Full-automatic single-tube pin welding device

Abstract

The invention relates to a full-automatic single tube and pin welding machine which belongs to the technical field of welding, and the welding machine comprises a machine bed at a driving end, a machine bed at a driven end, a driving feeding mechanism, a welding operation machine, a driven feeding mechanism, an automatic charging mechanism and a welding host. The driving feeding mechanism and the driven feeding mechanism realize the horizontal feeding of a welded steel pipe along the longitudinal direction of the welding machine and the radial rotary feeding motion of the steel pipe, the welding operation machine is provided with a pneumatic welding fixture and two automatic stud welding guns, the pneumatic welding fixture realizes the holding and positioning of the steel pipe according to production tact in the welding process, and the horizontal distance between the two stud welding guns and the vertical distance between the automatic stud welding guns and the welded steel pipe are adjustable. The automatic charging mechanism realizes the automatic pin charging process. The welding machine has simple structure, the feeding motion of two degrees of freedom can be realized by a servo motor, the positioning precision is high, the clamping action of the welding fixture and the charging process are pneumatically controlled, and the operation is convenient. The welding machine can complete pin welding operation automatically or manually.

Description

technical field [0001] The invention relates to equipment in the field of welding technology, in particular to a fully automatic single-tube pin welding machine. Background technique [0002] Pin welding is a key process in the production process of boilers and pressure vessels. At present, the welding of pins mainly uses the welding host of the arc stud welding machine and the manual stud welding torch, which is done manually by workers. The advantage of this welding method is high flexibility, but the disadvantage is that the welding quality is unstable and cannot be used for mass welding production. [0003] In recent years, the welding technology of boilers and pressure vessels at home and abroad has made remarkable new developments. With the substantial improvement of the working parameters of boilers and pressure vessels and the continuous expansion of application fields, higher and higher requirements are put forward for welding technology. For example, the steel p...

Problems solved by technology

The stud welding machine can simultaneously complete the welding task of multiple studs on the I-beam, but because the longitudinal feed movement of the mobile trolley is manually operated, the positioning accuracy is not high, the production efficiency is low, and it can only be used for I-beams Stud welding on beams, not suitable for stud welding production tasks on other types of workpieces
