Description

  The present invention relates to a temporary fixing tool for a workpiece, and in particular, the protrusion length from the workpiece is reduced during temporary fixing so as not to interfere with the processing machine, and the workability of the processing machine can be extremely improved. The present invention relates to a temporary fastener for a workpiece that is possible and does not cause a positional shift between a plurality of workpieces to be temporarily fixed.

  Conventionally, in assembly work such as assembling two workpieces integrally, as a temporary fastener for temporarily joining the two workpieces, for example, a metal columnar shape called Creco is known. ing. And, for example, a plurality of holes opened through the two overlapped workpieces are provided at appropriate intervals, and crecos are respectively inserted into the holes, and the upper surfaces of the two workpieces overlapped by the crecos. And the lower surface are temporarily fixed. At the time of temporary fixing, the cleco protrudes from the insertion side, that is, the upper surface of the work by about 40 mm or more. When the two workpieces are assembled together, for example, by rivet fastening after the temporary fixing, first, a plurality of rivet holes are opened by a processing machine for rivet hole opening between the insertion positions of each creco. Done. At this time, the processing machine opens the rivet hole while moving a position about 15 mm away from the upper surface of the workpiece. For this reason, since the creco interferes with the processing machine at the insertion position of the creco, the rivet hole is formed with respect to a plurality of required positions between the insertion positions of the creco while sequentially removing the creco as the processing machine moves. Opening is performed. In addition, a positioning pin is inserted between the two workpieces separately from the creco so as not to cause a positional shift between the two workpieces.

  Furthermore, as a conventional technique for integrally binding a plurality of members, for example, the following insulation lock is known. This insulation lock is provided with a rectangular protrusion on one end of a flexible band-shaped body made of a synthetic resin material having a required width and length, and one surface of the flexible band-shaped body has its longitudinal length. Locking projections are formed at a predetermined pitch along the direction. The rectangular convex portion is formed with a locking hole through which the free end of the flexible band-shaped body is inserted when the flexible band-shaped body is wound around the object to be bound in a loop shape. A locking claw locked to the locking projection is formed movably. The locking claw allows movement of the flexible strip-shaped main body into the locking hole in the insertion direction, and prevents movement of the flexible strip-shaped main body in the direction opposite to the insertion direction. Then, while winding the flexible belt-like body around the base of the pachinko machine or the like and the circuit board in a loop shape, the free end of the flexible belt-like body is inserted into the locking hole, and the locking protrusion is engaged with the locking claw. The base and the circuit board, which are a plurality of members, are integrally bundled together (for example, see Patent Document 1).

Japanese Patent Application Laid-Open No. 2005-80830.

In the prior art in which temporary fixing is performed with the cleco, the creco protrudes from the upper surface of the workpiece by about 40 mm or more. During operation, the creco interferes with the processing machine at the cleco insertion position. Therefore, in the vicinity of the insertion position of the creco, the cleco is removed while stopping the processing machine each time, so the workability is extremely poor. Further, since Creco is made of metal, there is a risk that the work may be damaged depending on the material of the work. Further, in order to prevent a positional shift between the two workpieces, it is necessary to insert a positioning pin different from the creco between the two workpieces.

  On the other hand, the insulation lock described in Patent Document 1 is obtained by winding a flexible strip-shaped main body around a plurality of members such as a base body and a circuit board in a loop shape, and integrally binding the plurality of members. There is no concept and function of temporarily fixing a plurality of members after positioning them between them.

  Therefore, the protrusion length from the workpiece during temporary fixing is reduced to prevent interference with the processing machine, and it is possible to respond freely to changes in the thickness (grip length) of multiple workpieces to be temporarily fixed. There is a technical problem to be solved in order to prevent misalignment between a plurality of workpieces without requiring pin insertion, and further to prevent damage to a workpiece to be temporarily fixed. It aims at solving this subject.

