Abstract
The invention relates to a special clamp for measuring the measurement force of a pore size micrometer, comprising a chassis, measuring arms, measuring arm bolts, fastening frames, fastened screws and digital display push-pull dynamometers, wherein the chassis is made into a disc, a through hole for installing the pore size micrometer is arranged in the center of the disc; three pits for installing the measuring arms are evenly distributed at the edge of one face of the disc, and a screw hole is arranged in each pit; the cross section of each measuring arm is made into an I-shaped form; an I-shaped hole which is matched with the cross section of each measuring arm is arranged near one end of the cross section of each fastening frame, a through hole which is matched with each digital display push-pull dynamometer is arranged near the other end of the cross section of each fastening frame, a screw hole which is matched with each fastening bolt is arranged on the end surface of the fastening frame at one side of the through hole, and the screw holes are communicated with the through holes; the three measuring arms are arranged in the pits of the chassis and fastened by the measuring arm bolts; the three fastening frames are respectively arranged on the three measuring arms in a sliding fit way; and the three digital display push-pull dynamometers are respectively arranged on the three fastening frames and fixed by the fastening bolts. The invention has the advantage of satisfying the measuring force detection requirement of the pore size micrometer.
Description
Technical field: the invention is the auxiliary clamp that is used for detection aperture miking power.
Background technology: the aperture milscale is to utilize the rotation of screw thread cone to promote the measurement instrument that three measuring claws carry out inside diameter measurement.When measuring the aperture, select the aperture milscale that is complementary with tested aperture, three measuring claws of aperture milscale are put in the measured hole; Device for measuring force on the milscale of rotation aperture makes ergometry under effect between 10～35N, impels the microdrum of aperture milscale to move forward; Promoting three measuring claws stretches out three measuring claws is fully contacted with the measured hole inside surface; When device for measuring force sends three soundings sound, represent that added ergometry meets the dynamometry value requirement of measurer, reads calibration value by microdrum; The size of aperture miking power value is mainly determined by the device for measuring force inner spring; The big or small of ergometry directly influences aperture miking precision, and the aperture milscale needs regularly to detect, but the aperture miking appearance of present no standard.
Summary of the invention: the purpose of the invention provides a kind of detection aperture miking force measurement aperture miking power unit clamp; The purpose of the invention is to realize through following technical scheme: measure aperture miking power unit clamp; It is characterized in that constituting by chassis, three test arms, three test arm bolts, three fastening frames, three trip bolts and three digital display push-and-pull dynamometers; Disk is processed on the chassis, makes the through hole that the aperture milscale is installed at the disc centre place, and the edge on the disk one side makes three recesses that test arm is installed of even distribution; In recess, make a threaded hole respectively; The test arm xsect is processed I shape, and the fastening frame xsect is processed the I shape hole that cooperates with the test arm xsect near an end place, and the fastening frame xsect is processed the through hole that cooperates with digital display push-and-pull dynamometer near other end place; On the fastening frame end face of through hole one side, make the threaded hole that cooperates with trip bolt; Threaded hole communicates with through hole, three test arms is contained in respectively in the recess on chassis and uses the test arm bolted, and three fastening frames are contained in respectively on three test arms; Be slidingly matched, three digital display push-and-pull dynamometers be contained in respectively on three fastening frames fix with trip bolt.
The advantage of the invention: satisfied the detection requirement of aperture miking power.

Fig. 2 is an A-A place cross-sectional schematic among Fig. 1;
Fig. 3 measures aperture miking power unit clamp detection aperture miking power example schematic;
Fig. 4 is an aperture milscale structural representation.
Among the figure: 1, chassis 2, test arm 3, test arm bolt 4, fastening frame 5, trip bolt 6, digital display push-and-pull dynamometer
Embodiment: measure aperture miking power unit clamp, it is characterized in that being made up of chassis, three test arms, three test arm bolts, three fastening frames, three trip bolts and three digital display push-and-pull dynamometers, disk is processed on the chassis; Make the through hole that the aperture milscale is installed at the disc centre place; The size of through hole manufactures series according to the specification of aperture milscale, and the edge on the disk one side makes three recesses that test arm is installed of even distribution, in recess, makes a threaded hole respectively; The test arm xsect is processed I shape; The fastening frame xsect is processed the I shape hole that cooperates with digital display push-and-pull test arm xsect near an end place, and the fastening frame xsect is processed the through hole that cooperates with dynamometer near other end place, on the fastening frame end face of through hole one side, makes the threaded hole that cooperates with trip bolt; Threaded hole communicates with through hole; Three test arms are contained in respectively in the recess on chassis and use the test arm bolted, make test arm upper surface and chassis upper surface in a plane, three fastening frames are contained in respectively on three test arms; Be slidingly matched, three digital display push-and-pull dynamometers be contained in respectively on three fastening frames fix with trip bolt.
With the instance of measuring aperture miking power unit clamp detection aperture miking power: select the chassis of different through holes for use according to aperture milscale specification, the aperture milscale is contained in the through hole on chassis, make the aperture milscale automatic; Adjust the distance of fastening frame again, the measuring head of digital display push-and-pull dynamometer is fully contacted with the measuring claw of aperture milscale, measuring error is reduced to minimum; Simultaneously, three digital display dynamometers are transferred to " 0 " position after, the measurement mechanism of rotation aperture milscale; Impel three measuring claws to move; Promote the measuring head of digital display dynamometer, make it the generation of digital display dynamometer and warn, when device for measuring force sends three soundings sound; At this moment the displayed value of digital display dynamometer is the dynamometry value of aperture milscale, should in the scope of national metrological verification regulations regulation, (10～35) N be qualified.This clamp structure is simple, and is easy to operate, simultaneously in 360 ° of scopes at any angle ergometry can measure.
