Description
Technical field
The utility model belongs to survey tool technical field, and in particular to a kind of frame level of accurate zeroing.
Background technology
The levelling tube of level meter is made up of glass, and level inside pipe wall is a curved surface with certain curvature radius, in pipe
Equipped with liquid, when level meter run-off the straight, bubble just moves to the elevated one end of level meter in levelling tube, so that it is determined that horizontal
The position in face.Level inside pipe wall radius of curvature is bigger, and resolution ratio is higher, and radius of curvature is smaller, and resolution ratio is lower, therefore level
Pipe radius of curvature determines the precision of level meter.Level meter be mainly used in examining the flatness of various lathes and workpiece, linearity,
Perpendicularity and the horizontal level of equipment installation etc..
Easy to use due to the simple structure of level meter, therefore, level meter is most base in Machine Manufacture, installation and repairing
A kind of this instruments of inspection.Examine plane to the deviation of horizontally or vertically position before, it is necessary to water using frame level
The zero-bit of level is checked or adjusted, and avoids the measurement error caused by level meter zero-bit is inaccurate.
Such as notification number CN202420484U Chinese utility model patent discloses a kind of multifunction frame type level meter, bag
Level body is included, transverse bubble is designed with level body, longitudinal level and circle are also devised with level body
Shape spirit level, universal level include universal level body, instruction bubble, circular level are designed with universal level body
Circular scale line and angle index line are also devised with device body, circular scale line and angle index line intersect, level body
Side on be respectively designed with outside cylinder axial location measuring surface, interior cylinder axis position measurement face and horizontal departure measuring surface.
It is seen that a kind of multifunction frame type level meter of the prior art, by set on level body universal level and
Longitudinal level improves the measurement accuracy of the multifunction frame type level meter of the prior art, but have ignored described all water
Whether quasi- device itself ensure that higher levelness in horizontal level, and this can directly influence the frame water of the prior art
The measurement result of level.
