Definitions

  • the invention relates to a vice, comprising a fixed buttock and a toe, which is rotatably supported by a threaded spindle, one of which, having a pivot end in the front jaw along a guide relative to the buttock, wherein the threaded spindle has an external thread, the corresponds with an arranged on the buttock internal thread.
  • Such vices are well known.
  • a rotational movement of the swivel causes a longitudinal movement of the screw and the movable toe to clamp or release a workpiece between the jaws.
  • a disadvantage of such vises is that it is very time-consuming to move the movable toe for clamping a workpiece, since the movable toe is only moved by a pitch of the screw at each revolution of the swing.
  • the invention aims to remedy this situation.
  • the invention is based on the object to provide a vise, which allows a free displacement of the toe when required unrestricted function of the vise as needed.
  • this object is achieved in that the internal thread is placed in a arranged in the rear jaw adjusting nut and is designed as a partial thread with a semicircular cross-section, which merges into a recess, wherein the recess is formed such that the spindle by moving the adjusting nut orthogonal to the spindle axis with the partial thread in or out of engagement.
  • a vise is created, which allows a free displacement of the toe when required unrestricted function of the vise, as needed.
  • a rapid adjustment of the distance between the front and rear jaw on the dimension of the workpiece to be clamped allows.
  • the adjusting nut is connected to at least one spring element, via which the adjusting nut is pressed with the partial thread against the threaded spindle.
  • the at least one spring element is a leaf spring which extends substantially parallel to the spindle axis.
  • the at least one spring element is a helical spring, which bears against the inner wall of the buttock. hereby is an orthogonal directed to the threaded spindle return of the adjusting causes.
  • exactly two screws are resiliently arranged, which rest parallel to each other on the adjusting nut. As a result, tilting of the adjusting nut is prevented.
  • the adjusting nut is designed in the form of a bolt, which is movable in a cylindrical recess of the buttock.
  • a cylindrical diameter-reduced shoulder is advantageously integrally formed on the adjusting nut, whereby a contact surface for the at least one spring element is formed.
  • the threaded spindle has a self-locking trapezoidal thread. As a result, a high and optimally distributed clamping force for rapid opening and closing of the vise is effected.
  • the threaded spindle is biased in the toe piece via a spring.
  • the chosen as an exemplary vise consists essentially of a fixed buttock 1 and a toe 2, which is connected via a spindle 3, which is provided at its end with a pivot 4, and a guide rail 5 relative to the buttock 1 slidably connected thereto.
  • the threaded spindle 3 passes through an adjusting nut 6 and opens into a housing tube 7. Furthermore, the main body 101 is penetrated by the formed on the toe 2 guide rail 5, which is slidably mounted in the body 101
  • the buttock 1 is produced as a drop forging part and consists essentially of a base body 101, on which an attachment jaw 9 is formed. Below the attachment jaw 9, a curvature 102 is introduced in the embodiment. The buckle 102 is used together with the front jaw 2 opposite provided buckle 22 of the clamping of tubular workpieces.
  • a tunnel-like indentation 103 is arranged in the longitudinal direction, through which the spindle 3 is guided.
  • two mutually remote feet 104 are arranged on the base 101 opposite, which are formed in the manner of a C-profile.
  • the feet 104 each have mutually directed protrusions 1040, which each engage in an introduced in the guide rail 5 groove 51, so that the guide rail 5 is guided in the protrusions 1040 of the feet 104.
  • a screw 105 In the center is guided by the bulges 1040 of the feet 104, a screw 105.
  • the screw 105 penetrates an inserted into the guide rail 5 within the groove 51 slot 52.
  • two holes 106, 107 are introduced into the base body 1 on both sides of the indentation 103, in which an adjusting nut 6 is slidably mounted.
  • the bore 107 in this case has a smaller diameter than the oppositely disposed bore 107.
