Abstract
The utility model is related to a kind of nut tightening devices, including pedestal, foundation bolt, nut spanner, adapting rod, torque multiplier, dial plate type torque spanner, pedestal is fixed on the ground by foundation bolt, part is installed on pedestal, torque multiplier is arranged in nut upper part to be removed, it is fixed on the base by torsional stop, riser, lower cross plate, the moment input end connection table dish-type torque spanner of torque multiplier, torque output end is fixedly connected with nut spanner by adapting rod, and the nut spanner coordinates with nut to be removed.The utility model is realized can meet high-torque using small torque, small space, major diameter nut being tightened and dismantling, it is ensured that it is safe to use, reduce it is unnecessary reprocess or replace new product caused by cost allowance, shorten the production cycle.
Description
Technical field
The present invention relates to a kind of device for screwing up, especially a kind of high-torque, major diameter nut tightening device.
Background technology
In the every profession and trade of industrial quarters, fastening and dismounting major diameter, high-torque nut are extremely difficult, especially in people
Member is difficult to construct, just more difficult using big specification torque wrench in the case that work-yard is limited to, and can not even grasp sometimes
Make.Major diameter, high-torque nut are tightened and dismantled, existing afterburner system is generally hydraulic actuation barrel structure to carry out
High-torque requirement is realized in reinforcing.But such structure operation get up it is very inconvenient, if carrying out frequent fractured operation, to behaviour
Author brings prodigious workload, working efficiency greatly to reduce, while the production cycle extends, and causes unnecessary resource wave
Take.
Invention content
The purpose of the present invention is to provide nut tightening devices, need high-torque that could carry out mainly for major diameter nut
The structure tightened and dismantled.Ensure during being tightened and dismantling nut, it is ensured that it is safe to use, improve working efficiency, section
About resource shortens the production cycle.
The purpose of the present invention is achieved through the following technical solutions：Nut tightening device includes pedestal, foundation bolt, positioning flower
Key, nut spanner, adapting rod, torque multiplier, dial plate type torque spanner, lower cross plate, riser, torsional stop, pedestal pass through lower margin
Bolt fixes on the ground, and part is installed on pedestal, wherein nut to be removed is located at part top, torque multiplier is set
It sets in nut upper part to be removed, is fixed on the base by torsional stop, riser, lower cross plate, the torque input of torque multiplier
Hold connection table dish-type torque spanner, torque output end to be fixedly connected with nut spanner by adapting rod, the nut spanner with wait for
Dismantle nut cooperation.
Riser is mounted on lower cross plate by the present invention by installing lower cross plate on pedestal, and anti-rotation is installed in riser upper end
Plate carrys out even twisting moment multiplier, to eliminate reaction force using torsional stop.Eventually by dial plate type torque spanner and torque times
Increase device connection to realize the output of torque, to reach using minimum working diameter, obtains the purpose of high-torque.Using torque
Multiplier is as main reinforcing mode, manual operation, without adding prodigious power to can be obtained larger torque；Using dial plate type torsion
Spanner can be operated, without very complicated extension bar and the device of very big structure.The present invention is realized using small torque, small space
High-torque can be met, major diameter nut being tightened and dismantling, it is ensured that it is safe to use, it reduces and unnecessary reprocess or replace
Cost allowance caused by new product, shortens the production cycle.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
As shown in Figure 1, nut tightening device includes pedestal 2, foundation bolt 1, positioning spline 13, nut spanner 8, adapting rod
11, torque multiplier 10, dial plate type torque spanner 12, lower cross plate 5, riser 6, torsional stop 7, pedestal 2 are fixed by foundation bolt
On the ground, it is installed with part 3 on pedestal 2, wherein nut to be removed 9 is located at 3 top of part, torque multiplier 10 is arranged
In 9 upper part of nut to be removed, it is fixed on pedestal 2 by torsional stop 7, riser 6, lower cross plate 5, the torque of torque multiplier 10
Input terminal connection table dish-type torque spanner 12, torque output end is fixedly connected with nut spanner 8, the nut by adapting rod 11
Spanner 8 coordinates with nut 9 to be removed.
