Definitions
- the invention relates to a vertical lathe with two or more spindles according to the preamble of claims 1 and 7.
- Workpiece holder, workpiece machining and workpiece transfer to the second spindle can be moved.
- the second spindle cannot be moved in the horizontal direction.
- the tool holder belonging to the second spindle can be moved together with a gripper hand for transporting the workpiece from the machining position to the transfer position to a workpiece conveyor belt on the same guideway as the first spindle.
- the first spindle has to travel relatively long distances and thus has higher loading times than the second spindle, in which, for. B. the workpiece feed process with the help of first spindle and the workpiece removal can take place simultaneously with the help of the gripper hand.
- the invention has for its object to provide a generic vertical lathe in which the aforementioned problems do not exist even with larger workpieces.
- the headstock in their working position are each in their own, relative to the other at a joint and vibration-isolated machine bed and that the two machine beds for the transport of the workpieces can be connected from one to the other headstock at least in the area of the guideways and / or for the transport of the two machine beds. It is therefore possible that the two machine beds are firmly screwed together for transportation and that the entire vertical lathe can thus be transported as a unit. After normal assembly on a stationary base, the screw connection is then at least loosened to such an extent that the two machine beds are vibration-isolated from one another.
- an elastic vibration insulation layer in the area of the parting line.
- B from prestressed elastomer sheets with a thickness of 10 to 30 mm, preferably about 15 mm. With the help of this prestress, sufficient sealing and vibration isolation are achieved in the area of the parting line. It is important that during the Processing a metallic decoupling at least so far that no vibrations can be transferred from one machine bed to the other.
- the guideway is also interrupted and metallically decoupled, so that vibration isolation is also present in this area.
- the detachable connection between the two guideways can consist of conical connecting pieces which are adjustable relative to corresponding guide strips.
- a sliding plate can be firmly connected to the one guideway in the transition area and can be sufficiently firmly connected to the other guideway with the aid of an actuating device for the time when the headstock is passed over.
- At least one cylinder acting transversely to the guideway can serve as the actuating device for releasing and connecting the sliding plate.
- the second headstock can also be moved on a guideway in the X direction from a workpiece receiving position via a machining position under the workpiece carrier to a workpiece transfer position.
- both headstocks have to travel approximately the same distances, so that the same cycle times result with the same machining times. This avoids waiting times, especially when transferring from the first to the second headstock.
- adjustability in the X direction can be dispensed with. It is sufficient if the tool carrier or the second one can be delivered
- Headstock in the Z direction is given. It has proven to be cheap here proven to make a decoupling between the gripper hand and the second tool carrier in such a way that the gripper hand can be moved in the X and Z directions so that it can bring the workpiece after the second machining from the second headstock to the workpiece transport device.
- FIG. 1 shows a front view of a vertical
- FIG. 2 shows an enlarged section in the transition region of the horizontally running guideway
- FIG. 3 shows the arrangement according to FIG. 2 in a vertical section
- Figure 4 shows the arrangement of Figure 2 or 3 in plan view.
- (1) denotes the entire housing or machine bed, the machine bed (1a) being provided for the first machining and the machine bed (1b) for the second machining of the workpiece (6) .
- a parting line (22) with an insulating or damping layer made of pre-stressed elastomer material.
- the two machine beds (1a, 1b) can be firmly connected to one another via the screw connections (23) for transporting the entire vertical lathe. After assembling the two machine beds (1a, 1b) on the stationary base, the screw connections (23) are loosened to such an extent that vibration isolation exists between the two machine beds.
- the headstock (4) is moved with the help of an X-slide (3) on the horizontal guideways (2) from a transfer position for the workpiece (6) above the workpiece transport device (9) to the workpiece take-up position (A) through the second headstock (A) 10) movable.
- the guideways (2) are in turn separated in the region of the parting line (23) in such a way that vibration isolation is ensured during processing by metallic decoupling.
- FIGS. 2 to 4 For the passage of the separation area by the X-slide (3), the releasable connection is shown in FIGS. 2 to 4.
- a plate (25) is then provided, which is partially slotted in the area of the parting line and is firmly connected to the guide track (2a) by means of the screws (24).
- the guide track (2b) is connected to the conical connecting piece (28) via the screws (24).
- the conical guide of the guide bar (27b) is pressed firmly against the conical connecting piece (28) using the hydraulic cylinder (30).
- this connection is released by separating the connecting pieces (31) and the guide bolts (29).
- the guide strips (27a) and (27b) are connected below the guide tracks (2a) and (2b) via the screws (26) to the legs of the plate (25), while the detachable connection between the guide pins (29) is located above the guide track. and the hydraulic cylinder (30).
- the chuck (5), the axis of rotation (7) of the headstock (4) and the tool holder (8) are also shown in a conventional manner.
- the height of the tool carrier (11) can be adjusted together with the gripper hand (16) on the Z-slide (18) on guideways (17) arranged.
- the gripper hand (16) can also be moved horizontally with a device (21) between the workpiece transfer position (C) and the workpiece transport device (19).
- the Z-slide (18) is adjusted vertically by means of the hydraulic cylinder (20).
- the headstock (10) can be moved on horizontal guideways (12) between the workpiece receiving position (A), the machining position (B) and the workpiece transfer position (C).
- a spindle (13) is provided for this movability in a manner known per se.
- the axis of rotation (14) and the chuck (15) of the headstock (10) are shown in a manner known per se.
