Kind waveform spring pre-pressure testing device, including an outer frame body are internally provided with waveform spring clamping device in outer frame body, clamp dress
It sets and is connected by spring scale between inner top panel and outer frame body top plate, pull clamping device to clamp by the way that preset force is arranged to spring scale
The height for measuring waveform spring draws the correspondence between waveform spring height and preset force to whether measure waveform spring
It is qualified；But the test device structure is more complex, cumbersome, and when measuring, operating personnel need to measure record height in operation
Value, operation need to have experience personnel operation；Secondly, the height after needing calliper spring compression when measuring, and wave recording
Correspondence between height after spring compression and spring scale preset force draws the preset force curve of waveform spring, draws bent
There are deviations for line, and then influence measurement accuracy；Again, if design requirement waveform spring is sentenced when high variable quantity very little
Whether disconnected spring force is qualified, draws curve and is more troublesome, and error is larger.
Invention content
In order to solve the above technical problems, the present invention provides a kind of spring force measuring devices for engine waveform spring
And measurement method.
The present invention is achieved by the following technical programs.
A kind of spring force measuring device for engine waveform spring, including clump weight, standard ring, chassis, dial framework and
High stabilizer blade, the standard ring are mounted on chassis, and the clump weight passes through standard ring and the matching hole being arranged on chassis to be connected in
Together, the dial framework is mounted on by screw and straight pin below chassis, is fixed with dial gauge by table folder on the dial framework, institute
High stabilizer blade is stated to be fixedly mounted below chassis.
Table folder nut is provided on the dial gauge.
The clump weight both sides are provided with handle.
It is provided with counterweight above the clump weight.
The handle is arranged symmetrically in clump weight both sides.
A method of using the above-mentioned spring force measuring device power for engine waveform spring, this method is will first to match
Pouring weight lower end links together across standard ring, and is placed on chassis by the matching hole on chassis, observe dial gauge and by its
Pointer tune 0；Taking-up standard ring replaces standard ring with waveform spring, repeats aforesaid operations, observation caliber ring and waveform spring with
The variation that dial gauge occurs under pouring weight gravity, you can according to the variable quantity of dial gauge whether within the scope of free height, and then sentence
Whether disconnected spring force reaches design requirement.
The beneficial effects of the present invention are：
Compared with prior art, spring force is converted to gravimetric value by the present invention, and clump weight is made according to the gravimetric value；Mark
Lead ring height H simulation spring free height values H0, observation caliber ring and waveform spring are distinguished in measuring device in clump weight
The variation that dial gauge occurs under gravity.By this measurement of comparison, according to the variable quantity of dial gauge whether in free height H0Model
In enclosing, judge whether spring force reaches design requirement.This measurement method is in production scene convenient and reliable operation, as long as operator
Carrying out simple relatively measure can judge that part is qualified or not, observe and measure result simple, intuitive；Even if to design requirement wave
Shape spring judges whether spring force qualified when high variable quantity very little, also can simple, intuitive judge whether qualification.
