Embodiment Construction

[0052] The present invention will be described in detail below with reference to the accompanying drawings.

[0053]The present invention creates a specific processing method and comprises the following steps:

[0054] (1) The bar is drilled before boring, then solid solution treated, and then turned and bored on a CNC lathe to form such image 3 The blank shape shown ( image 3 The auxiliary process hole 207 in the process is processed in the next step), that is, the blank is a body of revolution with a groove structure, and the groove structure and the final product have the following structural correspondence and have a machining allowance:

[0055] The outer end surface 201 of the groove structure corresponds to the large end surface 105 of the final product,

[0056] The inner end face 202 of the groove structure corresponds to the small end face 110 of the final product,

[0057] The groove bottom surface 203 of the groove structure corresponds to the inner end surfac...

Abstract

The invention provides a method for machining a flange plate for a helicopter control system. The method comprises the following steps that two auxiliary process holes are symmetrically formed in the bottom of a blank which is a rotary body with a groove-shaped structure by taking the middle shaft of the blank as the center, and auxiliary positioning is carried out through the auxiliary process holes in the follow-up machining process. According to the method, the precision grade of the product and the qualified rate of the product can be improved, and the problems that products machined through a conventional process are low in precision, high in machining difficulty, low is qualified rate and the like are solved.

Description

technical field [0001] The invention relates to the field of bearing structure design, in particular to a method for processing a flange used in a helicopter control system. Background technique [0002] The flange used in the helicopter control system is of great significance to the stable operation and smooth operation of the helicopter, and is one of the important structural components of the helicopter operating system. The flange has such figure 1 The structure shown: includes a central ring body 101 and a pair of flanges 102 symmetrically arranged at both ends of the central ring body 101; The outside of the body 101 is a small outer circle 104; the flange 102 has an end face that is flush with one end of the ring body of the central ring body 101, and the end face that is flush with the two is called a large end face 105; the flange 102 The other end face (inner end face 109) and the ring body other end (small end face 110) of the central ring body 101 are stepped s...
