Definitions

  • the invention relates to a device for supporting objects ; which device is versatile and can be used, for example, as a support winch in steel, machine and device construction, in measuring laboratories on drilling, milling, CNC and transfer machines.
  • the device consists of a base with a length-adjustable spindle which is provided on the head side with an opening for receiving insert pieces.
  • the object of the invention is to provide a measure which prevents the spindle from being inadvertently unscrewed completely from the base.
  • the invention proposes that a catch is provided which engages in the outer position of the spindle under the action of a spring.
  • a locking device is preferably provided which can clamp the spindle in any desired position.
  • FIG. 1 shows a diagrammatic illustration of the device
  • FIG. 2 shows the device from below with the base cut open
  • FIG. 3 shows an axial longitudinal section of the catch
  • FIGS. 4 to 7 show various embodiments of the attachments in a diagrammatic illustration.
  • the device according to the invention has a base 1, which can have a magnet insert 2 on the base side, by means of which the device can be fastened on a metallic base without clamping devices in any position, for example in a vertical or horizontal position, thereby eliminating time-consuming tensioning.
  • the upper end of the device designed as a screw stand in the present exemplary embodiment has a nut thread 3 into which a spindle 4 is screwed, which has a rimmed head 5 which is provided with holes 6 for inserting positioning pins and also a central opening 7 for one Insert bolt 8 has, on which attachments 9 can be attached.
  • a pointed attachment is provided, which may be the same as a ball attachment according to FIG. 4, a prism attachment according to FIG.
  • an articulated attachment according to FIG. 6 a centering attachment according to FIG. 7. is interchangeable.
  • the attachments and the end of the insert bolt 8 can be designed such that the connection between the insert bolt and the attachment is formed as a joint which enables the attachment to be pivoted sideways relative to the bolt.
  • an automatic locking mechanism which has a bolt 11 loaded by a spring 10, which in the uppermost position of the spindle into a bore 12 of them snap into place.
  • the bolt 11 is guided in a sleeve 13, which is screwed with an end thread 14 into a nut thread 15 of the base 1.
  • the spring 10 is supported at one end on the bottom 16 of the sleeve 13 and at the other end on a shoulder 17 of the bolt 11.
  • the bolt 11 is provided with a stepped pin 18 which loosely penetrates a bore 19 in the base 16 and is fastened in the base 20 of a capped cap 21 which is guided on the sleeve 13 so as to be longitudinally displaceable.
  • a locking screw 22 is provided, which in the present case corresponds to the end position is diametrically opposite and is 1 lng screwed in a nut thread 23 of the base. By tightening the locking screw 22, the spindle 4 is prevented from rotating in the base 1.
  • the device according to the invention can be used as a support winch when clamping workpieces in the manner of a vice and ensures precise support of the tools even under high pressure in any e.g. vertical and horizontal position.
