Problems solved by technology

According to the existing processing method, the processing part is measured during processing, compared with the design size required by the drawing, and the processing allowance is judged and repeatedly corrected based on the experience of the workers. The labor intensity is high and the processing efficiency is low. The temperature difference between the coordinate measurement room and the assembly environment leads to the out-of-tolerance of the three-coordinate measurement of the qualified parts processed on

Example Embodiment

[0024] The present invention will be described in further detail below.

[0025] Aiming at the problem of high-precision and easy-to-deformable deformation of helicopter aluminum alloy discs and rings, the comparative processing method for aluminum alloy discs and rings of the present invention is to clamp the comparison reference part with the processing compensation value in the free state and compare the reference part and The error compensation value between the assembly standard parts is processed to compensate, so as to ensure the high precision of the processing, and effectively solve the technical problem of the difficult processing of the helicopter aluminum alloy high-precision and easily deformable disk ring moving parts. The specific steps are as follows:

[0026] Step 1. Compare the processing of reference parts:

[0027] Under any normal ambient temperature, process a comparison reference part for comparison measurement and processing according to the conventional proce...

Abstract

The invention belongs to the technical field of numerical control machining, and relates to a comparison machining method for aluminum alloy discs and rings. The method includes the steps: machining a comparison reference part for comparison measuring and machining at an optional ambient temperature; measuring and recording a deviation compensation value A of the size of the comparison reference part in a clamped machining state and in a loosened free state; measuring the comparison reference part after keeping the comparison reference part at a constant temperature, and calculating a deviation compensation value B of the comparison reference part and a standard assembly part according to measuring results; and during practical machining, placing the comparison reference part on a machining site, and performing compensation machining for parts to be machined according to the deviation compensation value A and the deviation compensation value B. By the aid of the comparison machining method, the problem of machining deformation of easily deforming movable parts like aluminum alloy discs and rings of helicopters can be solved, dimensional precision and uniformity are ensured, the requirement of assembly coordination is met, and high numerical control machining efficiency can be obtained.

Description

technical field [0001] The invention belongs to the technical field of numerical control processing, and relates to a comparative processing method for aluminum alloy disk ring parts. Background technique [0002] At present, there are some aluminum alloy high-precision and easy-to-deform disk ring parts in the moving parts of the helicopter. During CNC machining, it is affected by the ambient temperature of the workshop, the temperature of the machine tool guide rail, and the temperature of the cooling system. The temperature difference in the processing area of ​​the workshop in different seasons exceeds 10 degrees. There are also several degrees of temperature change, and the deformation of parts due to temperature changes during processing is obvious. According to the existing processing method, the processing part is measured during processing, compared with the design size required by the drawing, and the processing allowance is judged and repeatedly corrected based on...
