Description
Technical field
The present invention relates to bolt washer technical field, be specifically related to a kind of can even twisting moment or the elastic washer that makes moment of torsion quantify.
Background technology
In machining or in a lot of fields such as Coal Mechanical, the situation of bolt use elastic washer is fairly common.Elastic washer can apply outside tension force to the cap end of bolt, thus prevents bolt looseness.But bolt is rotated in fixation procedure, be difficult to hold bolt constant depth, the inconsistent situation of elastic washer tension force can be caused, make equipment fixed performance be deteriorated.For a lot of mechanical assembly, the pressure between bolt and elastic washer should be fixed on a particular range, should be the not biggest or the least.Being currently used for realizing elastic washer at the instrument of particular pressure range is to use to determine torque tool, such as constant torque wrench.Determine torque tool volume relatively big, heavy inconvenient to carry, use laborious, inefficient, and cannot operate in narrow regions.
Existing determine the mistake malfunctioning mechanism of moment of torsion that torque tool really arranged by instrument itself and realize preventing moment of torsion problems of too, this mode preventing moment of torsion excessive is the given torque tool of transmission after bolt is by " maximum " rotational resistance, makes to determine torque tool and is not further added by torsional forces degree.But bolt is a lot of by resistance factor, in addition to elastic washer provides outside tension factor, also affected with screw matching degree factor by bolt, and in screw, the factor such as entering part barrier is affected.So, using and determine torque tool it sometimes appear that bolt screws incomplete phenomena, this there will be unavoidably by the way of transmission bolt torque determines to screw effect, screws situation the most up to standard.
Summary of the invention
It is an object of the invention to provide and a kind of can make bolt fixation procedure overcomes to the dependency determining torque tool with even twisting moment or the elastic washer quantifying moment of torsion, improve the operability of portability, motility and optional position that bolt is installed.
For achieving the above object, the present invention adopts the following technical scheme that torque washers is determined in employing, and including upper gasket and lower gasket, the middle part of upper and lower packing ring is respectively arranged with the centre bore of correspondence for running through installation bolt；Centre bore at lower gasket is distributed about is fixed with multiple symmetrical elastomer, and the upper end of each symmetrical elastomer is slidably matched with upper gasket inner surface；And between upper gasket and lower gasket, it is provided with the detent mechanism for determining two packing ring spacing.
Described detent mechanism is to be fixed with at least one along axis on the inner surface of any one packing ring to position bar for the measured length retraining two packing ring maximum compressibility.
Described detent mechanism is to fix rule respectively in axial direction and with reference to bar at the inner surface of two packing rings, and bar side face or end are provided with the line of reference corresponding with rule graticule.
Described symmetrical elastomer is V-type shell fragment, and the turning of V-type shell fragment is fixed on lower gasket inner surface by rivet or solder joint, and V-type shell fragment upper end is respectively arranged with shoes.
Inner surface at upper gasket is provided with and V-type shell fragment respective amount and the chute of correspondence position, and the shoes of each V-type shell fragment upper end lays respectively in chute, and is slidably matched.
Described chute is all laid in around the centre bore of upper gasket；Or, described chute interval sequence distribution: the center of adjacent chute is not on same periphery, so that the shoes of adjacent V-type shell fragment upper end does not interferes.
Inner surface at upper gasket is provided with and V-type shell fragment respective amount and the chute of correspondence position, and this chute is for retraining the aperture of V-type shell fragment upper end two shoes, thus realizes the location of the spacing of two packing rings.
The invention has the beneficial effects as follows:
1, as can be seen from the above technical solutions, be may determine that the spacing of upper gasket and lower gasket by detent mechanism, spacing i.e. can determine that the Elastic penetration between upper gasket and lower gasket after determining, thus the purpose of assembling under the conditions of realizing specified torque.The location amount of detent mechanism is by the overall elasticity index impacts of symmetrical elastomer, after the overall elasticity coefficient of symmetrical elastomer determines, the elastic pressure between two packing rings with it apart from inversely proportional linear relationship.
2, the realization of detent mechanism, can be to use the limit location mode of measured length, it would however also be possible to employ rule realizes length-specific in certain limit determine the adjustable positioning mode of specified torque with interlocking with reference to bar.
3, the structure that chute coordinates is used with shoes, it is possible not only to prevent upper and lower packing ring from producing relative rotation problem, can also retrain symmetrical elastomer makes it slide along assigned direction, prevent elastomer to be destroyed because of reasons such as stress are asymmetric, such as, be also prevented between V-type shell fragment upper end two shoes and adjacent shoes mutual collision problem.
4, the stretching degree of V-type shell fragment upper end two shoes can be retrained by another effect of chute, and V-type shell fragment upper end two shoes is prevented from when arriving chute two ends step surface, thus the situation also constraining two packing rings to compress further, start positioning action.
5, present configuration is reasonable in design, easily realizes, and its product can substitute existing must employing after throwing in use and determine torque tool, can be operated by the electric or hand instrument arbitrarily coordinated with bolt, such that it is able to reduction job costs, alleviate additional workload, improve work efficiency.The fixed torque bolt being particularly suited in narrow regions is installed, and effect is the best, is suitable for popularization and application.
