Definitions

  • This invention relates to a dog for a detector switch, for example, a limit switch, which is used to detect a position to which a machine is moved.
  • a conventional dog of this kind which is shown in Figs. 1-3, is made of steel.
  • the dog has in its central portion a through bore b, through which a screw stud a is inserted, the bore b extending in the axial direction of the dog.
  • the dog is further provided with a slit c extending in the same direction as the through bore b and having portions extending above and below the through bore b.
  • a slit portion d of the dog through which the lower portion of the slit c extends to be opened downward, is provided at one side of an outer cir- cumferential surface thereof with a circular sopt-faced bore e and a bolt-inserting bore f, which extend at right angles to the slit c, and which communicate with each other.
  • the other side of the outer circum- ferential surface of the slit portion d is provided with a threaded bore g communicating with the bolt-inserting bore f.
  • the hexagonal rod spanner S can be fitted into only one side thereof, i.e. the side in which the spot-faced bore e is provided. This causes much trouble in the handling of the spanner S.
  • the dog according to the present invention is provided at both sides of an outer circumferential carrying surface of a slit-carrying section 8 thereof with hexagonal spot-faced bores 9, 11 and bolt-inserting bores 10, 12, which extend at right angles to a slit 7, and which communicate with each other, in such a manner that the bores 9, 11 and the bores 10, 12 are symmetrically opposed to each other. Accordingly, either a hexagonal bore-carrying bolt 13 or a hexagonal nut 14 can be inserted or fitted into either the spot-faced bore 9 or the spot-faced bore 11, and the dog can be tightened from either of two opposite directions. This enables setting and adjusting the dog to be done easily in a narrow space, and the efficiency of the operation to be improved.
  • the dog according to the present invention does not require a threaded bore, which is difficult to make in a curved outer circumferential surface, to be provided. This enables the dog to be manufactured simply, and the cost of manufacturing the same to be reduced.
  • Reference numeral 1 denotes a limit switch, 2 a roller for the limit switch, 3 a casing, and 4 a dog body for the limit switch 1.
  • a principal portion 4a of the dog body 4 is made, for example, of a synthetic resin so as to manufacture the dog easily and reduce the weight thereof.
  • An outer circumferential surface of the principal portion 4a is plated, for example, with hard chromium 4b to prevent the portion of the outer surface of the dog which contacts the roller 2 for the limit switch 1 from being worn and the outer surface of the dog from being damaged by sparks during cutting and welding operations.
  • the dog is provided at its central portion with a through bore 6 extending in the axial direction thereof and formed to enable a screw stud 5 to be inserted therethrough, and a slit 7 extending in the same direction as the through bore 6 and consisting of portions extending above and below the through bore 6.
  • a slit-carrying section 8, in which the slit 7 extends opening downward, is provided at both sides of its outer circumferential surface with bolt-tightening and inserting hexagonal spot-faced bores 9, 11 and bolt inserting bores 10, 12, which bores 9, 11 and 10, 12 extend at right angles to the slit 7 and communicate with each other.
  • the bores 9, 11 and 10, 12 are provided Symmetrically opposing each other.
  • one side of the outer circum--carrying ferential surface of the slit -carrying section 8 is provided with a bolt tightening and inserting hexagonal spot-faced bore 9 and a bolt-inserting bore 10 communicating with the bore 9, so that these bores 9, 10 extend at right angles to the slit 7;
  • the other side portion of the outer circumferential surface of the slit-carrying section 8 is provided with a bolt tightening and inserting hexagonal spot-faced bore 11 and a bolt-inserting bore 12 communicating with each other and positioned in symmetric opposition to and shaped identically with the bores 9, 10, respectively.
  • reference numeral 13 denotes a hexagonal bore-carrying bolt inserted into one spot-faced bore 9, and 14 a hexagonal nut inserted into the other spot-faced bore 11 to be screwed to the bolt 13.
  • Figs. 7 and 8 illustrate another example of the present invention, i.e. a disc type dog formed by utilizing the techniques according to the present invention. As is clear from these drawings, the techniques according to the present invention can be applied to various shapes of dogs.

Abstract

Cran d'arrêt pour commutateur de détection, comme un commutateur de fin de course ou autre, où une partie de gorge en fente (8), s'ouvrant sur une gorge en fente (7) communiquant avec un trou traversant (6) à travers lequel est inséré un prisonnier (5), est formée d'un trou hexagonal contrepercé (9) et d'un trou pour boulon (10) traversant perpendiculairement la gorge en fente (7) d'un côté de la périphérie extérieure de la partie de gorge en fente (8), ainsi que d'un trou hexagonal contrepercé (11) et d'un trou pour boulon (12) correspondant symmétriquement aux trous (9) et (10), de l'autre côté de la périphérie extérieure de la partie de gorge (8), rendant ainsi possible l'insertion ou l'engagement d'un boulon dans un trou hexagonal (13) ou avec un écrou hexagonal (14) à partir de n'importe quel trou contrepercé (9) ou (10), ainsi que son serrage.
