Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the inspection method described in Patent Document 1, it is necessary to prepare a dedicated jig of the actual size for each door corresponding to the vehicle type of the automobile, in which a jig adapted to the length of the body flange surface and the like is provided on a substrate having the size of the door of the actual vehicle. Therefore, a large working space is required for changing the jig, so-called setup change, corresponding to different vehicle types or inspection targets, or for replacing the jig when using and not using it, and there is also a problem that the man-hours and time for setup change of the jig are large.

[0005] The present invention has been made in view of the above, and its purpose is to provide a jig device for holding an object to be inspected in the inspection of automobile parts, etc., that is compact, does not require a large workspace for changing the jig setup between different vehicle types or objects to be inspected, and reduces the man-hours and time required for changing the jig setup. [Means for solving the problem]

[0006] To achieve the above objective, the following solutions were implemented for a jig device used to hold objects to be inspected during the inspection of automobile parts and the like.

[0007] The first invention provides a jig device for holding an object to be inspected, comprising: a first engaging tool that can engage with a part of the object to be inspected; a second engaging tool that is separated from the first engaging tool and can engage with another part of the object to be inspected; and first and second bases that support the first and second engaging tools respectively, and are spaced apart from each other, and are switchable between a use position where they are positioned inside a predetermined inspection surface specific to the object to be inspected and engage with the object to be inspected, and a non-use position where they are positioned away from the inspection surface and do not engage with the object to be inspected.

[0008] In other words, in the first invention, the first and second bases support the first and second engaging devices, which are separated from each other and capable of engaging with a part of the object to be inspected, respectively, in a switchable position between a use position where they are positioned inside a predetermined inspection surface specific to the object to be inspected and engage with the object to be inspected, and a non-use position where they are positioned away from the inspection surface and do not engage with the object to be inspected. By switching between the use position and the non-use position of each base, each engaging device can be separated and replaced individually, eliminating the need to replace them as a whole. This makes it possible to provide a compact jig device with reduced man-hours and time required for changing the jig between use and non-use.

[0009] In the second invention, in the first invention, the first engaging device is capable of engaging with a part of the object to be inspected along the shape of the object to be inspected, and the second engaging device is capable of engaging with another part of the object to be inspected along the shape of the object to be inspected, and the first and second bases support the first and second engaging devices, respectively, by positioning them within the surfaces that intersect with the inspection surface and are spaced apart from the inspection surface in the unused position, so as not to engage with the object to be inspected.

[0010] In the second invention, in the first invention, the first base supporting a first engaging device that can engage with a part of the object to be inspected along the shape of the object to be inspected, and the second base supporting a second engaging device that can engage with another part of the object to be inspected along the shape of the object to be inspected, are switched by an operation to position each engaging device inside the surface that intersects with the inspection surface in the unused position so that it intersects with the direction along the shape of the object to be inspected. As a result, each engaging device, when viewed from the inspection surface, is superimposed on itself, reducing the projection size of each engaging device on the inspection surface. Therefore, a compact jig device can be provided that requires less man-hours and time for changing the jig between use and non-use.

[0011] In the third invention, in the first invention, the first and second bases are arranged spaced apart from each other in the horizontal direction.

[0012] Since the first and second bases are arranged spaced apart from each other in the horizontal direction, the spacing between the bases can be easily adjusted during jig setup changes according to the different horizontal lengths of different inspection targets. This makes it possible to easily provide a compact jig device that requires less man-hours and time for setup changes to accommodate different inspection targets.

[0013] In the fourth invention, in the first invention, the first base includes a first columnar body whose first side surface is provided with the first engagement and whose bottom surface is pivotally supported so as to be rotatable about an axis in a direction intersecting the bottom surface, and the second base includes a second columnar body whose second side surface is provided with the second engagement and whose bottom surface is pivotally supported so as to be rotatable about an axis in a direction intersecting the bottom surface, and the first and second engagements are supported so as to be switchable between the usage position and the non-usage position by the rotation of each columnar body.

