Full-automatic circular welding machine for welding gap between roller and plug

Abstract

The invention discloses a full-automatic circular welding machine for welding a gap between a roller and a plug. The welding machine comprises a control mechanism, a transmission mechanism, a diameter measuring mechanism, a lift mechanism, a center mechanism, a laser probe mechanism and a welding pistol mechanism, wherein the transmission mechanism, the diameter measuring mechanism, the lift mechanism, the center mechanism, the laser probe mechanism and the welding pistol mechanism are all connected with the control mechanism; the transmission mechanism is provided with a rotatable conveyer belt, an initial sensing switch, a stop sensing switch and a rise sensing switch; the initial sensing switch, the stop sensing switch and the rise sensing switch are horizontally and sequentially arranged along the rotation direction of the conveyer belt; the diameter measuring mechanism is used for detecting the diameter of the roller and transmitting diameter information of the roller to the control mechanism; the control mechanism is used for changing lift displacement of the lift mechanism according to the diameter information; the center mechanism is used for fully and tightly jacking up the plug; a laser probe is used for detecting whether the plug is jacked up tightly enough; and a welding pistol is used for welding. In the welding machine, full-automatic operation is completely adopted in the whole process, and welding of rollers in any size is realized. Moreover, due to the adoption of accurate positioning and automatic welding, the welding machine has the advantages of high welding accuracy, stable welding quality and the like.

Description

technical field [0001] The invention relates to the field of ring welding machines, in particular to a full-automatic ring welding machine for welding gaps between plate rolls and plugs. Background technique [0002] The version roller, as the core part of the printing machine, needs to be reprocessed and manufactured according to the different packaging bags to be printed, that is, different version rollers need to be processed and manufactured according to different printing products; at the same time, both ends of the version roller are Plugs need to be provided. After the plugs are preliminarily fixed on both ends of the plate roll, there is often an annular gap between the plug and the plate roll, which needs to be filled by welding at present. [0003] The automatic ring welding machine is a general automatic welding equipment that can complete various circular welds; the traditional automatic ring welding machine generally includes a machine base, a power device and a...
