[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] See Figures 1-7This utility model provides a fixture for inspecting the contour of an ambient light bracket. The ambient light bracket 100 satisfies the following conditions: the ambient light bracket 100 has a first inspection surface 103 and a second inspection surface 104 opposite to each other, and a mounting surface 105 connecting the first inspection surface 103 and the second inspection surface 104. The mounting surface 105 is provided with a first positioning connection structure 110 for cooperating with the vehicle body, that is, the ambient light bracket 100 is connected to the vehicle body through the first positioning connection structure 110. The inspection fixture provided in this embodiment includes a base 200, a carrier 300, a fixing device 400, a positioning device 600, and a go / no-go gauge 500. The base 200 includes a platform 220, and the carrier 300 is fixed to the platform 220. A first region on the top surface of the carrier 300 is provided with a second positioning connection structure 310 that cooperates with the first positioning connection structure 110. A second region on the top surface of the carrier 300 protrudes to form a first vertical surface 304 that conforms to the design contour of the first surface to be inspected 103. The fixing device 400 includes a base 401 fixedly connected to the platform 220 on one side of the carrier 300 and a clamping arm 403 movably connected to the base 401. The clamping arm 403 is used to clamp the ambient light bracket 100 on the carrier 300. The positioning device 600 includes a support base 610 fixedly connected to the table surface of the platform 220 on the side of the carrier 300 away from the base 401, and a positioning body rotatably connected to the support base 610. The side of the positioning body has a second elevation 641 that conforms to the design contour of the second surface to be inspected 104. When the ambient light bracket 100 is installed on the carrier 300, a first inspection gap is formed between the first surface to be inspected 103 and the first elevation 304, and a second inspection gap is formed between the second surface to be inspected 104 and the second elevation 641. The go / no-go gauge 500 has a first cylindrical end with a first diameter and a second cylindrical end with a second diameter, wherein the first diameter is smaller than the second diameter.
[0042] The working principle of the inspection fixture is as follows: First, the platform 220 is placed on a horizontal support surface such as a table or the ground. Then, the ambient light bracket 100 is installed on the carrier 300, and the ambient light bracket 100 is pressed and fixed by the clamping arm 403 of the fixing device 400. That is, the clamping arm 403 and the carrier 300 clamp the ambient light bracket 100. At this time, the ambient light bracket 100 is located in the first area of the carrier 300, and the first surface to be inspected 103 of the ambient light bracket 100 faces the first vertical surface 304 of the second area of the carrier 300. A first inspection gap is formed between the first vertical surface 304 and the first surface to be inspected 103. Then, the positioning body of the positioning device 600 is rotated so that the positioning body and the ambient light bracket 100 are on the same plane. That is, the positioning body is lowered from the raised state to the horizontal state. At this time, the second vertical surface 641 of the positioning body faces the second surface to be inspected 104 of the ambient light bracket 100, and a second inspection gap is formed between the second vertical surface 641 and the second surface to be inspected 104. Finally, the first and second cylindrical ends of the go / no-go gauge 500 are used to move along the first inspection gap to check whether the contour of the first inspection surface 103 of the ambient light bracket 100 is qualified, and the first and second cylindrical ends of the go / no-go gauge 500 are used to move along the second inspection gap to check whether the contour of the second inspection surface 104 of the ambient light bracket 100 is qualified.
[0043] It should be noted that the design contour of the first facade 304 being consistent with that of the first inspection surface 103 means that the actual contour of the first facade 304 is set to the theoretical contour of the first inspection surface 103. Similarly, the design contour of the second facade 641 being consistent with that of the second inspection surface 104 means that the actual contour of the second facade 641 is set to the theoretical contour of the second inspection surface 104. It is easy to understand that when both the first inspection surface 103 and the second inspection surface 104 of the actually manufactured ambient light bracket 100 have theoretical contours, the first inspection gap and the second inspection gap will both be gaps of equal width. Within the allowable deviation range, the actually formed gap satisfies the following condition: the thinner end of the go / no-go gauge 500, i.e., the first cylindrical end, is allowed to pass through, but the thicker end of the go / no-go gauge 500, i.e., the second cylindrical end, is not allowed to pass through. That is, when the inspection result using the inspection fixture is that the actually formed gap meets the above conditions, the contour of the inspection surface corresponding to the gap is deemed qualified; otherwise, it is deemed unqualified.
