Abstract:
Portable robot for carrying out the drilling process in the assembly of aeronautical components which are secured on a support known as a stand. The robot comprises a displaceable platform in order to permit it to be located close to the stand, and an arm, which supports a frame comprising a beam intended to support a drilling head that can be displaced in the three axes.
Abstract:
The system comprises a headstock (1) in which is established a rotary shaft (10) driven via a cone (8) that can be coupled to a drive means, for example a robot, the shaft (10) being linked to a spring (11) which permits axial displacement of the shaft (10) in the upward and downward direction, while coupled to the other end, with the interposition of an eccentric (21), is a plate (2) for carrying an abrasive disc (3) intended for sanding the pins of the fasteners, following the operation of shaving said pins. The eccentric (21) transforms the rotation of the shaft (10) into an orbital motion so that, in combination with the upward and downward displacements by means of the spring (11), the abrasive disc (3) is successfully adapted on the surface on which the pin of the fasteners intended to sand is located.
Abstract:
It comprises a nozzle (4) with an inlet (5) for introducing of a rivet's (2) extra stem (1); and in front of which a milling tool (6) is included to trim the stem (1) of the different rivets made on a piece. The milling tool is anchored by means of a trimming compensation spring (11), and the nozzle (4) is fixed with a separation height with respect to the milling tool (6) which is the same as the trimming height, in such a way that the inlet (5) determines a mechanical trimming depth limit when contacting the rivet (2) head surface (17). The nozzle (4) is adjustable in height in order to select the trimming height, being adaptable to the different rivets existing in the market.It comprises an electrical limit (16, 14) from which, after the mechanical limit has occurred, the retreat of the head of the rivet in order to allow making a new rivet,
Abstract:
The device comprises a robot (1) provided with a head (3) which comprises a plurality of single-function modules, each of them with the function of carrying out different and consecutive operations on the working zone of the pieces to rivet or fasten. The robot can be a precise articulated robot, a Cartesian machine, a parallel kinematics robot or other, while said modules can be located transversally, longitudinally or in a matrix in the head. The method provides operations for drilling, reaming and countersinking of different diameters, quality control of drill-holes, thickness checking of pieces, application of sealant, selection and supply of rivet, fastener or pin to rivet or fasten, fitting of the rivet, fastener or pin, riveting and/or fastening, fitting checking of the rivet, fastener or pin, cleaning, adjustment and checking of the aerodynamic tolerance.
Abstract:
A countersinking-carrier nozzle has a flat front surface with a central hole via which emerges a countersinking drill, such that said flat front surface establishes a limit to the penetration depth of the countersinking nozzle. The nozzle includes a flexible retainer for the nozzle front surface so that it swivels when making contact with a curved countersinking surface, adapting itself tangentially to it while the headstock presses against the countersinking surface. The flexible retainer is defined by a ball-and-socket joint including a curvo-concave retaining receptacle, with the possibility of swivelling, with a complementary curvo-convex portion provided in the rear part of the flat front surface. This portion projects with respect to the receptacle to allow it to swivel when pressed against the countersinking surface, at which moment the complementary curvo-convex portion of the rear part of the front surface swivels in the receptacle of the headstock.
