Definitions
- the present invention belongs to the field of machine tools for machining parts to be held fixed during machining, in particular for large parts. More particularly, the invention relates to a fixed support for parts that makes it possible to prepare a part in masked time during the machining of another part.
- the machine tool has a fixed horizontal table adapted to the dimensions of the workpiece and held on a base of high rigidity.
- the piece is fixed on an upper face of the table.
- the machine tool comprises a mobile gantry, having the shape of an inverted U, carrying one or more machining heads positioned above the workpiece.
- a known solution is to work in masked time, that is to say to perform an operation of preparing parts on parts to be machined while the machine tool performs an operation. machining on other parts.
- This preparation in masked time avoids immobilizing the gantry during the preparation operations but requires in return to double at least the necessary length of the machining table and therefore occupy in the workshop a much ground surface more important. For example, for parts usually measuring a few meters, these Machine tools can reach several tens of meters in length to allow work in masked time.
- the present invention proposes a fixed support for parts for machine tools which comprises a table frame and a table having a first face capable of holding a first workpiece, said first face being fixedly positioned above a machining carriage and said first piece being stationary during machining.
- the table further comprises a second face adapted to similarly hold a second workpiece.
- the table is reversible so as to make interchangeable the two faces of said table.
- the table is positioned in the table frame having an aperture adapted to the dimensions of the table, such that the first piece is machined on one side and the second piece is prepared on the other side.
- the part preparation operation performed in masked time on the other side of the table makes it possible not to increase the floor area of the machine tool.
- the support comprises means for fixing the table on the table frame in order to immobilize the table on said table frame during the machining operation .
- Said fastening means may be flanges and or locks and or locking keys and or fulcrums.
- the table in order to facilitate the operations of turning the table, has an axis of rotation substantially parallel to the two faces of the table and mounted on bearings fixed on said table.
- the cross section of the opening of the frame, perpendicular to the axis of rotation is a arc of a circle centered on said axis.
- the support also comprises sealing means between the table and the table frame.
- sealing means between the table and the table frame.
- FIG. 1a a schematic perspective view of a workpiece support according to the invention
- FIG. 3a a schematic perspective view of a support of parts comprising a reversible table pivoting according to the invention
- Figure 3b a longitudinal section of the same support parts having a reversible table pivoting according to the invention
- Figure 3d a cross section of a support parts with a reversible table pivoting according to the invention, illustrating an example of section of the opening of the table frame.
- a fixed support 1 for parts for machine tools comprises a table frame 3 and a table 2 comprising: a first face 21, able to maintain at a fixed position a workpiece 211,
- the support 1 is substantially horizontal, and the table 2 is of length at least equal to the length of the largest workpiece.
- the support 1 has sufficient rigidity to guarantee the stability of the table when machining parts.
- holding means 4 such as for example flanges, are arranged in a conventional manner on each of the faces 21, 22 of the table 2.
- the table 2 is held on the table frame 3.
- Said table frame is constructed with sufficient rigidity to support said table and the parts 211, 221.
- the support 1 is placed so that the workpiece can be machined by a mobile machining device, advantageously placed below said support.
- the support 1 is itself fixed to two vertical walls 5 which maintain it at the desired constant height relative to the machining device.
- the table 2 and the table frame 3 are made integral, in particular during the machining operations, so that the piece 211 during machining is perfectly immobilized.
- a method consists, for example, in using a table frame 3 having a thickness d greater than the thickness e of the table.
- the table frame 3 comprises an opening, comprising abutment points of oblique cross-section, able to receive a table 2 having ends 23 of triangular cross-section, complementary to each other. to the section of the opening.
- the table 2 rests on a frame rim 31 or overflowing elements towards the inside of the opening accommodating the table.
- fixing means 7 such as flanges or bolts, are arranged to fix the table on the table frame.
- a key system (no shown), can be used to position and immobilize the table on the table frame.
- the table frame 3, the ends of the table 23 and the fixing means 7 of said table on said frame are arranged so that, in a fixed position, the first face 21 corresponds to a lower face of the table. 2 and the second face 22 corresponds to an upper face of the table and in a second position, the first face 21 is the upper face of the table and the second face 22 the lower face.
- This masked operation can be performed directly on the support without increasing the floor area of the machine tool in the workshop.
- the face of the table used is advantageously the face in the upper position because it requires the intervention of operators and the piece, when not yet maintained by flanges, is not likely to fall when placed on Table.
- the upper face of the table is preferably substantially at or above the table frame.
- a not shown lifting means can be used.
- the table 2 is raised out of the frame of table 3, then, in a second step, it is returned, and finally, in a third step, it is repositioned in the frame 3 to be again immobilized.
- the table 2 pivots about an axis of rotation 24, corresponding substantially to its longitudinal axis.
- the axis of rotation 24 is preferably mounted on bearings and the rotational movement can possibly be ensured by means of motors or cylinders 25 located for example at both ends 26 of said table.
- the table 2 is held in said fixed position by locking means 8 fixed to the table frame 3.
- Said locking means in a first position, hold the table 2 in a fixed working position, and in a second position, release the table 2 so that said table can rotate.
- the reversal of the position between the two faces 21, 22 is effected by a rotation of the table 2 by 180 ° about the axis 24.
- the table frame 3 has an opening whose size allows the rotation of the table 2 about the axis 24 without lifting said table.
- a space 9 is created between the ends 23 of said table and the table frame 4, as shown in Figure 3c.
- the space is advantageously closed by a cover gasket 10 placed around the table 1 before the start of the machining operation.
- the section of the opening of the table frame 4 perpendicular to the axis of rotation corresponds to an arc of a circle centered on the axis of rotation 24. This configuration makes it possible to limit the space 9 between the ends 23 of the table and the opening of the table frame.
- the invention thus makes it possible to obtain a fixed support for machine tool parts for machining workpieces that must be kept motionless during machining, making it possible to prepare a part in masked time during the machining of another workpiece without multiplying the workpiece. floor occupation area.
