Problems solved by technology
[0002] Welding is a common processing method, which can assemble multiple independent parts into one body. However, various problems are often encountered in the specific welding process. For example, as shell parts, their manufacturing accuracy is relatively low. Low, when assembling and welding with other parts, how to ensure the size after welding has become a difficult problem, especially for conical shells, the angle of the cone often has a dimensional deviation of 1 to 2° due to manufacturing errors. If the tapered surface is directly used as a positioning element, the positioning error will be relatively large, and the size of the welded part cannot be well guaranteed.

Embodiment Construction
[0042] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.
[0043] As indicated in this application and claims, the terms "a", "an", "an" and / or "the" do not refer to the singular and include the plural unless the context clearly indicates an exception.
[0044]In some embodiments, a clamping and positioning device for welding processing is used for figure 1 and figure 2 The shown conical shell assembly M is welded, and the conical shell assembly M is mostly used on aircraft or ships, and is often buckled on some parts for dustproof or isolation. The conical shell assembly M includes a conical shell M1 and ribs M2. The ribs M2 are arranged in an annular array and inserted into the outer tapered surface of the conical shell M1. The welding difficulty of the conic...

The invention discloses a clamping positioning device for welding processing. The clamping positioning device comprises a base body, a compression screw, a positioning mandrel assembly and a pressingrod; the base body is provided with a first vertical plate, a second vertical plate and a cantilever beam which are arranged oppositely, and the positioning mandrel assembly, the pressing rod and thecompression screw are respectively inserted into the first vertical plate, the second vertical plate and the cantilever beam; the pressing rod approaches the positioning mandrel assembly through the spiral motion to fix a conical shell; a rib plate is inserted into a rib plate slot in the cantilever beam and fixed by screwing in the compression screw, and welding can be carried out after the rib plate and the rib plate slot are fixed. The positioning mandrel assembly specifically comprises a stress application mandrel rod, a positioning mandrel sleeve and a positioning block assembly, whereinthe stress application mandrel rod is inserted into the positioning mandrel sleeve and moves along the axial direction of the positioning mandrel sleeve, so that the positioning block assembly is gradually expanded to form an internal support type fixation to a shell assembly. At the same time, the positioning block assembly can adapt to the change of an included angle between inner conical surfaces of the conical shell and change the own angle through the structural design of a positioning slot block and a positioning inserting block that are hinged to each other, and always maintain the fitwith the built-in surface of the conical shell to ensure the welding quality.
