[0005] Patent Document 1: Japanese Patent Application Publication No. 2008-73835 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, when assembling components to objects using bolts, sometimes the object cannot be directly viewed or the hands cannot be used, making it difficult to ensure a good working environment. In such cases, it is difficult to assemble components to objects using bolts.

[0008] The purpose of this invention is to provide a technique that allows assembly components to be easily assembled onto an object component using multiple bolts, regardless of the working environment.

[0009] Methods for solving problems

[0010] According to a first aspect of this invention, a component assembly fixture is provided for assembling assembly components to object components using multiple bolts. The component assembly fixture includes: a fixture body for temporarily holding the assembly components; and at least one positioning guide for positioning multiple bolt through holes of the assembly components to multiple threaded holes of the object component. Based on this structure, the multiple bolt through holes can be positioned to the multiple threaded holes using the at least one positioning guide, thus allowing the assembly components to be easily assembled to the object component using the multiple bolts regardless of the working environment.

[0011] Preferably, the fixture body has multiple tool insertion holes corresponding to the multiple bolt through holes. Based on this structure, the assembly element can be directly assembled to the object element using the multiple bolts while the fixture body temporarily holds the assembly element.

[0012] Preferably, the clamp body has a tool guide groove that extends in such a way that two of the openings of the plurality of tool insertion holes are connected. With this structure, the tool can be easily moved from one of the two openings of the plurality of tool insertion holes to the other.

[0013] Preferably, the clamp body has a tool guide groove that extends annularly in a manner connecting the openings of the plurality of tool insertion holes to each other. According to the above structure, tools can be easily moved between the openings of the plurality of tool insertion holes.

[0014] Preferably, the tool guide groove is formed continuously. Based on the above structure, the direction of tool movement when the tool is moved between the openings of the plurality of tool insertion holes is not limited.

[0015] Preferably, while the jig body temporarily holds the assembly element, a plurality of head receiving spaces are formed between the assembly element and the jig body. These multiple head receiving spaces respectively receive the heads of a plurality of bolts inserted into the plurality of bolt through holes of the assembly element. The jig body has a jig-side bolt-facing surface, which restricts the movement of the head in the bolt insertion direction by being opposite to the head of each bolt received in each head receiving space in the bolt insertion direction. The assembly element has an element-side bolt-facing surface, which restricts the movement of the head in the bolt insertion direction by being opposite to the head of each bolt received in each head receiving space in the bolt insertion direction. The distance between each jig-side bolt-facing surface and its corresponding element-side bolt-facing surface is larger than the dimension of the corresponding head in the bolt insertion direction. According to the above structure, the assembly element can be temporarily held in the jig body while the plurality of bolts are pre-inserted into the plurality of bolt through holes of the assembly element.

[0016] Preferably, the at least one positioning guide includes a plurality of positioning guides, each positioning guide having a guide surface capable of contacting the outer peripheral surface of the cylindrical portion of the object element having a corresponding threaded hole.

[0017] According to a second aspect of this invention, a component assembly method is provided, which uses multiple bolts to assemble an assembly component onto a target component. The component assembly method includes the following steps: temporarily holding the assembly component in the fixture body of a component assembly fixture, the component assembly fixture including: the fixture body for temporarily holding the assembly component; and at least one positioning guide for positioning multiple bolt through holes of the assembly component into multiple threaded holes of the target component, and using the at least one positioning guide to position the multiple bolt through holes of the assembly component into the multiple threaded holes of the target component. According to the above method, the at least one positioning guide can be used to position the multiple bolt through holes into the multiple threaded holes, therefore, regardless of the working environment, the assembly component can be easily assembled onto the target component using the multiple bolts.

[0018] Preferably, the method further includes the step of temporarily holding the assembly element in the fixture body after inserting the plurality of bolts into the plurality of bolt through holes of the assembly element. According to the above method, the plurality of bolts can be inserted into the plurality of bolt through holes of the assembly element before the plurality of bolt through holes of the assembly element are positioned in relation to the plurality of threaded holes of the object element using the at least one positioning guide.

[0019] Preferably, the method further includes the following step: directly fastening the plurality of bolts to the plurality of threaded holes of the object element while the assembly element is temporarily held in the fixture body.

