Definitions

  • the present invention relates to a tool for grooming of cylindrical surfaces on parts, in particular pins and crank pins on crankshafts, with diameter control litters.
  • Grooming machines known by the patent application EP-A-0 366 506 by the applicant include, for each litter to be machined on a workpiece, a pivoting arm movable vertically, and three mounted sanding pad pads, a first one upper middle position on the arm and the other two in position low lateral on two jaws articulated on the arm and coupled so that they can be pressed together, in such a way that when tightening against the working surface, the three pads are arranged substantially at the three angles of an equilateral triangle.
  • the tape application pads abrasive have a circular arc application surface spanning a relatively small angle, usually less than 30 °. These tools work well for the condition of staff surfaces.
  • the honing and grooming machines using stones or pads extending over angles of more than 30 ° allow, by their enveloping form to better compensate for defects in shape (ovalization, runout, etc.) and defects in rectitude of the parts.
  • control gauge mounted on one of the jaws and comprising two opposite sensors, aligned, to measure the diameter of the span, during the machining of the latter, and possibly order machining stops when this diameter reaches a value predetermined.
  • the Applicant is not aware of the use of a diameter control device on a grooming tool comprising three enveloping pads arranged in a triangle, the first on one arm and the other two on two jaws articulated on said arms.
  • the present invention relates to a tool for the application of abrasive belt against cylindrical surfaces to be machined on parts, including crankshaft journals and crank pins, with checking the diameter of the spans, this tool comprising pads enveloping to meet stringent requirements regarding the absence of defects in form, the straightness and the precision of the spans.
  • the tool object of the invention is intended for the application of abrasive belt on a machine for grooming spans cylindrical on parts, in particular trunnions and crank pins on crankshafts, comprising for each bearing to machine an arm swivel and movable vertically, and three tape application pads abrasive mounted first in the middle position on the arm and both others in low lateral position on two jaws articulated on the arms and coupled so that they can be tightened against each other, in such a way that when tightening against the work surface, the three pads are arranged substantially at the angles of a triangle equilateral.
  • the arm carries a first pad having a surface abrasive band application concave extending over an angle greater than 90 ° and less than 180 °.
  • the arm also carries a caliber control with two opposite sensors aligned horizontally, located below the two angular ends of the first shoe, to measure the diameter of the seat to be machined.
  • Each of the two jaws wears a second pad having a concave application surface an abrasive strip extending over an angle slightly less than 90 °, in such a way that when clamped around the work surface, the three pads cover the surface to be machined at least 270 °, the first above and the two seconds below the two caliber sensors located on the same diameter of the span.
  • the first shoe and the caliber are fixed to a support mounted on the arm with limited mobility in translation horizontal perpendicular to the axis of the seat to be machined.
  • Both second pads can be mounted on their jaws with a limited mobility in oscillation around axes parallel to the axis of the scope.
  • the support of the first skate and the caliber is advantageously mounted on the arm also with mobility limited in oscillation around an axis perpendicular to the axis of the worn to machine.
  • Said axis of articulation of the support preferably passes to short distance above the axis of the seat to be machined.
  • the grooming and control according to the invention is used on a machine according to the Patent application EP-A-O 366 506 for the abrasive machining of cylindrical bearings on parts, especially for machining by grooming of crankshaft journals and crankpins.
  • an arm 1 mounted freely pivoting around a horizontal axis on a non-sliding shown moving vertically.
  • the arm 1 carries two jaws 2a, 2b articulated by horizontal axes 3a and 3b on the arm 1 and coupled by toothed segments 4a, 4b so that they can be pressed against each other by synchronous pivoting in opposition by relative to the arm 1, under the action of a common actuating cylinder 5.
  • a first pad 7 is mounted in the upper middle position on arm 1 and two second pads 8a and 8b are mounted in the low lateral position on the two jaws 2a and 2b in such a way that when, after lowering of the arm 1 to bring the first skate 7 on the scope to be machined, the three pads 7, 8a and 8b are tightened, under the action of the jack 5, against the scope 6, for the application against this scope 6 an abrasive strip 9, the three pads 7, 8a and 8b are arranged substantially at the three angles of an equilateral triangle. Because of balancing the mass of arm 1 by a non-balancing means shown, for example a jack with controlled supply pressure, the three pads are thus applied with substantially pressure uniform against the bearing surface 6 to be machined.
  • the first pad 7 presents, for the application of the strip abrasive 9 against the surface 6 to be machined, a concave surface of application extending over an angle slightly less than 180 °, in the occurrence on an angle of about 160 °.
  • the two second pads 8a and 8b have, for the application of the same abrasive strip 9 against the scope 6, each a concave application surface extending over an angle slightly less than 90 °, in this case on an angle about 70 °.
  • each second skate 8a, 8b covers approximately a lower quarter of the scope 6, two diametrically opposite free spaces remaining between each of the two angular ends of the upper shoe 7 and the corresponding upper angular end of each shoe lower 8a, 8b.
  • the two lower pads 8a, 8b are mounted on the jaw 2a, 2b respectively by pivot axes 12a, 12b parallel to the axis of the scope 6, so as to present, as indicated by arrows 11a and 11b, limited mobility in oscillation around the axes 12a, 12b.
  • the upper shoe 7 is mounted on a U-shaped support 13 overturned whose two arms 14a, 14b carry, at their end lower, each a pin 15a, 15b, the two pins 15a, 15b being aligned horizontally on an axis perpendicular to the axis of the scope 6 and being pivotally mounted and movable in translation according to their axis on the lower ends of a yoke 17 fixed to the arm 1.
  • An inverted U-shaped control gauge 16 comprising two opposite aligned sensors, is also fixed to the support 13 carrying the upper shoe 7, so that its two sensors, when the three jaws 7, 8a and 8b are clamped against the bearing surface 6 to be machined, are located on a horizontal line corresponding to the diameter of the scope 6 and thus measure the diameter of the latter.
  • the abrasive strip 9 arrives between the two lower pads 8a, 8b, for example passes between the pad 8b and the bearing surface 6, then departs of range 6 to bypass one of the 16 gauge sensors, pass on a return roller, returns to the bearing 6 to pass between the upper shoe 7 and the bearing 6, then deviates again from the reach 6 and passes over a deflection roller, to bypass the other 16 gauge sensor, then returns to range 6 to switch between pad 8a and the bearing surface 6, and finally comes out between the two pads 8a and 8b.
  • the upper shoe 7 could extend over an angle lower, but greater than 90 ° and preferably greater than 120 °
  • the lower pads 8a, 8b could each extend over an angle lower or more important, but preferably between about 60 ° and 80 °, so that the three pads 7, 8a and 8b wrap staff 6 together as completely as possible, preferably on an angle equal to or greater than 270 °.
  • the sensors of the measurement gauge 16 can, within the framework of the invention, be constituted by sensors of known type, by example of electronic or pneumatic sensors.
