Thin-wall cavity part machining rigid supporting method

Abstract

The invention discloses a thin-wall cavity part machining rigid supporting method. The thin-wall cavity part machining rigid supporting method comprises the following steps: (1) flexible basal body layers A and basal body layers B are mounted in each molding cavity and at the two ends of thin-wall cavity parts; (2) curing agents are coated on the basal body layers A and the basal body layers B toform curing layers A and curing layers B; and (3) multiple supporting tool pieces A and at least two supporting tool pieces B are correspondingly mounted on the curing layers A and the curing layers B, so that the curing layers A and the curing layers B are naturally dried under natural conditions. Under the effects of the multiple supporting tool pieces A and the two supporting tool pieces B, thethin-wall cavity parts are rigidly supported, so that the vibration phenomenon is solved, and the dimensional tolerance and the form and location tolerance of the machined thin-wall cavity parts meetthe 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.

Problems solved by technology

[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 an accuracy error in tooling processing, and it will not be able to support the cavity if it cannot be completely fitted. Therefore, At present, the commonly used method is to fill the cavity of thin-walled cavity parts with paraffin wax. Although this solution solves the vibration of thin-walled cavity parts during processing, paraffin cannot form a rigid support for the cavity of thin-walled cavity parts. Press and hold the thin-walled cavity parts, so that when the outer plane of the thin-walled cavity parts is processed, the thin-walled cavity parts can only be processed with a small amount of multiple feeds, resulting in low production efficiency and high production costs
