Abstract
An accurate fixed torque spanner is used for fixed torque assembling of a bolt or a nut; a torque force fine tuning nut and a torque force coarse tuning nut are respectively arranged inside and outside a shaft sleeve; the torque force fine tuning nut and torque force coarse tuning nut can be adjusted to determine torque; a driven member on the end of a drive member is screwed, so the drive member axially moves, thus triggering a pressure alarm device in the torque force fine tuning nut to send alarms. When a torque value is set in advance, an operator does not need to watch scale indication, and the pressure alarm device can automatically determine whether the bolt or nut assembling reaches the fixed torque value or not. The drive member and driven member are in thread fitting, so wearing and fatigue caused by long time application can be effectively reduced, and the torque value can be accurately set. The accurate fixed torque spanner is simple in structure and convenient in usage.
Description
Technical field
The present invention relates to technical field of tools, a kind of spanner determining moment of torsion assembling for bolt or nut.
Background technology
At present, known torque sleeve barrel spanner has the types such as mechanical audible alarm formula and pointer dial type, wherein, application more generally machinery audible alarm formula spanner, is adjusted screw etc. constituted by ratchet, compression spring, torsion locking joint, torsion, there will be mechanical collision sound when moment of torsion reaches setting value, if but exert oneself again, can cause the excessive phenomenon of torsion, this type of spanner is also easy to occur that compression spring is tired so that torque value error increases；Locking joint is easy to wear so that torque value cannot lock；Ratchet is easy to wear so that spanner cannot normally work.Main cause is that the primary structure member of this type of spanner mostly is Points And lines contact, and its stress is concentrated, rapid wear.Additionally pointer dial type spanner is also susceptible to torsion gage damage or error so that torque value misregister.
Additionally, known torque sleeve barrel spanner moment of torsion adjusting range is little, it is impossible to accurately positioning torque value, range of error is big.
Summary of the invention
For overcoming the deficiencies in the prior art, the goal of the invention of the present invention is to provide a kind of accurately constant torque wrench, to realize the accurate of bolt is determined moment of torsion assembling, and working stability.
For reaching above-mentioned purpose, inside and outside torsion fine-tuning nut, the torsion coarse adjustment nut of being respectively provided with of axle sleeve of the present invention, adjusts torsion fine-tuning nut and determines moment of torsion with torsion coarse adjustment nut, rotate the driven member of driving link end, driving link moves axially, and triggers the pressure warning unit in torsion fine-tuning nut and reports to the police.
In described axle sleeve, one end is with threaded torsion fine-tuning nut, is provided with pressure warning unit in torsion fine-tuning nut, and torsion fine-tuning nut finely tunes indicating graduation with torsion；Sleeve outer circle side face with threaded torsion coarse adjustment nut, on sleeve outer circle side face, axle sleeve with torsion coarse adjustment nut junction with coarse adjustment indicating graduation；Torsion adjustment block it is set with in axle sleeve, torsion adjustment block is provided with the spring pin for positioning torsion adjustment block, spring pin coordinates with the keyway on axle sleeve, one end of driving link is contained in the through hole of torsion adjustment block, to to pressure warning unit, compression spring is enclosed within driving link, it is located between torsion adjustment block and the boss of driving link, the other end of driving link is provided with spring pin, spring pin coordinates with the keyway on axle sleeve, limit rotating in a circumferential direction of driving link, the driven member that can rotate in a circumferential direction is threadeded with driving link, it is limited in the end of axle sleeve by the boss of driven member with axle sleeve.
Before twisting bolt or nut, rotary torsion coarse adjustment nut and torsion fine-tuning nut are in the moment of torsion scale value of regulation, and the pressure of compression spring is acted on by torsion adjustment block and actively goes up part by torsion coarse adjustment nut.When twisting bolt or nut, spanner connects different size sleeve,Torsion from pinch bar acts on driving link by driven member, driving link axially-movable is driven by screw thread rotation, when bolt or nut screwing clamping power arrive prescribed torque value, driving link contacts with the pressure warning unit in torsion fine-tuning nut, pressure warning unit sends chimes of doom, to realize the purpose of fixed-torsional moment assembled bolt or nut.
Whether compared with prior art, after making a reservation for set torque value, operator need not observe graduation indication to the present invention again, assembled by pressure warning unit energy automatic decision bolt or nut and reach to determine torque value.Owing to passing through threaded engagement between driving link and driven member, can effectively reduce the produced abrasion of life-time service and fatigue, can accurately torque value be set simultaneously.Simple in construction, easy to use.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, in axle sleeve 1, one end is with threaded torsion fine-tuning nut 2, is provided with pressure warning unit 3 in torsion fine-tuning nut 2, and torsion fine-tuning nut 2 finely tunes indicating graduation 10 with torsion；Axle sleeve 1 outer circumference surface is with threaded torsion coarse adjustment nut 4；Torsion adjustment block 6 it is set with in axle sleeve 1, torsion adjustment block 6 is provided with torsion coarse adjustment indicating graduation 11, for positioning the spring pin 5 of torsion adjustment block 6, spring pin 5 coordinates with the keyway on axle sleeve 1, one end of driving link 8 is contained in the through hole of torsion adjustment block 6, to to pressure warning unit 3, compression spring 7 is enclosed within driving link 8, it is located between the boss of torsion adjustment block 6 and driving link 8, the other end of driving link 8 is provided with spring pin 5, spring pin 5 coordinates with the keyway on axle sleeve 1, limit rotating in a circumferential direction of driving link 8, the driven member 9 that can rotate in a circumferential direction is threadeded with driving link 8, it is limited in the end of axle sleeve 1 by the boss of driven member 9 with axle sleeve 1.Determining moment of torsion by adjusting torsion fine-tuning nut 2 and torsion coarse adjustment nut 4, rotate the driven member 9 of driving link 8 end, driving link 8 moves axially, and the pressure warning unit 3 triggered in torsion fine-tuning nut 2 is reported to the police.
During concrete operations, coarse adjustment indicating graduation 11 according to torsion adjustment block 6, rotary torsion coarse adjustment nut 4, set thick moment of torsion by setting, then adjust torsion fine-tuning nut 2 according to torsion fine setting indicating graduation 10, set micro-moment of torsion by setting, now, torsion adjustment block 6 drives torsion adjustment block 6 to move axially by spring pin 5, makes compression spring 7 compress or extend, and the torsion coming from spanner drives the bolt that need to tighten or nut to rotate by driven member 9.When bolt or nut screwing clamping power reach torque demand, driven member 9 rotates in a circumferential direction, by screw drive driving link 8 axially-movable, when driving link 8 one end contacts with pressure warning unit 3 in torsion fine-tuning nut 2, pressure warning unit 3 will send chimes of doom, to reach to determine the purpose of moment of torsion assembling.
