部3を所要の締付圧で締着することができる。Fig. 2(a) and (b) Fig. 3 shows an embodiment of the iron core tightening device of the present invention, and the parts indicated by reference numerals 1.2.3.4.11.13 are shown in Fig. 1(a) and (b). The clamps 11 each have a mounting portion 11a on one side in the yoke width direction that is inclined outward at a predetermined angle θ with respect to the yoke clamping surface A.
is the provision. Further, on the yoke side of the crossbar 13 connected to this clamp 11, by utilizing the space between this and the yoke stepped portion 3a, a screw seat 15 with an inclined end face 15a corresponding to the mounting portion 11g is protruded by welding, Screw hole 16 of this screw seat 15
The mounting part 11a of the clamp 11 is fixed to the end face 15a provided with a bolt 17, and the yoke part 3 is moved in the stacking direction using a component force Ps (see Fig. 3) of the clamping force P acting on the clamp 11. By selecting appropriate values for the strength of the bolt 17 and the angle of inclination θ of the clamp attachment portion, the yoke portion 3 can be tightened with the required tightening pressure.

的に簡素化され、工数も低減する利点がある。With the above configuration, the steel plate of the core yoke part 3 can be
(Since the yoke part 3 can be tightened in the stacking direction without creating punched holes for studs with !, it is possible to prevent deterioration of the magnetization characteristics of the core. Also, since there is no need to punch holes in the yoke part, the structure It has the advantage of being simplified and reducing the number of man-hours.

できる。In the embodiment shown in FIG. 4, the inclination angle θ of the protruding portion 11m with respect to the yoke tightening surface of the clamp 11 is the screw seat mounting end surface 15a.
The inclination angle θ1 of θ1 is appropriately increased. In this way, when the swivel clamp 11 is attached to the screw seat 15, the clamping pressure of the yoke part 3 is further increased due to the elastic deformation of the clamp due to the angle difference between the two.9 To improve the tightening performance by -18. Can be done.
