Definitions

  • the object of the present invention is an improvement in plane lapping machines with a double plateau.
  • the workpieces are stowed in housings which are provided in edge-toothed discs or satellites which are arranged in angularly symmetrical positions over the lower plane or plateau of the lapping machine.
  • the purpose of the invention is to provide a device which effects in a totally automatic way, at the end of each operating cycle, the removal operation of the satellites full of treated workpieces, the discharge of the latter on a conveying belt, the filling of satellites with pieces to be treated and the further arrangement of the satellites in the lapping machine.
  • a device which comprises a circular satellite-carrying plane near the side of the lapping machine, a passage plate or table located between the lower plane of the lapping machine and said circular charging plane, means for rotating step by step said two circular planes (that is the charging plane and the lower lapping plane) in synchronism with one another, a discharge station provided on said charging plane and communicating with a conveying belt, a feeding chute assembly intended for filling said empty satellites and a manipulating assembly of which the task is for removing in succession the satellites of which the workpieces have been treated and disposing them on said circular charging plane upstream of the discharge station, by passing them on the intermediate plate and for removing the full satellites and dispose them in the respective positions in the lapping machine.
  • Said manipulating assembly comprises a self­centering pliers provided with seizing means which is intended for engaging a center bore of the satellite and a pair of slide ways or guides which permit to said pliers to transfer each satellite from the operating machine to the charging plane and vice-versa by sliding over said intermediate connecting table or plate.
  • Said passage intermediate table or plate has an alternate horizontal movement with short stroke the purpose of which is for approaching it to the edge of the lower plane of the lapping machine upon the lowering of the driving crown of the satellites with the purpose of consenting to said pincers the transfer of the satellite on said intermediate table said intermediate plate being provided also with a vertical displacement which permits to the satellite and to the pincers a sufficient lowering down to the level of said circular charging plane.
  • the seizing pliers in addition to said transfer undergoes also a vertical displacement together with the intermediate passage table.
  • said manipulating assembly resumes its horizontal movement for transferring the satellite on said charging plane, in the station of arrival of the finished workpieces which comes before the next discharging station of the same workpieces on a conveying belt.
  • the feeding assembly of the workpieces to be lapped comprises a tank and a pair of channels or chutes which are arranged in correspondence with two series of housings for the workpieces which housings are provided in each satellite and are brought in correspondence to said chutes by a pinion which engages the toothed edge of the satellite.
  • number 1 indicates the whole of a lapping machine which is provided with a lower plane 2 and an upper plane 3 which, when pressed one against the other, actuate the lapping operation.
  • Such machine is not described in detail because it is well known and covered with other patents by same applicant and is illustrated in Fig. 1 where the two planes - which are also called plateau - 2 and 3 are spaced at the end of the working cycle.
  • satellites 4 On lower plane 2 are arranged, in angularly symmetrical positions, satellites 4 which are provided with a toothed edge and receive their rotation from a crown 5 which is partially shown in Fig. 2.
  • the assembly is provided for charging, discharging and transferring the satellites, in which assembly a mount 8 is included on which a circular charging plane 9 is mounted which is provided with radial stiffening ribs 10.
  • Charging plane 9 can support a number of satellites 12 and can rotate at intermittent speed about a central vertical axle 11 (Fig.1) of which it is provided. Satellites 12 are arranged on plane 9 at constant angular distances from one anothers. The turning speed of plane 9 depends on the number of satellites 12 which are located on plane 9 (which satellites are shown in a number of seven in Fig.2).
  • satellites 4 on the lapping machine (of which a number of five is shown in Fig.2) and the satellites 12 on the charging plane 9 are identical and then interchangeable but for better clarity they have different reference numbers.
  • a passage table 13 is provided of which the front edge 14 and the rear edge 15 are respectively shaped according to a circle arc concentrical with plane 2 of the lapping machine and with the charging plane 9.
  • a first plate or table 13 is connected with a second underlying plate 16 (Fig. 3) which at its turn can vertically slide along rods 17, due to cylinder 18, with respect to the frame which is formed by fixed side plates 19 which are anchored to the mount 8 and by the upper cross member 20.
  • the passage horizontal plate 13 can also effect a short horizontal travel being actuated by cylinder 21 of Fig. 3.
  • the latter actuates horizontally sliding rod 24 which is fastened to fork 25 having two sliding sleeves 26 which slide on horizontal slideways or guides parallel to cylinder 23.
  • Fork 25 in its front part carries head 28 which is provided with self-centering pliers 29 which can be moved vertically due to cylinder 30 and engage the center bore of each satellite.
  • a reservoir 31 is located which contains the workpieces to be lapped which reservoir has two feeding channels 32 and 33 the outlet ends of which lie in the vertical of the housings 7, 7′ of the workpieces.
  • a pinion 34 engages the teeth of satellites 12 so that the latter are rotated and said housings are filled with workpieces 7.
  • the operation is as follows: at the end of each operating cycle, the upper plate 3 is raised as shown in Fig. 1 and one of the satellites 4 with the finished workpieces is disposed in alignement with the passage plate or table 13.
  • the driving ring gear 5 is lowered and the passage table 13 advances so as to approach with its front curved edge 14 plate 2 of the lapping machine and head 28 of manipulating assembly advances until it moves pliers 29 to engage the center bore of satellite 4.
  • head 28 recedes and tranfers the satellite on charging plane 9 and disengages itself therefrom.
  • the charging plane 9 After setting the satellite in position A of Fig. 2, the charging plane 9 effects the rotation of a step in counter-clockwise direction as indicated by arrow F and the satellite reaches position B where at the finished workpieces are discharged on a conveying belt 35 which conveys them on a collection point.
  • the charging plane 9 rotates step by step and the various empty satellites which arrive from the discharge station B, - being rotated by pinion 34 - pass under the channels 32 and 33 and are gradually filled with workpieces to be lapped.
