Three-hole flange automatic pin retreating mechanism

Abstract

The invention discloses a three-hole flange automatic pin retreating mechanism. The three-hole flange automatic pin retreating mechanism comprises a main positioning plate. A flange base plate is fixed to one side of the main positioning plate. A first air cylinder, a second air cylinder and a third air cylinder are fixed to the other side of the main positioning plate. A fourth air cylinder is arranged in the center of a triangle defined by the first air cylinder, the second air cylinder and the third air cylinder. Three positioning cores and two semicircular positioning blocks are installed on a first positioning plate. The ends of the first air cylinder, the second air cylinder and the third air cylinder penetrate through the main positioning plate and then are each connected with a pressing block. According to the three-hole flange automatic pin retreating mechanism, an advancing and retreating mechanism is omitted completely. In the use process, the flange positioning blocks and the positioning cores can realize automatic retreating and advancing through driving with the air cylinders, and an operation procedure is omitted for workers. The three-hole flange automatic pin retreating mechanism lowers the complexity of a tool, saves space, reduces the weight of the tool and reduces the production cost.

Description

technical field [0001] The invention relates to an automatic cancellation mechanism for a three-hole flange. Background technique [0002] During the production process of the exhaust system, there are many three-hole flanges used for air outlet or air intake that need to be welded, and the flanges need to be pressed tightly during welding. The blue clamping mechanism withdraws or advances as a whole, which causes the part of the tooling to look bloated, and the operation is cumbersome, and increases the overall weight of the tooling, which is inconvenient for workers to change the tooling. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a three-hole flange automatic cancellation mechanism, which completely omits the forward and backward mechanism, reduces one operation procedure for workers, reduces the complexity of tooling, saves space, and reduces the weight of tooling. Reduced production cost...
