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 and positioning device for welding processing. Includes base body, compression screw, locating mandrel assembly and compression rod. The base body is provided with the first vertical plate, the second vertical plate and the suspension beam which are arranged oppositely, on which the positioning mandrel assembly, the pressure rod and the compression screw are inserted respectively, and the pressure rod approaches the positioning mandrel assembly through a spiral movement to fix the cone. Shaped shell, the rib plate is inserted in the rib plate slot on the cantilever beam, and fixed by screwing in the compression screw. After the two are fixed, they can be welded. The positioning mandrel assembly specifically includes a force mandrel rod, a positioning mandrel sleeve and a positioning block assembly. The force mandrel rod is inserted into the positioning mandrel sleeve and moved along its axial direction, so that the positioning block assembly is gradually stretched to form a The shell assembly is internally braced and fixed. At the same time, the positioning block assembly can adapt to the change of the included angle of the cone surface in the conical shell through the structural design of the positioning slot block and the positioning insert block that are hinged to each other. .

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a clamping and positioning device for welding processing. Background technique [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 1-2° 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. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the invention di...
