Abstract
A probe is an elongated tube with sensors positioned to match the cylinder bores with respect to number and distance apart and having radially projecting contact pins. When employed as intended, the probe rotates and slides back and forth in stationary bearings that are in turn accommodated in uprights in a stand. The probe extends through the bores of the work, which is precisely positioned between the uprights by the same bearings. A drive unit with a driveshaft in alignment with the probe and with motors that operate in conjunction with the latter to generate a translation and a rotation respectively is also mounted stationary in the stand independent of the aforesaid bearings. One end of the probe is coupled to the driveshaft such that it can neither rotate on nor slide axially along it by a universal joint that compensates within limits for angular error and radial shaft displacement.
