Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling fixture for processing aluminum alloy shell parts. Background Art

[0002] Aluminum circular thin-walled parts have the advantages of light weight, high specific strength and compact structure, and are often used in aerospace and other fields. Due to the poor rigidity of thin-walled structural parts, machining deformation is very easy to occur under the action of fixture clamping force and cutting load during the manufacturing process, making it difficult to control the machining accuracy and surface quality. Therefore, in actual production, general fixtures are often used to shape out-of-tolerance products, which is inefficient and easy to be pinched or even scrapped. The circular thin-walled aluminum products undertaken by the company are prone to deformation during the machining process, and the roundness requirements in the product process are strict. It is easy to be out of tolerance and even scrapped. In actual production, general fixtures are often used to shape out-of-tolerance products, which is inefficient and easy to pinch the products. In the absence of a base, the self-measurement of roundness is inaccurate and inefficient. In order to improve the production efficiency of subsequent fine machining, it is necessary to design a tooling that can solve this type of problem. Utility Model Content
