Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model; Do not doing under the situation of opposite explanation; The noun of locality that uses as " on ", D score, " under " wait usually all to direction shown in the drawings with " vertical direction ", or be directed against each the parts mutual alignment relationship description word on vertical or the gravity direction.
As shown in Figure 1, the utility model discloses a kind of electric conduction device for welding, this electric conduction device for welding comprises drive unit 1, electric-conductor 3 and earth connection 4, and wherein, drive unit 1 connects and drives electric-conductor 3, and electric-conductor 3 forms with earth connection 4 and is electrically connected.When welding was used, drive unit 1 can promote electric-conductor 3, and electric-conductor 3 is contacted with the outer wall of welding work pieces especially pipe fitting, and electric-conductor 3 is electrically connected with earth connection 4 formation, earth connection 4 ground connection, thus can lead ground by the electric current on the weld-end fittings when welding.Because electric-conductor 3 is directly to be promoted to contact with the pipe fitting outer wall by drive unit 1; When instant pipe fitting rotated, what form between electric-conductor 3 and the pipe fitting outer wall was electrically connected also enough reliably, and the electric conduction device for welding in this execution mode is simple in structure; Easy for installation, below will address.Wherein, drive unit 1 can be cylinder, hydraulic cylinder or spiro driving device or the like, is preferably air cylinder driven in this execution mode, and is as shown in Figure 1.
In addition, as shown in Figure 1 for being connected of the installation that makes things convenient for electric-conductor and electric-conductor and drive unit, said electric-conductor 3 is installed on the storage tank 2, storage tank 2 is connected with the output shaft of said drive unit 1, thereby makes drive unit can promote electric-conductor.Wherein, storage tank 2 can correspondingly design according to the shape of electric-conductor, and electric-conductor is installed in wherein.Described electric-conductor 3 can be a various ways, is preferably the copper wire conduction brush in this execution mode, and is as shown in Figure 1.Because the copper wire conduction brush forms soft the contact with weld-end fittings, thereby can have enough contacts area, forms firm electrical connection.
The electric conduction device for welding of this execution mode when mounted; Its mounting structure is as shown in Figure 1; The pipe fitting 8 and the workpiece erecting bed 7 of locating, support this pipe fitting that comprise required welding; Wherein, the electric-conductor 3 of electric conduction device for welding contacts with the intimate of said pipe fitting 8, and electric conduction device for welding is fixedly installed on the said workpiece erecting bed 7.As shown in Figure 1, the electric conduction device for welding of this execution mode is installed in the side of workpiece erecting bed 7, thus it is little to take up room.After pipe fitting 8 was installed on the workpiece erecting bed 7, the drive unit of electric conduction device for welding 1 was released said electric-conductor 3, made the outer surface of itself and pipe fitting 8 form firm electrically contacting, and the earth connection 4 through being connected with electric-conductor 3, and the electric current on the pipe fitting 8 is led ground.When accomplishing welding, then drive unit 1 bounces back, and electric-conductor 3 disengages with pipe fitting 8, and this moment, electric conduction device for welding did not influence the peace loading, unloading fortune of pipe fitting 8 etc. basically.
