Synchronous wrench for bolts arranged in annular array

Abstract

The invention discloses a synchronous wrench for bolts arranged in an annular array mode. The synchronous wrench comprises a main body shell. According to the invention, a plurality of bolts can be rotated to bolt holes in which the bolts need to be mounted at the same time under the effect of synchronous rotation, therefore, the phenomena that due to the fact that a single bolt is stressed, the fastening angle of a connecting part deviates and the threads are damaged, the service life is short can be effectively prevented. The protection capability on the bolt structure is improved; potentialsafety hazard degree reduction, an annular array type longitudinal and transverse staggered rod body linkage mechanism is arranged; longitudinal and transverse cross arrangement is utilized; therefore, the transmission effect of rotation is realized; meanwhile, due to point contact and small friction force, longitudinal movement is not greatly affected, the efficiency is improved, and potential safety hazards in use are reduced; and in addition, the wrench is provided with an annular array spiral spring type maximum rotating strength control mechanism, and the phenomenon that a threaded structure is damaged due to the fact that the rotating strength is too large is avoided.

Description

technical field [0001] The invention relates to the technical field of drive devices, in particular to a synchronous wrench for setting bolts in an annular array. Background technique [0002] At present, the installation between the sealing cover and the cylinder body of large-scale equipment is fastened by bolts, and the common fastening method is to install bolts one by one, which will lead to the connection caused by the force of a single bolt. The deviation of the fastening angle of the parts and the occurrence of the phenomenon of lower life caused by the damage of the thread are more limited. Contents of the invention [0003] The object of the present invention is to provide a synchronous wrench for setting bolts in an annular array, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a synchronous wrench for setting bolts i...

Problems solved by technology

[0002] At present, the installation between the sealing cover and the cylinder body of large-scale equipment is fastened by bolts, and the common fastening method is to install bolts one by one, which will lead to the connection caused by the force of a single bolt. The deviation of the fastening angle of the components and the occurrence of the phenomenon of lower service life caused by thread damage have relatively large limitations.