[0014] The first and second columnar bodies, which are pivotally supported by the first and second bases and are rotatable about an axis intersecting the bottom surface, are equipped with first and second engagings on their first and second sides, respectively. Therefore, by rotating each columnar body, the first engaging on the first side and the second engaging on the second side can be easily switched between a use position where they are positioned inside the inspection surface and a non-use position where they are positioned away from the inspection surface. This allows for the provision of a compact jig device with a simple structure that requires minimal man-hours and time for changing the jig between use and non-use.

[0015] The fifth invention further provides a locking mechanism in the fourth invention that can fix the first and second columnar bodies so as not to rotate.

[0016] The jig device further includes a locking mechanism that can fix the first and second columnar bodies in place to prevent rotation. Therefore, the first and second engaging devices provided on the first side of each columnar body are fixed so as not to rotate from their use position for engaging with the object to be inspected, thus preventing any inconvenience such as the object to be inspected becoming detached during use.

[0017] In the sixth invention, in the fourth invention, the shapes of the first and second columnar bodies are rectangular prisms, the first columnar body is provided with a third engaging device on a side surface different from the first side surface that can engage with a part of another object to be inspected, and the second columnar body is provided with a fourth engaging device on a side surface different from the second side surface that can engage with another part of another object to be inspected.

[0018] The first and second columnar bodies each have four sides of a rectangular prism, and the first columnar body is equipped with a third engaging device on a side different from the first side that can engage with a part of another object to be inspected, and the second columnar body is equipped with a fourth engaging device on a side different from the second side that can engage with another part of the object to be inspected. Therefore, by rotating each columnar body, it is easy to switch between supporting the first to fourth engaging devices in use and in non-use positions, thus providing a compact jig device with a simple structure that reduces the man-hours and time required for changing the setup of the jig to accommodate multiple objects to be inspected.

[0019] Furthermore, since the four sides of the rectangular prism-shaped columnar body can each be equipped with an engagement device corresponding to a different inspection target, and can be easily switched by rotating each columnar body, a compact jig device that can handle up to four inspection targets and requires minimal setup time and effort can be easily provided with a simple structure.

[0020] In the seventh invention, in the fourth invention, the first and second engaging members each include a jig plate, and are arranged on the first and second columnar bodies via the jig plates.

[0021] Since the first and second engaging devices include their respective jig plates and are arranged on the first and second columnar bodies via these jig plates, rearranging the engaging devices to accommodate changes in the shape specifications of the object being inspected only requires replacing the jig plates themselves, and there is no need to replace the entire columnar body or base equipped with the engaging devices. Therefore, it is possible to provide a jig device that requires less man-hours and time for changing the setup of the jig due to rearranging the engaging devices.

[0022] In the eighth invention, in the first invention, the first and second engaging devices engage with the rubber joint of the weatherstrip.

[0023] Since the first and second engaging tools engage with the rubber joint of the weatherstrip of an automobile, it is possible to perform an inspection of the weatherstrip that reproduces the state of being assembled to the vehicle. Therefore, it is possible to provide a jig device for inspecting a weatherstrip that is compact and has a small number of man-hours and time for changing the setup of the jig when used and not used.

Advantages of the Invention

[0024] According to the present invention, there is provided a jig device for holding an inspection object in an inspection of automobile parts or the like, which is compact and does not require a large working space for changing the setup of the jig corresponding to different vehicle types or inspection objects or when used and not used, and has a small number of man-hours and time for changing the setup of the jig.

Modes for Carrying Out the Invention

[0026] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Note that the following description of the preferred embodiments is merely illustrative in nature.

[0027] (Jig and fixture) Figure 1 shows the configuration of a jig device 1 according to an embodiment of the present invention. The jig device 1 is used to hold objects to be inspected during the inspection of various products and parts. The jig device 1 can be used, for example, to inspect weatherstrips, which are automotive parts.

[0028] As shown in Figure 1, the jig device 1 comprises a pair of bases 3a and 3b arranged on a horizontal floor surface, and a pair of engaging members 2a and 2b supported by each base 3a and 3b for holding the object to be inspected T on the inspection surface TS in front of the jig device 1. The inspection surface TS is a virtual surface unique to the object to be inspected T, on which the object to be inspected T is positioned during inspection, and includes surfaces that extend along the shape of the object to be inspected T. The bases 3a and 3b are spaced apart horizontally to the left and right according to the size of the object to be inspected T. In the following, corresponding components will be denoted by the same or similar reference numerals, and for example, the pair of bases 3a and 3b may be collectively referred to as base 3.

