Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The laser welding accompanying fixture system with trajectory self-adaptation and force feedback control is invented. Through pressure feedback control, the pressure roller is pressed against the workpiece to be welded. When the robot performs automatic welding, it moves synchronously with the robot through the connecting mechanism.

[0021] like figure 1 As shown, the mechanical structure of the embodiment of the present invention includes:

Abstract

The invention discloses a track self-adaptation and force feedback control laser welding follow fixture system which comprises a pre-pressing follow fixture mechanism arranged in front of a laser welding gun, a pressing follow fixture mechanism arranged 2-3 mm on the side of the laser welding gun, a pressure detecting control mechanism and a middle connecting plate. The pre-pressing follow fixture mechanism and the pressing follow fixture mechanism are fixedly connected with a welding mechanical hand through the middle connecting plate, and the pressure detecting control mechanism completes pressure feedback control over the pre-pressing follow fixture mechanism. The track self-adaptation and force feedback control laser welding follow fixture system has the track self-adaptation capacity in the X-Y-axis rotating direction and the pressure feedback control capacity at a welding part, the fixture system can be suitable for various workpiece types, the machining requirements for a high-accuracy welding technology can be met, equipment cost is lowered, and the automatic level and the welding machining quality are improved.

Description

technical field [0001] The invention relates to a fixture device in the field of industrial processing, in particular to a laser welding accompanying fixture system with trajectory self-adaptation and force feedback control. Background technique [0002] The workpiece needs to be clamped during laser welding, especially for large-scale thin-plate workpieces that will be deformed during processing. Ordinary fixtures are difficult to meet the processing needs, and accompanying fixtures must be used: such as laser welding on the roof of a car. The traditional method is Put the roof workpiece on the pre-manufactured membrane, and perform continuous welding after the four corners are fixed by spot welding. This positioning and clamping scheme will make the thin-walled parts of the roof in the welding process due to the pre-clamping of the roof. Deformation occurs due to stress, which affects welding quality; at the same time, it is necessary to manufacture matching membranes for ...
