Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of argon arc welding, in particular to an argon arc welding gun mounting bracket. Background Art
[0002] Argon arc welding is a welding technology that uses argon as a shielding gas, also known as argon gas shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air outside the welding area to prevent oxidation of the welding area.
[0003] Argon arc welding technology is a welding technology based on the principle of ordinary arc welding. It uses argon gas to protect metal welding materials. Through high current, the welding materials are melted into liquid on the base material to form a molten pool, so that the metal to be welded and the welding materials achieve metallurgical bonding. Since argon gas is continuously supplied during high-temperature molten welding, the welding materials cannot come into contact with oxygen in the air, thereby preventing oxidation of the welding materials.
[0004] The internal capacity of a TIG welding torch is limited. During TIG welding, the shielding gas supplied through the torch in a short period of time is relatively small, and the weld still has the risk of oxidation. Therefore, to ensure welding quality, it is sometimes necessary to reduce the welding speed, allowing the shielding gas to accumulate over time and protect the weld front. However, this will reduce welding efficiency. Utility Model Content
[0005] In order to solve the above problems, the utility model provides an argon arc welding gun mounting bracket, which can provide additional inert gas to protect the weld and speed up the welding rate.
[0006] To this end, the technical solution of the utility model is: an argon arc welding gun mounting bracket, comprising a welding gun, a first mounting bracket, a horizontal guide rail and a vertical guide rail; the vertical guide rail is slidably mounted on the horizontal guide rail through a first movable block, the first mounting bracket is slidably mounted on the vertical guide rail through a second movable block, and the welding gun is mounted on the first mounting bracket; a third movable block is also slidably mounted on the vertical guide rail, a second mounting bracket is mounted on the third movable block, an inert gas injection ring is provided on the second mounting bracket, a plurality of injection holes are provided on the lower surface of the inert gas injection ring, and the lower end of the welding gun passes through the inert gas injection ring.
[0007] On the basis of the above solution and as a preferred solution of the above solution: the lower end surface of the inert gas injection ring is a conical surface, the injection holes are placed on the conical surface, and the air flow direction of the injection holes is toward the bottom end of the welding gun.
[0008] On the basis of the above solution and as a preferred solution of the above solution: the welding gun and the inert gas injection ring are synchronously lifted and lowered along the vertical guide rail through the second movable block and the third movable block.
[0009] On the basis of the above solution and as a preferred solution of the above solution: a horizontal driving module for driving the first movable block to move in translation is further provided on the horizontal guide rail.
[0010] On the basis of the above solution and as a preferred solution of the above solution: a vertical driving module for driving the second movable block and the third movable block to rise and fall synchronously is provided on the vertical guide rail.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] An inert gas injection ring is set on the outside of the welding gun. The inert gas injection ring can additionally spray inert gas toward the weld position, effectively isolating the air and preventing oxidation of the welding material. The inert gas sprayed by the inert gas injection ring converges toward the working position of the spray gun, which can increase the inert gas content at the weld per unit time, while ensuring welding quality and efficiency.
