Definitions

  • the invention relates to a profile grinding unit with at least two tool holders fastened in a frame, to each of which a grinding tool for machining workpieces transported past the profile grinding unit in a working plane is fastened, the tool holders being arranged in different angular positions and their tools complementing each other to the desired profile shape (see for example DE-A-30 34 206).
  • the invention is therefore based on the object of designing a profile grinding unit of the type mentioned at the outset in such a way that a perfect grinding result is achieved with the use of a plurality of grinding tools while requiring little space.
  • the profile grinding unit according to the invention thus has an arrangement of the tools which enable the grinding process to be carried out in one gear, but do not have the disadvantages of the rigid shape of a one-piece tool.
  • the tools at an angle to each other can compensate for any thickness tolerance of the workpiece by a certain flexibility in the axial direction of their tool holder.
  • the belt guided in the direction of transport runs simultaneously over the several tools. In the overlapping area, the two tools alternately determine the grinding shape in an identical manner.
  • the tool holder can be fastened in the frame in different angular positions.
  • This can preferably be achieved in that the tool holders are fastened to a holder with a contact surface arranged perpendicular to the conveying plane and direction and can be detachably fastened to the holder in various angular positions.
  • the releasable fastening is very simple if the holder and / or the tool holder have a plurality of holes which are aligned with at least two holes of the tool holder or the holder for fastening the respective tool holder in different angular positions.
  • the tool is fastened to the tool holder with a connecting piece which can be pivoted in the direction of the angular position, wherein the connecting piece can also be translationally displaceable perpendicular to the longitudinal axis of the tool holder.
  • the connector can be used to make fine adjustments to the tools.
  • the design of the profile grinding unit according to the invention can also be realized with a rotating tool turret which has a plurality of tool holder sets, the tool holders being arranged in different angular positions in each tool holder set, so that their tools complement each other to the desired profile shape. This makes it possible to effectively switch toothed tools for different profile shapes by rotating the tool turret without the need for major conversion measures.
  • the tool turret can be rotated both about an axis of rotation lying in the direction of transport of the workpieces and about an axis of rotation arranged perpendicularly thereto.
  • Figure 1 shows a plan view of the effective sides of a workpiece 1 facing two tools 2, 3, which - as shown in Figure 2 - are at an angle to each other and overlap in a symmetrical to the conveying plane 4 overlap area 5 so that one in the Conveying plane 4 moving workpiece 1 in the overlap area 5 alternately abuts one and the other tool 2, 3.
  • the tool holders 7, 8 are both at an angle of 45 ° to the transport plane 4 and thus form an angle of 90 ° to one another.
  • the connecting pieces 5, 6 are arranged offset from the central axis of the tool holder towards the workpiece and thus free up the space for the inner ends of the base plates 9, 10.
  • the side edges of the tools 2 ', 3' are designed so beveled to the conveying plane 4 that the size of the base plates 9 ', 10' can be kept so small that they practically do not overlap at their inner ends . Accordingly, the connecting pieces 5 ', 6' can be formed symmetrically to the longitudinal axis of the tool holder 7, 8.
  • Figures 1 to 3 show that in the same place in the conveying direction of the complete grinding process for the rounded edge of the workpiece 1 is carried out, however, with two tools 2, 3 and 2 ', 3', which are at an angle of, for example, 90 ° to each other and thus thickness tolerances of the workpiece 1 due to a low mobility of the tool in the direction of the central axis of the tool holder 7, 8 can compensate.
  • the arrangement of the two tools 2, 3 and 2 ', 3' at an angle of 45 ° to the conveying plane 4 is expedient.
  • a different angular position can be more advantageous.
  • FIG. 4 therefore shows a holder 10 to which tool holders 7, 8 can be fastened in different angular positions.
  • the holder 10 has a sickle-like front attachment 11, which is provided with an arc-like arrangement of a plurality of holes 12.
  • the bracket 10 is fastened with a fastening flange 13 to a crossbar (not shown) of a frame of the profile grinding unit.
  • a bracket 10 ' is shown, the crescent-like approach 11' is much wider and has a plurality of holes 12 which form a crescent-like grid.
  • This bracket 10 'therefore allows a greater range of variation in the attachment of the tool holder 7, 8th
  • Figure 6 shows a tool holder 7 which is screwed to the brackets 10, 10 '.
  • the tool holder 7 has two lateral lugs 14, each carrying a hole 15, the spacing of which corresponds to the spacing of the holes 12 of the brackets 10, 10 ', as will be explained with reference to FIG. 9.
  • the side lugs 14 ', 14 ⁇ are designed so that one lug 14' carries three parallel holes 16 a aligned with the longitudinal axis of the tool holder 7 a, while the other side lug 14 'with an elongated hole 16 'is equipped, which extends perpendicular to the longitudinal axis of the tool holder 7 a. Due to the elongated hole 16 ', this tool holder 7 a can be easily attached in the hole pattern of the secure projection 11' of the bracket 10 'in different angular positions.
  • a large variation of the fastenings can be achieved with the tool holder 7 b, which is shown in Figure 8.
  • Rivets or similar can be replaced.
  • Figure 9 illustrates that the connecting pieces 5 ', 6' are preferably laterally displaceable relative to the associated tool holder 7, 8, that is perpendicular to its longitudinal axis, and are also tiltable to its longitudinal axis. This allows a fine adjustment of the tools 2 ', 3' to be achieved, so that an optimal adaptation to the edge of the workpiece 1 to be ground can be achieved.
  • Figure 9 illustrates that an extended in the transport direction grinding belt 18 is guided over the tools 2 ', 3', so that the tools 2 ', 3' for the grinding pressure in the desired shape are responsible, while the actual abrasive is present on the grinding belt 18.
  • the grinding belt 18 is essentially at the same time on the tools 2 ', 3', so that the advantages of a uniform grinding process, as is the case with a single tool, set.
