Put and be connected by spring scale between inside ceiling panel and outer frame body top board, pull clamping device clamping by spring scale is arranged with preset force
Measuring the height of wavy spring, drawing corresponding relation highly and preset force between for the wavy spring thus whether measuring wavy spring
Qualified；But this test device structure is more complicated, complex operation, surveying record height when operator need in operation in measurement
Value, operation need to have experience human users；Secondly, the height after needing kind of calliper spring compression in measurement, and wave recording
Corresponding relation between height after spring compression and spring scale preset force, draws the preset force curve of wavy spring, and it draws bent
There is deviation in line, and then affect certainty of measurement；Again, if design requirement wavy spring is sentenced when high variable quantity very little
Whether disconnected spring force is qualified, draws curve and more bothers, and error is larger.
Content of the invention
For solving above-mentioned technical problem, the invention provides a kind of spring force measuring device for electromotor wavy spring
And measuring method.
The present invention is achieved by the following technical programs.
A kind of spring force measuring device for electromotor wavy spring, including balancing weight, standard ring, chassis, dial framework and
High leg, described standard ring is arranged on chassis, and described balancing weight passes through standard ring and is connected in the mating holes being arranged on chassis
Together, described dial framework is arranged on below chassis by screw and straight pin, described dial framework is fixed with dial gauge by table folder, institute
State high leg to be fixedly mounted on below chassis.
Table folder nut is provided with described dial gauge.
Described balancing weight both sides are provided with handle.
It is provided with counterweight above described balancing weight.
Described handle is arranged symmetrically in balancing weight both sides.
A kind of method using the above-mentioned spring force measuring device power for electromotor wavy spring, the method is first will to join
Pouring weight lower end links together through standard ring, and is placed on chassis by the mating holes on chassis, observe dial gauge and by its
Pointer adjusts 0；Taking-up standard ring, replaces standard ring with wavy spring, repeats aforesaid operations, and observation caliber ring and wavy spring are being joined
The change that under pouring weight gravity, dial gauge occurs, you can whether the variable quantity according to dial gauge is in the range of free height, and then sentences
Whether disconnected spring force reaches design requirement.
The beneficial effects of the present invention is：
Compared with prior art, spring force is converted to gravimetric value by the present invention, and makes balancing weight according to this gravimetric value；Mark
Lead ring height H simulates spring free height value H0, in measurement apparatus, difference observation caliber ring and wavy spring are in balancing weight
The change that under gravity, dial gauge occurs.By this measurement of comparison, whether the variable quantity according to dial gauge is in free height H0Model
In enclosing, judge whether spring force reaches design requirement.This metering system is in production scene convenient and reliable operation, as long as operator
Simply compared measurement and just can be judged that whether qualified part is, observed measurement result simple, intuitive；Even if to design requirement ripple
Shape spring judges whether spring force qualified when high variable quantity very little, also can simple, intuitive judge whether qualified.
