Abstract
The utility model relates to a continuous measuring mechanism which is arranged at the capacitive-gate digital display caliper or the vernier caliper. The utility model can carry out the continuous on-line measurement along the long direction to the dimension of the definite thickness. The utility model can eliminate the error resulting from different selected points at the time of measurement and the error resulting from different thrust forces of the checking people's hands. The utility model has the advantages of small size, low cost, simple operation and high measuring precision.
Description
Matching product when this utility model relates to capacitance-grid type digital demonstration slide calliper rule or vernier caliper measurement.It is specially adapted to capacitance-grid type digital and shows slide calliper rule (being called for short the digital display chi), with the on-line continuous measurement result, by the data transmission mouth of digital display chi, passes to and carries out data processing in the computing machine.
Present various slide calliper rule all will snap into slide calliper rule on the measurement point of testee when measuring, the numerical value on the Card Reader chi again, but measuring one when having the thickness of object of certain-length, can only be that reconnaissance is measured.This metering system, efficient is low, and because the measurement reconnaissance is different and testing staff's hand push power size all influences measurement result.And this metering system can not be realized continuous on-line measurement.And card base and measured object are two plane contact when measuring, and so also influence measuring accuracy.
Design the purpose of this mechanism, improve detection speed and measuring accuracy on slide calliper rule, realize the continuous on-line measurement of slide calliper rule by an angle sheave is housed.
Figure one sees in the utility model continuous coverage mechanism (I), outer amount card (8) at digital display chi or vernier caliper, (9) on, a measuring seat (1) respectively is housed, (2), have two grooves anyhow on the measuring seat, vertical slot is used for measuring seat is installed in outer amount card, angle sheave (3) is housed in the translot, (4), angle sheave can be gone up at guide wheel shaft (11) and rotate, angle sheave available metal material or nonmetallic materials are processed into also available rolling bearing, on the vernier right side blade of apparent window of digital display footage or vernier caliper, the fixed mount (5) that can arbitrarily fix is arranged, jackscrew above the fixed mount (10) can arbitrarily be fixed fixed mount on blade, bottom is fixed on elastic body (6) on the fixed mount with screw (12).The available spring of elastic body (6) or other resilient material are made.
Measure the example that is applied as of card in addition, when the thickness to an object carries out continuous coverage in the certain-length scope, earlier with two angle sheaves to zero clearing of digital display chi or vernier caliper are write down initial reading together, angle sheave on the measuring seat is blocked measured size on the testee (7), fixed mount (5) is moved to the left and makes elastic body (6) the outer amount card (9) that withstands digital display chi or vernier caliper tightly, elastic body (6) is compressed, fixed mount (5) just can carry out continuous coverage after being fixed on the blade by jackscrew (10).During measurement, angle sheave is continuous rolling on testee, and the contact between angle sheave and the measured object is a line all the time, and the measured size variation by elastic body (6) compensation testee causes the displacement that angle sheave moves.The variation of the measured size in the whole length range is all shown.Realized the certain thickness size, carried out continuous on-line along its length and measure, eliminated the error that produces because of the thrust size of measuring the different sum of errors testing staff hands that produce of reconnaissance simultaneously.If the signal output of digital display chi is linked up with computing machine, measuring-signal is passed in the computing machine handles, will improve detection speed and measuring accuracy greatly.
When not needing continuous on-line measurement, measuring seat (1), (2) can be removed, slide calliper rule can with the same use in the past.
Figure two sees in continuous coverage mechanism (II).
This mechanism measures on card (8), (9) to have a concave station outside, the measuring seat axle (12) that measuring seat is installed in the concave station is fixed on the outer amount card, the hole that measuring seat matches with the measuring seat axle is a slotted hole, have two grooves on the measuring seat, angle sheave (3), (4) are housed in the translot, vertical slot is to be used for measuring seat is fixed on outer amount card, and it can not be rotated.When continuous coverage, with measuring seat (1), (2), half-twist also one pushes away to the right left respectively, and measuring seat promptly is fixed on the outer amount card, and all the other steps are identical with continuous coverage mechanism (I).Can carry out continuous on-line measurement.Not the time spent, with measuring seat (1), (2) push away left to the right respectively, and half-twist, can recover original metering system of digital display chi or vernier caliper.
This utility model continuous coverage mechanism, it is little to have a volume, and cost is low, and is simple to operate, the measuring accuracy advantages of higher.
Figure one is continuous coverage mechanism (I).Figure two is continuous coverage mechanism (II).
