Technical Field
[0001] The utility model relates to a fixing device for grinding and processing shaft workpieces, belonging to the technical field of mechanical processing equipment. Background Art
[0002] During the mechanical maintenance and assembly process, it is very common to grind, polish and process shaft workpieces. Since most shaft workpieces are heavy and long, they are prone to roundness loss during the grinding process, which reduces the accuracy of the shaft and even scraps the workpiece, causing unnecessary losses. In order to ensure the machining accuracy of the shaft, large machine tools and other facilities are often required, which will significantly increase the cost for some small companies or the maintenance of a single workpiece.

[0004] The technical solution of the utility model is:
[0005] A fixing device for grinding and processing shaft workpieces comprises a working platform, a hydraulic lifting mechanism, a walking track, a walking motor, a rotating motor, a supporting wheel and a walking wheel. Two supporting wheels matching the shaft workpiece are respectively arranged at both ends of the shaft workpiece. Each supporting wheel is driven by a rotating motor. Each rotating motor is respectively fixed to a walking motor. Each walking motor travels on the walking track via a walking wheel. The walking track is fixed on the working platform. A hydraulic lifting mechanism is arranged under the working platform. The overall arrangement is bilaterally symmetrical.
