Technical Field

[0001] This utility model belongs to the field of photoelectric measuring instrument technology, and specifically relates to a virtual image photoelectric measuring instrument. Background Art

[0002] With the rapid development and widespread application of the combination of microcomputer technology and optoelectronic technology, high-precision and high-stability instruments are needed to meet the high standards of modern production and research applications, especially in measurement applications.

[0003] A search revealed Chinese Patent Publication No. CN212963383U, which discloses a virtual image photoelectric measuring instrument. The instrument includes a detection platform fixedly mounted on the upper surface of a housing. A connecting frame is fixedly mounted on the upper surface of the detection platform. Each of the four end faces of the connecting frame is provided with a limiting groove. Two limiting grooves are arranged in pairs, and there are two sets of limiting grooves. Each set of limiting grooves has two movably connected transverse support rods. The instrument involves attaching both ends of a plate-shaped material to the upper surfaces of two right-angle support seats. The positions of the other two right-angle support seats are adjusted by moving the other two transverse or vertical support rods, and then connecting and attaching them to the plate-shaped material. A locking pin engages with the ends of the transverse and vertical support rods to lock and fix them in place.

[0004] However, the aforementioned virtual image photoelectric measuring instrument is only suitable for clamping products with regular shapes, such as sheet metal, and lacks a clamping structure that can accommodate various product sizes and structures. Furthermore, the detector at the bottom of the electrical enclosure is in a fixed position, making it impossible to inspect all four sides of the workpiece. Summary of the Invention

Utilizing an adjustable clamping structure, it accommodates products of different sizes and structures, ensuring accuracy during measurement. The lifting and horizontal movement structures, combined with vertical and horizontal detection heads, make this device suitable for comprehensive inspection of parts of different sizes and shapes, providing convenience for inspection personnel. A rotary motor drives the measuring table to rotate, facilitating vertical inspection of all four sides of the part.
