Description
Technical field
The utility model relates to a kind of axle end face threaded hole position test measuring device, belongs to the field of quality check.
Background technology
The axletree that railway locomotive bogie uses is one of vitals of rolling stock EEF bogie, axletree both ends of the surface are all designed with three threaded holes, as shown in Figure 2, this threaded hole is used for installation shaft terminal bolt, by protecgulum, taper roll bearing end face is fixed on axle journal place.Axle end face three threaded hole position errors not only affect protecgulum and compress the state of bearing face and axletree and exchange with protecgulum and coordinate, and, when three threaded hole position deviations are larger, also have a strong impact on the fatigue strength of axle journal.
At present, traditional detection method is by detecting phase mutual edge distance between 3 holes as the foundation judging its position degree, accurately can not detecting, therefore cannot realize the preposition accurate detection before to Product Assembly, cause qualification rate during assembled product not high.
Utility model content
The object of the utility model device can not the accuracy of rigorous examination axletree three threaded hole positions in order to solve current method, provides a kind of axle end face threaded hole position test measuring device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of axle end face threaded hole position test measuring device of the present utility model, comprises measurer body, measurement column, guide pillar body and handle;
The front end of measurer body is plane of orientation, and this plane of orientation being vertically fixed with three measurement columns matched with axle end face to be measured three threaded hole distributing positions, the length of each measurement column and external diameter all match with the degree of depth of axle end face threaded hole and the minimal tolerance of internal diameter; The center of measurer body three measurement columns is processed with central through hole backward along the direction perpendicular to plane of orientation; Measurer body rear end outer wall inwardly has the threaded hole be communicated with central through hole;
The leading portion of guide pillar body is processed with the conical section that in profile and axle end face center pit to be measured, shape matches; The back segment of guide pillar body is processed with the cylindrical section matched with measurer body central through hole internal diameter, and the side-wall shaft of this cylindrical section is to having spacing elongated slot; The rear end end face of guide pillar body has threaded connection hole;
In the guide pillar body conical section central through hole that insertion is concrete forward, stop screw inserts in the spacing elongated slot of guide pillar body cylindrical section sidewall through the threaded hole of the external wall of measurer, makes guide pillar body and measurer body axial limiting; Stop screw spacing under, the shortest length of the concrete plane of orientation of guide pillar body front end overhang and the degree of depth of axle end face center pit to be measured match; The rear end end-face helical connecting handle of guide pillar body.
The course of work
During detection, hold handle and insert in axle end face center pit to be measured completely by guide pillar body leading portion, amount of spin specifically makes three measurement columns aim at three threaded holes of axle end face to be measured respectively; While keeping guide pillar body leading portion to insert axle end face center pit to be measured completely, stirring forward measurer body is again pressed in three threaded holes of axle end face to be measured by three measurement columns, if the plane of orientation of measurer body front end can contact with axletree front end face to be measured, then illustrate that this axletree product to be measured is qualified, otherwise defective.
Beneficial effect
Test measuring device structure of the present utility model is simple, easy to operate, efficiently solves a difficult problem for inspection position of end threaded hole of axle shaft, ensure that the precision of inspection, saving the speed that labour intensity improves inspection, improve production efficiency, meeting the group of batch production to requiring.

Wherein, 1-handle, 2-guide pillar body, 3-measurer body, 4-measurement column.
Embodiment
Below in conjunction with drawings and Examples, content of the present utility model is further described.
Embodiment
The verifying attachment of a kind of position of end threaded hole of axle shaft of the present utility model, as shown in Figure 2, comprises measurer body 3, measurement column 4, guide pillar body 2 and handle 1;
The front end of measurer body 3 is plane of orientation, and this plane of orientation being vertically fixed with three measurement columns matched with axle end face to be measured three threaded hole distributing positions, the length of each measurement column and external diameter all match with the degree of depth of axle end face threaded hole and the minimal tolerance of internal diameter; The center of measurer body 3 three measurement columns is processed with central through hole backward along the direction perpendicular to plane of orientation; Measurer body 3 rear end outer wall inwardly has the threaded hole be communicated with central through hole;
The leading portion of guide pillar body 2 is processed with the conical section that in profile and axle end face center pit to be measured, shape matches; The back segment of guide pillar body 2 is processed with the cylindrical section matched with measurer body 3 central through hole internal diameter, and the side-wall shaft of this cylindrical section is to having spacing elongated slot; The rear end end face of guide pillar body 2 has threaded connection hole;
In the central through hole of guide pillar body 2 conical section insertion concrete 3 forward, stop screw inserts in the spacing elongated slot of guide pillar body 2 cylindrical section sidewall through the threaded hole of measurer body 3 outer wall, makes guide pillar body 2 and measurer body 3 axial limiting; Stop screw spacing under, the shortest length of concrete 3 plane of orientations of guide pillar body 2 front end overhang and the degree of depth of axle end face center pit to be measured match; The rear end end-face helical connecting handle of guide pillar body 2.
The course of work
During detection, hold handle 1 and insert in axle end face center pit to be measured completely by guide pillar body 2 leading portion, amount of spin concrete 3 makes three measurement columns aim at three threaded holes of axle end face to be measured respectively; While keeping guide pillar body 2 leading portion to insert axle end face center pit to be measured completely, stirring forward measurer body 3 is again pressed in three threaded holes of axle end face to be measured by three measurement columns, if the plane of orientation of measurer body front end can contact with axletree front end face to be measured, then illustrate that this axletree product to be measured is qualified, otherwise defective.
