Problems solved by technology

[0003] In view of this, Chinese Patent No. CN209140132U proposes a door frame welding automation equipment, which has the advantages of better improving the flexibility of welding robots, improving welding quality and welding efficiency, and Chinese Patent No. CN205200873U proposes an automatic welding process for aluminum alloy door frames Equipment, Chinese Patent No. CN208575421U proposes a welding device for automobile door frame cover plates. None of the above patents involves the positioning of the door frame before welding. When welding the door frame, it is necessary to determine the position of the welding point in advance to ensure the accuracy of the welding point. The welding position is not accurate, it is easy to cause damage to the door frame, and it is easy to reduce the service life of the door frame

Abstract

The invention discloses an automatic door frame welding device. The automatic door frame welding device comprises a workbench, wherein supporting legs are fixedly arranged at four corners of the bottom end of the workbench; through grooves are formed in four corners of the top end of the workbench; and one of the sides of the inner walls of the four through grooves is in threaded connection with one of the ends of four screw rods. According to the automatic door frame welding device, a positioning pin is arranged, a driving motor switch is turned on, a driving motor drives a lead screw to rotate, the lead screw drives a penetrating plate to horizontally move, the penetrating plate drives a connecting plate to move, the connecting plate drives a fixing plate to horizontally move, the fixingplate drives a sliding rod to horizontally move in a first sliding groove, so that a moving plate is driven to horizontally move, a sliding block is slid, the sliding block drives an electric telescopic rod to move, the electric telescopic rod drives the positioning pin to horizontally move, an electric telescopic rod switch is turned on, the electric telescopic rod drives the positioning pin tomove downwards, and then a to-be-welded door frame can be positioned in advance, so that the accuracy of the door frame during welding is kept, and the service life of the door frame is prolonged.

Description

technical field [0001] The invention relates to a welding device, in particular to an automatic door frame welding device. Background technique [0002] For metal door frames, during processing, it is necessary to weld the outer door frame plate and the inner door frame plate to the bottom plate of the door frame. Before welding, the outer door frame plate and the inner door frame plate are spot-welded on the door frame bottom plate, and a welding robot is needed to weld the outer door frame plate and the inner door frame plate to the door frame bottom plate. [0003] In view of this, Chinese Patent No. CN209140132U proposes a door frame welding automation equipment, which has the advantages of better improving the flexibility of welding robots, improving welding quality and welding efficiency, and Chinese Patent No. CN205200873U proposes an automatic welding process for aluminum alloy door frames Equipment, Chinese Patent No. CN208575421U proposes a welding device for auto...
