Definitions

  • the invention relates to a spinning machine according to the preamble of claim 1.
  • the invention is therefore based on the object of reducing the performance of spinning machines by reducing the set-up times.
  • the pivotability according to the invention must be 90 ° or more.
  • the pivot axis of the tailstock he has a swivel range of 120 ° to 180 ° as the most practical solution.
  • the tailstock with its quill is swiveled to the periphery of the spinning machine. There the finished workpiece is removed from the quill, a new workpiece is placed on the quill and swiveled back with it. Swiveling out the sleeve with the workpiece placed on it reduces the risk for the operator from rotating parts of the machine, since his field of operation is at a safe distance from the spindle and the tools.
  • the quill is easily accessible both for an operator and for other automation devices.
  • the better accessibility makes it easier to load the machine, as you can see at a glance whether the workpiece is correctly seated on the quill;
  • the free quill can be loaded faster than with a crane.
  • the quill is pivotable relative to the tailstock slide which can be moved in the direction of the mirror axis.
  • two quills can be provided on a tailstock. These two quills are mounted on a common support which is pivotally mounted on the tailstock slide which can be moved in the direction of the spindle axis. In the working or loading position, the two quills are preferably both aligned with the spindle axis.
  • the spindle axis of the spinning machine and the swivel axis of its tailstock or the quills arranged on it are in one plane.
  • a further embodiment of the invention is given in claim 3.
  • 2 tailstocks or quills these are arranged offset by 180 ° on the pivotable carrier of the tailstock.
  • 3 quills on the carrier are arranged offset by 120 °.
  • the loading and unloading station can be separated.
  • Three quills can be particularly advantageous for short working hours. While the machine is working and the first quill presses the workpiece against the spindle, the finished workpiece is removed from the second quill and at the same time a new workpiece is placed on the third quill.
  • the use of three quills also has the advantage that the loading and unloading stations are always arranged between the machine bed itself and the supports.
  • the sleeves with the workpieces arranged thereon can be swiveled quickly.
  • the embodiment of the invention is provided according to claim 4.
  • the embodiment of the invention is preferably provided according to claim 5.
  • Grippers are primarily used, which clamp the workpiece like a pipe expander.
  • hooks can be provided at the ends of the grippers which hold the workpiece in a form-fitting manner on the sleeve.
  • a further embodiment of the invention is given in claim 6.
  • the earliest possible start of the rotary movement is postponed, since large workpieces have to be pulled further out of the working area of the machine before they can be swiveled with the sleeve.
  • the embodiment of the invention according to claim 6 takes this fact into account to a special degree.
  • the configuration according to claim 8 is used according to the invention. It is advantageous here that the finished workpiece does not have to be removed between two tools.
  • the spinning machine (1) shown in Figure 1 consists of a machine bed (11) on which a headstock (6), a tailstock (8) and four supports (2, 3, 4 and 5) are arranged.
  • the spinning machine has a drive (28) for the main spindle (38) in the headstock (6).
  • the drives for the supports are not shown.
  • On the spindle a conical tool (29) is attached.
  • a partially machined workpiece (39) is clamped in the clamping direction of the spindle axis (7). This workpiece is deformed without cutting by 4 pressure rollers (40, 41, 42, 43) that work in different planes.
  • the tailstock (8) can be moved in the direction of the arrow (44) and can be pivoted through 180 ° in the direction of the arrow (45).
  • the tailstock has a second quill (12) aligned with the spindle axis (7).
  • the sleeve (9) is in the working position (10), the sleeve (12) is in the loading or unloading position. In the loading position, the sleeve (12) is located on the periphery of the machine (1) or the machine bed (11).
  • the pivot axis of the tailstock and the spindle axes (7), as well as the quill axes lie in a plane that goes perpendicularly through the drawing plane of Figure 1.
  • the design of the spinning machine can be provided according to the illustration in FIG. 2 with 3 quills (13, 14, 15), these together on the tailstock (16) are arranged.
  • this version offers the advantage that loading and unloading can take place at different points at the same time. This reduces the set-up time per workpiece.
  • the sleeve (14) is in the unloading position and shows a finished workpiece (46).
  • a new circular blank (47) is already clamped onto the quill (15) and is pivoted into the working space (48) of the machine at the next work cycle.
  • the pivoting of the tailstock requires a special pivoting and locking device, as shown in FIG. 3, so that the necessary tolerances for the positional fixation of the workpiece can be carried out safely taking into account the high forces to be transmitted.
  • the tailstock in Figure 3 consists of a swiveling upper part (47) which has end teeth (31) on its bottom surface and engages with a large central sleeve-shaped pin (48) in the lower part (49) of the tailstock (8).
  • a large central sleeve-shaped pin (48) in the lower part (49) of the tailstock (8) At the bottom of the pin there is an axially displaceable worm wheel (37) which is in engagement with a worm (34). This is held in the non-swiveling lower part (49) of the tailstock (8) in bearing blocks (35, 36).
  • the worm is driven by a motor (22).
  • the swiveling upper part (47) of the tailstock is raised by a double-acting cylinder (33) to change the swivel position and then turned by the swivel device (22, 34, 37) by 180 °. After completing this turn, the upper part (47) is pulled by the double-acting cylinder (37) against the non-pivotable lower part (49).
  • the many stops (24) formed by the spur toothing (31) ensure permanent, precise mounting of the quills.
  • the tailstock (8) of the cylinder (23) on the machine bed (11) is slid away from the work area according to arrow (50) and as soon as there is sufficient swiveling without hindrance from the supports, the swiveling movement takes place, after which At the end the tailstock returns.
  • the finished workpiece (51) can now be removed while the new round blank (52) is already being processed.
  • FIG. 3 shows the arrangement of sub-tools on the quills, as is provided according to the invention when manufacturing vehicle wheels.
  • FIG. 4 shows how a workpiece (53) is fastened in the quill in order to avoid being thrown away during the swiveling movement or during the translatory movement.
  • the rotating sleeve (9) is provided with a clamping device (54) which holds and aligns the workpiece (53) thereon. Clamping and alignment are carried out by grippers (17, 18) which grip the workpiece, in the case shown a circular blank with a central bore (64), and clamp it with their clamping surfaces (20, 21) outwards in the bore (64) of the blank.
  • the levers (20, 21) have bevelled backs (55, 56) which are controlled radially by an axially movable cone (57).
  • the spreading movement is carried out by springs (58), the opening movement takes place by means of an axially movable plunger (59) which, in conjunction with springs (60, 61) acting in the radial direction, causes the grippers to move together and thus a change of the workpiece ( 53) allowed.
  • Hooks (62, 63) which engage behind the workpiece (53) through its bore (64), are provided.
  • the clamping device (54) is installed in a part tool (27) fastened to the sleeve (9). The tool rotates with the quill (9).
