A rigid support method for machining thin-walled cavity parts

Abstract

The invention discloses a rigid support method for processing a thin-walled cavity part, which comprises the following steps: Step 1: installing a flexible base layer A and a base layer B on each cavity and both ends of the thin-walled cavity part; 2: Apply curing agent on base layer A and base layer B respectively to form cured layer A and cured layer B; Step 3: Install several supporting tooling parts A and at least two supporting tooling parts B on the curing layer A respectively , Cured layer B, make cured layer A, cured layer B dry naturally under natural conditions. Under the action of several supporting tooling parts A and two supporting tooling parts B, the thin-walled cavity parts are rigidly supported, the phenomenon of vibration is solved, and the dimensional tolerance and shape tolerance of the processed thin-walled cavity parts are improved. Meet the requirements.

Description

technical field [0001] The invention belongs to the technical field of processing thin-walled cavity parts, and relates to a rigid support method for processing thin-walled cavity parts. Background technique [0002] In order to reduce the weight of the equipment, parts with large dimensions are usually designed as thin-walled cavity parts. For parts with dimensional tolerance and shape tolerance requirements on the outside of the cavity and the part, in the process of processing the outside of the part, due to the thin-walled cavity The thickness of the cavity part is small, and the outer wall of the thin-walled cavity part will vibrate, resulting in deformation of the part, resulting in the dimensional tolerance and shape tolerance of the processed thin-walled cavity part not meeting the requirements. [0003] To reduce the vibration of thin-walled cavity parts, it is necessary to support the inside of the cavity. If the tooling is directly used for support, there is also ...
