Description

Pitch-row vernier caliper
Technical field
The utility model belongs to pitch-row survey instrument technical field, relates 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
A kind of structure that the purpose of this utility model is to overcome above-mentioned shortcoming and provides is simple, it is feasible to facilitate, measure accurate pitch-row vernier caliper.
The utility model object and solve its technical problem underlying and realize by the following technical solutions:
A kind of pitch-row vernier caliper of the present utility model, 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 utility model compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, pitch-row vernier caliper of the present utility model, 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, the utility model structure is simple, it is feasible to facilitate, measure accurately, is applicable to promoting the use of of pitch-row dimensional measurement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of measuring jaw A;
Fig. 3 is the structural representation of measuring jaw B;
Fig. 4 is the first using state figure of the present utility model;
Fig. 5 is the second using state figure of the present utility model.
Identify in figure:
1, blade; 2, vernier; 3, trip bolt; 4, measuring jaw A; 5, metering pin; 6, screw; 7 threaded holes; 8, measuring jaw B; 9, blind hole; 10, hexagonal nut; 11, hole is insured.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to pitch-row vernier caliper embodiment, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
See Fig. 1 to Fig. 3, pitch-row vernier caliper of the present utility model, 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, 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, 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 utility model, not any pro forma restriction is done to the utility model, anyly do not depart from technical solutions of the utility model content, the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
