Abstract: Device having removable probe system and a stylus instrument. The probe system is connected to the stylus instrument in a zero position by the attractive force of the permanent magnet. A mechanical lever system is provided, which comprises a spring and, when the probe system is pulled out, transfers the probe system together with a part of the stylus instrument from the zero position into a replacing position through a displacement motion. At the same time, the permanent magnet is spatially separated from the probe system and the attractive force which acts between the probe system and the stylus instrument is reduced.

Abstract: Device with a removable probe head (15) for measuring a workpiece, whereby the device comprises a receiving section (17.1) for attaching the probe head (15). In the receiving section (17.1) sensors (17.2) in fixed, predefined positions are arranged. The removable probe head (15) comprises several counterpart elements, which interact with the sensors (17.2) if the probe head (15) is attached to the receiving section (17.1), whereby a coding of the removable probe head (15) can be set in advance, by adjusting the position of the counterpart elements.

Abstract: Described is a device for machine tools or measuring apparatus for detecting the spatial position of a carriage movable in a coordinate axis along a guide with respect to a reference standard which is designed as a rectangular plate extending parallel to the guide of the carriage. Two opposed, parallel surfaces of the reference standard carry each a two-dimensional line grating. A position measuring system serves the function of determining continuously the spatial position of a support member fixedly connectible with the carriage. The position measuring system includes three optical incremental reading heads and one distance sensor. The support member is arranged on the movable carriage such as to prevent the support member from contacting the reference standard over the entire length of the travel while at the same time detection is being performed.

Abstract: A device for measuring a rotationally symmetric precision part, having a dog, drivable via a drive, and a revolving centering means, the dog and the revolving centering means being positioned in such a way that a rotationally symmetric precision part to be measured may be non-positively clamped coaxially between dog and centering means. A first angle measuring system is assigned to the dog, which provides signals that permit the drive-side angular position of the dog to be stated, and a further angle measuring system is assigned to the revolving centering means, which provides signals that permit the output-side angular position of the centering means to be stated. Software means are provided which determine slip between the dog and the rotationally symmetric precision part through a comparative calculation on the basis of the drive-side angular position and the output-side angular position.

Abstract: The invention is directed to a device for direct detection of the spatial position of a probe element in a multi-coordinate measuring apparatus, with a reference system comprised of at least one first standard and one second standard that are associated with coordinate axes of the measuring apparatus. The first standard is a planar standard with a line grating array. The second standard is non-contacting relative to the first standard and movable in two dimensions by means of a cross slide. Provision is made for a first position measuring system for determining the spatial position of the second standard with respect to the first standard, and for a second position measuring system for determining the spatial position of a carriage carrying a three-dimensional probe assembly, with respect to the second standard. The device forms in an associated multi-coordinate measuring apparatus a continuous measuring chain from the first standard to the tip of the probe element.

Abstract: A device aids the setter of a cutter head for cutting, e.g., milling or hobbing, of spiral bevel gears to align all rod-shaped blades with their tip cutting edges to an axial height which is as uniform as possible and to move them with their profile cutting edges to a correct radial position in the cutter head so that uniform chip removal can take place. The device has a stable arm which can be moved numerically controlled axially and radially to the cutter head, with positions which are continuously measured and with which each individual blade can be automatically pushed into its chamber in the cutter head. A probe which is connected to the arm measures the axial height of the tip cutting edge of each blade before, during and shortly after each blade is pushed in.

Abstract: A scanning head for completely measuring gears and gearlike workpieces on numerically controlled measuring instruments must also posses 3-D properties for scanning unknown contours. To that end, the scanning pin or probe must deflect of its own accord in the currently prevailing direction normal to the contour being scanned. Only those scanning heads, whose behavior is statically and dynamically the same in all arbitrary deflection directions, can do this. The new scanning head achieves this by providing, for the three spatial coordinates X, Y, Z, two leaf spring parallelograms (1, 2) attached one behind the other to the stationary scanning head base (4). The first parallelogram (1), which is pivotable about the horizontal axis, permits deflections of the scanning pin carrier (3) in the XZ plane and the second parallelogram (2) permits deflections in the Y direction.

Abstract: The scanning head according to the invention has the horizontal main axis (1) and is provided for numerically controlled gear measuring devices. Its feeler (2) is guided by a linear slide (4) and the latter is guided by a leaf spring parallelogram (11, 12, 13, 14) in the two coordinate directions (6) and (16). Mechanical devices (8) and (18) hold the feeler in a definite central position from which it can be deflected with the same measuring force in both the positive and negative coordinate directions. A centrally located two-dimensional ruled grating scale (10) detects all deflections of the feeler in the plane spanned by the two coordinates. To adjust the third coordinate direction, a pivot mechanism (3) is used, with a roller bearing (2) being provided for weight balance for the leaf spring parallelogram, the outer ring of the bearing being suspended by at least two springs (21, 22) on a fixed part (23) above the scanning head.
