Definitions
- the known machines do not give whole satisfaction with the machining of cast iron crankshaft seats, the application pads used on these machines not being able to clear the graphite nodules from the staves, taking into account their hardnesses and their circumferential angles of contact with the surfaces.
- the machine object of the invention for strip machining abrasive of cylindrical surfaces on parts, in particular of journals and / or crankpins on crankshafts includes for the machining of a support surface on which three clamping elements of abrasive belt are mounted in a triangle while being mobile according to directions which converge towards the axis of the surfaces to be machined.
- Each clamping element carries at least one application pad shaped as so as to apply the abrasive strip against the surface following a surface essentially limited to a generator parallel to the axis of the scope.
- Each abrasive belt clamp can advantageously wear two application pads spaced in the direction circumferential, preferably from a distance such that the latter corresponds substantially to the distance between the successive pads of two consecutive clamping elements, for the average of extreme diameters of the surfaces likely to be machined on a same machine.
- each sanding pad application pad comprises, along the axis of the seat to be machined, two end parts greater hardness located on either side of a part intermediate of lower hardness.
- the parties end may have a Shore hardness of the order of 95 and the intermediate part a Shore hardness of the order of 65.
- Each clamping element 1 carries, on its turned surface 6 towards the bearing surface 4.1 to be machined, two pads 7 parallel to the axis 3, each consisting of a cylindrical log with an axis parallel to axis 3 of the litter, having a diameter smaller than the diameter of the litter 4.1.
- the two pads 7 of each element 1 are spaced from each other in the circumferential direction of a distance (angular) e1 slightly greater than the distance (angular) f1 between the two pads consecutive of two successive elements 1 whose pads 7 apply the abrasive belt 5 against the surface 4.1.
- Each shoe 7 is advantageously constituted by a material with a Shore hardness of less than 100, for example a elastomer as marketed under the COURBHANE brand by the COURBIS SYNTHESE of F-26100 ROMANS SUR ISERE.
- each clamping element 1 Given the presence, on each clamping element 1, two pads 7 with application surface in reduced diameter cylinder in relation to the diameter of the surfaces to be machined, it is possible to machine with the same clamping elements 1 carrying the same pads 7 of the ranges 4 of different diameters, as it appears in the comparison of Figure 1 with Figure 2 on which we recognize that the diameter of the bearing surface 4.2 to be machined is significantly smaller than 1st diameter of the bearing 4.1 of Figure 1.
- the (angular) distance e2 separating two pads 7 consecutive of two successive elements 1 is less than the distance (angular) f2 separating the two pads 7 from the same element 1, in contact with the scope 4.2.
- the distance f on each element 1 can be chosen so that it corresponds substantially to the distance e for the average of the extreme diameters of the spans 4 likely to be machined on the same machine with the same elements of tightening 1 equipped with the same pads 7.
- a surface 4 is machined using a strip abrasive 4 and clamping elements 1 with pads 7 (only one of which is shown) having a width less than the width of the litter 4.
- the printing elements are printed tightening 1, at their support, not shown, along axis 3 of the scope 4, a low speed oscillation movement so that the strip 5 performs, relative to the bearing 4 driven in rotation around its axis 3, a movement of sway symbolized by a dashed line in Figure 4, with a range of amplitude such that the seat is machined over its entire width.
