Definitions

  • Jaw vices and similar clamping devices are generally provided with a supporting frame adapted to,be secured to a vice bench or a machine table.
  • Said supporting frame has a fixed clamping member projecting upwardly therefrom, and said clamping member is provided with a jaw plate.
  • the supporting frame is also provided with guides, and these guides have guiding surfaces for a movable clamping member which is also provided with a suitable jaw plate.
  • the movable clamping member is adapted to be moved against the fixed clamping member by means of a screw or some other actuating device so that the jaw plate of the movable clamping member can be pressed against the jaw plate of the xed clamping member or against an object which is clamped between said jaw plates.
  • a clamping device of that kind When a clamping device of that kind is tightened, the clamping members will be subjected to a torque which causes a lifting of the movable clamping member which is permitted by the inevitable clearance in the guiding paths of said movable clamping member. This lifting leads to a number of disadvantages of which the following may be mentioned:
  • the power transmission to the movable clamping member is adapted to be made via inclined sliding surfaces whichrare arranged to provide a clamping action at the same time as they bring about a downward pull of the movable clamping member.
  • the power transmission to the movable clamping member is adapted to be made over link rods, said link rods being pivoted to the movable clamping member and adapted to press said clamping member against the xed clamping member. Said link rods are inclined so that they also impart a downward pull to the movable clamping member.
  • the present invention relates to a jaw vice in which the 3,232,592 Patented Feb. l, 1966 bending of the supporting frame at high clamping pressure is compensated through a corresponding inclination of said movable clamping member, whereby an accurate parallelism between the clamping surfaces of the clamping members will be obtained and the exact position of the clamped object will be maintained.
  • a jaw vice has a fixed clamping member and a supporting frame, said supporting frame having a first set of guiding surfaces with which guiding surfaces provided on the movable clamping member cooperate, said movable clamping member being displaceable towards and from said xed clamping member by means of an actuating member, for example a screw, with an auxiliary sliding member being connected between said actuating member and said movable clamping member, said auxiliary member having guiding surfaces which cooperate with a second set of guiding surfaces on said supporting frame, said lirst set and said second set of guiding surfaces being provided at opposite sides of said supporting frame.
  • the auxiliary sliding member is connected to said movable clamping member by means of a number of connecting members with the connection between at least one end of said connection members and the part connected thereto being linked or bendable to a certain degree.
  • the invention is substantially characterized by the fact that the point of connection between said connection members and. said auxiliary sliding member lies in a plane perpendicular to the direction of movement of said auxiliary sliding member and said movable clamping member, said plane being located nearer to said fixed clamping member than a plane which is parallel to the rst mentioned plane and going through the clamping surface of said movable clamping member.
  • FIG. l illustrates a jaw vice of a conventional kind in which the bending of the supporting frame has been shown in an exaggerated way
  • FIG. 2 is a longitudinal section through a jaw vice according to one embodiment of the present invention along the lines II-II and IIa-Ila, respectively, in FIG. 3,
  • FIG. 3 is a cross section of the same jaw vice along the line III-III in FIG. 2,
  • FiGS. 4 and 5 illustrate cross sections through different parts of the jaw vice, where carrier members for the movable clamping member are provided, and
  • FIGS. 6 and 7 are sections on a greater scale through the jaw plate of the fixed clamping member of two different embodiments of the jaw vice.
  • 1 designates a supporting frame for a jaw vice, said supporting frame having two guides 2 and 3.
  • the guides 2 and 3 are connected together at both ends of the jaw vice by means of yokes 4 and 5 which may be secured to the guides by means of moulded connections or by screw connections or by any other suitable means.
  • an actuating member in the form of a screw 6 is located, said screw 6 being rotatably mounted in the yokes 4 and S but prevented from being displaced in its longitudinal direction.
  • a fixed clamping member 4a which is provided with an inclined sunface 4c for receiving a jaw plate 4b.
  • the clamping member 4a is rigidly secured to the guides and preferably integral therewith.
  • the jaw plate 4b has an inclined surface 4d which lies against the inclined surface 4c of the xed clamping member 4a.
  • the .jaw .plate 4b is fastened to the clamping member 4a by means of screws de and elastic washers 4f and is adapted to make a limited movement relative to the clamping member 4a.
  • the screw 6 cooperates with a nut '7a which belongs to an auxiliary sliding member 7 (FIG. 2) or which cooperates with such member.
  • the nut 7a may be a separate unit in the auxiliary sliding member 7, and may be kept in the auxiliary sliding member in such a Vway, that it is locked for movement in the direction of movement of said auxiliary sliding member but allowed to be slightly displaced in a direction perpendicular to 4movement of said auxiliary sliding member.
  • the auxiliary sliding member 7 is displaceably mounted between the guides 2 and 3 and has guiding surfaces S which cooperate with corresponding guiding surfaces 9 of .said guides 2 and 3.
  • a movable clam-ping member 1G is provided with a surface 19a from which a number (preferably four) of carrier members 11b, 12b, 11011, 1206 project.
