Definitions

  • the present invention relates to a grinding machine for grinding workpieces, in particular cams, and a grinding wheel holder and a method for grinding cam sets.
  • Grinders of this type are eg from the brochure " CamGrind - production solutions for the grinding of camshafts "of the company Studer Schaudt GmbH, Stuttgart from October 2006 known.
  • the model "CamGrind S” has a grinding device, which consists of a large and a small grinding wheel and is designed especially for grinding camshafts. With the large grinding wheel, the cams are first pre-ground by means of high power and the bearing seats are machined, while the small grinding wheel is used for finish grinding of the cam shapes or also for grinding the bearing seats.
  • a workpiece holding device which has on one side a workpiece headstock, which sets the camshaft in the desired rotation about its longitudinal axis, and on the other side a tailstock, which ensures that the camshaft during the machining is always aligned and centered.
  • the grinding wheels or the corresponding grinding spindles are movable within the xz plane relative to the camshaft.
  • the axes or directions x and z are mentioned, they always mean the two axes which span the plane which forms the machine bed.
  • the z-axis extends parallel to the longitudinal extent of the workpiece, here e.g. the camshaft, and the x-axis as a perpendicular axis, which corresponds to a movement of a tool on the corresponding workpiece from the side to or away.
  • a direction perpendicular to the x and z axes is also referred to as the y axis or direction. It therefore runs perpendicular to the machine bed.
  • the grinding of the cams directly on the shaft is performed for the purpose of accuracy, so that the cams are formed exactly with respect to the shaft.
  • the grinding of single cams is being used more and more because the manufacturers of the camshafts now succeed in being able to fit the individual cams very precisely onto a shaft.
  • the exact grinding of the individual cams is done individually or as groups of several cams, which are usually processed on a workpiece holder, usually a mandrel in a grinding machine.
  • the object of the invention is to provide a grinding machine adapted to the workpiece of the individual cams and optimized, a grinding wheel holder and a method for grinding cam sets.
  • this object is achieved by a grinding machine for grinding workpieces, in particular cams, with a machine bed, at least one grinding spindle, two grinding wheel holders, on each of which at least one grinding wheel is arranged and which are arranged opposite to each other in their orientation and with their longitudinal axes parallel to each other and two workpiece holding devices, each having a workpiece headstock and a setter pole, which are arranged opposite to each other in their alignment and aligned with their longitudinal axes parallel to each other, each workpiece headstock and associated buttstock for interposing therebetween a separate workpiece holder to be ground with Workpieces are formed and preferably the pegs are arranged along the z-axis between the workpiece headstocks.
  • the formation of the workpiece holding device in the way that a single workpiece holder with the workpieces to be ground, in particular cams, can be arranged between a workpiece headstock and a setter, has the advantage that the setter used a smaller space than that in the known grinding machines for complete camshaft used tailstock has.
  • a setter a device that is also known as the bezel, instead of using a tailstock, results from the fact that the length of the workpiece holders used is significantly less than a complete camshaft.
  • the smaller space requirement of the setting stick means that the grinding spindle running parallel along the z-axis next to this setting stick can move closer to this setting stick along the x-axis. This also results in a greater flexibility in the use of the grinding wheels, which are arranged on the grinding spindle, the result. These now no longer have a certain minimum size, which was based on the fact that the grinding spindle just can not be brought very close to the camshaft, since the tailstock here was decisive for the smallest distance between the grinding spindle and camshaft.
  • the workpiece holder is preferably formed here by a mandrel. At this mandrel, the workpieces to be machined are arranged in order.
  • Another advantage of the present invention is the two separate workpiece holding devices, each of which can receive a workpiece holder.
  • the previously already machined workpieces with their workpiece holder can be removed from the workpiece holder at the other second workpiece holder and replaced by a workpiece holder with unprocessed workpieces.
  • the grinding machine can immediately continue the grinding process on the now newly clamped workpieces in the second workpiece holding device. As a result, non-productive times in which the grinding machine is not involved in grinding operations are reduced to a minimum.
  • Another advantage in this context is the alignment of the grinding wheel holders and the workpiece holding devices to each other.
  • the workpiece holder with the workpieces can be machined in parallel, preferably in a plane perpendicular to the x-z plane, can be arranged.
  • the workpiece holders in the workpiece holding apparatuses with the workpieces point essentially inwards, while the workpiece headstocks with the drives point outwards as viewed from there.
  • This allows the grinding wheels, e.g. be moved between the workpiece holders between the grinding operations back and forth, also have to overcome the shortest possible paths. As a result, the aforementioned non-productive times are significantly reduced again.
  • the grinding wheels are arranged on two grinding wheel holders, which in turn are also arranged opposite to each other and aligned parallel to each other.
  • This at least one grinding spindle is, as a result of the arrangements described above, arranged between the workpiece holding devices and along with the also between them arranged grinding wheel holders along the z-axis between the workpiece holding devices reciprocated to perform the corresponding grinding operations can.
  • the grinding machine on a single grinding spindle, wherein each one of the two grinding wheel holders is arranged on one side of the grinding spindle.
  • This embodiment has the advantage that only one grinding spindle for the two grinding wheel holders must be used with the grinding wheels. This reduces the space requirements of the drives for the grinding wheel holders in height and depth. Furthermore, the cost of materials in the construction of such a grinding machine is kept low.
