Background

The laser tracker is a common tool for measuring large spatial dimensions, can track a spatially moving target and measure the spatial three-dimensional coordinates of the target in real time, has high precision, high efficiency, good adaptability and convenient operation, and is widely applied to assembly and measurement of large-dimension workpieces in various industries such as aerospace, automobiles, robots, medical equipment and the like. In assembly measurements, the need to position the target part for punching is usually encountered, i.e. the three-dimensional coordinates of a certain hole center are known, which are generally projections in a certain plane, the actual position of the point is found on the surface of the object, marked and punched. At present, there are two types of existing punching and positioning methods:

the first method is to drill a round hole in the center of a target seat (the target seat is used for placing a target ball, the target ball is used for receiving light for measurement), the center of the round hole is coincided with the center of the target seat, the center of the target seat is coincided with the center of the target ball placed on the target seat, when the target seat is continuously moved until a laser tracker operates a computer to display the coordinate value of the target, the center position is found, the point is marked through a marker pen, and then the hole is punched through punching equipment. However, in this method, the dots are likely to be off-center, which results in a large positioning error, and the target ball is likely to move when directly pressed against the target holder after being taken away.

The second method is to cut a fan-shaped area from the target base, the top point of the fan-shaped area is the center of a circle, the target base is moved until the target coordinate is reached, then the marking pen is used for marking along two edges of the fan-shaped area, and the intersection point of the two edges is the position of the center of a circle, namely the point to be positioned. However, the angle of the stroke line in this way directly affects the position of the intersection point of the two lines, resulting in a large positioning error, and the target holder is easy to move during the line drawing process, which takes a long time to draw the dot mark and is inefficient.
