Description
Technical field：
The invention belongs to the measuring techniques of dynamic torque, and in particular to a kind of torque buffer.
Background technology：
It may require that in the Automated assemblies such as automobile making, aircraft manufacturing field and product fastener tightened, producing
When product fastener is tightened, need that the torque of fastener is measured and monitored.General measure is divided into static torque and measures and move
State torque measurement.When using static torque instrument calibrating/calibration electricity, aerodynamic moment spanner, it is necessary to consider dynamic impulsion to static state
The influence of torquemeter measurement accuracy.Currently, the way that professional production quotient generally uses both at home and abroad is at the two connecting interface
Increase torque buffer, to reduce dynamic impulsion as far as possible, it is ensured that the accuracy of final measurement is met the requirements.
Torque buffer on the market is constrained by its structure, principle, often because volume is excessive, again when carrying large torque
Amount is too heavy, without easy to carry and use.
Invention content：
The purpose of the present invention is：A kind of torque buffer simple in structure, small, light-weight is provided.
The technical scheme is that：A kind of torque buffer comprising shell 1, screw rod 3 and nut 4, female spring 5, son
Spring 6, sub- thrust bearing 7,3 top of screw rod are mounted on sub- thrust bearing 7, and the two is installed along in housing chamber, in spiral shell on nut
Sub-spring and female spring are worn in bar bottom between screw rod and nut, female spring inside diameter is slightly larger than sub-spring outer diameter, by sub-spring packet
In inside.
There are two the oblique guide grooves of antisymmetry for the housing chamber side wall setting, and described two oblique guide groove centers of antisymmetry are located at
On shell cavity axis.
There is guide rod, guide rod to be located in oblique guide groove for the nut both sides.
In screw rod by dynamic torque and when high speed rotation, nut can be driven along on two antisymmetry skewed slots on shell
It rising to compress female spring and sub-spring, primary and secondary spring can be prevented the rotation of screw rod by the reaction force generated in compression process,
To play cushioning effect.
The housing chamber bottom is provided with the pedestal 2 installed for torque buffer.
The solution have the advantages that：Basic function of the torque buffer of the present invention in addition to retaining conventional torque buffer
Outside, following improvement has also been carried out：1) buffer spring is designed as two springs of primary and secondary, sub-spring is sleeved in female spring, same
In the case of volume, the bearing torque ability and buffering effect of primary and secondary spring are stronger；2) conventional linear guide groove spiral is changed to climb
Type oblique line guide groove is risen, by increasing frictional force come Promoting Layered Buffer effect, while also adding effective cushion stroke；3) of the invention
Torque buffer structure is compact, is ensureing comfort cushioning effect, is greatly reducing the volume and weight of large torque buffer.
Description of the drawings：
Fig. 1 is the front view of torque buffer of the present invention；
Fig. 2 is the left view of torque buffer of the present invention,
Wherein, 1 it is shell, 2 be pedestal, 3 is screw rod and 4 is nut, 5 is female spring, 6 is sub-spring, 7 is sub- push shaft
It holds, 8 be oblique guide groove, 9 be guide rod.
Specific implementation mode
The present invention will be further described with reference to the accompanying drawings and examples：
It please refers to Fig.1 and Fig. 2, torque buffer of the present invention includes shell 1, screw rod 3 and nut 4, female spring 5, sub-spring
6, sub- thrust bearing 7.The screw rod is seated on sub- thrust bearing, and as sub- thrust bearing rotates, the two is installed in housing cavity together.
The nut with guide rod is mounted 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 outer diameter, by sub-spring packet in inside.In addition, there are two antisymmetry is oblique for the housing chamber side wall setting
To guide groove, described two oblique guide groove centers of antisymmetry are located on housing chamber axis, and the guide rod of the nut is arranged two
It in a oblique guide groove of antisymmetry, therefore can be influenced, and be deflected by lateral force in rotary course to avoid screw rod.Together
When, conventional linear guide groove is changed to the soaring type oblique line guide groove 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, entire torque buffer carries out installation fixation by pedestal.
When using the torque buffer, the pedestal 2 of torque buffer is fixed on torductor first, it will dynamic
Torque is acted on by the head interface of screw rod 3 on torque buffer, can band in screw rod by dynamic torque and when high speed rotation
Dynamic nut rises along two antisymmetry skewed slots on shell to compress female spring and sub-spring, and primary and secondary spring is by compression process
The reaction force of middle generation can prevent the rotation of screw rod, to play cushioning effect.It, will by the cushioning effect of torque buffer
The dynamic torque rotary speed measured and dynamic impulsion is needed to reduce, to enable torductor to accurately measure the torque
The size of value.
