Description
Technical field
The utility model relates to a kind of bearing technical field of measurement and test, particularly relates to a kind of bearing measuring outside micrometer.
Background technology
Micrometer caliper, also known as milscale, spiral dial gauge, micrometer, is the instrument of the measurement length more accurate than vernier caliper, and survey length with it and can be accurate to 0.01mm, measurement range is several centimetres.Its part is processed into the screw thread that pitch is 0.5mm, and when it rotates in the swivel nut of fixed sleeving B, will advance or retreat, moving casing C and screw rod are connected, and its periphery is divided into 50 lattices.The whole number of turns of bolt rotary is gone to measure by the groove of interval 0.5mm on fixed sleeving, and gone to measure by the groove of moving casing periphery less than the part of a circle, final measurement needs to estimate to read a decimal.
Micrometer caliper is also milscale, is a kind of precision measuringtoll.Milscale also claims micrometer caliper.Micrometer caliper is that the principle of amplifying according to spiral is made, and namely screw rod rotates a circle in nut, and screw rod just advances or the distance of a slow astern pitch along rotation direction.Therefore, the slight distance of movement in the axial direction, just can show with reading circumferentially.The pitch of the accurate thread of micrometer caliper is 0.5mm, and movable mark has 50 evenly divideds, and movable mark rotates a circle, and micrometric screw can advance or retreat 0.5mm, therefore rotates each little calibration, is equivalent to micrometric screw and advances or postpone 0.5/50=0.01mm.Visible, each little calibration of movable mark represents 0.01mm, so micrometer caliper can be accurate to 0.01mm.One is read owing to estimating again, thousand points of positions of millimeter can be read, therefore have another name called milscale, during measurement, when gage button and micrometric screw close up, if the zero point of movable mark overlaps with the zero point of fixing scale just, screw out micrometric screw, and the two ends of the face making gage button and micrometric screw just in time contact measured length, attention firmly can not rotate otherwise measure inaccurate, slowly rotate the ratchet turning handle in face, left and right until the sound of transaudient click click when touching measuring surface, the distance that so micrometric screw moves right is exactly surveyed length at once.The whole millimeter of this distance reads by fixing on scale, and fraction part is then read by movable mark.
Current existing outside micrometer is not easy location when measuring bearing, causes the external diameter of measurement to have larger error.