[0044] As can be seen from the above working principle, when inspecting the contour of the ambient light bracket, simply install the ambient light bracket 100 on the carrier 300. A simple operation can create an inspection gap corresponding to the surface to be inspected. Then, by using a go / no-go gauge 500 to move along the gap, the contour of the surface to be inspected can be judged intuitively and quickly, improving inspection efficiency. Furthermore, since the first facet 304 and the second facet 641 of the inspection fixture are designed to conform to the first surface to be inspected 103 and the second surface to be inspected 104 of the ambient light bracket 100, it can meet the requirements for inspecting the contour of irregularly shaped ambient light brackets 100.
[0045] like Figure 1 and Figure 7 As shown, in some embodiments, the inspection fixture may include a latch 700 fixed to the table surface of the platform 220. The latch 700 is used to engage the middle part of the go / no-go gauge 500. The latch 700 can be fixed to the platform 220 by fasteners such as screws. The latch 700 is used to store the go / no-go gauge 500. That is, when the go / no-go gauge 500 is not in use, it can be latched onto the latch 700, thereby storing the go / no-go gauge 500 in a predetermined position on the platform 220 for easy retrieval next time. Of course, in other embodiments, the go / no-go gauge 500 can also be stored in other ways. For example, a slot matching the shape of the go / no-go gauge 500 can be provided on the table surface of the platform 220, and the go / no-go gauge 500 can be placed in the slot for storage.
[0046] See Figure 2 and Figure 6 In some embodiments, the positioning body of the positioning device 600 may include a first block 630 and a second block 640 arranged in a T-shape and fixedly connected. The first block 630 is rotatably connected to the support base 610, and the second surface 641 is disposed on the side of the second block 640 away from the first block 630. The T-shape of the positioning body allows for a smaller volume, which helps reduce the weight of the positioning body and makes it easier for inspection personnel to lift the positioning body. Of course, in other embodiments, the positioning body may also be configured in other shapes, such as a door panel shape.
[0047] like Figure 6 As shown, when the second facade 641 of a single positioning element is insufficient to fully match the second surface 104 to be inspected of the ambient light bracket 100, the number of positioning elements can be set to two or more, so that these positioning elements together form a second facade 641 of sufficient length to meet the requirements. For example, in Figure 6 In the exemplary embodiment shown, two support bases 610 are provided, each support base 610 is connected to a positioning body, and when both positioning bodies are laid horizontally... Figure 6In the state shown, the side of the second block 640 away from the first block 630 is assembled to form a complete second facade 641 of sufficient length. It is easy to understand that after the inspection is completed, the two positioning bodies can be lifted separately without affecting each other.
[0048] In some embodiments, the top surface of the support base 610 may be provided with a threaded hole (not shown), and the first block 630 may be provided with a bolt hole (not shown) corresponding to the position of the threaded hole. When the positioning body is in the working position (i.e., horizontally laid down), the first block 630 and the support base 610 are fixed by fastening bolts 620 passing through the bolt holes. The fastening bolts 620 can better ensure that the positioning body does not move during the testing process, thus ensuring the reliability of the testing results. Of course, in other embodiments, the positioning body in the working position can also be prevented from moving in other ways. For example, a slot is provided on the side of the first block 630, and a through hole is opened on the support base 610 corresponding to the position of the slot on the side of the first block 630. The axis of the through hole is parallel to the rotation axis of the positioning body when it rotates relative to the support base 610. When the positioning body is in the working position, a locking pin passes through the through hole on the support base 610 and engages with the slot on the side of the first block 630, thus restricting the movement of the first block 630 relative to the support base 610.