[0029] (Base) As shown in Figures 1 and 2, the base 3 consists of a rod-shaped member made of a round metal pipe (hereinafter sometimes referred to as a frame member), and includes a rod-shaped leg portion 34 extending substantially horizontally in the front-rear direction perpendicular to the inspection surface TS, a rod-shaped column portion 35 extending vertically upward from the approximate center of the leg portion 34, a rectangular column 31 whose bottom surface is supported so as to be rotatable around the column portion 35 as an axis, a rotation mechanism 32 for rotating the rectangular column 31, and a locking mechanism 33 that can fix the rectangular column 31 so as not to rotate. Furthermore, the approximate centers of the pair of leg portions 34a and 34b are connected to each other by connecting members 36 extending horizontally to the left and right to stabilize the arrangement of the base 3a and 3b. Similarly, the upper ends of the pair of column portions 35a and 35b are connected to each other by connecting members 37 extending horizontally to the left and right.

[0030] (square prism) As shown in Figure 2, the rectangular prism 31 has a hollow structure in which frame members are placed only on each edge, and has upper and lower bottom surfaces 315 and 316, and four side surfaces 311 to 314 on which the engaging devices 2 can be placed. The rectangular prism 31 is also rotatable around a column portion 35 that penetrates vertically through approximately the center of the bottom surfaces 315 and 316, and each engaging device 2 placed on the side surfaces 311 to 314 can be switched between a use position in which the engaging device 2 is placed inside the inspection surface TS and a non-use position in which it is placed away from the inspection surface TS. In other words, each side surface 311 to 314 of the rectangular prism 31 can be switched between a use position in which the engaging device 2 is placed inside the inspection surface TS at a front front position parallel to the inspection surface TS, and a non-use position in which the engaging device 2 is placed away from the inspection surface TS at a front rear position parallel to the inspection surface TS and left and right positions perpendicular to the inspection surface TS.

[0031] Specifically, on the sides 311a to 314a of one rectangular prism 31a, engaging devices 2a1 to 2a4 that can engage with parts of the inspection targets T1 to T4 are arranged, and on the sides 311b to 314b of the other rectangular prism 31b, engaging devices 2b1 to 2b4 that can engage with other parts of the inspection targets T1 to T4 are respectively arranged. The rectangular prisms 31a and 31b are rotated around the columnar sections 35a and 35b as axes, thereby switching the engaging devices 2a1 to 2a4 and 2b1 to 2b4 on their respective four sides between a usage position and a non-usage position, so that they can engage with the four inspection targets T1 to T4 in the usage position and not engage in the non-usage position.

[0032] (Rotation mechanism) The rotating mechanism 32 is for rotating the rectangular prism 31 around the approximate center of the column portion 35 as an axis, and as shown in Figure 2(B), the column portion 35 is equipped with rotating mechanisms 32u and 32d on the upper and lower parts. The rotating mechanism 32u comprises a rotating part 320u that rotates around the axis, and upper and lower stoppers 325u and 326u positioned above and below the rotating part 320u to fix the vertical position of the rotating part 320u. The rotating part 320u is an annular cylindrical member, and the column portion 35 is passed through its opening so that it rotates around the column portion 35 as an axis. The rotating part 320u also has four rotating bars 321u to 324u, which are made of frame members that project horizontally and approximately vertically outward at approximately equal intervals along the circumferential direction of the cylindrical side surface. The rotating mechanism 32u is connected to the base surface 315 of the rectangular prism 31 by rotating bars 321u to 324u at approximately the midpoints of the intersecting sides of the base surface, and the rotating mechanism 32d is similarly connected to the base surface 316 of the rectangular prism 31, so that the rotating mechanism 32 and the rectangular prism 31 rotate as a single unit.

