Fixed torque light round nut screw assembly and disassembly
We have a small round nut in the production of assembly and disassembly is very difficult, the nut itself is not large (see Figure 1), the wall thickness is thin, the surface roughness requirements are low, no scratches, deformation, and nut assembly The torque requirement is a fixed value. In view of the above circumstances and requirements, we have designed a set of special fixtures (Figure 2) to solve the above problems. The clamp is very convenient to operate, as long as the elastic clip 2 of the clamp is placed on the round nut, and then the outer sleeve 1 is twisted by a torque wrench. At this time, the outer sleeve 1 and the ring 3 are rotated, and the roller 4 is also in the gap. Scrolling in. Since the center of the three circular arcs of the ring 3 is not at the same point as the center of the elastic clip 2, the gap between them is not equal. When the ring 3 is rotated, the roller 4 is subjected to the elastic clamp 2 and
