Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.

As shown in fig. 1, the adjusting device for the stud nut comprises a stud tightening assembly 2 and a nut tightening assembly 3; wherein: the stud tightening assembly 2 comprises a driving cylinder 21, a first motor 22 positioned at the piston rod end of the driving cylinder 21 and a bit 23 positioned at the rotating shaft end of the first motor 22; the nut tightening assembly 3 comprises a second motor 31, a transmission assembly 32 positioned at the rotating shaft end of the second motor 31, a bearing 33 positioned at the driven end of the transmission assembly 32 and a tightening shaft 34 positioned on the bearing 33; the bit 23 extends through the bearing 33.

In this embodiment, first, the depth to which the stud needs to be screwed is set, the adjusting device is moved to a predetermined working position, the driving cylinder 21 is retracted, the first motor 22 is driven to press down the bit 23, meanwhile, the first motor 22 drives the bit 23 to rotate, so that the stud mounted on the bit 23 is screwed into the set depth, after the stud is screwed, the first motor 22 maintains potential energy and maintains torque, so that the stud is fixed, and then the second motor 31 drives the screwing shaft 34 to rotate through the transmission assembly 32, so as to realize screwing of the nut.

Further, in the present embodiment, the adjusting device further includes a base plate 1, and the stud bolt tightening assembly 2 and the nut bolt tightening assembly 3 are both located on the base plate 1.

Specifically, the first motor 22 is connected to a piston rod of the driving cylinder 21 through a connecting block.

Further, the transmission assembly 32 is connected with the second motor 31 through the speed reducer 4, and the existence of the speed reducer 4 can select a corresponding speed reduction ratio according to different tightening torques.
