Description
Technical field
The utility model is related to a kind of detecting tool of arc spring more particularly to a kind of double mass flywheel arc springs
Radian and flatness detection plate.
Background technology
Double Mass Flywheel Type Torsional Vibration Damper, abbreviation double mass flywheel are to reduce automotive power transmission system twisting vibration
A highly effective device, it takes out shock-absorbing spring from clutch driven plate, is then arranged into engine and flown
On wheel, and forming double Mass Flywheel Type Torsional Vibration Damper so that engine flywheel has multiple functions, not only with original
Function, but also have the function of torsional vibration damper, and due to the installation radius bigger of its shock-absorbing spring, the rigidity of spring is more
Small, relative torsional angle bigger, effectiveness in vibration suppression is more ideal.
Arc arc spring working environment is severe, and stress is unstable, compared to more easy fracture for straight spring.The radian and plane of spring
Degree, which must assure that, to be bonded suitably when movement with the spring radian in double mass flywheel, can guarantee flywheel in operation process friction in this way
It minimizes, to which torque stablizes output, ensures the service life, the effect of double mass flywheel is played.
Current arc spring detection means is by the radian of projective tests arc spring, which has higher
Inaccuracy, and inefficiency.Another way is that the flatness of arc spring is detected by marble, and the detection method is same
There is inaccurate and inefficiency in sample.Therefore, those skilled in the art is dedicated to developing a kind of detection device, one
It is body formed, and the radian and flatness of arc spring can be detected simultaneously, there are higher accuracy in detection and operability.
Utility model content
In view of the drawbacks described above of the prior art, the purpose of this utility model is to provide a kind of arc spring detecting tool,
It can not be measured simultaneously with the radian and flatness that solve current arc spring, and measure complex procedures, inefficiency and accuracy
The problems such as low.
To achieve the above object, the utility model provides a kind of arc spring detection plate comprising pedestal and detect tank,
Wherein detect tank is horizontally set on the upper surface of pedestal, can detect the radian and flatness of arc spring to be detected simultaneously.
Further, detect tank outer arc is consistent with arc tolerance on the arc of arc spring to be detected, detect tank inner arc with wait for
It is consistent to detect tolerance under the arc of arc spring.
Further, the depth of detect tank is that the diameter of arc spring to be measured adds parallelism tolerance value.
Further, when arc spring to be measured is qualified products, arc spring to be measured can freely slide into detect tank, and not
Contact the inner arc and outer arc of detect tank.
Further, when arc spring to be measured is qualified products, arc spring to be measured is not present higher than detection groove depth
Region.
Further, detect tank narrowest diameter is 20~30 millimeters, and the depth of detect tank is 20~30 millimeters.
Further, a diameter of 120~150 millimeters of the outer arc of detect tank, a diameter of 100~120 milli of inner arc of detect tank
Rice.
Further, the material of detection plate is wear resistant nylon.
The advantageous effects of the utility model：
Arc spring detection plate in the utility model is integrally formed, and can measure the radian and plane of arc spring simultaneously
Degree can quickly judge that arc spring flatness is qualified and unqualified region, there is that at low cost, speed is fast, easy-operating advantage.
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Description of the drawings
Fig. 1 is a kind of three dimensional structure diagram of arc spring detection plate of a preferred embodiment of the utility model；
Fig. 2 is a kind of planar structure schematic diagram of arc spring detection plate of a preferred embodiment of the utility model；
Reference sign：Pedestal -1, detect tank -2.
Specific implementation mode
The present invention relates to a kind of detecting tool of arc spring more particularly to a kind of arcs of double mass flywheel arc spring
Degree and flatness detection plate.Carry out detailed description of the present invention preferred embodiment below with reference to attached drawing.
As shown in Figure 1, the present invention provides a kind of radian of arc spring and flatness detection plate, including pedestal 1 and inspection
Survey slot 2, wherein detect tank 2 is horizontally set on the upper surface of the pedestal 1, can detect simultaneously arc spring to be detected radian and
Flatness.
As shown in Fig. 2, the parameter of detect tank is set as, detect tank outer arc and the upper arc of the arc of arc spring to be detected are public
Poor consistent, detect tank inner arc is consistent with tolerance under the arc of arc spring to be detected, and the depth of detect tank is arc spring to be measured
Diameter add parallelism tolerance value.
In the present embodiment, a diameter of 23.7 millimeters of spring to be measured, positive and negative deviation is 0.2 millimeter, outer arc a diameter of 135.6
Millimeter, positive and negative deviation are 6 millimeters, and flatness is 2 millimeters.Fig. 2 shows the parameter of the detect tank of the above-mentioned arc spring of detection,
Diameter (most narrow place's width) is 23.7 millimeters, and a diameter of 144.5 millimeters of outer arc, positive and negative deviation is 0.2 millimeter, and inner arc is a diameter of
105.9 millimeters, positive and negative deviation is 0.2 millimeter, and the depth of tooling is 24.6 millimeters.
When radian checks, arc spring is pushed into tooling, if spring can smoothly slide into tooling, and not with interior outer arc phase
The radian for contacting then spring is qualification.If can not freely fall into, then it is assumed that radian is unqualified.
When flatness detects, after spring is fallen into radian slot, the peak of spring then thinks spring not higher than tooling face
Flatness is qualified.If being higher than tooling surface, then it is assumed that spring plane degree is unqualified.
The material that detection plate uses in the present embodiment is wear resistant nylon, mainly utilizes the low-friction coefficient of wear resistant nylon,
There are lower hardness and rub resistance wear characteristic relative to arc spring to be measured.Test quantity in production process is relatively more,
Test panel premature abrasion is can avoid using this material to fail.Simultaneously because hardness is less than spring, spring can avoid during the test
By high hardness material sliding injury.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