  • the diameter of the bore 107 corresponds approximately to the diameter of the shoulder 6; the diameter of the bore 106 corresponds approximately to the diameter of the main body 61 of the adjusting nut. 6
  • the drop forged front jaw 2 is essentially formed from a base body 21, to which a front jaw 10 is formed. Below the front jaw 10, a bulge 22 is introduced for clamping tubular workpieces in the embodiment.
  • a bore 23 for carrying the spindle 3 is introduced in the main body 21 of the toe 2.
  • a guide rail 5 is integrally formed on the base body 21, which is mounted displaceably in the base body 101 of the buttock.
  • the spindle 3 has at its one end a spindle head 31, which is provided for receiving the swivel 4 with a through hole 32. At its end opposite the spindle head 31, a double-barreled trapezoidal thread 33 is introduced into the spindle 3. Between the trapezoidal thread 33 and the spindle head 31 is in the spindle 3 a - not shown - circumferential groove for Recording a - not shown - designed snap ring.
  • the spindle 3 is guided through the bore 23 of the toe piece 2 in such a way that the spindle head 31 abuts the bore 23 in a protruding manner on the base body 21 of the toe piece 2.
  • the adjusting nut 6 is essentially formed by a cylindrical base body 61, on which on one side in the middle a likewise cylindrical shoulder 62 with a smaller diameter is integrally formed, whereby an annular stop 63 is formed on the base body 61. On the stop 63 diametrically two cylindrical receptacles 64 for a coil spring 13 are arranged. In the main body 61, a recess 65 is introduced, which is formed in the manner of a slot. On its side facing the shoulder 62, a partial thread 651 is inserted in the equipment 65. The partial thread 651 is - corresponding to the thread 33 of the threaded spindle 3 - provided with a double-barreled trapezoidal thread. The recess 65 is formed such that the spindle 3, which protrudes through the recess 65, by moving the adjusting nut 6 is orthogonal to the spindle 3 with the partial thread 651 in or out of engagement.
  • the adjusting nut 6 is introduced into the bore 106 of the base body 101 buttock 1, that the base body 61 rests in the bore 106, wherein the shoulder 62 protrudes through the bore 107, the spindle 3 is guided through the recess 65.
  • a coil spring 13 is in each case arranged, which is biased against the inner wall of the main body 101 of the buttocks 1. Due to the bias of the coil springs 13, the trapezoidal thread 33 of the spindle 3 with the partial thread 651 of the adjusting nut 6 is engaged.
  • the adjusting nut 6 is formed in the form of a cylinder, which is provided in the aforementioned manner with a slot-shaped recess 65 which has a partial thread 651. Close to the recess 65, a slot-like recess 66 for receiving a leaf spring 14 is inserted in the base body 61 of the adjusting nut 6.
  • the adjusting nut 6 designed in this way is introduced in the base body 101 of the buttock in such a way that it bears in the bore 106, 107 arranged opposite to one another, the spindle 3 protruding through the recess 65.
  • the holes 106, 107 both have an identical diameter in this embodiment, which substantially corresponds to the outer diameter of the main body 61 of the adjusting nut 6.
  • the leaf spring 4 is angled at its end opposite the adjusting nut 6. In the assembled state, the leaf spring 14 is guided along the indentation 103 of the main body 101, wherein the angled end of the leaf spring 14 comprises the base body 1. This angled end of the leaf spring 14 is screwed by a screw 141 with the main body 101 (see. FIG. 7 ).
  • a limiting pin is provided to ensure a defined positioning of the adjusting nut 6, in two wells at corresponding positions "spindle thread 33 with partial thread 651 engaged” and "spindle thread 33 with partial thread 651 disengaged” Adjustment nut 6 are inserted outside in this, can be latched.
  • the limiting pin is guided by the main body 101 of the buttock 1 and mounted so resiliently that it is biased against the trough of the adjusting nut 6.
  • the limiting pin By operating an operating device provided on the main body 101, the limiting pin can be moved out of the trough by actuation of a lever, whereby a displacement of the adjusting nut 6 is made possible until the limiting pin engages in the second trough of the adjusting nut 6.
