Definitions

  • the present invention relates to the technical field concerning processing of mechanical parts.
  • the present invention relates to a device for supporting mechanical parts while being processed, particularly indicated for parts made of aluminum and aluminum alloys.
  • the mechanical parts are pump bodies, usually made of aluminum, the processing requires high precision and the dimensional tolerances are extremely reduced.
  • pairs of opposite surfaces respectively flat longitudinal, flat transversal and curved lateral surfaces, are defined.
  • the processing of the surfaces of the pump bodies with the use of known rotating turrets comprises two distinct steps, defined substantially by processing of the flat longitudinal surfaces and flat transversal ones.
  • the operator places preliminarily each pump body on the rotating turret in a first processing station between a first pair of pads, one motionless and another moving.
  • the first pads allow to fasten the part on the curved surfaces, so that the two flat longitudinal surfaces are accessible to be processed.
  • the operator Upon completion of the processing of the longitudinal surfaces, e.g. for making one or more through seats of prefixed dimensions, the operator disengages the semi-finished product from the first pads.
  • the operator places each semi-finished product on the same rotating turret in a second processing station, between a second pair of pads, one motionless and the other moving.
  • the operator After processing the transversal surfaces, e.g. for making one or more through seats of prefixed dimensions, the operator disengages the processed part from the second pads.
  • the object of the present invention is to avoid the above mentioned disadvantages by proposing a supporting device for mechanical parts, particularly indicated for parts in aluminum or aluminum alloy, which ensures an extremely precise and rapid processing cycle, characterized by high production rate.
  • a further object of the present invention is to propose a supporting device, which can facilitate positioning of the mechanical parts, simplifying the automation of the work steps, ensuring at the same time extremely reduced processing tolerances.
  • the general reference number 1 indicates the proposed supporting device for mechanical parts 3, made of e.g. aluminum or aluminum alloy, defining a pair of opposite heads 3a, 3b and a plurality of lateral surfaces 40, 41, 42, 43.
  • the Figures show mechanical parts 3 comprising a pair of opposite curved heads 3a, 3b, a first pair of opposite lateral surfaces 40, 41 and a second pair of opposite lateral surfaces 42, 43.
  • the proposed supporting device 1 includes a frame 5, having a first platform 50, to which at least one connecting element 51, e.g. an upright, is associated to support a second platform 52; first abutment means 6, associated to the first platform 50 and aimed at supporting a first head 3a of a mechanical part 3; second abutment means 8, associated to the second platform 52 and aimed at locking a second head 3b of the mechanical part 3; actuating means 7, associated to at least one platform 50, 52, aimed at operating the first abutment means 6 and the second abutment means 8 to move relatively close/away, respectively for locking/unlocking the part 3 within the frame 5, so as to make the lateral surfaces 40, 41, 42, 43 of the mechanical part 3 accessible to the mechanical processing along at least two main processing axes X, Y, substantially orthogonal to each other, after locking the mechanical part 3.
  • first abutment means 6 associated to the first platform 50 and aimed at supporting a first head 3a of a mechanical part 3
  • the first platform 50 is situated at a lower level with respect to the second platform 52, and the actuating means 7 are fastened to the upper platform 52 and operate the second abutment means 8 to move close/away with respect to the upper head 3b of the mechanical part 3, respectively to lock/unlock the part 3 within the frame 5, in cooperation with the first abutment means 6.
  • the proposed device 1 can include actuating means 7 fastened to the lower platform 50 and operating the first abutment means 6, or associated to both platforms 50, 52 to operate the respective abutment means 6, 8 to move close/away to each other.
  • the frame 5 rotates advantageously on a substantially vertical axis A, and for example, the lower platform 50 has four uprights 51 for supporting the upper platform 52.
  • the uprights 51 connecting the platforms 50, 52 are arranged at the vertices of the platforms 50, 52 and oriented according to corresponding vertical axes B, positioned in such a way, as not to obstacle the mechanical processing performed along the main processing axes X, Y.
  • the first abutment means 6 include at least one lower jaw 60, fastened to the lower platform 50, to which a plurality of first supporting elements 61 are associated to support the lower head 3a of the mechanical part.
  • a pair of first supporting elements 61 both stationary with respect to the lower jaw 60, are aimed at supporting bilaterally the lower head 3a of the mechanical part 3.
  • the first supporting elements 61 can be both tilting with respect to the lower jaw 60, on an axis parallel to a first main processing axis X, or one of them can be tilting and the other stationary.
  • the second abutment means 8 include at least one upper jaw 80, which are operated by the actuating means 7 and to which a plurality of second supporting elements 81 are associated to hold the upper head 3b of the mechanical part 3.
  • the actuating means 7 include a jack, operated pneumatically or hydraulically (preferably the latter), acting on at least one pressure level for each mechanical processing.
  • the second jaw 80 is advantageously tilting with respect to a pushing plate 90, operated by the stem of the hydraulic jack 7 along an axis parallel to a second processing axis Y.
  • a pair of second supporting elements 81 both tilting with respect to the upper jaw 80 on an axis parallel to the first main processing axis X, hold bilaterally the upper head 3b of the mechanical part 3.
  • the second supporting elements 81 can be both stationary with respect to the upper jaw 80, or otherwise, one of them can be stationary and the other tilting.
  • FIG. 5 there can be a plurality of lower jaws 60, having a number of first supporting elements 61, cooperating with corresponding upper jaws 80, which have a related plurality of first supporting elements 61.
  • the lower jaw 60 - upper jaw 80 including groups are advantageously aligned along an axis Z, so as not to obstacle the mechanical processing performed along the main processing axes X, Y.
  • the positioning of the mechanical part 3 interposed between the abutment means 6, 8 is preferably performed by robot-operated manipulating means, which ensure extreme precision and rapidity, automating the relative loading and unloading procedures.
  • the mechanical part 3 can be positioned manually by an operator, with the advantageous help of third abutment means (operated manually or automatically), which define an abutment for the mechanical part 3 being positioned, and which are later operated to retract during the mechanical processing steps.
  • third abutment means operated manually or automatically
  • the mechanical processing of the parts 3 occurs in one global step, since subsequent operations are allowed on two distinct main processing, orthogonal axes X, Y, without disengaging the parts 3 from the abutment means 6, 8.
  • Mechanical processing operations can be performed also on secondary axes, inclined with respect to the main processing axes X,Y, depending on the accessibility of the lateral surfaces 40, 41, 42, 43.
  • the maximum accessibility of the lateral surfaces 40, 41, 42, 43 is allowed by the presence of a single upright 51, connecting the platforms 50, 52, although it is extremely great also in case of four uprights 51, situated at the vertices of the platforms 50, 52.
  • the proposed supporting device 1 allows to choose the chronological succession, with which the mechanical processing operations are to be performed, achieving at the same time optimal final precision.
  • the production rate of the whole processing cycle, along both main processing axes X, Y is extremely high, since it is possible to act on the mechanical parts 3 with optimum cutting speed and thus higher with respect to the prior art, without moving the parts 3 between two different work stations, as it occurs in the prior art.
  • the proposed supporting device allows to reduce remarkably the final deformations caused by structural tensions, which involve the parts 3, made in particular of aluminum or aluminum alloys, during the processing steps, along the two main axes X, Y, as well as during the steps following the disengaging the part from the abutment means 6, 8.
