Clamping device for thin-wall parts

Abstract

The invention relates to a clamping device for solving the clamping of thin-wall parts, and provides a clamping device for thin-wall parts. The clamping device for thin-wall-parts structurally comprises a blind flange, sealing rings, a pressing ring, a space ring and chuck sleeve, wherein the blind flange is fixedly connected with the chuck sleeve; the pressing ring, one sealing ring, the space ring and the other sealing ring are arranged in a hole of the chuck sleeve in sequence from the inside out; and the pressing ring is located at one end of the blind flange. By utilizing the flexible deformation of the sealing rings, the outer circles of the thin-wall parts are clamped. Compared with the prior art, the clamping device for thin-wall parts has the advantages and beneficial effects of improving the circle center positioning precision of the thin-wall parts, evenly clamping the thin-wall parts and ensuring that the outer circles of the thin-wall parts are free of clamping mark and deformation. The clamping device is capable of solving the clamping of the outer circles of the thin-wall parts with the wall thickness of 1mm.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device for clamping thin-walled parts on aerospace testing equipment. Background technique [0002] In the field of aerospace, it is necessary to clamp thin-walled products. For example, the wall thickness of the missile body is only 1mm. In order to ensure that the thin-walled parts do not deform during the clamping process, the clamping is required to be firm and the product surface does not produce clamping. mark. The currently commonly used clamping tools are centering clamping mechanisms with uniform elastic deformation, including clamps such as collets, tympanic chucks, and butterfly reeds. However, these clamping devices have the disadvantage that a slightly fierce clamping force will cause deformation of the cartridge case and leave clamping marks. If the clamping force is slightly lighter, it cannot guarantee that the projectile will be hugged. If the fixture is install...
