RETAINER ASSEMBLY TOOLS FOR LENS OPTICAL SYSTEM INCLUDE THE SPACING STRUCTURE

In an optical system including a cylinder and formed by mounting multiple lenses inside the cylinder, the present invention relates to a parallel jig for assembling a lens retainer of the optical system having a space adjusting structure which assembles and fixates the lenses composing the optical system with the ring-shaped retainer. A handle, a body, legs for rotating the retainer, and a bar for rotating the retainer are formed into an assembly type. The handle is joined to the upper side of a vertical rad connected to the central upper part of the body to be separated. A joining fixture for joining a torque wrench is formed on the upper part of the vertical rod. The legs for rotating the retainer are joined to both sides of the body to be slid, thereby being fixated by fixing bolts adjusting distance between the legs for rotating the retainer. The legs for rotating the retainer are joined by connecting a cylindrical vertical bar to a rectangular horizontal bar and one end of the rectangular vertical bar to be detached. The bar for rotating the retainer having predetermined length is mounted on the center of the lower part of the cylindrical vertical bar. Therefore, the present invention enables the retainer of which size is changed according to the diameter of the lens to be assembled or separated by one tool. The present invention primarily fixates the lenses by rotating the handle and then secondly fixates the lenses while fastening torque is controlled by joining the torque wrench, thereby accurately, simply, and rapidly fixating the lenses with set lens fixing-fastening torque.
