Embodiment Construction

[0026] The core of the present invention is to provide a synchronous wrench, which can quickly realize the disassembly and assembly of bolts, and simultaneously disassemble and assemble diagonal bolts synchronously, thereby improving the uniformity of fastening force.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Please refer to figure 1 with figure 2 , the embodiment of the present invention provides a synchronous wrench, including a fixing frame 5 , a driving motor 4 , and at least two bolt t...

Abstract

The invention discloses a synchronous wrench which comprises a fixed frame, two drive motors installed on the fixed frame, two bolt screwing components which are in transmission connection with rotary shafts of the two drive motors in a one-to-one correspondence manner and are used for disassembling two bolts which are in opposite corners and a control device which is in control connection with the drive motors. When the synchronous wrench works, the two bolt screwing components are matched with the two bolts in the opposite corners respectively, the control device controls the two drive motors to synchronously rotate, and thus the two bolt screwing components are driven to synchronously rotate, and synchronous mounting or disassembly of the two bolts in the opposite corners is realized. Compared with the existing manner of manually disassembling bolts one by one, by adopting the synchronous wrench, the two bolts in the opposite corners can be automatically and synchronously mounted once, so that the working efficiency is improved; and meanwhile, the two bolts in the opposite corners can be synchronously mounted and disassembled, so that the stress applied to the opposite corners in which the two bolts are located is uniform, and the sealing performance to a flange in the nuclear power industry can be improved.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to a synchronous wrench. Background technique [0002] Bolts are indispensable fastening parts in industrial engineering, and bolts are usually disassembled with a wrench. For some equipment that is fastened by multiple bolts, the bolts need to be quickly disassembled. Take the installation and disassembly of flanges in nuclear power and other professional projects as an example. The rapid installation and disassembly of flange equipment can reduce the risk of human body. The residence time in the environment. Manually installing and dismounting the bolts on the flange one by one is not conducive to reducing working time and improving work efficiency, and it is easy to cause uneven stress on the diagonal bolts on the flange when the flange is installed, resulting in Sealing performance is reduced. [0003] To sum up, how to solve the problems of low work ef...
