Definitions

  • the present invention relates to improvements in machines for washing machined parts.
  • the invention relates to improvements in machines of the type of those which on a common bench include bars for transferring the parts to be washed, at least one washing station where the part is completely or partially immersed in a tank which contains a washing liquid which is preferably subjected to riddling, this washing liquid having its origin from the pressure organs which take it in turn from a filtering system, washing liquid which is collected beforehand, dirty, below the station washing and then leads to the mentioned filtering system; at least one compressed air blowing station; at least one drying station; stations at the end for loading the parts to be washed and for discharging the washed parts, respectively; finally intermediate waiting stations, so that the parts intended for washing are supplied by the transfer bars, equipped with a movement of "no pilgrim", on the relevant elements of transverse transport comprising support frames held by a vertical retaining wall, by successively introducing them into the tanks or envelopes of the side washing, blowing and / or drying stations, then removing them from the stations mentioned.
  • washing machine operations are well known in which the washing of the machined parts is done by immersion inside a bath of bathing liquid.
  • all of this type of machine has the serious disadvantage of swallowing up a considerable amount of washing liquid, which is wasted during the introduction or removal of the part from the washing tub.
  • the dimensions of the washing tanks mean that the emptying and filling, necessary for each washing operation, turns out to be operations whose completion time is relatively long, which turns to the disadvantage of the performance of the machine.
  • each tank is provided a side opening adapted to allow the entry and exit of the relevant support frame carrying a part, being arranged inside the tank, in the washing liquid, a hollow shell intended to wrap, without a excessive play, the part-support assembly, this hollow shell comprising a single lateral opening, the mouth of which has a contour slightly greater than that of the lateral opening of the tank, the hollow shell mentioned being provided with a reciprocating movement -and comes in horizontal alignment with the movement of movement of the corresponding support frame in the transverse direction relative to that of the advance of the parts, so that during the transverse movement of discharge / load of a part the hollow shell is moved towards the lateral opening of the tank and the edge of the mouth tightens firmly against the inside rim of the mentioned opening of the tank, by closing it tightly and preventing it from leaving the outside washing liquid between the outer surface of the shell and the inner surface of the tank, while during the washing operation the shell remains recessed towards the inside of the tank, ensuring that the part has
  • the aforementioned hollow shell is provided with a drive mechanism, external to the tank, which preferably acts on an arm which is integrally attached to it and which emerges from the tank through an opening from which it is provided on its upper part.
  • the mouth of the lateral opening of the hollow shell is provided with a seal.
  • the external mouth of the lateral opening of the tank is provided with a seal.
  • lateral deflector screens are fixed, integral with the vertical retaining wall mentioned and / or the tank, adapted to avoid side splashes when draining the washing water contained in the hollow shell.
  • the vertical retaining wall is preferably constituted by two independent half-walls, each of which is associated with a respective support frame and is facing a corresponding washing station.
  • the arrangement of the support frames (1,2) is integral with a vertical retaining wall (3) connected to a carriage (4) driven by a hydraulic cylinder (5) or by any other mechanism capable of imparting a movement of va- back and forth.
  • the transfer bars (6) convey the parts (22) to be washed to the relevant support frames (1,2) which take them at the appropriate time by unloading them after washing on the transfer bars themselves (6) .
  • the invention provides the arrangement inside the tank (8), in the washing liquid, of a hollow shell (10) intended to wrap without excessive play the assembly formed by the part (22) and the support frame (2), this hollow shell (10) comprising a single lateral opening (16) whose contour of the mouth is slightly greater than that of the lateral opening (15) of the tank ( 8].
  • This hollow shell (10) mentioned has a back and forth movement in horizontal alignment with the movement of movement of the relevant support frame (2) in the transverse direction relative to that of the advance of the parts ( 22).
  • the hollow shell (10) is moved towards the lateral opening (15) of the tank (8) and the edge of the mouth ( 17) does it apply firmly against the internal rim of the side opening (15) mentioned of the tank, achieving a hermetic closure of the latter and preventing the exit outside of the washing liquid between the surface external of the hollow shell (10) and the internal surface of the tank (8) (fig. 3 and 4).
  • the hollow shell (10) remains recessed towards the inside of the tank (8) (fig. 2), ensuring that the part (22) is accessible to all of the washing liquid contained in the tank (8), this lateral opening (15) mentioned of the tank being provided with a mouth (18) oriented towards the outside and the purpose of which is its application against the vertical retaining wall (3) during the washing operation, achieving a hermetic closure of the lateral opening (15) of the tank during this washing operation.
  • a part (22) is introduced into the tank (8) through the lateral opening (15) of the latter by means of the transverse displacement of the relevant support frame (2), achieving the hermetic closure outside the lateral opening (15) of the tank by means of the support of the vertical retaining wall (3) on the external mouth (18) of this lateral opening (15), the hollow shell (10) then taking a withdrawal position towards the inside of the tank (8), the washing operation being carried out and once this has been completed, the hollow shell (10) is again applied against the lateral opening (15) of the tank, closing it hermetically inside, the vertical retaining wall (3) of the external mouth (18) of the opening side wall (15) moves away, which causes the interior of the hollow shell (10) to drain, also moves the support frame (2) to the transfer bars, the washing station then being ready to receive a new part (22) and start a new washing cycle.
  • the hollow shell (10) is constructed in such a way that it conforms most closely to the configuration of the support frame (1,2), in order to minimize the volume and to minimize the emptying and filling with washing liquid. This means that this hollow shell (10) can take irregular shapes to achieve the stated purpose.
  • the hollow shell (3) is provided with a drive mechanism, external to the tank (8), which preferably acts on an arm (19) being integrally connected to it and which emerges from the tank (8) through an opening ( 20) which it has on its upper part.
  • the arm (19) is integral with a carriage (11) which slides on the rollers (12), driven by the hydraulic or pneumatic cylinder (13).
  • This drive mechanism is that which provides the mentioned back-and-forth movement with which the hollow shell (10) is provided.
  • the mouth (17) of the lateral opening (16) of the hollow shell (10) is provided with a seal (14).
  • the external mouth (18) of the lateral opening (15) of the tank (8) is provided with a seal (21).
  • the washing liquid contained in the hollow shell (10) falls vertically through the hollow defined by the wall of the tank (8), the wall (3) and the screens (23,24).
  • the screen (24) is internal and integral with the tank (8), the lateral deflector screens (23,24) mentioned remaining on the 2 sides of the wall (3). On the upper part there is no need to fix a screen, by the lower part the washing water falling to a collector of dirty water.
  • the vertical retaining wall (3) mentioned is preferably constituted by two independent half-walls (3a, 3b), each of them being associated with a respective support frame (1,2 ) and being next to a corresponding washing station (fig. 2).
