Technical Field

[0001] This utility model relates to the field of precision measurement equipment technology, and in particular to a precision measurement device for automotive retroreflectors. Background Technology

[0002] With the rapid development of the automotive industry, vehicle safety and exterior design are receiving increasing attention. As a crucial component ensuring driving safety, the performance and quality of automotive retroreflectors directly affect a vehicle's visibility at night or in low-visibility conditions.

[0003] Existing measuring devices typically employ cumbersome positioning methods to locate objects, resulting in poor object positioning accuracy. They cannot easily adapt to the object's position for adaptive clamping and limiting, leading to poor practicality. Furthermore, during long-term use, the workpiece is prone to slippage and other issues during later driving processes.

[0004] Therefore, it is necessary to provide a precision measuring device for automotive retroreflectors to solve the above-mentioned technical problems. Utility Model Content

The inner wall of the device frame is provided with a semi-transparent and semi-reflective mirror. The light-transmitting aperture is opened on the inner wall of the left end of the measuring structure. The transparent glass plate is installed on the right end of the measuring structure for observation during use.

[0009] Preferably, the horizontal drive assembly includes a first drive member, a drive slider slidably attached to the output end of the first drive member, a mounting frame on the top of the drive slider, and fastening plates installed at both ends of the bottom of the mounting frame for securing the position of the mounting frame.

[0010] Preferably, the angle driving assembly includes a second driving component and a fixed frame. The fixed frame has rotating rods at both ends. The inner wall of the second driving component has a transmission component for position transmission of the rotating rods. The inner walls of both ends of the fixed frame have concave positioning frames, and the inner wall of the rotating rods has convex positioning plates for angle adjustment of the fixed frame.

[0011] Preferably, the adaptive clamping assembly includes a drive motor, an output end of which is fitted with a bidirectional threaded rod, both ends of which are threadedly connected to movable sliders. An adjustment frame is provided at the bottom of the movable slider, and an adjustment groove is formed on the inner wall of the adjustment frame.

[0012] Compared with related technologies, this utility model has the following beneficial effects:

[0013] In order to ensure the stability of the measured object's position during use, this utility model uses an adaptive clamping component and a telescopic drive component to quickly and automatically adjust to accommodate objects of different sizes. This eliminates the need for operators to frequently change clamps or perform complex manual adjustments, reducing problems such as object deformation and shaking caused by improper clamping, thereby improving the accuracy and reliability of the measurement. At the same time, during use, the measuring device uses a combination of a horizontal drive component and an angle drive component to flexibly adjust the position of the object to be measured, and reduces workpiece position deviation and slippage during adjustment.
