Abstract
The utility model relates to a doable head internal measuring micrometer, which is characterized in that the two group of measuring surfaces initialized with different original measuring values, thereby enlarging measuring range on the basis of using one group of micrometer screw pair. The utility model has the advantages of simple structure and easy installation and use.
Description
Technical field
The utility model relates to a kind of milscale that is used for survey in the double end.
Technical background
Existing internal measuring micrometer has only one group to measure face, so after the initial measured value customization of the stroke of milscale micrometric screw and the face of measurement, its measurement stroke is subjected to the restriction of the stroke of micrometric screw, and a kind of measurement range can only be arranged.
Summary of the invention
The purpose of this utility model is the deficiency that has overcome existing internal measuring micrometer, designed a kind of have simple in structure, be easy to assembling, cost is not high, economical and practical, and can under the condition that does not change the micrometric screw stroke, make an internal measuring micrometer have the technical scheme of two kinds of continuable measurement ranges.
Technical scheme is that this double end internal measuring micrometer has two groups to measure face.One group of measurement face is 9, and another group measurement face is 10, and therefore, this milscale can have two kinds of measurement ranges.In addition, but realized the continuity of two kinds of measurement ranges by the control of measuring the relative size of faces to two groups.Therefore, it is economical and practical self-evident.
Description of drawings
Fig. 1 is that adjusting pin is installed in the example structure synoptic diagram on the fixing measuring jaw;
Fig. 2 is that adjusting pin is installed in the example structure synoptic diagram on the movable measuring jaw;
Fig. 3 is the Facad structure synoptic diagram of measurement face 9 and reading;
Fig. 4 is the Facad structure synoptic diagram of measurement face 10 and reading.
Wherein: 1. tapped through hole, 2. movable measuring jaw, 3. step axle, 4. guide pipe, 5. fixing measuring jaw, 6. threaded sleeve, 7. orienting sleeve, 9,10. measurement face.
Embodiment
Fig. 1 is an organization plan one of the present utility model: fixedly measuring jaw 5, guide pipe 4 adopt with threaded sleeve 6 and fixedly connected.Orienting sleeve 7 adopts with movable measuring jaw 2 fixedlys connected, and moving linearly in the gathering sill of guide pipe 4 together.Adjusting mechanism: can be screwed into the gathering sill tolerance clearance that the M3 jackscrew is regulated movable measuring jaw 2 and guide pipe 4 in two M3 of the place tapped through holes 1 on the movable measuring jaw 2, thus the swing of control activity measuring jaw 2; Fixedly measuring jaw 5 and movable measuring jaw 2 on it measurement face 9 and 10 liang of groups of measurement face measurement face can set the initial measured value of different measurements, thereby enlarge measurement range using on one group of basis of measuring screw pair.Fixedly can be pressed into taper pin in two Φ of place, 1.5 through holes 8 on the measuring jaw 5 and regulate the movable measuring jaw 2 and the fixing absolute dimensions of the measurement face 9 of measuring jaw 5 correspondences and 10 liang of groups of measurement face measurement face initial value by the distortion of measuring jaw.This adjusting mechanism equally also can be realized on movable measuring jaw 2 in the installation by taper pin.
The revolute that this case uses a pair to be made up of the step axle 3 and the orienting sleeve 7 of micrometric screw front end is finished the transmission to movable measuring jaw 2.When micrometric screw rotates when mobile forward or backward, because the gathering sill of guide pipe 4 makes the revolute drive activity measuring jaw 2 do dead-beat feedings of being made up of the step axle 3 and the orienting sleeve 7 of micrometric screw front end forward or backward to the effect of movable measuring jaw 2, thereby realized the measurement of this internal measuring micrometer.
Fig. 2 is an organization plan two of the present utility model: fixedly measuring jaw 5, guide pipe 4 adopt with threaded sleeve 6 and fixedly connected.Orienting sleeve 7 adopts with movable measuring jaw 2 fixedlys connected, and moving linearly in the gathering sill of guide pipe 4 together.Adjusting mechanism: can be screwed into the gathering sill tolerance clearance that the M3 jackscrew is regulated movable measuring jaw 2 targeting parts and guide pipe 4 in two M3 of the place tapped through holes 1 on the movable measuring jaw 2; Fixedly measuring jaw 5 and movable measuring jaw 2 on it measurement face 9 and 10 liang of groups of measurement face measurement face can set the initial measured value of different measurements, thereby enlarge measurement range using on one group of basis of measuring screw pair.The M2 jackscrew be can be screwed in two M2 of the place tapped through holes 8 on the movable measuring jaw 2 and movable measuring jaw 2 and fixing two groups of relative sizes of measuring faces of measuring jaw 5 correspondences regulated.
The revolute that this case uses a pair to be made up of the step axle 3 and the orienting sleeve 7 of micrometric screw front end is finished the transmission to movable measuring jaw 2.When micrometric screw rotates when mobile forward or backward, because the gathering sill of guide pipe 4 makes the revolute drive activity measuring jaw 2 do dead-beat feedings of being made up of the step axle 3 and the orienting sleeve 7 of micrometric screw front end forward or backward to the effect of movable measuring jaw 2, thereby realized the measurement of this internal measuring micrometer.
Two kinds of structures of the present utility model are all simpler, and the processing of part is not had very high specific (special) requirements, assemble also comparatively simply, are fit to fully produce in batches.
Fig. 3, Fig. 4, for the utility model scheme is applied in two kinds of measurement states on surveying in the double end, two groups of grooves are adopted in this case, are convenient for measuring, reading.
Fig. 3 is the measurement state of this case 5-30mm measurement range; Fig. 4 is the measurement state of 30-55mm measurement range.
Claims (1)
1. a double end internal measuring micrometer is characterized in that it is provided with two groups and measures face, measures face (9) for one group, and another organizes measurement face (10), and its two groups of measurement faces are set different initial measured values for.
