Definitions

  • the invention relates to a tool grinding machine according to the preamble of claim 1.
  • Such tool grinding machines have basically been known for a long time and are used in particular for repairing cutting tools, i.e. for resharpening the cutting edges, the cutting geometry as such being to be restored if possible.
  • Cutting tools in the above sense should not only be understood to mean special tools with a special cutting geometry, but also standard tools in the form of milling cutters, drills or countersinks.
  • Such tool grinding machines are usually built on a machine stand which contains all the assemblies required for the function.
  • this includes the horizontally arranged worktop that is placed on the machine stand, which is usually manufactured with high precision and has fastening options, in particular in the form of grooves, for further assemblies.
  • a workpiece carrier is placed on the worktop, which holds the tool to be machined.
  • the workpiece pallet is equipped with a longitudinal and a transverse support, for example, which allow quick adjustment in both the longitudinal and transverse directions.
  • the workpiece spindle can be driven in rotation or by itself coupled to the longitudinal support, so that any desired combinations of a rotary and feed movement can be realized.
  • the tool is processed by means of a grinding tool, for example by means of a grinding wheel, which is interchangeably attached to a grinding head.
  • the grinding head can be adjusted in several axes so that the desired contour can be traversed.
  • the grinding head is mounted on a vertically arranged grinding column provided with a height adjustment, the grinding column itself being mounted on a turntable so as to be pivotable about a vertical axis.
  • the turntable is also placed on the worktop, adjacent to the workpiece carrier in such a way that the grinding wheel can be aligned with the workpiece.
  • Such a tool grinding machine, from which the invention is based has become known, for example, in the prospectus of Christen AG, Wabern-Bern, Switzerland "Christen Tool Grinding Machines, AU-150 Universal Tool Grinding Machine", pages 4-7.
  • the invention was therefore based on the problem of further developing a tool grinding machine of the type mentioned at the outset in such a way that it no longer has the disadvantages described.
  • a generic tool grinding machine should be implemented that is as compact as possible and allows unhindered access to the work area.
  • the invention is based on the idea of no longer placing the turntable with the grinding column attached to it on the worktop, but rather integrating it underneath in the machine stand. There is usually enough space below the worktop to accommodate the turntable without any problems.
  • the grinding column carrying it is attached to a support arm which is attached to the turntable on the one hand and is led out laterally from the machine stand in order to To be able to accommodate the grinding column.
  • the grinding column is mounted outside the worktop, which means that the work area is optimally accessible from all sides.
  • the machine stand can be made compact and space-saving, as a result of which a considerable cost advantage can be achieved compared to a comparable conventional design.
  • the unhindered accessibility of the work area results in ergonomic advantages, so that a faster workpiece and / or tool change is also possible. Furthermore, the turntable is not contaminated by abrasive particles or the like, since this is arranged below the worktop and thus protected from it.
  • the turntable is preferably mounted in two places, whereby a previously unknown stability can be achieved. Specifically, this is made possible by the fact that a bearing pin is provided which is guided centrally through the turntable and projects above and below it. Bearings are provided on the respective protruding bolt ends, which are supported within the machine stand and / or at the bottom of the worktop.
  • This type of storage increases the load capacity of the turntable considerably compared to the previously customary one-sided storage, which can increase the precision.
  • the grinding column be designed to be more stable and / or accommodate additional modules, such as motors for adjusting the height or inclination of the grinding head.
  • Rolling bearings are preferably used as bearings, in particular tapered roller bearings, which are capable of absorbing the loads occurring in the axial and radial directions while at the same time taking up very little space.
  • the grinding column - and thus the grinding head - can preferably be pivoted by a little more than 180 °, preferably by 190 °, so that even complex shaped cutting contours can be traversed.
  • an alignment mandrel is provided, which can be positioned on the worktop in a precisely defined position and coaxial to the axis of rotation of the turntable. This allows the grinding wheel to be positioned in the fulcrum with maximum precision.
  • the tool grinding machine has a machine stand 2 in a design known per se, which contains all components or component groups, including a coolant device 8 and a tool holder 6.
  • the machine stand 2 carries a worktop 10 which is arranged horizontally and provided with a high-precision and flat-ground surface.
