Abstract:
A workpiece gaging system includes carriage structure for a gaging part, movable longitudinally and laterally, and a rotor to rotate that structure; also indicator means is operatively connected with the part to indicate the status of engagement, displacement, or need for displacement, of the gaging part relative to a surface or surfaces (such as pipe threads) to be gaged, as at multiple locations. Measurement encoding and signal processing means are also provided.
Abstract:
When connection pieces inserted in a container or a pipe (4) are replaced, it is necessary to know exactly, both for installation and production of the new connection piece, the actual inner contour of the container (4) in the region to be penetrated by the new connection piece. The invention concerns a measuring system for measuring this contour, the system comprising an arrangement (14) which can be secured in its position relative to the wall and accommodates a rotatably mounted shaft (18) which can be moved axially therein. A measuring probe (22) with a measuring tip (28) is pivotably disposed at the free end of the shaft (18). The measuring system further comprises a device (36) for measuring an axial displacement (F) of the shaft and a device (50) for detecting and displaying contact between the measuring tip (28) and the wall.
Abstract:
An apparatus for controlling a plurality of dimensions on mechanical parts of different types fabricated in series comprises an intermediate tooling associated to each type of part and carrying feelers coming in contact with the part at the locations where the dimensions have to be measured. In order to enable the simultaneous measurement of a plurality of both inner and outer dimensions, the output elements (8a-8d, 13a-13d) of the different motion transmitting mechanisms (7a-7d, 12a-12d) are placed on the different intermediate toolings (5, 10) in the same relative positions so that, when each intermediate tooling (5, 10) is mounted on the frame (4) of the apparatus, they are facing the individual associated sensors (2a-2d) and in contact with the moving elements (3a-3d) of the latter, so that the displacements of the various feelers (6a-6d, 11a-11d) of each intermediate tooling (5, 10) are simultaneously transmitted by the respective motion transmitting mechanisms (7a-7d) to the moving elements (3a-3d) of the various sensors (2a-2d).
Abstract:
Method and device for measuring the profile of a tooth, wherein a measuring sensor (5) senses the profile of a tooth during a measuring operation. The action line (E), as a geometrical point of all contact points between the measuring sensor (5) and the tooth profile is a non-linear line.
Abstract:
The device for handling a cylindrical part (2) is provided with means for measuring its diameter and particularly comprises two arms (3, 4) intended to grip said part. In at least one of said arms, a dihedron is formed, wherein the part (2) is susceptible to be engaged, and a length measuring sensor (8) is fitted on the ridge of the dihedron to determine the distance from the surface of the part to said ridge, said distance representing the diameter of the part.
Abstract:
The present invention relates to a method and apparatus for dimensionally sorting a group of received articles, like fruits and vegetables, and using the determined different sizes for differentiation during the subsequent processing and handling of the articles. Generally, the size and shape of each article is determined by the degree of deflection of one or more sensor heads (18, 24) located along a path the article is traversing. The determined size and shape is then used to direct the article during the subsequent processing and/or handling of the article.
Abstract:
A computer-controlled machine equipped with sensors (3) determines position and orientation of a workpiece, with respect to a model of the workpiece, which is stored in a data processing system (2) interfaced to the machine (3), by measuring coordinates of points on the surfaces of the workpiece and determining a transformation in which a sum of squared distances from the points of the corresponding surfaces of the model is minimized. The determined transformation is improved so as to satisfy the specified tolerances.
Abstract:
Apparatus for counterbalancing a vertically movable element of a machine includes an air cylinder (24) attached to the movable element on the axis of movement and having a small axial opening (30) at its upper end. A piston (28) located in the air cylinder is attached to a fixed machine element (14) by a nonelastic, flexible member (66) such as a thin, nylon-jacketed wire passing through the axial opening in the cylinder. Air under pressure (36) sufficient to counterbalance the weight of the movable element is supplied to the space between the piston and the axial opening in the cylinder. The flexible member (16) makes the counterbalancing assembly relatively insensitive to misalignment and vibration. Air is permitted to leak around the piston to reduce friction and to relieve pressure buildup during downward movement. In another embodiment, the air cylinder is attached to the fixed machine element.
Abstract:
Measuring sensors (4) having a small measuring stroke are secured on support (6). The position of measuring points of a workpiece (2) is transferred to a sensor through transfer rods (8). Said transfer rods are guided in an interchangeable support (10). For changing over to another workpiece, the support (10) is exchanged with the transfer rods (8). Thus, it is possible to obtain short change-over times for a high measuring rate so that the measuring method is appropriate to flexible manufacturing systems. Instead of providing one sensor for each transfer rod, it is also possible to displace a single sensor along a line and to transfer one after the other the positions of the points to be measured by means of the transfer rods.