[0033] (Locking mechanism) The locking mechanism 33 is for fixing the rectangular prism 31 so that it does not rotate around the column portion 35 as an axis. As shown in Figure 2(A), it comprises a slide mechanism 331 provided on the column portion 35 above the rotation mechanism 32u, and a holding portion 332 connected to the slider portion of the slide mechanism 331. A commercially available slide mechanism 331 is used, and the slider portion is slidable vertically along the column portion 35. The holding portion 332 is an inverted U-shaped member with an opening that opens downwards, consisting of a pair of left and right frame members that extend vertically opposite to each other horizontally, and a frame member that horizontally connects the upper ends of the left and right frame members. When the holding portion 332 is slid downwards, the left and right frame members clamp one of the horizontal rotation bars 321u to 324u in the opening that opens downwards, restricting the lateral movement of the rotation bar and setting a locked state in which the rotation of the rectangular prism 31 is fixed. Furthermore, when the holding portion 332 is slid upward, the left and right frame members prevent the rotating bars 321u to 324u from being clamped in the opening, thus releasing the lock and allowing the horizontal rotating bars to move freely in the left and right directions.

[0034] (Engagement device) As shown in Figure 3, the engaging device 2 engages with a portion of the weatherstrip T, which is the object to be inspected, along its shape, for measuring, evaluating, and inspecting the rubber joint of the weatherstrip T. It comprises a jig plate 21 positioned on the side of the rectangular prism 31 of the base 3, and a jig 22 attached to the surface of the jig plate 21 to engage with the rubber joint of the weatherstrip T.

[0035] (Jig plate) As shown in Figures 3(A) and 3(B), the jig plate 21 is a flat, thin sheet of metal or resin with a roughly rectangular shape when viewed from the front, and has mounting holes at its four corners so that it can be attached to any side 311 to 314 of the rectangular prism 31 of the base 3 with screws or the like. The surface of the jig plate 21 also has multiple mounting holes for attaching multiple jigs 22 with screws or the like at predetermined positions that match the shape and dimensions of the weatherstrip T.

[0036] (jig) As shown in Figure 3(C), the jig 22 is a thin sheet of metal or resin with a roughly rectangular shape when viewed from the front. The roughly rectangular sheet is bent approximately 90 degrees in an L-shape along its longitudinal direction, approximately in the center of the width direction. It has a bottom surface 221 that connects to the jig plate 21 and a side surface 222 that contacts the weatherstrip T. The length, width, and height of each part of the jig 22 are set so that the shape and dimensions of the rubber joint of the weatherstrip T can be measured, evaluated, and inspected. The bottom surface 221 also has multiple mounting holes for attaching it to the jig plate 21 with screws or the like.

[0037] (How to use) Next, the method of using the jig device 1 for inspecting automotive weatherstrips will be explained using Figures 4 and 5.

[0038] (When examining weatherstrip T1) Figure 4 shows the inspection of a weatherstrip T1 for a specific vehicle model. First, the user slides the holding part 332 of the locking mechanism 33 upward to release the lock, allowing the rectangular prism 31 to rotate freely around the column part 35. Next, the user manually rotates the pair of rectangular prisms 31a and 31b by the desired angles to position the engaging devices 2a1 and 2b1, which are located on the sides 311a and 311b of the rectangular prisms 31a and 31b and correspond to the weatherstrip T1, at the usage position on the inspection surface TS. Then, the user slides the holding part 332 of the locking mechanism 33 downward to lock it, fixing the rectangular prisms 31a and 31b so that they do not rotate. In this state, the user can easily inspect the weatherstrip T1 by placing it inside the inspection surface TS and engaging it with the corresponding engaging devices 2a1 and 2b1 at the predetermined positions.

[0039] (When examining weatherstrip T2) Figure 5 shows the case where, after the inspection of weatherstrip T1 is completed, a weatherstrip T2 for a different vehicle type is inspected. The user slides the holding part 332 of the locking mechanism 33 of the base 3 upward again to release the lock, rotates the pair of rectangular prisms 31a and 31b 90 degrees to the left when viewed from the front of the inspection surface TS, and positions the engaging devices 2a2 and 2b2 corresponding to the weatherstrip T2, which are located on the adjacent sides 312a and 312b of the rectangular prism 31, at the usage position on the inspection surface TS. Then, the locking mechanism 33 is locked. In this state, the user can easily and quickly inspect the weatherstrip T2 by placing it inside the inspection surface TS and engaging it with the corresponding engaging devices 2a2 and 2b2 at the predetermined positions.