[0033] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 The diagram shows the state in which assembly element 2 is assembled onto object element 1 using multiple bolts 3. Figure 2 Only object element 1 is shown in the image. Figure 3 A perspective view of assembly component 2 is shown in the figure.

[0034] like Figure 3 As shown, assembly element 2 is typically an electronic device. Assembly element 2 includes a generally flat assembly element body 4 and three fixing protrusions 5 protruding outward from the assembly element body 4. The assembly element body 4 is constructed by housing an electronic substrate within a metal casing, such as hard aluminum. The three fixing protrusions 5 are integrally formed with the casing of the assembly element body 4. Each fixing protrusion 5 has an upper surface 5a and a lower surface 5b. The upper surface 5a is a tapered surface. A bolt through hole 6 is formed in each fixing protrusion 5. Each bolt through hole 6 is formed to open on the corresponding upper surface 5a and lower surface 5b of the fixing protrusion 5. A component-side head receiving recess 5c is formed on the upper surface 5a. Each fixing protrusion 5 has a component-side bolt facing surface 5d that divides the component-side head receiving recess 5c in the vertical direction. The three bolt through holes 6 are formed parallel to each other with their central axes. The three bolt through holes 6 extend parallel to the thickness direction of the assembly element body 4.

[0035] Reference Figure 2 The object element 1 includes a thin plate-shaped object element body 20, a storage box 21 disposed on the object element body 20 and housing the assembly element 2, and three cylindrical assembly bases 22.

[0036] Three assembly bases 22 are disposed within the internal space of the storage box 21. The three assembly bases 22 are formed to protrude from the object component body 20. The three assembly bases 22 protrude parallel to the thickness direction of the object component body 20. Hereinafter, the direction in which each assembly base 22 protrudes from the object component body 20 is defined as "upper," and its opposite direction as "lower." "Up-down direction" is defined as a direction that includes both "upper" and "lower." Therefore, the three assembly bases 22 are formed to protrude upward from the upper surface 20a of the object component body 20. A threaded hole 23 is formed on the upper surface 22a of each assembly base 22.

[0037] The storage box 21 includes a top plate 21a and four side plates 21b. The top plate 21a is vertically opposite to the upper surface 20a of the object component body 20. Maintenance holes 24 are formed in the top plate 21a. The maintenance holes 24 are channels for assembling the assembly component 2 onto the three assembly bases 22 disposed inside the storage box 21. Figure 1 As shown, the maintenance hole 24 is not formed directly above the assembly element 2 assembled on the object element 1, and the maintenance hole 24 is not formed to be as large as two hands can be inserted at the same time.

[0038] Therefore, when using multiple bolts 3 to assemble the assembly component 2 to the object component 1, it is not only impossible to directly see the object component 1, but also the internal space of the storage box 21 is dark, and the working environment is harsh, making it difficult to use multiple bolts 3 to assemble the assembly component 2 to the object component 1.

[0039] Therefore, in this embodiment, the following is used Figures 4-6 The component assembly fixture 30 shown assembles the assembly component 2 onto the object component 1. Figure 4 as well as Figure 5 A perspective view of the component assembly fixture 30 is shown. Figure 6 A top view of the component assembly fixture 30 is shown.

[0040] It should be noted that the relative posture of the component assembly fixture 30 to the object component 1 when assembling the assembly component 2 onto the object component 1 is unique. Therefore, in the following description of the component assembly fixture 30, the posture of the fixture relative to the object component 1 will be used directly. Figure 2 The terms "above", "below", and "vertical direction" are defined based on the composition of object element 1.

[0041] However, terms such as "above," "below," and "up and down direction" are used for ease of explanation and are not interpreted as limiting the actual posture of object component 1, assembly component 2, and component assembly fixture 30 during use.

[0042] Reference Figure 4 as well as Figure 5The component assembly fixture 30 is made of, for example, insulating resin and includes a fixture body 31 that temporarily holds the assembled component 2 and three positioning guides 32 that position the plurality of bolt through holes 6 of the assembled component 2 into the plurality of threaded holes 23 of the target component 1.

[0043] The clamp body 31 includes a ring portion 33 that extends continuously in a ring shape, three legs 34 that protrude downward from the ring portion 33, a protective plate 35, and two elastic retaining plates 36.

