Abstract
The utility model discloses a micrometer which measures an inner diameter. Comprising a centering measure base, a test meter, an extension rod, a commutative measuring head and a handle, etc., and the utility model can carry out directly measuring a straight hole, a cavity hole and a hole groove, etc. The utility model has the advantages of high precision, simple structure, small size, convenient operation and portability and low cost.
Description
The utility model belongs to the length testing technical field.
The existing inside meter of measuring internal diameter, a kind of is the lever driven type, a kind of is linear driven type, and all is that lever turns to 90 ° to carry out letter and connect measurement greater than the inside meter of the above measurement range of 50-160mm, because its measurement transmission chain length, complex structure, moving part is easy to wear, causes the indicated value instability of measurer own, and measurement function only limits to straight hole, to lumen pore, hole groove etc. are energy measurement not.
The purpose of this utility model is to provide a kind of abbe ' s principle that meets the length measurement technique cardinal rule, and the shortest chain tape principle and simple in structure is cheap, the measuring accuracy measurement instrument accurately and reliably that makes easy to use.
The utility model is realized by following measures, on the survey seat＜1〉that centers, adorn test chart＜2 〉, go up at the helmet screwed pipe (central siphon) (7) of the other end of test chart＜2〉and extension bar (4) to be installed to be connected and fixed interchangeable gauge head (6), gauge rod gauge head (15) forms one with interchangeable gauge head (6) and directly measures axis; Bridge (14) design of protecting of surveying seat (1) that centers has two supports symmetrical with gauge rod gauge head (15), and the measurement axis that guarantees gauge rod gauge head (15) and interchangeable gauge head (6) is at the bosom in aperture diameter.
The utility model is compared with existing inside meter, and its advantage is: employing can directly be measured axis, has avoided lever to turn to 90 ° letter to meet the indicated value instability that measurement produces, it has simplified the measurement driving-chain, easy to manufacture, with low cost, measurement function expands to lumen pore and hole groove; Its volume is little, portably uses conveniently.
The utility model will be further described below in conjunction with accompanying drawing;
(1) centers and survey seat, (2) test chart, (3) pointer, (4) extension bar, (5) double-screw bolt platform, (6) interchangeable gauge head, (7) helmet screwed pipe (central siphon), (8) scale, (9) axle sleeve, (10) spiral shell hoop, (11) screwed pipe, (12) inner sleeve, (13) stage clip, (14) and protect bridge, (15) gauge rod gauge head, (16) double-screw bolt boss, (17) handle.
Accompanying drawing is scale construction synoptic diagram in the portable multifunctional of measuring internal diameter
Interior scale centers and surveys the axle sleeve (9) of test chart (2) of packing in the screwed pipe (11) of (1) inner sleeve (12) one ends, and gauge rod gauge head (15) stretches out inner sleeve (12) upper surface, and keeps symmetrical and protect bridge (14) two supports; The fastening axle sleeve of spiral shell hoop (10) lock ring screwed pipe (11) (9), inner sleeve (12) are gone up pillow block dress stage clip (13), protect bridge and slide up and down at inner sleeve, and double-screw bolt boss (15) is to its guiding; Handle (17) also can be installed on the double-screw bolt boss.Go up installation extension bar (4) to be connected and fixed interchangeable gauge head (6) at the helmet screwed pipe (central siphon) (7) of test chart (2) other end, go up at double-screw bolt platform (5) in case of necessity handle (17) is installed, center and survey seat (1), extension bar (4) and interchangeable gauge head (6) all can change its correspondingly-sized like the different series specification of interior scale, to reach the work efficiency that supporting assembling is measured.Press the measured workpiece icon size with outside micrometer and proofread and correct interior scale, put into the hole then, the travel compression of gauge rod gauge head (15); Set upright handle (17),, observe the poor of the minimum scale value of pointer (3) turn-over point and scale zero-bit, be tested aperture error along axially bored line trace swing back and forth.
Claims (4)
1, a kind of interior scale of portable multifunctional of surveying the measurement internal diameter that seat (1), a test chart (2), the interchangeable gauge head of extension bar (4) (6) and handle (17) form by centering, it is characterized in that centering surveying on the seat (1) and adorn a test chart (2), on the helmet screwed pipe (central siphon) (7) of test chart (2) other end, adorn an extension bar (4), to be connected and fixed interchangeable gauge head (6), to form and directly measure axis.
2, according to the described interior scale of claim 1., bridge (14) design of protecting of surveying seat (1) that it is characterized in that centering is formed in two symmetrical supports of gauge rod gauge head (15).
3, according to the described interior scale of claim 1., it is characterized in that centering surveying in the seat (1) and be provided with inner sleeve (12), inner sleeve (12) one ends are provided with screwed pipe (11) again, a spiral shell hoop (10) are arranged in order to fastening test chart (2) Upper shaft sleeve (9) on (11); Inner sleeve (12) upper end makes pillow block shape, and stage clip (13) is housed on the pillow block, and the face of cylinder at inner sleeve (12) middle part is provided with double-screw bolt boss (16), makes it to slide up and down in order to the guiding bridge of surveying on the seat (14) that protects that centers; Handle (17) is housed on the double-screw bolt boss.
4, according to claim 1. described in scale, it is characterized in that centering and survey seat (1), extension bar (4) and interchangeable gauge head (6) all can be like the different series specification of interior scale its correspondingly-sized of conversion, to reach the effect of supporting assembling measurement.
