Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coupling mechanism for plate materials, etc.
A notch is provided across the side edge of the second member and the side edge of the second member, a plastically deformable connecting member is fitted into the hole defined by the notch, and the connecting member is moved by an external force. The present invention relates to a coupling mechanism for plate materials and the like that allows the first member and the second member to be coupled by plastic deformation.

If it is necessary to change the material of the plate depending on the part, or if two parts cannot be manufactured integrally due to their shape, it is necessary to manufacture each part individually and mechanically connect the two. arise.

For example, when a part of a plate material is desired to be made of a highly hard material, the part may be hardened after processing the plate material. However, when a part of the plate material is hardened in this manner, the plate material is partially heated by the hardening, and the heat deforms the plate material, making it impossible to maintain the precise shape of the plate material.

Therefore, when manufacturing plates with partially different materials like this, the usual method is to separately manufacture plates that are hardened and unhardened after processing, and then mechanically join them together. It has been adopted. This joining technique includes, for example, when joining plate materials, a method of applying an impact to one plate material and press-fitting the other plate material. However, with this press-fitting method, there is a risk that at least one of the plate materials will undergo plastic deformation, or damage such as cracks will occur in the plate material due to impact, and in some cases, the plate material will be destroyed.

Other conventional techniques for joining two plates include overlapping the side edges of the plates or joining the sides of the plates, and abutting the plate for connection on the joint, using bolts, nuts, rivets, etc. There is a way to combine these. However, with this method, there is a concern that the nut may loosen or fall off due to vibration of the plate material.

Further, since rivets connect plate materials by deforming their heads, there is a possibility that at least one of the plate materials may be deformed when driving the rivet. Furthermore, since these bolts, nuts, rivets, etc. protrude above the surface of the plate material, they become an obstacle when other equipment is placed nearby, and they also have the disadvantage of being poor in appearance.

On the other hand, there is also a method of joining the sides of the plate materials and fixing the joint by welding, but in this case, it is necessary to polish and remove the raised part of the solvent that has formed on the surface of the plate materials due to the welding method. In addition, the heat generated during welding causes deformation or deterioration of the bonded parts of the plates.

The present invention has been made in order to overcome the above-mentioned disadvantages, and is defined by forming a notch at the joint of the first member and the second member and joining these notches. Place the connecting member in the hole.

This makes it possible to firmly connect two members without damaging or deforming them by fitting them together and plastically deforming this joining member by external force, and also eliminates the need for work such as polishing the joint part of the members after joining. The purpose is to provide a mechanism for joining plate materials, etc.

In order to achieve the above object, the present invention provides a coupling mechanism for coupling a first member and a second member, in which cutouts are formed at the joint portions of the first and second members, and these cutouts are provided. By joining the parts, a hole having two wide and narrow openings, a first opening and a second opening that communicate with each other, is defined, and a first opening wider than the first opening is defined between the two openings. 1
grooves are defined in each of the two members, while a second groove is defined between the flange and the main body of the member having a flange and fitted into the hole, and a second groove is defined in the first member. A plastically deformable coupling member is sandwiched between the groove and the second groove, the member is press-fitted into the hole, and the coupling member is plastically deformed in the first groove and the second groove to form the second groove. It is characterized in that the first member and the second member are connected.

Next, preferred embodiments of the coupling mechanism for plates and the like according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 indicates a coupling mechanism for plates and the like according to the present invention. This plate joining mechanism 10 is applied, for example, to join a metal plate 12 as a first plate material that is hardened after processing and a metal plate 14 as a second plate material that is not hardened after processing. . Semicircular notches 18a to 18c forming the plate joining mechanism 10 are formed in side surfaces 16a to 16C of the metal plate 12 that are joined to the metal plate 14, respectively. On the other hand, side surfaces 20a to 2Qc of the metal plate 14 corresponding to these notches 18a to 18c also have semicircular notches 22a to 22c constituting the plate coupling mechanism 10.

