Abstract

The invention discloses a special torque screwdriver connector for assembly of an optical system. The special torque screwdriver connector comprises a bracket, a two-way screw rod, two clamping ring claw heads and two limiting blocks, wherein the bracket comprises a cross rod and the two-way screw rod parallel to the cross rod; threads I and threads II are formed in the two-way screw rod; the threads I and the threads II are the same in thread pitch and opposite in direction; two holes are formed in each of the two clamping ring claw heads; the two ends of the cross rod and the two-way screw rod penetrate through two holes in each clamping ring claw head; the two-way screw rod is in threaded connection with the clamping ring claw heads; the two ends of the cross rod are fixedly connected with the limiting blocks; the two ends of the two-way screw rod are in clearance fit with the limiting blocks; the two-way screw rod is capable of rotating around the own central axis; and if the two-way screw rod rotates around the own central axis, the distance between the two clamping ring claw heads is increased or reduced. The special torque screwdriver connector provided by the invention is simple in structure, convenient for part processing, and simple, convenient, stable and firm in assembly, and can be suitable for assembly of clamping rings of different apertures since the distance between the two clamping ring claw head is adjustable.

Description

technical field [0001] The invention relates to the field of special torque screwdriver joints for optical system assembly, in particular to the field of small precision transmission optical system assembly. Background technique [0002] A transmissive optical system usually consists of several optical lenses. The optical lens can be a positive lens or a negative lens. When designing and assembling the optical system, it is necessary to ensure the accuracy and stability of the optical lens, especially the precision optical system. There are more stringent requirements for the type, that is, when assembling, it is necessary to ensure that the force when fixing the lens is not too large, resulting in excessive changes in the lens surface type. [0003] At present, the optical lens in the precision transmission optical system is generally fixed by the pressing ring method. The pressing ring is in direct or indirect contact with the surface of the optical lens, and the pressing ...
