Guide blocks are fixed at the upper and lower positions of the threaded block. A fixed block is fixed to the outside of the guide block. A connecting plate is installed at the front end of the fixed block. A fixing plate is fixed at a position near the top of the front end of the connecting plate. An electric telescopic rod is installed at the bottom end of the fixing plate. The bottom end of the electric telescopic rod is connected to an assembly plate. A slider is fixed to the back end of the assembly plate. Sliding grooves are provided on both sides of the front end of the connecting plate. An adapter plate is fixed at a position near the bottom of the back end of the connecting plate. A protective plate is fixed at a position near the bottom of the front end of the adapter plate.

The guide rails are installed at the upper and lower positions inside the adjustment grooves, and the guide blocks are installed at the upper and lower positions on the side of the adjustment column.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The adjustment mechanism of the 3D line scan camera of this optical detection device not only improves the adjustment ability, but also simultaneously improves the moving protection ability and operability of the adjustment mechanism;
[0014] (1) By assembling the connecting plate at the lower position on the back end of the connecting board and strengthening it with bolts, and then welding the protective plate at the lower position on the front end of the connecting plate. A circular groove is opened in the protective plate, and the protective ring is adhesively installed using the adhesive layer. In this way, the protective plate and the protective ring form a certain restrictive protection. At the same time, after the servo motor works, it drives the threaded rod to rotate. At this time, the threaded rod and the threaded block cooperate with each other to form a certain linear motion, which is guided by the cooperation of the guide block and the guide groove, and the upper and lower two guide blocks are respectively connected to the two fixed blocks. Therefore, the connecting board can be adjusted horizontally. At the same time, after the electric telescopic rod works, it can push the slider at the back end of the assembly board to move along the sliding groove. Therefore, during the working process, the up and down adjustment of the 3D line scan camera is formed, thereby better improving the overall adjustment ability during the working process;
[0015] (2) By opening the adjustment groove at the position on the side of the guide groove inside the adjustment box. When the guide block moves and reaches the side position inside the guide groove, the guide block will contact the buffer pad to form buffer protection. At the same time, the buffer spring is correspondingly compressed, and the adjustment column moves inside the adjustment groove. Therefore, the overall moving protection ability is better improved during the working process;
[0016] (3) By opening the guide groove at the upper and lower positions inside the adjustment box. Therefore, the connection installation with the guide block is completed by the up and down distribution of the fixed blocks. Therefore, a gap is formed between the connecting board and the adjustment box, thereby reducing the wear phenomenon caused by direct movement during the working process. And the D line scan camera can be adjusted left, right, up and down, improving the overall operability. BRIEF DESCRIPTION OF THE DRAWINGS
