Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adapter used for connecting a torque wrench and a torque wrench checker when checking a preset type torque wrench.

[0002]

[Prior art]

 For example, as shown in FIG. 1, in order to measure the torque value of a preset type torque wrench 1 with a wrench, a torque wrench and a spanner of 1 are provided on the hexagonal protrusion 3 for engaging the torque wrench provided on the torque checker 2. The torque wrench checker 2 indicates the torque value at the time of the operation of the toggle in the torque wrench 1 caused by engaging the part 4 and then rotating the handle part of the torque wrench in the tightening direction. Some are detected by the value.

[0003]

[Problems to be solved by the device]

 However, since the shape and size of the hexagonal adapter 3 for engaging the torque wrench fitted and held in the torque wrench checker 2 are constant, the spanner portion 4 of the torque wrench engaged with the hexagonal projection 3 is formed. Since the size is automatically determined, the torque wrench checker 2 can only check the torque wrench 1 having the wrench part 4 of a certain size, and the torque checker of one model with the wrench part 4 of a different size. It was impossible to check many types of torque wrenches.

Therefore, conventionally, in order to check the torque of various torque wrenches, it is necessary to prepare various torque wrench checkers in advance, or to prepare adapters of various diameters that can accommodate torque wrench spanners of various sizes. In addition, since the adapters must be replaced for each torque wrench with a different spanner diameter, the measurement workability is poor, and the inconvenience of having to manage each adapter is inconvenient. there were.

[0005]

[Means for Solving the Problems]

 The present invention has been made in view of the conventional inconvenience, and has developed an adapter that can be used in common with various types of torque wrenches, and by using this adapter, a spanner part of various sizes can be used with a certain torque wrench checker. Another object of the present invention is to provide an adapter for a torque checker that can easily perform a torque check of a torque wrench having a.

【Example】

 The present invention will be described in detail below based on the embodiment shown in the drawings. The same parts as those of the structure of the present embodiment and the structure described in the conventional example are designated by the same reference numerals as those used in the conventional example. The structural description of the structural part is omitted.

That is, since the present invention is characterized by the adapter 6 that can be engaged with the measuring shaft 5 of the torque wrench checker 2, the structure of the adapter 6 will be described below.

The adapter 6 has a structure shown in FIGS. 2 and 3, and 7 is an angular drive 8 fitted to the measuring shaft 5 of the torque wrench checker 2, and is integrally formed at one end of the angular drive 8. Is a main adapter having a flange portion 9 having a groove 9B formed in the diametrical direction and a screw hole 10 formed on the central axis of the flange portion 9 and the corner drive 8.

Reference numerals 11, 12, 13, and 14 are sub-adapter assembled to the main adapter 7, and these sub-adapter 11, 12, 13, and 14 have different outer diameters as shown in FIG. Each of the sub adapters 11, 12, 13, 14 has a ridge 11A, 12A, 13A, 14A extending in the diametrical direction, and the other side thereof has any of the above ridges. Are also formed with diametrical recesses 11B, 12B, 13B, 14B.

Further, a screw through hole 15 is formed on the central axis of each sub-adapter.

The adapter 6 of this embodiment is made by combining the main adapter 7 and the sub-adapters 11, 12, 13, 14 and is provided on the flange 9 of the main adapter 7 as shown in FIG. The convex strip 14A of the sub-adapter 14 is engaged with the concave groove 9B, the convex strip 13A of the sub-adapter 13 is engaged with the concave groove 14B of the sub-adapter 14, and the sub-adapters 12, 11 are successively engaged in the same manner. To combine.

Next, at the center of the sub-adapter, the mounting screw 16 is inserted into the through hole 15 and the mounting screw 16 is screwed into the screw hole 10 of the main adapter 7, so that the main adapter 7 has several sub-adapters. It is completed by joining 11, 12, 13, and 14 together.

In the embodiment described above, four sub-adapters are prepared, and these sub-adapters are formed into a skewered shape with the mounting screws 16 and integrally screwed to the main adapter 7. The number is not limited, and may be, for example, 4 or less or 4 or more, and the outer diameter of each sub-adapter may be selected as required.

It is a matter of course that the length of the mounting screw 16 must be selected and used according to the number of sub adapters used.

As described above, in the present embodiment, the main adapter 7 having the angular drive 8 that can be engaged with the drive shaft of the torque wrench checker is coaxially coupled with a plurality of sub adapters of different sizes. Moreover, since these sub-adapter and the main adapter 7 are integrally connected by the mounting screws, the adapter can be combined with the main adapter by combining a plurality of sub-adapter of the size required by the user. Since it can be used as an adapter, by fitting this adapter to the measuring shaft of the torque checker, it is possible to easily perform the torque measurement work of the torque wrench that can handle torque wrench spanners of various model sizes. is there.

Further, the combination and the number of sub-adapter can be freely selected, which greatly improves the torque check workability of each torque lench.

[0017]

[Effect of device]

 As described above, the present invention has the square drive 8 fitted to the measuring shaft 5 of the torque wrench checker at one end, and the sub-adapter fitting groove 9B at the other end. On the central axis, a main adapter 7 having a screw hole 10 is provided, and a ridge capable of engaging with the fitting groove is provided on one side surface, and a groove having a size with which the ridge can be engaged is provided on the other side surface. A plurality of sub-adapter 11, 12, 13, and 14 which are formed and have various sizes for holding spanners of various sizes and have a mounting screw insertion hole 15 in the center, and are inserted into the mounting screw insertion holes 15 of these sub-adapter. In addition, since it is an adapter including a mounting screw 16 for screwing these sub-adapter to the main adapter, it is possible to combine a plurality of sub-adapter of the size required by the user. Since it can be combined with the adapter to be used as an adapter, by fitting this adapter to the measuring shaft of the torque checker, you can easily perform the torque measurement work of a torque wrench that can handle torque wrench spanners of various model sizes. is there.

In addition, the combination and the number of sub-adapter can be freely selected, and this has the effect of significantly improving the torque check workability of various torque lents.
