Digital display type pressing ring torque fastening device and method

Abstract

The invention belongs to the field of optical element assembly and precision measurement, and particularly relates to a digital display type pressing ring torque fastening device and method. The technical problem that in the prior art, the pressing ring fastening torque cannot be quantified, and consequently a mirror surface deforms is solved. The digital display type pressing ring torque fastening device comprises a torque sensor, an adapter sleeve, a torsion bar, a clamping jaw and a digital display instrument, wherein the torque sensor, the adapter sleeve and the torsion bar are sequentially and coaxially arranged in a sleeving manner and fixed; a clamping head is arranged at one end of the torsion bar, and the clamping jaw is detachably fixed to the clamping head; the clamping jaw comprises a horizontal arm and vertical arms positioned at the two ends of the horizontal arm, and the direction where the horizontal arm is positioned is perpendicular to the axial direction of the torsion bar; the ends of the two vertical arms are clamping tips, the distance between the two clamping tips is matched with the diameter of a to-be-fastened pressing ring, and the two clamping tips are used for being inserted in a groove of the to-be-fastened pressing ring; the digital display instrument is connected with the output of the torque sensor and used for displaying the output value of thetorque sensor; and a handle is arranged on the torque sensor, and the clamping jaw is driven to fasten the pressing ring by rotating the torque sensor through the handle.

Description

technical field [0001] The invention relates to the field of optical element assembly and precise measurement, in particular to a digital display type pressure ring torque fastening device. Background technique [0002] In the optical lens assembly process, pressure rings of different sizes are involved, which are mainly used for the axial fastening and positioning of optical lenses or components, and are one of the important processes in optical lens assembly. [0003] Most of the existing clamping ring tightening tools are mainly tweezers and other general clamping ring tightening wrenches. The disadvantage is that the degree of tightening of the clamping ring mainly depends on the experience and feel of the operator, and the tightening torque cannot be quantified. , it is easy to cause the mirror surface to deform and it is difficult to meet the design requirements, and the repeated disassembly and assembly can easily cause the mirror surface to be scratched, which affect...
