Description

Argon arc welding torch tungsten grinding holder

technical field

The utility model relates to a grinding and clamping tool for the tungsten pole of an argon arc welding torch, in particular to a grinding and holding device for the tungsten pole of an argon arc welding torch, which is used for grinding the tungsten pole of the argon arc welding torch.

Background technique

In argon arc welding, tungsten electrode, also called tungsten needle, is an important part of argon arc welding torch. In the process of argon arc welding, the tungsten electrode is the arc starting part of the nozzle. The drawn arc forms high temperature and high pressure, which melts the welding wire, and the angle of its tip affects the weld quality of the workpiece. In order to improve the service life of the tungsten electrode, each manufacturer takes into account the grinding angle of the tungsten electrode when designing the nozzle. The taper inside the nozzle needs to cooperate with the angle of the tungsten electrode in order to exert the highest performance of the welding torch. The angle of the front end of the tungsten electrode is particularly important, not only directly affects the welding quality of the workpiece, but the wrong grinding angle of the tungsten electrode will greatly shorten the life of the tungsten electrode or the nozzle. At present, the grinding of the used tungsten electrode is mainly done by hand-held grinding. First, it is easy to hurt the hands, and second, it is not easy to grasp the angle of grinding. After the tungsten electrode is ground, it needs to be flat. This is to prevent the tip of the tungsten electrode from being burnt too quickly and affecting the stability of the arc. In order to improve the welding quality of the workpiece and the service life of the tungsten electrode, a suitable grinding fixture should be used, especially in the argon arc welding training of electric welders, using a suitable grinding fixture tool to grind the tungsten electrode can achieve twice the result with half the effort Effect.

Contents of the invention

The purpose of the utility model is to provide a tungsten pole grinding holder for an argon arc welding torch, so that the ground tungsten pole tip can meet the welding quality requirements, improve the welding quality of workpieces and prolong the service life of the tungsten pole tip.

The technical solution of the utility model is: the argon arc welding torch tungsten electrode grinding holder includes a fixed base and a movable base, and the movable base is installed on the central rotating shaft of the fixed base through bolts and can rotate on the fixed base; Rotate the shaft, install the collet on the front end of the rotating shaft, install the hand wheel on the rear end, fix the support seat on the movable base, clamp the tungsten pole through the collet, adjust the angle of the movable base, and grind the tungsten pole with a suitable angle.

The beneficial effect of the utility model is that the utility model is used to grind the tungsten pole, the grinding process is stable, and the grinding angle of the tungsten pole is adjustable, which effectively guarantees the grinding quality of the tungsten pole and the welding quality of the workpiece. The tungsten electrode ground by this device can ensure that the angle of the tip of the tungsten electrode after grinding is accurate. During the welding process, the arc can be prevented from blowing, so that the arc formed by the tungsten electrode can be in the best state, and the welding workpiece can be greatly improved. Excellent weld quality, prolong the service life of the tungsten electrode, and have a good use effect. Especially in the argon arc welding training for electric welders, it can achieve twice the result with half the effort, enabling students to master the grinding technology of tungsten electrodes as soon as possible, laying the foundation for welding work.

Detailed ways

The utility model is described in detail below in conjunction with the accompanying drawings. Referring to FIGS. 1 to 5, the argon arc welding torch tungsten grinding holder includes a fixed base 1 and a movable base 2. The movable base 2 is installed on the central shaft of the fixed base 1 by bolts and Can rotate on fixed base 1; Rotating shaft 5 is housed in supporting base 4, chuck 6 is installed in the front end of rotating shaft 5, and handwheel 7 is installed in the rear end, and supporting base 4 is fixed on movable base 2. One end of the movable base 2 is provided with a mounting hole, and the mounting hole of the movable base 2 is set on the central rotating shaft of the fixed base 1, and a bearing is also arranged between the mounting hole of the movable base 2 and the central rotating shaft of the fixed base 1. A spacer 3 is installed above the rotating shaft, and the movable base 2 is fixed on the central rotating shaft of the fixed base 1 by bolts. The support seat 4 includes a seat body and a seat cover, the top of the seat body is provided with a semicircular hole and the semicircular hole of the seat cover is connected by a bolt to form a rotating shaft fixing cylinder, and the seat body is fixed on the movable base 2 by bolts; There are two rows of bolt holes, which can adjust the front and rear positions of the support base 4 above the movable base 2.

There are two ways to install the rotating shaft 5

Embodiment one

The front end of the rotating shaft 5 is provided with a tungsten pole jack, and a fixed cover is installed outside the rotating shaft 5, and a bearing is installed between the rotating shaft 5 and the fixed cover, and the fixed cover is fixed in the rotating shaft fixed cylinder of the support base 4.
