Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a rivet continuous body consisting of a large number of rivets connected in succession, and drives the rivets one by one so that the mounting body, for example, is attached to a plate etc. in a superimposed manner. The present invention relates to a rivet driving tool that can connect the rivet and collect the remaining part of the rivet continuous body after driving the rivet in a continuous state.

As such a tool, Japanese Patent Publication No. 55-46775 discloses a method and device for locking a pipe stud in a connected manner with a locking plate. According to this known example, an assembly formed by connecting a large number of tubular rivets is used, but in order to drive six rivets, the rivets are torn off one by one from the assembly, and then loaded into a piston-type rivet locking means. After driving the rivets, the shafts that are no longer needed are cut off and the cut shafts are discharged individually. For this reason, the six rivets from the assembly are handled separately, which not only complicates the process and structure of the tool, but also causes unnecessary shafts to be scattered, making collection and disposal very troublesome. Met.

SUMMARY OF THE INVENTION Therefore, the present invention provides a rivet driving tool that can drive rivets in a continuous state, and can collect the remainder of the rivets in a continuous state.

Hereinafter, one embodiment of the drawings will be explained. The rivet used in the present invention was disclosed in Japanese Patent Application No. 56-1943 by the present applicant.
68 (Japanese Patent Application Laid-Open No. 58L97441), detailed descriptions in Figures #I4 to 13 are used as is, but of course,
Not limited to this, a comb-shaped long metal plate having a similar long continuous piece and comb teeth that protrude integrally in a T-shape at regular intervals from the continuous piece and have a weak part in the middle of the length. and,
A plastic rivet shaft is formed by insert molding on the outside of one of the comb teeth of the metal plate, and the end facing the continuous piece has a flange extending from the outer periphery.The rivet shaft is inserted into the hole in the workpiece. By pushing the flange and pushing out the rivet shaft through the comb teeth, the rivet shaft expands under the workpiece and fixes the workpiece between it and the lower surface of the flange, and at the same time, the comb teeth are inserted into the weakened part located in the rivet shaft. Any rivet continuum that can be torn apart will suffice.

Here, FIGS. 1 to 5 show the above-mentioned patent application No. 56-194368.
The outline will be described by showing some of Figures 1 to 13 of the issue.
For details, please refer to the above-mentioned earlier application.

The rivet continuum consists of a metal plate and a rivet shaft 3 formed by insert molding on the metal plate.

The metal plate 2 consists of a long continuous piece λα and a comb tooth b protruding from the continuous piece 2α at regular intervals in a T-shape and having a fragile part in the middle of its length, and the rivet shaft 3 has a comb tooth 2b.
The rivet shaft 3 is formed separately from the continuous piece b, and the weakened portion d is located in the rivet shaft 3. Each rivet shaft 3 has a flange 3' projecting from the outer periphery at the end facing the continuous piece λα, and in this example, the rivet shaft 3 has a vertical hole j in which the comb teeth 2b are exposed in the middle part facing the rivet shaft 3. The rivet shaft 3
The cylindrical upper part 3α and lower part 3b are connected by side parts sl and sl on both sides of the vertical hole j. still.

The comb teeth 2b are provided with triangular holes close to both side edges, and both sides of the holes are made into weakened parts, but of course the present invention is not limited to this.

Further, the continuous piece α is provided with weak connecting portions 6.6 on the left and right sides for each piece 2a', and can be bent or separated for each piece 2a'. Then, a circular pin hole 7 was bored in the approximate center of the one piece α', and the upper edge was bent in half the width alternately into an inverted shape. Wing piece lr.

It is equipped with l.

