Abstract

The invention discloses a circular stainless steel common plate flange wind pipe welding connection mechanism. The mechanism comprises a support plate; two support columns are arranged at the upper end of the support plate; chutes are vertically formed in the upper sides of the front ends of the two support columns; first lead screws are vertically and rotationally connected into the chutes through rolling bearings; the upper ends of the first lead screws penetrate through the rolling bearings, and are fixedly connected with turntable discs; thread sleeves are in threaded connection to the rodwalls of the first leas screws; one sides of the thread sleeves are fixedly connected with transverse plates; the lower ends of the transverse plates are hinged with two clamping plates with arc structures through hinges; multiple universal balls, uniformly distributed, are fixedly connected to one opposite sides of the two clamping plates; and the lower sides of the ends, far from the universalballs, of the clamping plates are rotationally connected with sleeves through shaft pins. The mechanism is convenient for workers to quickly join welding lines and to rotationally weld wind pipes, accelerates the welding speed, meanwhile, can counteract a certain welding stress, and improves the welding quality.

Description

technical field [0001] The invention relates to the technical field of common-plate flange welding, in particular to a circular stainless steel common-plate flange air duct welding connection mechanism. Background technique [0002] The common plate flange is mainly connected by corner codes, flange clamps, and flanges integrally connected with the air duct. Although the cost of this form of air duct is low (reducing the amount of angle steel and the labor required for making angle steel flanges), But the actual application is not as strong as the angle steel flange, and the air leakage is also large, and it must be processed by machine tools. It is almost impossible to make it by hand. It is usually only used in fresh air systems, air conditioning systems, etc., and the smoke exhaust system often uses angle steel. Flange-connected air ducts. However, civil air defense projects are absolutely not allowed to use a common plate flange connection. [0003] In the prior art, w...
