Multi-angle adjusting and clamping device for welding of special-shaped pipe fitting

Abstract

The invention provides a multi-angle adjusting and clamping device for welding of a special-shaped pipe fitting. The multi-angle adjusting and clamping device comprises a bracket, a square rail and afixed gear, a set of sliding supporting seat is slidably connected with the upper end face of the bracket, a set of fixed chucks is connected with the right end face of the bracket in an axial mode, aset of middle gears is connected with the right end face of the bracket in an axial mode, a set of middle gears is connected with the left end face of each sliding supporting seat in an axial mode, aset of center rotating shafts is connected with the upper part of each sliding supporting seat in an axial mode, a set of adjusting pulling seats is slidably connected with each center rotating shaft, and a set of adjusting nuts is connected with the left end face of each adjusting pulling seat in an axial mode. Movable chucks and the fixed chucks are arranged to rotate synchronously, the fact that the welding seam cannot change is ensured, and the welding quality is improved; and by adapting rotating of the pipe fitting, welding is achieved through a overall non-rotating manner, blocking dueto the clamping device is avoided, secondary welding is avoided, one-time welding molding is achieved, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and more specifically relates to a multi-angle adjustable clamping device for welding special-shaped pipe fittings. Background technique [0002] In the production of mechanical parts, it is often encountered that the two groups of component axes are welded at a certain angle. When welding such parts, the clamping device is generally used to clamp and fix the tube, and the tube and the clamping device are rotated at the same time. Circular link of the weld. [0003] For example, application number: CN201611203930.2 invention discloses a clamping device for special-shaped pipe welding, including a work platform, on which a first clamping mechanism for clamping the free end of the first exhaust pipe is arranged, used for clamping and The second clamping mechanism for fixing the muffler body, the third clamping mechanism for clamping the free end of the second exhaust pipe, several clampi...
