Description
Technical field
The present invention relates to paired journal box spring position of mounting hole degree flexible checking implement, for mounted in pairs on bogie
The position of mounting hole degree of journal box spring is detected.
Background technology
Journal box spring is the damping element using metal composites such as rubber and overcoat, dividing plate, mandrels, in train operation
During it is vertical play carrying, decay vibration, and transmit traction, brake load and lateral steering load, it is simple due to installing
Singly, conveniently, non-maintaining throughout one's life the characteristics of, is widely used in subway, light rail and low floor vehicle.Journal box spring is installed on track
On the bogie of car, as described in Figure 1, the outwardly shape of ears structure 101 in 100 bottom of journal box spring two is led to bogie frame
The cylindrical boss 102 crossed at the top of bolt fastening, mandrel is fastened by bolts with axle box.Each bogie installs a pair of axle boxes
Spring, a left member, a right member, left and right part is in addition to the outwardly shape of ears structure in bottom two is mirror, remaining structure, chi
It is very little identical.The screw thread of cylindrical boss end face at the top of the threaded mounting hole and mandrel of the outwardly shape of ears structure in bottom two
Whether position of mounting hole degree meets matching requirements, directly influences whether journal box spring can smoothly assemble.
In the prior art, special gauge not for journal box spring threaded mounting hole position degree.Three coordinates are used mostly
Detector is detected to journal box spring threaded mounting hole position degree, but the complex operation of three coordinate detectors, occupies space
Greatly, multiple mounting hole detections need to convert journal box spring placement direction, and labor intensity is high, and the measurement process used time, long efficiency was low, uncomfortable
For the continuous detection of batch.And three coordinate detection methods there are certain requirements to testing staff's skilled operation degree.
The content of the invention
There is provided one according to the position for the paired journal box spring mounting hole being arranged on bogie and characteristic distributions by the present invention
