Description
Technical field
The utility model is related to the intrinsic parametric measurement fields of spring, and digital millisecond counter is specifically utilized to measure spring letter
The period of harmonic motion, and then the device by the way that its stiffness factor is calculated.
Background technology
The stiffness factor of spring is also referred to as coefficient of elasticity, coefficient of stiffiness etc., is that one of characterization spring build-in attribute is important
Parameter.The assay method of device of spring stiffness coefficient includes static method, dynamic method etc., and wherein dynamic method is because easy to operate, result is opposite
Accurately like by people.Dynamic method needs to measure the period that spring does simple harmonic oscillation.
Digital millisecond counter is a kind of more accurate electronic timing equipment, and operation principle is generated using crystal oscillator
High frequency electric pulse carrys out timing, and accuracy of timekeeping is up to 10-4 s.In use, the method that photoelectric door can be blocked by anti-dazzling screen, simultaneously
Record number and corresponding time of the anti-dazzling screen Jing Guo photoelectric door.Also, the instrument has store function, can record multigroup number
According to, and have " clearing " function, use can be wiped repeatedly.
Problem of the existing technology:Existing technology measures the week of spring oscillator using traditional manual time-keeping method
Phase often since operator presses the delay of stopwatch or shifts to an earlier date, and causes period measurement inaccurate.
Utility model content
In view of the deficiencies in the prior art, the utility model provides a kind of device of spring stiffness coefficient measurement device.
The utility model uses the following technical solution:
A kind of device of spring stiffness coefficient measurement device includes mainly:A shape frame is installed on holder, holder, is pacified in door shape frame
It fills spring to be measured, connects cross barn door below spring, connecting trays below cross barn door place counterweight, counterweight in pallet
Variable mass;Photoelectric door is installed below door shape frame, photoelectric door is wired to millisecond meter.
Preferably, photoelectric door is fixed on by movable screw rod on frame, and upper and lower position is adjustable.
Preferably, door shape frame is connected using activity riveting with holder, and a shape frame is enable to be rotated around bracket end 360o.
Advantageous effect:When the utility model can solve traditional measurement spring oscillator vibration period with stopwatch, there are errors
The problem of.Door shape frame can be rotated around bracket end 360o, not be that total energy face is placed to solve cross barn door and photoelectric door
Problem.Photoelectric door is fixed on by movable screw rod on frame, and upper and lower position is adjustable, to solve length difference or spring
It is extended naturally because usage time is long, it is not the problem of total energy face is placed to make cross barn door and photoelectric door.In an experiment
The position of photoelectric door is adjusted, anti-dazzling screen is exactly in the center of photoelectric door when keeping spring static.
Description of the drawings

9 lower section connecting trays 6 are placed with counterweight 10 in pallet 6;3 lower section of door shape frame is equipped with photoelectric door 4, photoelectricity by fixing bolt 5
Door 4 is connected to millisecond meter 8 by conducting wire 7.
Embodiment 2
A kind of device of spring stiffness coefficient assay method is present embodiments provided, as shown in Fig. 1, which includes as follows
Step:
1, spring 2 to be measured is fixed on a shape frame 3, and connects cross barn door 9 and pallet 6, counterweight is placed in pallet 6
10;
2, the position for adjusting fixing bolt 5, makes photoelectric door 4 and 9 face of cross barn door;
3, setting millisecond meter 8 reaches dormant state, and pallet 6 is pulled downward on a distance and is discharged;
4, number S of the cross barn door 9 Jing Guo photoelectric door 4 is read by millisecond meter 8iWith corresponding time ti, pass through formula
T=(ti+2-ti)/(Si+2-Si),(i=1,2,3……), calculate the cycle T of spring oscillator movement;
5, the quality for changing counterweight 10 measures the period corresponding to multigroup different counterbalance mass.Pass through formula T2=(4π2/K)
