<Configuration of assembly jig>
The configuration of the assembly jig 1 according to one embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view showing an example of the configuration of an assembly jig 1 according to one embodiment. FIG. 2 is a view of the base portion 10 as viewed from above. FIG. 3 is a view of the base portion 10 shown in FIG. 2 as viewed from the A direction indicated by an arrow.

  The assembly jig 1 supports parts to be assembled (hereinafter referred to as assembly parts). For example, the assembly jig 1 is used for fixing other parts to the assembly part by welding or the like while supporting the assembly part of the vehicle (for example, the frame of the side door). The assembly part may be a prototype part or a mass production part. As shown in FIG. 1, the assembly jig 1 includes a base portion 10 and a plurality of support portions 20A to 20K.

  The base portion 10 is a portion that becomes a base of the assembly jig 1. A plurality of support portions 20 </ b> A to 20 </ b> K are fixed to the base portion 10. The base portion 10 is formed by combining a plurality of metal plates. Specifically, the base portion 10 has a structure in which an upper plate 11 and lower plates 12 and 13 are combined.

  As shown in FIG. 2, the upper plate 11 is a rectangular flat plate. The upper plate 11 is provided with through holes 11a to 11k for fixing the support portions 20A to 20K with fastening members. For example, the support portion 20A is fixed to the upper plate 11 by a fastening member in which the screw portion passes through the through hole 11a.

  A plurality of lower plates 12 and 13 are provided at predetermined intervals below the upper plate 11 to support the upper plate 11. As shown in FIG. 3, the lower plates 12 and 13 are fixed to the upper plate 11 with fastening members 15 including bolts and nuts. The lower plate 12 is provided so as to be orthogonal to the lower plate 13. Thereby, the rigidity of the base part 10 can be improved.

  The upper plate 11 and the lower plates 12 and 13 have the same thickness, for example, 6 (mm). In such a case, even if the thickness of the upper plate 11 and the lower plates 12 and 13 is small, the structure of the upper plate 11 and the lower plates 12 and 13 is combined to increase the rigidity of the base portion 10. Is possible.

  The upper plate 11 and the lower plates 12 and 13 are cut plates cut by laser processing, as will be described in detail later. In the case of laser processing, since the accuracy of the processing itself is high, the upper plate 11 and the lower plates 12 and 13 can be processed in a shorter processing time than in the case of machining that requires a plurality of steps to ensure accuracy. Can be molded.

  The support parts 20A to 20K are fixed in a state where they are scattered on the base part 10, and support the assembly parts. In a state where the support parts 20A to 20K support the assembly parts, other parts are fixed to the assembly parts by welding or the like. Each of the support portions 20A to 20K has a structure in which a plurality of metal plates having the same thickness overlap each other. Although the details will be described later, the plurality of metal plates are cut plates cut by laser processing.

Here, a detailed configuration of the support portion 20E will be described with reference to FIGS.
FIG. 4 is a perspective view showing the support portion 20E. FIG. 5 is a front view of the support portion 20E. As shown in FIG. 5, the support part 20 </ b> E includes a support part 100, a holding part 110, a connection part 120, a fitting part 130, a step part 140, marking parts 151 and 152, and a notch part 160. Have

  The support part 100 is fixed to the base part 10 with a fastening member 170 and supports the assembly component. As shown in FIG. 4, the support portion 100 has a structure in which three cutting plates 101, 102, and 103 are stacked. The thicknesses of the three cutting plates 101 to 103 are the same, and the appearance shapes are substantially the same. The thicknesses of the cutting plates 101 to 103 are the same as the thicknesses of the upper plate 11 and the lower plates 12 and 13 of the base part 10.

  The cut plates 101 to 103 in an overlapped state are fixed by a fastening member 105. Here, the fastening member 105 includes a bolt and a nut. The cutting plates 101 to 103 are formed with through holes through which the screw portions of the fastening member 105 pass. Here, the diameter of the through hole is the same as the thickness of each of the cutting plates 101 to 103. In the case of cutting by laser processing, the diameter of the through hole needs to be equal to or greater than the thickness of the cutting plate due to the characteristics of laser processing. On the other hand, when the support part 100 is configured by stacking three cutting plates 101 to 103, the diameter of the through hole is larger than that when the support part 100 is configured by a single cutting plate having a large thickness. Easy to make small.

