[0025] refer to Figures 1 to 3 As an object of the present utility model, a dust suction device for welding is provided, which includes a dust suction component 1, a blowing component 2, and a sealing component 3. The dust suction component 1 is connected to a dust suction source, the blowing component 2 is connected to a blowing source, and the sealing component 3 has a sealing cavity and is used to abut and seal a dust removal surface. For example, when friction welding is used to weld an oil tank and a weldment, the dust removal surface is the surface of the welding part and the surrounding area of ​​the oil tank and the weldment where dust such as welding shavings will be generated and accumulated during the welding process, hereinafter referred to as the surface of the oil tank and the weldment. The blowing component 2 blows the dust generated by welding on the dust removal surface, and the dust blown off the dust removal surface is sealed in the sealing cavity. The dust suction component 1 sucks the dust from the sealing cavity and discharges it. In this way, by using the welding dust suction device, the dust removal surface of the surface of the weldment and the box body, for example, can be wrapped up through the sealing component 3 during the welding process, and the dust on the dust removal surface can be blown away by the blowing component 2 and diffused in the sealing cavity of the sealing component 3, and then the dust suction component 1 is used to suck out the dust in the sealing cavity and discharge it, so that the discharged dust can be centrally processed, thereby achieving the beneficial technical effects of good dust removal effect and high degree of automation.

In this way, the dust suction connector 11 and the connecting block 12 can be reliably and firmly fixed to each other.

[0028] Please refer to further Figure 1 Specifically, a first blowing inlet 141 connected to a blowing source is provided on the second dust collection sleeve 14, a blowing channel 142 is provided in the second dust collection sleeve 14, a circle of blowing grooves 211 is provided on the side surface of the blowing sleeve 21 facing the second dust collection sleeve 14, and a plurality of blowing holes 212 are evenly and throughly provided in the inner wall of the blowing sleeve 21.

The blowing channel 142 is located between the blowing inlet and the blowing groove 211 and connects the two. The blowing groove 211 is connected to each blowing hole 212, and each blowing hole 212 blows air into the sealed cavity. Therefore, the airflow of the blowing source can smoothly flow to each blowing hole 212 through the first blowing inlet 141 in a distributed manner, and the blowing holes 212 can evenly blow air to the dust removal surface, thereby ensuring that the dust on the dust removal surface is blown away and diffused.

The second blowing inlet 221 blows air to the connection between the connecting block 12 and the first dust suction sleeve 13, especially the corner, so as to prevent dust from accumulating at the connection or even blocking the airflow channel. In this embodiment, the second blowing inlet 221 blows the airflow from the blowing source from the connection to the dust suction interface, so that the dust can be sucked away faster in cooperation with the suction source.

In this case, by adopting this structure, the sealing sleeve 31 and the blowing sleeve 21 can be accurately fixed on the axis.

[0031] Please refer to further Figure 1 Preferably, pairs of limiting holes are correspondingly provided on the connecting block 12 and the first dust collection sleeve 13, and a limiting pin 5 is inserted in each pair of limiting holes. A pair of recessed parts 121 are provided on the connecting block 12, and a locking hole 122 for locking with a locking member (not shown) for fixing and connecting the connecting block 12 is provided on the bottom surface of the recessed part 121. For example, the locking member can fix the connecting block 12 to a bracket supporting the dust collection source. In this way, the connecting block 12 is reliably fixed with the first dust collection sleeve 13 in the transverse direction, that is, in the flow direction of the airflow, and is fixed by the locking member in the longitudinal direction, that is, perpendicular to the flow direction, so that the connecting block as a whole is firmly fixed in both vertical directions.

[0032] Please refer to further Figure 3Specifically, the first dust collection sleeve 13 and the second dust collection sleeve 14 are both hollow cylindrical in shape. The first flange 131 of the first dust collection sleeve 13 is plugged into the first groove of the connecting block 12.

Each positioning hole 132 and 144 can be a threaded hole, and the positioning member can be a screw or bolt threadedly connected to each threaded hole. Therefore, the first dust collection sleeve 13, the second dust collection sleeve 14 and the connecting block 12 are mutually limited in the circumferential direction, which further ensures the reliability of the connection and fixation between them.
