[0001] This utility model relates to the field of adjusting bolt technology, and in particular to a taillight adjusting bolt and an adjusting stroke testing device. Background Technology

[0002] As cars become increasingly common, people are paying more attention to their appearance in addition to performance when buying a car. In particular, they are paying more attention to the assembly details between components, no longer satisfied with just functionality, but demanding higher aesthetic standards.

[0003] Take taillights as an example. As one of the important exterior components of a car, different manufacturers in the industry have developed a variety of taillight shapes to improve the overall appearance of the vehicle and attract consumers.

[0004] Currently, the industry generally uses a through-hole mounting method for taillight installation. However, due to the numerous components involved in a vehicle, each component is often manufactured independently and then assembled. Inevitably, errors will occur in these processes. Ultimately, these errors accumulate, inevitably leading to poor matching between the taillights and the surrounding body panels, resulting in an unsatisfactory overall appearance and potentially lower customer satisfaction. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0033] This utility model provides a taillight adjustment bolt. Please refer to [link / reference]. Figure 1 and Figure 2 The outer circumference of the adjusting bolt is provided with an assembly thread 10, which is connected to the threaded inner hole of the taillight through the assembly thread 10. One end face of the adjusting bolt is an abutment surface 20, which is in direct contact with the body sheet metal; the other end face is provided with an adjusting groove 30. By inserting an adjusting tool into the adjusting groove 30, the adjusting bolt is rotated to move along the axis, and the distance between the taillight and the body sheet metal is adjusted by the abutment surface 20 that is in direct contact with the body sheet metal.

[0034] Specifically, the abutment surface 20 has an internal hexagon countersunk hole 40 in the middle, and the adjusting bolt is installed in the threaded inner hole of the taillight by using an internal hexagon wrench.

[0035] Furthermore, the sidewall of the adjustment groove 30 is evenly provided with at least two arc-shaped notches 50 around the central axis, and the adjustment bolt is driven to rotate by an adjustment tool that is compatible with the arc-shaped notches 50.

[0036] In this embodiment, the assembly thread uses an intermittent thread. This intermittent thread retains an effective thread segment, which can meet the design requirements of automotive lightweighting, and can achieve quick assembly and disassembly without easily getting stuck.

[0037] This utility model also provides a device for testing the adjustment stroke of a taillight adjusting bolt, such as... Figure 3-5 As shown, the device includes a frame 1 and a testing fixture 2. A testing rod 3 is provided on the top of the testing fixture 2. One end of the testing rod 3 is a testing head 4 for installing a taillight adjustment bolt. The other end is connected to a testing motor 5, which drives the taillight adjustment bolt to rotate. A lifting cylinder 6 is also provided on one side of the testing motor 5. The piston rod of the lifting cylinder 6 is connected to the testing motor 5 through a connecting rod 7, which drives the taillight adjustment bolt installed on the testing head 4 to move closer to or away from the testing fixture 2. A threaded sleeve 9 is detachably installed in the testing fixture 2. The threaded sleeve 9 matches the threaded inner hole of the taillight.

[0038] Specifically, a displacement sensor 8 is also provided on the frame 1. The sensing plate of the displacement sensor 8 is mounted on the test motor 5 to measure the adjustment stroke of the taillight adjustment bolt installed on the test head 4.

[0039] Furthermore, such as Figure 6 As shown, at least two arc-shaped protrusions 401 are evenly arranged on the side wall of the test head 4 around the central axis. The arc-shaped protrusions 401 are adapted to the arc-shaped notch 50 in the adjustment groove 30 of the adjustment bolt. When the test head 4 is inserted into the adjustment groove 30, it can drive the taillight adjustment bolt to rotate.

[0040] Furthermore, the test fixture 2 is provided with a test seat 201, and the threaded sleeve 9 is suspended in the test seat 201 along the axis, so that the taillight adjustment bolt enters the threaded sleeve 9 from above and then disengages from the threaded sleeve 9 from below, thereby testing the limit adjustment stroke of the taillight adjustment bolt.

[0041] Furthermore, a transverse cylinder 11 is provided on one side of the test fixture 2. The piston rod of the transverse cylinder 11 is connected to the test fixture 2 through the transverse plate 12 to drive the test fixture 2 to move laterally, thereby adjusting the center of the test fixture 2 to be consistent with the center of the test head 4, so as to be able to adapt to different specifications of taillight adjustment bolts for testing.

[0042] The testing process is as follows: First, the matching threaded sleeve 9 is aligned with the mounting groove and placed into the test seat 201, so that the threaded sleeve 9 is suspended in the test seat 201. Then, the taillight adjustment bolt to be tested is placed on the threaded sleeve 9. Then, the lifting cylinder 6 is started to drive the test head 4 downward until it is inserted into the adjustment groove 30 of the taillight adjustment bolt. Then, the test motor 5 is started, and the test rod 3 drives the test head 4 to rotate and move downward until the upper end face of the taillight adjustment bolt is flush with the upper end of the threaded sleeve 9. This is the initial position of the adjustment stroke, and the displacement sensor 8 records this initial position. Then, the test head 4 continues to rotate and move downward with the taillight adjustment bolt. It stops the moment the taillight adjustment bolt disengages from the threaded sleeve 9. This is the end position of the adjustment stroke, and the displacement sensor 8 records this end position. Finally, the optimal adjustment stroke range is defined based on the initial position and the end position recorded by the displacement sensor 8.

[0043] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
