Abstract
In a gripping or clamping device it is important to detect the position of the clamping jaws. In the prior art this is achieved by incremental or absolute measurements which, for example, carry out optical sampling of a measuring bevel. The present invention provides an approach that is less expensive and at the same time less susceptible to soiling, as well as space-saving. It is proposed to mount magnetic encoding on at least one clamping jaw and to evaluate this magnetic encoding by use of a magnetic sensor.
Claims10
A gripping or clamping device, comprising a housing (2) with a tensioning guide (8), and at least one clamping jaw (9, 10) that is movable in this tensioning guide (8), wherein a position sensor for detecting a position of the at least one clamping jaw (9, 10) is associated with the housing (2), characterized in that magnetic encoding (12) is associated with the at least one clamping jaw (9, 10), and has at least the length of a clamping stroke of the at least one clamping jaw (9, 10), and over this length has magnetically encoded markings that may be read out by means of a position sensor, in the form of a magnetic sensor (7), associated with the housing (2).
