Abstract
The invention discloses a pitch vernier caliper. The pitch vernier caliper comprises a caliper body (1) and a vernier (2), wherein the vernier (2) is mounted on the caliper body (1) and can slide along the caliper body (1); scales are formed on the caliper body (1); a fastening screw (3) is mounted at the upper part of the vernier (2); the lower part of the vernier (2) is fixedly connected with a measuring jaw A (4); scales corresponding to the scales on the caliper body (1) are formed on the vernier (2). The pitch vernier caliper is characterized in that the lower left side of the caliper body (1) is fixedly connected with a measuring jaw B (8); a blind hole (9) is formed in the lower part of the measuring jaw B (8); a threaded hole (7) is formed in the left side of the measuring jaw B (8); the blind hole (9) is communicated with the threaded hole (7); a measuring needle (5) is mounted in the blind hole (9) in a matched manner; a screw (6) is mounted in the threaded hole (7). The pitch vernier caliper is simple in structure, convenient, feasible, and accurate in measurement.
Description
Technical field
The invention belongs to pitch-row survey instrument technical field, relate in particular to a kind of pitch-row vernier caliper.
background technology
In securing member process, much linear dimension is all adopt general measurer to measure, and the measurer usually adopted has common calliper, milscale, dial gauge.But in actual production, the portion size of some product cannot obtain with general gage measuring, needs design specialized measurer.
In prior art, for the band insurance hexagon head bolt (nail) in hole or hexagonal nut, two general vernier calipers of size cannot be measured below: (1) insures the size of center, hole to bolt (nail) or nut hexagonal prismoid; (2) center, hole is insured to bolt (nail) head end or the size to hexagonal nut end face.As such size will be obtained, need repeatedly to add and subtract calculating, not only have impact on measuring accuracy, and trivial operations.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and a kind of structure of providing simple, facilitate feasible, measure accurate pitch-row vernier caliper.
The object of the invention and solve its technical problem underlying and realize by the following technical solutions:
A kind of pitch-row vernier caliper of the present invention, comprise blade, vernier, vernier to be arranged on blade and can to slide along blade, blade is provided with scale, trip bolt is equipped with on vernier top, vernier bottom is fixedly connected with measuring jaw A, vernier is provided with the scale corresponding with the scale on blade, wherein: the lower left side of blade is fixedly connected with measuring jaw B, measuring jaw B bottom is provided with blind hole, and be provided with threaded hole on the left of measuring jaw B, blind hole is connected with threaded hole, coordinate in blind hole and metering pin is housed, threaded hole is built with screw.
Above-mentioned pitch-row vernier caliper, wherein: described blind hole and threaded hole vertical arrangement.
Above-mentioned pitch-row vernier caliper, wherein: when described measuring jaw A and metering pin are fitted, zero groove on vernier overlaps with zero groove on blade.
The present invention compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, pitch-row vernier caliper of the present invention, the lower left side of described blade is fixedly connected with measuring jaw B, measuring jaw B bottom is provided with blind hole, threaded hole is provided with on the left of measuring jaw B, be convenient to by threaded hole built with screw to blind hole built with metering pin carry out screens, thus realize metering pin to insert hexagon head bolt (nail) or hexagonal nut insurance hole in position measurement; When described measuring jaw A and metering pin are fitted, zero groove on vernier overlaps with zero groove on blade, is conducive to the measurement of pitch-row size; Vernier is provided with the scale corresponding with the scale on blade, ensure that the accuracy of measurement.In a word, structure of the present invention is simple, it is feasible to facilitate, measure accurately, is applicable to promoting the use of of pitch-row dimensional measurement.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the pitch-row vernier caliper embodiment proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
See Fig. 1 to Fig. 3, pitch-row vernier caliper of the present invention, comprise blade 1, vernier 2, vernier 2 to be arranged on blade 1 and can to slide along blade 1, blade 1 is provided with scale, trip bolt 3 is equipped with on vernier 2 top, vernier 2 bottom is fixedly connected with measuring jaw A4, vernier 2 is provided with the scale corresponding with the scale on blade 1, and wherein: the lower left side of blade 1 is fixedly connected with measuring jaw B8, measuring jaw B8 bottom is provided with blind hole 9, threaded hole 7 is provided with on the left of measuring jaw B8, blind hole 9 is connected with threaded hole 7, and coordinate in blind hole 9 and metering pin 5 is housed, threaded hole 7 is built with screw 6.Described blind hole 9 and threaded hole 7 vertical arrangement.When described measuring jaw A4 and metering pin 5 are fitted, zero groove on vernier 2 overlaps with zero groove on blade 1.
During use, see Fig. 4 to Fig. 5, first choose suitable metering pin 5, ensure that metering pin 5 can pass through the insurance hole 11 of hexagonal nut 10 smoothly, but gap can not be excessive, keeps gap to be that 0.02mm ~ 0.05mm is advisable.Moving cursor 2 makes measuring jaw A4 and metering pin 5 fit, and adjustment screw 6 makes zero groove on vernier 2 overlap with zero groove on blade 1.
(1) the size L of center, insurance hole 11 to hexagonal nut 10 hexagonal prismoid of hexagonal nut 10 is measured.Directly inserted by metering pin 5 in insurance hole 11, the hexagonal prismoid of mobile measuring jaw A4 and hexagonal nut 10 is fitted, and now the reading value of vernier caliper is size M, and required size L is the radius d/2 that size M adds hole 11 of insuring, i.e. L=M+d/2.
(2) the size C of center, insurance hole 11 to hexagonal nut 10 end face of hexagonal nut 10 is measured.Directly inserted by metering pin 5 in insurance hole 11, the end face of mobile measuring jaw A4 and hexagonal nut 10 is fitted, and now the reading value of vernier caliper is required size C.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
