The spline shaft includes a driving portion and a fixing portion, and the driving portion penetrating through the fixing portion is sleeved outside the square-headed driving shaft. The torque translation system is characterized in that the torque translation system comprises a gear case and a gear transmission mechanism arranged inside the gear case, a spline through hole matching with the fixing portion of the spline shaft is arranged on an upper cover of the gear case, a square hole matching with the square-headed driving shaft is arranged in the center of a driving gear in the gear transmission mechanism, and a driven square-headed driving shaft projecting out of the center of a driven gear of the gear transmission mechanism is parallel to the square-headed driving shaft of the torque drawing machine and matches with the nut sleeve.
Description
Technical field
The utility model relates to a kind of aid that is used for bolted.
Background technology
The various kinds of equipment majority of modern industry all is to be connected to main connected mode with bolt, and bolt connects with the equipment security of operation whether vital relation is arranged.The big more needed fastening power of bolt specification is big more, thus people generally to adopt power tool to carry out to the bolt of big specification now fastening.Common power tool has moment of torsion stretching-machine and pneumatic tools.And the moment of torsion stretching-machine be because can provide continuous, stable output pressure by hydraulic pump by the output pressure of pressure regulation hydraulic coupling, thereby becomes strict bolted first-selected fastening method.
The liquid medium (being generally hydraulic oil) that the operation principle of moment of torsion stretching-machine is generally high pressure or super-pressure promotes the interior piston rod acting of moment of torsion stretching-machine cylinder body, the piston rod of moment of torsion stretching-machine connects a ratchet mechanism, ratchet mechanism is by the square toes driving shaft of a standard of spline transmission, the square toes driving shaft is connected with hex nut by the sleeve of standard again, thereby realizes the rotating nut fastening bolt.
The position that bolt is present in the equipment is various, when up and down the space is restricted the residing position of bolt, common fastening facility can't put into from top carry out fastening.
The moment of torsion stretching-machine when work because of there being the outside reaction arm of force, according to Newton's third law, be equivalent to outside reaction force fulcrum and whole moment of torsion stretching-machine system produced inverting action by sleeve and nut, make the bolt end be subjected to extra unbalance loading moment, make the nuts and bolt thread of original normal engaged produce unbalance loading, thereby cause frictional contact surface to change, original face-face contact friction is changed into a little-face contact or line-face contact friction, cause frictional force to change.
Because each bolt need be adjusted the fulcrum of the reaction arm of force to obtain firm outside fulcrum when fastening, so the fulcrum of outside all is not quite similar during fastening each bolt, the offset loading force difference that counter-force fulcrum difference causes the counter-force fulcrum to produce, and then the frictional force difference that need overcome when causing each bolted, finally cause the bolt pretightening error of each bolt on the same flange face after fastening the finishing bigger.Distance between reaction force fulcrum and just fastening bolt is short more, and offset loading force is big more.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of can be fastening the limited bolt in locus up and down, and the moment of torsion stretching-machine can not produce the moment of torsion translation system of any unbalance loading when fastening bolt.
For realizing described purpose, moment of torsion translation system of the present utility model, be used with moment of torsion stretching-machine and ut socket, this moment of torsion stretching-machine comprises the square toes driving shaft of splined shaft and output torque, splined shaft comprises active part and standing part, active part passes standing part and is set in outside the square toes driving shaft, be characterized in, described moment of torsion translation system comprises gear-box and is arranged on the interior gear drive of gear-box, cover on the gear-box be provided with one with the suitable spline through hole of the standing part of described splined shaft, the driving gear center of gear drive has the square hole that matches with the square toes driving shaft, the driven gear center of gear drive is protruding with driven square toes driving shaft, this driven square toes driving shaft is parallel with the square toes driving shaft of this moment of torsion stretching-machine, and matches with described ut socket.
Described moment of torsion translation system, its further characteristics are that gear drive is meshing with each other by a driving gear and a driven gear and constitutes.
Described moment of torsion translation system, its further characteristics are that described driven square toes driving shaft is the hexagonal driving shaft.
Described moment of torsion translation system, its further characteristics are that described gear-box is made of with four screw lock closures upper box lid and following case lid; Driving gear and driven gear combine with gear-box partly respectively a copper bush.
After adopting technique scheme, the reaction force that produces in the fastening process is delivered on the gear-box by the standing part of splined shaft and the cooperation of spline through hole, there is not unbalance loading during bolted, the moment of torsion of moment of torsion stretching-machine output is converted into the rotation of nut more expeditiously, makes bolt obtain pure axial stretching.
Description of drawings
Fig. 1 is that the master of moment of torsion translation system of the present utility model looks cutaway view.
Fig. 2 is the vertical view of moment of torsion translation system.
Fig. 3 is the mated condition figure of moment of torsion translation system and moment of torsion stretching-machine.
Fig. 4 is the user mode figure of moment of torsion translation system.
The specific embodiment
As depicted in figs. 1 and 2, the moment of torsion translation system comprises gear-box 1 and the gear drive 3 that is arranged in the gear-box 1.The case lid of gear-box 1 is provided with the spline through hole 10 of suitable with splined shaft (can spline be connected).
Moment of torsion translation system and moment of torsion stretching-machine are used, the moment of torsion stretching-machine have as shown in Figure 3 splined shaft and the square toes driving shaft 312 of output torque, splined shaft has rotating part 310 and standing part 311, rotating part 310 passes standing part 311 and is connected with square toes driving shaft 312, square toes driving shaft 312 is inserted in the square hole at driving gear center of gear drive 3, the protruding driven square toes driving shaft in the driven gear of gear drive 3 or power output gear center is hexagonal driving shaft 4 in other words, these square toes driving shaft 4 attaching nut's sleeves 5.During work, the torsion of moment of torsion stretching-machine square toes driving shaft 312 outputs is delivered to driven square toes driving shaft or the hexagonal driving shaft 4 that parallels with it by gear drive 3.
The position that bolt is present in the equipment is various, when the space is restricted about the residing position of bolt, common fastening facility can't put into from top carry out fastening, moment of torsion translation system of the present utility model, with the moment of torsion of moment of torsion stretching-machine output never confined spaces move to confined spaces, thereby can address these problems.
As shown in Figure 4, moment of torsion stretching-machine 6 when work when having the outside reaction arm of force, make the reaction force that produces in the fastening process transfer to gear-box by the cooperation of splined shaft and spline axis hole, bolted does not have unbalance loading, the moment of torsion of moment of torsion stretching-machine output is converted into the rotation of nut more expeditiously, makes bolt obtain pure axial stretching.
