Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire feeding, in particular to a wire fixing and feeding structure for a welding robot. Background Technique
[0002] A welding wire is a welding material in the form of a filler metal or a metal wire that also serves as a conductor. A welding robot is equipped with a welding torch or a welding (cutting) gun at the end flange of an industrial robot, enabling it to perform welding, cutting, or thermal spraying. During robotic welding, the welding torch needs to be aligned with the pipe gap, and the welding wire is used to fill it. An automated wire feeding system is provided in the wire welding robot, including a wire feeding hose, a spool of welding wire, a wire feeding mechanism, etc. The wire is delivered to the designated position through configuration. When the welding torch is welding, the welding wire needs to be consumed, and the sensor will transmit the welding information to the automatic wire feeding system to complete the automatic wire feeding process.
[0003] During the production of welding wire, due to unqualified wire drawing equipment, burrs are likely to appear on the surface of the wire. When the wire with burrs enters the wire feeding hose of the welding torch, it will rub against the hose wall and cause vibration. When the vibration gradually approaches the welding torch and enters the contact tip, wire feeding instability, intermittent welding, or jamming will occur. Moreover, the current wire feeding device for welding wire cannot clean the burrs on the surface of the wire. Therefore, in view of the above problems, a wire fixing and feeding structure for a welding robot is proposed. Content of the Utility Model

[0024] As a further improvement of the present utility model, as Figure 2 shown, the number of the grinding plates 13 is two, and they are symmetrically distributed at both ends of the welding wire 4. The grinding effect is improved by arranging multiple grinding plates 13.
