Definitions

  • the present invention relates to a device for deburring and countersinking bores, with a housing and a drive element and an arm carrying a deburring and countersinking tool and with a toothed belt for driving the tool.
  • the invention therefore aims at providing a Vor ⁇ direction which U * possible in a simple manner a change --- nd adjustment of the arm length, and thus dar ⁇ provides a more suitable for the practical apparatus, since it is more universally usable.
  • FIG. 1 is a perspective view of the device in the assembled, ready-to-use state
  • Fig. 2 shows the device of FIG. 1 in a disassembled state.
  • the device 1 shown in the figures has a compact housing 3 with a small cover 4, which is connected to the housing 3 by means of screws 5 via screw holes 6 in the housing 3.
  • the 0 cover 4 partially covers a bottom 8 of the housing. This leads to an interior 9.
  • a larger bore 10 extends into the area of the counter wall of the base 8 to the housing 3, a side channel 11 corresponding to 5 opening into the bore 10 from the outside, as is the case with this 2 can be seen.
  • a ball bearing 13 is pressed into the housing wall opposite the bottom 8.
  • a drive shaft 14 with a collar 15 and a toothed belt pinion 16 is provided with a further collar 17 and a shaft end 18 (FIG. 2).
  • This drive shaft 14 is inserted into the bore 10 and the ball bearing 13 and protrudes from the housing 3 in the assembled state, as indicated by dash-dotted lines in FIG. 2.
  • the diameter of the bore corresponds to the outer diameter of the toothed belt pinion 16. Die.
  • the drive shaft 14 is supported at one end in the ball bearing 13 and with the shaft end 18 in one
  • Ball bearing 20 which is pressed into the cover 4.
  • a toothed belt 21 is used for driving.
  • a retaining pin 22 is fastened in the housing 3 and protrudes into the side channel 11.
  • a tool support arm 27 with a transversely continuous cutout 28 has a central bore for receiving a tension spring 29, which is designed as a helical spring.
  • Two side screws 30 hold the tension spring 29 in the support arm 27.
  • the thickened end of the support arm 27 is provided with guide rails 31 which fit into guide grooves 33 in the housing 3 and enable the two parts 3 and 27 to be connected to one another by insertion.
  • Belt guide channels 35 and 36 are provided on opposite sides of the support arm 27, at the end of which the support arm 27 is fork-shaped and serves to receive a toothed belt pinion 37. This is rotatable in two ball bearings 38 and 39 in the
  • a grub screw 43 is used to hold a deburring tool 45, which can thus be replaced in a simple manner.
  • the deburring tool 45 is provided with an actual tool head 46, which is followed by a bearing stub 47 with an end 48 which fits into a ball bearing 38.
  • a chamfer 49 in the bearing stub 47 enables the tool 45 to be held in a rotationally fixed and axial manner in the toothed belt pinion 37 and the ball bearings 38 and 39.
  • This device is installed in such a way that the drive shaft 14 is inserted into the housing 3 through the bore 10.
  • the toothed belt 21 is pushed laterally over the pinion 16 so that it extends along the side walls of the side channel 11 and protrudes therefrom.
  • the cover 4 is placed so that the shaft end 18 is supported in the ball bearing 20.
  • the cover is fastened to the housing 3 by means of the screws 5.
  • the tool support arm 27, which is available in different lengths, is inserted with its guide rails 31 into the guide grooves 33 of the housing 3 until the tension spring 29 comes to rest on the retaining pin 22.
  • a strap 21 of corresponding length belongs to each support arm.
  • Each device includes a set of tool support arms 27 of different lengths, which are interchangeably fastened in the housing 3.
  • the cover 4 has to be lifted away, the belt 21 has to be replaced by the corresponding belt for the new support arm 27 to be inserted, the cover has to be replaced and the new support arm has to be pushed in as explained.
  • the grub screw 43 is loosened, the deburring tool 45 is pulled out to the side and the other tool is pushed in, so that when the grub screw 43 is tightened, it meets the milling 49 of the bearing stub 47 and the tool firmly connected to the pinion 37.
  • This device is very compact, extremely simple in construction and easily adaptable to the problems which arise in practice with regard to the diameter of the bores, the location of the bores and the like.
  • the use of a toothed belt with a belt tension determined by a tension spring also represents an overload protection, in that the toothed belt is designed in terms of dimensions and material in such a way that when a predetermined circumferential force on the belt is exceeded, its teeth are elastically deformed, thereby driving the toothed pinion 37 is interrupted with the tool.
  • the critical circumferential force can be changed by the choice of the tension spring 29.

Abstract

Dispositif pour ébarber est chanfreiner des alésages (intérieur et extérieur), doté d'un boîtier et d'un arbre moteur dépassant de celui-ci, ainsi que d'un bras portant un outil pour ébarber et chanfreiner et d'une courroie dentée pour entraîner l'outil, rendant aisée et possible une modification et une adaptation de la longueur du bras, et donc d'un usage universel. Ce dispositif a pour caractéristique que le bras (27) est maintenu de façon amovible dans le boîtier (3) grâce à des gorges (33) et à des rails (31) et qu'il est sous pression de ressort (29), cette pression de ressort tendant la courroie dentée (21). Un jeu de bras (27) de différentes longueurs avec courroies dentées correspondantes (21) est prévu. On peut aussi changer d'outil (45). Ce dernier est un élément d'un jeu de changement d'outils.
