Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Large scale outside micrometer of the invention is to zero branch stake tool, as shown in Figure 1, including supporting mechanism and supporting block
1, the supporting mechanism includes pedestal 2, upright bar 3 and height adjustment mechanism, and the lower end of the upright bar 3 is fixed on pedestal 2, institute
It states height adjustment mechanism to be mounted in upright bar 3, the supporting block 1 is fixedly connected with height adjustment mechanism, and is arranged in supporting block 1
There is the V-shaped groove 12 of notch upward, the angle of two cell walls of V-shaped groove 12 is 90 degree.
The bottom surface of pedestal 2 is horizontal, can be stably placed on horizontal plane, plays the role of supporting whole device.Upright bar 3
For vertical rod piece, play the role of guiding and bearing height regulating mechanism.Supporting block 1 is for placing diameter micrometer
Check and correction gauge rod, gauge rod is placed in V-shaped groove 12, using steadily of centre of gravity principle, is positioned by V-shaped groove 12 to gauge rod.Highly
Regulating mechanism is used to adjust the height of supporting block 1, so that gauge rod be made to be located at suitable height.
In use, multiple branch stake tools of the present invention are in a row placed on horizontal ground or table top, multiple supports are adjusted
Then gauge rod is placed on the V-shaped groove of the supporting block 1 of each stake tool to suitable position by the height of the height adjustment mechanism of tool
In 12, then finely tuning keeps gauge rod holding horizontal.
The pedestal 2 of supporting mechanism can be steel plate, iron block etc., and upright bar 3 can be steel pipe, rod iron, rectangular shaft etc., as excellent
The technical solution of choosing: the supporting mechanism is vernier height slide calliper rule, and pedestal 2 is the support of vernier height slide calliper rule, and upright bar 3 is vernier
The main scale of height calipers, height adjustment mechanism are the vernier scale 4 of vernier height slide calliper rule.Vernier height slide calliper rule are existing standard
Change, the measurer of mass production, small in size, light-weight, easily worn part replacement is convenient, simple refit after can directly buying
It uses, design, manufacturing cost has been saved, and the interchangeablity of different vernier height slide calliper rule is strong, in order to later maintenance.This
Outside, vernier height slide calliper rule can precisely adjust the height of vernier scale 4 as measurer, precision with higher itself by reading
Degree to guarantee the position precision of gauge rod, and then improves the accuracy calibrated to zero error and the entire error of indication.
The vernier scale 4 includes sliding shoe 41 and positioning beam 42, and the sliding shoe 41 is slidably matched with main scale, the branch
Bracer 1 is removably mounted to positioning beam 42.Vernier scale 4 improves on the basis of existing, and sliding shoe 41 remains unchanged, with master
Scale is slidably matched and is fixed on main scale by fastening screw.Positioning beam 42 carries out on the basis of ruler is fixedly mounted originally
It truncates, improves the stability of support.
Supporting block 1 can be fixed in positioning beam 42 by existing various mounting means, it is preferred that the supporting block 1
It is installed on positioning beam 42 by screw 44, can rapidly dismount supporting block 1, in order to replace different supporting blocks 1.Specifically
Ground, the bottom of the supporting block 1 are provided with positioning plate 11, and the bottom of the positioning beam 42 is fixed with positioning sleeve 43, described fixed
Position plate 11 is inserted into positioning sleeve 43 and is pressed abd fixed in positioning sleeve 43 by screw 44.
Two cell walls of V-shaped groove 12 can be smooth plane, as a preferred technical scheme: as shown in Figures 2 and 3,
Be provided with the support rim 13 of V-arrangement on 12 cell wall of V-shaped groove, the section of the support rim 13 is in isosceles trapezoid, and waist with
Angle between bottom is 45 degree, and the width at 13 top of support rim is less than the width of 12 cell wall of V-shaped groove, 13 bottom of support rim
Width be equal to 12 cell wall of V-shaped groove width.By the way that support rim 13 is arranged on 12 cell wall of V-shaped groove, support is utilized when use
Boss 13 supports gauge rod, and the top surface of support rim 13 is the supporting surface for supporting gauge rod, and the width of the supporting surface is smaller, is designed as
The contact area of 1mm or so, supporting surface and gauge rod is small, can be with obvious earth's surface when gauge rod is not completely attached to supporting surface
Reveal and, be easy to find and be adjusted, guarantees the levelness of gauge rod, and then guarantee calibration accuracy.
Large scale outside micrometer of the invention has the advantage that zero branch stake tool
1, at low cost, a set of stake tool cost only several hundred members, but for assay calibration large scale outside micrometer
Thousands of sets；
2, part replacement is convenient, which is that vernier height slide calliper rule are restructured, and most of is standard component, only
Supporting block 1 is workpiece, and workpiece design is simple, easy processing, and replacement is convenient；
3, it is easily understood using principle, is easy to operate, operator can grasp user by short time simple training
Method and skill；
4, influence of the human factor in calibration is reduced, is guaranteed to the gentle support of gauge rod, is improved to zero error and whole
The accuracy of a error of indication calibration.
