Definitions

  • the invention relates to a screwing device for rods, in particular for screwing threaded rods into boreholes, in which there is an ampoule with a curable adhesive, with a housing having an axis AA with a drive end and with an interior space in the direction of the drive end opposite end of the housing has an opening for the insertion of the rod and in the distributed on the circumference of the axis and rotatably and radially movably mounted in a cage connect several rolling elements forming a locking mechanism, which are supported on the one hand on ramp surfaces on the inside of the housing are arranged, and on the other hand can be pressed against the rod by rotating the housing by means of the ramp surfaces with self-locking.
  • the known devices therefore generally have a continuous bore in the housing, so that the devices can be pushed onto a stud bolt so far that a section of the stud bolt which is not provided with threads can be reached by means of the rolling elements.
  • the length of the rolling elements also takes up only a fraction of the total length of the housing bore, and furthermore the maximum total length of the clamping bodies corresponds approximately to the diameter of the stud bolt to be moved.
  • the invention is therefore based on the object of specifying a screwing device of the type described above, with which rods of all types, including threaded rods, can be screwed into corresponding bores and / or threads quickly and reliably without special machining operations on the rods.
  • rods of all types including threaded rods
  • these screwing-in devices it should be possible with these screwing-in devices to produce threaded rods by cutting so-called "yard goods" to length.
  • the precisely defined and unchangeable distance between the stop and the edge of the housing opening results in a precisely defined protruding length of the rod.
  • the specified dimensional relationships ensure that the contact pressure of the rolling elements is distributed over a much greater length of the rod. It was surprisingly found that if the specified minimum values of the dimensional relationships are observed, there is no longer any disruptive deformation of the rod, so that in the case of threaded rods the nuts can easily be screwed onto the threaded rods or tie rods.
  • the individual tie rods can be manufactured at the installation site by sawing off or parting off sections of threaded rods of greater length, known as yard goods. As a result, expensive machining of the drive ends of the threaded rods can be avoided.
  • the object of the invention is a kind of universal tool that can be used both for rods with a cylindrical surface and for threaded rods.
  • FIG. 1 A complete screwing device 1 is shown in FIG. This has a housing 2 with an essentially cylindrical outer surface 3, which merges into a cylindrical surface 5 of smaller diameter via a conical surface 4.
  • the free end of the cylinder surface 5 is at the same time the so-called drive end 6, in which there is a dashed inner square 7 with an edge length of 1/2 inch.
  • Any inner or outer prism can take the place of the inner square, e.g. an external hexagon.
  • the largest part of the length of the housing is taken up by an interior space 8 which ends in a rear end wall 9. At the opposite end of the interior 8 there is a housing opening 10 which is surrounded by an edge 11.
  • the surface lines delimiting the interior run axially parallel, but form so-called ramp surfaces 12, which exert a wedge effect on the rolling elements 13 with respect to the axis AA, which are designed as cylindrical rollers.
  • the rolling elements 13 are guided in a cage 14, the outer and inner surfaces of which are partial cylindrical surfaces, between which receiving pockets 15 for the rolling elements 13 are formed.
  • These receiving pockets 15 are delimited by partial cylindrical surfaces 16, the diameter of which is greater than the diameter of the roller bodies 13 in such a way that the roller bodies 13 can execute radial movements under the action of the ramp surfaces 12 until they rest against the threads of a threaded rod 17th to be brought.
  • the outer circumference of the threaded rod is indicated by the dashed circle 18. This dashed circle 18 corresponds to the nominal diameter of the threaded rod 17th
  • the axial length L A of the interior 8 is shown.
  • the total length of the rolling elements is at least 80% of this axial length L A , which extends from the edge 11 of the housing opening 10 to the end wall 9, which represents the stop for the threaded rod. It can be seen that the interior 8 is closed in the direction of the drive end 6.
  • five rolling elements 13 are arranged at each circumferential point of the cage 14; However, it is possible to provide only three or four rolling elements at each circumferential point of the cage with the same total length, or - in the limit case - only one rolling element of corresponding length, which in turn must be at least 80% of the length L A.
  • the cage 14 is held together with the rolling elements 13 in the interior 8 by an annular disc 19, which in turn is fixed by a locking ring 20. Cage 14 and rolling elements 13 can be removed for cleaning purposes.
  • the cage 14 consists of an annular part 14a and three axially parallel webs 14b extending therefrom, between which the cylindrical rolling elements 13 are mounted in the manner indicated above by means of the partial cylinder surfaces 16.
  • the cage 14 has a coaxial bore 21 which serves for the introduction of the threaded rod 17 (the cage 14 is shown in an upside-down position in FIG. 2).
