A system for checking the axial position of a bearing (30) inside an hole (31) of an E-block (29), preferably during the assembly of an HSA, comprises a reference system (3) that locates the E-block, a coupling element (17) that comes into contact with the bearing, a floating element (8) that, being connected to the coupling element, assumes the attitude of the bearing, two or more detection devices, for example optoelectronic, that cooperate with the floating element and detect at the same time, at checking areas are spaced apart from each other, quantities indicative of the position and, in case, of the attitude of the bearing with respect to the E-block, and a processing unit (50) for receiving and processing the detected quantities. A corresponding method for checking comprises the steps of locating E-block and bearing to mutually movable parts of the reference system, detecting at the same time, at least at two checking are spaced apart from each other, quantities indicative of the position and in case, of the attitude of the bearing with respect to the E-block, and processing the detected quantities. The invention relates also to an equipment and a method for assembling HSAs, that respectively employ the above-mentioned system and method for checking the mutual position and, in case, the attitude of the bearing with respect to the E-block. |

1. A checking system for checking mutual position of a second component of a workpiece relative to a first component of the workpiece, the first component being apt to define an axis, comprising:
a reference system apt to define a reference plane and a main axis perpendicular to the reference plane, and locate the first component of the workpiece so that the axis of the first component is aligned to the main axis; a detection system adapted to define at least a first checking area and a second checking area spaced apart from each other, and detect, at said at least first and second checking areas, quantities indicative of the mutual position of the second component of the workpiece relative to the first component of the workpiece; and a processing unit connected to the detection system, adapted to receive and process said quantities in order to find out information about said mutual position; wherein the detection system comprises at least a first detection device adapted to define the first checking area, and a second detection device adapted to define the second checking area, said at least first and second detection devices being intended to operate at the same time, each on the respective checking area, and cooperate with one of the second component of the workpiece and a specific component of the checking system, said specific component being adapted to be coupled to the second component. |
