Abstract

The invention belongs to the technical field of automatic assembly, and discloses a circumferential bolt automatic pre-tightening and torque control device which comprises a posture position adjustingsupport and a plurality of sets of automatic wrench assemblies fixed to the posture position adjusting support. Each automatic wrench assembly comprises a screw head sleeve, a rotating shaft, a torque motor and a controller. The screw head sleeve is connected with the torque output end of the torque motor through the rotating shaft, and the torque motor is connected with the controller. The torque motor is fixed on the posture position adjusting support. The circumferential bolt automatic pre-tightening and torque control device can improve the operation efficiency and the operation precision.

Description

Technical field [0001] The invention relates to the technical field of automatic assembly, in particular to an automatic pre-tightening and torque control device for circumferential bolts. Background technique [0002] In the prior art, the pre-tightening and torque control operations of the bolts and nuts distributed on the circumference mainly include: manual multi-station sequential operation and multi-wrench synchronous operation. However, the manual multi-station sequential operation has high labor costs, is not conducive to batch flow operations, and is low in efficiency; multi-spanner synchronous operation is driven by a single-stage or two-stage transmission driven by the main gear or main pulley or main friction wheel at the same time. A wrench can drive multiple wrenches at the same time to improve work efficiency. However, it cannot accurately control the pre-tightening torque of a single bolt or nut. It can only achieve a unified torque output, which will cause the ac...
