Description
Technical Field
The utility model relates to an electrode holder, in particular to a method for fixing a welding rod by the electrode holder.
Background
The patent publication of Chinese utility model, 7 and 30 in 2008, discloses a stick-shaped three-point electrode holders (patent No. 200720013447.8), the main contents of which are: the front section of the energizing guide rod of the electric welding pliers is provided with a fork-shaped clamping jaw with two clamping surfaces, the rear section of the fork-shaped clamping jaw is provided with a supporting lug, the rear of the supporting lug is provided with a pin sleeved with a spring, the outer surface of the front section of the energizing guide rod is coated with an insulating material shell, the rear section of the energizing guide rod is positioned in a handle, the front part of the rear section of the energizing guide rod is provided with a screw hole, a fastening pin is arranged in the screw hole, a fastening piece for connecting a cable with the energizing guide rod is arranged behind the fastening pin, the metal clamping jaw of the movable pressing rod is one, the middle of the metal clamping jaw is provided with a supporting lug corresponding to the energizing guide rod, the shaft holes of the metal clamping jaw are internally provided with pin shafts, the position of the pressing rod which is coated outside the metal clamping jaw and extends to the notch on the handle and is opposite to the pin of the energizing guide rod is provided with a through hole. Its disadvantages are: 1. because the movable pressure bar of the electrode holder is a lever taking the support lug as the axis, the higher the rear surface is, the lower the front end is, and when welding rods are not clamped, the rear spring of the support lug is in a loose high-top state, so that the front end position of a metal clamping jaw connected with the movable pressure bar is the lowest, and the metal clamping jaw falls below the plane of a fork clamping jaw of a lower electrified guide rod. The welding rod is clamped at the upper edge of the plane of the fork-shaped clamping jaw, so that the welding rod is pressed hard to press the raised position behind the movable pressing rod when the welding rod is clamped, and the welding rod is hard to clamp at first because the welding clamp does not have a high-pressure handle to act as moment. 2. The front end of the lug of the electrode holder is too low, and the rear end of the lug is too high, so that the distance between the movable compression bar positioned at the spring part and the insulating cover outside the electrified guide rod is too large, and fingers can touch the electrified spring, and the national safety verification standard of electric products is not met. If the thickness of the movable compression bar is increased downwards, namely the thickness of the spring slot hole is increased, or the thickness of the electrified guide rod insulating cover is increased upwards, when welding rods are clamped, the two parts are propped up and dead, the spring cannot work, and the welding tongs cannot be used. 3. At present, all the electrified guide rods of various electrode holders adopt copper materials with good electric conductivity, but when the electrode holders are used, electric discharge can be generated between the electrode and the electrode holders, and copper is not resistant to arc striking, so that the electrode holder electrode parts of the electrode holders are struck into pits and uneven, and the service life of the electrode holders is shortened. For this purpose, electrode holders disclosed in patent document 201010259559.8 of China have been devised. When the welding rod is fixed by the existing electric welding machine, the welding rod can be clamped only by opening the clamp and then loosening the acting force of the opening clamp.

A method for fixing a welding rod of an electrode holder according to claim 1, 2 or 3, wherein a blade extending in the extending direction of the conductive holding rod is provided on a side of the conductive holding rod which contacts the welding rod; when the conductive clamping rod is used for fixing the welding electrode, the cutting edge cuts into the welding electrode, so that the welding electrode is prevented from rotating relative to the conductive clamping rod.
9. A method for fixing welding rods of an electrode holder according to claim 1, 2 or 3, wherein the conductive clamping rod is internally provided with an air inlet channel and an air outlet channel, the inlet of the air inlet channel is communicated with the air inlet main port, the air inlet channel and the air outlet channel extend from one end of the conductive clamping strip to the other end, the outlet of the air inlet channel is communicated with the inlet of the air outlet channel through a communication channel positioned in the conductive clamping strip, and the outlet of the air outlet channel is positioned on the end face of one end of the conductive clamping rod connected with the handle; in the electric welding process, cooling gas is blown into the air inlet main port through the air blower, and the blown cooling gas flows out of the outlet of the air outlet channel after sequentially flowing through the air inlet channel and the air outlet channel, so that the conductive clamping rod is cooled, and the conductive clamping rod is prevented from losing effective fixation of the welding electrode due to temperature rise of the conductive clamping rod during electric welding.
