[0042] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0043] In this text, the first direction X, the second direction Y, and the third direction Z are directions that intersect each other. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other.

[0044] This disclosure provides an auxiliary inspection fixture 1 for vehicles. See also... Figure 1 The vehicle includes a body, which has longitudinal beams 2 and fenders 3. The longitudinal beams 2 extend along a first direction X and have mounting surfaces, while the fenders 3 have mating surfaces. The fenders 3 and longitudinal beams 2 are spaced apart along a second direction Y and spaced apart along a third direction Z. See also Figure 2 , Figure 3 The auxiliary testing fixture 1 includes a base 11, an adjustment assembly 12, and a testing assembly 13. The base 11 is fixed to a mounting surface. The adjustment assembly 12 includes an adjustment seat 121, at least one first adjustment member 122, and a first fixing member 123. The adjustment seat 121 is disposed on the base 11, and the first adjustment member 122 is located between the base 11 and the adjustment seat 121. The base 11, the first adjustment member 122, and the adjustment seat 121 are distributed along a third direction Z. The first fixing member 123 passes through the adjustment seat 121 and the first adjustment member 122 and is detachably connected to the base 11. The testing assembly 13 includes a connecting seat 131 and a testing block 132. The connecting seat 131 is located on the side of the adjustment seat 121 away from the first adjustment member 122 and is connected to the testing block 132. The testing block 132 has a testing surface 1321 for mating with a mating surface.

[0045] In the embodiments of this disclosure, after the fender 3 of the vehicle is installed, by installing the auxiliary inspection fixture 1 on the longitudinal beam 2, the base 11 is fixed on the mounting surface. After the inspection surface 1321 of the inspection block 132 mates with the mating surface of the fender 3, the operator can use a surface difference gauge to measure the surface difference between the mating surface and the inspection surface 1321, and then use a gap gauge to measure the gap between the mating surface and the inspection surface 1321. This facilitates the rapid detection and monitoring of the installation accuracy of the fender 3, reduces the impact on the installation of surrounding parts (such as combination lights and their surrounding parts), improves the stability of the surface difference of the mating gap of the surrounding parts of the fender 3, reduces the probability of vehicle rework, improves production efficiency, reduces costs, and helps improve the overall vehicle assembly quality. Meanwhile, by setting adjustment components 12 on the auxiliary inspection fixture 1, the number of first adjustment components 122 can be increased or decreased as needed, making the position of the inspection block 132 adjustable in the third direction Z. On the one hand, this facilitates the auxiliary inspection fixture 1 to inspect and monitor the installation accuracy of the fender 3 on different types of vehicles, improving the versatility and flexibility of the auxiliary inspection fixture 1. On the other hand, during the production process, it can solve the problem of inaccurate inspection caused by the deviation of the auxiliary inspection fixture 1 itself, improving the stability of the production process.

[0046] In one embodiment of this disclosure, the longitudinal beam 2 of the vehicle can be a front longitudinal beam, and the fender 3 of the vehicle can be a front fender, that is, the longitudinal beam 2 and the fender 3 are located in the front part of the vehicle. In one example, there are two longitudinal beams 2, which are arranged parallel to each other along a first direction X. There are two fenders 3, which are spaced apart along a second direction Y and symmetrically arranged along the plane formed by the first direction X and the third direction Z. The longitudinal beam 2 is located between the two fenders 3. There are two auxiliary inspection fixtures 1, which are symmetrically arranged along the plane formed by the first direction X and the third direction Z. One auxiliary inspection fixture 1 is installed on a longitudinal beam 2 and inspects a fender 3. The base 11 is fixed to the mounting surface, and a detection surface 1321 mates with a mating surface. In this way, the installation accuracy of the two front fenders 3 of the same vehicle can be inspected and monitored simultaneously by two auxiliary fixtures, so as to improve the inspection efficiency and thus improve the production efficiency of the vehicle.

[0047] In one embodiment of this disclosure, the surface difference gauge has a specification of 0 mm to ensure that the inspection surface 1321 and the mating surface are parallel. The gap gauge has a measuring range of 5 mm to ensure a reasonable gap between the mating surface and the inspection surface 1321 (for example, the acceptable gap between the mating surface and the inspection surface 1321 is 3 mm).

