Device comprising a support (50) with a seat (51) housing a measuring cell (53) with a movable armset (54) having a feeler (61) adapted to contact the part to be checked. In order to reduce the overall dimensions of the device, while guaranteeing the seat sealing and the stiffness of the movable armset, the seat (51) is closed by a metal lamina (62) coupled to the support (50) and a resilient seal (64) coupled to the metal lamina (62) and the feeler (61).

Device comprising a support (21-23) with a seat (27, 27') housing a measuring cell (24, 24') having a feeler (6, 6') adapted to contact the part to be checked and with a strain gauge transducer (12-17) for detecting the feeler position. In order to obtain a device with very small overall dimensions and high accuracy and repeatability, the measuring cell (24, 24') comprises an integral element (1) having a support portion (2) fixed in the seat (27, 27'), a free portion (4, 4') carrying the feeler (6, 6') and an intermediate resiliently deformable portion (3, 3'), whereto there is fixed a strain gauge (13) of the transducer (12-17).

A measuring head comprises an integral member defining a support portion, a plurality of fulcrums and a corresponding plurality of movable arms carrying feelers. The fulcrums are aligned for defining a single axis of rotation for the movable arms. Position transducers electrically detect the positions of the movable arms. Two measuring heads are employed for realizing a snap gauge for simultaneously checking a plurality of diameters.

A reference master part for linear dimensions and/or geometrical and/or shape features of determined workpieces (30) comprises precision-machined surfaces having mutual spatial arrangements such as to provide known references for said dimensions, etc. For simplifying the manufacturing processes and reducing the costs, the master part is made of a support body (1; 31) of ordinary material, reference elements (7, 8; 41-46, 50, 51, 54-57, 63, 64, 70, 71), of special material for master parts, fixed in corresponding seats (4; 33-38, 58-60) of the support body, and supporting and guiding elements (63, 64, 70, 71), made of special material, fixed to the support body. During the master part manufacturing, the reference elements are adjusted and then fixed in the relevant seats.
摘要:
A snap gauge comprising support means; a substantially U-shaped integral member defining two movable arms carrying feelers for contacting a workpiece to be measured; transducer means coupled to the movable arms; and a Vee reference device for cooperating with a cylindrical surface of the workpiece. A rotatable pin couples the Vee reference device to the support means and permits adjustment of the position of the Vee reference device along a longitudinal direction. The gauge further comprises protective devices including a U-shaped element arranged internally with respect to the integral member, two protective elements coupled to radially bent ends of the U-shaped element, and two protective half-shells coupled to the support means.

A gauging head for checking linear dimensions of mechanical parts comprising a substantially cylindrical casing, a stem partially arranged for sliding movement within the casing, a feeler coupled to an end of the stem external with respect to the casing for touching the part, a transducer for providing a measurement signal and a cable for connecting the transducer to an external electric unit. An additional element can be removably and adjustably coupled to the casing for limiting the pre-stroke of the stem and another additional element can be removably coupled to the casing for defining the direction of exit of the cable from the gauging head.

The gauge includes two movable members carrying relevant feelers for contacting the bore surface of a piece for checking its internal diameter. The two movable members are obtained by making a longitudinal cut and a transversal bore in a single part. A resilient lamina is coupled to the movable members and a wire is connected between the lamina and the movable element of a transducer to transform the radial movements of the feelers into axial displacements of the transducer element.

A gauge including an outer tubular casing that houses a gauging armset having a movable arm with a feeler adapted to touch the piece to be checked. An element of the armset is clamped to a wall of the casing by means of rivets.The gauge can be fixed to a support by means of connection screws coupled to the rivets.

A drawer for electric cabinets including a frame, at least a removable front panel and a locking device for locking the panel to the frame. The locking device comprises two horizontal cross-members rotatable about axes defined by the frame and includes channel shaped parts to grip edges of the panel. Two handle blocks fixed to the frame have relevant handles, which may act as hinge elements for cooperating with other hinge elements fixed to the panel, in order to provide a temporary support and swinging device for the panel when it is removed from the frame.
摘要:
The apparatus includes a service module which receives measurement signals from gauging heads and amplifies them, through amplification circuits, at levels permitting a subsequent direct processing and operation modules connected to the service module through a multipolar flexible cable which include programmable matrices for selecting the signals necessary for the checking to be carried out by the relevant operation module. The apparatus is particularly adapted for processing signals relating to dimensional checking of mechanical parts.
