Description
Technical field
The utility model is related to a kind of ω types spring symmetry pendulum pin type Quick detection tools.
Background technology
The method of inspection of symmetry index is excessively cumbersome in existing ω types spring, cannot quickly be examined in mass production
It surveys, original detection method is as shown in Figure 1, first detecting left side size a1 using professional mould and vernier caliper and recording, so
After detect that right side and records size a2, number of the absolute value of a1-a2 as ω spring symmetries is calculated according to record result
Value, the numerical value are less than specified value for qualification.The measuring method is needed to carry out operator the training that vernier caliper uses and wanted
Operator is asked to be carried out at the same time record and calculating in measurement process.
The content of the invention
The shortcomings that the utility model is overcome in the prior art provides a kind of ω types spring symmetry pendulum pin type and quickly examines
Tool.
The technical solution of the utility model is：A kind of ω types spring symmetry pendulum pin type Quick detection tool including pedestal and is set
Put origin reference location plate, reference axis, balancing point and adjustable graduated disk on pedestal；The reference axis is fixedly mounted on pedestal center line
On, the balancing point and adjustable graduated disk are symmetrically mounted at left and right sides of reference axis, and reset is equipped in the shaft of balancing point and is turned round
Spring.
Compared with prior art, the utility model has the advantages that：
Measurement procedure is simplified, spring coordinates dial scale using pointer afterwards in place, need not use vernier caliper, be not required to
It is calculated, whether the symmetry of spring can be directly measured using the amplitude of fluctuation of pointer is transfinited.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is existing ω springs symmetry detects schematic diagram；
Fig. 2 is the structure diagram of this cubing.
Specific embodiment
A kind of ω types spring symmetry pendulum pin type Quick detection tool, as shown in Fig. 2, including：Pedestal 1, origin reference location plate 2, base
Fiducial axis 3, reduction torsion spring 4, balancing point 5, pointer adjusting mechanism 6, graduation mark 7, adjustable graduated disk 8 etc., wherein：
Pedestal 1 is the carrying platform of all components；
Positioning datum of the origin reference location plate 2 for spring when in place, is fixed on carrying platform；
Positioning datum when reference axis 3 is tested for spring, is fixedly mounted on carrying platform center line；
Reduction torsion spring 4 is pointer reset torsional spring, in the shaft of balancing point；
Balancing point 5 is swingable pointer；
Pointer adjusting mechanism 6 is mounted on carrying platform, and the initial position of left and right balancing point can be adjusted；
Graduation mark 7 is the scale mark on dial；
Adjustable graduated disk 8：On carrying platform, link and adjust with pointer adjusting mechanism.
It is needed when being tested using the utility model to ω type spring symmetries first according to certain model spring width dimensions mark
Balancing point and dial position (symmetrical calibration) are set, can carry out symmetry to the type spring after calibration is good quickly measures,
By the closely connected origin reference location plate of spring afterbody during inspection, with hand propelled spring by the left closely connected reference axis of limb in the middle part of spring, right side at this time
Pointer generates swing under the promotion at the right limb edge of spring, and spring scale pointed by the balancing point of observation right side afterwards in place writes down numerical value
Pusher is moved item, by the right closely connected reference axis of limb in the middle part of spring (right side pointer will automatically reset in case next time measures at this time), at this time
Left side pointer is subject to the promotion at the left limb edge of spring and generates swing, observes left side balancing point after spring is in place again and is directed toward scale, with
Just now the scale value of right side pointer was compared, and the difference of left and right scale is no more than specified value and can determine that spring symmetry to close
Lattice.Spring is then taken out, left side balancing point is automatically reset due to the taking-up of spring.The measurement of subsequent product can then be carried out.
In order to more intuitively compare scale pointed by the balancing point of left and right simultaneously, spring is promoted by the left closely connected benchmark of limb in the middle part of spring
Axis, at this time right side pointer generates swing under the promotion at the right limb edge of spring, spring in place, after right side balancing point stops swinging,
Balancing point swing position is fixed by pointer adjusting mechanism 6；Then spring is promoted, by the right closely connected benchmark of limb in the middle part of spring
Axis, at this time left side pointer be subject to the promotion at the left limb edge of spring and generate swings, spring in place, left side balancing point stops swinging
Afterwards, while paired observation left and right side balancing point amplitude of fluctuation, if the difference of the two is no more than specified value and can determine that spring symmetry
For qualification.Spring is then taken out, both sides balancing point is resetted, then can carry out the measurement of subsequent product.
Using cubing and method before, measurement is comparatively laborious, needs to record numerical value in measurement and be calculated, measurement knot
Fruit is influenced by measurement people using slide calliper rule ability, and due to that must be recorded and be calculated, adds the possibility of error.This
Utility model easily can be measured quickly for various sizes of ω types spring symmetry, directly compared left and right pointer and carved
The numerical value of degree because contrast number is reduced to integer value by dial, need not be recorded and calculated and can obtain symmetry difference,
Quick detection that is convenient and efficient, being particularly suitable in this kind of high volume production process of spring.
It is the left-right deviation based on spring center line that the utility model, which fully takes into account spring symmetry, the measuring device and
Measuring method all considers the measurement of the progress symmetry on the basis of the center line of spring completely, meets the type spring symmetry
Control requirement.And the utility model, by pointer and dial, the concrete numerical value that will be gone out with calliper is reduced to carve in the past
Integer value on scale eliminates the process of record and calculating, directly can draw difference range by comparison.
