Description
Technical field
The utility model is related to a kind of devices of detection axis transverse plane rectangular channel symmetry.
Background technology
In machine-building, symmetry refers to using benchmark as symmetrical centre, symmetrical plane or axle center comprising measured surface
Minimum range between two planes of line, belongs to the position error in site error.Have face-to-face, in face of line, Line To Line, line
The symmetry on opposite.Tolerance range be distance for tolerance value t, and relative datum central plane（Center line, axis）Balanced configuration
Two regions between plane or straight line.Symmetry is to control central plane or center between element to be measured and reference element
The coplanar or linear requirements of line, axis.Symmetry error is due to being tested central factor, and central plane, axis are relative to benchmark
Central factor（Central plane, axis）Caused by translation occurs or tilts or haves both at the same time.Rectangular channel or keyway are in machinery on axis
Use widely in structure.Incline since the practical center plane of rectangular channel or keyway generates offset and axial generation in radial direction
Tiltedly, the symmetry error of rectangular channel or keyway is caused.Rectangular channel or keyway symmetry are that influence to couple one is important on axis
Parameter directly affects transmission of the transmission component to torque and movement, and then affects precision and the service life of whole equipment.Due to
On axis there is the reason of processing, clamping, lathe equal error in rectangular channel or keyway, and directly detection rectangular channel symmetry is relatively difficult,
Two plane of rectangular channel is difficult that completely opposite center reference plane is symmetrical.Commonly used in axis and parts on shaft, as gear, belt pulley,
Connection between shaft coupling etc. is used for transmitting torque and movement, plays rectangle on axially directed axis in driving parts on axis
Slot or keyway, shaft coupling and output shaft combination output torque, they are realized by rectangular channel or key connecting.Key and keyway
Using basic shaft system, different fiting property requirements is realized by changing the tolerance range of keyway for cooperation.Rectangular spline rectangular channel
Or detection include dimension control and Form and position error and examine.In production, generally using the general metering such as vernier caliper, micrometer
Utensil is to key rectangular channel or measures.In single-piece, small lot production, the detection of rectangular channel or width of keyway and depth is general
It is examined with general measurer, and in mass production, it commonly uses dedicated gauge and examines size.In single-piece, small lot production, square
The symmetry project of shape slot or keyway is generally detected using general measurer；And when producing in enormous quantities, mostly using private volumn
Advise the symmetry error to examine keyway.In order to detect the practical symmetry size of rectangular channel, there are many squares in detection axis
The method of shape slot or keyway, but existing method is mostly passive, indirectly.In order to realize from measuring direct measurement indirectly, from
The transformation that passive measurement is measured to active, the prior art devise rectangular channel or keyway symmetry special vernier caliper on a kind of axis
Digital display axis on keyway symmetry detection ruler.This measurement cannot measure specific error amount, and measure and can only process
After carry out, belong to passive measurement, therefore be merely able to waste product removing, without being avoided that waste product, do not have directive significance to processing.Such as use
Tablet, locating piece, dividing head, the measurement bay mensuration with indicator need to turn workpiece and centering repeatedly, complicated for operation, so
Measured value substitution formula is calculated afterwards, belongs to and measuring indirectly, and the accuracy measured indirectly will depend on related parameter measurement
Accuracy, and calculation formula is related with based on.The utility model provides a kind of rectangular channel symmetric degree detecting mechanism.It should
Mechanism is applied to such as the detection of 5 rectangular channel symmetry of tested part in Fig. 1.