[0040] (summary) Thus, according to the embodiment of the present invention, the bases 3a and 3b support engaging devices 2a1 and 2b1, which are separated from each other and can engage with a part of the inspection target T1, respectively, in a switchable position between a use position where they are positioned inside the inspection surface TS specific to the inspection target T and engage with the inspection target T1, and a non-use position where they are positioned away from the inspection surface TS and do not engage with the inspection target T1. By switching the use position and non-use position of each base 3a and 3b, each engaging device 2a1 and 2b1 can be separated and replaced individually, and there is no need to replace them as a whole. Therefore, a compact jig device 1 can be provided that requires less man-hours and time for changing the setup of the jig 22 between use and non-use.

[0041] Furthermore, the base 3a, which supports an engaging device 2a1 that can engage with a part of the inspection target T1 along the shape of the inspection target T1, and the base 3b, which supports an engaging device 2b1 that can engage with another part of the inspection target T1 along the shape of the inspection target T1, are switched to position the engaging devices 2a1 and 2b1 inside the surface that intersects with the inspection surface TS when not in use, so that they intersect with the direction along the shape of the inspection target T1. As a result, the engaging devices 2a1 and 2b1, when viewed from the inspection surface TS, are superimposed on themselves, and the projection size of the engaging devices 2a1 and 2b1 on the inspection surface TS can be reduced, thus providing a compact jig device 1 with low man-hours and time required for changing the setup of the jig 22 between use and non-use.

[0042] Since the bases 3a and 3b are arranged spaced apart from each other in the horizontal direction, the spacing between the bases 3a and 3b can be easily adjusted according to the different horizontal lengths of the different inspection targets T during setup changes of the jig 22. This makes it possible to easily provide a compact jig device 1 that requires less man-hours and time for setup changes of the jig 22 to accommodate different inspection targets T.

[0043] The rectangular prisms 31a and 31b, which are pivotally supported so as to be rotatable about an axis intersecting the bottom surfaces 315a and 315b, including the bases 3a and 3b, are equipped with engaging devices 2a1 and 2b1 on their sides 311a and 311b, respectively. By rotating each rectangular prism 31a and 31b, the engaging device 2a1 on side 311a and the engaging device 2b1 on side 311b can be easily switched between a use position where they are positioned inside the inspection surface TS and a non-use position where they are positioned away from the inspection surface TS. Thus, a compact jig device 1 with a simple structure can be provided, which requires less man-hours and time to change the setup of the jig 22 between use and non-use.

[0044] The jig device 1 is further equipped with a locking mechanism 33 that can fix the rectangular prisms 31a and 31b so as not to rotate. Therefore, the engaging devices 2a1 and 2b1 provided on the sides 311a and 311b of each rectangular prism 31a and 31b are fixed so as not to rotate from the position in which they engage with the object to be inspected T1. Thus, no inconvenience occurs during use, such as the object to be inspected T1 being released.

[0045] Each of the rectangular prisms 31a and 31b has four sides 311a to 314a and 311b to 314b. The rectangular prism 31a has an engaging device 2a2 on side 312a, which is different from side 311a, that can engage with a part of the object to be inspected T2, and the rectangular prism 31b has an engaging device 2b2 on side 312b, which is different from side 311b, that can engage with another part of the object to be inspected T2. By rotating each of the rectangular prisms 31a and 31b, it is easy to switch between supporting the engaging devices 2a1 to 2a2 and 2b1 to 2b2 in their usage and non-usage positions. This makes it possible to easily provide a compact jig device 1 with a simple structure that requires minimal man-hours and time for changing the setup of the jig 22 to accommodate multiple objects to be inspected T1 and T2.

[0046] Furthermore, since the four sides 311 to 314 of the rectangular prism 31 can each be equipped with engaging devices 2a1 to 2a4 and 2b1 to 2b4 corresponding to different inspection targets T1 to T4, they can be easily switched by rotating each rectangular prism 31. This makes it possible to easily provide a compact jig device 1 with a simple structure that can handle up to four inspection targets T1 to T4, and that requires less man-hours and time to change the setup of the jig 22.

