Description
Technical field
The present invention relates to a kind of measurer, especially a kind of improvement structure of slide calliper rule.
Background technology
Slide calliper rule class survey instruments such as existing vernier caliper, height gauge are not because measurement face overlaps with the reference measurement axis, the side direction tolerance clearance of blade and chi frame has had a strong impact on the accuracy of measurement result.As shown in Figure 1,02 tolerance clearance of blade 01, chi frame of survey instruments such as slide calliper rule in the market, height gauge is generally adjusted by front and back holding screw 04 on the chi frame, be applied to pressure on the flexural spring sheet 03 by adjusting holding screw, guarantee that blade slides along chi frame reference field, thus the control sideshake.But there is following problem in use in these class slide calliper rule: (1) is in manufacture process, because the restriction of manufacturing process is difficult to guarantee that the width consistance of blade is definitely good, adjusts by width point, and then the narrowest place is must the gap bigger, less than accomplishing the zero stand-off; (2) in assembling process, the adjustment of holding screw is not in place or in use holding screw is loosening, makes the pressure imbalance at the too small or spring leaf two ends of spring leaf pressure, all can cause the variation of sideshake; (3) as shown in Figure 2, in the measuring process,, can cause the laterally offset of chi frame, the gap between chi frame and blade is increased, influence measurement result if measured object is excessive so that when having overcome spring leaf to the pressure of blade to the reacting force of chi frame.Therefore the measurement of slide calliper rule does not generally all meet abbe ' s principle, and the problems referred to above need the slide calliper rule structure further to improve, and to obtain higher measuring accuracy even to eliminate the error that this measuring principle aspect produces, satisfies the needs that people use better.
Summary of the invention
