Definitions

  • the present invention relates to a machine for degreasing, blowing, drying or deburring various mechanical parts comprising a tool release device and positioning this tool around the part to be treated.
  • the treatment boxes are fixed and monobloc. It is therefore necessary to allow effective treatment to move the part to be treated so as to properly position it in the treatment boxes.
  • the devices according to the prior art require the installation of a mechanical clamping and movement means of the part, a means which is generally bulky and difficult to introduce into the supply boxes, which reduces the effectiveness of the treatment. .
  • GB-A-455810 relates to a method and an apparatus for the internal coating of metal containers.
  • Metal boxes are fed on a conveyor and are brought under the nozzles of a projection device.
  • the projection device is fixed and not removable.
  • FR-A-2120775 describes and illustrates a cleaning device in which there are provided means for spraying cleaning liquid over a tank.
  • EP-A-0201746 describes a cleaning device in which a tool support allows tilting of a workpiece by a spray nozzle located below said support.
  • the present invention provides a machine for degreasing, drying or deburring various parts in which the tools with their supply boxes move to allow the treatment of the part by enclosing it in the boxes or to facilitate the disassembly of tools by clearing all the boxes from the treatment area.
  • the machine according to the present invention consists of several elements that can be modulated with respect to each other and more particularly of a tool release module, a tool translation module and a tool rotation module. .
  • Each module can be driven either manually or automatically by an electric, pneumatic or hydraulic drive system.
  • the machine according to the present invention provides very significant advantages. These advantages are indicated below:
  • the machine can be used as well in the case of spraying a liquid, washing-degreasing, blowing, high pressure deburring.
  • the machine avoids moving the part to ensure treatment.
  • the machine makes it possible to effectively treat all the faces of the parts thanks to the translation of the tools.
  • the machine makes it possible to precisely position the tools relative to the part to be treated.
  • the machine translates the part to be treated perpendicular to the axis of translation of the tools.
  • the machine allows the release of the tools outside the treatment area.
  • the machine seals the treatment area in the working position.
  • the machine ensures great accessibility to mechanical elements in the treatment area.
  • the machine also allows quick access to tools (injectors or nozzles).
  • the present invention therefore provides a machine for degreasing, drying, deburring various mechanical parts comprising a tunnel constituting a treatment zone traversed transversely by a mechanism for conveying the parts to be treated, said mechanism being capable of being moved at will according to all predetermined sequences for bringing the parts to be treated into a plurality of boxes internally provided with tools for the treatment of parts and mounted in series along the conveying mechanism which is characterized in that each box consists of two adaptable boxes arranged in look at each other on either side of the conveying mechanism, said boxes being subject to drive and guide means capable of subjecting them to a translational movement in a direction perpendicular to the routing of the parts in order to nest them around the part to be treated during the working stage and the retract at the desired time after the work step to allow their accessibility outside the treatment tunnel.
  • the present invention also relates to the characteristics below considered in isolation or in all their technically possible combinations: - At least one box of a box is further subject to means imparting a rotation capable of rotating it laterally in the retracted position; - the means of driving the boxes consist of at least one cylinder; - The drive means of the boxes are constituted by at least one gear motor; - The guide means are columns passing through ball bushings; - The guide means are constituted by a pinion-rack assembly; - The means imparting rotation to a box in the retracted position outside the treatment tunnel is an orientation ring mounted at the top of a box and cooperating with a rotation blocking cam; - the boxes have an identical shape to form a parallelepiped box; - a plate with seal is provided at the rear of the boxes for sealing the treatment area in the working position; - Each box internally contains a plurality of tools such as projection nozzles.
  • the machine for degreasing, drying and deburring various mechanical parts 1 comprises a tunnel 2 constituting a treatment area 3.
  • a routing mechanism 4 for the parts to be treated 1 moves transversely in the tunnel 2.
  • Each box 5 consists of two adaptable boxes 6, 7, 8, 9 arranged opposite each other on either side of the routing mechanism 4. These boxes 6, 7, 8, 9 are subject to drive and guide means capable of subjecting them to a translational movement in a direction perpendicular to the conveying mechanism 4 of the parts to be treated 1 in order to fit them around it during the work step and retract them, at the desired time, after the work step to allow their accessibility outside the treatment tunnel 2.
  • the boxes 6, 7, 8, 9 with their tools translate on columns 12 by means of ball bushings 13.
  • Each box 6, 7, 8, 9 is driven in translation either by a jack 10 pneumatic or hydraulic either by an electric motor.
  • This assembly translates on columns 12 by means of ball bushings 13 and is driven in translation by a geared motor 11 by means of a pinion mechanism 14 rack 15.
  • the boxes on each side of the conveying means 4 are provided with a plate with seal 18 ensuring the sealing of the treatment zone 3 in the working position.
  • the box 7 with its or fillings (nozzles or injectors 19) is installed under an orientation ring 16 so as to allow its rotation to facilitate access to the tools, the box 7 being locked in rotation by a cam 17.
  • the position of the assembly is controlled electrically by a management cabinet not shown.
  • This assembly translates on the columns 12 by means of ball bushings 13 and is driven in translation either by a pneumatic or hydraulic jack 10 or by an electric geared motor 11.
  • a chassis 20 ensures the establishment and maintenance of the various modules used in the present invention.
  • the machine according to the present invention operates in the following manner:
  • boxes 6 and 7, 8 and 9 etc ... are brought into position around the part 1 to carry out the treatment. After a certain processing time determined by the management cabinet, the boxes 6 and 7 translate to release the part 1 and allow its transfer. When a tool in any box 6, 7, 8, 9 etc ... is damaged, the operator can either in manual or automatic completely disengage said box 6, 7, 8, 9 etc ... from the area of treatment 3 by means of the geared motor 11, the sealing plate 18 is no longer applied against the treatment zone 3, which allows easy access to the internal mechanism. On another side, when any of the boxes 6, 7, 8, 9 etc ...
  • Each box can include, like the box 7, a means of pivoting on itself constituted by an orientation ring 16 to gain access to the tools and an operator can carry out such an operation manually.
  • two boxes arranged opposite one another like boxes 6 and 7 fit perfectly one inside the other and in a sealed manner around the part 1 to be treated when one wishes to perform an operation and that in this position it constitutes a box 5.
  • each box dissociates into a box and in each box it is possible to carry out outside the treatment zone the desired operation.
  • the number of boxes arranged in series can vary at will depending on the number of operations to be performed. Thanks to the possibility offered by the present invention to be able to individually move one of the boxes and no longer have a monobloc box as was the case in the past, a much higher yield is obtained than was previously possible because the machine can operate from uninterrupted way.
