Embodiment 1

[0037] Embodiment 1 of the processing method of the thin-walled half-shell parts of the present invention: as Figure 1 to Figure 17 shown, including the following steps,

[0038] Step 1, according to the position of the part blank 2 in the plate-shaped base material, the shape of the part blank 2 is roughly machined by a CNC milling machine, and a process handle 3 integrally connected around the part blank 2 is reserved on the plate-shaped base material. 3 is a U-shaped plate body surrounding the part blank, leaving no more than R4 rounded corners at all corners, and milling a pit at the connection between the process handle 3 and the part blank 2, and the pit surrounds the part blank 2; in the part The machining allowance is reserved on the blank 2, so that the convex surface of the blank 2 and the clamping platform are exposed from the upper surface of the process handle 3, and the mounting end surface of the clamping platform on the component blank 2 is raised from the upp...

Abstract

The invention discloses a machining method for a thin-wall semi-shell part. The machining method includes reserving a process handle around a part blank; performing finish machining on the outer convex surface and the inner concave surface of the part blank with the upper and lower plate surfaces of the process handle serving as positioning surfaces; opening a groove on the inner concave surface, wherein the shape of a contact of an electrical spark electrode for opening the groove is matched with that of the groove; and removing the process handle through a clamping platform which clamps the part blank tightly. During usage, clamping of the part blank is achieved indirectly through tightly clamping of the process handle, so that the part blank cannot be clamped directly in a machining process, effects of the clamping stress on the part blank are reduced, and the problem that thin-wall semi-shell parts cannot be clamped by common fixtures directly in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical parts processing, in particular to a method for processing thin-walled semi-shell parts. Background technique [0002] The thin-walled half-shell part 1 has an outer convex surface 11, an inner concave surface 12, and a concave inner cavity on one side of the inner concave surface 12. On the inner concave surface 12, there are several grooves 13 distributed side by side at intervals. There are several clamping platforms 14 distributed at intervals around the opening of the inner cavity. The clamping platforms 14 have installation end surfaces 15 that are aligned with the convex surface, and the installation end surfaces 15 of all the clamping platforms 14 are on the same plane. When processing thin-walled shell parts, conventional mechanical processing methods are generally used to finish the parts. However, due to the structural characteristics and material properties of the parts, commonly us...
