Problems solved by technology

Since both the bolt connection and the stud bolt connection must be composed of bolts and nuts, and the bolts and nuts are detachable and independent parts, so they need to be fixed at one end and loosen at the other end during use, which has caused a large number of bolts to be used. The time-consuming and labor-intensive characteristics of the connection project
At the same time, since the bolt connection in engineering and real life is completed by manual tightening, it is impossible to ensure that the tightness of each bolt is consistent, which will affect the stiffness of the engineering structure. Therefore, it is necessary to invent an efficient bolt connection component. Advanced automatic tensioning device, further improving engineering safety on the basis of saving manpower

Embodiment 1

[0030] Such as Figure 1~3 As shown, an automatic tightening device for bolted components, the bolted components include bolts and nuts screwed on the bolts, which include:

[0031] Signal analysis and processing module 1;

[0032] A nut fixing plate 2 for fixing nuts;

[0033] Bolt screwing device, the bolt screwing device includes a bolt fixture 4 for fixing the head of the bolt, a rotary drive device 10 and a variable voltage power supply device 5, the rotary drive device 10 is connected to the bolt fixture 4, In order to drive the bolt fixture 4 to rotate by the rotary drive device 10, the variable voltage power supply device 5 is connected to the rotary drive device 10 so as to adjust the output torque value of the rotary drive device 10 to the bolt fixture 4 through the variable voltage power supply device 5;

[0034] Strain collection plectrum 6, the strain collection plectrum 6 is in contact with the bolt fixture 4, so that the strain collection plectrum 6 is moved b...

Embodiment 2

[0044] A working method for an automatic tightening device for bolted components as described in Embodiment 1, the steps of the method include:

[0045] (1) Fix the nut on the nut fixing plate 2, and fix the bolt on the bolt fixture 4;

[0046] (2) During the process of the rotation driving device 10 driving the bolt fixing part 4 to rotate to tighten the bolt, the rotating driving device 10 continues to increase the torque value output to the bolt fixing part 4 under the action of the variable voltage power supply device 5, and at the same time the strain signal The collection device 7 collects the strain signal of the strain collection plectrum 6 from time to time and feeds it back to the signal analysis and processing module 1 for it to judge whether the strain collection plectrum 6 is in a static state or a toggle state. When the strain collection plectrum 6 is in a static state, The signal analysis and processing module 1 sends a stop toggling signal to the variable volta...

The automatic tightening device for the bolt connecting components comprises a signal analysis and processing module, a nut fixing plate, a bolt screwing device, a strain collection shifting plate and a strain signal collecting device, wherein the bolt screwing device comprises a bolt fixing piece for fixing the head part of a bolt, a rotation driving device and a transformation power supply device; the rotation driving device is connected with the bolt fixing piece; the transformation power supply device is connected with the rotation driving device; the strain collection shifting plate is in contact matching with the bolt fixing piece; a signal output end of the strain signal collecting device is connected with a signal input end of the signal analysis and processing module; and a signal output end of the signal analysis and processing module is connected with a signalinput end of the transformation power supply device. According to the automatic tightening device for the bolt connecting components, on the basis of saving manpower, the consistency of the tightnessof each bolt is ensured, and the safety of a project is improved.

Description

technical field [0001] The invention relates to an automatic tensioning device for bolted components and a working method thereof, belonging to the field of mechanical tools. Background technique [0002] At present, bolted connections are widely used in various projects. For example, in steel structure connections, bolted connections are second only to welded connections. In real life, bolted connections also play an irreplaceable role. Since both the bolt connection and the stud bolt connection must be composed of bolts and nuts, and the bolts and nuts are detachable and independent parts, so they need to be fixed at one end and loosen at the other end during use, which has caused a large number of bolts to be used. The connection project is time-consuming and labor-intensive. At the same time, since the bolt connection in engineering and real life is completed by manual tightening, it is impossible to ensure that the tightness of each bolt is consistent, which will affec...
