Abstract
The invention belongs to the measurement technology of dynamic torque, and particularly relates to a torque buffer. The torque buffer comprises a shell (1), a screw (3), a nut (4), a mother spring (5), a son spring (6) and a son pushing bearing (7); and the top of the screw (3) is installed on the son pushing bearing (7), the screw (3) and the son pushing bearing (7) are installed in a shell cavity together, the son spring and the mother spring penetrate the position, at the bottom of the screw and between the screw and the nut, of the nut, and the son spring is wrapped with the mother spring. Two antisymmetrical inclined guide grooves are formed in the side wall of the shell cavity, and two guide rods of the nut (4) are located in the two antisymmetrical inclined guide grooves. According to the torque buffer, the son-mother dual spring design is adopted, and meanwhile the guide grooves in the shell are designed to be the spirally-climbing type oblique-line guide grooves, so that the stroke is effectively buffered; and the ascending angle of the guide grooves is changed, so that the stress state of the nut in the motion process is changed, and the buffer capacity of the buffer can be greatly improved under the condition that the volume is not changed.
Description
Technical field：
The invention belongs to the e measurement technology of dynamic torque, and in particular to a kind of moment of torsion buffer.
Background technology：
May require that in the Automated assembly such as automobile making, aircraft manufacturing field and product fastener is tightened, producing
When product securing member is tightened, need the moment of torsion of securing member is measured and monitored.General measure is divided into static torque measurement and moves
State torque measurement.During using static torque instrument calibrating/calibration electricity, aerodynamic moment spanner, it is necessary to consider dynamic impulsion to static state
The impact of torquemeter measurement accuracy.At present, the way that domestic and international professional production business generally adopts is at both connecting interfaces
Increase moment of torsion buffer, to reduce dynamic impulsion as far as possible, it is ensured that the degree of accuracy of final measurement meets requirement.
Moment of torsion buffer on the market is constrained by its structure, principle, carries often excessive, heavy because of volume during high pulling torque
Amount is too heavy, and not readily portable and use.
The content of the invention：
The purpose of the present invention is：A kind of simple structure, small volume, lightweight moment of torsion buffer are provided.
The technical scheme is that：A kind of moment of torsion buffer, which includes housing 1, screw rod 3 and nut 4, female spring 5, son
Spring 6, sub- thrust bearing 7, are arranged at the top of screw rod 3 on sub- thrust bearing 7, and both are installed along with housing chamber, in spiral shell on nut
Bar bottom, wears sub-spring and female spring between screw rod and nut, female spring inside diameter is slightly larger than sub-spring external diameter, by sub-spring bag
Internally.
Housing chamber side wall is provided with the oblique guide groove of two antisymmetry, and the oblique guide groove of described two antisymmetry is centrally located at
On housing cavity axis.
The nut both sides have guide post, and guide post is located in oblique guide groove.
When screw rod is subject to dynamic torque and rotates at a high speed, nut can be driven along on two antisymmetry skewed slots on housing
Rise so as to compress female spring and sub-spring, primary and secondary spring can be prevented the rotation of screw rod by the reaction force produced in compression process,
So as to play cushioning effect.
The housing chamber bottom is provided with the base 2 installed for moment of torsion buffer.
The solution have the advantages that：Moment of torsion buffer of the present invention is except the basic function of reservation conventional torque buffer
Outward, following improvement has also been carried out：1) buffer spring is designed as into two springs of primary and secondary, sub-spring is enclosed within female spring, same
In the case of volume, the bearing torque ability of primary and secondary spring and buffering effect are higher；2) conventional straight-line guidance groove is changed to spiral to climb
Type oblique line gathering sill is risen, by increasing frictional force come Promoting Layered Buffer effect, while also add effective cushion stroke；3) present invention
Moment of torsion buffer structure is compact, in the case of comfort cushioning effect is ensured, greatly reduces the volume and weight of high pulling torque buffer.
Description of the drawings：
Fig. 1 is the front view of moment of torsion buffer of the present invention；
Fig. 2 is the left view of moment of torsion buffer of the present invention,
Wherein, 1 it is housing, 2 be base, 3 is screw rod and 4 is nut, 5 is female spring, 6 is sub-spring, 7 is sub- push shaft
Hold, 8 be oblique guide groove, 9 be guide post.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 and Fig. 2 is referred to, moment of torsion buffer of the present invention includes housing 1, screw rod 3 and nut 4, female spring 5, sub-spring
6th, sub- thrust bearing 7.The screw rod is seated on sub- thrust bearing, and as sub- thrust bearing is rotated, the two is installed in housing cavity together.
The nut with guide post is arranged on screw rod bottom.Meanwhile, sub-spring and female spring, female bullet are worn between screw rod and nut
Spring internal diameter is slightly larger than sub-spring external diameter, by sub-spring bag internally.In addition, housing chamber side wall to be provided with two antisymmetry oblique
To guide groove, the oblique guide groove of described two antisymmetry is centrally located on housing cavity axis, and the guide post of the nut is arranged on two
In the oblique guide groove of individual antisymmetry, therefore screw rod can be avoided from being affected by side force in rotary course, and be deflected.Together
When, conventional straight-line guidance groove is changed to into the soaring type oblique line gathering sill of spiral, by increasing frictional force come Promoting Layered Buffer effect, together
When also add effective cushion stroke, improve the buffering effect in limited distance.
In addition, whole moment of torsion buffer carries out installation fixation by base.
When using the moment of torsion buffer, first the base 2 of moment of torsion buffer is fixed on torductor, by dynamic
Moment of torsion is acted on moment of torsion buffer by the head interface of screw rod 3, when screw rod is subject to dynamic torque and rotates at a high speed, can band
Dynamic nut rises so as to compress female spring and sub-spring along two antisymmetry skewed slots on housing, and primary and secondary spring is by compression process
The reaction force of middle generation can prevent the rotation of screw rod, so as to play cushioning effect.Through the cushioning effect of moment of torsion buffer, will
The dynamic torque rotary speed and dynamic impulsion of measurement is needed to reduce, so that torductor can accurately measure the moment of torsion
The size of value.