[0044] The ring portion 33 extends in a rectangular shape. The ring portion 33 has an upper surface 33a and a lower surface 33b. A tool guide groove 37 is formed on the upper surface 33a. The tool guide groove 37 is formed continuously in a ring shape along the ring portion 33. The tool guide groove 37 has a groove bottom surface 37a.

[0045] Each leg 34 protrudes downward from the lower surface 33b of the ring 33. Here, we would like to refer to... Figure 7 .exist Figure 7 The image, in cross-section, depicts the assembly of component 2 onto object component 1 using component assembly fixture 30. For example... Figure 7 As shown, each leg 34 has a tapered surface 34a that faces the upper surface 5a of the corresponding fixing protrusion 5 of the assembly element 2 when the clamp body 31 temporarily holds the assembly element 2, and a reference surface 34b that makes surface contact with the upper surface 22a of the assembly base 22 when the assembly element 2 is assembled to the object element 1. A clamp-side head receiving recess 34c is formed on the tapered surface 34a. Each leg 34 has a clamp-side bolt facing surface 34d that divides the clamp-side head receiving recess 34c in the vertical direction. When the clamp body 31 temporarily holds the assembly element 2, the component-side head receiving recess 5c of each fixing protrusion 5 and the clamp-side head receiving recess 34c of each leg 34 constitute a head receiving space E for receiving the head 3a of the corresponding bolt 3. The vertical dimension of the head storage space E, i.e., the vertical distance Ed between the clamp-side bolt-facing surface 34d and the component-side bolt-facing surface 5d, is larger than the vertical dimension 3d of the bolt head 3a. Therefore, with the bolt head 3a stored in the head storage space E, the bolt 3 can move within a predetermined range in the vertical direction relative to the object component 1, the assembly component 2, and the component assembly fixture 30. In this embodiment, the head 3a of each bolt 3 is a head with a hexagonal hole, but it is not limited to this.

[0046] Continue as Figure 7As shown, each leg 34 has a tool insertion hole 38. Each tool insertion hole 38 is formed vertically, opening onto the clamp-side bolt-facing surface 34d of the clamp-side head receiving recess 34c of each leg 34 and onto the upper surface 33a of the ring 33. In other words, each tool insertion hole 38 opens onto the clamp-side bolt-facing surface 34d of the clamp-side head receiving recess 34c of each leg 34 and onto the bottom surface 37a of the tool guide groove 37 formed on the upper surface 33a of the ring 33. Furthermore, as... Figure 6 As shown, the annular tool guide groove 37 extends continuously in a ring shape, connecting the openings 38a of the three tool insertion holes 38 to each other. Therefore, as Figure 7 As shown, after inserting a hex wrench R into a tool insertion hole 38 and tightening the corresponding bolt 3 into the threaded hole 23 of the assembly base 22, the hex wrench R is pulled out of the tool insertion hole 38, allowing the tip Ra of the hex wrench R to slide on the bottom surface 37a of the tool guide groove 37. This allows the tip Ra of the hex wrench R to be moved to other tool insertion holes 38 without visual inspection. It should be noted that the hex wrench R is a specific example of a tool.

[0047] Continue as Figure 7 As shown, each positioning guide 32 is formed to protrude downward from the reference surface 34b of the corresponding leg 34. Each positioning guide 32 has a curved guide surface 40 that can contact the outer peripheral surface 22b of the corresponding assembly base 22 and a tapered surface 41 for guiding the corresponding assembly base 22 toward the guide surface 40. By aligning the guide surface 40 of each positioning guide 32 with the outer peripheral surface 22b of the corresponding assembly base 22, the corresponding bolt through hole 6 is positioned in the threaded hole 23 of the corresponding assembly base 22.

[0048] return Figure 4 The protective plate 35 will, when assembling component 2 onto object component 1, Figure 3 The assembly element 2 shown is covered and difficult to touch, thereby preventing the assembly element 2 from falling off the component assembly fixture 30. The protective plate 35 can be omitted.

[0049] like Figure 4 as well as Figure 5 As shown, two elastic retaining tabs 36 protrude downward from the lower surface 33b of the ring portion 33. By inserting the assembly element 2 between the two elastic retaining tabs 36, the two elastic retaining tabs 36 of the clamp body 31 hold the assembly element 2 in a freely detachable manner. In other words, by inserting the assembly element 2 between the two elastic retaining tabs 36, the two elastic retaining tabs 36 of the clamp body 31 temporarily hold the assembly element 2.

