Description
Technical field
The present invention relates to automobile mechanical field, in particular to a kind of automobile mechanical axial workpiece roundness quickly detects dress
It sets.
Background technique
In automobile mechanical product, axial workpiece is generally existing.Axial workpiece is the typical case frequently encountered in Hardware fitting
One of part, it is mainly used to bearing transmission components, transmitting torque and receiving load, different by axial workpiece structure type,
It generally can be divided into optical axis, multi-diameter shaft and special-shaped axis three classes；Or be divided into solid shafting, hollow shaft etc..
Circularity contains the difference of the radius of same cross section actual profile and semidiameter between the smallest two concentric circles.
The assessment method of deviation from circular from has 4 kinds: least envelope zone method, minimum circumscribed circle method, Maximum Inscribed Circle Method are minimum
Square law.It is very popular for a long time since least square method is simple and easy to do.Though there are many methods for measuring deviation from circular from,
The most reasonable, with the most use is radius method.For this purpose, being surveyed on optical dividing head with amesdial by using radius measurement method
Deviation from circular from is measured, and least square method calculating is carried out to measurement data, in the hope of roundness error.When measurement, by measured work
Part withstands on two top of optical dividing head, and dial gauge is placed on measured cross section, measures the variation delta r of its radius,
Tested circumference is divided into n measurement point using optical dividing head, when often turning over θ=360 °/angle n, from dial gauge
Deviation Δ r of this relative to certain Radius R0 is read, all data Δ ri are thus measured.
Automobile axial workpiece is if there is error, it will the operation of vehicle is seriously affected, to cause danger, to roundness
The method of detection is varied, has revolution method of principal axes, line-of-sight course, two-point method, sciagraphy and coordinate method etc., also some is adopted using data
Collect instrument and connect dial gauge method, but need to be measured in combination using the inclined instrument of pendulum and data collecting instrument when measurement, needs
Data analysis is carried out, while equipment is more accurate, and also inconvenience repairs when damage, increases use cost, is measuring
When roundness, inconvenience is intuitively observed, device also when in use, it is inconvenient at the same to the roundness of multiple axis classes into
Row detection, to reduce detection speed.

It is bright that discharge port plate is targetedly arranged, be on the one hand conducive to be more easily aligned when plasticine squeezes out in this way, on the other hand
Also improve the reliability of equipment.
Preferably, the helical spring is fixedly connected with lantern ring and bottom plate respectively.
Compared with prior art, the beneficial effects of the present invention are:
1, the present invention passes through support rod to the guiding of lantern ring, in conjunction with helical spring, to conveniently slide up and down to casing, side
Just roundness detection is carried out to the different location of axial workpiece；
2, by the setting of extension airbag, so as to which plasticine is added in extension airbag, by plasticine in axis class
The thickness of part is intuitively observed so as to the roundness to axial workpiece, thus the convenient roundness to axial workpiece
It is used for quickly detecting, and facilitates observation, avoid and calculated using excessive data, reduce cumbersome operation, to use
Person provides convenience；
3, by the sliding between conduit and fixing pipe, the position of discharge port plate can be adjusted, thus fast and easy
Coating is carried out to Axle Surface, while also facilitating and quickly removing axial workpiece, convenient for being detected to axial workpiece；
4, by 4 positioning pipes of setting, so as to allow multiple people to detect simultaneously to multiple axial workpieces, thus plus
The fast detection speed to axial workpiece, while also avoiding not inconvenient enough the difficulty to the detection of multiple axial workpieces of work space
Topic, and structure is simple, reasonable design, easy operation facilitates and is intuitively observed.
