Abstract
A fixture for drilling sheets of fragile material is connectable to a movable machining head having a supporting structure and a rotary member, and includes a supporting frame, a shank for connecting the supporting frame to the supporting structure, and a first and at least a second powered spindle for a first and, respectively, a second drilling tool and extending in opposite directions with respect to the supporting frame; the spindles being rotated about respective axes parallel to each other by a transmission, an input member of which is connected to the rotary member of the machining head.
Description
- The present invention relates to a fixture for drilling sheets of fragile material, in particular, sheets of glass.
- Sheets of glass, to which the following description refers purely by way of a non-limiting example, are drilled on machines comprising a spindle fitted with a drill bit, which is pushed against and fed through the sheet to form dead or through holes. When drilling through holes, the bit, as it comes out on the opposite side, normally splinters the sheet, so that one of the edges of the through hole is discontinuous and normally “jagged”. As a result, the drilled sheet cannot be tempered, as required in certain applications, such as glass doors, in that the sheet would shatter immediately on insertion inside the furnace.
- To overcome the above drawback, sheets for tempering are drilled using special drilling machines comprising a number of rotary spindles, each fitted with a drill bit, and which rotate and move independently of one another. To drill each hole, a dead hole is first drilled by a first bit advanced a given distance depending on, and normally equal to less than half, the sheet thickness; the first bit is then withdrawn; and a second bit is advanced from the opposite side of the sheet until it breaks through the dead hole to form the through hole.
- Though preventing splintering of the sheet around the through hole, the above drilling method calls for two drilling heads, and, above all, for a drilling machine with independent heads, which is used solely for drilling and is not always available in conventional sheetworking stations.
- It is an object of the present invention to provide a fixture designed to provide a straightforward, low-cost solution to the above problem, and which, in particular, provides for splinter-free drilling using conventional sheetworking machines with a movable machining head.
- According to the present invention, there is provided a fixture for drilling sheets of fragile material, in particular sheets of glass, and which is connectable to a movable machining head comprising a supporting structure and a powered rotary member; the fixture being characterized by comprising a supporting frame; connecting means for connecting the supporting frame to the supporting structure of the machining head; a first and at least a second spindle for a first and a second drilling tool respectively, said spindles being connected to said supporting frame to rotate about respective axes parallel to each other, and being oriented in opposite directions with respect to the supporting frame, so that the cutting edges of the tools are located on opposite sides of the supporting frame; and motion transmission means comprising an input member connectable to said rotary member, and which transmit motion to both said first and said second spindle.
- A number of non-limiting embodiments of the invention will be described by way of example with reference to the accompanying drawings, in which:
- FIG. 1 shows a schematic side view of a preferred embodiment of the fixture according to the present invention fitted to a movable machining head;
- FIG. 2 is similar to, and shows a variation of a detail in, FIG. 1.
-
Number 1 in FIG. 1 indicates as a whole a movable machining head of a machine (not shown) for machining asheet 2 of fragile material, such as glass, stone, marble, granite, etc. Machininghead 1, which is known, comprises a supportingstructure 3, and a poweredrotary member 4 rotating insidestructure 3 about anaxis 5. - Machining
head 1 is fitted releasably with adrilling fixture 7 for drilling both dead and through holes insheet 2. With reference to FIG. 1,fixture 7 comprises a hollow supportingframe 10 elongated in alongitudinal direction 11 perpendicular toaxis 5; and a known connecting portion orshank 12, not described in detail, for connectinghollow frame 10 tostructure 3 ofmachining head 1.Frame 10 is bounded by two oppositelateral surfaces longitudinal end portions respective spindles respective axes 20 parallel toaxis 5 and perpendicular tolongitudinal direction 11.Spindles respective surfaces respective drilling tools cutting portions frame 10.Spindles frame 10, and comprises aninput shaft 23 extending through connectingshank 12 and connected in known manner torotary member 4 of machininghead 1 to transmit motion to bothspindles - In the FIG. 1 example,
end portions frame 10 are connected integrally to each other, so that the distance D between theaxes 20 of rotation ofspindles - In the FIG. 2 example,
end portions device 25 for adjusting the distance D between the axes ofspindles device 25 comprises a guide-slide coupling 26, and is a discrete adjusting device. Alternatively, adjustingdevice 25 is a continuous type, and is conveniently powered to permit any relative arrangement ofspindles transmission 22 also comprises a known, conveniently telescopic,adjustable transmission assembly 28 interposed betweenspindles - In actual use, machining
head 1 fitted withfixture 7 is first moved parallel towork sheet 2 to position one of the two drilling tools,e.g. tool 19 a, as required, and then movesframe 10 towardssheet 2 in a direction parallel toaxis 20 and by a given distance normally less than the thickness ofsheet 2 to form a dead hole 29 (FIG. 2). Once the dead hole is drilled, and still moving machininghead 1,tool 19 a is backed up and away fromsheet 2, andtool 18 a is first positioned perfectly coaxial with the axis ofhole 29, and is then advanced to form a throughhole 30. - By employing a
frame 10 supporting twotools fixture 7 described therefore provides for drilling through holes without splintering the sheet, and, above all, using an ordinary machine, which has a machining head with rotary member fitted selectively with different tools, each for performing a specific operation, e.g. grinding, etching, polishing, etc. - Clearly, changes may be made to
fixture 7 as described herein without, however, departing from the scope of the present invention. In particular,frame 10 and/orshank 12 for connection tomovable machining head 1 may be formed, otherwise than as shown by way of example; andspindles frame 10 in positions other than those shown, and may differ in number from that indicated by way of example.
