On accurate junior machine, as KIC spark-erosion perforating machine, desk-top CNC machine etc., all have high precision primary spindle in main spindle box, main shaft one end inner conical surface with by the cylindrical that fills two groups of bearings, concentricity is high especially, the franchise of beating 0.005mm.A lot of enterprises were everlasting on horizontal V-shaped iron and measured its precision in the past, because inner hole of spindle is tapering, the very easy axial motion of rotating spindle when measuring, directly the precision of inner cone is measured in impact, the external diameter that small-sized main shaft is clamped by collet chuck or three-jaw by Ye You company checks, self error while turning round due to clamp body, the error of collet chuck itself, all can affect measuring accuracy.If upper three dimension coordinate measurement, because main shaft is little, inner cone is also little, may not necessarily correct measurement, and also cost is also large, looks into interrelated data, the detection tool not yet having had so far.
Utility model content
Technical problem to be solved in the utility model is to provide the cubing that the small-sized main shaft inner cone of a kind of precise engineering surveying is beated, utilize two wires one Points Location Law, the reference field of cubing is overlapped with small-sized main shaft drawing reference field, utilize small-sized main shaft self gravitation, slide to lower end limiting stand terrace, be subject to pressure beam to avoid vibration and swing, make to measure correct.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
The cubing that the small-sized main shaft inner cone of precise engineering surveying is beated, comprises cubing body, and described cubing body is provided with Weiα inclined-plane, pitch angle, and described inclined angle alpha equals the interior cone angle of 1/2 small-sized main shaft to be measured; On described inclined-plane, be provided with along its length for placing the V-type groove of small-sized main shaft to be measured, the end on described inclined-plane is provided with the limiting stand terrace that can place steel ball and cushion block.
The cubing that the small-sized main shaft inner cone of aforesaid a kind of precise engineering surveying is beated, is characterized in that: the bottom of described cubing body is reference field, is plane or sine gauge shape.
The cubing that the small-sized main shaft inner cone of aforesaid a kind of precise engineering surveying is beated, is characterized in that: the angle of described V-type groove is 90 °.
The beneficial effects of the utility model are: when utilizing cubing provided by the utility model to detect, tested small-sized main shaft is placed in the V-type groove with angle of inclination, V-type groove is on cubing body inclined-plane, primary spindle benchmark cylindrical is cut in the both ends of the surface of V-type groove, cubing body tail end is provided with limited step, mix high-accuracy steel ball and certain thickness cushion block, can be by vibration in the time of retraining little axle rotation; During measurement, rotary main shaft is flexible, does not swing not vibration, because the angle of inclination on cubing inclined-plane equals the interior cone angle of 1/2 small-sized main shaft to be measured, makes its inner conical surface element line horizontal, is difficult for causing error, and measuring accuracy can be controlled in 0.002mm.
