Automatic welding device of character welding machine

Abstract

The invention discloses an automatic welding device of a character welding machine. The automatic welding device of the character welding machine comprises a character welding machine main body, a welding gun and a support frame, wherein the character welding machine main body comprises a main body upper part and a main body lower part; the character welding machine main body and a rotation motor are arranged on the support frame; the rotation motor is connected to the main body lower part, and connected with the main body upper part and used for driving the rotation of the main body upper part; a welding gun fixing adjustment seat and a welding gun forward-backward drive motor are provided; a welding gun movement guide rail horizontally penetrates in the main body upper part; a welding gun movement slide block is arranged on the welding gun movement guide rail; the welding gun forward-backward drive motor is connected with the welding gun movement slide block and used for driving the forward-backward movement of the welding gun movement slide block in a horizontal direction; the main body upper part is provided with a welding port, a sensor and a welding gun forward-backward movement limit switch; the main body lower part is provided with a welding gun rotation limit switch; an inverted-U-shaped welding port protection porcelain mouth is arranged at the welding port; and a location column used for locating a welded object is arranged at the welding port and at the front end of the welding gun. The automatic welding device of the character welding machine, which is disclosed by the invention, is simple in structure, capable of realizing the forward-backward movement of the welding gun along the direction of the movement guide rail, and the 360-degree horizontal rotation of the welding gun, long in service life, and high in welding efficiency.

Description

technical field [0001] The invention relates to a letter welding equipment accessory for advertising, in particular to an automatic welding device for a letter welding machine. Background technique [0002] Argon arc welding is a welding method that uses argon, helium or a mixture of the two as a shielding gas. It is widely used in many fields. At present, argon arc welding plays an important role in the welding application of advertising metal characters. However, in the prior art, manual welding is generally used for the welding of advertising metal characters. Manual welding has low welding efficiency, high requirements for welders’ skills, and high welding strong light radiation. At the same time, the toxic fumes produced by welding are due to manual welding. The welding points will change constantly, and it is impossible to install the exhaust gas device, which seriously affects the work efficiency and causes great harm to the staff. Therefore, the applicant applied for...

[0002] Argon arc welding is a welding method that uses argon, helium or a mixture of the two as a shielding gas. It is widely used in many fields. At present, argon arc welding plays an important role in the welding application of advertising metal characters. However, in the prior art, manual welding is generally used for the welding of advertising metal characters. Manual welding has low welding efficiency, high requirements for welders’ skills, and high welding strong light radiation. At the same time, the toxic fumes produced by welding are due to manual welding. The welding points will change constantly, and it is impossible to install the exhaust gas device, which seriously affects the work efficiency and causes great harm to the staff. Therefore, the applicant applied for a patent in 2013. The patent number is: ZL201320382968.6 The multifunctional letter welding machine solves the above defects. However, the applicant discovered the technical solution of the above patent during use. The letter welding machine can only rotate when welding letters. There are defects on the surface that need to be controlled manually, and the requirements for the welding operator are high, and the front and rear distance between the welding torch and the object to be welded cannot be well controlled, resulting in imperfect welding quality and efficiency, and when using welding, Due to the high temperature, long-term use will easily lead to shortened service life of the welding device