Incidentally, ring-shaped grooves 46a to 46e whose diameters are selected to be smaller than those of the flanges 44a to 44c are carved at the boundary portions between the flanges 42a to 42c and the flanges 44a to 44c. In this case, the flanges 44 of the pins 38a to 38c
A to 44C are connecting members 40a to 40 made of ring-shaped fl wires or the like that are softer than the metal plate 12.14 and the pins 38a to 38c and easily deform plastically in response to external force.
This is for inserting the c.

The coupling mechanism for plates and the like according to the present invention is basically constructed as described above, and its operation and effects will be explained next.

First, each side surface 16a to 16C of the metal plate 12 is made of metal v.
The metal plate 12 is fitted to the metal plate 14 so as to be joined to the side surfaces 20a to 20c of the metal plates 14 and 14, respectively. At this time, the notches 18a to 18c formed in the metal plate 12 are
The holes 24a face the notches 22a to 22c of No. 4, respectively.
24C to 24C are configured. The state at this time is shown in FIG.

Therefore, the coupling member 4 is inserted into the second flanges 44a to 44C of the pins 38a to 38c into these holes 24a to 24c.
They are fitted with 0a to 40C interposed therebetween. pin 38a
38C are large diameter portions 2 defining holes 24a to 24c.
They are inserted from the 6a to 26c and 28a to 28C sides. At this time, the second flange 44 of the pins 38a to 38c
a to 44C are fitted into the small diameter portions of the holes 24a to 24c, while the first flanges 42a to 42c are fitted to the small diameter portions of the holes 24a to 24c.
This results in fitting into the large diameter portions of 24c to 24c. Therefore, the coupling member 40a that fits into the second flanges 44a to 44c
The pins 38a to 40c are sandwiched between the flanges 42a to 42c of the pins 38a to 38c and the small diameter portion of the metal plate 12.14. The state at this time is shown in FIG.

Next, the metal plate 12.14 is placed on a support stand 48 having a smooth surface.
The end faces of the pins 38a to 38c on the flanges 42a to 42c side are pressed in the direction of the arrow in FIG. 3. At this time, flanges 42a to 42C of pins 38a to 38c
The coupling members 40a to 40c sandwiched between the small diameter portion of the metal plate 12.14 are pressed and plastically deformed. A portion of the plastically deformed coupling members 40a to 40c is attached to the pin 3.
The grooves 46a to 46c of the pins 38a to 38c are press-fitted, and a part of the pins are sandwiched between the flanges 42a to 42C of the pins 38a to 38c and the small diameter part of the metal plate 12.14, and the remaining part is inserted into the metal plate 12.14. 12.14 Shando 34a to 34
C and 36a to 36c, resulting in the state shown in FIG.

As a result, the grooves 46a to 46C of the pins 38a to 38c
and the grooves 34a to 34c of the metal plate 12, the grooves 46a to 46C of the pins 38a to 38c, and the groove 36a of the metal plate 14.
36c are connected by the plastically deformed coupling members 40a to 40c, respectively, and pins 38a to 38C are fixed in the holes 24a to 24c. Therefore, the metal plate 12 is prevented from moving in a direction perpendicular to the plane of the metal plate 14 by the coupling members 40a to 40c, and the metal plate 12 is prevented from moving in a direction along the plane of the metal plate 14 by the pins 38a to 38c. movement is prevented.

In this way, metal plates 12 and 14 are joined.

As described above, according to the present invention, a notch is formed at the joining portion of two plates so as to face each other, and a member having a flange in the hole defined by the notch is plastically deformed. These two plates are deformed or damaged by fitting them together via a coupling member, plastically deforming this coupling member by external force, and press-fitting the coupling members into respective guides carved in the plate material in the hole. Furthermore, unlike when bolts are used, the connecting member fitted between the plates does not protrude above the surface of the plates, allowing thin plates to be joined together beautifully. Furthermore, since these plates are not joined by welding, there is no deformation due to the heat generated during welding, and when using the welding method, work such as polishing the joint of the plates after welding is easy. In addition, since the coupling mechanism is simple, there is no need for any special equipment, and there are also practical advantages such as no need for skilled techniques.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments, and can be applied not only to plate materials but also to any material used when engaging two members. Of course, various improvements and changes in design are possible without departing from the gist of the present invention.
