Definitions
- the present invention relates to the field of machining and in particular to adaptations making it possible to ensure complete machining of a crankshaft under the best possible conditions.
- DESCRIPTION OF THE PRIOR ART Crankshafts are mechanical parts in the form of shafts which ensure the transformation of the reciprocating rectilinear movement of the piston-connecting rod assembly of a heat engine into rotary movement. These parts are conventionally produced by forging or molding before being precisely machined.
- the crankshaft has five bearings by means of which it is in pivot connection with the casing, four crank pins arranged parallel to the axis of rotation of the crankshaft and serving to drive the four connecting rods and four counterweights ensuring a balance of the masses of the crankshaft relative to its axis of rotation with the four crank pins and the eight arms which offset them from the axis of rotation of the crankshaft.
- the start of the production chain by removing material from a crankshaft comprises the following operations:
- the machining process of the invention is remarkable in that it consists in carrying out the operations of dynamic measurement of the masses and removal of material for the purpose of balancing before the operations. finishing.
- This original arrangement of the balancing operation in the method of machining a crankshaft of the invention therefore has several advantages. On the one hand, it eliminates the operation of rebalancing by drilling the crankshafts at the end of their production chain by removing material and on the other hand, it ensures a dynamic measurement of the masses during an operation being particularly close to the operation of defining the starting points which ensures a O 01/09528 - 3 - PCT / FROO / 02141
- crankshaft machining chain is described below.
- Operation 1 realization of the starting points by geometric and or dynamic centering.
- Operation 2 realization of the ends of the crankshaft for turning and / or by leveling turning.
- Operation 3 Realization of the bearings by turning, leveling, turning-leveling and / or milling turning.
- Oil holes produced by drilling and / or drilling Oil holes produced by drilling and / or drilling.
- Operation 8 Roll burnishing.
- Operation 9 Finishing the bearings.
- Operation 10 Finishing of the crank pins.
- Operation 11 Finishing of the end fixings by drilling, tapping, milling bore.
- Operation 16 Phase called superfinishing.
- Operation 17
- the method of the invention is remarkable in that it consists in interposing between the operations of machining the ends, bearings and crank pins of the crankshaft and that of producing the oil holes in the crankshaft, a dynamic measurement of the masses of the machined crankshaft.
- the carrying out of a dynamic measurement at this stage of the crankshaft machining chain is particularly advantageous in that it is situated between the last consequent removal operation of material, that is to say the making of the oil holes and the penultimate operation, that is to say that of making the crank pins. Indeed, following the operation of producing the oil holes, there are the washing, heat treatment and burnishing operations, then those of finishing during which the removal of material is minimal or at least configurable.
- the machining process of the invention consists in carrying out the operation of removing material for balancing purposes during the operation of producing the oil holes on the crankshaft.
- the method of the invention obviate the drawbacks of the methods of the prior art but avoids the use of an additional machine tool for carrying out the rebalancing. Consequently, it is not a machine such as that provided for operation 15 which will be interposed between the dynamic mass measurement device and the production of the oil holes, but one and the same machine which will carry out the removal of material for making the oil holes and the weeding holes.
- the machining method of the invention is remarkable in that once the material removal operation for balancing purposes performed on the crankshaft, the latter is subjected to a dynamic mass measurement operation.
- the applicant provides for a dynamic measurement of the masses after removal of material for the purpose of machining and drilling of the oil holes. This phase makes it possible to check the quality of the balancing performed.
- the device making it possible to implement such a measurement can be used for the dynamic measurement of the masses both before the material removal operation and drilling of the oil holes, as after.
- the process of machining is of the type where the definition of the starting points is carried out by drilling the pre-machined ends of the crankshaft and that during said drilling the crankshaft is positioned on digital supports at its pre-machined surfaces
- the process of the invention is remarkable in that it consists in dynamically measuring the unbalance of the crankshaft after the operations of machining the bearings, crankpins and ends and in transmitting the measurements of this unbalance on the one hand to the device for removing material for balancing purposes in the event that the measured crankshaft can be balanced and on the other hand, to the crankshaft holding device when drilling the starting points in order to correct the location of the geometric center so that the unbalance of the following crankshafts at the end of machining can be balanced.
- the invention also relates to a device making it possible to implement the method of machining a crankshaft which is remarkable in that it consists on the one hand of a device for dynamic measurement of the unbalance of the crankshaft which has just been machined and on the other hand of a machine tool comprising the mobility necessary for carrying out drilling and drilling perpendicular or not to the axis of rotation of the crankshaft for balancing purposes.
- the machine tool constituting the device of the invention is of the type comprising a mobile flow on three axes and having a tool magazine.
- Such a machine tool will have the kinematic capacity to carry out drilling and drilling necessary for making oil holes and for scaling down using several tools.
- the flow of the machine tool is moved on its three axes by means of linear motors.
- Such a motorization will ensure the rapid realization of machining.
- the Applicant has also thought of using for this operation a process of the type known under the commercial name "digital ay" making it possible to inform the control part of the machine tool of the moment when the tool touches the workpiece making it possible to ensure very precisely a machining stroke.
- the device of the The invention advantageously comprises a transfer module ensuring the successive displacements of the crankshafts between the device for dynamic measurement of the unbalance of the crankshaft and said machine tool.
- This transfer module will therefore ensure the possible back and forth necessary for the proper balancing of the crankshaft before the operations following those of drilling the oil holes.
- the other advantage of this transfer module is that it does not wait for a possible measurement or verification of the balance of the crankshaft at the end of the chain in order to realize that the crankshaft has too much unbalance.
- this transfer module of the type ensuring that the workpiece is taken up in the measuring device and installed in the machining assembly of the machine tool and vice versa may have the function of producing the point connection between a crankshaft machining line and a machine tool of the type described above which can be integrated into another production line.
- Machining chains are particularly suitable when making small series of crankshafts. Also, not only, the method of machining the crankshaft and the device allowing it to be implemented have the advantage of using a single machine tool for carrying out from the removal of material for balancing purposes and for drilling oil holes but it also offers the possibility of operating a machine tool located outside the crankshaft machining chain or at least not exclusively dedicated to this machining chain.
- the dynamic mass measurement device can be used as a machining assembly adapted to the machine tool carrying out the removal of material for the purpose of balancing and for drilling oil holes.
