Embodiment Construction

[0017] Attached below Figure 1 ~ Figure 4 A preferred embodiment of the present invention will be described in detail.

[0018] Such as figure 1 As shown, the centering posture adjustment part of the all-position welding robot in this embodiment is composed of a horizontal angle adjustment mechanism 1 and a vertical angle adjustment mechanism 2, and is mainly used for adjusting the posture of the welding torch 27.

[0019] Horizontal direction angle adjustment mechanism 1 can realize horizontal direction angle adjustment, and its specific structure is as follows: figure 2 As shown, it includes a first motor 11 , an end cover 12 , a base 13 , a first bearing 14 , a transmission shaft 15 and a rocker 16 . Wherein: the base 13 is connected with the welding robot arm, the end cover 12 is fixed on the base 13 by studs, and the first motor 11 is fixed on the end cover 12 by screws. The output shaft of the first motor 11 protrudes toward the rocker 16 through the base 13, and th...

Abstract

The invention discloses a welding equipment part, in particular to a centring gesture correcting member of a full-position welding robot. The system comprises a horizontal direction angle governor mechanism and a vertical direction angle governor mechanism, wherein the horizontal direction angle governor mechanism comprises a substrate, a first motor, a transmission shaft and a rocker, the transmission shaft is coaxially connected with the output shaft of the first motor, and the rocker is connected with a transmission shaft and swings along the horizontal plane when driven by the first motor; the vertical direction angle governor mechanism comprises a case installed on the rocker, a second motor, a gear installed on the output shaft of the motor, an incomplete gear ring installed on the bearing and a welding gun installed on the incomplete gear ring and can swing in the vertical plane when driven by the gear; the welding spot of the welding gun is positioned on the intersection of the rotating axis of the rocker and the rotating axis of the incomplete gear ring. The invention eliminates coupling among all parts of the welding robot while flexibly converting welding gun gesture and simplifies integral structure and size.

Description

technical field [0001] The invention relates to a component of welding equipment, in particular to a centering posture adjustment component of an automatic welding robot. In the case of narrow working space, this system can be applied to complete the closed welding of space intersecting lines such as pipe butt joint, large vessel head welding and vessel cannula welding. Background technique [0002] Welding is one of the most important fields of application of industrial robots, and welding robots are a frontier topic in the field of welding automation. Since the development of welding robots, the arm structure has been greatly improved. At present, the welding torch posture adjustment of industrial robots mainly depends on the adjustment of jointed arms and wrists, but this adjustment has the disadvantages of great coupling, cumbersome algorithms and complex structures. It is of great practical significance to study the centering attitude adjustment parts of all-position ...
