Description

Axis Correcting Device {Correcting Device of Shaft}

The present invention is a device capable of correcting bending defects of a rotating shaft, and measuring the bending degree of the rotating shaft by a dial gauge, and using the hydraulic equipment, the above-mentioned rotating shaft can be calibrated within mechanical tolerances. Device.

In general, the shaft diameter of the rotating body used in various industrial facilities is produced in various ways according to the equipment, it is difficult to perform the axis correction work, and to correct the bending defect, one of the major defects generated in the shaft within the specified value There is no device that can be developed.

In addition, the existing shaft calibration device operates the locating cylinder according to the deformation position of the material to move the material and adjust its horizontal position or move the support frame from the base to adjust the position of the material. There is a difficulty.

On the other hand, the conventional shaft correction apparatus has a drawback that the installation and operation method of a complicated structure is not simple, and the cost for repair is very high.

Failure to calibrate the rotating body due to bending can result in prolonged maintenance time and additional material costs incurred by machining the new rotating shaft and, in critical installations, significant production losses due to production interruptions.

The present invention was devised to solve the problems as described above, and the object of the present invention is to standardize the diameter of the rotating shaft shaft used in various industrial facilities, and to manufacture a shaft calibration device equipped with a gauge that can measure the bending state By improving the quality of maintenance by scientifically calibrating the rotating shaft that is caused by bending defects, it is to reduce the required cost for all matters, such as extending the life of the device, reducing the cost of reuse, increase productivity.

According to FIG. 1, a lubricating movement in the horizontal direction on the axial straightener frame 1, the sliding bed 2 extending perpendicular to the above-mentioned frame between the above-mentioned frame 1, and the aforementioned sliding bed 2. And a shaft clamp (5) installed perpendicular to the sliding bed described above, a shaft bushing (4) formed in the aforementioned shaft clamp to fix the shaft, and mounted on the sliding bed (2) described above, and calibrated. Hydraulic jack 14 for calibrating the target axis, the hydraulic jack 14 to support the above-mentioned hydraulic jack 14 from the bottom, and is fixed on the sliding bed 2 described above, and the sliding bed 2 described above It is configured to include a shaft bed support (9) for supporting the above-mentioned sliding bed (2) at the bottom of the), to adjust the height of the above-mentioned sliding bed.

Figure 2 is an exemplary view showing a method of mounting and calibrating the rotating shaft according to the present invention.

According to Figure 2, after the installation of the shaft clamp 5 and the shaft bushing (4), which is a fixing device suitable for the diameter of the rotating shaft, using the clamp bolt (7) to fix the shaft necessary for calibration.

After the shaft fixing operation is completed, the hydraulic jack base 8 and the hydraulic jack base support 10 are moved to the rotating shaft bending correction portion, and then the hydraulic jack 14 is placed on the hydraulic jack base 8 described above. After applying hydraulic pressure to the hydraulic jack cylinder 11 to confirm the amount of change of the dial gauge 12, the torque of the hydraulic jack cylinder 11 is adjusted.

Therefore, by the hydraulic jack, the calibration portion of the shaft can be calibrated within the range indicated by the gauge.
