The utility model to achieve the above object, is achieved through the following technical solutions, a kind of two pitchs of holes or hole and sideline The measuring device of spacing, it is characterized in that: including guide sleeve, conehead, adjusting screw and compressed spring, the guide sleeve is led by circular cone The L-shaped whole guide sleeve ontology of longitudinal section shape is constituted to square and measuring block, circular cone guiding square center is equipped with The upper end of stepped hole, stepped hole is equipped with internal screw thread, and internal screw thread is spirally connected with adjusting screw, falls in the lower stomidium of stepped hole equipped with circular cone Angle is sliding combined with conehead in stepped hole, and the circular cone of conehead is matched with the circular cone chamfering of stepped hole, the adjusting screw and conehead Between be equipped with compressed spring.
The two sides of measuring block are parallel to each other in the entirety guide sleeve ontology, and are set as interior measurement plane and external pelivimetry is put down Face, interior measurement plane and external pelivimetry plane respectively with circular cone guiding the ladder axially bored line of square it is parallel, and with whole guide sleeve sheet The baseplane of body is vertical.
The ladder axially bored line of circular cone guiding square is flat to interior measurement plane and external pelivimetry in the entirety guide sleeve ontology The distance in face is set as integer definite value.
The utility model has the advantages that compared with prior art, the utility model structure is simple, easily manufactured, accurate positioning is reliable, volume Small and exquisite easy to carry, measurement method can flexibly cooperate existing measuring tool to use, and the pitch-row of 0.1mm is no more than suitable for precision Measurement.It especially can quickly, accurately and reliably measure sheet metal component mesoporous and other holes or the distance between hole and sideline.

Specific embodiment
In conjunction with the preferred embodiment, to according to specific embodiment provided by the utility model, details are as follows:
It is detailed in attached drawing 1, present embodiment discloses a kind of two pitchs of holes or the measuring devices in hole and sideline spacing, including guiding Set 1, conehead 2, adjusting screw 3 and compressed spring 4, the guide sleeve constitute longitudinal direction by circular cone guiding square 1-1 and measuring block 1-2 The L-shaped whole guide sleeve ontology of cross sectional shape, circular cone guiding square center are equipped with stepped hole 1-1-1, stepped hole it is upper End is equipped with internal screw thread 1-1-2, and internal screw thread is spirally connected with adjusting screw, and circular cone chamfering 1-1-3, ladder are equipped in the lower stomidium of stepped hole Conehead is sliding combined in hole, the circular cone of conehead is matched with the circular cone chamfering of stepped hole, set between the adjusting screw and conehead There is compressed spring.The two sides of measuring block are parallel to each other in the entirety guide sleeve ontology, and be set as interior measurement plane 1-2-1 with External pelivimetry plane 1-2-2, interior measurement plane and external pelivimetry plane are parallel with the circular cone guiding ladder axially bored line of square respectively, and with The baseplane 5 of whole guide sleeve ontology is vertical.The geometric accuracy and geometric tolerance at whole each position of guide sleeve ontology can guarantee Measurement accuracy.It can also be different according to its different geometric tolerance precision of measurement accuracy, therefore can guarantee to reduce processing cost.
The ladder axially bored line of circular cone guiding square is to interior measurement plan range a and ladder in the entirety guide sleeve ontology The distance b of axially bored line to external pelivimetry plane is set as integer definite value.Be set as integer definite value can be convenient measurement after calculate.According to Multiple specifications can be set in difference measurement distance length, and the numerical value of a or b are identified on whole guide sleeve ontology.
Guide sleeve and conehead use A3 material, are heat-treated after processing, to guarantee its abrasion hardness.
Measurement process
Embodiment 1
It is detailed in attached drawing 2 or 3, for measuring two distance between borehole.
The device conehead is put into the hole to be measured when use, plane where the baseplane and hole of whole guide sleeve ontology Contact, since interior measurement plane is parallel with the circular cone guiding ladder axially bored line of square, and the baseplane with whole guide sleeve ontology Vertically, to guarantee conehead axis perpendicular to measured hole, internal compression spring makes conehead resist hole edge, is held in position, and adjusts spiral shell Silk is to adjustment spring elastic force;Slide calliper rule or tape measure are passed through into the outer of the interior measurement plane of the first hole guide sleeve and the second hole guide sleeve The distance for measuring plane is c, c-b=c1c1Between the interior measurement plane and the second hole ladder axially bored line of the first hole guide sleeve away from From;c1+ a is two distance between borehole, distance between as Kong Yukong.
It can be measured by the scribing line of whole guide sleeve bodies top and another sideline to be measured using steel ruler;
When measuring two distance between borehole, then the device using two pieces is needed to measure, method is similar with single hole measurement.
It (1) being capable of the distance between rapid survey sheet metal component mesoporous and other holes or sideline.
(2) easy to operate when using, control force direction is not needed, guarantees that conical head, and only need to be with perpendicular to institute's gaging hole Plane where measured hole and guide sleeve bottom plane compress, so that reliability when improving measurement, reduces operation difficulty.
(3) in the prior art, the aperture in measured hole is smaller relative to conical head, and shaking when measurement is more obvious, and this Device is where guide sleeve bottom surface and hole when plane contact, and Kong Yue little, conical head amount of recovery is bigger, and the decrement of spring is bigger, Pressing force between conical head and hole edge is also bigger, so that positioning is more accurate, it is not in cause to survey because hole is too small The inaccurate situation of amount occurs.
(4) measurement is accurate, and conical head is not easy to tilt relative to hole, and the dimensional accuracy obtained is high, can satisfy actual production Demand.
(5) device volume is small and exquisite, can cooperate with a variety of measurers and measure.
Above-mentioned reference embodiment is to say to the detailed description of the measuring device in two pitch of holes of one kind or hole and sideline spacing Bright property without being restrictive, several embodiments can be enumerated according to limited range, therefore practical new not departing from this Change and modification under type general plotting should belong within the protection scope of the utility model.
