A dual-clamping variable-pitch rotary adapter for assembly tightening

Abstract

This utility model discloses a dual-clamping variable-pitch rotary adapter for assembly and tightening, including a support base, a rotating shaft fixedly mounted on the upper end of the support base, a mounting base fixedly mounted on the rotating shaft, and a fixing base fixedly mounted on the upper end of the support base away from the rotating shaft. The fixing base has two circular through slots that are connected left and right. This utility model fixes two modular clamps to two locking blocks respectively with positioning bolts and locking slots. The distance between the clamping blocks and the clamping base is adjusted by adjusting bolts, so that the two modular clamps can be assembled and connected in a dual-clamping position, improving assembly efficiency. By passing several limiting rods through the two circular through slots on the fixing base and positioning them with the locking blocks, the position of the limiting rods in the circular through slots is adjusted by turning the locking bolts on several circular holes. This allows the limiting rods to adjust the connection distance between the two modular clamps with the locking blocks, improving assembly applicability.

[0018] On the same side, locking blocks 7 are fixedly installed at the ends of the two limiting rods 6 away from the fixed base 4. Each locking block 7 is equipped with a modular clamp 8, which can be used to clamp tightening guns within a certain diameter range. Positioning bolts 12 are threaded through the sidewalls of both locking blocks 7 facing the support base 1, passing between the two limiting rods 6.
