Definitions

  • the present invention relates to a device for adjusting the position of the return pulley relative to the drive pulley of an abrasive belt machine.
  • an abrasive belt machine requires a driving pulley and a return pulley. It is compulsory to realize the parallelism of the axes of the two pulleys; on the other hand, the abrasive belts are not of perfect and constant geometry in operation; Finally, it is necessary to be able to easily replace the abrasive belt.
  • Means have already been proposed for positioning the axis of the deflection pulley with respect to the axis of the driving pulley at a determined constant distance as a function of the length of the abrasive belt, to ensure alignment of the two pulleys and to keep the abrasive belt under constant tension.
  • the means used in the machine according to the invention are very simple and safe to operate for a reduced size and allow easy replacement of the strip.
  • this machine is characterized in that the collar of a hollow support arm extending laterally is tightened on the axis of the drive pulley and on a transverse screw from which the rod of an actuator is articulated. end is secured to a sliding rail on a gallop ball fixed in the arm, rail constantly pushed towards the return pulley by the jack, and in that this rail ends in a fork between the arms of which is housed a plate pivotally mounted on an axis integral with the end of the fork and serving as a bearing for the axis of the return pulley.
  • a handle fixed on the support arm and articulated on the rail makes it possible to move the rail back against the action of the jack to relax the abrasive belt and allow its replacement.
  • a knurled screw with locknut is engaged in a stirrup fixed to the fork of the rail to allow an oscillation of the support plate of the axis of the return pulley around an axis fixed at the end of the fork, in order to laterally move the idler pulley and correctly align the axes of the drive pulley and the idler pulley.
  • a clamp 2 welded to one end of the support arm 3, in metal profile with rectangular section for example; this arm makes it possible to secure the axis 17 of the return pulley 15 with the motor axis 1 at a distance determined as a function of the length of the abrasive belt 27 mounted on the pulleys 15 and 26.
  • the rotation of this collar 2 allows to orient the assembly around the motor axis 1.
  • this arm 3 is anchored by a transverse bolt 4, the rod 28 of a gas spring 5, the end 29 of which is secured to a rail 8, with a U profile for example, by a screw 6.
  • the screws 4 and 6 serve as anchoring and articulation to the jack 5, the latter not being able to be used for guidance.
  • the rail 8 slides on a gallop ball 12 fixed in the arm 3 by two screws 11. It is constantly pushed towards the return pulley 15 by the jack 5.
  • This rail ends in a fork 30 between the arms of which is housed a plate 18 serving as a bearing for the axis 17 of the return pulley 15.
  • This plate 18 is pivotally mounted on an axis 31 secured to the end of the fork 30.
  • This plate 18 being constantly pushed by the sliding rail 8, the return pulley 15 is constantly in a position of longitudinal extension ensuring correct tensioning of the abrasive belt 27.
  • a handle 7 is articulated on an axis 9 of the arm 3 and has a hole 33 receiving the screw 10 engaged in the rail 8; by actuating the handle 7 in the opposite direction from the thrust of the jack 5, the axis 17 of the return pulley 15 is relieved.
  • a stirrup 13 fixed by screw 14 on the fork 30 receives a knurled screw 20 and a lock nut 19.
  • the plate 18 By actuating the screw 20, the plate 18 is rocked around its pivot axis 31, which allows lateral movement of the return pulley 15 with a view to correct alignment of the axes 1 and 17.
  • This simple and precise device keeps the abrasive belt under tension, without trial and error when adjusting the pulley axes, guiding in a determined plane, changing the belt by simple action on a handle and the parallelism of the pulley axes by means of a unique action on an easily accessible knurled screw.
  • One of the advantages of using a gas spring 5 to position the bearing 18 of the axis 17 of the deflection pulley 1 5 lies in its reliability and in that the force required to relax the strip 27 is constant and in the axis of the profile.