By this rivet continuum l, the upper and lower two panels P1
In order to bond y p in a polymeric manner, pass the rivet shaft 3 through a series of holes in both panels, and then connect the upper panel P,
The lower surface of the flange 3' is brought into contact with the upper surface, and in this state, pressure is applied relatively to the rivet shaft 3 or the comb teeth b to push the rivet shaft 3 out of the comb teeth 2b, or the comb teeth 2b are pushed out from the rivet shaft 3. Pull it out. As a result, each side rl, sl of the rivet shaft 3
is bent outward in a dogleg shape (Fig. 3), and finally buckles in a folded manner under the lower panel P, joining the panel PI * p in a polymerized state between it and the lower surface of the collar 3'. Figure 4),
Eventually, the comb teeth 2b will be torn to pieces at the weak parts. The weakened portion DA is designed so that it is not torn off on the collar 3' of the rivet shaft 3, but within the rivet shaft. In addition, when holes and depressions 9 are formed in the comb teeth 2b below the fragile portion V and the rivet shaft 3 is molded, the plastic fills the holes and depressions, and the plastic fills the holes and depressions 9 below the weak portion DA of the comb teeth 26. The dovetail should ensure that a portion remains in the rivet shaft 3.

Now, it is preferable to provide the comb teeth 2b, which form the rivet shaft 3 of the rivet continuous body l by insert molding, in close contact with the continuous piece -α in order to avoid wasting the material of the metal plate λ. two rivet shafts on panel P,
, P, it is necessary to cut the continuous piece in the middle of the comb teeth, since the neighboring rivet shafts will get in the way. Furthermore, after the panels are joined, the portion above the weakened portion of the comb teeth and one piece of the integral continuous piece attached to the upper end thereof will be scattered.

Therefore, in the present invention, the rivet continuum is connected in a series.
The rivet shafts were loaded, and the rivet shafts were inserted one by one into the holes of the panels to be joined to perform the joining, and the parts above the weakened part of the joined comb teeth were attached to a series of continuous pieces. a guide groove in which a rivet driving tool guides the continuous piece of the rivet continuous body, and a feeding device that advances the rivet continuous body to the interval between the comb teeth within the guide groove; In connection with the feeding operation of the feeding device, the comb teeth of the rivet shaft that stops at the driving position in the guide groove are bent and the direction is changed from that of other rivet shafts, and the direction is changed by the direction changing device. A pressure device presses the collar of the changed rivet shaft and pushes the rivet shaft out of its comb teeth, and a primary feeding device feeds the rivet continuous body, which is bent by a direction changing device at the driving position to change its direction.

A male thread is formed on one end of the feed lever 13, which is screwed onto the female threaded portion Jlb of the ratchet holder 31 to fix it therein, and a fitting groove into which the inside lever is fitted is formed at one end of the bushing lever/1I (D). One end of the inside lever n may be fitted into the fitting groove, and the bushing lever/II may be fixed to the inside lever n by inserting a series of pins from the outside of the bushing lever/4.

In order to use the tool 10 configured in this manner, it is first necessary to load a continuous rivet into the guide groove l of the tool IO.

To load the continuous rivet l into the guide groove 16, one end /l (E, that is, the wing part &, 'f of the continuous piece α from the inlet side of the guide groove /6 and the lateral groove /l of the guide groove 16) Together with M, the continuous piece −α located at the beginning of the rivet continuum /
It is sufficient to insert the pieces 2a' into the guide groove 16 in sequence, and feed them until the leading piece λα' engages with the guide groove 16 feeding device. When the rivet continuous body l is fed in, the rivet continuous body l becomes fixed at the position where the feed pin 32 of the quadrupler 19 is fitted into the pin hole 7 of the leading piece α'.

Next, the feed lever 13 is idle-feeded twice to load the leading rivet shaft 3 into the pusher λl (the first
Figure 9(a)). When the feed lever 13 is first rotated from top to bottom, the parallel 30 engages with the ratchet teeth 23c, and the rotor 12 rotates approximately 45 degrees counterclockwise via the rotating shaft blade, and the leading one-piece α' rotates in two rows. A bent part 16 which is bent from the connecting part 6 with the piece J (1') and has a guide groove l≦
1! sent out along. In other words, the feeding pin n of the stomach-like shape engages the bottle hole 7 of the leading piece λα′, and the scrap-like convex portion/9m of the rotor 19 engages the rear end of the comb tooth λα located at the leading end, and both work together to send out the first piece, and
Sequentially, the next feed pin n and scrap-like protrusion/de e are #! It engages with the second row piece λα'. During this rotation, the comb teeth 2b located at the top are tapered by a portion of the front part iib of the rotor holder it.
α, and bend the leading comb tooth 2b slightly outward with respect to the guide groove 16 (FIG. 11).

