Description
Technical field
The utility model relates to a kind of measurer that is used for the processing of traction electric machine support, relates in particular to a kind of traction electric machine support and hangs the circular arc test measuring device.
Background technology
One section arc surface during hanging, the traction electric machine support is arranged; This is hung circular arc and hangs the bottom surface and hang seam all has status requirement; This is hung arc radius and also has tolerance simultaneously, detects accurately that to hang the radius of circular arc and hang circular arc be an important step in the support processing with the position relation of hanging.Shown in accompanying drawing 1, benchmark A and benchmark C are the seam of hanging of support, and its seam width is X+Y, and benchmark B is for hanging the bottom surface; The radius of hanging circular arc is R, hangs the distance of center circle of circular arc and hangs seam one end distance from being X (being Y apart from other end distance), is Z apart from hanging the bottom surface distance.The data that will detect after the support processing have the radius R of hanging circular arc, hang the distance X that the circular arc distance of center circle is hung seam one end, hang the circular arc distance of center circle hang the bottom surface apart from Z.
Existing detection technique mainly contains two kinds: one, use model to detect; Hang the position relation that arc surface and support hang seam and hang the bottom surface according to support and make model; The model profile is shown in accompanying drawing 2; Whether detect the support machined with model then, it is qualified to judge the position of hanging circular arc and hang the radius of circular arc; During use, only need model leaned against and hangs in the seam, through observing hanging circular arc and whether overlap on circular arc and the support on the model, whether position and the size that can judge arc surface on the support be correct; Two, use three coordinate measuring machine to detect.
It is not enough below yet present detection method exists: for model detects; Model is made by the radii size of hanging circular arc and circular arc and the relative position hung, and every kind of model can only be used for a kind of product, does not have versatility; Must make special-purpose model to different traction electric machines; And model can only make judgement to the arc surface after the processing is whether qualified, if arc surface size or malposition after the processing, model can not detect the size of arc surface position deviation and the size of arc radius deviation; So model detects and can not in process, use, and can not be used for process control; For the three-dimensional coordinates measurement machine testing, use the three-dimensional coordinates measurement machine testing not measure to the support of just on lathe, processing, need support be sent into the three-dimensional coordinates measurement chamber, after the measurement again the clamping support certainly will cause secondary clamping error.
Summary of the invention
