Auxiliary teaching tool for non-contact welding robot

Abstract

The invention provides an auxiliary teaching tool for a non-contact welding robot. The auxiliary teaching tool comprises an auxiliary teaching accurate point-aligning tool, the auxiliary teaching accurate point-aligning tool comprises a sleeve I, a sleeve II and a sleeve III, a convex lens I is arranged at a front end opening of an inner cavity of the sleeve I, the sleeve II is sleeved with the rear part of the inner cavity of the sleeve I, a convex lens II is arranged at a front end opening of an inner cavity of the sleeve II, the front part of the sleeve III is sleeved with the rear part ofthe inner cavity of the sleeve II, a light source is arranged in an inner cavity of the sleeve III, axial movement is generated between the sleeve I and the sleeve II to adjust the distance between the convex lens I and the light source, and axial movement is generated between the sleeve III and the sleeve II to adjust the distance between the convex lens II and the light source; a positioning connection block is arranged at the rear end of the sleeve III, and the rear end of the positioning connection block is connected with a gun head of a welding gun through a fixing assembly to enable a light beam generated by the light source to be collinear with a welding wire in the welding gun. According to the auxiliary teaching tool, the light beam is aligned with a target point to achieve non-contact teaching, the teaching point-aligning efficiency of welding robot programming is improved, and accidents such as collision and interference in the teaching process are reduced.

Description

technical field [0001] The invention belongs to the technical field of positioning tools, and in particular relates to an auxiliary teaching tool for a non-contact welding robot. Background technique [0002] The programming methods of traditional welding robots are generally divided into two methods: online teaching and offline programming. The trajectory of offline programming often has a certain deviation from the actual trajectory, so both online teaching and offline programming usually involve manual teaching of welding target points. In order to make the welding gun welding wire of the welding robot aim at the target point more accurately, the contact thimble is generally used to touch the target point. This method has higher requirements on the operation level of the teaching staff, and collision accidents will occur if there is a slight carelessness. And it takes a long time to reduce work efficiency. Therefore it is necessary to propose improvements. Contents of...
