Definitions

  • the present invention relates to a device for machining indentations, for both regulation and retention, in a tube that forms part of the frame of a vehicle headrest.
  • This is the field of the present invention is that of machining means for making indentations, notches and the like in metallic tubes or structures.
  • the machining of retention and regulation indentations on the headrest tube has been made using grinding means, that is, by removing material, which causes cracks and perforations in the machining area, weakness in the tube structure and the need for a subsequent polishing to remove the usual burrs produced in the grinding process.
  • the device for machining indentations in headrest tubes comprises a support matrix that holds a tube in order to make indentations in it, positioned on a press that exerts a pressure on said matrix in a vertical direction such that the tube is rigidly secure in the support matrix.
  • the device has a roller holder in which can turn freely at least one form roller, connected by an arm to a vertical displacement mechanism formed by a motor, an eccentric piece and a connecting rod, mechanically linked such that the roller can move up and down.
  • a horizontal displacement mechanism for the support matrix consisting of a spindle coupled to the shaft of a motor, which allows the horizontal movement of the support matrix towards the roller holder.
  • the device as described above eliminates the polishing process for the tube surface after machining, as no burrs are generated. This means that the tube structure is not weakened, as no cracks or perforations occur in the machining area, favouring the subsequent coating process.
  • the present invention relates to a device for machining regulation indentations (2) and retention indentations (3) in a tube (1) that forms part of a frame for a vehicle headrest.
  • the device has a support matrix (4), which holds the tube (1) in which the retention (2) and regulation (3) indentations will be made.
  • the support matrix (4) is placed in a press (6), such as a hydraulic press, which exerts pressure on the same in a vertical direction, such that the tube (1) is rigidly secured in the support matrix (4).
  • horizontal direction is used to mean that parallel to the ground, which coincides with the table or bench (17) on which the device is set.
  • vertical direction is used to mean the direction perpendicular to the horizontal direction towards the ceiling.
  • the device includes a roller holder (5) that is connected to a vertical displacement mechanism formed by a motor (11), an eccentric piece (9) and a connecting rod (7) mechanically interconnected, with a rotation transmission that allows upward and downward movements of said roller holder (5).
  • the eccentric piece (9) is a cylindrical disc with a rotation axis displaced from its centre, to which the connecting rod (7) is hinged. In addition, said eccentric piece (9) is concentrically connected to the motor shaft (11).
  • the roller holder (5) is rigidly connected to an arm (14) that in turn is hinged to the connecting rod (7). Similarly, the roller holder (5) is mounted on a vertical guide (15), placed perpendicular to the motor shaft (11).
  • roller holder (5) turns freely at least one form roller (8), which has been made according to the geometry of the indentation to obtain.
  • the form roller (8) is in charge of making the regulation (2) or retention (3) indentations on the surface of the tube (1).
  • the support matrix (4) has a horizontal displacement mechanism formed by a spindle (12) joined with freedom to move to its rear face, which in turn is coupled to the shaft of a motor (10), such as a servomotor.
  • the horizontal displacement mechanism allows the movement of the press (6), in which the support matrix (4) is placed, towards the roller holder (5) on the guides (13) placed parallel to the longitudinal axis of the spindle (12).
  • the tube (1) is inserted in the support matrix (4).
  • a press (6) applying about 2700 Kg in a vertical direction exerts its force on the support matrix (4) that holds the tube (1) to be machined, preventing it from moving during the process.
  • the roller holder (5) has at least one roller (8) that turns freely, and initiates a rising and lowering process by means of its vertical displacement mechanism formed by the motor (11), the eccentric piece (9) and the connecting rod (7) coupled to its arm (14), and a horizontal displacement of the assembly formed by the support matrix (4) and the press (6) actuated by the spindle (12) that is coupled to the motor (10).
  • This enables a gradual copying of the shape of the roller (8) on the tube (1) being machined until the desired depth is achieved.
