Definitions

  • the invention relates to a support device for motor assembly, for supporting complex and heavy elements, such as motors.
  • Examples of such devices include assembly pallets for supporting and transporting, on an assembly line, motor vehicle engines.
  • assembly pallet comprises a plate, to which are fixed candles, the candles forming vertical supports, having upper bearing surfaces of shape adapted to come there to pose additional bearing areas of a housing of engine. The engine is thus maintained in a fixed position relative to the plate under the effect of its weight.
  • the upper support ends of the candles may typically have flat surfaces, intended to abut against opposing plane surfaces machined locally on the motor housing. Some candles may also include bearing pins, intended to be inserted into the corresponding centering holes of the motor housing.
  • the same pallet can therefore include a first group of candles, intended to support a first model of engine, and a second group of candles to support another model of engine.
  • candles of the second group which do not form also support for the first engine model, do not interfere with the engine. So we sometimes use trays with removable candles, or with candles mounted on a rotating base, so as to be able to position certain candles in a first position when they have to support the engine model to which they are dedicated, and so as to be able to position the candle in minus a second position, allowing the candle to support another engine model.
  • the support device may further comprise a rotary base, rotatably mounted around the first candle, and carrying a height wedge secured to the rotary base so that the wedge comes, for a first angular position of the rotary base, to be superimposed over the support end of the second candle so as to enhance the support area provided by the second candle, and so that the hold can be released from the end of the second candle for a second position of the second candle rotary base.
  • the rotary base is configured to use a cylindrical outer surface of the first candle as a rotational bearing surface. This avoids having to set up an axis of rotation specifically dedicated to the mobility of the base.
  • the axis of the first candle is parallel to the axis of the second candle.
  • the axes of the first candle and the second candle may for example be perpendicular to the same reference plane of the base.
  • the height wedge secured to the rotary base is in a position spaced from both the first and the second candle, so as to leave free access to the ends of the two candles and the space between the two candles.
  • the rotary base may comprise an annular portion surrounding the first candle, of height substantially less than the height of the first candle and the height of the second candle, and may comprise a leg extending at least partly vertically from the base rotating, and supporting the wedge height relative to the annular portion of the rotary base.
  • candlelight is meant here a substantially vertical support element relative to a reference plane of the base, considered horizontal.
  • the height of the rotary base is less than or equal to one third of the height of the first candle, and is less than or equal to one third of the height of the second candle.
  • “height” is meant at a distance from the rotary base in the direction of support of the candles against the engine, bearing direction which generally corresponds to the vertical direction. In some particular cases, it may be possible to envisage using the device to exert a non-vertical holding pressure on well-chosen support zones of the engine, but it may, however, be necessary to block the motor between two supporting devices each in an opposite direction.
  • the axis of the lug carrying the shim may be parallel to the axis of the first candle, and be configured to rotate about the axis of the first candle.
  • the tab can form a sleeve surrounding the first candle, the sheath being configured to rotate about the axis of the first candle.
  • the shim can then be connected to an upper portion of the sheath, for example by a radial connection portion, or by a connecting portion in an arc, this arcuate portion leaving clear the space between the first and the second candle when the second candle is covered by the hold.
  • the wedge and the leg can be configured so that, during rotation of the base, the wedge comes to cover the second candle leaving the leg behind the second candle. Aft of the second candle is behind the candle in relation to the circular approach path of the hold towards the second candle. This leaves the gap between the first and second candles when the second candle is covered by the hold.
  • the rotating base can carry a third candle, which is thereby movable relative to the first and second fixed candles.
  • the wedge may optionally comprise two different heights, depending on the level of angular overlap of the second candle by the wedge.
  • the second candle can thus be raised by two different heights according to the angular position of the base to which the wedge is connected.
  • the hold covers the second candle if it is placed so as to raise a support zone of the second candle, even if the hold does not completely cover the upper part of the second candle.
  • the top of the second candle may include a central pin, and the wedge may be split to engage around the piece.
  • the first candle can be held on the base by a fixed base, the fixed base defining an upper face raised relative to the base.
  • the rotary base may advantageously comprise a lower face placed on the upper face of the fixed base. The rotation of the rotary base is thus facilitated.
  • the upper and lower faces may be planar, or may include indexing reliefs to facilitate the positioning and / or maintenance of the rotary base in predefined relative angular positions relative to the fixed base.
  • the support device may comprise an elastic device configured to press the rotary base against the fixed base.
  • the elastic device may for example develop a plating force between 1N and 10N, thus allowing the rotary base to be raised manually relative to the fixed base to place it in another angular position.
  • a transport device for a motor assembly line comprising a support device as described above, and comprising a transportable tray forming the base of the support device.
  • the transportable tray is for example able to be moved along a production line.
  • An engine assembly pallet may for example comprise a plate, comprising a plate mounted parallel to the plate to rotate relative to the plate, the plate forming the base of a support device as described above.
  • a motor assembly pallet referenced 20 comprises a transportable tray 13 on which is rotatably mounted a rotary plate 12, rotatable relative to the plate 13, so as to position the plate 12 at different angles with respect to a operator on one side of the pallet 20.
  • the rotary plate 12 forms a base for a group of candles 1, 2, 3, 4, 5, 6, mounted thereon so as to protrude perpendicularly to the plate 12.
