Definitions

  • the present invention relates to sockets, and in particular to sockets for tightening, loosening or holding a hexagonal part underneath an equally sized hexagonal nut.
  • top nut and also the bottom nut or the washer have the same hexagonal outer surfaces, in many instances it is difficult to apply the socket with the inner hexagonal opening onto the bottom nut or the washer because the hexagonal profile of the top nut can be circumferentially offset relative to the hexagonal outer profile or the bottom nut or the washer.
  • top nut on the one hand and the bottom nut or the washer on the other hand must be turned relative to one another so that on the top view their outer hexagonal profiles coincide with one another, which is not easy to achieve. Accordingly, it is an object of the present invention to provide sockets for tightening, loosening or holding a hexagonal part underneath an equally sized hexagonal nut, which alleviate the disadvantages of the prior art.
  • the socket is designed in accordance with the present invention, then even if the top hexagonal nut and the bottom hexagonal part are circumferentially offset relative to one another, it is still possible to apply the socket by axially moving it over the top nut and then over the bottom part, so that in the final position the inner opening with the recesses of the socket surrounds the hexagonal outer profile of the bottom part.
  • Figure 1 is a cross-section of a torque wrench with sockets for tightening and loosening of a threaded connector
  • Figure 2 is a section taken along the line I-I of Figure 1 and showing a holding socket in engagement with a bottom part, such as a bottom nut or a washer, in a tightening mode;
  • Figure 3 is a view substantially corresponding to the view of Figure 2 but additionally showing a top nut which blocks the holding socket from removal in an axial direction;
  • Figure 4 is a view substantially corresponding to the view of Figure 3 in which the holding socket is turned so that the top nut no longer blocks the holding socket.
  • Figure 1 shows as an example a threaded connector which is identified as a whole with reference numeral 1, and a tool for tightening or loosening the threaded connector which is as identified with reference numeral 21.
  • the threaded connector has a bolt 2 which is introduced in an object 3 composed for example of two parts to be connected with one another, a hexagonal nut 4 which is screwed on the bolt, and a hexagonal part such as a washer or a bottom nut 5 which is located underneath the nut 4 and between the nut 4 and the surface of the object 3.
  • the hexagonal nut 4 and the hexagonal part 5 are of substantially equal cross-sectional size.
  • the bottom nut or the washer 5 can have an inner surface engaged in the threads of the bolt 2.
  • the holding socket 8 has an upper axial portion 9 which is connected, for example by splines or the like, to an immovable part 10 of the tool 21 and surrounds the rotatable shaft 7.
  • the holding socket 8 has a lower axial portion 11 which is located in the region of the bottom part, such as the bottom nut or the washer 5, and non-rotatably holds the bottom nut or the washer 5. It prevents turning of the bolt 2 and counteracts the reaction forces.
  • the holding socket 8 holds with its portion 11 the bottom nut or the washer 5 so that the latter can not turn, the bolt 2 also can not turn, but only displaces in an axial direction.
  • Figure 2 shows a cross-section of the axial portion 11 of the holding socket 8. It has an inner opening 12 with a plurality of recesses 13 each having at least one flank 14 formed to abut against at least one side of the outer hexagonal profile of the bottom nut or washer 5.
  • the inner opening 12 with the recesses 13 has six radially inner points 15 and twelve outer points 16.
  • Each recess has an outer surface 17 extending between two neighboring radially outer points 16.
  • the inner surface of the opening 12 with the recess 13 is actually formed as a conventional surface with twelve inner recesses (a 12 point surface) in which each second radially inner point 18 is removed.
  • the outer surface of the inner opening 12 with the recesses 13 of the portion 11 of the holding socket 8 is formed so that the holding socket 8 can be placed on the outer hexagonal contour of the bottom nut or the washer 5 not only when the flanks 14 coincides with the corresponding sides of the hexagonal outer profile of the bottom nut or the washer 5 as shown in Figure 2, but also when the flanks 14 are offset in a circumferential direction relative to the corresponding sides of the outer hexagonal profile of the bottom nut or washer 5.
  • the holding socket 8 can be axially moved over the top nut 4 and the lower nut or the washer 5 also when the outer hexagonal profiles of the top nut 4 and the bottom nut or washer 5 are circumferentially offset relative to one another.
  • Figure 2 shows the holding socket 8 during tightening, when the flanks 14 of the opening of the portion 11 of the holding socket 8 abut against the side surfaces of the hexagonal bottom nut or washer 5.
  • Figure 3 substantially corresponds to Figure 2 and additionally shows a view from above on the top nut 4. It can be seen from Figure 3 that when the threaded connector is tightened, it is possible that the top nut 4 does not allow an axial upward removal of the portion 11 of the holding socket 8, since it overlaps the radially inwardly extending points of the portion 11 of the holding socket 8.
