Abstract
The invention concerns a device for the precise positioning of a measurement probe along a probe axis A and which can rotate around this axis. By the coaxial arrangement of adjustment units for rotating and longitudinal displacement of the probe as well as by an rpm step-down gear arranged therebetween, a compact construction of the device is made possible and a coaxially situated passage is kept free, through which the probe shaft can be inserted and removed.
Claims16
Apparatus for linearly and angularly positioning a measurement probe, said apparatus comprising:
- a positioning device, said probe including a probe shaft extending through said positioning device and having an end to which a probe head is secured,
- said positioning device being substantially cylindrical and said probe shaft extending along an axis which is coaxial with said positioning device,
- a linear adjustment unit i n said positioning device for axially adjusting said probe shaft,
- an angular adjustment unit in said positioning device for angularly adjusting said probe shaft,
- said linear adjustment unit and said angular adjustment u;;nit being axially spaced from one another along said shaft,
- said linear adjustment unit and said angular adjustment unit respectively comprising hollow shaft motors coaxially surrounding said shaft, and
- means for transmitting angular movement to said shaft from the angular adjustment unit and axial movement to said shaft from the linear adjustment unit,
- said hollow shaft motors of said linear and angular adjustment units being concentrically arranged around said probe shaft and having central spaces through which said probe shaft extends coaxially therewith.
