Description

Field of the invention

The present invention relates to the technical field of shaft alignment, and more particularly to a hydraulic alignment platform for shaft parts and a detection method therefor.

State of the art

The heat treatment refers to the technique of metal heat treatment in which the material surface or the internal chemical composition or organization of a solid state metal material to achieve the desired properties by heating, insulation and cooling is changed. Shaft parts, in particular the key components, must be subjected to a heat treatment. In the case of the shaft parts subjected to a heat treatment, deformations often occur due to uneven heating, as a result of which the requirements imposed on the cylindrical degree of the shaft parts can not be met.

When deformations are caused by the heat treatment, alignment techniques such as flame straightening and hydraulic straightening are often used. The effect achieved by Flammrichten at the shaft parts is not strong. Therefore, in actual use, a press is often used to align the shaft parts. However, in existing alignment processes, the press is often used so that repeated measurements and alignments must be made after alignment by compression, which must be raised several times in between by means of a hoisting crane. These repeated operations lead to a deterioration of the processing efficiency of the shaft parts and a waste of manpower.

Therefore, the invention of a hydraulic alignment platform for shaft parts and a detection method thereof is very important.

Object of the invention

To solve the above-mentioned technical problems, the present invention provides a hydraulic aligning platform for shaft parts and a detection method therefor.
