Synchronous tightening device and method for fuel tank drawstring bolts

Abstract

The invention discloses a synchronous tightening device and method for fuel tank drawstring bolts. The device comprises a moving part, a lifting part, a tightening part and a remote control lifting button, wherein the lifting part is fixed to the lower portion of the moving part, the tightening part is fixed to the lower portion of the lifting part, the remote control lifting button is installed on the tightening part, and the lifting part is electrically connected with the remote control lifting button. Through cooperative arrangement of the moving part, the lifting part, the tightening part and the remote control lifting button, synchronous tightening of a fuel tank drawstring can be achieved, compared with traditional sequential tightening of a single bolt, the working efficiency is greatly improved, labor is saved, the tightening force of bolts at the two positions of the fuel tank drawstring is the same in the synchronous tightening process of the fuel tank drawstring, and deformation caused by asynchronous tightening is avoided, so that the tightening firmness is not influenced.

Description

technical field [0001] The invention belongs to the technical field of fuel tank straps, and in particular relates to a device and method for synchronously tightening fuel tank strap bolts. Background technique [0002] In the field of heavy-duty trucks, the fuel tank is fixed on the fuel tank bracket through the fuel tank strap. Because of the large load capacity of the heavy-duty truck fuel tank, it is generally designed as a multi-tank bracket. [0003] At present, during the tightening process of the fuel tank tie, the worker generally tightens the tie bolt at one end first, and then tightens the tie bolt at the other end. During the process, serious assembly stress is generated due to asynchronous deformation, which affects the firmness of the tightening. On the other hand, when tightening the multi-tank bracket, workers need to tighten it repeatedly, which not only requires high work intensity, time-consuming, and The efficiency is low, and the installation accuracy i...

Problems solved by technology

[0003]At present, during the tightening process of the fuel tank strap, the worker generally tightens the strap bolt at one end first, and then tightens the strap bolt at the other end. The process of asynchronous tightening, on the one hand, causes serious assembly stress due to asynchronous deformation of the fuel tank during the tightening and fixing process, which affects the firmness of the tightening; , Repeated tightening, not only the work intensity is high, time-consuming, and work efficiency is low, but also the installation accuracy is low, and there are certain safety hazards, resulting in more after-sales claims