  • the worktop 10 extends essentially completely over the entire length of the machine stand 2 and is designed symmetrically with respect to a longitudinally continuous groove 12.
  • the groove 12 is used to fasten a cross slide formed by a longitudinal support 22 and a transverse support 24, which receives a workpiece carrier 20.
  • the workpiece carrier 20 can thus be moved both in the longitudinal and in the transverse direction.
  • the workpiece carrier 20 receives a workpiece 200 to be machined, which can be a milling cutter, for example, the cutting edges of which have to be reground.
  • a grinding head 30 is provided, which is mounted on a grinding column 32 in a manner known per se for height adjustment.
  • the grinding column is arranged vertically at one end of a support arm 34.
  • the opposite end of the support arm 34 is rotatably coupled to a turntable 36, which is rotatably mounted below the worktop 10 in the machine stand 2 in the manner described in more detail below.
  • the grinding column 32 - and with it the grinding head 30 - can be pivoted about a vertical axis.
  • the arrangement of the turntable 36 is selected so that the axis of rotation intersects the axis of symmetry of the worktop 10 (vertically).
  • the grinding wheel 300 which can be attached to the grinding head 30, can thus be placed exactly in the center of rotation and aligned centrally with respect to the workpiece 200 to be machined. Starting from this central position, a pivoting movement that is symmetrical on both sides can be carried out, which in particular allows the machining of radii in the end region of the tools 200.
  • the length of the support arm 34 is dimensioned such that it projects so far beyond the machine stand that the described pivoting movement is possible without hindrance.
  • the machine stand 2 in the swivel range of the support arm 34 in the area of the worktop 10 is designed such that, starting from the described central position, the grinding head 30 or the grinding column 32 on both sides by a little more than 90 °, thus a little more than 180 ° overall, is pivotable.
  • the swivel range is 190 ° and thus allows optimum accessibility to the workpiece 200 to be machined.
  • the accessibility is further improved compared to previously known tool grinding machines in that the work area which extends below the workpiece 200 to the surface of the work surface 10 is completely undisturbed by any internals, so in principle it also allows processing from below.
  • adjustment and alignment work are particularly easy and thereby reduce machine downtimes.
  • the turntable 36 can be actuated via a handwheel 38.
  • a mechanism not shown here, allows exact positioning in the desired angular position, in which the turntable 36 can be fixed in a manner known per se via a clamping member 42 (FIG. 2).
  • the clamping member 42 is over a gag 40 easily actuated.
  • All of the movement sequences described above, including the adjustment movements, can be carried out not only manually, but also in a partially or fully automatically controlled manner.
  • motors are provided which, for example, bring about the pivoting movement of the turntable 36 or the height adjustment of the grinding head 30.
  • a gallows 5 is provided on the side of the machine stand 2, on which a control panel 4 for programming the control is attached.
  • a CNC machine can be implemented using simple, inexpensive modules.
  • FIG. 2 shows a preferred mounting of the turntable 36. It is a double bearing with the turntable on both sides, i.e. is supported above and below.
  • a shoulder-shaped bearing pin 50 is provided, which receives the turntable 36 including the support arm 34 in a rotationally fixed manner.
  • the bearing pin 50 projects above the support arm 34 and carries a tapered roller bearing 52 at the end.
  • the tapered roller bearing 52 is inserted into the worktop 10 on the opposite side.
  • a further tapered roller bearing 54 is attached below the turntable 36, which is supported opposite one another in the radial direction on a base plate 56 which is attached to the machine stand 2.
  • the tapered roller bearing 54 is held by an adjusting ring 58, which is placed axially on the base plate 56 from below and fixed with a screw 60.
  • the clamping member 42 is provided, which is attached to the base plate 56 by means of a screw 62 and acts on the bearing pin 50.
  • the actuation takes place in a manner known per se by the toggle 40 attached to the outside of the machine stand 2.
  • the adjustment mimicry with which a fine adjustment of the swivel angle is possible via the handwheel 38 is also not shown in more detail.
  • the sectional view in Figure 2 shows that the bearing pin 50 is arranged with its axis of rotation exactly in the cutting plane predetermined by the longitudinal axis of the worktop 10.
  • an alignment mandrel 70 is therefore inserted into the worktop 10, the position of which is specified with high precision and is used to align the grinding wheel 300.
