Definitions

  • the invention relates to a universal precision vice for a machine tool.
  • the invention is based on the object Precision vice for machining workpieces in to propose a machine tool that is universal can be used and therefore the clamping of the workpiece both from the outside and from the inside, the simultaneous Clamping two workpieces and one concentric and self-centering clamping of the workpiece allowed and in addition the clamping process both conventionally with the help of mechanical means too via hydraulic, pneumatic or electrical systems can be done.
  • SU-614935 is a universal precision vice become known for a machine tool that consists of a There is a U-shaped body, the movable carriage has, which are provided with interchangeable jaws and can be driven via a threaded spindle.
  • the well-known vice is particularly lacking precision guides in the form of guide grooves and ground Sliding surfaces that slide the sled body with precision slidable.
  • the object of the invention is achieved with a universal precision vice solved for a machine tool, that consists of a basic body that with interchangeable jaws equipped precision slides that Have threaded holes with which a right-handed Thread section or a left-hand thread section one, near the bottom of the body provided drive spindle is engaged, and between the threaded sections of the drive spindle peripheral groove connected with a stop is provided, and the vice thereby is marked on the opposite sides of each leg of the U-shaped Cross-section of a basic body Guide groove is provided, and in the guide grooves Precision slides are slidably mounted with the circumferential groove has fork-shaped ends of cylindrical Clamping bodies can be engaged or disengaged are, and the cylindrical clamping body slidable in Bores made in the legs of the U-shaped body are incorporated, that the axes of the Bores aligned transversely to the axis of the drive spindle are, and the free ends of the legs of the U-shaped Body support and sliding planes for the mobile Form jaws with
  • Such a vice for a machine tool is a universal vise that can be used for different purposes Can easily adjust clamping processes.
  • an im body consisting of a cuboid after the The modular principle can be manufactured that is easy to handle and is in the machine tool in any desired Position, i.e. in horizontal, vertical or inclined Position, can be installed.
  • the invention also has the advantage that all Components of the precision vice with each other are interchangeable, so these parts are either easy replace or easily add additional components, without the precision vice from the machine and to dismantle.
  • the precision vice proposed by the invention can be achieved easily with auxiliary devices of an automated drive, i.e. the Vice is simple with electric motors, Hydraulic motors or pneumatic motors for driving the spindle provided inside the vise can be equipped.
  • the basic body as a simple prismatic element is designed to facilitate its Processing, especially with regard to the Grinding process of the precision guides, in which the sliding carriage are arranged as well as the Finishing of the flat sliding guides on the Leg ends of the U-shaped body are formed.
  • the one shown in FIG. 1 and overall with 1 designated vise consists of a body 2, the has a substantially U-shaped cross section.
  • the body of the vice 1 consists of a Base body 3, from which two legs 4 and 5 protrude.
  • the guides 6, 7 and 8, 9 are extremely precise edited, namely the guides 6, 7, 8 and 9 hardened and ground in an advantageous manner.
  • the guides 6 and 7 take lateral sliding projections 10, 11, 12 and 13 on the sled 14 and 15 are connected in one piece.
  • annular beads 24 provided that limit a groove 25, also points the drive spindle 21 on both sides of the groove 25 thread 26 and 27 on.
  • the thread 26 is right-handed, during the Thread 27 is left-handed (or vice versa).
  • the threads 26 and 27 can be with the threaded holes Connect 18 and 19, the left-handed in the projections 16 and 17 of the carriage 14 and 15 are executed.
  • the Carriages 14 and 15 can be replaced with interchangeable jaws 30 and 31 can be equipped to match special application different clamping processes to enable.
  • the jaws 30 and 31 are advantageously with With the help of screws 32 and 33 on the slide 14 and 15 attached.
  • the body 2 of the vice 1 has one in the middle transverse through bore 34.
  • the axis of the Bore 34 is perpendicular to the longitudinal axis of the U-shaped Body arranged.
  • the clamping bodies 35 advantageously have the shape of cylinders, and the end facing the spindle 21 has the shape of a fork 36 to form a positive Connection between fork 36 and bead 24 and that in the Groove 25 formed in the center of the spindle 21.
  • each cylindrical clamping body 35 penetrates also a continuous threaded hole, which one over a key 42 rotatable clamping screw 41 for Tightening or for releasing the clamping body 35.
  • the bearing block 50 is at the bottom of the body 2 of the Vice 1 attached.
  • adjustment holes 51 are formed in the area thereof a bracket 52 can be positioned and fixed, the into the groove 25 delimited by the beads 24 intervenes.
  • the bracket 52 is in the range of a bore 51st arranged, thereby allowing the middle of the Drive spindle 21 to the body 2 of the vice 1 too determine.
  • This device also includes a number Pins 53 with a square cross section. It's a job of these pins the (after the attachment of the bracket 52) on one or space remaining on either side of the bracket 52 to fill.
  • each hole 150 takes a grub screw 151, which is by means of a Tool 39, 42 can be operated.
  • the flat guides 8 and 9 advantageously have Bores 70 and transverse grooves 71 so that the clamping jaws precisely positioned with the help of the transverse grooves and with corresponding screws inserted into the bores 70 can be attached so that e.g. in the middle of Flat guides 8 and 9 fixed abutments for special Let applications be created.
  • FIGS. 7, 8 and 9 and in FIGS. 10 to 17 are some possible embodiments of the Vice according to the invention shown.
  • Figure 18 shows the base body 2 of the vice 1 in perspective view. It is also the end section 22 the drive spindle visible inside the body 2 is in operative connection with the slides 14 and 15.
  • the structure of the base body 2 of the vice 1 is like this that several vices 1 let them be put together one after the other and within the Provided body of the assembled vices Drive spindles can be driven separately or together can.
  • Figure 19 shows how one end of the body 2 with a Drive means 61, e.g. connected to an electric motor can be. Since the spindle 21 has polygonal ends, which form the spindle ends 22, 23, the drive means on both the right and left sides of the Vise body 2 are arranged.
  • FIG. 20 The body 2 of the vice 1 shown in FIG. 20 can be operated with a hydraulic drive means 62 connect and finally Figure 21 shows one Vice 1, the body of which with a mechanical Device 63 is connected so that the drive spindle of the vice 1 operated by mechanical means can be, in the case shown in a Angular position to the axis of the vice 1 arranged are, with the ends of the drive spindle a clutch 64 is connected, which can be rotated via a sleeve 65, into which a key, e.g. engage an Allen key can.
  • a clutch 64 is connected, which can be rotated via a sleeve 65, into which a key, e.g. engage an Allen key can.
  • the body 102 forming the group of vices 101 is provided with through holes 140 which the Attaching the multiple vice 101, for example allow a plate 141, for example by a Standard palette is formed that one Machining center can be fed automatically.
