Detailed Description
The invention is further described below with reference to the accompanying drawings.
A large-size electric nut system for quickly fastening and disassembling a flange comprises an electric nut 1, and is characterized by comprising a rotating system, a detection system and a data processing system; the rotating system is an electric rotating machine 6 arranged in the electric nut, and a crankshaft gear of the electric rotating machine 6 is connected with a rolling device 3 of the electric nut, so that a nut thread welded in a rotating ring is driven to rotate; the detection system comprises laser range finders 2 and 4 arranged on the surface of the nut and a sound wave transmitting and receiving device 5 arranged on the side surface of the nut; the data of the detection system is transmitted to a data processing system of an external control panel, and the rotating system acts according to an instruction sent by the data processing system.
Referring to fig. 1 and 2, the embodiment is illustrated, in fig. 2, 20 electric nuts are required to be installed to fasten bolts, each electric nut is screwed on the bolt according to the serial number, and the bolt fastening should be according to the principle of multi-step fastening and sequential fastening. After the installation is finished, press switch A, open electronic nut of A and rotate, divide into fastening bolt three times. The first time of electric nut rotation is 50% of the total preset torsion value, the torsion value is detected through current, the second time of electric nut rotation is 80% of the torsion value, and the third time of electric nut rotation is hundred percent of the torsion value. In the process of fastening the bolt, laser range finders at two ends of the electric nut are started to emit laser to irradiate the flange surface, and the distance from the electric nut to the flange surface is detected through the laser at the two ends to judge whether the electric nut is shifted into the bolt in a balanced manner. Taking 20 electric nuts as an example, the nut A starts to rotate, the sound wave emitter on the side surface of the electric nut starts to emit sound waves, and the bolt is forbidden to be fixed by selecting the fastening principle of two synchronous opposite sides, so that the opposite sides of the bolt A are the bolt K, and the bolt K starts to synchronously rotate after receiving the sound waves emitted by the bolt A. And other groups of bolts also fasten the bolts according to the principle of synchronously fastening two opposite sides.
