Definitions

  • the invention relates to a vice with a basic body, a fixed clamping jaw attached to the basic body and a linearly adjustable guiding mechanism on the basic body, tensioning slide against the clamping jaw, with interchangeable jaw elements on the mutually facing sides of the clamping slide and fixed clamping jaw are arranged with in particular profiled clamping surfaces, between which a workpiece is held.
  • Such vices are generally known and are available in practice in most workshops in order to be able to clamp workpieces that are to be machined manually.
  • the cocking slide is arranged on a threaded spindle mounted in the base of the vice so that when the threaded spindle rotates, the cocking slide moves in the direction of the fixed clamping jaw or away from it by means of a hand crank, and thus between the clamping slide and clamping jaw positioned workpiece clamped between the clamping surfaces of the jaw elements or a clamped workpiece is released.
  • a clamped workpiece can be machined on the surfaces protruding upwards or laterally from the vise. To machine the other sides, it is necessary in each case to release the workpiece from the clamping, reposition it and clamp it again. This is often perceived as complex, in particular if the workpiece is to be processed, for example, with a column drill has to assume a defined position, since the positioning of the workpiece is then only possible using special spacers which are positioned between the workpiece and a support surface of the base body. This type of positioning is often not sufficiently precise and is also very time-consuming.
  • the object of the invention is accordingly to provide a vice of the type mentioned, which allows multi-sided machining of a workpiece with little positioning and clamping effort.
  • the jaw elements are arranged rotatably about a common axis running parallel to the adjustment direction of the clamping slide on the clamping slide and clamping jaw and are mounted such that a rotary movement of the jaw elements also under the effect of the clamped Workpiece on the jaw elements acting clamping forces is possible, and that at least one of the jaw elements can be determined in several rotational positions by a locking device.
  • the jaw element arranged on the clamping jaw is formed on an axial end of a pin, which is rotatably mounted in the clamping jaw by means of an axial bearing, in particular, which absorbs clamping forces, and the jaw element is preferably displaced from the clamping slide by 0. Holds 1 mm to 0.3 mm apart, the jaw element provided on the clamping slide can be mounted in the same way. This enables the jaw elements to be rotated in a simple manner under the action of an axial load.
  • the free axial end of the pin facing away from the jaw element is expediently guided out of the jaw and provided with an actuating element for rotating the pin and engages with a locking device for locking the pin bringable.
  • a flange is advantageously formed on the free end of the pin protruding from the clamping jaw, which flange has a flat toothing on its surface facing away from the clamping jaw, and is a locking block on the base body with one of the
  • the spur gear associated with the spur gear is held in a rotationally fixed manner and guided against the flange and movable back in order to bring the two spur gears into engagement with one another to fix the pin and to detach them again.
  • a scale is preferably provided on the outer circumference of the flange for reading the respective rotational position of the jaw element mounted on the clamping jaw and thus of a clamped workpiece.
  • the jaw elements can be advantageous to provide the jaw elements with a support web on their lower area facing the base body, on which a workpiece to be machined can be positioned at a distance from the base body for clamping, so that additional positioning aids are not required.
  • the upper side of the base body as a support surface, on which spacer elements can be placed for positioning a workpiece, which elements can be removed before the workpiece is rotated, in order to create the space below the workpiece which is necessary for the rotation.
  • the positioning and clamping process can also be kept low by the clamping surfaces of the jaw elements being complementary to the outer contour of a workpiece to be clamped.
  • the clamping surfaces of the jaw elements can each be formed as recesses in the form of cylindrical sections.

  • the threaded spindle 19 has an outer thread 20 on its outer circumference, onto which a tensioning slide 2 is screwed.
  • the cocking slide 2 protrudes upward out of the base body 1 and, as is shown in particular in FIG. 3, lies on the top of the base body 1 and is guided on the base body 1 so as to be adjustable in the axial direction of the threaded spindle 19 and secured against rotation.
  • a fixed clamping jaw 3 is further provided on the base body 1, which is screwed onto the top of the base body 1.

Abstract

L'invention concerne un étau comportant une structure de base (1), une mâchoire fixe (4) fixée à ladite structure de base, et un coulisseau (2) assurant le serrage contre la mâchoire et guidé mobile en ligne droite sur la structure de base. Des éléments de mâchoire remplaçables (4, 5), entre lesquels est maintenue une pièce, sont disposés sur les côtés opposés du coulisseau et de la mâchoire fixe. Ces éléments de mâchoire sont par conséquent disposés sur le coulisseau et la mâchoire de manière à tourner autour d'un axe commun (X) parallèle au sens de déplacement du coulisseau, et sont montés de manière à permettre un mouvement rotatif des éléments de mâchoire même sous l'action des forces de serrage s'applicant sur ces éléments lors du serrage de la pièce, et au moins un des éléments de mâchoire peut être fixé dans une pluralité de positions de rotation par un dispositif de blocage (10-13).