  The present invention has been proposed in order to achieve the above-described object, and the invention according to claim 1 is characterized in that a plurality of workpieces are opened through a plurality of workpieces while the positional relationship between the plurality of workpieces is maintained at a predetermined positional relationship. And a hooking portion having a width larger than the diameter of the common insertion hole is formed at the insertion tip, and one side surface has an appropriate pitch along the longitudinal direction. A long plate for insertion made of a flexible material having a plurality of locking projections, a guide main body having an outer peripheral surface corresponding to the inner peripheral surface of the common insertion hole, and one end of the guide main body A peripheral hooking portion formed and in contact with the periphery of one opening of the common insertion hole, and an insertion hole that is opened through the guide main body portion and the peripheral hooking portion and through which the long plate for insertion is inserted. Positioning guides and engagements locked by the locking projections A claw and a fitting member that is fitted into an extra insertion length portion of the insertion long plate body, and the insertion long plate body is movably inserted into the insertion hole in the positioning guide. In addition, the guide main body portion of the positioning guide faces the common insertion hole, and further, the hooking portion of the long plate for insertion bends in the width direction and penetrates the common insertion hole to protrude from the common insertion hole. In a state where the original width has been restored, the fitting member is fitted into the extra insertion length portion of the long plate for insertion, and the fitting member is brought into contact with the peripheral latching portion of the positioning guide. By pulling back the end of the extra insertion length portion while being pushed in, the engagement claw in the fitting member is engaged with the engagement projection in the insertion long plate body, and the peripheral engagement portion is the common insertion portion. Around one opening of the hole The plurality of workpieces are temporarily coupled by closely contacting and the latching portion being latched on the other peripheral portion of the common insertion hole, and the positions of the plurality of workpieces in the guide main body portion of the positioning guide There is provided a temporary fastener for a work in which the relationship is maintained in a predetermined positional relationship.

According to this configuration, when a plurality of workpieces are temporarily fixed, the insertion long plate member is movably inserted into the insertion hole in the positioning guide, and the insertion length is formed wider than the diameter of the common insertion hole. The latching part in the plate is inserted into the common insertion hole together with the guide main body part. At this time, the latching portion bends in the width direction and penetrates the common insertion hole, and returns to the original width at the protruding portion from the common insertion hole. In this state, the fitting member is fitted into the extra insertion length portion of the long plate for insertion. The fitting member is allowed to move without the locking claw being locked by the locking projection with respect to the movement toward the peripheral latching portion side in the positioning guide, and for the movement in the opposite direction, The locking claw is locked by the locking projection, and the movement is prevented. Therefore, by pulling back the end portion of the extra insertion length portion while pushing the fitting member toward the peripheral latching portion side, the latching claw in the fitting member is latched by the latching projection in the long plate for insertion. Then, the peripheral latching portion closely contacts the periphery of one opening of the common insertion hole, and the latching portion on the protruding portion side that has returned to the original width is latched on the other peripheral portion of the common insertion hole. As a result, a plurality of workpieces are temporarily joined and temporarily fixed, and at the same time, the positional relationship between the plurality of workpieces is a predetermined position in the guide body portion having an outer peripheral surface shape corresponding to the inner peripheral surface shape of the common insertion hole. By maintaining the relationship, positional deviation between the plurality of workpieces is prevented. At the time of this temporary fixing, an insertion extra length portion of the long plate for insertion and a fitting member fitted to the extra insertion length portion protrude from the surface portion of the workpiece. However, the height of the fitting member can be about several mm, and unnecessary portions of the insertion extra length portion made of a flexible material can be easily cut with a nipper or the like. Therefore, the protrusion length of the temporary fastener to the surface portion of the workpiece can be set to about 10 mm or less, and interference with a processing machine such as rivet hole opening is prevented.

Compared with the case of contacting the periphery, the contact area increases, and a plurality of workpieces can be firmly temporarily joined.

According to the first aspect of the present invention, the positional relationship between the plurality of workpieces is held at a predetermined positional relationship in the guide main body at the time of temporary fixing, and the plurality of workpieces are not required to be inserted without positioning pins. Misalignment can be prevented. Moreover, the protrusion length of the temporary fastener to the workpiece surface portion can be set to about 10 mm or less, and interference with a processing machine such as rivet hole opening can be prevented. Therefore, there is an advantage that the workability of the processing machine can be extremely improved.

  In addition to the effect of the invention described in claim 1, the invention according to claim 2 further prevents the damage to the work from the fact that the long plate for insertion including the latching portion is in elastic contact with the work. There is an advantage that you can.

  The invention described in claim 3 has the advantage that, in addition to the effect of the invention described in claim 1 or 2, it is possible to freely cope with a change in the total thickness (grip length) of a plurality of stacked workpieces. is there.

And the fitting member is inserted into the positioning guide. By pulling back the end portion of the extra insertion length portion while being pushed so as to come into contact with the peripheral latching portion, the engagement claw in the fitting member is engaged with the engagement projection in the long plate for insertion. The peripheral latching portion is in close contact with the periphery of one opening of the common insertion hole and the latching portion is latched on the other peripheral edge of the common insertion hole so that the plurality of workpieces are temporarily In addition, the positional relationship between the plurality of workpieces is maintained in a predetermined positional relationship by the guide main body portion in the positioning guide.

