The utility model discloses a mechanical part welding auxiliary device with a welding fume filtering function, particularly relates to the technical field of mechanical part welding, and aims to solve the problems that a large amount of harmful gas is often generated during welding, so that an operator inhales the harmful gas, and the harmful gas harms a human body. The device comprises a base and a protective cover, a first connecting pipe is fixedly arranged at an air inlet of an air extracting pump, air extracting pipes which are symmetrically distributed fixedly penetrate through the outer side of the first connecting pipe, a second connecting pipe is fixedly arranged at an air outlet of the air extracting pump, and a filter is fixedly arranged on the side, close to the air extracting pump, of the protective cover. Harmful gas in the protective cover is sucked into the inner suction pipe through suction force generated by the suction pump, enters the air inlet of the suction pump through the first connect
