VOCATIONAL INTEREST BASIS SK – KD 06 MEASURING TOOLS APPLIES MECHANIC MEASURE DEVICES VOCATIONAL INTEREST BASIS SK – KD 06

PURPOSE OF LEARNING ACTIVITY Student can apply mechanic measuring instrument Student can calculate result of measuring instrument measure of mechanic. Teknologi dan Rekayasa

Mechanic Measuring Instrument 1. Ruler Ascertains ruler to stay as near by possible with equiamplitude surface of substance measured. Read of measure scale at ruler must be vertical with plane surface measured Teknologi dan Rekayasa

Mechanic Measuring Instrument 2. Rectangle Ruler Usage of rectangle ruler is done by ascertaining is wrong one divisions becomes reference. Then pastes up powerfully boom at the reference plane, Gives attention to its the shavings side Teknologi dan Rekayasa

Mechanic Measuring Instrument 3. Straightedge Pastes up straightedge above the equiamplitude surface to know its the un-flatness or aberration Teknologi dan Rekayasa

Mechanic Measuring Instrument 4. Meter Band Way of using it is by hooking correlating nose from plane roll, then draws meter sufficiently below(under the meter length ( usually maximum length written at body meter) Teknologi dan Rekayasa

Mechanic Measuring Instrument 5. Protractor Protractor is applied by gluing the device at substance which will be measured. Determines one points as one of fiducial point Teknologi dan Rekayasa

Mechanic Measuring Instrument 6. Screw Pitch Gauge Gauging process is done by some times by choosing correct measure shavings when paired with form of nut screw or bolt. Teknologi dan Rekayasa

Mechanic Measuring Instrument 7. Vernier calipers To get good gauging result need to be paid attention position of gauging must be vertical with work substance, hygiene of measuring instrument and substance measured and accuracy in scale read. Teknologi dan Rekayasa

Mechanic Measuring Instrument Calibrates vernier calliper Investigates density of external diamter jaw to light passing jaw Investigates inner diameter density Teknologi dan Rekayasa

Mechanic Measuring Instrument Investigates metering rod diamter in Teknologi dan Rekayasa

Mechanic Measuring Instrument Way of doing gauging External diameter gauging Teknologi dan Rekayasa

Mechanic Measuring Instrument Inner diameter gauging Depth gauging Teknologi dan Rekayasa

Mechanic Measuring Instrument Way of using Firstly, shift slide caliper according to its the requirement and breach-block screw key Teknologi dan Rekayasa

Mechanic Measuring Instrument Sees number zero at second caliper vernier scale, point searching where number at scale under vernier caliper as of line with number at metering rod scale and read result of his its. Teknologi dan Rekayasa

Mechanic Measuring Instrument 8. Dial indicator In its use, dial indicator cannot stand up x'self, causing requires buffer joint and block magnet Teknologi dan Rekayasa

Mechanic Measuring Instrument Way of reading dial indicator Minute hand shows line to 6, result of its the read is 6 x 0,01 = 0,06 mm. Whereas hours hand refers line to 3, mean minute hand has rotated 3 times. Result of gauging of is 3 + 0,06 = 3,06 mm Teknologi dan Rekayasa

Mechanic Measuring Instrument 10. Micrometer Usage Enters micro meter at substance which will be measured Rotary ratcher stopper until says “ clicks”. Locks ( lock clampI and disengaged of micro meter from work substance Teknologi dan Rekayasa

Mechanic Measuring Instrument Reads result of gauging Mikrometer Distance every stripe to horizontal line at outer sleeve is 1 mm, and distance every stripe below under line is 0,5 mm. At scale thimble every its the value stripe 0,01 mm. Result of gauging at micrometer is number of third reads of the scale. Teknologi dan Rekayasa

Mechanic Measuring Instrument Reads result of gauging Mikrometer Scale above line 5,00 mm Skala below under line 0,00 mm Skala thimble 0,20 final mm 5,20 mm Teknologi dan Rekayasa

Mechanic Measuring Instrument 9. Dial bore indicator 9. Dial bore indicator Cylindrical diameter measure with slide rule, for example obtained result of gauging : 75,40 mm. SPACER Replacement rod DIAL GAUGE Select and tide replacement rod which length bigger than result of gauging, for example 76 mm. Teknologi dan Rekayasa

Mechanic Measuring Instrument Length measure replacement rod with external micrometer and labours needle dial non movable gage, for example obtained result of gauging = 76,20 mm Teknologi dan Rekayasa

Mechanic Measuring Instrument Enters replacement rod into aperture ( platen), shakes down peduncle bore gage dextrorse and sinistrorse like at drawing 30 until obtained by the biggest aberration ( position of perpendicular) Teknologi dan Rekayasa

Mechanic Measuring Instrument Read level of aberration posed at dial gage, for example obtained by 0,13 mm. Level of platen diameter is difference between result of measurement of lengths replacement rod with level of aberration of needle bore gage. So platen diameter = 76,20 – 0,13 = 76,07 mm. Teknologi dan Rekayasa

Mechanic Measuring Instrument 11. Usage of torque key X 90 Teknologi dan Rekayasa

Mechanic Measuring Instrument Torque moment is applied together with key shock put down at the end of his its. Enters shock key at nut or bolt which will be tightened, draws its the handle until needle shows number moment wanted or happened click noise to lock moment of click type Teknologi dan Rekayasa

Mechanic Measuring Instrument Enters thickness gauge among aperture or gap until felt congested, if has not oppressed, shavings searching thickness gauge which is compatible until felt congested 12. Thickness Gauge Teknologi dan Rekayasa

Mechanic Measuring Instrument Way of using this very simple device, that is placing carriage of plane place. Device tide at wheel axis and result read from gauging 13. Tracking Teknologi dan Rekayasa