  • the carrier members are provided with guiding surfaces 11, 12, 110, 126 which cooperate with the upper guiding surfaces 13 and 14 of the guides 2 and 3.
  • the carrier members there are two front carrier members 11%, 12015 and two rear carrier members 11b, 12b.
  • the carrie-rs members 11b, 12b, 1105, 121119 are located in holes 11a, 12a, 1190.', 120e in the movable clamping member 1?.
  • the upper surfaces of the rear carrier members 11b, 12b are domeshaped in order to allow a slight tilting movement of the movable clamping member on said surface.
  • the front o part of the movable clamping member rests on the resilient carrier members lltlb, 12d-b, and the rear part rests on the dome-shaped carrier members 11b, 12b. Between the lower surface of the movable clamping member and the guides 2 and 3 there is a clearance.
  • each of said link rods 15 and 16 has a fulcrum pin or a threaded nut 17 and 18, respectively, at the lower end of said link rod, said fulcrum pin or nut being pivoted in recesses 19 and 20, respectively, which are provided in the sides of the auxiliary sliding member 7 at the front part thereof.
  • the fulcr-um pins or nuts 17 and 18 may be adjustable on the link rods 15 and 16.
  • the link rods may, for example, be threaded in said fulcrum pins or nuts or, still better, the link rods may run freely through said fulcr'um pins or nuts and be provided with separate nuts 17a, 18a at their ends.
  • a rod 23 common to the link rods 15 and 16 is provided in the movable clamping member 10, said rod 23 going through the upper ends of said link rods.
  • link rods 1S and 16 may be used. lnstead of the dome-shaped nuts 17 and 1S, said nuts may have cylindrical surfaces which coopera-te with correspending pivoting recesses in the auxil-iary sliding member 7.
  • the link rods may be provided at their upper ends with separate axle spindles or with dome-shaped pivoting means, which cooperate with corresponding recesses in the movable clamping mem-ber.
  • the link rods may also .be replaced by strong disc springs or the like, or by screws, or other connecting members, which .may be rigidly secured to said auxiliary sliding member and/or to said movable clamping member but slightly bend-able or tiltable relative to at least one of said members.
  • said front and said rear carrier members may be resilient or elastical to such an extent that the parallelism between the clamping surfaces of the fixed and the movable clamping members will be obtained or maintained during the clamping process.
  • the rear part of the movable clamping member 1t) is secured to said auixliary sliding member 7 by means of screws 24 and 25. Said screws are threaded in the movable clamping member and run freely through holes in said auxiliary sliding member 7. As is clearly illustrated at 26 and 27 in FIG. 2, there must be a sufficient clearance round the screws 24 and 25 where they extend through the auxiliary sliding member. 4Under the heads of the screws 24 and 2.5 there are elastic washers 28 and 29; said washers being adapted to elastically press the guiding surfaces 8 of said auxiliary sliding member 7 against the gui-ding surfaces 9 of said guides 2 and 3, and at the same time press the movable clamping member 10 with its carrier members and their guiding surfaces against the guiding surfaces 12 and 13 of the guides 2 and 3.
  • Two helical springs 30 and 31 which are inserted in holes 32 and 33, respectively, in said auxiliary sliding member 7, tend to press said sliding member forwards against the screws 24 and 25.
  • the springs 3) and 31 may preferably act with such a strength that the guiding surfaces 8 of the auxiliary sliding member 7, under the action of the link rods 15 and 16, will be pressed against the guiding surfaces 9 of the guides 2 and 3 also at the front part of said auxiliary sliding member.
  • the arrangement of the spring 30, the screws 25, the auxiliary sliding member 7, the link rods 15, 16 and the movable clamping member 1) forces the guiding surfaces of the movable clamping member to be pressed tightly against the guiding surfaces of the guides 2 and 3 during the clamping process and also before the clamping process is started. This will be the case, also when said guiding surfaces are worn after long use.
  • connection between the link rods or other connection members, such as screws, disc springs or the like, and the auxiliary sliding member 7, is located in front of the clamping surface of the movable clamping member 1t), it will be possible to match the force which is required to pull down the movable clamping member 1@ to the lifting force which has been described in the foregoing.
  • the angle of inclination of the link rods which means the enclosed angle between the link rods and the supporting frame, may be less than 60, and also less than 45. It may preferably be not greater than 37, so that the losses of the clamping force due to the pulling down of the movable clamping member 10 will not decrease the clamping pressure between the clamping surfaces to any appreciable extent.
  • the guiding surfaces 11, 12, 110, of the carrier members 11b, 12b, 110k, 12% as well as the guiding surfaces 6 of the auxiliary sliding member 7 are made of a material with a low friction coefficient. Therefore, no self-blocking of the movable clamping member will occur during the clamping process and, therefore, about the same clamping force will be obtained as in a conventional jaw vice, which is not provided with any means for pulling down the jaw plates durinf7 the clamping process.
