3. 4. compressed spring of pressure sensor
The lower clutch of clutch 6. on 5.
7. 8. signal transmssion line of splined shaft
Fig. 1 is please referred to, Fig. 1 is a kind of structural schematic diagram of the real-time digital display device of internal combustion bolt wrench of the utility model.
A kind of real-time digital display device of internal combustion bolt wrench, the real-time digital display device of the internal combustion bolt wrench include display panel 1, signal
Transmission line 8, torsion adjust screwed retaining ring 2, pressure sensor 3, compressed spring 4, upper clutch 5, lower clutch 6 and splined shaft
7；Described 7 one end of splined shaft connects lower clutch 6；The lower clutch 6 is equipped with clutch 5；The upper clutch
One end of device 5 is equipped with compressed spring 4；One end of the compressed spring 4 is contacted with upper clutch 5, the other end and pressure sensing
Device 3 contacts；The outer end of the pressure sensor 3 is equipped with torsion and adjusts screwed retaining ring 2；The display panel 1 passes through signal
Transmission line 8 and pressure sensor 3 establish connection.
It should be understood that
The decrement that compressed spring 4 is adjusted in screwed retaining ring 2, the elastic force that compressed spring 4 generates are adjusted by rotary torsion
Directly act on pressure sensor 3 and upper clutch 5.Lower clutch 6 is rotated by engine driving, when above and below from
When clutch 6 is in normal meshing state, lower clutch 6 drives upper 5 synchronous rotary of clutch, and 4 pressure of compressed spring then passes through upper
Clutch 5 acts on the lower clutch 6 of rotation, to realize that 4 pressure of compressed spring is converted into the rotation torque of lower clutch 6.
The torque is exported through splined shaft 7 to bolt or nut, be finally completed bolt pair tighten and loose unloading.
In the working condition that progress nut is tightened (rotating forward of splined shaft 7), if required torque is no more than compressed spring 4
Provided by pressure when peak torque, upper and lower clutch 6 is in contact condition, and compressed spring pressure is continuously by clutch
Splined shaft 7 provides required torque, progress working properly, and nut will be tightened.And the torque needed for work is pressed greater than compressed spring 4
When the peak torque that power can be provided, upper clutch 5 is by upward compressed spring 4, so as to cause the disengaging of upper and lower clutch 6.When from
After clutch is detached from, upper clutch 5 no longer will keep synchronous rotary with lower clutch 6, cannot achieve and turn the pressure of compressed spring 4
The rotation torque of lower clutch 6 is turned to, at this point, the output services torque of splined shaft 7 is almost nil, is unable to complete twisting for bolt
Tightly.
In the loose unloading work for carrying out nut (reversion of splined shaft 7), due to the engaging structure of clutch, upper and lower clutch 6
It will remain contact, splined shaft 7 continues output services torque.
The peak torque that compressed spring 4 can be provided can adjust screwed retaining ring 2 by torsion and be adjusted.Nut is tightened, is increased
Add the decrement of compressed spring 4, compressed spring 4 generates bigger pressure, and then is capable of providing bigger torque.Conversely, unscrewing
Nut, 4 decrement of compressed spring will reduce, and the pressure generated becomes smaller therewith, and the peak torque that can be provided will also reduce.
A kind of real-time digital display device of internal combustion bolt wrench of the utility model can intuitively show rotation torque and compression bullet
Spring force size and adjustable, structure is simple, easy to operate；Equipped with control panel and pressure sensor 3, display panel 1 can be read
The signal of pressure sensor 3, and a series of processing are carried out to signal, display panel 1 is so as to the work of intuitive and real-time display
4 pressure of torque and compressed spring；Screwed retaining ring 2 is adjusted equipped with torsion, the adjustable compression of screwed retaining ring 2 is adjusted by rotary torsion
The decrement of spring 4, so that it is adjustable to realize rotation torque；Equipped with compressed spring 4, the elastic force generated by compressed spring 4 is straight
It connects and acts on pressure sensor 3 and upper clutch 5, to complete the conversion of rotation torque, structure is simple, occupies little space, and grasps
Facilitate；In the working condition that progress nut is tightened, according to peak torque provided by 4 pressure of required torque and compressed spring
Between relative size, can be realized and automatically control bolt and tighten；In the loose unloading work for carrying out nut (reversion of splined shaft 7),
Due to the engaging structure of clutch, upper and lower clutch 6 will remain contact, and splined shaft 7 continues output services torque, so that
Convenient disassembly.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvement and supplement without departing from the principle of this utility model, these are improved and supplement
Also it should be regarded as the protection scope of the utility model.
