Description
Technical Field
[0001] The utility model relates to the detection application of automobile parts, in particular to a detection limit mechanism for automobile trim panels. Background Art
[0002] In automobile production and processing, automobile trim panels are one of the important components, such as the front cover trim panel, interior floor mat trim panel, roof trim panel, etc. These trim panels require relatively high dimensional accuracy to ensure that they can accurately match the pre-installed parts after installation on the car. In order to ensure assembly accuracy, the size and position accuracy of the contours, openings and other parts of the automobile trim panels need to be tested after production and processing.
[0003] Currently, the inspection of automotive trim panels primarily utilizes a test bench designed specifically for the panel's structure. The test bench is equipped with a clamp for quickly positioning the panel and a support frame conforming to the panel's contour. To prevent the panel from being positioned imprecisely on the test bench, the test bench is also equipped with locating posts that align vertically with the panel's holes. These locating posts are of a fixed height and have a positioning protrusion on their top. When the panel is placed on the test bench, its openings must be aligned with the pre-set protrusions on the top of the locating posts. However, due to the fixed height of existing locating posts, the panel must be lifted to a certain height and then aligned when placed on the test bench. After testing, when removing the panel from the test bench, the clamp must be released, and the panel must still be lifted to a certain height to separate from the top of the locating posts. This lifting process is often manual, which is inconvenient for larger panels, such as interior top panels and hood panels. Insufficient lifting height can easily cause interference between the panel's openings and the locating protrusions on the top of the locating posts, hindering assembly and disassembly of the panel on the test bench. Summary of the Invention

Figure 3 As shown, the guide hole on the guide sleeve 21 is plugged into the column 22 on the limit column 2, and the column 22 is vertically plugged into the guide sleeve 21 and slides up and down with the guide sleeve 21. The lower end of the column 22 passes through the guide connection hole and extends into the active cavity 14; in order to prevent the column 22 from axially rotating in the guide sleeve 21 and affecting use, refer to the appendix of the instruction manual. Figure 3 and 6 As shown, the front side of the column 22 is provided with a limit surface flush with the upper and lower sides along its height direction, and the limit surface constitutes a limit portion 222 for preventing the column 22 from axially rotating, which makes the cross section of the column 22 form a "D"-shaped structure. Further, in order to cooperate with the limit portion 222 on the column 22, the guide hole end surface structure on the guide sleeve 21 is consistent with the cross-sectional structure of the column 22; refer to the appendix of the specification. Figures 1 to 3 As shown, the front of the base 1 is provided with a front-to-back connected jack 12 near the bottom, and the jack 12 passes through the active cavity 14 from front to back. Figure 4 As shown, the front bottom of the jack 12 is provided with a guide portion 121, which is a downwardly inclined slope. The jack 12 is plugged with a push-pull rod 3 that can move forward and backward along it, and the push-pull rod 3 passes through the part of the column 22 located in the base 1. In order to facilitate the push-pull rod 3 to pass through the column 22, refer to the appendix of the instruction manual. Figure 3 and 6 As shown, the portion of the column 22 located in the active cavity 14 is provided with a slot 221 communicating front and back, and the slot 221 corresponds to the front and back of the insertion hole 12; Figure 3 and 6 As shown, the push-pull rod 3 is arranged in the corresponding front and rear jacks 12 and slots 221, and the guide portion 121 can reduce the obstruction of the front end of the active cavity 14 to the push-pull rod 3 when the push-pull rod 3 moves forward and backward; in order to utilize the front and rear movement of the push-pull rod 3 to drive the limit column 2 to move up and down, refer to the appendix of the manual Figure 3 and 5 The cam 32 is provided with a plurality of holes 32 on the top of the cam 32 so as to prevent the cam 32 from sliding out of the cam 32 and causing the cam 32 to slide downwards, thereby preventing the cam 32 from sliding out of the cam 32. Figure 5As shown, the portion of the rod body 31 between its front end and the center of the oblong hole 32 is the low portion 35, which is used to drive the limit column 2 downward so that the top height of the limit column 2 is at the lowest position. The portion of the rod body 31 between the rear end of the oblong hole 32 and the rear end of the rod body 31 is the high portion 33, which facilitates the limit column 2 to move upward so that the top height of the limit column 2 is at the highest position. It should be noted that the upper and lower heights of the low portion 35 are less than the upper and lower heights of the socket 12, which facilitates the push-pull rod 3 to move back and forth in the socket 12. The portion of the rod body 31 between the high portion 33 and the low portion 35 is the transition portion 34, which is an inclined surface connecting the high portion 33 and the low portion 35, which is convenient for the high portion The connection transition between 33 and the low-position part 35 does not cause any obstruction with the bottom of the slot hole 221. The height between the upper and lower parts of the low-position part 35 is at least twice the height between the upper and lower parts of the high-position part 33. The height between the top of the rod body 31 and the top of the slot hole 221 is not less than the height between the upper and lower parts of the low-position part 35, ensuring that the low-position part 35 of the rod body 31 can be inserted into the slot hole 221 along the pin rod 5. The downward stroke distance of the slot hole 221 is at least consistent with the height of the low-position part of the rod body 31, and no obstruction will be caused. In order to facilitate the pushing and pulling of the rod body 31, a ball head handle 36 is provided at the front end of the rod body 31. By driving the push-pull rod 3 to move back and forth and combining the upward tension of the limit column 2 by the spring 4, the limit column 2 can be lifted up and down.
[0031] The specific working principle is as follows: the push-pull rod 3 is manually driven by the ball handle 36 to move backward along the socket 12, and the transition portion 34 on the rod body 31 passes through the slot hole 221. The transition portion 34 presses the bottom of the slot hole 221 and drives the limit column 2 downward, and stops when the low portion 35 on the rod body 31 enters the slot hole 221 backward. At this time, the low portion 35 on the rod body 31 presses the push-pull rod 3 down to the lowest point, and its top drops to the lowest point. At this time, it is convenient to place the car trim on the car inspection table or to make the top head 24 of the limit column 2 drop and disengage The assembly hole of the automobile trim panel after inspection on the automobile inspection bench is convenient for disassembling the automobile trim panel from the automobile inspection bench; when the rod body 31 is pulled backward by the ball handle 36, the contact between the rod body 31 and the slot 221 is transferred from the low part 35 along the transition part 34 to the high part 35. Since the height of the high part 35 is smaller than the low part 35, under the action of the upward tension of the spring 4 on the limit column 2, the limit column 2 rises upward under the action of the spring 4, and can extend into the corresponding assembly hole on the automobile trim panel placed above it through the top head 24 thereof, so as to facilitate the limiting positioning of the automobile trim panel.
[0032] The automobile panel detection limiting mechanism drives the limiting column to move up and down through the push-pull rod, and the automobile panel placed on the automobile detection table can drive the limiting column to rise upward, so that the top head of the limiting column extends into the corresponding automobile panel assembly hole, so that the automobile panel is precisely positioned on the detection table, and the automobile panel does not need to be lifted to be connected with the top head, and when the automobile panel is disassembled from the automobile detection table, the top head only needs to be driven to be separated from the assembly hole of the automobile panel, so that the top head does not interfere with the automobile panel, and the automobile panel is convenient to take off from the detection table, so that the automobile panel is convenient to quickly install, position and disassemble on the automobile detection table, the operation is convenient, and the detection efficiency is improved.
[0033] It should be emphasized that the above are only the preferred embodiments of the present application, and are not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