[0048] In one embodiment of this disclosure, the operator can use a surface difference gauge to measure the surface difference between the inspection surface 1321 and the mating surface along the second direction Y and the third direction Z, so that the inspection surface 1321 and the mating surface are parallel surfaces along the second direction Y and the third direction Z, respectively. The operator can use a gap gauge to measure the gap between the mating surface and the inspection surface 1321 along the first direction X, and the acceptable gap value is 3mm. If the surface difference between the inspection surface 1321 and the mating surface along the second direction Y and the third direction Z is not 0mm, or if the gap between the mating surface and the inspection surface 1321 along the first direction X is not 3mm, then there is a problem with the installation of the fender 3, and it is necessary to use a straightening tool to correct it until the measurement result meets the requirements.

[0049] In one embodiment of this disclosure, the base 11 can be a plate-like structure or a block-like structure. The shape of the base 11 can be a geometric shape such as a prism, pyramid, frustum, or pyramid. The adjusting seat 121 can be a plate-like structure or a block-like structure.

[0050] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 , Figure 5 The adjustment assembly 12 also includes a movable block 124, at least one second adjustment member 125, and a second fixing member 126. The movable block 124 is located between the adjustment seat 121 and the connecting seat 131 and is movable along the second direction Y. The second adjustment member 125 and the movable block 124 are distributed along the second direction Y. The second fixing member 126 passes through the adjustment seat 121 and is detachably connected to the movable block 124 by the second adjustment member 125 and the second fixing member 126. Thus, the distance between the movable block 124 and the adjustment seat 121 along the second direction Y can be adjusted by the second adjustment member 125 and the second fixing member 126, allowing the connecting seat 131 and the detection block 132 to adjust their distance from the fender 3 along the second direction Y, further improving the versatility and flexibility of the auxiliary detection fixture 1.

[0051] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 , Figure 5The adjustment assembly 12 also includes at least one third adjustment member 127 and a third fixing member 128. The movable block 124 is movable along the first direction X. The third adjustment member 127 and the movable block 124 are distributed along the first direction X. The third fixing member 128 passes through the adjustment seat 121 and is detachably connected to the movable block 124 by the third adjustment member 127 and the third fixing member 128. In this way, the distance between the movable block 124 and the adjustment seat 121 along the first direction X can be adjusted by the third adjustment member 127 and the third fixing member 128, so that the connecting seat 131 and the detection block 132 can be adjusted along the first direction X, further improving the versatility and flexibility of the auxiliary detection fixture 1.

[0052] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 , Figure 5 The adjusting base 121 includes a base plate 1211, a first fixing part 1212, and a second fixing part 1213. The first fixing part 1212 and the second fixing part 1213 are located on the side of the base plate 1211 away from the base 11. The first fixing part 1212 extends along a first direction X and is located directly below the connecting base 131. The second fixing part 1213 extends along a second direction Y. A second adjusting member 125 is located between the first fixing part 1212 and the movable block 124. A second fixing member 126 passes through the first fixing part 1212 and is detachably connected to the movable block 124 along with the second adjusting member 125. A third adjusting member 127 is located between the second fixing part 1213 and the movable block 124. A third fixing member 128 passes through the second fixing part 1213 and is detachably connected to the movable block 124 along with the third adjusting member 127. Thus, the first fixing part 1212 and the second fixing part 1213 can clamp the second adjusting member 125, and the second fixing part 1213 and the movable block 124 can clamp the third adjusting member 127, thereby increasing the structural stability of the auxiliary testing fixture 1.

[0053] In one embodiment of this disclosure, the first fixing member 123 may include a fixing bolt and a fixing washer. The fixing bolt includes an integrally connected bolt shank and bolt cap. The bolt shank and the fixing washer are coaxially engaged. The bolt shank passes through the base plate 1211 and is threadedly connected to the base 11 via the first adjusting member 122. The fixing washer is clamped between the base plate 1211 and the bolt cap. The bolt cap may have a countersunk hole, the shape of which may be an inner triangle, an inner square, an inner hexagon, etc., to facilitate the detachable connection of the first fixing member 123. There may be multiple first fixing members 123, which are distributed circumferentially along the base plate 1211 and extend in the third direction Z. For example, there may be two, three, four, five, etc., first fixing members 123 to increase the connection performance between the base plate 1211 and the base 11. The structures of the second fixing member 126 and the third fixing member 128 are similar to those of the first fixing member 123 and will not be described in detail here. The second fixing member 126 can be threadedly connected to the movable block 124 and extends along the second direction Y, and the third fixing member 128 can also be threadedly connected to the movable block 124 and extends along the first direction X. In some other embodiments of this disclosure, the first fixing member 123 may only include a fixing bolt, and both the second fixing member 126 and the third fixing member 128 include a fixing bolt and a fixing washer.

