Description
Technical field
The present invention relates to a kind of oil seal seat crudy detection technique, more particularly to one kind to be used to detect oil seal seat processing matter
The method of amount.
Background technology
The oil seal seat used on heavy-duty vehicle bridge input shaft on oil seal seat as shown in figure 1, be used for setting rotary shaft lip type
As shown in mark 11 in figure, the position is designated as detection zone at the position of sealing ring；In order that rotary shaft lip seal circle can reach
Preferable sealing effectiveness, when processing oil seal seat, in addition to being had higher requirements to the cylindricity of detection zone and roughness, also require
Detection zone process without helical grinding, to ensure detection zone surface without screw type texture；During actual processing, as long as strictly pressing
Processed according to drawing, the cylindricity and roughness of detection zone can generally meet to require, only without screw type texture this requirement not
The wheel face shape that the reason for readily satisfying, causing this problem is likely to be processing is improper, it is also possible to is to add
Work process medium plain emery wheel has axial displacement, or is that emery wheel feed amount is excessive etc., in a word, causes detection zone surface spiral to be present
The factor of type texture is a lot, it is impossible to investigates one by one in process；All meet the oil of requirement for cylindricity and roughness
Seal for seat, the screw type texture on its detection zone surface is generally very slight, only according to being visually difficult to distinguish, if with professional electricity
Sub- microscopy apparatus is detected, although it can be found that problem, this detection mode operation is cumbersome, and efficiency is low, to behaviour
The professional skill for making personnel requires higher, and in actual production, it is also not possible to the Electron Microscopy of precision is arranged on machine
In processing site, do not possess the feasibility for daily production；If the oil seal seat that surface has screw type texture is made by entrucking
With, be not in problem when just starting, but using may result in rotary shaft lip seal circle seal failure after a period of time, at this moment
Problem investigation is carried out to vehicle again and maintenance, cost are all larger.
The content of the invention
The problem of in background technology, the present invention propose a kind of method for detecting oil seal seat crudy, oil
It is used to set the region of rotary shaft lip seal circle to be designated as detection zone on envelope seat outer peripheral face, involved hardware includes being used to detect
The device of oil seal seat crudy, described device by base, two thimble supports, two thimbles, mandrel, lock sleeve, motor,

It is axial axially in parallel with the guide rail, and two thimbles are coaxial, the tip of two thimbles is relative；The end face at the mandrel both ends
On be provided with the groove matched with the tip, be provided with limited step in the middle part of mandrel, be provided with the left of limited step and oil
The spline segment of the internal spline matching of seat is sealed, the thread segment matched with lock sleeve, the right side of limited step are provided with the left of spline segment
Side is provided with the transmission segment matched with transmission belt；The tip of the thimble is pushed against in the groove, two thimbles respectively with core
Axle both ends are corresponding, and oil seal seat is socketed on the spline segment of mandrel, and lock sleeve is threadedly coupled with the thread segment of mandrel, and lock sleeve is by oil
Envelope seat is pushed against on limited step；The motor is arranged on base, and the output shaft of motor passes through transmission belt and mandrel
Transmission segment is connected；The fine rule ring pine is enclosed on detection zone, and counterweight is connected with fine rule ring and dropped naturally；Its feature exists
In：Methods described includes：
1) oil seal seat to be detected is arranged on mandrel, manual actuation oil seal seat rotates some circles, then treats oil seal seat
Naturally it is static, after oil sealing dwell of sley, the current location of fine rule ring is marked on detection zone with marking pen, obtains mark one；
2) motor is started, drive mandrel rotates forward, and rotating speed is 30~40 circles/minute, rotational time more than 20 seconds；Rotation
Turn after the time terminates, to treat that oil seal seat is naturally static, after oil sealing dwell of sley, examined the current location mark of fine rule ring with marking pen
Survey in area, obtain mark two；The vertical distance of mark one and mark two is measured, the vertical distance of mark one and mark two
Distance one is designated as, if distance one is more than 2.5mm, it is substandard product to illustrate oil seal seat, and oil seal seat is pulled down and re-starts table
Face is handled；If distance one is less than 2.5mm, into step 3)；
3) motor is started, drive mandrel reversely rotates, and rotating speed is 30~40 circles/minute, rotational time more than 20 seconds；Rotation
Turn after the time terminates, to treat that oil seal seat is naturally static, after oil sealing dwell of sley, examined the current location mark of fine rule ring with marking pen
Survey in area, obtain mark three；The vertical distance of mark two and mark three is measured, the vertical distance of mark two and mark three
Distance two is designated as, if distance two is more than 2.5mm, it is substandard product to illustrate oil seal seat, and oil seal seat is pulled down and re-starts table
Face is handled；If distance two is less than 2.5mm, illustrate that oil seal seat processing is qualified.
The present invention principle be：Under the Action of Gravity Field of counterweight, fine rule ring is tensioned, fine rule ring and detection zone after tensioning
Intimate surface contact, due to fine rule ring and detection zone intimate surface contact, when detection zone rotates, if detection zone surface has spiral shell
Rotation type texture, screw type texture will play guide effect to fine rule ring, make fine rule ring that axial displacement occur, if screw type texture
More serious, the displacement of fine rule ring is with regard to larger, if screw type texture is more slight, the displacement of fine rule ring is just smaller, if not
Screw type texture be present, then fine rule ring would not be subjected to displacement, then our cans by measure the displacement of fine rule ring come
Determine whether the order of severity of screw type texture and screw type texture, and then us the crudy to detection zone is made
Go out to judge, finally avoid underproof oil seal seat from being used by entrucking.
The method have the benefit that：Propose a kind of method for detecting oil seal seat crudy, this method
Used apparatus structure is simple and convenient to operate, and detection is simple to operate, efficient, it is not necessary to which operating personnel have higher specialty
Technical ability, detection operation can be implemented at any time, be very suitable in production process carrying out real-time quality testing to product.
