Description
Technical field
The utility model relate to a kind of for bolt or nut, determine moment of torsion assembling determine torque sleeve barrel spanner.
Background technology
At present, known torque wrench has the types such as mechanical audible alarm formula and pointer dial type, wherein, apply more general mechanical audible alarm formula spanner by ratchet, compression spring, torsion locking joint, torsion is adjusted the formations such as screw, when arriving setting moment of torsion, moment of torsion there will be mechanical collision sound, if but exert oneself again, there will be the excessive phenomenon of torsion, this type of spanner also easily occurs that compression spring fatigue increases torque value error, the locking joint torque value that makes easy to wear cannot lock, ratchet is easy to wear makes the spanner situation such as cannot normally work, main cause is that the primary structure member of this type of spanner mostly is a little or line contact, its stress is concentrated, rapid wear.In addition, also easily there is torsion gage damage in pointer dial type spanner or error makes the situations such as torque value misregister.
In addition, known box spanner is comprised of annexes such as the sleeve of different size and handle, extension bar, ratchet spanneres, is not conventionally equipped with torque wrench, if need, uses, and will buy separately.
Summary of the invention
The purpose of this utility model is: in order to overcome traditional torque wrench stress, concentrate the shortcoming of rapid wear and the deficiency of conventional sleeve spanner configuration, the utility model provides a kind of torque sleeve barrel spanner of determining, this spanner coordinates traditional sleeve and handle capable of being realization to assemble the moment of torsion of determining of bolt, and working stability.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts: a kind ofly determine torque sleeve barrel spanner, axle sleeve, torsion adjusting nut, torsion adjustment block, stage clip, face gear driving link, face gear driven member, sleeve, feather key and internal circlip, consist of, its architectural feature is: the torsion adjusting nut that is threaded for outside metal axle sleeve left end; In axle sleeve, left end is provided with torsion adjustment block, torsion adjustment block is notch cuttype, at torsion adjustment block right-hand member, stage clip is set, immediately right-hand member connecting end surface gear driving link and the face gear driven member of stage clip, face gear driving link and face gear driven member mesh with gear; Torsion adjustment block axle side is provided with drag chain A and coordinates with the keyway of axle sleeve outer wall upper end, on face gear driving link axle, drag chain B is installed, and coordinates with the keyway of axle sleeve upper right side; In the middle of end-tooth driven member, the end face left side arranges internal circlip A, and the right arranges internal circlip B; Axle sleeve left end connects combination wrench or box spanner handle, and the face gear driven member other end square toes in axle sleeve right-hand member connect the sleeve of different size.In axle sleeve left end, have a square hole, axle sleeve is outward hexagon end face, is provided with keyway and torsion indicating graduation on axle sleeve outer wall.The end-tooth wheels of face gear driving link and face gear driven member are trapezoidal, are face contact between the flank of tooth.
Before work, turn torsion adjusting nut is in the moment of torsion scale value of indication, torsion adjusting nut by torsion adjustment block by the pressure-acting of stage clip in face gear driving link, also this pressure is passed to face gear driven member simultaneously, during work, the torsion that comes from pinch bar will act on face gear driving link by axle sleeve, Driving plane gear driven member thereupon, sleeve and bolt rotation, because being shaped as of end-tooth is trapezoidal, by frictional force, carry out work, when the eventually tight power of bolt arrives predetermined torque requirement, between end-tooth by relative sliding, and send sound, now, come from outside torsion and will no longer act on bolt, with this, reach the object of fixed-torsional moment assembled bolt.
The beneficial effects of the utility model are, after pre-set torque value, operator does not need to observe graduation indication again, just can judge whether bolts assemblies reaches determine torque demand by sound.Because end-tooth is trapezoidal, its contact-making surface is large, can effectively reduce the tired and wearing and tearing that long-term work produces, in addition, the utility model is practical right-handed thread both, be suitable for again left hand thread, it is simple in structure, and volume is small and exquisite, be convenient for carrying, can be used as the conventional annex of known box spanner, can effectively make up the deficiency of known box spanner annex, also reduced the cost of independent purchase torque wrench.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of determining torque sleeve barrel spanner of the present utility model.
Fig. 2 is the shaft side figure of this box spanner axle sleeve 1.
Fig. 3 is the shaft side figure of this box spanner torsion adjustment block 3, has two keyways that are arranged symmetrically with on it.
Fig. 4 is the shaft side figure of this end face of box wrench gear driving link 6, has two keyways that are arranged symmetrically with on it.

In figure, 1. axle sleeve, 2. torsion adjusting nut, 3. torsion adjustment block, 4. feather key A, 5. stage clip, 6. face gear driving link, 7. feather key B, 8. face gear driven member, 9. internal circlip A, 10. internal circlip B, 11. sleeves.
The specific embodiment
In Fig. 1, axle sleeve 1 is the torsion adjusting nut 2 that is threaded for outer left end, and torsion adjustment block 3, stage clip 5, face gear driving link 6 and face gear driven member 8 are installed in axle sleeve 1 from left to right.Torsion adjustment block 3 axle side symmetric positions are provided with feather key A4 and coordinate with the keyway on axle sleeve 1, torsion adjustment block 3 is multidiameter, right-hand member connects stage clip 5, the right-hand member connecting end surface gear driving link 6 of stage clip 5, meanwhile, axle sleeve 1 right-hand member is also provided with keyway, limits the circumferential position of face gear driving link 6 by feather key B7, face gear driven member 8 is inner in axle sleeve 1 right-hand member by internal circlip A9 and internal circlip B10 axial limiting, but can rotate in a circumferential direction.
As shown in Figure 2, in axle sleeve 1 left end, there is square hole, have six sides outward, can branch sleeve handle or combination wrench, on its outer wall, there are keyway and torsion indicating graduation, during concrete enforcement, rotary torsion adjusting nut 2 indicated torsion scale value on axle sleeve 1, now, step in torsion adjusting nut 2 drives feather key A4 and torsion adjustment block 3 to move axially, with this, make stage clip 5 compression or rise longly, and pressure is passed to end-tooth wheels, the maximum static friction force of face gear contact-making surface is changed.During work, the torsion that comes from spanner will pass to face gear driving link 6 by axle sleeve 1 and feather key B7, then, the frictional force contacting by the flank of tooth again passes to face gear driven member 8 by torsion, as shown in Figure 5, face gear driven member 8 one end are square toes, can connect different size sleeve, and face gear driven member 8 can pass to torsion sleeve to drive bolt rotation.When the eventually tight power of bolt reaches torque demand, between face gear driving link 6 and face gear driven member 8 contact-making surfaces, will become sliding friction from static friction, face gear driving link is along axle sleeve 1 axial runout, ticktock, now, torsion will no longer act on bolt, reach the object of determining moment of torsion assembling.
As shown in Figure 4 and Figure 5, end-tooth wheels profile of tooth is trapezoidal, while specifically implementing, between the flank of tooth, is face contact, can effectively reduce Parts and wearing and tearing that the utility model long-term work brings, extends service life of the present utility model.
