Description
Technical field
The utility model relates to securing member P value survey instrument technical field, and particularly a kind of countersunk head securing member P value is measured slide calliper rule.
Background technology
As shown in Figure 1, countersunk head securing member P value size refers to that initial measuring position is to the distance of the end face of fastener head from standard, and the initial measuring position of this standard is standard-required dimension D
2virtual intersection with angle [alpha] face.The patent No. is the gauge that 201220236755.8 Chinese patent has been announced a kind of precise engineering surveying securing member P value, this gauge comprises that gauge sleeve, plug-in mounting enter the wimet mold insert in gauge sleeve, in gauge sleeve and wimet edge body, offer the through hole that runs through along the vertical direction setting, this through hole comprises that the aperture on the top that is arranged at wimet mold insert is D
2patchhole section.Above-mentioned gauge in use, inserts the bar portion of measured piece in through hole by the upper surface upside of wimet mold insert, until the conical surface of the head of measured piece contacts with the upper surface of wimet mold insert, then uses ruler or angle square or vernier calliper to measure.When using ruler or angle square, using the upper surface of wimet mold insert as reference side, the known P value of directly measuring, still because the measuring accuracy of ruler and angle square is low, can cause the measuring accuracy of P value low.When using vernier caliper, distance B between distance A between the lower surface of measuring gage sleeve and the upper surface of wimet mold insert, the rule lower surface of sleeve and the end face of the head of measured piece at twice, then calculate P value, P=B-A, because the measurement result of P value need to be obtained indirectly by twice measurement, measurement efficiency is low, has caused the production cycle of securing member long; And the cumulative errors of twice measurement is large, caused that the measuring error of P value is large and measuring accuracy is low.
Summary of the invention
The purpose of this utility model is to provide the countersunk head securing member P value that a kind of measuring accuracy is high to measure slide calliper rule, to solve the low problem of securing member P value measuring accuracy existing in prior art.
To achieve these goals, the utility model adopts following technical scheme: a kind of countersunk head securing member P value is measured slide calliper rule, comprise and extending along left and right directions, the blade with Measurement scales, on blade, be installed with measurement frock, measuring frock is provided with along left and right directions and runs through and measure frock, for the passage of tested countersunk head fasteners shank is installed, the passway of measuring on frock left surface or right flank that is positioned at of passage has the benchmark opening's edge coordinating for the canonical measure reference position block with tested countersunk head fastener head, on blade in being equipped with near a Slideslip of benchmark opening's edge along the left and right directions external pelivimetry pawl that movably slides.
A side relative with slip external pelivimetry pawl of measuring frock has a reference side vertical with the center line of passage, and the benchmark opening's edge of described passage is positioned on the reference side of measuring frock.
Reference side is corresponding with the zero-bit of Measurement scales.
Described measurement frock is provided with for the bar portion for tested countersunk head securing member and along bar portion, radially passes in and out the breach of described passage.
On blade, slidable fit has the vernier caliper electronical display assembly being fixedly connected with slip external pelivimetry pawl.
Measure frock comprise the fixedly matrix that is fixedly arranged on blade with for removable at least two the removable matrixs that are fixedly connected with to measure the countersunk head securing member of different model of fixing matrix, described benchmark opening's edge is arranged on removable matrix.
On blade, be installed with and the external pelivimetry pawl that the slides external pelivimetry pawl that is relatively fixed, fixedly matrix is fixedly arranged on blade by fixing external pelivimetry pawl, fixedly matrix back to the installation locating slot offering in a side of slip external pelivimetry pawl with fixedly external pelivimetry pawl is corresponding.
The beneficial effects of the utility model: in using this process of measuring slide calliper rule, the bar of tested countersunk head securing member is deployed in passage, and the canonical measure reference position that makes the head of tested countersunk head securing member contacts with benchmark opening's edge and by benchmark opening's edge block, follow slip external pelivimetry pawl to the Slideslip near benchmark opening's edge, until during the end contact of the head of slip external pelivimetry pawl and tested countersunk head securing member, the spacing between benchmark opening's edge and slip external pelivimetry pawl is the P value of tested countersunk head securing member.Therefore, adopt the utility model can once directly record the P value of tested securing member, when not reducing measurement efficiency, also improved measuring accuracy, shortened the production cycle of countersunk head securing member, reduced the measuring error of P value.
Further, because reference side is corresponding with the zero-bit of Measurement scales on blade, therefore can directly from blade, read the P value of tested countersunk head securing member, can improve measurement efficiency.
Further, by measuring the breach in frock, the bar portion of tested countersunk head securing member can be along the radially access way of bar portion, compare from the passway access way at benchmark opening's edge place with tested countersunk head securing member, reduce the distance away from measurement frock by slip external pelivimetry pawl, can shorten the running time.
Further, owing to the utlity model has vernier caliper electronical display assembly, when closed slide calliper rule, matrix reference side and slide calliper rule external pelivimetry pawl contacts side surfaces, press the zero clearing position knob on slide calliper rule, can be at any time by Measurement scales zero clearing, because measuring matrix, there is plurality of specifications, variable thickness is fixed identical, has saved the manually time of reading from the Measurement scales of blade, can greatly improve measurement efficiency.
Further, owing to measuring frock, be Split type structure, fixing removable being fixedly connected with between matrix and removable matrix, by replacing removable matrix, and change the benchmark opening's edge size on removable matrix, to adapt to the measurement of the securing member of different model, improve accommodation of the present utility model.
Further, because fixing matrix is fixedly arranged on blade by fixing external pelivimetry pawl, these measurement slide calliper rule can obtain by transforming existing vernier caliper, have simplified production process and difficulty, make this measurement slide calliper rule be convenient to processing and fabricating.