  • the grinding machine on two separate grinding spindles, wherein each one of the two grinding wheel holders is arranged on each one of the two separate grinding spindles.
  • the use of two separate grinding spindles has the advantage that the automatic balancing of such grinding spindles compared to grinding spindles with two-sided tool connection is much easier and more complication-free to implement. This has a positive effect on the minimization of material wear and on the accuracy of the machined workpieces.
  • the two separate grinding spindles are arranged together on a carriage, which is arranged to be movable on the machine bed.
  • the arrangement of the grinding spindles on a common movable slide has the advantage that the release of the workpieces just processed and the alignment of the other grinding spindle to the workpieces to be machined by only one device to be controlled is realized. The control is thus summarized and simplified while reducing the number of possible sources of error.
  • the two workpiece holding devices are each arranged at different distances above the machine bed and the two grinding wheel holders each at different distances above the machine bed.
  • the advantage of this embodiment of the invention is that it is possible in this way, the processing of different workpieces in the two workpiece holding devices in two split up separate levels. These planes are parallel to the xz plane. This has the advantage over an arrangement within a common plane that the resulting space requirement of the entire grinding machine is minimized within the xz plane.
  • the two workpiece holding devices are each arranged at the same distance above the machine bed and the two grinding wheel holders each at the same distance above the machine bed.
  • This embodiment of the invention has the advantage that the space requirement of the entire resulting grinding machine is minimized in the direction of the height above the machine bed, ie perpendicular to the x-z plane. In this way, it is namely possible to arrange the two workpiece holding devices with the workpieces to be machined within one and the same plane, which runs parallel to the x-z plane.
  • the spindle axis is each a workpiece headstock with the spindle axis of a respective grinding spindle arranged in a plane which is substantially parallel to the plane defined by the x and z-axis plane.
  • substantially parallel is intended to include deviations of the two planes of up to 10 °, but preferably to mean exactly parallel.
  • At least three, in particular four or five grinding wheels are arranged on a grinding wheel holder.
  • a grinding wheel is preferably used for grinding a workpiece.
  • the radial distance from the spindle axis of the at least one grinding spindle to an outer edge of the spindle block of the grinding spindle is greater than or equal to the radius of the grinding wheels.
  • the grinding spindle Despite such a small size grinding wheel, it is possible for the grinding spindle to continue to maintain larger dimensions in accordance with this aspect of the present invention. This allows high performance of the grinding spindle as a result. Thus, despite a smaller size of the grinding wheel used, a corresponding processing speed of the workpieces to be ground can be maintained or achieved.
  • the grinding wheels each have a roof profile. This measure has the advantage that the burr formation at the front and rear edge of the workpieces, as seen along the z-axis, ie in the longitudinal direction of the workpiece holder, is prevented, or that burrs can be removed more easily.
  • roof profile is here to be understood in the cross section of a grinding wheel, which cuts the grinding wheel in a plane containing both its axis of rotation and a radius to be recognized depression in the abrasive material.
  • the course of this depression is such that seen from one edge of the grinding wheel parallel to the axis of rotation in the direction of the other edge of the grinding wheel in front and behind a larger radius of the grinding wheel than in an intermediate region, these areas connected by a steep transition are so that the resulting cross-sectional profile is reminiscent of the shape of a roof.
  • the present invention also relates to a grinding wheel holder.
  • Previously known grinding wheel holders or grinding wheels for simultaneously machining a plurality of workpieces consist of so-called segmented grinding wheels which consist of helically arranged diamond-shaped glued-on abrasive material platelets. Such grinding wheels are relatively expensive to manufacture and therefore expensive, which has a negative effect on the final price of the workpieces to be machined.
  • this object is achieved by a grinding wheel holder with a rod-shaped support member, a fastening device for attachment of the grinding wheel holder on a grinding spindle and at least three, in particular four or five grinding wheels, wherein the fastening device is arranged at one end of the rod-shaped support member, the grinding wheels on the grinding wheel holder from each other are spaced apart and a Grinding wheel for grinding of one of at least three, in particular four or five arranged on a holder workpieces is used.
  • the advantage of this aspect of the invention is that already existing grinding wheels can be used for the resulting grinding wheel element in the form of this grinding wheel holder with the individual grinding wheels, and thus no special production of a continuous wide grinding wheel is required. The production costs are thus drastically reduced, which also has a positive effect on the final costs of the workpieces to be machined.
  • the distance between two adjacent grinding wheels is smaller than the distance between two adjacent workpieces to be machined and the grinding wheels preferably have a roof profile.
  • This measure has the advantage that due to the larger distances between the workpieces to be machined relative to the grinding wheels, the grinding wheels can protrude correspondingly over the edge of the workpieces.
  • the grinding wheels can also be used for processing of incurred burr.
  • the grinding wheel holders are designed in accordance with the statements made above. This combination of grinding wheel supports on the previously described grinding machine permits effective and precise grinding of the workpieces to be ground.
  • Another object of the present invention is a method for grinding cam sets, each having at least three, in particular four or five cams, which are arranged on a workpiece holder and processed with a grinding machine according to the previous embodiments.
  • This method makes it possible to minimize the non-productive times between the effective grinding operations, which merely consists of aligning the grinding spindle from the first to the second (or vice versa) workpiece holding device.
  • the in the Fig. 1 to 4 illustrated grinding machine according to the invention is designated in its entirety by the reference numeral 10.
