Problems solved by technology

[0005] (1) For robot welding of small and medium pipes in a narrow space environment, due to the integrated structure of the fuselage, the overall size is large, which affects its use;
[0006] (2) The angle of the welding torch of the welding robot suitable for small and medium-sized pipelines cannot be adjusted, and it can only be used for butt welding of pipelines, not for welding of 60° fillet welds.

Embodiment Construction

[0034] Below in conjunction with accompanying drawing and embodiment example, the present invention will be further described:

[0035] A four-axis clip-type welding robot includes a fuselage 1 for fixing a pipe to be welded and a welding actuator 4 for welding the pipe to be welded. The welding actuator 4 is connected to the fuselage 1 .

[0036] In this example: if figure 1 As shown: the fuselage 1 includes a plurality of independent fuselage blocks 10, and a plurality of fuselage blocks 10 are selected to be connected to each other to form the fuselage 1. After the connection, the multiple fuselage blocks 10 can be relatively rotated to make the fuselage The inner diameter of 1 is adjustable, and it is formed into a shape at least partially matching the outer diameter of the pipe to be welded, and the fuselage block 10 can be clamped on the pipe to be welded by fixing them.

[0037] In this example: if Figure 2-4 As shown: the welding robot also includes a displacement a...

Abstract

The invention relates to a four-shaft clamping type welding robot. The robot comprises a robot body used for fixing a welded pipeline, and a welding execution mechanism used for welding the welded pipeline, the welding execution mechanism is connected to the robot body, the robot body comprises multiple independent robot body block pieces, the robot body block pieces are mutually connected to formthe robot body, after connection, the robot body block pieces can relatively rotate to enable the inner diameter of the robot body to be adjustable, and a shape with at least part matched with the outer diameter of the welded pipeline is defined and is fixed to the welded pipeline; the robot body is provided with the robot body block pieces, the robot body block pieces are connected together in areplaceable manner, after connection, bending is achieved, the block pieces can be more attached to the pipeline, automatic welding of small and medium pipelines under the small and narrow space environment can be met, the radial operation height of the welding robot is 55 mm to be minimum, the axial operation distance (on one side of the welding gun) of the welding robot is 10 mm to be minimum,and the axial operation distance (the clamping side) is 200 mm to be minimum.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a four-axis clamping welding robot. Background technique [0002] For the automatic welding of small and medium-sized pipes with an outer diameter of 25-300mm and a wall thickness of ≤30mm in a narrow space, not only does the welding robot need to have four basic functions during the welding process: walking, wire feeding, welding torch swing, and welding torch up and down position adjustment, namely It has a four-axis structure, that is, the walking axis, the wire feeding axis, the head swing axis and the head arc voltage tracking axis, and the welding robot is required to be small enough in size to complete pipe welding in limited space. [0003] At present, there are many welding robots suitable for welding small and medium-sized pipelines. However, the robot welding for small and medium-sized pipelines in a narrow space environment adopts an integrated structure, resulting i...
