Embodiment Construction

[0014] The installation and working methods of the present invention will be described below in conjunction with the accompanying drawings.

[0015] first step, such as figure 1 As shown, part 3 is a conical tubular structure, which needs to be turned and milled on its inner and outer surfaces, and clamped. The part 3 is fixed and clamped by the positioning fixture and the intermediate pressure plate 2, so as to ensure that the outer surface of the blank and the inner surface of the intermediate pressure plate 2 are more than 2 The area can be processed, except for the area of ​​the intermediate platen 2 and the installation position 1 of the positioning fixture for rough turning, leave a margin of 1mm;

[0016] The second step is to install the four side splints 4, remove the middle pressure plate 2, and fix the part 3 from the outside, such as figure 2 As shown, the remaining unprocessed area in the first step of rough turning, finishing turning and finishing milling inclu...

Abstract

The invention relates to a machining method for a helicopter fairing supporting piece. The method includes the steps that firstly, preprocessing is conducted; secondly, a positioning clamp is installed at the clamping installation location 1, areas except for a middle pressure plate 2 and the clamping installation location 1 are subjected to rough turning, and the allowance is 1mm; thirdly, the middle pressure plate 2 is removed, four lateral clamping plates 4 are installed, a part 3 is fixed from the outer side, and the residual unprocessed areas in the first step are subjected to rough turning, finish turning and finish milling; fourthly, the part and the positioning clamp are connected through cooperation of a sunken hole machined in the second step and a corresponding threaded hole in the positioning clamp, the lateral clamping plates 4 are removed, the residual area of secondary finish turning is subjected to finish turning, and the residual portions, except for a lightening hole, of the part 3 are machined; and fifthly, an outer end pressure plate 5 is installed at the outer end face of the part 3, and the lightening hole in the outer end pressure plate 5 is subjected to rough milling and finish milling. The clamping purpose is reasonably achieved in machining, resources of tools and numerically-controlled machine tools are saved, cycling time is greatly shortened, and a good effect is achieved.

Description

technical field [0001] The invention belongs to the field of mechanical processing and relates to a processing method for a helicopter fairing support. Background technique [0002] The fairing support is an important part of the lift system of the helicopter. The blank is a die forging and the part size is large (600mm in diameter and 230mm in thickness). In the past, it was processed by multiple machine tools. Due to the difficulty in clamping, the stability of the processing conditions was poor, so the processing efficiency It is not high, and takes up more machine tools and tooling resources. Contents of the invention [0003] The technical problem to be solved by the present invention is the problem caused by the difficulty in clamping during processing of traditional helicopter fairing support parts. [0004] Technical scheme of the present invention: a kind of processing method of helicopter fairing support part, comprises the following steps, [0005] The first s...
