Definitions
- the present invention relates to a lathe provided with means for the manipulation of the pieces to be machined, in the sense of bringing the pieces to the place at the machining site and removing them after machining, for replacement with another new piece to be machined , providing in such aspects a functionality that makes the use of the lathe remarkably advantageous for its application.
- An embodiment known in this regard is the provision of a mobile gantry, with driving and handling means, mounted on travel guides located adjacent to the lathe.
- This solution is complicated and bulky, due to the structure required by the conveyor and its functional individuality with means independent of the lathe.
- the Spanish Patent P 0465162 discloses a loader-warehouse of parts, which is accessoryly attachable to a lathe, providing that loader-warehouse of means to be able to place the 25 pieces successively in an outlet, where they can be picked up by a manipulator swingarm mounted on a shaft. This solution is in turn complicated and expensive, and does not satisfactorily solve the process.
- EP 0539837 discloses an arrangement of two manipulators, one to place the pieces to be machined and the other to remove them from the lathe once mechanized; resulting in this complicated solution and expensive, both for installation and operation.
- Solutions are also known that arrange the head and the counterpoint of the lathe in a common carriage movable to a place of collection and deposit of the pieces, so that by means of the separation or approximation of the head and the counterpoint, on said carriage * carrier of the
- the application parts are taken and left, moving between the place of collection or deposit and the place of machining, by moving the car.
- Patent DE 19911156 includes a solution in which the head and the counterpoint of the lathe are incorporated in separate carriages, which * are movable on horizontal and vertical guides to move the application parts between the machining place and the point of collection or deposit.
- the head is also incorporated on a mobile car, which entails the same disadvantages of the previous solution for high powers, since the actuator means of the head must be included in the corresponding mobile car. And on the other hand, due to the mobile arrangement of the carriages upwards, the tool turret is located below the machining area, so that the chips and coolants of the machining fall on said turret.
- This lathe object of the invention comprises a bench that determines a structure on which the lathe head is fixedly fixed, in vertical arrangement or in horizontal arrangement, at least one carrier carrying a manipulator being mounted on said frame structure to move the pieces to be machined to the machining position and remove them after the operation.
- the carriage carrying the manipulator is arranged in a longitudinal displacement assembly on the structure of the lathe bed, said carriage itself determining also a transverse displacement arrangement and a vertical displacement arrangement of the assembly that the manipulator comprises.
- the disposition of the manipulator itself on the carrier car includes an assembly that allows turning and tilting movements of the manipulator in an embodiment with two operating claws, by means of which it can independently take both parts, in the work function.
- the manipulator can be moved and moved to pick up the parts to be machined from a feeder warehouse and take them to the machining position on the lathe, as well as remove them after machining for unloading in an output pickup; allowing the double claw of the manipulator to remove a piece and leave another by means of a single movement operation, both in the machining place and in the place of feeding and unloading, which speeds up the replacement of the application parts in the lathe, reducing to minimum machining downtime for replacement of parts.
- the drive for machining can be established with means incorporated in the head itself or from means located independently on the bed with a transmission from them to the head, which allows to use means, actuators of any power, without this requiring the head clamping means to be oversized.
- the head and tailstock (if it exists) can be conventional, with the possibility, for example, of incorporating bearings of 120 millimeters in diameter or more, without forcing the structure to be oversized. And also, parts can be manipulated and machined, for example from 10 to 500 millimeters in diameter and 200 to 2000 millimeters in length, without having to modify the structure of the lathe.
- the turret tool holder of the lathe can go for its part incorporated in the same carrier carriage of the manipulator of the parts, which reduces the actuator means necessary for the movement of both elements; going that mobile assembly over the machining area, which prevents the fall of chips and coolants from machining on the tool turret.
- the manipulator of the pieces can however also go in a car independent of the turret tool holder, which facilitates a reduction of the inactive machining times, since the manipulator can move and perform the operations of its function during the machining. It is also possible to have more than one tool turret, on the same movement guides of the carriage of the parts manipulator, to carry out simultaneous machining operations.
- a larger head can be arranged, without having to oversize the winch structure.
- the subjection of the pieces to mechanise is more rigid than with the solutions of moving head.
- the load capacity is greater than with the solutions in which the head acts as a manipulator.
- the tool holder turret undergoes positioning variations in the first passes of the machining, which are of greater roughing, but the position is corrected by the recovery of the material, so that in the last passes of lesser roughing the machining is performed with precision, thus obtaining a more perfect machining than with the mobile head solutions, in which the piece undergoes variations of positioning in the passes of greater roughing, maintaining the uncorrected position until the end of the machining
- said lathe of the invention certainly results from very advantageous features, acquiring its own life and preferential character with respect to known lathes of the same application.
- Figure 1 shows in schematic perspective an embodiment of the recommended lathe with vertical head.
- Figure 2 shows an embodiment of the lathe with a horizontal head driven by transmission from independent means thereof.
- Figure 3 is a perspective of the lathe according to an embodiment with horizontal head provided with drive means incorporated therein.