[0047] Since the engaging devices 2a and 2b include their respective jig plates 21a and 21b and are arranged on the rectangular prisms 31a and 31b via their respective jig plates 21a and 21b, rearranging the engaging devices 2a and 2b to accommodate changes in the shape specifications of the object to be inspected T only requires replacing the jig plates 21a and 21b individually, and there is no need to replace the entire rectangular prisms 31a and 31b or bases 3a and 3b equipped with the engaging devices 2a and 2b. Therefore, a jig device 1 can be provided that requires less man-hours and time for changing the setup of jigs 22a and 22b due to rearranging the engaging devices 2a and 2b.

[0048] Since the engaging devices 2a and 2b engage with the rubber joints of the weatherstrip T of an automobile, it is possible to perform inspections of the weatherstrip T in a manner that replicates the state in which it is assembled on a vehicle. Therefore, a compact jig device 1 for inspecting automobile weatherstrips can be provided, which requires less man-hours and time for changing the setup of the jig 22 between use and non-use.

[0049] According to the present invention, a jig device 1 for holding a weatherstrip T in the inspection of a weatherstrip of an automobile part can be provided, which is compact and does not require a large workspace to change the setup of the jig 22 when it is in use or not in use, and the man-hours and time required to change the setup of the jig 22 are small, and the jig device 1 can be provided that can be adapted to different vehicle types or inspection targets, or when the jig 22 is in use or not in use.

[0050] (Base) Furthermore, the number of bases 3 in the jig device 1 is not limited to 2, but may be 3, 4, or other numbers depending on the size of the object to be inspected T. By increasing the number of bases 3, it is possible to easily accommodate larger objects to be inspected T in the horizontal direction parallel to the floor surface.

[0051] Furthermore, the arrangement of the multiple bases 3 is not limited to a horizontal direction parallel to the floor surface, but may also be in a direction substantially perpendicular to the floor surface. By arranging them in a direction substantially perpendicular to the floor surface, the multiple bases 3 can easily accommodate inspection targets T that are large in that direction.

[0052] Furthermore, when multiple bases 3 are arranged in a direction substantially perpendicular to the floor surface, the direction in which each column portion 35 extends is not limited to a direction substantially perpendicular to the floor surface, but may, for example, be in a horizontal direction parallel to the floor surface. In this way, by arranging the bottom surfaces 315 and 316 of the rectangular prism 31 with the column portion 35 as the axis of rotation on the left and right sides in the horizontal direction, the distance between the bottom surfaces 315 and 316 can be increased, making it easy to accommodate inspection targets T that are large in the horizontal direction.

[0053] Furthermore, the connecting members 36 and 37 of the base 3 may be adjustable in length. By using adjustable connecting members 36 and 37, the distance between the bases 3a and 3b can be easily changed, thus easily accommodating inspection targets T of various sizes.

[0054] (column) Furthermore, the shape of the columnar body of the base 3 is not limited to a square prism, but may be any polygonal prism such as a pentagonal prism or a hexagonal prism. A polygonal prism with a large number of sides allows for the placement of engagement devices 2 corresponding to the same number of inspection targets as the number of sides, thus enabling it to accommodate a larger number of different inspection targets T. This provides a jig device 1 with reduced man-hours and time required for changing the setup of the jig 22.

[0055] (Rotation mechanism) Furthermore, the rotation mechanism 32a of the base 3a and the rotation mechanism 32b of the base 3b may be linked to rotate the rectangular prism 31a and the rectangular prism 31b. Since the engaging device 2a1 of the rectangular prism 31a and the engaging device 2b1 of the rectangular prism 31b can be simultaneously positioned in their respective usage and non-usage positions, there is no need to position them individually, thus providing a jig device 1 with reduced man-hours and time for changing the setup of jigs 22a and 22b.

[0056] (Locking mechanism) Furthermore, the locking mechanism 33 of the jig device 1 may be omitted. By omitting the locking mechanism 33, the configuration of the jig device 1 can be simplified and manufactured at a lower cost.

[0057] The present invention is not limited to the embodiments described above, but includes various modifications to the embodiments described above, without departing from the spirit of the invention. [Explanation of symbols]
