Embodiment Construction

[0035] figure 2 A measuring machine 10 according to the invention is shown with a Delta robot structure 12 . Delta robot structure 12 (also abbreviated as Delta structure 12 ) includes a base plate 42 that supports a workpiece 50 during measurements. In the proposed embodiment the base plate 42 is located at the bottom of the structure for placement on a floor or table in a horizontal orientation. For greater accuracy, the base plate is advantageously provided with clamps (not shown) for securing the workpiece 50 . The three arms 16, 16', 16" of the Delta robotic structure 12 with intermediate joints 26, 26', 26" connect their first ends to the base plate 42 by means of first gimbal joints 24, 24', 24" The arms 16, 16', 16" connect their opposed second ends to the end effector 18 (also referred to as the movable platform 18) by means of a third joint 28, 28', 28", and by means of an actuator ( not shown) is controlled by the control and analysis unit 38. The mobile platfor...

Abstract

A coordinate measuring machine (10) based on a delta robot structure (12) comprising: a base plate (42); arms (16, 16', 16''); a movable platform (18) with a probe (4), and a control unit (38) for controlling the movement of the movable platform (18). The base plate (42) is configured for accommodating a first workpiece (50) and the probe (4) is arranged in / at / on the movable platform (18) in a way using the free inside space of the delta robot structure (12) between the arms (16, 16', 16'') as measuring volume.

Description

technical field [0001] The invention relates to a measuring machine, in particular to a coordinate measuring machine (CMM) or a visual measuring machine (VMM) based on a Delta robot structure. Background technique [0002] In a conventional 3D coordinate measuring machine, a probe head is supported for movement along three mutually perpendicular axes (X, Y and Z directions). Thereby, the probe head can be guided to any arbitrary point in the measurement volume of the CMM / VMM and an object can be measured with the measurement sensor (probe) carried by the probe head. [0003] For measuring surface vibrations, various measuring principles are known: one is based on the use of ultrasonic sensors / ultrasonic transducers (called ultrasonic probes), another based on the use of tactile sensors (also called tactile probes), and even another One principle is based on the use of optical sensors (also called optical probes or cameras). For measuring the surface of a target object, an ...
