Abstract
The utility model relates to a radius measurer capable of measuring radius of any cylinder. A bow-shaped contact and a measuring rod are arranged at the same height, and simultaneously contact an arc surface of a cylinder; the measuring rod is compressed to drive a gear engaged with the measuring rod to rotate and allow a finger on the gear to indicate the radius of the measured cylinder on a dial. After measuring, the measuring rod is rebounded to the original position by a spring, and the finger points to zero scale again. The utility model is capable of measuring radius of a cylinder at any time and in any place without changing position of the measured cylinder, and has the advantages of high accuracy, simple structure, and easy carrying and maintenance.
Description
Affiliated technical field
The utility model relates to a kind of a kind of new equipment of measuring cylindrical radius, and especially energy measurement sector crosssection cylinder or radius are than the instrument of the radius of big column
Background technology
At present, the instrument of known survey cylindrical radius is slide calliper rule, and method is after blocking right cylinder to be measured with slide calliper rule earlier, directly to read diameter from ruler.But, be that fan-shaped right cylinder or the bigger cylindrical radius of radius just can not obtain result accurately for a lot of cross sections
Summary of the invention
In order to overcome prior art in the defective aspect the radius measurement, the utility model provides a kind of instrument, and the radius of the tested cylinder of this device measures especially is suitable for and those sector crosssections or the bigger cylinder of radius
Technical solution adopted in the utility model is: a gear is fixed in the bearing mode in the bottom of support, the tooth of this gear and the sounding rod sounding rod that is meshed is fixed by the pipe and the spring of carriage center, for guaranteeing to measure accurate sounding rod and the arcuate shaped contacts sounding rod driven gear when moving that is located along the same line, by being fixed in the swing of the pointer on the gear, be fixed on the index dial of support, can read below the radius of corresponding testee is the principle of scale mark
R
1: the radius of this instrument internal gear
R: the radius of measured cylinder
L: half of distance between the arcuate shaped contacts
X: the changing value of index dial upper angle
The beneficial effects of the utility model are, can measure anywhere or anytime in the time needn't changing measured circle cylinder position, and the accuracy height, and are simple in structure, are easy to carry about with one and keep in repair
Description of drawings
Following accompanying drawing further specifies the utility model
Fig. 1 is a full sectional view of the present utility model
1. supports, 2. arcuate shaped contacts, 3. sounding rods, 4. springs, 5. gears, 6. pointers, 7. index dials among the figure
Embodiment
In the drawings, the top that makes the top of arcuate shaped contacts (2) and sounding rod (3) is on same straight line, and equate that to the distance of sounding rod (3) axis the central spring (4) of sounding rod (3) in support (1) is enclosed within sounding rod (3) and goes up the end of sounding rod and be meshed with gear (5), pointer (6) is fixed on support (1) and is taken in sounding rod (3) when being compressed, will rotate by driven gear (5), the pointer (6) that is fixed on the gear (5) will indicate a numerical value on index dial, and this numerical value is when to be exactly the radius measurement of measured cylinder finish, and sounding rod (3) can be owing to the acting force of spring (4) is got back to original position.
Claims (4)
1. instrument of measuring cylindrical radius is characterized in that: by sounding rod be fixed in the index dial on the support and have a liking for the gear that closes with it, measure by the pointer that is fixed on the gear.
2. radius measurement device according to claim 1 is characterized in that: direct geared is meshed with sounding rod, and the flexible of sounding rod can rotate by driven gear.
3. radius measurement device according to claim 1 is characterized in that: sounding rod gos deep into the inside of support by the pipe of support.
4. radius measurement device according to claim 1 is characterized in that: sounding rod is by spring, and sounding rod can compression spring, and the spring original position that also sounding rod can be rebounded back makes pointer get back to the zero graduation place simultaneously.