A preferred embodiment 1 of the present invention will be described below with reference to FIGS. First, the workpiece temporary fastener will be described from its component configuration. In FIG. 1, a long plate body for insertion 1 made of a synthetic resin material is one of the parts to be inserted into a common insertion hole 15 (see FIG. 3 (a)) opened through a plurality of workpieces to be described later at the time of temporary fixing. The main part has a thickness of about 1.3 mm and is sufficiently flexible, and has a width of about several mm and a diameter φ ₁ of the common insertion hole 15 (see FIG. 3B). A required amount is formed with a narrow width, and a plurality of locking projections 2 are formed on one side surface at an appropriate pitch along the longitudinal direction. The insertion long plate 1 is integrally formed with the main body at the insertion tip portion with a width W having a required width W larger than the diameter φ ₁ of the common insertion hole 15.

  The long plate body 1 for insertion has a main portion of an appropriate length in advance and is appropriately cut each time depending on a plurality of workpieces to be temporarily fixed, or a plurality of types having different lengths are prepared in advance. Thus, it is possible to freely cope with a change in the total thickness (grip length L in FIG. 4 to be described later) of a plurality of stacked workpieces.

  The fitting member 4 is a part that is fitted to the extra insertion length portion of the long plate body 1 for insertion, is formed with a height dimension of about 5 mm, and is substantially at the center in plan view (state of FIG. 1). A locking hole 5 through which the insertion extra length is inserted is formed, and a locking claw 6 locked to the locking projection 2 is formed in the locking hole 5 so as to be movable. The locking claw 6 allows the extra insertion length portion to move into the engagement hole 5 in the insertion direction, and prevents the extra insertion length portion from moving in the direction opposite to the insertion direction.

  As described above, the configurations and functions of the insertion long plate body 1 and the fitting member 4 in the present embodiment are similar to the configurations and functions of the flexible band-shaped main body and the rectangular convex portion in the insulation lock. is there.

  FIG. 2 shows a positioning guide 7A in the present embodiment. The positioning guide 7A is formed at a cylindrical guide body 8 having an outer peripheral surface corresponding to the inner peripheral surface of the common insertion hole 15, and at one end (upper end in FIG. 2) of the guide main body 8. A conical peripheral hooking portion 9 as a peripheral hooking portion that is in contact with the periphery of one opening of the insertion hole 15, and the guide body portion 8 and the conical peripheral hooking portion 9 are opened through the insertion hole An insertion hole 10 through which the long plate 1 is inserted is provided.

The conical peripheral hooking portion 9 has a diameter φ _{2 that} is larger than the diameter φ ₁ of the common insertion hole 15 by a required amount, and the conical side to the periphery of one opening of the common insertion hole 15 is conical. A tapered recess 11 (see FIG. 3A) corresponding to the conical shape 9a is formed around the one opening. The total height h of the positioning guide 7A including the conical peripheral hooking portion 9 and the guide main body portion 8 is shorter than the total thickness (grip length L) of a plurality of workpieces.

  The conical peripheral latching portion 9 has a conical shape 9a on the side of the conical peripheral latching portion 9 that is in contact with the periphery of the one opening, and a tapered recess 11 on the one peripheral portion of the common insertion hole 15 correspondingly. As a result, the contact area of the conical peripheral hooking portion 9 with respect to the periphery of one opening of the common insertion hole 15 at the time of temporarily fastening a plurality of workpieces can be increased, and the plurality of workpieces can be temporarily joined more firmly. It becomes possible. Further, as will be described later, the conical peripheral hooking portion 9 can make the projection length from the workpiece at the time of temporary fastening zero, and can further reduce the projection length of the entire temporary fastener of the workpiece. It becomes.

Next, with reference to FIGS. 3A, 3 </ b> B, 3 </ b> C, and FIG. 4, the usage and operation of the workpiece temporary fastener 12 </ b> A having the above-described component structure will be described. The common insertion hole 15 opened through the plurality of workpieces 13 and 14 is opened in a state where the positional relationship between the plurality of workpieces 13 and 14 is maintained at a predetermined positional relationship. When the plurality of workpieces 13 and 14 are temporarily fixed, first, the positioning guide 7A is inserted through the insertion hole 10 so as to be movable through the insertion hole 10. Then, the guide body 8 in the positioning guide 7A faces the common insertion hole 15, and the width W is formed to be larger than the diameter φ ₁ of the common insertion hole 15 by a required amount (W> φ ₁ ). The portion of the stop portion 3 is inserted into the common insertion hole 15.

