Transportable measuring instrument for testing the positional accuracy of a program-controlled appliance arm
In order to be able to test the positional accuracy of the tool holding fixture (25) of an industrial robot at the place of use, there are provided a plurality of telescopic rods (5a, 6a-5f, 6f) which are pivoted at one end, preferably by means of permanent magnetic ball cups (3a-3f), to a baseplate...

Zusammenfassung: | In order to be able to test the positional accuracy of the tool holding fixture (25) of an industrial robot at the place of use, there are provided a plurality of telescopic rods (5a, 6a-5f, 6f) which are pivoted at one end, preferably by means of permanent magnetic ball cups (3a-3f), to a baseplate (21) and between telescopic halves of which there is inserted in each case a length measuring transmitter (10a-10f) which is connected to a central processor. Inductive, capacitive or optoelectronic displacement sensors, for example, serve as the length measuring transmitters. The other ends of the telescopic rods (5a, 6a-5f, 6f) are pivoted to an adaptor (24) mounted on the tool holding fixture (25) in such a way that there is a unique connection between the lengths of the telescopic rods (5a, 6a-5f, 6f) and the spatial position of the adaptor (24). |
