Abstract
The invention discloses a flatness detection device which is used for detecting flatness of an oil seal of a transmission and comprises a detection platform, a dial and a rotator. The rotator is provided with a probe. The detection device is characterized in that the dial comprises a large dial and a small dial; the detection platform and the large dial are an integrated disc; the small dial is disposed above the large dial; and the small dial and the large dial share the same center of a circle. The flatness detection device has a simple structure and high detection precision, and can be used to rapidly and accurately detect flatness of an oil seal of a transmission. A flatness detection method is simple to operate, has small error and can be adopted to effectively solve the oil leakage problem of the oil seal of the transmission.
Description
Technical field
The present invention relates to a kind of flatness checking device and detection method, more particularly, to speed changer oil sealing flatness detection dress
Put and detection method.
Background technology
Automotive transmission is for coordinate the speed change gear of the rotating speed of engine and the actual travel speed of wheel, being shadow
Ring the vitals of automotive safety, and transmission oil envelope Leakage is research topic in industry always.
Cause the inordinate wear that the main cause that transmission oil seals oil leakage fault is oil sealing, press-fit by force during oil sealing assembling,
Being press-fitted that not in place, assembly environment is unclean etc. all can lead to oil sealing flatness unqualified, thus causing oil sealing in use
Inordinate wear occurs, the using effect of impact speed changer even affects the security performance of automobile.
Therefore, accurately detect oil sealing flatness, reducing transmission oil envelope oil leakage fault is the problem that must solve.
Content of the invention
It is an object of the invention to provide a kind of structure is simple, easy to operate, can quick and precisely detect that speed changer oil sealing is put down
The detection means of face degree, can effectively solving transmission oil envelope Leakage.
To achieve these goals, the invention provides a kind of flatness checking device, for detecting speed changer oil sealing
Flatness, including detection platform, dial plate and rotary body, described rotary body be provided with probe it is characterised in that：Described dial plate includes
The disk that big dial plate and little dial plate, described detection platform and described big dial plate are formed in one, described little dial plate is arranged on described
Above big dial plate, described little dial plate is identical with the center of circle of described big dial plate.
The center of described detection platform is provided with the sleeve for fixing oil sealing to be detected.
Described rotary body has rotating shaft, and described rotating shaft is mobilizable to be arranged in described sleeve.
After described oil sealing is fixed in described detection platform, adjust described rotary body, make described probe and described oil sealing
Skeleton contacts.
Described dial plate is amesdial, and when probe is contacted with the skeleton of described oil sealing, the reference graduation of little dial plate is not for 1
～2, the reference graduation of big dial plate is 0.
Present invention also offers a kind of flatness detection method, comprise the steps：Step one：Band detection oil sealing is installed
On described flatness checking device, step 2：Adjust the reference graduation of the dial plate of described flatness checking device, little dial plate
Reference graduation is not zero, and the reference graduation of big dial plate is adjusted to zero, step 3：Rotary body rotation by described flatness checking device
Circle, judge whether the flatness of oil sealing to be detected is up to standard according to beating of dial scale.
Adjust the reference graduation of described dial plate, the reference graduation making described little dial plate is 1～2, the benchmark of described big dial plate
Scale is 0.
When the beating scope of described big dial scale is between 0-0.2mm, the flatness of described oil sealing is up to standard, when described
When the beating scope of big dial scale is more than 0.2mm, the flatness of described oil sealing is not up to standard.
The invention has the advantages that：Described flatness checking device is using double index dial structures with one heart, structure letter
Single, accuracy of detection is high, can quick and precisely detect speed changer oil sealing flatness；Described flatness detection method, easy and simple to handle, error
Little, can effectively solving transmission oil envelope Leakage.
Brief description
Fig. 1 is the schematic diagram of flatness checking device involved in the present invention.
Fig. 2 is the sectional view that flatness checking device involved in the present invention detects during oil sealing.
Specific embodiment
Come to flatness checking device involved in the present invention below in conjunction with Figure of description and specific embodiment
And detection method makes further explanation, but this explanation and illustrating do not constitute improper to technical solution of the present invention
Limit.
As shown in figure 1, the invention provides a kind of flatness checking device, including detection platform 1, dial plate and rotary body 4,
Rotary body 4 is provided with probe 5, and dial plate includes big dial plate 2 and little dial plate 3, the circle that detection platform 1 and big dial plate 2 are formed in one
Disk, little dial plate 3 is arranged on above big dial plate 2, and identical with the center of circle of big dial plate 2.
The center of detection platform 1 is provided with the sleeve 1.1 for fixing oil sealing to be detected.Rotary body 4 has rotating shaft
4.1, rotating shaft 4.1 is mobilizable to be arranged in sleeve 1.1.
As shown in Fig. 2 oil sealing is fixedly mounted in described detection platform 1, the lip 6.1 of oil sealing is down-set, adjustment rotation
The height of swivel 4, makes probe 5 and the rubber plane 6.3 on skeleton 6.2 top of oil sealing contact, for ensureing probe 5 and oil sealing bone
The rubber plane 6.3 of frame 6.2 completely attaches to, therefore when requiring probe 5 to contact with rubber plane 6.3, the scale of little dial plate 3 is to build
Discuss as 1～2, the scale of big dial plate 2 is zero.
Rotary body 4 is rotated a circle, even if probe 5 rubber planes 6.3 around oil tight skeleton 6.2 top rotate a circle, visits
5 fluctuate is beated display by the scale of big dial plate, if the scale beating scope of big dial plate 2 is between 0-0.2mm,
The flatness of described oil sealing is up to standard, otherwise then not up to standard.
It should be noted that the described above of disclosed embodiment enables professional and technical personnel in the field apparent
Ground carries out multiple being similar to for the present embodiment and changes and modifications, and this similar change is that those skilled in the art can be public from the present invention
The content opened immediately arrives at or is easy to all deformation just associated, and all should belong to protection scope of the present invention.Therefore originally
Invention will not be implemented by this.