  • the group of candles is erected vertically with respect to the upper face 10 of the plate 12.
  • Each candle has an upper end, respectively 21, 22, 23, 24, 25, 26, configured to abut a complementary bearing area of a motor housing adapted to be supported by the assembly pallet 20.
  • All candles are not configured to support the same motor.
  • Some of the support ends are flat, for example 21, 22, 23, 25, and others comprise a bearing pin, for example here the ends 24, 26 respectively comprise a bearing pin 34 and a pin of support 36.
  • some of the candles can see their radial size locally reduced by vertical flats, as is the case for example for the first candle 21 and the fifth candle 25.
  • the pallet 20 illustrated in figure 1 comprises five fixed candles, namely the candles 1, 2, 4, 5, 6.
  • the candles 1 and 2 are surrounded by the fixed base 11 raised with respect to the surface 10 of the plate 12.
  • the candle 3 is rotatably mounted around the candle 1, via a rotary base 9 carrying the candle 3, and a lower face 15 bears on an upper face 14 of the fixed base 11 surrounding the base of the first candle 1.
  • the candle 3 can be placed in a suitable first position to support the engine associated with it, or may be on the contrary excluded angularly from the first position to respect the size of another engine.
  • the group of candles 1, 2, 3 is part of a support device 30 with a variable configuration, making it possible in particular to modify the configuration in the space of the support ends available at the ends of the candles 1, 2, 3 to support the one or the other engine intended to be placed on the pallet 20.
  • the rotary base 9 supports, in addition to the candle 3, a height shim, reference 7, mounted on a substantially vertical carrying rod 8, so as to be able to superimpose the wedge 7 with the bearing zone 12 of the second candle, and to raise the potential height of support of this second candle.
  • the displacement of the rotary base 9 makes it possible both to modulate the position of the candle 3 and to vary the angular position of the height block 7.
  • the figure 2 illustrates, at a slightly different angle, a support device 30 similar to that of the pallet 20 of the figure 1 , the same elements being designated by the same references.
  • the height wedge 7, during the rotation of the rotary base 9, moves along a circular trajectory 17.
  • the carrier rod 8 is here positioned so as to remain in this path behind the wedge 7, especially when the shim 7 comes to cap the second candle 2.
  • the space between the first candle 1 and the second candle 2 remains clear over the entire height of the candles, and we can, depending on the needs, insert a portion of the casing of an engine.
  • the device 30 may comprise indexing elements, for example an indexing relief 18 visible on the figure 2 , designed for example to limit the rotation of the support 9 in a first direction of rotation.
  • the indexing element 18 may for example form an angular stop blocking the base 9 in rotation.
  • indexing elements for example a pin 28, also visible on the figure 2 .
  • One or more indexing holes through the base 9 may be provided for the pin 28, and one or more indexing holes 29 passing through at least a portion of the height of the base 11.
  • An elastic holding device 19 may be provided to press the rotary base 9 against the fixed base 11, and thus ensure stability of the relative angular position enter the base 9 and the base 11, even before the pin in place of the pin 28 .
  • the elastic holding device 19 may comprise a spring sized to be countered manually, for example by lifting the base 9 relative to the base 11.
  • the compression spring (not shown) may be arranged to exert a pressure spreading, depending on the vertical direction, the upper face 16 of the mobile base 9, relative to a bearing shoulder located above the base 9, for example integral axially with the first candle 1.
  • the figure 3 is a top view of the device of the figure 2 illustrating two positions taken successively by the mobile base 9, a first position represented in dotted lines, and in which the height wedge is in a position 7 'superimposed axially on the candle 2. It is found on the figure 3 elements common to Figures 1 and 2 the same elements being designated by the same references. In this first position, the third candle occupies a position 3 'which is compatible with the size of the engine designed to be supported by the candle 2 and raised. The pin 28 and one of the holes 29 are designed to block the base 9 in this first position.
  • a second position of the base 9 and elements attached thereto is shown in solid lines.
  • the position shown is a transient position, allowing, by continuing the rotation of the base, to arrive for example to the angular position indexed by the shim 18, for which the third candle 3 is adequately placed to support a model of motor to which this spatial configuration of the candles is adapted.
  • the height wedge 7 can be connected to the base 9 by a tab extending radially between the first candle and the wedge, or at least intercepting, higher than at the level of the base 9 itself, the radial plane passing through the axes of the two candles.
  • the rotating base 9 can support a shim height 7 without carrying a third candle 3, or can instead support two or more candles.
  • the shapes of the upper parts of the candles may vary depending on the support zones provided on the engines to be supported, and may comprise for example flat supports, blades, dihedrons, pawns.
  • the shape of the hold can be provided to preserve the geometry of the support zone, or to modify the geometry of the support zone.
  • the support device makes it possible to increase the versatility of the assembly pallets, and makes it possible to use each pallet for more varied engine configurations to be assembled.
  • the device allows to adapt at an affordable cost, an existing pallet, by adding a new support configuration adapted to an engine model not originally planned.
  • the device makes it possible to put into production a new engine geometry by reusing already available tools.
  • the device according to the invention makes it possible to reduce the manufacturing cost associated with the production tools, to limit the overall size of the production tools of a factory, and to reduce the number of references to be managed with regard to the tools.