- Figure 4 is an enlarged detail in perspective of the double claw manipulator of the winch.
- Figures 5 to 8 are schemes of various possibilities, not limiting, of practical embodiments of the lathe with the vertical head, within the framework of the invention.
- Figures 9 to 13 show respective schemes of various possibilities, not limiting, of practical embodiments of the lathe with the horizontal head.
- the lathe object of the invention consists of a bench that determines a structure (1), on which the head (2) for securing and rotating drive of the parts (3) to be machined is incorporated in fixed arrangement.
- the head (2) can be vertical, as in figure (1), for machining operation with the application parts (3) arranged on it; but it can also be horizontal, as in Figures 2 and 3, in this case the pieces (3) being arranged for machining between the head (2) and a corresponding counterpoint (4) or other complementary fastening means.
- the structure (1) of the machine bed it determines in the upper part longitudinal guides (5), on which at least one carriage (6) is incorporated in mobile assembly, in which a manipulator (7) is arranged to bring the parts (3) to the machining position and remove them after machining.
- the manipulator (7) is provided with two operating claws (7.1 and 7.2), going in a tilting arrangement that allows to place said claws (7.1 and 7.2 ) indistinctly in a position to pick up the pieces (3) and in a standby position empty or holding a piece (3).
- the manipulator (7) is incorporated in a support (8), by means of which it can be moved vertically on the carriage (6) along some guides (9) for mounting said support (8); while the carriage (6) itself is arranged on a base (10), in guided assembly with respect to transverse guides (11) of said base (10), with the possibility therefore to move transversely on it.
- the manipulator (7) is capable of making all the necessary movements for the collection of the parts (3) to be machined, from a feeder (12) , to take them to the placement in the head (2) for machining; as well as removing the pieces (3) already machined, from the head (2), to take them to the place of unloading.
- the head (7) also allows a piece (3) to be machined, up to 'the head (2), for example with the claw (7.1) and using the claw (7.2) remove the previously machined part (3) from the head (2), which considerably reduces the replacement time of the parts (3), since the incorporation of a new part (3) to be machined and Withdrawal of the machining above is done by the same operation of manipulator movement (7).
- the collection and unloading of the pieces (3) can be carried out by means of the same operation of movement of the manipulator (7), if the unloading of the mechanized pieces (3) is done in the own place of collection of the pieces (3) to be machined or in an adjacent place.
- the tool turret (13) of the lathe can be incorporated in the same carriage (6) carrying the manipulator (7), whereby, only the actuator means of said carriage (6) can handle the movements of the manipulator (7) place and remove the parts (3) with respect to the head (2), as well as the movements of the tool turret (13) for machining.
- the incorporation of the tool turret (13) into an independent carriage (14) is provided, arranged on the same guides (5) of the upper part of the structure (1) of the bed, with which the manipulator ( 7) and the tool turret (13) can be used independently simultaneously, being able to unload a machined part (3) and pick up another new part (3) to be machined, while machining of a third piece (3) arranged in the head (2), thereby increasing the productivity of the lathe, since the inoperative machining times are minimized.
- Figures 5 to 8 show schematically different possibilities of the practical arrangement of the lathe, in the embodiment with the vertical head (2); representing Figure 5 an arrangement with a car (6) in which is incorporated in a manipulator (7) and the tool turret (13), Figure 6 an arrangement with a carriage (6) carrying a manipulator (7) and another independent carriage (14) carrying the tool turret (13), figure 7 an arrangement with a carriage (6) carrying a manipulator (7) together with a tool turret (13) and another independent carriage (14) carrying a second tool turret (13), and figure 8 an arrangement with two heads (2) and above two carriages (14) carrying two tool turrets (13) and an intermediate carriage (6) with two integrated manipulators (7) in a double manipulator.
- Figures 9 to 13 show in turn different possibilities of the practical realization of the lathe with the horizontal head (2), representing figures 9, 10 and 11 respective arrangements similar to those of Figures 5, 6 and 7, in this embodiment , while Figure 12 is an arrangement like that of Figure 9 but with two heads (2) facing each other, instead of a head (2) and a counterpoint (4), figure 13 corresponding to an arrangement similar to that of figure 8, in this embodiment.
- the assembly of the tool turret (13) and the counterpoint (4) can also be replaced by a machining unit that is complemented with the head (2) for fixing the parts (3) for machining, or with the corresponding mooring and fixing means.
- a complementary tool turret (13) can also be incorporated in a carriage arranged below the machining area, which allows complementary machining passes to be carried out virtually simultaneously with each pass that It is done with the means of the upper part, allowing to reduce the time to be used in the machining of the pieces (3).
- the fixed arrangement of the head (2) ensures in any case an immobility that keeps the clamping of the parts (3) stable in the machining, allowing to achieve a machining of great perfection.
- Said fixed arrangement of the head (2) also allows the means for adjusting the rotary drive of the plate thereof, can be integrated into the head (2), as in the embodiment of Figure 3, or have independent actuating means ( 15), to establish, by means of a transmission (16), the drive of the head (2), as in the embodiment of Figure 2.
