Problems solved by technology

For the problem of excessive resistance of the wire reel, if the damping force of the wire reel is simply reduced, the wire reel will easily rotate and cause the welding wire to scatter automatically; Subsequent welding is inconvenient
[0003] At present, it is also proposed to add a spring damper to the rotating shaft of the wire reel. The spring damper is an internal damper, and its damping is generated by the friction inside the material or between structural parts. The friction of the internal structure material becomes serious, the surface of the material becomes rough, and the friction force becomes larger, which makes the pulling force of the welding wire larger, which affects the stability of the wire feeding, resulting in uneven welding results

Abstract

The invention provides a variable damping type scroll fixing device and welding equipment. The variable damping type scroll fixing device comprises a scroll support, a variable damping assembly and a scroll shaft. The scroll support has a shaft hole. The variable damping assembly comprises an electromagnetic brake, a connecting shaft and a damping regulator, the electromagnetic brake and the damping regulator are arranged on the connecting shaft in a sleeving mode and arranged on one side of the wire disc support, and the output end of the connecting shaft penetrates through a shaft hole of the wire disc support. The electromagnetic brake and the damping regulator are both electrically connected to the welding power source, and the electromagnetic brake releases or locks the connecting shaft based on a received start-stop signal from the welding power source; the damping regulator receives a damping control signal which is output by the welding power source and is related to the welding wire conveying state when the electromagnetic brake releases the connecting shaft and applies adjustable damping force to the connecting shaft based on the received damping control signal. The scroll shaft is arranged on the other side of the scroll support, and the scroll shaft is connected to the output end of the connecting shaft and is in linkage with the connecting shaft.

Description

technical field [0001] The invention relates to the field of welding, and in particular to a variable damping wire reel fixing device and welding equipment. Background technique [0002] As welding robots are widely used in the manufacturing industry, more and more attention is paid to welding quality. One of the factors affecting welding quality is the stability of wire feeding. Factors affecting the stability of wire feeding include excessive resistance of the wire reel, hard bending of the welding wire, and uneven thickness of the welding wire. For the problem of excessive resistance of the wire reel, if the damping force of the wire reel is simply reduced, the wire reel will easily rotate and cause the welding wire to scatter automatically; Subsequent welding is inconvenient. [0003] At present, it is also proposed to add a spring damper to the rotating shaft of the wire reel. The spring damper is an internal damper, and its damping is generated by the friction inside...
