Description

Tungsten electrode clamping tool Technical Field The utility model relates to braiding equipment, in particular to a tungsten electrode clamping tool. Background In the development process of the welding technology, the tungsten electrode is used as a common electrode material and is widely applied to welding processes such as Tungsten Inert Gas (TIG) welding and the like. Tungsten electrodes deliver current to the workpiece during TIG welding, which is the basis for the generation of a welding arc. When the tungsten electrode is used, an operator generally divides one tungsten electrode into 5 sections (30 mm/section) firstly, then the tungsten electrode is subjected to sharpening and arc striking, and the tip is burnt or melted and then is ground again, and the process is repeated until the tungsten electrode cannot be ground. In order to ensure welding quality and stability, a tungsten electrode clamping tool is used for clamping a tungsten electrode, so that the tungsten electrode can be kept in a correct position and posture in the welding process, and the tungsten electrode can be conveniently replaced. The elastic chuck and the internal screw tap nut used in the existing tungsten electrode clamping tool structure are overlarge in volume, and cannot be effectively ground for tungsten electrodes with the length below 22mm, so that each tungsten electrode can cause the tungsten electrode with the length of 110mm to be unusable, the tungsten electrode is large in waste amount, poor in practicality and high in use cost. For the above reasons, it is necessary to design a tungsten electrode clamping tool with small volume, low energy consumption and high practicability. Disclosure of utility model In view of the above problems in the prior art, the utility model aims to provide a tungsten electrode clamping tool, which achieves the purposes of small volume, low energy consumption and high practicability. In order to achieve the above purpose, the technical scheme of the utility model is as follows: The utility model provides a tungsten electrode clamping frock, includes handheld pole, conical nut and collet chuck, is provided with on the handheld pole with conical nut threaded connection's nut seat, and collet chuck is located handheld pole and conical nut inside, collet chuck is including through connection's elastic clamping portion and auxiliary clamping portion, a plurality of movable mouths have been seted up to the week side of elastic clamping portion, and the lower extreme of movable mouths to auxiliary clamping portion extends, set up on the nut seat with auxiliary clamping portion complex spacing mouth for the saving and the stable centre gripping of tungsten electrode. Preferably, the opening at the upper end of the elastic clamping part is smaller than the inner diameter of the auxiliary clamping part, the auxiliary clamping part is communicated with the handheld rod, and the length of the auxiliary clamping part is smaller than the length of the handheld rod. Preferably, an embedded groove is formed in the lower side of the outer portion of the elastic clamping portion, an elastic ring is sleeved in the embedded groove, and the elastic ring is made of elastic materials.
