Definitions
- Bench for machining elongate objects such as strips of marble and the like
- the present invention relates to a bench for machining elongate objects of marble and the like.
- the present invention provides a bench for machining elongate objects that comprises a generally boxlike body having a surface over which a portable profiling machine can be moved, and a side comprising means for holding strips or the like in position by means of a plurality of pneumatic suction inlets which, by the action of low pressure, hold the elongate object stably during its machining.
- the present invention also provides an element for supporting the workpiece and positioning it correctly, with the aid of a pair of graduated elements arranged for the repeatable adjustment of the position of the workpiece and for ensuring it is parallel with the upper surface of the machining bench.
- Figure 1 is a perspective view of the machining bench according to the present invention.
- Figure 2 is a perspective view of the machining bench shown in Figure 1 on which an elongate object or strip extending roughly the full length of the machining stroke is fixed for machining;
- Figures 3 and 4 are views similar to Figure 1 of the machining bench, on each of which are fixed workpieces with different proportions to those of the strip object shown in Figure 2;
- Figure 5 shows the same view of the machining bench of Figure 1, on which different types of strip object are fixed;
- Figure 6 is a side view of the machining bench according to the invention with parts removed to show the internal components
- Figure 7 is a side view of the machining bench according to the invention in conjunction with a typical profiling machine.
- the machining bench comprises a boxlike body 1 standing on feet 2, 3 and having an upper surface 4 over which a profiling machine can be moved, and a surface 5 against which the elongate objects or strips to be machined are leaned and on which they are retained.
- the surface 5 has a plurality of low- pressure pneumatic suction inlets 6, 7, 8, 9 running along the top close to the edge formed by surfaces 4 and 5.
- At the ends of the surface 5 are two grooved elements 10, 11 having slots 12 in which clamping pins 13, visible in Figure 6, can slide. These pins 13 are connected to levers 14, 15 for clamping in position a supporting bar 16 comprising a right-angled stiffening part 17.
- Parts 10, 11 are conveniently provided with a millimetric or other similar scale 18, 19 to provide a positioning reference with respect to the upper surface 4 of the supporting bar 16 on which the workpieces are rested.
- Figures 2 to 5 show the same view of the machining bench as in Figure 1, on which various types of elongate objects or strips are positioned and fixed for machining.
- Figure 2 shows the machining bench of the invention on which is positioned a strip object 20 of considerable longitudinal length
- Figure 3 shows the machining bench on which an elongate object or strip 21 of considerable extent both longitudinally and transversely is positioned.
- Figure 4 the workpiece 22 occupies only part of the maximum acceptable length of the elongate objects or strips for machining
- Figure 5 shows a number of different elongate strip objects 23, 24, 25 for machining, varying in type and longitudinal length, secured simultaneously to the same machining bench.
- Figure 6 shows the low-pressure pneumatic suction inlets 6, 7, 8, 9 connected by tubes 26, 27, 28, 29. Each of these tubes has its own on-off valve 30, 31, 32, 33 which come together at 34 in a vacuum reservoir 35 well known in the art.
- the reservoir 35 is connected by a tube 36 to a pneumatic vacuum generator employing a compressed-air ejector operating by the Venturi effect, marked 37 and well known per se, so it will not be described in further detail.
- the vacuum generator 37 is connected via a valve 38 to a compressed air admission connector 39.
- the reservoir 35 can, when necessary, be pressurized with compressed air through a connector 40.
- the reservoir 35 is also connected to a valve 41 for discharging water or other liquids, which may perhaps collect in it as a consequence of the grinding wheel operations, which are usually carried out with the aid of lubricating coolants, preferably water-based, which can be sucked in by the suction elements 6, 7, 8, 9.
- valves 30, 31, 32, 33 can be operated selectively to suit the dimensions of the work material in the longitudinal direction.
- vacuum reservoir 35 helps in equalizing the suction action of the suction elements 6, 7, 8, 9.
- machining bench according to the invention is shown in combination with a profiling machine 42 which uses a grinding wheel 43 to machine a generic strip 44 while the latter is held in position.
- a profiling machine 42 which uses a grinding wheel 43 to machine a generic strip 44 while the latter is held in position.