  The pressing part 110 faces the support part 100 and presses the assembly component supported by the support part 100. That is, the holding part 110 has a function of a grip part that grips an assembly component in cooperation with the support part 100. The holding part 110 has a structure in which three cutting plates 111, 112, and 113 are stacked in the same manner as the support part 100. The thicknesses of the three cutting plates 111 to 113 are the same, and the external shapes are substantially the same. Moreover, the thickness of the cutting plates 111-113 is the same magnitude | size as the thickness of the cutting plates 101-103.

  The cut plates 111 to 113 in an overlapped state are fixed by fastening members 115 including bolts and nuts. The cutting plates 111 to 113 are formed with through holes through which the screw portions of the fastening member 115 pass, and the diameters of the through holes are the same as the thicknesses of the cutting plates 111 to 113.

  In the above description, the support part 100 and the pressing part 110 have a structure in which three cutting plates 101 to 103 and 111 to 113 are stacked, but the present invention is not limited thereto. For example, the support unit 100 and the holding unit 110 may have a structure in which two cutting plates are stacked, or may have a structure in which four or more cutting plates are stacked.

  The connecting part 120 connects the support part 100 and the pressing part 110. Specifically, the connecting part 120 connects the supporting part 100 and the pressing part 110 so that the pressing part 110 can rotate with respect to the supporting part 100 fixed to the base part 10. As shown in FIG. 4, the connecting portion 120 includes a pair of flat plates having the same thickness as the cutting plates 101 to 103, and a fastening member that fixes the flat plate, the support portion 100, and the pressing portion 110.

  As shown in FIG. 5, the fitting portion 130 is a portion where the pressing portion 110 and the support portion 100 are fitted when the pressing portion 110 is located at the closed position. Thereby, the pressing part 110 is positioned at a desired position with respect to the support part 100.

  6 is a cross-sectional view taken along line BB in FIG. As shown in FIG. 6, the fitting portion 130 includes a fitting convex portion 131 and a fitting concave portion 132 that can be fitted to the fitting convex portion 131. The fitting convex portion 131 is formed on the upper end of the central cutting plate 102 among the cutting plates 101 to 103 of the support portion 100. The fitting recess 132 is formed at the lower end of the cutting plate 112 among the cutting plates 111 to 113 of the pressing portion 110. In the case of such a configuration, it is not necessary to separately provide a positioning member for positioning the pressing portion 110 on the support portion 100, so that the number of parts can be reduced.

  In the above description, the fitting convex portion 131 is formed on the cutting plate 102 of the support portion 100 and the fitting concave portion 132 is formed on the cutting plate 112 of the holding portion 110. However, the present invention is not limited to this. For example, the fitting convex portion 131 may be formed on the cutting plate 101 and the fitting concave portion 132 may be formed on the cutting plate 111. Further, the fitting convex portion 131 may be formed on the cutting plate 112 of the holding portion 110 and the fitting concave portion 132 may be formed on the cutting plate 102 of the support portion 100.

  Returning to FIG. 4, the stepped portion 140 is a portion that supports the assembly component obliquely. Specifically, the stepped portion 140 supports an inclined portion that is inclined obliquely in the assembly component. The step portion 140 is formed by changing the positions of the upper end surfaces of the cutting plates 101 to 103 of the support portion 100 and changing the positions of the lower end surfaces of the cutting plates 111 to 113 of the pressing portion 110.

  FIG. 7 is a schematic diagram for explaining an example of the configuration of the stepped portion 140 of the support portion 20E. As shown in FIG. 7, in the support portion 100, the upper end surfaces 101a, 102a, 103a of the cutting plates 101, 102, 103 support the inclined portion P of the assembly part. The upper end surfaces 101a to 103a are horizontal surfaces and are positioned so that the height gradually decreases. A part of the upper end surfaces 101 a to 103 a having different heights is in contact with the inclined portion P. In the holding part 110, the lower end surfaces 111 a, 112 a, 113 a of the cutting plates 111, 112, 113 hold down the inclined part P. The lower end surfaces 111a to 113a are also horizontal surfaces, and part of the lower end surfaces 111a to 113a having different heights are in contact with the inclined portion P. When the above-described horizontal upper end surfaces 101a to 103a and lower end surfaces 111a to 113a are provided as the stepped portions 140, it is not necessary to cut the end surfaces obliquely, so that the processing time for forming the stepped portions 140 can be reduced. .

