Abstract:
A device (1) for measuring a valve seat formed in a piece has an elongate shape and defines a longitudinal axis (A), and includes: a slide (9), slidingly coupled to a guide (11) for translating in a scanning direction (B) inclined to the longitudinal axis; a sensor (10), mounted on the slide for measuring a parameter relating to a profile of the seat; a processing unit connected to the sensor; a rotary actuator (13) defining a longitudinal rotation axis substantially parallel to the longitudinal axis of the device; and a transmission assembly interposed between the rotary actuator and the slide for transforming a rotary motion about a longitudinal rotation axis in a reciprocating linear motion of the slide along the scanning direction.
Abstract:
This invention concerns a method and apparatus for measuring a part 4 with a contact probe 3 mounted on a coordinate positioning machine 1. The method comprises measuring a plurality of points PC on the part 4 when both the part 3 and contact probe 3 are moving continuously between different positions within the coordinate positioning machine 1.The probe 3 moves, relative to the part 4, along a scan path 20 such that substantially coincident points that are closely located together along a curve or surface being measured are measured at relatively far apart positions in the machine 1 and at relatively far apart positions along the scan path SC.
Abstract:
A circumference measuring gauge for measuring an item is shown and described. The circumference measuring gauge may include a base, a fixture displaceably positioned on the base, the fixture capable of securing the item, and a measuring member having first and second ends, the first end fixed to the base and the second end fixed to the fixture, where the measuring member circumscribes the item. The circumference measuring gauge may also include a biasing member secured to the fixture, wherein the biasing member applies a predetermined force to the measuring member.
Abstract:
The invention applies to a system for the measurement of the deviations from form and position of the surfaces and axes of rotational work-pieces towards a virtual primary datum, which contains datums (vee-blocks, centers, body's own bush bearings) to support the measured part, measuring heads for the measurement of the radial run-out in n cross - sections of the surfaces of revolution of the work -piece and two devices for the measurement of the wandering run-out into two cross - sections of the work-piece marked in advance, on the basis of which wandering run-out corrections are made of the measurement results of the radial run-out in all measured cross - sections and the deviations from form and position are calculated on the basis of the corrected results. The device for the measurement of the wandering radial run-out contains a multi-stage self - aligning prism and a plurality of measuring heads appropriately located in the line of measurement.
Abstract:
The invention relates to a measuring apparatus for cylinders, rolls and similar elements to be measured during the grinding operation, equipped with detection systems of the geometrical and dimensional characteristics (for example roundness, shape, diameter, etc.) and /or structural characteristics (for example, the presence of cracks and work hardening, measurement of the hardness, etc.) and/or surface characteristics (for example roughness, states of surface tension, etc. ) The measurement of the geometrical characteristicsis performed with four detection points .
