Definitions

  • the invention relates to a method for grinding the main and stroke bearings of a crankshaft by external cylindrical grinding, and to an apparatus for carrying out the method.
  • the steel or cast iron crankshafts are produced in large quantities for internal combustion engines of motor vehicles. In addition to economical mass production, the greatest possible accuracy in terms of diameter, roundness, concentricity and centricity is important here. At grinding method of the type mentioned therefore very high demands are made. According to the EP 1 181 132 B1 It had already been recognized that the grinding result can be improved by grinding the main and crank bearings of the crankshafts in a specific order.
  • crankshaft With the pre-grinding of the main bearing was started in this known method, so that the crankshaft is clamped in a well-defined axis of rotation, namely its determining geometric longitudinal axis for the grinding of the stroke bearings.
  • This determining geometric longitudinal axis must be available as a reference axis for machining the stroke bearings.
  • all main bearings as well as other areas of the crankshaft concentrically arranged relative to the main bearings must be aligned exactly with respect to diameter, roundness, concentricity and centricity according to the determining geometric longitudinal axis of the crankshaft. The same applies to the center line of the crank pin, which in turn is determining geometric longitudinal axis for the rod bearings.
  • the existing geometric longitudinal axis is fixed by means of centering holes on the end faces of the crankshaft.
  • the crankshaft is clamped between tips at their center holes and driven by a driving device for rotation.
  • This type of clamping has the disadvantage that a certain axial pressure must be exerted on the crankshaft, whereby there is the danger of additional deformations, because the crankshaft bends under the effect of an axial pressure. Therefore, the attachment of one or more lunettes is required.
  • the invention is therefore based on the object of improving the known methods for grinding the main and stroke bearings of crankshafts in such a way that the accuracy of the grinding result is further improved while still being economical.
  • the inventive method for grinding the main and stroke bearings has the advantage that all stroke bearings of the crankshaft are ground by CNC-controlled external cylindrical grinding to the finished size already in the first stage of the process.
  • Experience shows that the strongest deformation of the crankshaft, which results from the release of stresses, thus takes place right at the beginning of the grinding. The stresses in the crankshaft have then completely degraded, and there is no further significant delay more. Only then will be started with the grinding of the main bearings, with the greatest possibility of correction exists.
  • the invention achieves this result in a surprising way by refraining from turning the crankshaft when grinding the stroke bearings around the determining geometric longitudinal axis.
  • this longitudinal axis is known and fixed by located on the front sides of the crankshaft center holes.
  • the crankshaft is clamped to two non-ground bearings, which are spaced apart in the common longitudinal extension the main camp lie. Clamping is achieved, for example, by tray chucks which comprise the two non-ground bearing points, in each case without exerting an axial pressure on the crankshaft.
  • These two bearing points define an actual axis of rotation whose deviation from the determining geometric longitudinal axis of the crankshaft is known by measurement.
  • the known deviation is taken into account when grinding the stroke bearings as a correction function in the computer of the CNC control of the grinding machine.
  • the finished ground crank bearings then have an exact relation to main bearings of the crankshaft, which would be sharply ground according to the determining geometric longitudinal axis of the crankshaft.
  • crankshaft clamping of the crankshaft is changed and made a second set-up, in which the crankshaft is clamped at its axial ends and driven to rotate about their determining geometric longitudinal axis; In this second setup, all main bearings are ground to the final dimension by external cylindrical grinding.
  • the blanks of the crankshaft are pre-machined by machining, then measured for the first clamping bearings in terms of diameter, roundness and centricity and from the deviation of the measured values of the determining geometric longitudinal axis a correction function for the pendulum stroke grinding method of the rod bearings educated.
  • a radially extending straight line originating from the determining geometric longitudinal axis is defined as the reference line for the angular position of the measured values and for this purpose a reference bore in a front side of the crankshaft is measured.
  • the two outer main bearings come into question or other end-side cylindrical sections that lie in the same common longitudinal extent as the main bearings.
  • the two possible bearing points of the crankshaft are advantageously mounted in shell chucks of a grinding machine and the crankshaft is thereby driven at its two ends for rotation.
  • the drives at the two ends of the crankshaft usually workpiece headstock and tailstock - driven exactly synchronized by the machine control.
  • the grinding of the rod bearings in the pendulum-stroke grinding process can be carried out with a single grinding wheel, which serves from pre-grinding to finish grinding and is used successively on the various crank bearings.
  • a pendulum-lift grinding process in which several grinding wheels are used simultaneously is particularly economical.
  • each stroke bearings the same phase with respect to the determining geometric longitudinal axis. Therefore, two stroke bearings can be ground simultaneously and with the same radial feed movement to the crankshaft.
  • the two inner stroke bearings and then - after axial moving apart of the two grinding wheels - the two outer stroke bearings are ground first.
  • the grinding of the main bearing can be carried out under CNC control in accordance with a further advantageous embodiment.
  • the grinding of the main bearing takes place in the second clamping of the crankshaft, in which this is advantageously clamped between centering tips and driven at least at their werk Georgiaspindstock-side end by driving and driving means for rotation.
  • the entrainment and drive devices are advantageously made of compensation chucks, the jaws automatically create the still unground grip and compensate for irregularities and deviations.
  • Compensating chucks are based on the effect of a pneumatic or hydraulic pressure medium and are known. Due to the interaction of the centering points with the centering bores located on the crankshaft, it is then guaranteed in each case that in the second clamping, the crankshaft rotates exactly about its determining geometric longitudinal axis.
  • crankshaft is clamped in the first stage of the process at two unground bearing points, which are at a distance from each other in the common longitudinal extension of the main bearings, without being clamped by centering.
  • shell clamping chuck achieves a rigid clamping of the crankshaft, without having to exert an axial pressure on it.
  • the cylindrical grinding of the main bearings in the second set-up is particularly economical with a multiple grinding wheel set, the grinding wheels are located on a common driven axle and have the same diameter. But it is also possible to carry out the second processing stage with a single grinding wheel, which is successively delivered to the individual main bearings.
  • crankshaft in the second stage of the process support can be provided by means of one or more steady rest.
  • the invention also relates to devices for carrying out the method according to the invention.
  • the method according to the invention is not bound by the fact that it has to be carried out in a specific device.
  • the delivered, only machined crankshaft blanks can be measured in a measuring station and then be brought by in-house transport to a first grinding machine in which the pendulum stroke loops of the lifting bearings takes place.
  • a first grinding machine in which the pendulum stroke loops of the lifting bearings takes place.
  • at another location may be another grinding machine, in which the finished only on the stroke bearings crankshaft is now ground at the main bearings.
  • a joint set-up of the measuring station and the first and second grinding stations In most cases, it will be more advantageous to have a joint set-up of the measuring station and the first and second grinding stations.
  • An apparatus for carrying out the method according to the invention is specified in claim 14.
  • a common grinding cell having first and second grinding stations economically enables the combining of drive, control, and cooling and transporting means which must be present at both required grinding stations.
  • the direct upstream of the measuring station is advantageous in this case.
  • the cylindrical grinding of the crankshaft is terminated at least at the diameters of main and crank bearings and no further grinding work has to be performed.
  • Conventional grinding wheels based on corundum and CBN can be used.