  Returning to FIG. 4, the marking portion 151 is a mark portion that specifies the order in which the three cutting plates 101 to 103 of the support portion 100 are stacked. Here, as the marking portion 151, the cut plates 101 to 103 are provided with semicircular cutouts having different sizes. Actually, the cut plates 101 and 102 are provided with semicircular cutouts having different sizes, and the cut plate 103 is not provided with a semicircular cutout. Similarly, the marking portion 152 is a portion that specifies the order in which the three cutting plates 111 to 113 of the pressing portion 110 are stacked. Specifically, the cut plates 111 and 112 are provided with semicircular cutouts having different sizes, and the cut plate 113 is not provided with a semicircular cutout. In such a case, when the cutting plates are stacked, the operator can prevent the cutting plates 101 to 103 and 111 to 113 from being erroneously stacked by looking at the marking portions 151 and 152.

  The notch 160 is provided in the lower part of the support part 100. The notch portion 160 is formed by notching the lower portion of the support portion 100. The notch portion 160 is a portion into which a bolt and a nut of a fastening member 170 that fixes the support portion 100 to the base portion 10 are inserted and screwed together.

  FIG. 8 is a schematic diagram for explaining a method of fixing the support portion 100 and the base portion 10 by the fastening member 170. As shown in FIG. 8A, the notch 160 has a first hole 161 and a second hole 162. The first hole 161 is formed in a rectangular shape and is a portion into which the nut 171 of the fastening member 170 is inserted. The second hole 162 is formed in a rectangular shape so as to be orthogonal to the first hole 161, and is a portion into which a bolt 172 to be screwed with the nut 171 is inserted.

  When fixing the support part 100 to the base part 10, the operator first inserts a nut 171 into the first hole 161 of the notch 160 of the support part 100 as shown in FIG. . Next, as shown in FIG. 8 (c), the operator places the first through the through hole 11 e of the base portion 10 located below the notch portion 160 with the nut 171 inserted into the first hole portion 161. The screw portion of the bolt 172 is inserted toward the two-hole portion 162. Next, the operator screws bolts 172 and nuts 171 as shown in FIG. Thereby, the support part 100 is fixed to the base part 10 without welding.

  Although the support part 20E mentioned above is being fixed to the base part 10 with the fastening member 170, you may be fixed to the base part 10 via the scale 180 like the support part 20B shown in FIG. By using the scale 180, the support portion 20B can be easily fixed perpendicularly to the upper surface of the base portion 10.

  FIG. 9 is a perspective view showing the support 20B and the scale 180. FIG. The support portion 20 </ b> B is fixed to the scale 180 with a fastening member 170. Further, the scale 180 is fixed to the base portion 10 with a fastening member 170. The lower portion of the support portion 20B is fixed to the base portion 10 by a fastening member 170. Thereby, the support part 20B can be fixed to the base part 10 with high accuracy by a simple operation.

  In addition, support part 20A, 20C, 20D, 20F-20K which has not demonstrated detailed structure also has the structure similar to support part 20B, 20E.

(Effects of assembly jig according to this embodiment)
The assembly jig 1 described above includes a base portion 10 formed by combining an upper plate 11 and lower plates 12 and 13 which are a plurality of cutting plates, and a cutting plate having the same thickness as the cutting plate of the base portion 10 (for example, In addition, a plurality of cutting plates 101 to 103 and 111 to 113) are provided in a state where a plurality of the cutting plates 101 to 103 and 111 to 113) are overlapped, and support portions 20A to 20K fixed to the base portion 10.
In this case, since the base part 10 and the support parts 20A to 20K can be formed from the same metal plate, the metal plate can be easily cut and the manufacturing time of the assembly jig 1 can be shortened. Moreover, even if the thickness of a cutting plate is small, since the base part 10 and support part 20A-20K are formed combining the some cutting board, the rigidity of the base part 10 and support part 20A-20K can be improved.

<Manufacturing process of assembly jig>
With reference to FIG. 10, an example of the manufacturing process of the assembly jig 1 having the above-described configuration will be described. FIG. 10 is a flowchart showing an example of the manufacturing process of the assembly jig 1.

  First, the metal plate for the base portion 10 of the assembly jig 1 is cut by laser processing (step S102). Specifically, a metal plate is cut with a laser processing machine, and a cut plate (hereinafter also referred to as a first cut plate) corresponding to the upper plate 11 and the lower plates 12 and 13 of the base portion 10 is formed. The plurality of first cutting plates are cut from a metal plate having the same thickness.

