Description
Technical Field
The utility model relates to a machining technology field, concretely relates to offset thin wall frame roof beam part stress deformation's device.
Background
The deformation is a physical phenomenon in the process of accompanying machining, and is mainly caused by uneven distribution of residual stress in the forming process of raw materials, uneven clamping stress in the machining process and release of machining stress. The ratio of the length, the width and the thickness of the aviation thin-wall frame beam is greatly different, and the appearance of the part in the thickness direction cannot meet the actual assembly and use requirements due to the fact that the part is extended in the width direction due to deformation.
At present, the deformation reducing method of the aviation thin-wall frame beam part is to repeatedly turn over two surfaces, roughly process the two surfaces to release deformation, repeatedly process two reference surfaces to remove deformation or correct the shape after the part is processed. The method wastes time and resources by repeatedly overturning, has the risk of shape correction damage, and has poor effect and difficulty in meeting the production requirement. Thereby restricting the lead time of the product and even the lead time of the whole machine.
The backing plate (or called as a tool including a vacuum clamp) is one of the devices conventionally adopted in the machining process of the aviation thin-wall frame beam, and only plays a role in clamping and positioning. The influence of deformation factors is not considered, high-efficiency machining of aviation thin-wall frame and beam products can be accurately and reliably realized according to theoretical geometric shapes, and the effect of offsetting or removing the deformation after machining cannot be realized. Even if the existing cushion plate has a structure with a curved surface or a broken line surface, the structure is only used for meeting the theoretical profile of a part, and the related dimension is convenient to control so as to meet the quality requirement.