Next, when the feed lever 13 is rotated from the bottom to the top,
The ratchet mechanism JtO is idle-feeded, and then the feed lever 1
When the 3 is rotated from top to bottom, the 4-tall will further rotate about 45 degrees counterclockwise. This rotation causes the tip piece 2a to
' is further sent out along the bending part /6m of the guide groove 16, and the leading comb tooth b is bent by the taper part α of the frontal part /Ib and is paired with the guide groove 16. Bend approximately 90 degrees and fit into the receiving groove 2j of the guide portion 17.
It enters inside and stops at the driving position. At this time, the leading comb tooth 2b is fitted into the push percolator groove IIOα.

Next, in order to drive the leading rivet shaft 3, the rivet shaft 3 is passed through a series of holes formed in the two panels, and the bushing lever 14c is gripped. By operating the bush lever /<<, the bush par 27 moves forward via the inside lever n against the bias of the spring co. As the pusher 21 moves forward, the pusher J/ moves toward the rivet shaft 3 with the comb teeth 2b sandwiched in the kerf QOα of the pusher J/, and the pusher 21
The outer surface of the bent portion aO contacts the collar 3' of the rivet shaft 3. When the pusher J/ moves forward, the rivet shaft 3 is pushed forward in the axial direction by its outer surface. That is, since the collar 3' of the rivet shaft 3 is pressed against the panel, a force acts on the rivet shaft 3 so as to pull out the comb teeth 2b. As a result, each side s of the rivet shaft 3
1 and f begin to expand outwards, expand sufficiently, and finally buckle under the panel in a folded manner to join the panel in a superposed state with the lower surface of the collar 3'. Eventually, the bush spar λl stops at the most advanced position, and near the most advanced position, the comb teeth 2b are torn off from the weak part DA, and the part of the comb teeth above the weak part DA attaches to a series of continuous pieces -α. It remains (Part 1)
Figure 9(b)). When the finger is removed from the bushing lever /l, the bushing lever J/ is pushed back by the force of the spring r and returns to its original position. When Bushu Par, 2/ retreats, the rest of the bent comb tooth b is
/ comes into contact with the taper ψOc, is bent to the opposite side, and is slightly corrected (Fig. 19(C)). Next, when rotating the feed lever 13 from top to bottom in order to load the rivet shaft 3 located in the second row into the push bar col,
The remaining part of the bent comb teeth 2b located at the top comes into contact with the inclined part 25α of the receiving groove 3 of the guide part 17, and the inclined part 21
It is bent along the direction a, forms a straight line with the continuous piece α, and is pushed into the guide groove /6. Then, by repeating the above operation, the remaining part of the comb teeth remains attached to the continuous piece, and the other end of the guide groove/4 is successively
That is, after driving the rivet shaft 3, which is located at the rearmost position after moving toward the outlet side, the feed lever 13 is idle-feeded several times, and the rotor 1 feed bin 3λ is located at the rearmost position. The piece 2α' is engaged and disengaged from the bottle hole 7, and the continuous piece becomes released within the guide groove 16. Therefore, by pulling out the continuous piece α from the other end of the guide groove/6, the part above the weak part of the joined comb teeth b can be collected in a continuous state while attached to the series of continuous pieces. .

Further, in the present invention, each lever is operated by hand ulTt=, but it is not limited to this.
As shown in Figure 1 and subsequent figures, fluid pressure such as air pressure may be used.

