Portable integrated machine for opening tube connecting and saddle-shaped weld joint welding

Abstract

The invention relates to a portable integrated machine for opening tube connecting and saddle-shaped weld joint welding, mainly comprising a hanging bracket (1), a main shaft (2), a rotating disk (3), a welding head (4) and a pipe-expansion mechanism (5), wherein a magnetic base (112) is arranged at a support part of the hanging bracket (1); the rotating disk (3) mainly comprises a big gear wheel (32) fixedly connected with the main shaft (2) and a rotating motor (31) fixedly connected with an outer disk (34); a pinion (33) at an end part of the rotating motor (31) is meshed with the big gear wheel (32); a circular movement of the welding head (4) around the main shaft (2) can be realized through the rotating disk (3); and the rough and accurate positioning of a welding gun (46) can be realized through regulating mechanisms such as welding gun radial direction, height, pose, swing, clamping and the like so that the opening tube connecting and saddle-shaped weld joint welding are realized. According to the invention, the flexibility of a system is enhanced and the vector superposition of multidimensional movements can be accurately carried out so that the quality of a technical process is guaranteed; and the portable integrated machine has the advantages of simple and compact structure, low cost as well as simpleness and easiness in use, maintenance and repair.

Description

technical field [0001] The invention relates to a saddle-shaped drilling and welding equipment, in particular to a saddle-shaped drilling and welding integrated machine which can be used for multiple purposes. Background technique [0002] At present, for boilers, pressure vessels, steel pipes and other workpieces, special saddle-shaped pipes with larger diameters (commonly known as main pipes) and small diameter pipes (commonly known as branch pipes) with saddle-shaped grooves are cut, and pressure vessels and steel pipes are butt welded. The automatic bevel cutting machine or the saddle-shaped bevel automatic welding machine are respectively completed. Such equipment is generally bulky, complex in structure, and expensive. In addition to this kind of independent special equipment, there are also multi-purpose machines that can simultaneously complete small main pipe cutting and saddle-shaped groove welding, but such equipment generally uses the design of mechanical mechani...

Problems solved by technology

[0002] At present, for boilers, pressure vessels, steel pipes and other workpieces, special saddle-shaped pipes with larger diameters (commonly known as main pipes) and small diameter pipes (commonly known as branch pipes) with saddle-shaped grooves are cut, and pressure vessels and steel pipes are butt welded. Groove automatic cutting machine or saddle-shaped groove automatic welding machine are completed separately, such equipment is generally bulky, complex in structure, and expensive

In addition to this kind of independent special equipment, there are also multi-purpose machines that can simultaneously complete small main pipe cutting and saddle-shaped groove welding, but such equipment generally uses the design of mechanical mechanisms and parameter coordination to complete the formation of approximate saddle-shaped tracks. Not high, and the parameters are relatively complicated. When the diameter of the weldment needs to be adjusted when the equipment parameters need to be adjusted, the process is often complicated and the flexibility is poor.
