Abstract

The invention discloses a clamping device for clamping the cylindrical member, comprising: a frame for clamping both ends of the cylindrical member so as to fix the cylindrical member on the frame. an inner space; a circumferential fixing mechanism fixedly connected to the frame, the circumferential fixing mechanism including an embracing ring sleeved on the outside of the cylindrical member and fixed on the cylindrical member. The clamping device of the present invention can support and fix the cylindrical member from the outside of the cylindrical member, and does not need to set any clamping tool inside the cylindrical member, and can effectively control the force deformation of the cylindrical member during the welding process. , so that the welded cylindrical components meet the requirements of external dimensions.

Description

technical field [0001] The invention belongs to the technical field of metal material welding, and in particular relates to a clamping device. Background technique [0002] Aluminum alloy has the characteristics of good corrosion resistance, high specific strength and thermal conductivity, and can maintain good mechanical properties at low temperatures. It is widely used in aerospace, rail transportation, weaponry and other fields. In the field of aerospace, the integration and lightweight of aluminum alloy closed special-shaped aerodynamic component products are getting higher and higher, and the requirements for manufacturing precision are getting higher and higher. Before the closed pneumatic components are formed, the aluminum alloy cabin to be formed must be welded and packaged by metal welding technology. The influence of welding on the external dimensions of the cabin has been paid more and more attention. In order to ensure better use accuracy and orbit control cap...
