Definitions

  • the present invention has for its object a process for controlling the displacements of a mechanical member adapted to be moved by translation such as, more particularly, a tool holder, which process permits of transmitting to said member displacements of a variable amplitude with equally variable feed motion rates, without interposition of any step-up or step-down gear elements.
  • the invention has also for its object an improved cam device embodying the principles of said process.
  • a cam device rotatable by a cam shaft through an angle not exceeding 90 for imparting to the displaceable element a unidirectional feed motion of the character described comprises a pair of eccentrics of equal eccentricity of which the first, or inner eccentric is mounted on the cam shaft and second, or outer eccentric, on the inner eccentric, together with a feed imparting cam follower displaceable by the outer eccentric along a straight line passing through the cam shaft axis, the outer eccentric being angularly adjustable with respect to the inner for selectably varying the feed stroke by selectably varying the sinusoidal law according to which the feed proceeds.
  • the process according to the invention finds a particularly interesting application in the control of the transversal feeding movements of the tool in horizontal tool lathes and especially in screw-cutting machines working with a tool.
  • the sinusoidal law according to which the rotation of the cam device is transmitted to the feed motion of the tool makes it possible, through a connection, which can easily be performed mechanically, of said rotation with the longitudinal movementof the tool,
  • adjusting means adapted to settle independently the angular position of the outer eccentric with respect to the inner eccentric, and of the inner eccentric with respect to the driving shaft, both adjustments permitting of varying, on the one hand, the amplitude of displacement of the controlled member, and, on the other hand, the feed motion rate of said displacement.
  • Means are provided to indicate the relative angular positions of the eccentrics and the driving shaft.
  • the inner eccentric is clamped onto the driving shaft by means of a conical helving and comprises a radial slot which allows said inner eccentric expanding in the bore of the outer eccentric, the whole being clamped onto the driving shaft by means of a nut or like organ.
  • a conical helving for adjusting the relative angular positions of the outer eccentric with respect to the inner eccentric and of the latter with respect to the driving shaft, it is only necessary to unscrew the nut and to rotate each eccentric of the desired angle, and then to screw said nut.
  • Controlling fingers or rods may advantageously be connected with each eccentric to allow said double adjustment being more easily effected.
  • Figure 2 is a similar view of the outer eccentric of said cam device
  • FIGS. 3 to 8 are explanatory views and diagrams showing the use of such a cam device
  • Figure 9 is an elevational view of one embodiment of the cam device in the original position corresponding to Figure 1, the nut and the checks of the outer eccentric being removed;
  • Figure 10 is a view similar to Figure 9 of the cam device entirely built up;
  • Figure 11 is a cross sectional view, through line XI-Xl of Figure 10.
  • variable cam device embodying the principle of this invention consists of a circular central body a with a radius R and center 0, clamped onto a shaft b, the axis of which goes through 0.
  • a first eccentric ring 0 the outer outline of which is a circumference with a radius R1 and center 01 and which comprises a bore with a radius R and center 0 allowing it turning about the body a.
  • a second eccentric d the outer outline of which is a circumference with a radius R2 and center 02 ( Figure 2) and which comprises a bore with a radius R1 and center 9.
  • Eccentric d can rotate about eccentric c, the center 9 of its bore permanently coinciding with center 01 of the outer outline of eccentric c.
  • the eccentric ratio 029 of eccentric d is equal to eccentric ratio 010 of eccentric c so that there is one and only one position for which 02 coincides with O, the outer outline of eccentric d then being centered on shaft b and the cam device being a circle of a radius R2 concentric to said shaft. This position is shown in Figure 1.
  • eccentric d On eccentric d are marked graduations A, B, C spaced, for instance, at angular intervals of 5, and on eccentric c is provided a reading index T which, in the above defined neutral position in which the outline of ring d is concentric with the rotation axis of shaft 1), registers with graduation A.
  • a setting angle 1.7 is given to eccentric d with respect to eccentric c ( Figure 3)
  • the length 002:6 which defines themaximum amplitude of such displacements depends on the number of divisions A, B, C brought above the mark T, i. e. on the angle of Figure 3.
  • the value of 6 with respect to radius r of eccentricity is given by the relation:
  • the cam device comprises a central body a which is constituted by aconical-sleeve in three parts andlis clamped on the end of a shaft 1) fitted with a shoulder b1. Said conical part could be formed on the shaft b itself,
  • the inner eccentric c is hollowed with a conical bore which allows for.
  • the eccentric being clamped on sleeve a, and is slotted at 01 in its widestpart so that it possessesthe greatest possible elasticity.
  • the inner eccentric c is hollowed with a couical bore which .allowsfor said eccentric being clamped on sleeve (1, and is slotted at m in its widest part so. that it possesses-the greatest possible elasticity.
  • Theinner eccentric'c is itself surrounded by an outer eccentric d of identical eccentric ratioand which is maintained in position by means of two, cheeks e fastened on eccentric c,-by means of screws 11. The whole is clamped onto the shaft b by means of a washer and a locking nut j, advantageously of long thread, screwed on the end of said shaft.
  • the reproducing organ adapted to transmit the cam action, for instance, to the tool holder of a screw cutting 4 machine, is constituted here by a sector It fitting the outline line of outer eccentric d and which is pivotally mounted onto a shaft I supported by an organ (not shown) in relation with the tool holder.
  • the working line of the piece k is formed by the alignment of the centers of the pivot landlshaftibn r in order to adjust the angular position of the outer eccentric d. with respect/to the inner eccentric c, which position determines the choice of the sinusoidal law according to which the displacement of the reproducing organ will be controlled, a controlling rod-m is fastened laterallyon said eccentric. d.
  • the relative angular positions of a a11d;,c are marked, for instance, by means of a graduation formed of letters carried by the eccentric d opposite an index T carried by the outer cheek :2.
  • Another controlling rod 11, formed, by way of example, by av lengthening of one of the screws h, allows controlling the angular. position of inner eccentric c with respect'to the shaft b, which position determines the part of the sinusoid which is-actually eifective for controlling the displacement of the reproducing organ.
  • a graduation with figures carried by eccentric d in front of an index T carried by the piece k allows determining the position thus imparted to eccentric c.
  • An apparatus for pred'et'ermining the feeding movementsjof the working instrument of a machine tool throughoutits working cycle comprising a rotatable shaft operatively drivenby the machine, a control cam rotatable with said shaft and adapted to impart feeding movements to said working instrument, said control can] including a pair of.
  • eccentrics one mounted within the other and the inner eccentric being mounted on the rotatable shaft, the outer eccentric being angularly adjustable relativeto the inner eccentric for determining the sinusoidal law' of tool feeding movements and the inner eccentric being angularly adjustable with respect to the shaft for determining the point on the sinusoid at which feeding movements commence, and means for clamping said eccentrics on the shaft in theiradjusted position, said clamping meanscomprising a conical sleeve adapted to be secured between the shaftian'd the inner eccentric, plates fixed to opposite sides of the inner eccentric and engaging the sides ofthe. outer eccentric for niilitating against relative..axial movernents of said eccentrics, and screw means o n the shaft to impart axial movement to said sleeve relativetothc inner eccentric.
