Welding machine overlapping wire device

Technical Field

The utility model relates to the field of welding processing, in particular to a welding machine lap joint line device.

Background

The current welding overlapping wire mode mostly adopts the mode that a welding tongs clamps the workpiece to be welded. However, the use scenario of the overlapping wire mode is more restricted: firstly, when a large-sized workpiece is encountered, the workpiece cannot be clamped on the surface of the workpiece, and the workpiece can only be clamped in a mode of modifying the surface of the workpiece, so that the clamping is very troublesome and damages the surface of the workpiece; secondly, the contact area of the welding tongs when the welding tongs are clamped on the surface of a workpiece is small, so that the over-current is possibly insufficient, and the welding quality is influenced; thirdly, the connection mode of the clamping of the welding tongs is not stable. The patent of grant publication No. CN2614830Y discloses a magnetism is inhaled formula arc welding machine zero line and is inhaled quick lap joint machine, and zero line in this utility model only end of a thread position contact is welded the work piece, so it is little still to probably appear the overlap area, crosses the insufficient problem of electricity.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a welding machine lap joint line device which can stably and conveniently lap joint a zero line on the surfaces of most of workpieces to be welded, and fully electrify the zero line to ensure the welding quality.

The utility model is realized by the following technical scheme:

the utility model provides a welding machine overlap joint line device, includes from last splint to distributing in proper order down, permanent magnet and electrically conductive metal sheet, through two bolted connection between metal sheet and the splint to press from both sides the permanent magnet tight in the centre, need lapped wire pressure between bolt nut and splint, be equipped with the insulating layer between permanent magnet and the metal sheet.

Further: the insulating layer is a nylon plate.

Further: and the outer layer of the permanent magnet is wrapped by an insulating adhesive tape.

Further: the metal plate is made of brass.

Further: be equipped with the handle on the splint, the handle is made by the nylon materials.

Further: the lower bottom surface of the metal plate is provided with a V-shaped groove, and when the cylindrical surface is welded, the V-shaped groove can be well attached to the cylindrical surface.

Compared with the prior art, the utility model has the following advantages:

firstly, when the lap joint is needed, the device is directly placed on the surface of a workpiece to be welded, the metal plate is tightly pressed on the surface of the workpiece by the magnetic force of the permanent magnet, and the metal plate is connected with a lead through a bolt and a nut, so that the operation of the lap joint is realized. The device is convenient to install.

And secondly, the magnetic force of the permanent magnet firmly presses the metal plate on the surface of the workpiece, and the lap joint state is stable.

And thirdly, the contact area between the metal plate and the workpiece is large, and sufficient over-current can be ensured, so that the welding quality is ensured.
