Flexible circumference welding machine

Abstract

The invention provides a flexible circumference welding machine. The flexible circumference welding machine comprises a base, a workbench, a welding module, a driving module and a control module, wherein the welding module is used for welding an object to be welded on the workbench, the driving module can drive the welding module to move on a set track, and the control module is used for controlling moving of the driving module on the set track. The driving module comprises a linear moving module and a curve moving module. The curve moving module comprises a swinging module, a rotation module and a circumference module, wherein the swinging module makes a welding hand swing, the rotation module makes the welding hand rotate along an axis, and the circumference module makes the welding hand move vertical to a circumference. According to the flexible circumference welding machine with the technical scheme, circumference welding with complex situations can be achieved, wherein the circumference welding includes welding when components are fixed and the welding hand rotates, multi-circumference welding, one-time welding of circumferences with different heights, spiral welding, welding at arbitrary angles and the like. The problem that in previous circumferential movement, a power circuit is interfered with a rotation shaft is solved. The flexible circumference welding machine has the advantages of being simple in structure, low in machining cost, strong in adaptability, wide in application range and the like.

Description

technical field [0001] The invention belongs to the field of welding, in particular to a flexible circumferential welding machine. Background technique [0002] In the welding industry, the welding method mainly used for circumferential welding is to fix the welding hand and rotate the welded parts for welding. However, this method has certain limitations. When encountering the following situations, the existing circular automatic welding method is more difficult: [0003] 1. The components are too large, so the rotation radius of the components is large, the equipment cost is too high, and it is not easy to operate; [0004] 2. There are multiple circles in the part that need to be welded, and the rotation of the part cannot be realized, and only one circle can be welded; [0005] 3. There are multiple circumferences with different heights to be welded in one circumference welding, which cannot be realized by the existing circumference welding method. Contents of the in...
