Definitions

  • the spindle is equipped with the cross pin, and the spindle nut is supported on the movable jaw in the clamping direction.
  • the spindle advanced after loosening the spindle nut must be pulled back and the spindle nut tightened with the spindle held in the retracted position.
  • the spindle nut must be loosened and the spindle pushed forward.
  • the object is achieved to create a vise that can be produced while maintaining the advantageous properties of the vices of the type mentioned without any significant additional effort, but is easier and faster to operate.
  • it is sufficient to tighten a workpiece to tighten the spindle (or the spindle nut) and to loosen the workpiece to loosen the spindle (or spindle nut) without the spindle also having to be moved and held in the displaced position.
  • the pair of elements cannot exert any force pushing back the movable jaw when the spindle is released, because the groove flank facing the fixed jaw runs approximately in the direction of the spindle and the spindle nut or the spindle head on the movable jaw is only supported for tightening, but can stand out from her or his support surface (in the vice of DE-PS 26 52 946, the spindle head is lifted off its support surface by the spring when the spindle is released).
  • the embodiment according to claim 6 corresponds to the first of these two alternative possibilities.
  • 1 denotes the bed (base body), 2 the fixed jaw, 3 the movable jaw, namely the jaw which can be displaced along the bed 1 in a parallel guide (not shown), 4 a workpiece clamped between the jaws 2 and 3, 5 the inclined spindle with the spindle head 6, and 7 the spindle nut.
  • the pair of elements consisting of the spindle 5 and the spindle nut 7 is at the top in a cavity 8 of the displaceable Jaw 3 and down in a longitudinal slot 9 of the bed 1 in the longitudinal direction pivotally and axially immovable.
  • a spherical surface of the spindle head 6 is supported on a curved surface 10 and a ring 13 held opposite the head 6 on the spindle 5 by a snap ring 12 on the spindle 5 on a surface 14 coaxial with the surface 10, and the spindle is between the head 6 and the ring 13 arranged in an elongated hole 15.
  • the spindle nut 7, like a part 16 of the displaceable jaw 3, is guided in the longitudinal slot 9 of the bed.
  • the lower end of the spindle nut 7 is provided with a cylindrical cross pin 17 which projects beyond the spindle nut 7 on both sides.
  • the spindle nut 7 is loaded by a leaf spring 18, which strives to pivot the spindle 5 together with the spindle nut 7 towards the fixed jaw 2.
  • the bed 1 has on both sides of the longitudinal slot 9 a series of cross-sectionally rectangular transverse grooves open at the bottom, for example 20, 21, 22, which lie opposite one another in pairs in order to receive the transverse pin 17.
  • the depth of the grooves 20, 21, 22 is greater than the radius of the cross section of the pin.
  • the cross-section of the groove can also be rounded at the top, that is to say it can be U-shaped in reverse.
  • the spindle nut 7 When the spindle 5 is in any position of the displaceable jaw 3, in which the pin 17 is either wholly or partly in one of the grooves or is pressed between two grooves by the spring 18 against the surface 23 in which the grooves are formed is solved, the spindle nut 7 is subjected to the feed caused by the spindle 5 and the spring force of the spring 18. The spindle nut 7 goes down and swivels (around the spindle head 6) to the right in the drawing. One pushes through a nose 24 on the spindle nut ter 7 formed shoulder to a formed in the cavity 8 of the movable jaw 3 corner 25 when the pin 17 is a small distance from the surface 23. In this state, which is shown in Fig. 3, the pin 17 can not engage in one of the grooves, the jaw 3 is freely displaceable.
  • the pin 17 When the jaw 3 is advanced until it abuts the workpiece 4, the pin 17 is generally not in front of one of the grooves, but e.g. As in Fig. 3, in front of the surface 23 between the grooves 21 and 22.
  • the pin 17 When tightening the spindle 5, the pin 17 first touches the surface 23, it is pressed by the spring 18 against this surface and slides on it until it at further tightening of the spindle 5 is pressed by the spring 18 into the groove 21 and, when the spindle 5 is further tightened, it is pressed against the left flank of this groove 21 in the drawing, as shown in FIG. 4.
  • the displaceable jaw 3 is pressed against the workpiece 4, which is supported opposite this jaw 3 on the fixed jaw 2 (FIG. 1).
  • the pin 17 When the spindle 5 is released, the pin 17 first detaches from the left flank of the groove 21 because the distance between the pin 17 and the spindle head 6 increases and the spring 18 acts. Under this effect, the pin 17 then abuts the right flank of the groove 21, and when the spindle 5 is loosened further, the pin 17 slides downwards on this groove flank, the horizontal component of its obliquely downward movement causing the displaceable jaw 3 is pushed back, as shown in Figures 5 and 6. In addition to the vertical course of the groove flank, a prerequisite for this is that the spring 18 holds the pin 17 on the right flank of the groove 21.
  • the pin 17 leaves the groove 21 and slides to the right on the surface 23 until the shoulder of the spindle nut 7 formed by the nose 24 abuts the corner 24.
  • the movable parts of the displaceable jaw 3 thus again reach the position shown in FIG. 3, the jaw 3 is freely displaceable.
  • the ratio of the spindle rotation to the horizontal component determines the path of the pin 17 by the pitch of the spindle thread and the inclination of the spindle 5 and is relatively very large. It can therefore be exerted without considerable effort to release the jaw 3 and this jaw 3 can be easily released even if it has stuck in its (not shown) parallel guide with high clamping force.
