Problems solved by technology
It is well known that the longer the shafting, the less controllable its concentricity during machining
However, the shafting of large controllable pitch propellers is usually longer, and may exceed 15 meters, which will cause the coaxiality of the processed shafting to fail to meet the requirements

Embodiment Construction
[0042] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0043] The embodiment of the present invention provides a shaft processing method, which is suitable for hollow shafts, such as figure 1 As shown, the processing method includes:
[0044] Step 101: Set four measuring points on the outer wall of the shaft 100 to be processed, the four measuring points are arranged equidistantly around the axis of the inner hole of the shaft 100 to be processed, and the four measuring points are respectively the first measuring point A , the second measurement point B, the third measurement point C and the fourth measurement point D (see figure 2 ), wherein the first measurement point A and the third measurement point C are arranged symmetrically along the radial direction of the axis to be processed 1...

The invention discloses a shaft system processing method and tool, and belongs to the field of mechanical processing. The processing method comprises the steps of arranging four measuring points on the outer wall of a shaft to be processed, wherein the four measuring points are circumferentially arranged at equal intervals by treating a central axis of an inner hole of the shaft to be processed asa shaft; measuring the wall thickness of places provided with the four measuring points; calculating the coaxiality of the shaft to be processed based on the wall thickness of the places provided with the four measuring points; determining whether the coaxiality of the shaft to be processed is within an allowable deviation range; if not, calculating the first deviation value and the second deviation value based on the wall thickness of the places provided with the four measuring points; providing two correcting choke plugs; arranging eccentric propping pin holes in the correcting chock plugsby treating the centers of the correcting choke plugs as the reference and on the basis of the first deviation value and the second deviation value, wherein the two correcting choke plugs are coaxially fixed to two ends of the inner hole in the shaft to be processed; fixing propping pins of a lathe to the two eccentric propping pin holes; and processing the outer wall of the shaft to be processedthrough the lathe. With the adoption of the method, the coaxiality of a shaft system can be effectively ensured.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a shaft processing method. Background technique [0002] The shaft system in the controllable pitch propeller is an important part of the controllable pitch propeller, which can play the role of accommodating the oil pipe. [0003] The shaft system is usually a hollow shaft (that is, there is a through hole along the central axis). In order to ensure that the oil pipe installed in the inner hole does not get stuck, it is necessary to have a certain degree of coaxiality between the inner hole and the outer circle of the shaft system. high demands. It is well known that the longer the shafting, the more uncontrollable its concentricity during machining. However, the shafting of large controllable pitch propellers is usually longer, and may exceed 15 meters, which will cause the coaxiality of the processed shafting to fail to meet the requirements.
