Definitions

  • the invention relates to a machine vise with a vise body, a fixed jaw arranged thereon and a jaw movable relative to it, for the adjustment of which a screw spindle is used, which is held in a spindle bearing so as to be rotatable and axially immovable with respect to the vise body, and which rests upon rotation of the spindle the screw spindle moves the spindle nut.
  • the invention has for its object to design a machine vice of the type mentioned so that bending stresses and pinches of the screw spindle in the spindle bearing and in the spindle nut are avoided even when the jaws - due to tolerances or by the type and force of the workpiece clamping , - should be offset and / or tilted against each other.
  • the spindle bearing is located on an abutment arranged on the fixed jaw and the spindle nut is located on a slide carrying the movable jaw, which is displaceably guided on the vice body parallel to a guide plane running through the axis of the screw spindle, and that the abutment on the fixed jaw and the spindle nut on the slide are rotatably mounted about mutually parallel axes which are perpendicular to the axis of the screw spindle and on the guide plane of the slide.
  • the rotatable mounting of the abutment on the fixed jaw and the spindle nut on the slide ensures that the spindle bearing and the spindle nut can each adjust their own axis to the axis of the screw spindle, regardless of the respective setting of the jaws relative to each other and relative to the screw spindle. Pinches of the screw spindle in the spindle bearing and / or in the spindle nut are therefore reliably avoided.
  • the frictional connection of the jaws via the abutment on the one hand or the slide on the other hand is directly through the Abutment closed with the slide connecting screw, so that the vice body itself remains largely relieved of the clamping forces.
  • the abutment which is also guided in the vice body parallel to the guide plane of the slide, has a bearing journal which is coaxial with its axis of rotation and which engages in a bearing receptacle provided in the fixed jaw.
  • Such guidance of the abutment on the vice body only acts in the direction parallel to the axis of rotation, so that the abutment does not move in the direction of the axis of rotation, but can rotate about the axis of rotation despite its guidance in the vice body.
  • This guide also prevents the abutment from tilting under the action of the clamping force.
  • the vise body on the one hand and on the slide or on the abutment on the other hand paired, parallel to the guide plane of the slide plane guide surfaces are provided, which are formed continuously on the vise body in the direction of the screw spindle axis both for the slide and for the abutment.
  • the guide surfaces on the vice body are preferably formed by the side walls of guide grooves and on the slide or abutment by the side walls of guide strips engaging in the guide grooves.
  • the guide strips on the abutment have a free play in the guide grooves in the direction perpendicular to the screw spindle axis and to the axis of rotation of the abutment, which enables the limited rotation of the abutment.
  • a comparable free play in the guide grooves can also exist with regard to the guide strips of the slide, if for guiding the slide transverse to the screw spindle axis and to its axis of rotation of the spindle nut mounted on the slide, separate guide surfaces which are essentially perpendicular to the guide plane of the slide are provided.
  • the spindle nut has as its outer circumferential surface a rotational surface coaxial with its axis of rotation and is arranged in a bearing receptacle formed in the slide with a corresponding inner surface.
  • the spindle nut has the shape of a cylinder with a threaded bore running through the cylinder transverse to the cylinder axis.
  • the movable jaw on the slide can expediently be displaced in the direction of the screw spindle axis.
  • the machine vise has a vise body 1.
  • a fixed jaw 2 is attached to it, which carries an interchangeable top jaw 2 '.
  • the fixed jaw 2 is fastened to the vice body 1 by means of screws 3 and a fitting strip 5 which runs on the underside of the jaw 2 and extends transversely to the clamping direction indicated by the double arrow 4 and which engages in a fitting groove 6 correspondingly running in the vice body 1.
  • This screw spindle 8 is rotatable and axially immovable with respect to the vice body 1 in a spindle bearing, generally designated 9, and carries a spindle nut 10 which moves on the screw spindle during the spindle rotation.
  • the screw thread 11 on the screw spindle 10 extends only over the 1 indicated by the double arrow 12 in FIG. 1, so that the spindle nut 10 can also be adjusted only over this threaded area on the screw spindle 8.
  • the spindle bearing 9 is formed by two coaxial roller bearings 14 with the spindle axis 13, which are located on both sides of a bearing collar 15 provided on the screw spindle 8 and support the screw spindle 8 on their bearing collar 15 axially immovably against an abutment 16, which accommodates the bearing housing 14 17 forms, which is closed by a screwed into the abutment 16 ring cover 18.
  • the screw 8 is rotated optionally from one of its two ends, which are designed for fitting a key with suitable key surfaces 8 '.
  • the abutment 16 is arranged on the fixed jaw 2.
  • the spindle nut 10 is located on a slide 19 which carries the movable jaw 7 and which is displaceably guided on the vice body 1 parallel to a guide plane 20 which is indicated by the dashed lines in FIGS. 3 and 5 and runs through the axis 13 of the screw spindle 8.
  • the abutment 16 is mounted on the fixed jaw 2 and the spindle nut 10 on the slide 19 each rotatable about mutually parallel axes 21 and 22. These two axes are perpendicular both on the axis 13 of the screw spindle 8 and on the guide plane 20 of the slide 19.
  • the abutment 16 is also guided in the vice body 1 parallel to the guide plane 20 of the slide 19. It has a bearing journal 23 which is coaxial with its axis of rotation 21 and which engages in a cylindrical bearing receptacle 24 provided in the fixed jaw 2. Perpendicular to the axis of rotation 21 and to the axis 13 of the screw spindle 8, the abutment 16 has sufficient free play in its guidance on the vice body 1, indicated in FIG. 5 by the column 25, which the rotation of the abutment 16 about its axis of rotation 21 in for alignment sufficient extent on the spindle axis 8.
  • parallel guide surfaces 26, 27 are provided, which are continuous on the screw body 1 in the direction of the screw spindle axis 13 both for the slide 19 are also formed for the abutment 16.
  • These guide surfaces 26, 27 are formed on the vice body 1 by the side walls of guide grooves 28 and on the slide 19 or abutment 16 by the side walls of guide strips 29 and 30 engaging in the guide grooves 28.
  • the spindle nut 10 has the shape of a cylinder with the threaded section 12 of the screw spindle 8 running through the cylinder transverse to the cylinder axis 22 receiving threaded bore 10 '.
  • the spindle nut 10 is arranged in a bearing receptacle 39 in the slide 19 which is coaxial with it and also has a cylindrical inner surface.
  • the screw 8 itself runs in the slide 19 in a longitudinal bore 32, which has sufficient free play compared to the screw 8, so that the screw 8 in the longitudinal bore 32 is slightly pivotable about the axis of rotation 22 of the spindle nut 10.
  • the screw spindle 8 is sealed against the slide 19 by elastic sealing rings 33.
  • the axis of the longitudinal bore 32 runs through the intersection of the axis of rotation 22 and the thread axis of the spindle nut 10 which coincides with the screw spindle axis 13.
  • the movable jaw 7 can be displaced on the slide 19 in the direction of the screw spindle axis 13 in order to be able to roughly change the span between the two jaws 2, 7.
  • a correspondingly designed T-stone 35 is guided in a T-groove 34 of the slide 19 which is open towards the movable clamping jaw 7 and which is screwed to the movable jaw 7 by means of screws 36.