According to this embodiment V, the main body portion 10' is almost the same as that of the above embodiment. The drive piston mechanism for sliding the pusher shown in the above embodiment, the feed piston mechanism for rotating the rotor via the link mechanism movement and the ratchet mechanism shown in the above embodiment, and the operation of the push button 1j. The control valve II6 is operated by the control valve II6, and is communicated with the control valve II6 as shown in FIG.

The valve operates each piston with fluid pressure, here pneumatic pressure, as follows.

Compressed air from a near compressor etc. comes to the nipple 7 installed inside the handle part/2', from here it is supplied to the operating valve lI6 by the piping supply circuit, and then passes through the circuit to the driving cylinder of the driving piston box. It is guided to the left chamber of the piston t, passes through the circuit 0 from the groove getter α provided in the piston rond of the driving piston p, enters the upper chamber of the feed cylinder jO of the feed piston, and stops there.

In this state, when the push button j is pushed against the spring xi, the operating valve % is switched, the circuit that is in the operating valve is connected to the circuit in the valve chamber, and the circuit is branched to the left and right. 1st branch circuit E
The air that flows into the right chamber of the driving cylinder a moves the driving piston p to the left. This operation is interlocked with the bushing bar and corresponds to the forward direction of the bushing bar.

On the other hand, the air branched from the circuit and flowing into the second branch circuit r flows into the lower chamber of the feed cylinder SO and moves up the feed piston cup. The rise of this feed piston is caused by link mechanism 4.
', 7f- is transmitted to the ratchet mechanism, but if this rotation direction is matched to the idling direction of the ratchet mechanism,
The rotating shaft does not rotate and the rotor does not rotate.

After the rivet driving operation is completed.

When you release your finger from push button +1, operation valve II6 springs! 1 is pushed back to its original position, the operating valve lI4 is switched, enters the left chamber of the driving cylinder U from circuit B, and moves the driving piston to the right. This action causes the bush bar to retreat and return to its original position. And when the driving piston erosion reaches the right end, groove 4I? Via α, the left chamber of the driving cylinder U communicates with circuit C, and air flows through circuit 0. The air flowing from circuit C enters the upper end of the feed cylinder jO and moves down the feed piston cup. The lowering of the feed piston is transmitted to the ratchet mechanism via the link mechanism q, and the powe engages with the ratchet teeth to rotate the rotary shaft, causing the seater to feed the rivet.

Therefore, by inserting the rivet continuous body into the guide groove, engaging the continuous piece located at the top with the four-way bar, and pressing the push button 4Zj several times to perform a blank drive, the first rivet shaft is loaded into the bushing bar. .

After that, you can drive one rivet each time you press the push button, up to the last rivet shaft. After driving the last rivet shaft,
Push the push button II several times and press it blankly to disengage the continuous piece from the rotor, and then pull out the part above the weak part of the joined comb teeth from the guide groove while keeping it attached to the continuous piece. In the present invention, the guide groove is bent into a substantially U-shape, but the guide groove is not limited to this and may be straight. Furthermore, an auxiliary holder containing a spiral series of rivet bodies connected in series may be attached to the inlet of the guide groove, so that a long continuous rivet body can be supplied.

In summary, according to the present invention, it is possible to load a continuous series of rivets into one continuous ball, and to perform the joining by inserting the rivet shaft one by one into the hole of the panel or the like to be joined, and to perform the joining. The parts above the weak part of the comb teeth are attached to a series of continuous pieces, which can be easily recovered once they are scattered.
The effort required to collect and dispose of unnecessary parts of the comb teeth is significantly simplified.

In addition, when driving a rivet shaft, the comb teeth of the rivet shaft are bent and the direction is changed from that of other rivet shafts before driving, so the rivet continuous body used in the tool of the present invention is The comb teeth for molding the rivet shaft using insert molding can be provided closely to the continuous piece7.
Therefore, this is not only preferable in terms of eliminating waste of metal plate material, but also enables driving of a large number of rivet shafts even if the guide groove of the tool is short.
