Description
Technical field
The utility model relates to the thickness of the rotor and stator of a kind of thickness detection apparatus more particularly to automobile current generator motor
Degree detection.
Background technique
The existing automobile motor rotor of industry and stator thickness measuring technique are surveyed by directly driving displacement sensor
Amount, contacts displacement sensor directly with workpiece surface certain point, to measure the general thickness size of workpiece.
Original motor rotor and stator thickness are such when measuring: displacement sensor is directly anchored in driving mechanism,
It follows driving mechanism to move up and down, is oriented to by line slide rail (shown in Fig. 1) and (prevents skew) effect.Work as driving mechanism
When operation, displacement sensor can be dropped to a certain fixed height, displacement sensor directly connects with workpiece surface certain point at this time
Touching, the overall thickness of workpiece entirety is assessed according to institute's measured data.
This kind of measurement method, due to keeping driving mechanism and displacement sensor directly fixed, so measurement numerical value receives driving
The influence of mechanism, and the method contacts displacement sensor directly with workpiece, can only measure the random certain point of workpiece surface
Dimension data, rather than data of overall dimension.
When the placement position of workpiece, when angle is inconsistent, measured data are different, therefore to the measurement environment of workpiece
It is required that high, anti-interference ability is weak.
Due to making displacement sensor directly and workpiece contact, when displacement sensor is contaminated, measurement data has larger inclined
Difference is unfavorable for being used for a long time.
In conclusion that there are measurement accuracy is low for the existing automobile motor rotor of industry and stator thickness measuring technique, to survey
Measure environmental requirement.
Utility model content
The utility model is intended to provide a kind of thickness detection apparatus, there is that " measurement accuracy is high, and strong antijamming capability uses the longevity
The characteristics of life length ", the overall size of workpiece can be accurately measured, influence of the driving mechanism to measurement accuracy is eliminated, passes through plane
Mechanism, solve measurement data is influenced by work status.
To solve the above problems, a kind of thickness detection apparatus provided by the utility model adopts the technical scheme that
A kind of thickness detection apparatus, including rack, measuring table, driving device, displacement sensor and moving guide rail；It is described
Measuring table is located at the lower section of the driving device, is fixedly connected with the driving device, while side and the shifting
Dynamic guide rail matches, and moves freely on the moving guide rail；The driving device is located in the rack, and described
Rack be fixedly connected；The moving guide rail is located at the side of the rack, is distributed along the vertical direction；The displacement passes
Sensor is located at the side of the moving guide rail, corresponding with the measuring table, is also secured to the moving guide rail
On.
Further, the measuring table is in horizontally disposed, with the driving device vertical distribution, is fixed on described
Driving device one end, remain horizontality.
Further, the driving device runs through the rack, and one end is fixedly connected with the measuring table, band
The measuring table is moved to move freely in the vertical direction.
Further, the moving guide rail is in contact with the side of the measuring table, is cooperatively connected, the survey
Amount platform moves freely in the vertical direction along the moving guide rail.
Further, the displacement sensor is fixed in the rack, measures the height of the measuring table
Size, i.e., the size of product to be measured.
The utility model has the beneficial effects that: a kind of thickness detection apparatus provided by the utility model, is thrown using one piece
Measurement plane and workpiece contact measurement after light, improve the stability of measurement；Displacement sensor is fixed, read measurement number
According to, it is ensured that the external disturbance being subject in measurement process reaches minimum；Guiding mechanism uses high-precision pre-profiling sliding rail, effectively
Improve the accuracy of measurement.