[0054] In one embodiment of this disclosure, see Figure 2 , Figure 5 The first fixing part 1212 has a first strip hole 1214 for the second fixing member 126 to pass through, and the length direction of the first strip hole 1214 is the second direction Y. The second fixing part 1213 has a second strip hole 1215 for the third fixing member 128 to pass through, and the length direction of the second strip hole 1215 is the first direction X. Thus, by providing the first strip hole 1214 on the first fixing part 1212, after the movable block 124 is adjusted along the first direction X, it is convenient for the second fixing part 1213 to pass through the first strip hole 1214 and be threadedly connected to the movable block 124; by providing the second strip hole 1215 on the second fixing part 1213, after the movable block 124 is adjusted along the second direction Y, it is convenient for the third fixing part to pass through the second strip hole 1215 and be threadedly connected to the movable block 124.

[0055] In one embodiment of this disclosure, see Figure 2The adjusting assembly 12 also includes a fastener 129, which is detachably connected to the adjusting seat 121 through the movable block 124. The structure of the fastener 129 can be similar to that of the first fixing member 123. The number of fasteners 129 can be at least one; for example, there can be one, two, three, four, etc. Multiple fasteners 129 are distributed circumferentially at intervals along the movable block 124. The fasteners 129 can extend along a third direction Z to facilitate threaded connection with the base plate 1211 through the movable block 124. To accommodate the threaded connection between the fastener 129 and the base plate 1211 after the movable block 124 is adjusted along the first direction X or the second direction Y, the movable block 124 can be provided with a through hole. The diameter of the through hole is larger than the outer diameter of the bolt shank of the fastener 129, so as to achieve the threaded connection between the fastener 129 and the base plate 1211 after the movable block 124 is adjusted along the first direction X or the second direction Y. In this way, the movable block 124 can be more stably fixed by the fastener 129, which improves the structural stability of the auxiliary detection fixture 1.

[0056] In one embodiment of this disclosure, see Figure 4 The movable block 124 has a plate-like structure with a notch, so that the movable block 124 exposes the first fixing member 123, preventing interference between the movable block 124 and the first fixing member 123 and improving practicality.

[0057] In one embodiment of this disclosure, see Figure 5 , Figure 6 The first adjusting member 122 is a first shim, which is clamped between the base 11 and the bottom plate 1211; the second adjusting member 125 includes a second shim, which is clamped between the first fixing part 1212 and the movable block 124; the third adjusting member 127 includes a third shim, which is clamped between the second fixing part 1213 and the movable block 124; there can be multiple first, second, and third shims, and the thickness of each first, second, and third shim is 0.1mm to 5mm. For example, the thickness of each first, second, and third shim can be 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm. Thus, by adding or removing the corresponding shims, the movable block 124 can be adjusted in multiple dimensions along the first direction X, the second direction Y, and the third direction Z, so that the detection block 132 can be adjusted in multiple dimensions along the first direction X, the second direction Y, and the third direction Z, thereby improving the versatility and flexibility of the auxiliary detection fixture 1.

[0058] In one embodiment of this disclosure, the number of first gaskets can be 15; wherein 10 first gaskets have a thickness of 0.1 mm, 2 first gaskets have a thickness of 0.5 mm, and 3 first gaskets have a thickness of 1 mm. The number of second gaskets can be 15; wherein 10 second gaskets have a thickness of 0.1 mm, 2 second gaskets have a thickness of 0.5 mm, and 3 second gaskets have a thickness of 1 mm. The number of third gaskets can be 15; wherein 10 third gaskets have a thickness of 0.1 mm, 2 third gaskets have a thickness of 0.5 mm, and 3 third gaskets have a thickness of 1 mm. Thus, the first, second, and third gaskets have various specifications to choose from, so as to adjust the position of the detection block 132 according to the installation accuracy of the fender 3, which is beneficial to improving the detection accuracy of the auxiliary detection fixture 1.

[0059] In one embodiment of this disclosure, at least one of the second and third gaskets may have a notch facing the base plate 1211. This allows for the addition or removal of the second or third gasket without separating the second fastener 126 and the third fastener 128 from the movable block 124, facilitating the installation and removal of the second or third gasket.

