Abstract

The invention discloses a hand-held space complex curve welding track coordinate measuring instrument and a measuring method. The hand-held space complex curve welding track coordinate measuring instrument comprises a cylinder, a cone and a sphere, wherein three coordinate measuring units are fixed at the axis of the cylinder and are used for measuring the coordinate value of each point on a complex curve welding track. An operator holds the hand-held space complex curve welding track coordinate measuring instrument to perform virtual welding along the space complex curve welding track coordinate measuring instrument, and records the space coordinate of each point on the space complex curve welding track, a robot completes the processing process according to these coordinate planning processing tracks, and the efficiency of the robot during space complex curve welding can be improved.

Description

technical field [0001] The invention relates to the field of coordinate measurement, in particular to a hand-held space complex curve welding trajectory coordinate measuring instrument and a measuring method. Background technique [0002] Since the 1980s, industrial robots have been widely used in the manufacturing industry. The "teach-replay" industrial robot has been widely used in industrial production due to its simple operation, no need for an environment model, and the ability to correct errors caused by mechanical structures during teaching. In order to ensure the accuracy of the teaching trajectory, there must be enough teaching points, especially for space-complex curves, the planning time is long and the efficiency is very low. As a result, the "teaching-reproduction" industrial robot has difficulties in docking the processing task curve. It is difficult to process tasks with complex curves in space, and the teaching efficiency is low. For example, for the proces...