  At this time, since the latching part 3 has flexibility including the long plate body 1 for insertion, as shown in FIG.3 (b), it bends in the width direction and penetrates the common insertion hole 15. As shown in FIG. 3C, the original width W is restored at the protruding portion from the common insertion hole 15. In this state, the fitting member 4 is fitted to the extra insertion length portion of the long plate body 1 for insertion. In the example of FIG. 3A, the fitting member 4 is fitted via a washer 16 in order to increase the strength of temporary coupling. The movement of the fitting member 4 is allowed without moving the locking claw 6 to the locking projection 2 with respect to the movement of the positioning guide 7A toward the conical peripheral latching portion 9 side, and the opposite is possible. With respect to the movement in the direction, the locking claw 6 is locked to the locking projection 2 and the movement is prevented.

  For this reason, as shown in FIG. 4, the locking claw 6 in the fitting member 4 is pulled back by pulling back the end of the insertion extra length while pushing the fitting member 4 toward the conical peripheral latching portion 9. The conical peripheral hooking portion 9 is locked to the locking protrusion 2 in the long plate body 1 for insertion, and is in close contact with the tapered recess 11 around the one opening of the common insertion hole 15 and is the original. The latching portion 3 on the protruding portion side returned to the width is latched on the other peripheral edge portion 14 a of the common insertion hole 15. As a result, the plurality of workpieces 13 and 14 are temporarily coupled and temporarily fixed, and at the same time, the plurality of workpieces 13 and 14 are guided by the guide body portion 8 having an outer peripheral surface shape corresponding to the inner peripheral surface shape of the common insertion hole 15. The positional relationship between the plurality of workpieces 13 and 14 is prevented by maintaining the positional relationship therebetween.

  At the time of this temporary fixing, as shown in FIG. 4, the conical peripheral hooking portion 9 in the positioning guide 7 </ b> A is fitted into the tapered recess 11 in the vicinity of one of the openings so that the protrusion length from the workpiece 13 is increased. However, the insertion surplus length portion of the long plate for insertion 1 and the fitting member 4 fitted to the surplus insertion length portion protrude from the surface portion of the work 13. However, the height of the fitting member 4 is about 5 mm as described above, and an unnecessary portion of the insertion length portion made of a synthetic resin material can be easily cut with a nipper or the like. Therefore, the protruding length of the temporary fixing tool 12A to the surface portion of the workpiece 13 can be about 10 mm or less, and interference with a processing machine such as rivet hole drilling after temporary fixing is prevented.

  FIG. 5 shows an example in which the work temporary fastener 12A according to the present embodiment is applied to temporary connection during assembly of the wing skin 17 and the girder 18 as aircraft parts. The spar 18 is assembled to the inside of the wing outer plate 17, and the wing outer plate 17 and the spar 18 extend to an appropriate length on the back side of the paper surface of FIG.

  Regarding the temporary connection between the upper blade outer plate 17 and the girder 18 in FIG. 5, the usage of the workpiece temporary fastener 12 </ b> A will be described in the order from the left side to the right side of FIG. 5. The common insertion hole 15 is opened through the blade outer plate 17 and the girder 18 in a state where the positional relationship between the blade outer plate 17 and the girder 18 is maintained in a predetermined positional relationship. The insertion guide 7A is inserted through the insertion hole movably through the insertion long plate body 1 so that the guide main body of the positioning guide 7A faces the common insertion hole 15, and the insertion long plate body is inserted. 1 is inserted into the common insertion hole 15.

  The fitting member 4 is fitted to the insertion extra length of the long plate body 1 for insertion, and the end of the extra insertion length is pushed while pushing the fitting member 4 toward the conical peripheral latching portion of the positioning guide 7A. Pull back. By this operation, the locking claw in the fitting member 4 is locked to the locking projection of the insertion plate 1, and the conical peripheral latching portion in the positioning guide 7 </ b> A is around one opening of the common insertion hole 15. The latching portion 3 in the insertion long plate 1 is latched to the other peripheral edge of the common insertion hole 15 in close contact with the tapered recess.

