Design and Experimental Study of Variable Freedom Bolt Clamping Mechanism

Abstract

Abstract:

A variable freedom bolt clamping mechanism was designed by the configuration design method of variable freedom mechanism, which could solve the problems of 20 bolt clamping positions for flange connection tool of underwater petroleum pipeline. The various functional structures in different working stages were analyzed, and the clamping mechanism had the function that clamping and release of the bolt group. The bolt clamping mechanism system's multi-body dynamics model was built by the software of ADAMS. By analysis of the operating process dynamics simulation, the stress curves of bolt were gained. The simulation results show that the group bolt forces uniform to meet the bolt clamping and positioning needs. The test of bolt clamping mechanism test prototype was carried on herein. The results indicate that the clamping mechanism has clamping and release function of the bolts, which will ensure the bolt positioning accuracy. The group bolts can lead-in the nuts successfully, which verifies that the design of the bolt clamping mechanism is rationality.

Key words: variable freedom mechanism;bolt clamping mechanism, structural design, ADAMS, dynamics simulation