[0050] It should be noted that the positioning of assembly component 2 and component assembly fixture 30 in a direction orthogonal to the vertical direction is achieved, for example, by... Figure 7 This is achieved through surface contact between the outer surface 5e of each fixed protrusion 5 and the inner surface 34e of each leg 34.

[0051] Next, refer to Figures 8-11 This describes a component assembly method that uses multiple bolts 3 to assemble component 2 onto object component 1. Figure 8 The diagram shows a scenario where multiple bolts 3 are installed on assembly component 2. Figure 9 The diagram shows a situation where the assembly element 2 is temporarily held in the component assembly fixture 30. Figure 10 The diagram shows a case where the assembly element 2 is directly assembled onto the object element 1 while the assembly element 2 is temporarily held in the element assembly fixture 30. Figure 11 The flowchart of the component assembly method is shown.

[0052] like Figure 11 As shown, the component assembly method includes a bolt insertion process (S100), a temporary holding process (S110), a positioning process (S120), a bolt tightening process (S130), and a fixture removal process (S140). The component assembly method includes at least a temporary holding process (S110) and a positioning process (S120).

[0053] <Bolt insertion procedure: S100>

[0054] First, such as Figure 8 As shown, bolts 3 are inserted into the bolt through holes 6 of each fixing protrusion 5 of the assembly component 2.

[0055] <Temporary holding process: S110>

[0056] Next, as Figure 9 As shown, the assembly component 2 is temporarily held in the fixture body 31 of the component assembly fixture 30. Thus, as... Figure 7 As shown, the head 3a of the bolt 3 inserted into the bolt through hole 6 of each fixing protrusion 5 of the assembly element 2 is stored in the head storage space E, so that even if the position of the assembly element 2 is reversed, the bolt 3 will not fall out of the bolt through hole 6 of each fixing protrusion 5.

[0057] <Positioning process: S120>

[0058] Next, as Figure 10 As shown, the assembly component 2 is temporarily held in the component assembly fixture 30 and directly mounted on the multiple assembly bases 22 of the target component 1. Specifically, the multiple bolt through holes 6 of the assembly component 2 are respectively positioned in the threaded holes 23 of the multiple assembly bases 22 of the target component 1.

[0059] <Bolt tightening procedure: S130>

[0060] Next, using a hex wrench R, the bolts 3, which are pre-inserted into the bolt through holes 6 of each fixing protrusion 5 of the assembly component 2, are tightened into the threaded holes 23 of the corresponding assembly base 22. Thus, the assembly component 2 is assembled to the object component 1 using multiple bolts 3.

[0061] <Clamp removal procedure: S140>

[0062] Finally, the component assembly fixture 30 is removed from the assembly component 2 and retrieved from the maintenance hole 24 of the storage box 21. Thus, the assembly of the assembly component 2 relative to the target component 1 is completed.

[0063] The above describes the embodiments of the present invention, which have the following features.

[0064] like Figures 8-10 As shown, the component assembly fixture 30 is a fixture used to assemble component 2 onto object component 1 using multiple bolts 3. The component assembly fixture 30 includes: a fixture body 31 that temporarily holds the assembly component 2; and multiple positioning guides 32 that respectively position the multiple bolt through holes 6 of the assembly component 2 into the multiple threaded holes 23 of the object component 1. Based on the above structure, the multiple positioning guides 32 can be used to position the multiple bolt through holes 6 into the multiple threaded holes 23, thus allowing the assembly component 2 to be easily assembled onto the object component 1 using multiple bolts 3 regardless of the working environment.

[0065] It should be noted that the component assembly fixture 30 includes at least one positioning guide 32. Therefore, the component assembly fixture 30 may include multiple positioning guides 32 as in this embodiment, or it may include only one positioning guide 32.

[0066] And, as Figure 7 As shown, the fixture body 31 has multiple tool insertion holes 38 corresponding to multiple bolt through holes 6. Based on the above structure, the assembly element 2 can be directly assembled to the object element 1 using multiple bolts 3 while the fixture body 31 temporarily holds the assembly element 2.

[0067] And, as Figure 4 , Figure 6 as well as Figure 7 As shown, a tool guide groove 37 is formed in the clamp body 31, extending in such a way that two of the openings 38a of the plurality of tool insertion holes 38 are connected. According to the above structure, the hex wrench R can be easily moved from one of the two openings 38a of the plurality of tool insertion holes 38 to the other.

