. There are also two fixing mechanisms 200 that are symmetrically arranged.

[0037] When in use, first place the worn shaft on the placement plate 130, and move the worn shaft on the placement plate 130 to the center of the two fixed plates 250 by telescopic movement of the telescopic cylinder 120, and rotate the two threaded rods 240 so that the threaded holes 230 rotate and move, thereby driving the two fixed plates 250 to move and clamp the worn shaft. In this way, shafts of different sizes can be well and firmly fixed to ensure the quality of their repair.

[0038] In some embodiments, the fixing mechanism 200 also includes: a second threaded hole 260 , which is opened on the side wall of the limit block 220 ; a third threaded hole 270 , which is opened on the side wall of the bracket 140 ; ​​and a second threaded rod 280 , which is threadedly connected to the second threaded hole 260 and the third threaded hole 270 .

[0039] When in use, the limit block 220 can be rotated by rotating the threaded rod 2 to disengage it from the restriction of the threaded hole 260. When the limit block 220 rotates in the limit groove 210, the threaded rod 1 240 and the fixing plate 250 can be driven to rotate, and then the clamped and fixed worn shaft can be rotated. The shaft can be rotated according to the repair requirements to improve its repair efficiency.

[0040] In some embodiments, a cushion is provided on a side wall of the fixing plate 250 away from the threaded rod 240 .

[0041] Specifically, the soft pad and the fixing plate 250 are fixed by gluing.

[0042] When in use, the soft pad can better fix and protect the shaft.

[0043] In some embodiments, a handle is disposed on one end of the threaded rod 240 away from the fixing plate 250 .

[0044] Specifically, the threaded rod 240 is fixed to the handle by welding.

[0045] When in use, the turning handle can better facilitate the rotation of the threaded rod 240.

[0046] In some embodiments, a tool box is disposed on the side wall of the bracket 140 .

[0047] When in use, the tool box allows operators to store repair materials, brushes and other tools.

[0048] In some embodiments, the top of the placement plate 130 is configured in an annular structure.

[0049] When in use, the annular structure can ensure the stability of the shaft placed on the placement plate 130 and avoid shaking.

[0050] In some embodiments, the limiting groove 210 is configured in a circular groove structure.

[0051] When in use, the circular groove can achieve better rotation stability and also facilitate the rotation of the limit block 220.

[0052] In some embodiments, a rotating handle is provided on one end of the threaded rod 280 away from the threaded hole 3 270 .

[0053] Specifically, the rotating handle is fixed to the threaded rod 280 by welding.
