Description

Technical Field

[0001] The present invention relates to the field of auxiliary clamping devices, in particular to a clamping arc striking and extinguishing device. Background Art

[0002] The critical current for arc occurrence is lower than this current value, and no arc will occur even if the voltage is high.

[0003] Arc strike plates are used for weld seams. The weld seam's starting and ending points often create a welded joint cutout, resulting in butt welds with various shapes, including straight-edge, single-sided V-shaped, double-sided V-shaped, U-shaped, K-shaped, and X-shaped. Concave welds often form at the weld's starting and ending points due to a lack of penetration. To prevent cracks and stress concentration after application, the ends should be welded to the arc strike plate, and the excess material removed to avoid reducing the weld's cross-section.

[0004] When the arc striking and extinguishing plate is used for welding as mentioned above, the object is directly placed on the arc striking and extinguishing plate, which will cause damage to the arc striking and extinguishing plate. Therefore, each welding requires the consumption of steel of the arc striking and extinguishing plate, and a lot of steel is wasted. For this reason, a clamping arc striking and extinguishing device is needed to facilitate the clamping of the discarded welding wire, so that the discarded welding wire can be used as an arc striking and extinguishing source to reduce the steel consumption of the arc striking and extinguishing plate. Summary of the Invention

[0014] The beneficial effects of the present invention are:

[0015] 1) Insert the bottom plate into the carrier plate, and the distance between the inner side of the carrier plate and the bottom end of the work plate is equal to the thickness of the bottom plate. Use the distance between the bottom end of the guide tube and the top end of the bottom plate to be equal to the distance between the bottom end of the placement slot and the bottom end of the work plate, so that the top end of the bottom plate is in contact with the bottom end of the work plate. At the same time, align the guide tube with the placement slot, and then align the limiting hole with the through hole. Pass the insertion rod through the through hole and the limiting hole so that the bottom plate can be initially fixed on the carrier plate.

[0016] 2) Turn the screw, the screw drives the connecting plate to move upward, and the connecting plate drives the pressure plate to move upward, so that the pressure plate rests against the short side of the top plate, so that the long side of the top plate can press the work plate downward more tightly, thereby achieving the effect of conveniently clamping the work plate between the top plate and the bottom plate. Reverse the operation to release the restriction of the limiter on the top plate.

[0017] 3) Rotate the support rod to align the socket with the catheter, and align the socket, catheter and placement slot. At this time, push the slider to move along the round rod. The slider moves with the spline, so that the spline engages with the keyway, thereby fixing the round shaft, thereby limiting the position of the support rod, inserting the waste welding wire into the socket, the waste welding wire passes through the catheter, and then enters the placement slot, so that the waste welding wire can be aligned and clamped, achieving a convenient alignment and clamping effect for the waste welding wire.
