Abstract

The invention belongs to the technical field of machining, and particularly relates to a thin-walled cylinder part assembling and welding supporting device. An existing part structure is utilized, thenovel thin-walled cylinder part assembling and welding supporting device is provided, quick supporting and heat radiation of thin-walled cylinder part assembling and welding are achieved, damage caused when a supporting device is removed is avoided, and the production cost and storage space are reduced. According to the thin-walled cylinder part assembling and welding supporting device, three sets of wedge-shaped movable cushion blocks precise in angle are designed, the stress deformation problem and the dabber retreating problem caused during demounting and mounting are solved, and high-precision welding of a thin-wall cylinder part is achieved. According to the thin-walled cylinder part assembling and welding supporting device, a conical positioning ring and the conical faces of the cushion blocks are combined to adjust the radial clearance, the machining errors of all workpieces are effectively complemented for, and the positioning precision is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a welding support device for thin-walled cylindrical parts. Background technique [0002] The combined welding of thin-walled cylindrical parts is the most difficult in the field of welding. The main reason is to consider the influence of welding deformation. A simple support device must be made during welding. This support device is affected by welding heat transfer and the structure of thin-walled cylindrical parts. It is difficult to disassemble the supporting device after welding, and it is often necessary to destroy the supporting device for removal. This method is time-consuming, labor-intensive, and wasteful, so designing a support device for assembly welding of thin-walled cylindrical parts by using the existing part structure to realize the rapid disassembly and reuse of the support device after assembly and welding of thin-walled cylindrical pa...
