Definitions

  • the present invention relates to.-aworkpiece fixing device which chiefiyiserves to allow workpieces, which have to he tooled in-a horizontal or inclined position, to be quickly-fixed and'unfixed, or-changed imposition.
  • the manufacture of articles inseries very often-requires touchingupby hand which canbe done in -less time than is required for fixing unfixing or-changingthe position of the workpiece.
  • the opening and closingof known fixing devices requireswa-manm ual operation which compels-the workmam to lay down his tool inorder to be abletohold-the workpiece with onehand "and-to open-or close the fixing device with the other; and this-means a comparatively great'loss of time.
  • Fig. 2 the same-seenirom above.
  • Fig.3 the same, seen-from the front; with the bolt-head and bench top removed;
  • Fig. 4 a tongs-shaped fixing device, with two springs and ball-joint for setting the tongs in an oblique position, in side view, partly in section,
  • Fig. 5 the tongs-shaped fixing device according to Fig. 4 in end view, partly on the line 5-5.
  • Fig. 6 a spring guide bush for Figs. 4 and 5, seen from above,
  • Fig. 7 a gripper-shaped fixing device.
  • a base I (Fig. 1), which can be fixed to a workbench by screws 2, the bent-over part 3 of a tongs-arm 3 is firmly clamped by a nut 4 and a spring washer in such a way that it can be turned round, but yet remains sufliciently firm to tool the workpiece fixed in the device.
  • the tongs-arm 3 forms the lower part of the tongs and is provided with a swivelling clamping jaw gether.
  • the tongs-arm 3 which is fixed by a bolt 6 to the tongs-arm 3.
  • a spring 6 presses the clamping jaw 5 into its middle position.
  • the tongs-arm 3 ' has anslot FL-through whicha movable tongs-arm 8 passes which is connectedv to thetongs-arm 3 bya bolt
  • the tongs-arm 8 is: provided at one endwith a. clamping jawv l0. and at theother end with a handlev I I. Thetongs-arm. 8. is pressed upwards bya spring 12 acting through. apressure-key l3, whereby the jaws of the.
  • tongs are .pressedto- By pressing: on thehandle H in the direction of the arrow, which can be done by the workman with his .hand or arm without havingto-lay down his tool, the tongs opens.
  • the clamping jaws of the tongs are arranged in Fig. 1 at-an-acute angle-a to-the vertical plane; they mam-however; stand also horizontally or at another-angle. according to the kind of workpiece which is to be held in the device.
  • the side faces of the base I are parallel, so that the fixingdevice can be gripped in avice ltyas shown in Fig. 3,
  • Fig. 4 shows a tongs-shaped fixing device whichyin contrast to the fixing device of Fig. 1, can be set in any'desired position.
  • a tongs-arm lt and also a tongs-arm ll can beoperated the same manner as the tongs-arm 3 and 8 ct Fig, 1.
  • Aspring i8 is supported below on a ring l 9;;which is pressed by a ballnut ,Zilagainst a' shoulder on 'the. bent overen'd oi the tongs-arm 15 and presses above against a pressureekey 2i which presses the tongs-arm l1 upwards.
  • the opening of the tongs can, as in Fig. 1, be efiected by pressing the tongs-arm ll down.
  • the tongs-arm may also be connected by a pull member 33 to a pedal actuated by foot.
  • Fig. 7 shows a gripper-shaped fixing device.
  • An upper gripper part 3'! is connected to a downwardly directed arm 38 which can be fixed in a base as in Fig. 1 or in a base with ball-joint as in Figs. 4 and 5.
  • the connection of the gripper part 31 to the arm 38 may be direct or through a link.
  • the lower gripper part 39 may be connected to a pedal.
  • a two-armed lever 4-0 is provided, by means of which the gripper may be opened.
  • the lever 40 can be moved by the hand or arm of the workman, without his having to lay down his tool.
