Abstract
A vernier caliper comprises a main ruler, a vernier, a depth ruler, outer measuring claws and inner measuring claws; the outer measuring claws and the inner measuring claws are fixed on the main ruler through a fastening screw; and free ends of the inner measuring claws are provided with extending parts. The vernier caliper of the utility model which is formed through the transformation of an original device is advantageous in simple structure, convenient operation and easiness in implementation. Based on an expanded usage rang, the final measurement accuracy of the vernier caliper is not affected.
Description
Technical field
The utility model relates to a kind of measurement instrument, specifically a kind of vernier caliper.
Background technology
Vernier caliper is one of measurer the most frequently used in the machinery manufacturing industry, it is to utilize the poor and accumulating value of ruling span on blade main scale and the vernier to come subdivision and count, its simple structure, easy to use, measurement range is large, and purposes is wide, inside and outside size that can measuring workpieces, such as length, width, internal diameter and external diameter, pitch-row, the degree of depth and height etc.If run into when need measuring stepped hole or the degree of depth than the internal diameter of deep hole, conventional vernier caliper can't be satisfied the demand but in use.
The utility model content
Can't measure the problem of internal diameter at special occasions for vernier caliper in the solution prior art, the utility model provides a kind of vernier caliper, forms through transforming on the basis of conventional vernier caliper, and is simple in structure, easy to operate.
The utility model is to address the above problem the technical scheme that adopts to be: a kind of vernier caliper, comprise main scale, vernier, pit gauge, external pelivimetry pawl and interior measuring claw, external pelivimetry pawl and interior measuring claw are fixed on the main scale by holding screw, and the free end of described interior measuring claw is equipped with extension component.
Described extension component is fixedly connected on the free end of interior measuring claw.
Described extension component and free-ended being connected to of interior measuring claw removably connect.
The measuring principle that extension component of the present utility model is based on vernier caliper arranges, and in use, will consider the error that causes because setting up extension component when calculating final reading.
Beneficial effect: the utility model forms the basis transformation of original device, and is simple in structure, easy to operate, is easy to realize, on the basis that has enlarged usable range, do not affect final measuring accuracy.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1, external pelivimetry pawl, 2, interior measuring claw, 2-1, extension component, 3, holding screw, 4, vernier, 5, main scale, 6, pit gauge.
Embodiment
As shown in Figure 1, a kind of vernier caliper, comprise main scale 5, vernier 4, pit gauge 6, external pelivimetry pawl 1 and interior measuring claw 2, external pelivimetry pawl 1 and interior measuring claw 2 are fixed on the main scale 5 by holding screw 3, the free end of described interior measuring claw 2 is equipped with extension component 2-1, extension component 2-1 can by be fixedly connected with the free end that is located at interior measuring claw 2 such as the mode of welding, also can connect, be located at interior measuring claw 2 free-ended two ends by Hose Jacket such as riveted joint, bolt by removably connecting.
In use, with soft cloth measuring claw is wiped clean, it is closed up, whether the zero groove of checking vernier 4 and main scale 5 aligns, if alignment can directly be measured, then will not keep zero error in mind if there is alignment: the zero graduation line of vernier is in the positive zero error that is on blade zero graduation line right side, and in blade zero graduation line left side is the negative zero error; During measurement, the right hand is arrested main scale 5 blades, thumb moving cursor 4, left hand is taken the object of external diameter to be measured, makes determinand between external pelivimetry pawl 1, when measuring internal diameter, interior measuring claw 2 is stretched in the object of internal diameter to be measured, when detected part and measuring jaw tightly are affixed, i.e. readable, the measuring principle of vernier caliper arranges owing to extension component of the present utility model is based on, and will consider the error that causes because setting up extension component when calculating final reading.In order to obtain correct measurement result, can repeatedly measure, namely the different directions on the same cross section of part is measured.
Claims (3)
