Description
Technical field
The present invention relates to a kind of survey instrument, particularly relate to a kind of survey instrument and measuring method thereof of spiral gear relative position angle.
Background technology
At present because client is to the needs of the technique of Product Assembly, propose there is angle requirement, so also propose new test item accordingly when component test to the relative position of the flat bit plane of the afterbody of kit gear and gear tooth slot.Because the flat bit plane of gear afterbody and gear tooth slot are at a distance of about 200mm, flat bit plane and teeth groove opening are in radial direction out of plumb, axial direction is also not parallel, and on the deflection instrument generally used, dial gauge measurement cannot be played again to teeth groove location, owing to adding man-hour at Hobbing by cutter quality, workpiece material, machine cut optimum configurations etc. affects occasional and adopts axial motion gear hob to ensure workpiece processing quality and to extend cutter life, again because lathe principle of work restriction each string cutter must cause the variation of gear tooth slot cut-out direction, thus cause the relative position angle of the flat bit plane of the afterbody of gear and gear tooth slot also to change, and after each debugging or string cutter, all want trial cut to cut could proofread several times to make the flat bit plane of gear afterbody and gear tooth slot relative position angle within margin tolerance, even so upper three-dimensional coordinate monitor station is also unrealistic, Positioning Gear is carried out because three-dimensional coordinate monitor station also needing multiple orientation tool, cumbersome and waste.Given this cubing of a kind of convenient and practical flat bit plane of prototype gear afterbody and gear tooth slot relative position angle will be designed.
