Definitions

  • This invention relates to improvements in copying lathes tor prod ucing turned articles that must be given a very exact circumference by using a copy or former in such a way that said circumference exactly corresponds to the copy or former used. for instance in turning of piston rings or the like. Hitherto in such turning a guide pin con nected with the cross slide of the saddle has usually been pressed positivetv against the tormer or copy fixed in achuck or tastened in a similar manner in such a way that the cross slide with the turning tool will be moved inwards or outwards during the rot-ation of the copy.
  • FIG. 1 is an end view of a machine constructed in accordance with the present invention.
  • Fig. 2 is vertical section through a lathe bed having the new apparatus mounted thereon in a form different from the one shown in Fig. I.
  • Fig. dis a similar section in two different planes to the right and left in the figure.
  • Fig. L t is a plan view of the lathe.
  • Figs. 5 and 6 are views in two different planes of a constructional detail.
  • patter giving the counter-tornier 7 its proper circumference dependent ol' the main-former in any other suitable way it may be placed in a. chuck or a driving plate of a lathe together with the main-former without changing its position in relation to the latter. and in such a way that its centre O (Fig. 3) coincides with the axis of the spindle of the lathe.
  • the cross slide 18 ot the lathe saddle 17 carries two arms 19 and 20 and on the ends of these arms rollers 21 and are provided one of which 21, is running along the circumference of the counter-former 7 and the other alone the circun'iterence of the main-former 1 in tlldlllCtl'lt'ttl opposition to the first mentioned roller when rotating the formers.
  • the arms and it) are adjustable in the longitudinal direction of the cross slide 18 and may be fastened in such a way that each of the rollers 2i and 22 is held againstv its former, as shown on the drawing.
  • the cross slide lo During the rotation of the spindle of the lathe the cross slide lo thus will move to and fro because it is displaced in one direction by the inain-forn'ier and in the other direction by the counterfornier. During this movement the rollers 21 and 2:2 will always simultaneously rest against the edges of their formers without any play whatever as is the case when weights, springs or other devices necessary for the movements of the cross slide are used and only one former.
  • the arms 15) and it) may oi course be locked in right po sition by any suitable devices.
  • FIG. l to b Another form of the invention is shown in Figs. l to b. It is not necessary that the points of contact between the rollers 2i and 22 and the formers T and l are exactly opposite each other on a diameter through the centre of the spindle of the lathe, as shown in Fig. 3, as they also may be arranged in some other way forming a more suitable form of the invention for practical use.
  • rollers are carried by the upper ends of two double armed levers 25 inountetil in bearings 2 fastened to the fast head stock of the lathe.
  • the lower arms of the levers 25 are pivotally connected with each other by n'ieans of a rod 26.
  • the length of this rod 26 corresponds to the distance. between the fulcrums of the levers so that a parallelogram is formed whereby the stun of the distances between the centre of the spindle of the lathe and the axis of the roll ers 21 and 22 always is the same. It is ad vantageous to provide.
  • the rod 22 with a turn-buckle 2? for the purpose of adjusting the length of the rod.
  • the levers 25 are mounted in the bearings 23 by means of hollow journals 2S fastened on the lovers and in which horizontal shafts 20 are keyed
  • the other end of each shaft rests in bearings 30 (Figs. 5 and ti) on the saddle 17.
  • the shafts 29 vertical arms 32 provided with a longitudinal slot 31 are fastened in front of the bearings 30.
  • An adjustable carrier 33 is made to slide in said arms and to be fastened to the same.
  • the carrier 5 may be locked in its tiil'l'erent positions by means of a nut 3i and on the side most remote from the arm 52 provided with a pin 35 engaging in a guide-way so on the cross slide i8. 'lhus when the main-former l.
  • the guide-way 36 fastened on the cross slide 18 may be provided with a special adjusting device in order to eliminate eventual play between the guide and the pin 35. This may be done by means of a bolt passing through a flange ll on the giii lo and an eye 12 on the cross slide.
  • a copying lathe comprising a main former, a guiding member cooperating therewith a counterformer, a second gu1d ing member cooperating with the count*rion double arm levers pivotally mounted on the fast head stock of the lathe for supporting the guiding members, an adjustable member connecting said levers, and means fixed to the levers for transmitting movement to the cross slide of the lathe.
  • a copying lathe comprising a main former and a counter-former, double arm levers, an adjustable member connecting said levers a guiding member carried by each lever and cooperating with a coarseu lar former, said guiding members being u1ntormly movable, the sum of the distances between the axis of the lathe spindle and the axis of the guidii'ig members being always constant during the turning of the levers, a head stock for the lathe. a cross slide for the lathe.
  • double arm levers mounted on shafts jonrnalled in bearings on the fast head stock of the lathe for supporting the guiding members, arms carried by said shafts for transmitting movement to the cross slide of the lathe, carriers in guideways in said cross slide, and means for adjustably securing said aims to said carriers.
  • a copying lathe comprising a main former and a cou11ter-':t'or1ner, the latter be ing turned in relation to the former through an angle less than 180. and guiding members cooperating with the respective tormers at points which are not diametrically opposed, the cou11tertor1ner having a form in such relation to the form of the main former that the sum of the distances between the points of contacts of the guiding members and formers and the axis of rotation is always constant.
