Convenient connecting mechanism for welding tongs and welding rod for shielded metal arc welding

Abstract

The invention relates to the technical field of welding manufacturing, and discloses a convenient connecting mechanism for welding tongs and a welding rod for shielded metal arc welding. The connecting mechanism comprises a holding device; pressing rods are movably connected outside the holding device; trigger blocks are movably connected inside the pressing rods; a motor is movably connected inside the holding device; a threaded screw rod is movably connected outside the motor; a threaded sliding sleeve is movably connected outside the threaded screw rod; pull rods are movably connected outside the threaded sliding sleeve; sliding parts are movably connected outside the pull rods, and sleeved with a shell; electric conduction devices are movably connected inside the shell; a supporting pipe is movably connected outside the electric conduction devices; clamping devices are movably connected inside the supporting pipe; and and telescopic rods are movably connected inside the clamping devices. The connecting mechanism has the advantages of being stable in clamping and very convenient to assemble and disassemble, and therefore the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of welding manufacturing technology, in particular to a convenient connection mechanism between welding tongs and welding rods for electrode arc welding. Background technique [0002] Arc welding refers to the use of arc as a heat source and the physical phenomenon of air discharge to convert electrical energy into thermal and mechanical energy required for welding, so as to achieve the purpose of connecting metals. When using arc welding for welding, welding tongs are required Clamp the welding rod, and then energize it, but when clamping, it is easy to fall off due to the instability of the clamping, which will affect the welding quality and may cause harm to the user. Therefore, a stable and stable clamping is required. A relatively convenient device to improve existing facilities. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a convenient connecti...
