Description of drawings
Fig. 1 is non-spherical measuring instrument structural representation.
Embodiment
The utility model proposes a kind of non-spherical measuring instrument, this non-spherical measuring instrument is the contact type measurement machine, mainly is comprised of air-float turntable, air supporting crossbeam, displacement and angular adjustment apparatus and pedestal four parts.Below in conjunction with accompanying drawing the utility model is explained.
In non-spherical measuring instrument structural representation shown in Figure 1, pedestal 5 is placed on the steelframe 7 with four castors 6, at the table top left side of pedestal 5 fixed air floating turntable 1, and air-float turntable 1 fixed angle adjusting gear 3; At the table top right side of pedestal 5 arranged in dislocation air supporting crossbeam 2 and Adjustment of displacement guide rail 4, at Adjustment of displacement guide rail 4 near the fixing contact measuring head 8 of angular adjustment apparatus 3 one ends, the fixing Y-direction adjustment handle 9 in air supporting crossbeam front.Wherein, air-float turntable 1 selects noble and unsullied gas for supporting, and has C s function and very high rotating accuracy, provides assurance for detecting workpiece accuracy.
Air supporting crossbeam 2 selects noble and unsullied gas for supporting, because be furnished with the open grating scale of high precision in the side of contact measuring head 8, so can guarantee high position precision and repetitive positioning accuracy.
Displacement and angular adjustment apparatus are realized by air supporting crossbeam 2 and Adjustment of displacement guide rail 4, air-float turntable 1 and angular adjustment apparatus 3; Displacement adjusting device is the duralumin Precision Machining, and surperficial white anodic oxidation adopts high precision intersection spherical guide to connect between air supporting crossbeam and the Adjustment of displacement guide rail, increased load-bearing capacity and life-span; Adjustment of displacement is that the micrometer head driving spring resets, and eliminates end play.Angular setting is the duralumin Precision Machining, surperficial white anodic oxidation.Adopt the adjustable dovetail guide of lappingout, precision is high, and carrying is large.Worm gear pair drives, and it is comfortable to move, and is accurate reliable, and adopts high-accuracy contact measuring head, reduced owing to measure the error of bringing.
Pedestal 5 is placed on the steelframe 7 with four castors 6, and pedestal 5 is made by natural granite.Use the overall flexibility that castor supports has increased non-ball measuring instrument; Steelframe connects castor and natural granite, has increased the rigidity of non-ball measuring instrument integral body with stable; Natural granite is through long-term seasoning, and institutional framework is even, and linear expansion coefficient is minimum, the internal stress complete obiteration, indeformable. good rigidly, hardness is high, wearing quality is strong, and temperature deformation is little. and have good effect in acid, the alkali lye thing corrodes, can not get rusty, needn't oiling, be difficult for sticking micronic dust, safeguard that easy maintenance is simple, long service life. the crystal grain that the is impacted surperficial phozy limit that comes off does not affect its plane precision, its working surface in use maintenance is easy, and stable material quality can guarantee the shape that remains unchanged for a long period of time.
Principle of operation: first Y-direction is adjusted handle 9 and is adjusted the Y-direction position, make axis of movement and air-float turntable 1 axes intersect of air supporting crossbeam 2, again workpiece is placed on the tray for work pieces that angular adjustment apparatus 3 places above, by adjusting displacement and angular adjustment apparatus 3 adjustment workpiece and air-float turntable 1 relative positions.Measuring head 8 is adjusted the position in Z-direction, air-float turntable 1 carry out C to motion, air supporting crossbeam 2 in X-direction motion, Computer Processing measurement data.