[0068] And, as Figure 6As shown, the clamp body 31 has a tool guide groove 37 that extends in a ring shape in such a way that the openings 38a of the multiple tool insertion holes 38 are interconnected. According to the above structure, the hex wrench R can be easily moved between the openings 38a of the multiple tool insertion holes 38.

[0069] And, as Figure 6 As shown, the tool guide groove 37 is formed continuously. Based on the above structure, the direction of the hexagonal wrench R when moving the tool between the openings 38a of the multiple tool insertion holes 38 is not limited.

[0070] And, as Figure 7 As shown, with the jig body 31 temporarily holding the assembly element 2, multiple head receiving spaces E are formed between the assembly element 2 and the jig body 31. These multiple head receiving spaces E respectively receive the heads 3a of multiple bolts 3 inserted into multiple bolt through holes 6 of the assembly element 2. The jig body 31 has a jig-side bolt facing surface 34d, which restricts the vertical movement of the heads 3a by being opposite to the heads 3a of each bolt 3 received in each head receiving space E in the vertical direction, which is the bolt insertion direction. Similarly, the assembly element 2 has a component-side bolt facing surface 5d, which restricts the vertical movement of the heads 3a by being opposite to the heads 3a of each bolt 3 received in each head receiving space E in the vertical direction. The distance between each jig-side bolt facing surface 34d and the corresponding component-side bolt facing surface 5d is larger than the vertical dimension 3d of the corresponding head 3a. Based on the above structure, the assembly element 2 can be temporarily held in the fixture body 31 with multiple bolts 3 pre-inserted into the multiple bolt through holes 6 of the assembly element 2.

[0071] Furthermore, the component assembly fixture 30 includes multiple positioning guides 32. Each positioning guide 32 has a guide surface 40 that can contact the outer peripheral surface 22b of the assembly base 22, which is a cylindrical portion of the object component 1, having corresponding threaded holes 23. Based on the above structure, with a simple structure, multiple bolt through holes 6 can be positioned in multiple threaded holes 23 using multiple positioning guides 32.

[0072] And, as Figure 11As shown, the component assembly method for assembling the assembly component 2 to the target component 1 using multiple bolts 3 includes temporarily holding the assembly component 2 in the fixture body 31 of the component assembly fixture 30 (S110), and using multiple positioning guides 32 to position the multiple bolt through holes 6 of the assembly component 2 to the multiple threaded holes 23 of the target component 1 respectively (S120). According to the above method, multiple positioning guides 32 can be used to position the multiple bolt through holes 6 to the multiple threaded holes 23 respectively, so regardless of the working environment, the assembly component 2 can be easily assembled to the target component 1 using multiple bolts 3.

[0073] Furthermore, after inserting multiple bolts 3 into the multiple bolt through holes 6 of the assembly element 2 (S100), the assembly element 2 is temporarily held in the fixture body 31 (S110). According to the above method, multiple bolts 3 can be inserted into the multiple bolt through holes 6 of the assembly element 2 before the multiple positioning guides 32 are used to position the multiple bolt through holes 6 of the assembly element 2 into the multiple threaded holes 23 of the object element 1.

[0074] And, as Figure 10 As shown, while the assembly component 2 is temporarily held in the fixture body 31, multiple bolts 3 are directly fastened to multiple threaded holes 23 of the object component 1 (S130).

[0075] The preferred embodiments of the present invention have been described above, and these embodiments can be modified as follows.

[0076] Figure 1 The storage box 21 shown is depicted to illustrate a situation where the working environment is poor when assembling the assembly component 2 to the object component 1, and is not intended to limit the invention of this application through the storage box 21 and the maintenance hole 24.

[0077] In this embodiment, the assembly element 2 is assembled onto a plurality of assembly bases 22 of the object element 1. However, the assembly element 2 may also be assembled onto the object element body 20 of the object element 1. In this case, in order for the plurality of positioning guides 32 of the component assembly fixture 30 to perform their positioning function, it is preferable to provide a protrusion or recess near the threaded hole 23 formed in the object element 1.

[0078] This application claims priority based on Japanese Application Special Purpose 2020-139783, filed on August 21, 2020, the entire disclosure of which is incorporated herein by reference.