  As a result, the wing outer plate 17 and the girder 18 are temporarily coupled and temporarily fixed, and at the same time, the positional relationship between the wing outer plate 17 and the girder 18 in the guide main body portion of the positioning guide 7A is a predetermined positional relationship. So that the displacement between the blade outer plate 17 and the girder 18 is prevented.

  After the temporary fixing, the unnecessary length of the insertion extra length in the long insertion plate 1 is cut with a nipper or the like, so that the projecting length of the temporary fixing tool 12A of the workpiece on the upper surface of the blade outer plate 17 is about 10 mm or less. Interference with a processing machine such as rivet hole drilling after temporary fixing is prevented. The temporary fixing of the blade outer plate 17 and the girder 18 by the temporary fixing tool 12A and prevention of displacement are performed in the same manner as described above also between the lower blade outer plate 17 and the beam 18 in FIG. .

  As described above, in the workpiece temporary fixing tool 12A according to the present embodiment, the positional relationship between the plurality of workpieces 13 and 14 is held at a predetermined positional relationship by the guide main body portion 8 in the positioning guide 7A during temporary fixing. Thus, it is possible to prevent displacement between the plurality of workpieces 13 and 14 without requiring insertion of positioning pins.

  The protruding length of the temporary fastener 12A to the surface portion of the work 13 can be set to about 10 mm or less, and interference with a processing machine such as rivet hole opening can be prevented. Therefore, the workability of the processing machine can be made extremely good.

  Since the insertion long plate body 8 including the latching portion 3 is made of a synthetic resin material, the latching portion 3 and the insertion long plate body 1 are in elastic contact with the workpieces 13 and 14. , 14 can be prevented from being damaged.

  The long plate body 1 for insertion is appropriately cut according to the grip length L of the workpieces 13 and 14 to be temporarily fixed with the main body having an appropriate length in advance, or a plurality of different lengths are prepared in advance. By doing so, it is possible to freely cope with a change in the grip length L of the plurality of stacked workpieces 13 and 14.

  The conical peripheral hooking portion 9 has a conical shape 9a on the side facing the periphery of one opening, and correspondingly, the peripheral side of the one opening is a tapered recess 11. The contact area of the conical peripheral latching portion 9 with respect to the periphery of the one opening at the time of stopping can be increased, whereby the plurality of workpieces 13 and 14 can be temporarily joined more firmly. Misalignment can be more reliably prevented. Furthermore, the protrusion length of the conical peripheral latching portion 9 from the work 13 at the time of temporary fixing can be made zero, and the protrusion length of the entire temporary fixing tool 12A of the work can be further reduced.

  A second embodiment of the present invention will be described with reference to FIGS. FIG. 6 shows the positioning guide 7B in the present embodiment. The positioning guide 7B of the present embodiment has a cylindrical guide main body portion 19 having an outer peripheral surface shape corresponding to the inner peripheral surface shape of the common insertion hole 15, and one end of the guide main body portion 19 (the upper end in FIG. 6). It is formed through a hook-like peripheral hooking portion 20 as a peripheral hooking portion formed and brought into contact with the periphery of one opening of the common insertion hole 15, and through the guide main body portion 19 and the hook-like peripheral hooking portion 20. And an insertion hole 10 through which the long plate for insertion 1 is inserted.

Thus, the positioning guide 7B of the present embodiment is configured by the hook-shaped peripheral hooking portion 20 in which the peripheral hooking portion is formed in a hook shape. The diameter φ ₃ of the flange-shaped peripheral latching portion 20 is formed to be approximately the same diameter as the diameter φ ₂ of the conical peripheral latching portion 9 in the first embodiment. In the first embodiment, the total height h of the positioning guide 7A including the conical peripheral latching portion 9 and the guide main body portion 8 is shorter than the total thickness (grip length L) of a plurality of workpieces. Although formed, in this embodiment, the height of only the guide main body 19 is substantially the same as the total height h in the first embodiment.

  FIG. 7 shows a state in which a plurality of workpieces 13 and 14 are temporarily fixed using the positioning guide 7B of the present embodiment. In the present embodiment, the ridge portion of the ridge-shaped peripheral latching portion 20 is in close contact with the periphery of one opening of the common insertion hole 15. Therefore, the contact area is increased as compared with the case where the fitting member 4 directly contacts the periphery of one of the openings, and a plurality of workpieces 13 and 14 can be firmly temporarily joined. The positional deviation between the workpieces 13 and 14 can be reliably prevented.

  The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