[0060] In one embodiment of this disclosure, see Figure 2 , Figure 3 The connecting seat 131 includes a seat body 1311 and a connecting part 1312. The seat body 1311 is located on the side of the movable block 124 away from the base 11 and is connected to the movable block 124. One end of the connecting part 1312 is connected to the seat body 1311, and the other end is connected to the side of the detection block 132 away from the detection surface 1321. The connecting part 1312 is inclined toward the detection block 132 in a direction away from the seat body 1311. In one example, the seat portion 1311 includes an integrally connected body portion and an auxiliary portion, which are distributed along a second direction Y. The distance from the body portion to the movable block 124 is greater than the distance from the auxiliary portion to the movable block 124. The auxiliary portion has a plurality of positioning bolts and a plurality of positioning pins that are alternately distributed along its circumference. For example, there are two positioning bolts and two positioning pins, one of which is a diamond-shaped pin and the other is a cylindrical pin. The positioning bolts pass through the auxiliary portion and are threaded to the movable block 124, and the positioning pins pass through the auxiliary portion and are inserted into the movable block 124 to realize the connection between the connecting seat 131 and the movable block 124.

[0061] In one embodiment of this disclosure, see Figure 2 , Figure 3The connecting part 1312 includes a first end, a main body, and a second end that are integrally connected in sequence. The first end is connected to the main body, and the second end is connected to the detection block 132. The first end has a plurality of connecting bolts and a plurality of connecting pins that are alternately distributed along its circumference. For example, there are two connecting bolts and two connecting pins. One connecting pin is a diamond-shaped pin and the other is a cylindrical pin. The connecting bolts pass through the first end and are threaded to the main body. The connecting pins pass through the first end and are inserted into the main body to realize the connection between the connecting part 1312 and the connecting seat 131.

[0062] The second end has multiple fastening bolts and multiple fastening pins that are alternately distributed along its circumference. For example, there are two fastening bolts and two fastening pins. One fastening pin is a diamond-shaped pin and the other is a cylindrical pin. The fastening bolts pass through the second end and are threaded to the side of the detection block 132 away from the detection surface 1321. The fastening pins pass through the second end and are inserted into the side of the detection block 132 away from the detection surface 1321, so as to realize the connection between the connecting part 1312 and the detection block 132.

[0063] In one embodiment of this disclosure, the connecting seat 131 may further include reinforcing ribs, which are integrally connected to the main body and the auxiliary part, respectively, so as to increase the structural strength of the connecting seat 131.

[0064] In one embodiment of this disclosure, see Figure 2 A support bolt 14 is threadedly connected to the side of the main body away from the movable block 124. A support nut is threadedly connected to the support bolt 14. The support nut abuts against the main body. The support bolt 14 is used to hold the hood of the vehicle. When checking the installation accuracy of the fender 3, the hood is held in place by the support bolt 14 to improve the reliability of the auxiliary testing fixture 1.

[0065] In one embodiment of this disclosure, see Figure 2 , Figure 7 The detection surface 1321 of the detection block 132 is an arc surface. The curvature of the arc surface can be designed to match the arc surface of the fender 3, and is not limited here.

[0066] In one embodiment of this disclosure, see Figure 3 The base 11 has a positioning element 111 on the side away from the adjusting seat 121, and the mounting surface has positioning holes for engaging with the positioning element 111. For example, the positioning element 111 can be a fixing pin, and the number of fixing pins can be multiple, such as two, three, or four. In one example, there are two fixing pins, one of which is a cylindrical pin and the other is a diamond-shaped pin. The fixing pins are fixedly connected to the side of the base 11 away from the adjusting seat 121. The engagement of the fixing pins with the positioning holes facilitates the fixing of the auxiliary inspection fixture 1 to the mounting surface, thereby enabling a detachable connection between the auxiliary inspection fixture 1 and the longitudinal beam 2.

[0067] In one embodiment of this disclosure, see Figure 2 , Figure 3 The base 11 has a connecting hole and a set screw hole 112. The positioning member 111 is fitted into the connecting hole, and the set screw hole 112 communicates with the connecting hole. In this way, by setting a bolt in the set screw hole 112, and by the bolt abutting against the positioning member 111, the positioning stability of the auxiliary detection fixture 1 and the longitudinal beam 2 can be improved.

[0068] In one embodiment of this disclosure, see Figure 3 The base 11 has multiple limiting holes 113 on the side away from the movable block 124. For example, the number of limiting holes 113 can be two, three, four, five, etc. The mounting surface of the longitudinal beam 2 can be provided with limiting posts for cooperating with the limiting holes 113. In this way, the positioning stability of the auxiliary detection fixture 1 and the longitudinal beam 2 can be further improved, which facilitates the improvement of the detection accuracy of the auxiliary detection fixture 1.
