Abstract
A kind of dimension measuring implement, comprises chi frame, fixing gauge head and movable gauge head; Chi frame is] or circular arc, fixing gauge head and movable gauge head are fixedly connected on the inner side at chi frame two ends and upper end level is consistent and fix gauge head between the measurement of partner out yoke and opposite face and comprise pole, fix chaining pin and fixing gage button, fixing gage button is spherical surface, fixing chaining pin is fixedly connected on pole, and fixing gage button is on the top of fixing chaining pin; Movable gauge head comprises bearing, movable chaining pin, movable gage button, dial gauge or front submeter; Movable gage button is on the top of movable chaining pin and be spherical surface; Movable chaining pin and dial gauge constitute lever construction by bearing.Shape due to chaining pin is comparatively thin and the spherical surface of gage button is less, so the external dimensions of boss that can be highly less on measurement plane, and accurate positioning; Have zeroing function again, also can be used for the tolerance relative value measuring fixed measure, reading is simple and reliable, and it is convenient to measure.
Description
Technical field
The present invention relates to a kind of dimension measuring implement, particularly the dimension measuring implement of low height boss on a kind of measurement plane, belongs to Dimensions metrology field.
Background technology
The measurer of conventional measurement size has vernier caliper and milscale, and conventional vernier caliper can be used for measuring length, internal-and external diameter, the degree of depth etc., and precision reaches as high as the hundredths of millimeter, and precision is lower, does not usually adopt when accurately measuring; Conventional milscale, also micrometer caliper is, also can be used to measure length, external diameter etc., precision reaches as high as thousand points of positions of millimeter, precision is higher, but due to milscale gage button and to measure screw sections be the circle having certain diameter length, so when the length of boss highly less on measurement plane or external diameter, because boss height is less, the gage button of milscale and screw rod block the two ends inconvenient operation of boss and easily cause measuring the certain error of generation.
Summary of the invention
The invention provides a kind of dimension measuring implement.Solve the problem highly compared with small boss length high-acruracy survey in plane.
Technical scheme of the present invention is as follows:
A kind of dimension measuring implement, comprises chi frame 1, fixing gauge head 2 and movable gauge head 3; Chi frame is] or circular arc, fixing gauge head 2 and movable gauge head 3 are fixedly connected on the inner side at chi frame 1 two ends and upper end level is consistent and between the measurement of partner out yoke and opposite face; Fixing gauge head 2 comprises pole, fixing chaining pin and fixing gage button, and fixing gage button is spherical surface, and fixing chaining pin is fixedly connected on pole, and fixing gage button is on the top of fixing chaining pin; Movable gauge head comprises bearing 4, movable chaining pin 5, movable gage button 6, dial gauge 7; Movable gage button 6 is on the top of movable chaining pin 5 and be spherical surface; Movable chaining pin 5 and dial gauge 7 constitute lever construction by bearing 4.
On measurement plane during small boss length, first carry out dial gauge zeroing with measurer measurement standard gauge block, and then measure land length, now read dial gauge reading and be the length difference of land length and standard gauge block, can land length be obtained thus.
Further, chi frame has the hole coordinated with movable gauge head bearing, movable gauge head is fixedly connected on chi frame by clamping screw, by unscrewing the relative distance between clamping screw adjustable gauge head and fixing gauge head;
Further, fixing gage button and movable gage button two measuring surface all stud with wimet, make measuring surface energy durable in use;
Further, bearing seat is as the cylindrical and axial direction of seat body and porose in the radial direction and interpenetrate, two supports be parallel to each other with seat body central shaft are had in the both sides of radial hole, pedestal upper end is porose, movable chaining pin center is porose, movable chaining pin is fixedly connected on support and lower end by bearing pin and stretches in the radial hole of bearing seat body, and movable chaining pin center pit and pin are clearance fit; The sleeve of dial gauge inserts in seat body axial hole and forms interference fit with hole, and under dial gauge gauge head and movable chaining pin, end in contact forms lever construction;
Further, according to the scope measured, there is certain pre-pressing amount dial gauge gauge head and movable chaining pin lower end;
Further, chi frame there is lightening hole;
Further, can need to replace dial gauge with clock gauge according to measuring accuracy.
Effect of the present invention and benefit are:
Shape due to chaining pin is comparatively thin and the spherical surface of gage button is less, so the external dimensions of boss that can be highly less on measurement plane, and accurate positioning, measuring accuracy is high; Again owing to there being zeroing function, so also can be used for the tolerance relative value measuring fixed measure, reading is simple and reliable, and it is convenient to measure, and raises the efficiency.
