Description
Technical field
The utility model relates to field of automobile, especially a kind of automobile transmission rack sensor measurement dress
It sets.
Background technique
In automobile manufacturing field, online NVH detection can be all carried out when automotive transmission is finally offline, this detection is to pass through
Sensor is closely fitted in the detection data that needs are obtained on case of transmission by rubber, and the tightness degree of fitting directly affects
The accuracy of test, so the decrement of rubber is the critical quantity of a detection；Since rubber is a kind of easily-deformable plasticity material
Material, so, it may cause the inadequate situation of decrement in the actual operation process, therefore, it is detected；Existing inspection
Survey method is mostly to complete measurement by ruler and set square by testing staff, and since operating space is limited, test is very inconvenient,
Be not time of measuring length be exactly measurement data inaccuracy, influence measurement result.
Summary of the invention
The purpose of the utility model is to provide a kind of automobile transmission rack sensor surveying units, it can solve at present
The problem of online NVH detection operation time of measuring of speed changer is long, measurement data is inaccurate, influences measurement result.
To solve the above-mentioned problems, the technical solution adopted in the utility model is: this automobile transmission rack sensor
Measuring device, has a gauge rod, and one end of the gauge rod connects the measurement plate of a vertical bands through slot, institute by clamp device
Gauge rod setting is stated in a reeded main body of tool, the main body is equipped with the first through slot, is equipped with sensing in first through slot
Device protective cover, the sensor protective cover are fixedly connected with a bracket, and the bracket connects a rubber bar, the rubber bar
Vibrating sensor is connected, the bracket is also connected with a driving device；The main body is additionally provided with the second through slot, second through slot
It is interior equipped with the pointer being connect with the gauge rod.
In above technical scheme, further scheme may is that the measurement plate is plate structure, and head is equipped with measurement
Head, middle part are equipped with the through slot that width is less than the gauge rod cross-section width dimension.
Further: the cross-sectional shape of the groove of the main body is dove tail shape, described second in the main body
The lower section of through slot is equipped with scale.
Further: the cross sectional shape of the sensor protective cover is 7 fonts.
Further: the driving device is cylinder, and there are two the cylinders, is arranged side by side, the bracket is connected to institute
State the extension end of cylinder.
Further: the clamp device is wing bolt.
By adopting the above-described technical solution, the utility model has the following beneficial effects: compared with prior art
The utility model is the auxiliary mould for the offline NVH vibrating sensor compression measurement of speed changer, is split type
Structure, easy to carry, installation and dismantling；Measuring head is connect by wing bolt with gauge rod, and gauge rod is by dovetail groove and measures this
Body connects, and level trough is provided on ontology and is connected for sensor protective cover, the opposite position of adjustment measuring head and sensor is not only conducive to
It sets, moreover it is possible to mitigate tooling weight, in the narrow test environment of checking table, simply accurately be quickly obtained sensor decrement data；
Ensure that vibrating sensor is under service pressure, ensures the authenticity of DATA REASONING.
