Embodiment 1

[0023] The processing method of the upper half frame of a certain type of helicopter fuselage, the processing steps are:

[0024]1. Manufacture the blank of the upper half frame of the fuselage: use sheet blanking to form a rectangular wool, process the left positioning hole 3 and the right positioning hole 4 at both ends of the wool length direction, establish a three-dimensional coordinate system, and use the right positioning hole 4 The center point is the origin, the straight line passing through the center points of the left positioning hole 3 and the right positioning hole 4 is the X axis, the positive direction is toward the left positioning hole 3, the positive direction of the Y axis is backward, and the positive direction of the Z axis is upward; The outline of the side 8 of the blank is processed from the top view of the upper half frame, and the outline of the side 8 of the blank is extended by 70mm according to the theoretical outline of the upper half frame of the...

Abstract

The invention belongs to the technology of machining and relates to a modified method for processing a half frame on the upper portion of a helicopter body and a vacuum sucking clamp. The method for processing the half frame on the upper portion of the helicopter body includes steps of manufacturing a blank of the half frame of the upper portion of the helicopter body; processing the lower surface (5) of the half frame of the upper portion of the helicopter body; processing the upper surface (2) of the half frame of the upper portion of the helicopter body; processing the lateral side (1) of the half frame of the upper portion of the helicopter body. The vacuum sucking clamp is characterized by comprising a clamp body (9), a left positioning pin (12), a right positioning pin (13) and a pressing bolt, wherein the clamp body (9) is provided with a vacuum sucking mechanism inside. The method for processing the half frame on the upper portion of the helicopter body solves the problems that part deformation is high, profile tolerance, thickness and size of webs are difficult to guarantee during processing, and processing yield and processing efficiency are improved.

Description

technical field [0001] The invention belongs to mechanical processing technology, and relates to the improvement of the processing method of the upper half frame of the helicopter fuselage and a vacuum adsorption fixture. Background technique [0002] For the structure of the upper half frame of a fuselage of a certain type of helicopter, see figure 1 and figure 2 , the outline shape of the upper half frame of the fuselage is bow-shaped, the side 1 of the upper half frame of the fuselage is a plane and a curved surface connected to form a complex surface, and the upper surface 2 of the upper half frame of the fuselage is provided with horizontal and vertical reinforcing ribs frame, the bottom surface of the frame is a web, and there are left positioning holes 3 and right positioning holes 4 on the upper surface 2 of the upper half frame of the fuselage, as well as other boss structures and through hole structures, the upper half of the fuselage The lower surface 5 of the ...
