Abstract
The utility model relates to an arc inner circle radius measuring instrument with simpler structure, more convenient operation and more accurate measure. One main ruler and a secondary ruler are matched in use, and the main ruler is perpendicular to the secondary ruler. Two contact pins are respectively moved on the secondary ruler to select the same scale and read (x value), and then the main ruler moves up and down to read (a value). Also a vernier can be increased to read more accurately. The corresponding reading results are substituted into the equation: r = (x<2> is multiplied by a<2>) / 2a, and then the result can be calculated or the value can be directly read by a displacement sensor and a digital display device.
Description
Affiliated technical field
The utility model relates to a kind of device of measuring radius of circle in the circular arc.
Background technology
At present, radius of circle measuring instrument structure is made up of a main scale and several secondary chis or main scale, secondary chi and slave part or protractor, ruler and rotating shaft etc. in the known circular arc, complex structure, heaviness, unreasonable, be inconvenient to operate, limited more accurate measurement result, and be inconvenient to carry and be inconvenient to and make.
Summary of the invention
For the deficiency that overcomes that radius of circle measuring instrument in the existing circular arc is inconvenient to operate, carry and can't produce in batches with standard component, the utility model provides radius of circle measuring instrument in a kind of circular arc, the radius of circle measuring instrument is not only simple in structure, easy to operate in this circular arc, and can more accurate measurement.
The technical scheme that its technical matters that solves the utility model adopts is: radius of circle measuring instrument in a kind of circular arc, two haptic elements are worn about respectively and are hung on secondary chi, the master calibration chi is worn up and down by fixing rib and is hung on secondary chi, its primary structure is: but two haptic elements wear about respectively and be hung on secondary chi and move left and right, have the master calibration chi of haptic element to wear to be hung on secondary chi and can move up and down
The contact pilotage of two haptic elements is flat flat pin, and contact pilotage slopes inwardly, and contact pilotage is individually fixed on two haptic elements by fastening bolt 7, and two haptic elements are fixed in by nibbed screw in the triangle groove at each positive back of scale of secondary chi, secondary chi 0-1cm scale; In secondary chi, the contact pilotage of master calibration chi is flat flat pin to the master calibration chi by the fixing rib indirect securement, directly machine-shaping on the haptic element or by fixed by nut on haptic element, perhaps set up vernier scale, perhaps use displacement sensor and digital display reading device; Fixing rib is worn to hang by flat head screw and is fixed in secondary chi two ends.
The online flat flat pin pin of flat flat pin pin top institute of two haptic element contact pilotages with master calibration chi contact pilotage push up online, three line parallels.
The beneficial effects of the utility model are that simple in structure, easy to operate, measurement result is more accurate, and makes with standard component, can satisfy the batch process needs.

Embodiment
In Fig. 1, two haptic elements 1 are worn about respectively and are hung on the secondary chi 2, and move left and right is also selected identical scale, and are fixed in the triangle groove that the secondary chi back side faces the front scale by nibbed screw 5; Master calibration chi 3 is worn up and down by fixing rib 4 and is hung on the secondary chi 2, and fixing rib 4 is fixed in the two ends of secondary chi 2 by flat head screw 6; Two haptic elements 1 can move left and right on secondary chi 2, and master calibration chi 3 can move up and down on secondary chi 2 and fixing rib 4.
The contact pilotage of two haptic elements is flat flat pin, and contact pilotage slopes inwardly, and contact pilotage is individually fixed on two haptic elements by fastening bolt 7, and two haptic elements are fixed in by nibbed screw in the triangle groove at each positive back of scale of secondary chi, and secondary chi 0-1cm scale is more accurate; In secondary chi, the contact pilotage of master calibration chi also is flat flat pin to the master calibration chi by the fixing rib indirect securement, can be directly machine-shaping on the haptic element or by fixed by nut on haptic element, also can set up vernier scale, perhaps use the direct reading of displacement sensor and digital display device; Fixing rib is worn to hang by flat head screw and is fixed in secondary chi two ends.
The online flat flat pin pin of flat flat pin pin top institute of two haptic element contact pilotages with master calibration chi contact pilotage push up online, three line parallels.
By a master calibration chi and secondary chi is used, the master calibration chi is perpendicular to secondary chi.On secondary chi, move left and right two haptic elements are respectively selected identical scale (x value) and are fixed by nibbed screw.Move up and down the master calibration chi and the reading (a value) of haptic element then.Also can set up more pin-point reading of vernier scale.With reading substitution equation as a result:
Can calculate the result, or with displacement sensor and the direct reading of digital display device.
