- a joint for example, a driving force transmission component or the like
- This is a press-fit joining device that can produce the required products.
- the outer diameters of the respective collet chuck type electrodes increase toward the root direction.
- Each of the ring members has an outer peripheral portion having outer peripheral tapered portions 160c and 170c, and the inner periphery corresponding to the outer peripheral tapered portions 160c and 170c of each collet chuck type electrode. Since the taper portions 161a and 171a are provided (see FIGS.
- each ring member is moved (slid) toward the root direction of each collet chuck type electrode to tighten each collet chuck type electrode from the outer peripheral side.
- the first ring member 161 is attached to the shaft receiving plate 131 (the first ring mounting bracket 163 and the first air cylinder mechanism 164).
- the second ring member 171 is attached to the sub platen 142 (the second ring attachment fitting 173 and the second attachment fitting 173 and the second attachment fitting 173). Since it is attached (movable along the vertical direction) to the second ring member holding bracket 172 attached (via the air cylinder mechanism 174), the outer diameter reference of the workpiece (first part and second part)
- the workpiece can be tightened uniformly and quickly.
- by combining the first ring member holding metal fitting and the second ring member holding metal fitting with the air cylinder mechanism it is possible to significantly reduce the time for performing the entire press-fit joining process as compared with the case of screw tightening.
- the first collet chuck type electrode 160 has an angle of the outer tapered portion 160c with respect to the axis of the first collet chuck type electrode 160 within a range of 1 ° to 70 °.
- the second collet chuck type electrode 170 has an angle of the outer peripheral tapered portion 170c with respect to the axis of the second collet chuck type electrode 170 within the range of 1 ° to 70 °.
- 161 and the second ring member 171) are moved (slided) when moving (sliding) toward the root direction of each collet chuck type electrode (first collet chuck type electrode 160 and second collet chuck type electrode 170). It is possible to efficiently convert the operation into a workpiece clamping operation.
- the first ring member 161 and the second ring member 171 are both metal materials (baked) that are harder than the first collet chuck type electrode 160 and the second collet chuck type electrode 170. Since each ring member (the first ring member 161 and the second ring member 171) is made of steel, etc., the base of each collet chuck type electrode (the first collet chuck type electrode 160 and the second collet chuck type electrode 170). By moving (sliding) in the direction, each collet chuck type electrode is securely clamped from the outer peripheral side, and each work (first member 10 and second member 20) is gripped (clamped) by each collet chuck type electrode. ).
- each ring member (the first ring member 161 and the second ring member 171) has the cooling medium flow path inside (see FIGS. 8 and 9).
- the press-fitting device 100 causes a current to flow between the first member and the second member while flowing the cooling medium through the cooling medium flow path 161b of the first ring member 161 and the cooling medium flow path 171b of the second ring member 171.
- the two collet chuck electrodes can be cooled while using the two collet chuck electrodes having the cracked structure (first collet chuck electrode and second collet chuck electrode division).
- the lifetime of these two collet chuck electrodes can be extended.
- overheating of the collet chuck type electrode can be efficiently prevented even when compared with a conventional cooling mechanism (for example, a mechanism for cooling the electrode through the pipe of the cooling water through the platen through the base plate).
- a conventional cooling mechanism for example, a mechanism for cooling the electrode through the pipe of the cooling water through the platen through the base plate.
- the lower platen 110, the upper platen 120, the shaft receiving plate 131, the shaft fixing plate 133, and the sub platen 142 are made of a nonmagnetic metal material. Even in the presence of a strong magnetic field generated in the transformer (see FIG. 14D), these members may be easily magnetized (unlike using a magnetic metal material for these members). Disappear. As a result, it is possible to extremely reduce the possibility that the press-fitting and joining apparatus will malfunction, and it is possible to prevent the dust such as iron powder from being adsorbed to these members.
- the spacer 143 is fixed to one of the sub platen 142 and the upper platen 120 and is not fixed to the other. Therefore, it is not affected by the mouth opening phenomenon caused by the C-shaped frame (see FIG. 14C).
- the second collet chuck type electrode 170 can be replaced for each part separated by each slit, and the second member gripping chuck can be replaced. Since the member 170h is included, even if the chuck part for gripping the workpiece among the collet chuck type electrodes deteriorates, at least the second collet chuck type electrode 170 is not replaced with the entire collet chuck type electrode. Since only the chuck members need to be replaced, the manufacturing cost can be reduced.
- the spacer 143 that is fixed to the sub-platen 142 and not fixed to the upper platen 120 is used as the spacer.
- the present invention is not limited to this.
- a spacer that is fixed to the upper platen 120 and not fixed to the sub-platen 142 may be used.

- a spring having a function of giving a repulsive force to each of the plurality of bearing mechanisms 141 instead of the air cylinder mechanism (third air cylinder mechanism 150) or in addition to the air cylinder mechanism (third air cylinder mechanism 150).
- a coil may be interposed between each slide shaft 132. In this case, when the sub platen structure 140 is pushed down, the spring coil may have a function of applying a repulsive force to the push-down operation of the sub platen structure 140.
- the second member 20 including only the shaft portion is used as the second member, but the present invention is not limited to this.