[0049] To ensure the ambient light holder 100 is more securely held on the base 300, in some embodiments, the fixing device 400 may include a plurality of bases 401 arranged in a row, each base 401 being connected to a clamping arm 403. See also Figure 1 , Figure 2 and Figure 6 The number of clamping arms 403 can be set according to the specific situation of the first positioning connection structure 110 of the ambient light bracket 100, for example, in Figure 1 In the exemplary embodiment shown, the first positioning connection structure 110 includes one positioning post 102 and six riveting posts 101. Therefore, the number of clamping arms 403 can be correspondingly set to seven, one of which corresponds to the position of the positioning post 102, and the other six correspond to the positions of the riveting posts 101 respectively. Of course, in other embodiments, the number of clamping arms 403 can also be set to more than seven to achieve a better fixing effect on the ambient light bracket 100.
[0050] like Figure 6As shown, in some embodiments, the end of the clamping arm 403 on the outermost base 401 may be provided with a clamping bolt 404, which can better fix the position of the positioning post 102 of the ambient light bracket 100. To achieve a movable connection between the clamping arm 403 and the base 401, the clamping arm 403 and the base 401 can be connected by a clamp 402, that is, the clamp 402 is set on the base 401 and can clamp and fix the clamping arm 403. When the test is completed, the clamping arm 403 can be moved relative to the base 401 by releasing the clamp 402 so that the ambient light bracket 100 can be removed from the carrier 300.
[0051] See Figure 1 and Figure 4 The second positioning connection structure 310 on the top surface of the carrier 300 can be configured according to the specific situation of the first positioning connection structure 110 of the ambient light bracket 100. For example, in Figure 1 In the exemplary embodiment, the first positioning connection structure 110 includes one positioning post 102 and six riveting posts 101. Therefore, the top surface of the carrier 300 has one positioning hole 301 and six square holes 302. When the ambient light bracket 100 is installed onto the carrier 300, the positioning post 102 is inserted into the positioning hole 301, and the riveting posts 101 are inserted into the square holes 302. To improve the installation accuracy of the ambient light bracket 100 on the carrier 300, the second positioning connection structure 310 may include a boss 303. For example... Figure 4 As shown, the positioning hole 301 can be set as a round hole, and the boss 303 can be set around the square hole 302.
[0052] See Figure 3 In some embodiments, at least one side of the platform 220 may be provided with a handle 210, which facilitates moving the platform 220. Figure 3 In the exemplary embodiment shown, there are two handles 210, located on opposite sides of the platform 220. Of course, in other embodiments, the number and position of the handles 210 can be flexibly set as needed; for example, the handles 210 can be placed on the surface of the platform 220.
[0053] In some embodiments, the side of the platform 220 facing away from the tabletop may be provided with multiple legs 230, which facilitate the stable placement of the platform 220 onto a support surface such as a tabletop or the ground. To reduce the overall volume of the base 200, the length of the legs 230 can be approximately equal to the thickness of the platform 220. The tabletop of the platform 220 may be provided with some first mounting holes 221 for detachable and fixed connection with other components, so as to change the combination as needed and adapt to the testing of different ambient light brackets 100. Figure 4Taking the carrier 300 as an example, the second mounting hole 305 of the carrier 300 corresponds to some of the first mounting holes 221 on the platform 220. The carrier 300 can be installed onto the platform 220 by bolts, thereby meeting the testing requirements. Figure 1 As shown in the ambient light bracket 100, when it is necessary to test another type of ambient light bracket 100, the carrier 300 can be removed from the platform 220 and replaced with a carrier 300 of a different structure, so as to test the aforementioned other type of ambient light bracket 100.
[0054] See Figure 2 and Figure 6 In some embodiments, the positioning body may include an overlapping surface (not marked in the figure) perpendicular to the second facade 641, the overlapping surface being used to overlap with the side of the top surface of the carrier 300 away from the second region, representing a first region. Figure 6 As shown, the overlapping surface is a stepped surface formed below the second facade 641. When the positioning body is in the fallen state, the overlapping surface overlaps the edge of the carrier 300, so that the positioning body can better maintain its working position.