  • This arrangement leads to the effect, that the inclined jaw plate 4c will not press down the clamped object with too strong a force. There will be no sliding of the jaw plate 4c against the clamped object and, therefore, the position of the clamped object relative to the jaw plate will be maintained during the clamping process.
  • the elastic washers lltlc and 12de will be compressed during the clamping process and, therefore, the movable clamping member will occupy a slightly inclined position. This results in the desired compensation for the lack of parallelism being obtained. It is important that the elastic force of the elastic washers has just that magntiude, that for all possible clamping forces, and for all possible distances between the clamping surfaces, the parallelism between the clamping surfaces of the clamping members 4a and 10 is maintained.
  • the bending of the supporting frame increases also with increasing clamping distances.
  • the pivots of the link rods in the auxiliary sliding member are positioned in a vertical plane which is displaced in a direction towards the fixed clamping member, from that vertical plane, which passes through the clamping surface of the movable clamping member.
  • the bending of the supporting frame causes the auxiliary member 7 to be moved to a lower position, while the movable clamping member is lifted to a more elevated position.
  • the angle between the link rods to the direction of movement of the movable clamping member will be greater if the pivot of the link rods in the auxiliary sliding member are displaced in the direction from the fixed clamping member towards the movable clamping member. It is also apparent, that if the distance between said pivots and the movable clamping member is considerable, said angle will alter with the bending of the supporting frame. A greater angle means, however, a more powerful pulling down of the front end of the movable clamping member. Thus, it is possible to obtain a substantially complete compensation of any lack of parallelism between the clamping surfaces which may be caused by the bending of the supporting frame.
  • the carrier members in the movable clamping member enable the link rods to compensate the effect of the bending of the supporting frame because said bending leads to a greater down-pulling angle which, in turn, leads to a more powerful down-pull of the movable clamping member.
  • the carrier members are located in the front and rear ends of the movable clamping member at a rather great distance from each other, the bending of the supporting frame will bring about only a slight lifting of the movable clamping member, which lifting can be compensated as has been described in the foregoing.
  • the fixed clamping member 4a may have a jaw plate 4b, the rear surface la? of which is inclined and cooperating with a corresponding inclined surface 4c of the fixed clamping member.
  • the jaw plate 4b may be secured to the clamping member 4a by means of screws 4e which are going through the jaw plate in holes with some clearance, so that the jaw plate is slightly slidable on the clamping Imember.
  • Elastic washers 4f may be placed under the heads of the screws fie for keeping the jaw plate pressed against the clamping member.
  • the inclined surfaces 4c, 4d serve the purpose of pressing the jaw plate downward against the supporting frame li. ln FIGS. 6 and 7 it is illustrated on an exaggerated scale, that the bending of the supporting frame brings about a slight inclination of the fixed clamping member da.
  • the jaw plate 4c rests against the supporting frame 1 in a point lying at a distance x from the inclined surface of the fixed clamping member. Consequently, the surface 4d of the plate will slide a little against the surface 4d of the clamping member during the clamping process. Because of that, the lifting of the jaw plate 4d and the clamping surface 4g will be less than if the jaw plate had been rigidly secured to the surface 4c of the clamping member 4a.
  • the point of support y is rather close to the surface 4c of the clamping member 4a.
  • the lifting of the clamping surface 4g which occurs because of the swinging 'movement of the lever z will, therefore, be greater than in the arrangement according to FIG. 7 where the distance x1 between the supporting point y1 and the surface 4c is greater than in FIG. 6, and in which the length of the lever z is Zero.
  • the supportting point y1 is more elevated than in the arrangement according to FEiG. 6, where the supporting point is y.
  • the difference between y and y1 is designated Ay and is dependent upon the bending of the supporting frame.
  • This optimal value of x can only be determined in an experimental way, and it is an object of the present invention to arrange the point of abutment y in such a wa, that is, at such a distance x from the surface 4c, that the lifting of the clamping surface 4g relative to a lixed reference surface level will be minimum.
  • the reference level can be equal to the upper surface level of a jaw bench or machine table on which the jaw vice is mounted.
  • the jaw plate 4b can also be provided with a slot ik in the rear part thereof as is illustrated in FG. 2.
  • abutment y as illustrated, is located beneath the slot 4h, the jaw plate 4b may be able to make a downward movement during the clamping process, so that the described lifting of the jaw plate can be completely conipensated.
  • the spring action of the part 4e which is located between the abutment point y and the slot 4h, serves as a force of restoration for the said downward movement.
  • the jaw plates may be unsymmetrically pulled down when the clamped object is located unsyrnmetri'cally between said jaw plates. This leads to a less accurate clamping of the object and it may also cause damage of the 'clamped object. Because the clamping member 4a during the clamping process will be slightly inclined, there will also by this reason, be a slight lack of parallelism between the clamping surfaces of the clamping members 4a and and 19, provided that said clamping surfaces were exactly parallel before the clamping process was started.
  • yone of said clamping surfaces (preferably the clamping surface of the fixed clam ing member) may be slightly inclined from the beginning so that parallelism will be exactly restored by the clamping pressure when the clamping process is completed.