  Next, the metal plate for the support portions 20A to 20K of the assembly jig 1 is cut by laser processing (step S104). The metal plates for the support portions 20A to 20K are the same type as the metal plate for the base portion 10.

  Here, as an example, the cutting of the metal plate for the support portion 20E will be described. A cutting plate corresponding to the cutting plates 101 to 103 and the cutting plates 111 to 113 having the same external shape of the support portion 20E by cutting a metal plate having the same thickness as the metal plate for the base portion 10 with a laser processing machine. (Hereinafter also referred to as a second cutting plate) is molded. In the cutting plates 101 to 103, a marking portion 151 and a notch portion 160 shown in FIG. 4 are formed, and in the cutting plates 111 to 113, a marking portion 152 is formed.

  Next, the base part 10 is shape | molded combining the some 1st cutting board cut | disconnected by step S102 (step S106). Specifically, the base portion 10 is assembled by fixing the first cutting plate corresponding to the lower plates 12 and 13 to the first cutting plate corresponding to the upper plate 11 with the fastening member 15. In such a case, it becomes easier to assemble the base portion 10 than when the lower plates 12 and 13 are fixed to the upper plate 11 by welding.

  Next, the support parts 20A to 20K are formed by combining the plurality of second cutting plates cut in step S104 (step S108). Here, the support portion 20E will be described as an example, and the second cutting plate includes the cutting plates 101 to 103 and 111 to 113. Specifically, after the cutting plates 101 to 103 are stacked in the order specified by the marking portion 151, the cutting plates 101 to 103 are fixed by the fastening member 105 to form the support portion 100. Similarly, after the cutting plates 111 to 113 are stacked in the order specified by the marking portion 152, the cutting plates 111 to 113 are fixed by the fastening member 115 to form the pressing portion 110. And the support part 100 and the holding | suppressing part 110 are connected by the connection part 120. FIG.

  Next, the support portions 20A to 20K are fixed to the base portion 10 (step S110). In the present embodiment, each of the support portions 20 </ b> A to 20 </ b> K is fixed to the base portion 10 with the fastening member 170 without performing welding. Specifically, as shown in FIG. 8, the nuts 171 and the bolts 172 are screwed together at the cutout portions 160 to fix the support portions 20 </ b> A to 20 </ b> K to the base portion 10. As described above, when the support portions 20A to 20K are fixed to the base portion 10 with the fastening member 170, the work time required for the fixing work can be shortened compared with the case where the support portions 20A to 20K are fixed by welding, and the occurrence of thermal deformation due to welding is reduced. Can be prevented.

  In addition, the manufacturing process of the assembly jig 1 is not limited to the order shown in FIG. For example, the order of the process of step S102 and the process of step S104 may be switched. Similarly, the order of the step S106 and the step S108 may be switched. Further, the step S102 and the step S104 may be performed simultaneously. That is, the first cutting plate and the second cutting plate may be cut from the same metal plate.

(Effects of the assembly jig manufacturing method according to the present embodiment)
According to the manufacturing method of the assembly jig 1 described above, a metal plate is cut into a cut plate by laser processing, and the base portion 10 and the support portions 20A to 20K are formed by combining the cut plates, and the support portion is mounted on the base portion 10. The assembly jig 1 is manufactured by fixing 20A to 20K.
Since laser processing generally has high processing accuracy, no additional processing is required for the cut portion. In the case of laser processing, even if the shape of the cutting plate is complicated, it can be easily formed. For this reason, compared with the case where a metal plate is machined, such as cutting, grinding, and polishing, the base 10 and the support portions 20A to 20K can be formed with high accuracy in a short time. In particular, when the assembly jig 1 is manufactured by cutting a metal plate by laser processing as in this embodiment, the manufacturing time is about half that of the case of manufacturing by cutting or the like by machining.
In laser processing, if the thickness of the metal plate to be cut is large, the cutting may be oblique. By cutting a metal plate having a small thickness as in this embodiment, the cutting is oblique. Can be suppressed. Furthermore, by assembling the base portion 10 by combining a plurality of cutting plates, the base portion 10 having high rigidity can be formed even if the thickness of the cutting plate is small. Similarly, the rigidity of the support portions 20A to 20K can be increased by assembling the support portions 20A to 20K by stacking a plurality of cutting plates.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
