JP3108102U - External diameter effective diameter taper screw type embedded nut insertion jig - Google Patents

Abstract

The outer diameter effective diameter taper screw type embedded nut has a press-fitting effect due to the taper screw which is not in the conventional outer diameter screw type embedded nut, and no caulking or adhesive processing after embedded insertion is required. The embedded nut could be pulled back without being unlocked while the embedded nut was locked to the jig.
The guide screw 6B of the locking slide portion of the embedding jig is separated from the slide portion so that a play of about a quarter of a turn is provided in the rotation direction, and a play of about 1 mm can be made in the axial direction when the lock is released. By incorporating such an irregular coupling mechanism, when the guide shaft 2 and the locking slide outer diameter knob are rotated, the outer diameter knob 5A is preceded by rotation so that the jig can be locked or unlocked with respect to the embedded nut. A reliable jig can be provided.

Description

  The present invention can improve the workability and reliability of the work of inserting and embedding embedded nuts to be used for reinforcing or correcting screw holes of light alloys and molded products.

  To insert and embed conventional outer diameter threaded embedded nuts and outer diameter effective diameter tapered thread embedded nuts, hold the nut with a guide screw with abutment, insert it, and caulk or bond the mouth, then pull out the guide screw It was.

There is a guide screw for holding the nut at the tip of the guide shaft integrated with the nut embedding insertion knob, and the lock that slides with the guide screw and the locking screw in the opposite direction by turning the lock knob that slides on the guide shaft An insertion jig that can lock or release the nut to the guide screw has also been developed.
Utility model registration No. 25400115

  The outer diameter effective diameter taper screw type embedded nut has the effect of press-fitting with a taper screw that is not found in conventional outer diameter screw type embedded nuts, and no caulking or adhesive processing after embedded insertion is required, but it is embedded in the insertion jig The embedded nut could be pulled back without being released with the nut locked.

  There is a nut holding guide screw at the tip of the guide shaft integrated with the nut embedding insertion knob, and there is a guide screw for driving the locking slide part and a locking screw in the opposite direction in the middle of the guide shaft. Inside the outer diameter part (knob) of the sliding part for locking, it engages with the locking screw for the guide shaft held by the irregular coupling having a play of about 90 degrees in the rotational direction and having a tapered surface in the axial direction. A guide screw for locking is provided, and when the guide shaft is turned, it slides in the opposite direction to the embedded nut with respect to the guide shaft, and the tip of the locking slide is a locking abutment that locks the embedded nut. And the lock slide outer diameter knob in the same direction so that the embedded nut on the guide shaft end can be locked or unlocked in its holding position. .

  The guide screw of the slide part for locking is separated from the slide part, and there is a play of about 90 degrees in the rotation direction, and a slight taper is provided in the rotation direction in the axial abutment part so that the coupling claw of the guide screw slides When the guide shaft and the locking slide outer diameter knob are rotated in the same direction by being held in accordance with the irregular coupling, the rotation of the locking slide outer diameter knob is slightly advanced so that the guide shaft can be Locking or unlocking is easy and reliable, improving workability and reliability.

  There is an embedded nut retaining guide screw at the tip of the guide shaft integrated with the nut embedding insertion knob, and it drives the locking slide on the guide shaft in the middle part of the jig, opposite to the nut retaining screw. The guide shaft provided with the lock guide screw and the slide slide guide portion are separated from the lock slide portion, and the slide slide guide screw moves in the axial direction with 90 ° play in the rotation direction and a slight taper on the abutment portion of the coupling claw. Combined with a locking slide unit connected by an irregular coupling.

  FIG. 1 is an explanatory view of an embodiment of the present invention, and there is a guide screw (1) for holding an embedded nut (8) at the tip of (2) of a guide shaft integrated with a knob for inserting and inserting a nut (3). In the middle of the guide shaft, there are a holding screw (1) for holding the embedded nut (8) and a locking screw (6A) in the opposite direction for driving the locking slide (7A). (7A) The outer diameter knob (5A) is held by a coupling claw (6C) for irregular coupling having a play of about 90 degrees in the rotational direction and a taper (7B) in the axial contact surface. A locking guide screw (6B) that is screwed into the locking screw (6A) of the guide shaft (2) is provided. By turning the knob (3) of the guide shaft (2), the guide shaft (2) Slide in the opposite direction to the embedded nut (8) The tip of the locking slide (7A) is a locking abutment (4) that locks the embedded nut (8). The guide shaft knob (3) and the locking slide outer diameter knob (5A) are the same. By turning in the direction, the embedded nut (8) held by the holding guide screw (1) at the end of the guide shaft can be locked or unlocked at the holding position.

  FIG. 2 is an explanatory view of the operation of the irregular coupling portion, and a lock guide for driving the lock slide portion (7A) provided on the guide shaft (2) integrated with the nut embedding insertion knob (3). A lock screw (6A) that is screwed to the screw (6B) is provided, and a lock guide screw (6B) that is screwed to the screw (6B) is a coupling claw (6c) and a taper claw (7B) provided on the end surface of the lock slide portion. Therefore, the movement of the locking slide portion (7A) is transmitted. The outer diameter knob (5A) for turning the lock slide is securely fixed to the lock slide by the push screw (5B), and the lock slide (7A) is fixed by the stop ring (5C). It does not fall off from the guide shaft (2). Then, according to the rotational direction (9), the relative positions of the parts at the time of locking and releasing are as follows (5B ') (6B') (6C ') (7B') at the time of releasing.

  There is a possibility that it can be applied to automation of insertion and embedding work of embedding nuts and extraction work.
