Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, specifically relating to a welding machine ground wire clamping device. Background Technology

[0002] The welding machine grounding clamp is used to connect the welding machine and the workpiece to ensure that the welding current can flow back to the power source stably. The grounding clamp is a connecting device with one end connected to the grounding wire and the other end connected to the pipe to be welded. The grounding wire is tightly connected to the grounding clamp using grounding clips or bolts to ensure that the current is stable during the welding process, thereby ensuring the stability of the welding process and the quality of the weld.

[0003] The technology for connecting ground wires and ground clamps is quite mature in China. However, there are still some drawbacks in the connection between the ground clamp and the component to be welded. In construction projects, most equipment is assembled on-site. Pipes serve as the link between various equipment, and welding is the key to this connection. The quality of pipe installation directly affects the service life of the equipment, while the quality of welding directly affects the service life of the pipes. Currently, construction companies purchase ground clamps, which have certain drawbacks, such as: a small contact area with the weldment, making it prone to arc damage; and the tendency to fall off during clamping due to vibration, which, if not detected in time, can lead to breakdown in the ground wire connection area. Utility Model Content

[0004] The purpose of this utility model is to provide a welding machine ground wire clamping device to solve the problems of existing welding machine ground wire clamps being not securely fastened, easily falling off, and causing damage to the welded parts due to insufficient contact surface when clamping the welded parts.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a welding machine ground wire clamping device, wherein the device includes: a ground wire clamping component and a locking component for fixing and locking one end of the ground wire clamping component; the ground wire clamping component includes: a pair of metal U-shaped plates, each of the upper and lower sides of the U-shaped plates is machined with several semi-circular grooves of different sizes for use as clamping parts for the parts to be welded, and openings are machined on the left and right sides of the U-shaped plates for use as ground wire clamping fastening parts, the two U-shaped plates are placed symmetrically, and the area formed by the space in the middle is used as a ground wire clamp holding part.

[0006] The aforementioned welding machine ground wire clamping device, wherein the locking component includes two locking plates and two locking bolts.

[0007] In the aforementioned welding machine ground wire clamping device, one end of the locking plate has a circular opening and the other end has a U-shaped opening, through which the locking bolt can pass.

[0008] In the aforementioned welding machine ground wire clamping device, the front side of the concave plate has an extension portion, and one end of the extension portion is provided with a round hole for installing a locking component.

[0009] In the above-mentioned welding machine ground wire clamping device, the concave plate is a metal plate with a thickness of 0.2-5mm.

[0010] In the aforementioned welding machine ground wire clamping device, the size of the semi-circular groove gradually increases along one side, and two concave plates cooperate to form a circular part clamping part of different sizes to be welded, so as to adapt to parts of different sizes to be welded.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the welding machine ground wire clamping device provided by this utility model can, on the one hand, clamp the welding pipe through a suitable clamping part, which can ensure the quality of the clamping area after welding; on the other hand, through one-time clamping and locking, there is no instantaneous detachment that could cause the ground wire clamp to fall off and injure nearby personnel or equipment, thus improving the safety of use.
