This invention relates to the field of precision measurement technology, and more particularly to a precision mechanism alignment device. The precision mechanism alignment device includes a frame, an upper alignment mechanism, a lower alignment mechanism, and a coarse alignment mechanism. The lower alignment mechanism includes a first support, a roller
assembly, and a
micrometer adjustment
assembly. The first support is mounted on the frame, and the
micrometer adjustment
assembly is mounted on the first support and connected to the roller assembly. The
micrometer adjustment assembly is configured to adjust the horizontal level of the roller assembly in the height direction. The upper alignment mechanism includes a second support, a vision component, and a leveling bolt. The second support is slidably mounted on the frame in the height direction, and the vision component is mounted on the second support. The vision component is configured to detect the
horizontal angle of the second support. The leveling bolt is mounted at the bottom of the second support. The coarse alignment mechanism is mounted at the top of the first support. The leveling bolt can abut against the coarse alignment mechanism, enabling precise adjustment and reducing errors, thereby achieving accurate alignment and facilitating operation.
