Adjustable pressing ring torque fastening device and method

Abstract

The invention belongs to the field of optical element assembly and precision measurement, particularly relates to an adjustable pressing ring torque fastening device and method, and solves the technical problems that the pressing ring fastening torque cannot be quantified, the production cost is high and the assembly efficiency is reduced in the prior art. The adjustable pressing ring torque fastening device comprises a wrench lever, force arms, a fastener and a digital display instrument, the upper end of the torque sensor is fixedly connected with an adapter sleeve, and the lower end of thetorque sensor is fixedly connected with a chuck; the two force arms are parallel to each other, perpendicular to the wrench lever and connected with the wrench lever through the adapter sleeve, and atleast one force arm can move in a reciprocating mode in the length direction of the wrench lever and can be fixed to the wrench lever through the fastener; and the signal output end of each torque sensor is connected with the digital display instrument, and the end parts of the chucks in the two force arms are matched with a groove structure of a pressing ring to be fastened in shape. The distance can be adjusted and the chucks can be replaced according to different lens frames and pressing ring sizes, and the device can be widely applied to the pressing ring assembly process of optical lenses with different calibers.

Description

technical field [0001] The invention belongs to the field of optical element assembly and precision measurement, and in particular relates to an adjustable pressure ring torque fastening device and method. Background technique [0002] In the process of designing and assembling optical lenses, the axial fastening and positioning of optical elements is mostly carried out by tightening the pressure ring. Therefore, the fastening and positioning of the pressure ring is one of the important processes in the assembly of optical lenses. [0003] At present, tweezers and other general-purpose clamping ring fastening tools are mostly used for clamping ring fastening. The tightening degree of the clamping ring mainly depends on the experience and feel of the operator during use, and the tightening torque cannot be quantified. The applicability is not strong, and it is easy to cause The deformation of the mirror surface is difficult to meet the design requirements, and multiple disass...
