Abstract
The utility model relates to a vernier external micrometer, which is composed of a main ruler, a walk arm, a fixed sleeve, a micrometric screw, a microdrum and a force-measuring constant device. The vernier external micrometer is characterized in that the walk arm is sheathed on the main ruler and provided with a walk arm stopper and a post rod, the other end head of the main ruler is fixedly connected with the fixed sleeve that is provided with a micrometric screw stopper, the micrometric screw which is installed in the fixed sleeve is fixedly connected to the microdrum, and the end head of the micrometric screw is provided with the force-measuring constant device. The utility model has the advantages of convenient operation, fast measurement, no regulative operation, dual function of a vernier caliper and an outside micrometer, large measuring range and high measuring precision.
Description
The utility model relates to a kind of vernier outside micrometer, relates to a kind of have vernier caliper and outside micrometer dual-use function specifically, and measurement range is big, the workpiece article outside diameter measuring instrument that measuring accuracy is high.
At present, in the measurement of workpiece article external diameter, measure for big workpiece vernier caliper commonly used, but because its structural reason, precision is not enough during measurement; For small workpiece outside micrometer commonly used, yet in order to have guaranteed certain precision, adopt many ruler measurement usually: general outside micrometer commonly used has 0-25mm, 25-50mm, presses the 25mm segmentation, needs 12 rulers up to 300mm; 300-400mm, 400-500mm press the 100mm segmentation, and up to 1000mm etc., the serial chi of maximum measurement range 3000mm has many.Use chi according to the size of measured object is selected in use, illustrate, divided for three steps as the workpiece external diameter of surveying 98.15mm: 1, select chi, choose the outside micrometer of 75-100mm according to workpiece size; 2, adjustment is transferred the error of testing chi according to the GB1216-75 standard with the par of 75mm, makes it correctly to zero; 3, measure, rotation microdrum 48 encloses 99mm place, turns round to make the chi end just across the tested place of workpiece reading numerical values again.That is to say existing each survey instrument, its measurement range is little, need have manyly survey instrument during to workpiece article outside diameter measuring, and this has brought great inconvenience for manufacturing, keeping, the use of instrument, has also strengthened the manufacturing cost of instrument.The structure of existing in a word vernier caliper and outside micrometer awaits further improvement.
The purpose of this utility model just is to design a kind of have vernier caliper and outside micrometer dual-use function, and measurement range is big, and the vernier outside micrometer that measuring accuracy is high to be to remedy the deficiency of existing vernier caliper and outside micrometer.
The purpose of this utility model is achieved in that it is mainly by main scale (1), trip arm (2), fixed muffle (4), micrometric screw (5), microdrum (6), the constant device of dynamometry (7) is formed, it is characterized in that being carved with on the main scale (1) main scale scale (3), main scale (1) upper sleeve through has trip arm (2), trip arm (2) is provided with trip arm stopper (8) and push rod (12), another termination of main scale (1) is connected with fixed muffle (4), fixed muffle (4) is provided with micrometric screw detent (9) and fixed muffle scale (11), be provided with micrometric screw (5) in the fixed muffle (4), be connected with microdrum (6) on the micrometric screw (5), the termination of micrometric screw (5) is provided with the constant device of dynamometry (7), and microdrum (6) is provided with microdrum scale (10).
The utility model compared with prior art, it is easy to use, measures fast, non-regulating has the dual-use function of vernier caliper and outside micrometer, measurement range is big, the measuring accuracy height has remedied the deficiency of existing vernier caliper and outside micrometer.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is the utility model one-piece construction synoptic diagram.
Among the figure: 1, main scale, 2, the trip arm, 3, the main scale scale, 4, fixed muffle, 5, micrometric screw, 6, microdrum, 7, the constant device of dynamometry, 8, the trip arm stopper, 9, the micrometric screw detent, 10, the microdrum scale, 11, the fixed muffle scale, 12, push rod.
Referring to accompanying drawing, as we know from the figure the utility model it have the dual-use function of vernier caliper and outside micrometer, mainly by main scale 1, trip arm 2, fixed muffle 4, micrometric screw 5, microdrum 6, the constant device 7 of dynamometry is formed, be carved with main scale scale 3 on the main scale 1 and be coated with trip arm 2, trip arm 2 is provided with trip stern detent 8 and push rod 12, the end face of push rod 12 is equivalent to a card face of vernier caliper and outside micrometer, another termination of main scale 1 is connected with fixed muffle 4, fixed muffle 4 is provided with micrometric screw detent 9 and fixed muffle scale 11, be provided with micrometric screw 5 in the fixed muffle 4, be connected with microdrum 6 on the micrometric screw 5, the termination of micrometric screw 5 is provided with the constant device 7 of dynamometry, microdrum 6 is provided with microdrum scale 10, and the end face of micrometric screw 5 is equivalent to another card face of vernier caliper and outside micrometer; The composition of fixed muffle 4, micrometric screw 5, microdrum 6 and the constant device 7 of dynamometry, its principle and outside micrometer are close, and those skilled in the art all can understand, and repeat no more here.
During use, as: the workpiece of measuring 98.15mm equally, as long as move trip arm 2 to the 99mm place, screw trip arm stopper 8 location, rotate microdrum 6 again, make the chi end span in the tested place of workpiece, even the end face of the end face of push rod 12 and micrometric screw 5 is across the tested place of workpiece, screw micrometric screw detent 9 location, its workpiece size is: the reading on the main scale 1 subtracts 1, adds the value that shows on the microdrum 6 again.
That is: workpiece size=99mm-1mm+0.15mm=98.15mm.
