The transition hitch is the coupling arrangement that is used for the train loopback and rescues, and the transition coupler body then is to constitute transition hitch basic component, and the coupler knuckle chamber of its convex cone portion is shaped as semi arch, and the inner space is semi-closed structure.Circular arc centre point position is coupler body joint face and coupler body center line intersection in the coupler knuckle chamber.The circular arc method is to adopt general gauge (like vernier height gauge) or three-dimensional coordinates measurement in the existing measurement coupler knuckle chamber, and these two kinds of measuring methods not only can not satisfy on-the-spot detection requirement, and detection efficiency is lower.
Summary of the invention
The object of the present invention is to provide the transition coupler body coupler knuckle chamber inner arc radius that a kind of measuring speed is fast, efficient is high to measure appliance special for detecting.
In order to achieve the above object; Technical scheme of the present invention is: a kind of transition coupler body coupler knuckle chamber inner arc radius is measured appliance special for detecting, comprises the cubing body, measures mandrel, dial gauge, holding screw, lengthening gauge head, and said cubing body has first working plate and second working plate; The workplace of first working plate is vertical each other with the workplace of second working plate; First working plate is provided with the alignment surface that is used to calibrate the dial gauge zero-bit, and first working plate and the second working plate intersection are provided with axle sleeve, measures mandrel and axle sleeve clearance fit; Measure the mandrel middle part and have radial direction through hole and threaded hole; The gauge head retained part of dial gauge is inserted in the radial direction through hole, and the lengthening gauge head is connected on the gauge head retained part of dial gauge, and the gauge head retained part that holding screw is screwed into threaded hole and its end and dial gauge offsets.
One end of said measurement mandrel has handle.
Said axle sleeve has two, lays respectively at the two ends of first working plate and the second working plate intersection, and two axle sleeves keep coaxial.
Said first working plate has the first square opening, and second working plate has the second square opening.
Be provided with reinforcement between said first working plate and second working plate.
After adopting said structure, can make and measure the intersection point that mandrel is centered close to coupler body joint face and coupler body center line, realize that location and measuring basis overlap; Adopt the comparative method for measuring principle, utilize dial gauge directly to read the radius value of circular arc in the coupler knuckle chamber, therefore; The present invention can measure the physical size of circular arc in the coupler knuckle chamber exactly; Improved accuracy of detection and detection speed, efficient is high, has satisfied the needs that operation is measured well.
