Iyo Digital Torque Wrench Inoshanda sei: Kubva Sensor kuenda Kuratidza

Dhijitari torque wrench inoyerwa torque pamagetsi uye inopa mhedzisiro pachiratidziri. Mune yakajairika dhizaini-yakavakirwa dhizaini, kurodha wrench kunokonzera diki elastic deformation mune inonzwa chinhu. Mageji eStrain anopindura kune deformation, achigadzira chiratidzo chemagetsi chekuti mamiriro emagetsi, dhijitari uye shandura kuita torque kuverenga. Chiratidziro ndiyo nhanho yekupedzisira yeiyi nzira yekuyera. Kurongeka kwayo, kuverenga kwepamoyo uye kuchengetwa kwepamusoro kunogona kutsanangura zvinhu zvakasiyana, saka kunzwisisa kunobva kukosha kwega kwega kunobatsira kutsanangura kuti chishandiso chiri kuratidza chii.

Mashandisirwo eTorque Inoburitsa Sensor Signal

Elastic Deformation Mukati meChishandiso

Kuisa simba pamubato kunogadzira torque pamusoro peiyo axis yefastener. Mukati mechipanera, mutoro iwowo unoburitsa diki deformation muchimiro chinoitakura. Chinhu chinonzwa chakagadzirirwa kupindura zvinofanofungidzira mukati mechikamu chekushanda, ichibvumira chiridzwa kuti chienderane nemhinduro yacho kune torque yakashandiswa.

Iyi elastic deformation: chinhu chinowanzo dzokera kune chimiro chayo chepakutanga kana mutoro wabviswa. Hazvirevi kuti chipanera chinofanira kukotama chichioneka. Kufamba kunodiwa pakuyera kunogona kunge kuri kudiki kuti uone.

Iyo mechanical kuronga inosiyana pakati pemagadzirirwo. Sensor inogona kupindura pakukotama kana torsional strain, zvichienderana nekuti chishandiso chinotakura sei uye kunzwa mutoro. Iyo sensing element uye geji yekuisa inotevera iyo mechanic dhizaini.

Maonero eStrain Gauge Inoona Iyo Deformation

Bonded strain geji inoshandura kusamira kwemagetsi sezvo pasi payo painotambanuka kana kumanikidza. Kuronga mageji mudunhu rebhiriji kunobvumira kuyerwa kwemagetsi kuona shanduko diki dzekupikisa semutsauko wevolti.

Kubuda kwebhiriji kunoshanduka pamwe nekuremerwa pachinhu chekunzwa. Nekuyera iyo mhinduro, zvemagetsi zvinogona kutevera torque iri kuiswa. Iyo geji pachayo haidi chinongedzo kana kufamba kunooneka kuratidza shanduko.

Panguva ino, chishandiso chine mhinduro yemagetsi pakurodha. Haisati yava nenhamba yakapedzwa inoratidzirwa muN·m.

Maitiro eMagetsi Anoshandura Chiratidzo kuita Digital Data

Bridge Excitation, Amplification uye Sefa

A bridge-based sensor inoda kunakidzwa kwemagetsi kuitira kuti kusandura kwayo kugone kuburitsa kubuda kunoyerwa. Chiratidzo chinobuda chinofanirwa kunge chakakodzera chikamu chinotevera cheyero system.

Amplification inounza chiratidzo chidiki muchikamu chinobatsira pakuyera. Kusefa kunobatsira kudzora zvisingadiwe masaini zvikamu, zvakaita seruzha rwemagetsi, zvinogona kukanganisa mhedzisiro. Pamwe chete nekunakidzwa, aya mabasa anogadzirira iyo sensor inobuda yekushandura.

Aya matanho anoshanda, kwete hazvo akapatsanura zvikamu pabhodhi redunhu. Mimwe michina inosanganisa akati wandei mabasa mukati memusanganiswa wedunhu. Kuita kwavo kunosanganisirawo sarudzo nezve kumhanya kwekupindura uye ruzha, saka kuratidzwa kwakajeka kwega hakuburitse maitirwo emagetsi epasi pekuchinja mutoro.

Analogi-ku-Digital Shanduko

Analog-to-digital converter, kana ADC, inomiririra iyo yakagadziriswa magetsi chiratidzo senhamba data. Iyo processor inogona kushandisa iyo data kuverenga kukosha kwetorque uye kutonga kuratidzwa.

Digitization inoita kuti kuyerwa kuvepo kwekugadziriswa kwenhamba. Chiridzwa chacho chinogona kushandisa zviyero zvinotevedzana kugadzirisa chiratidziro mhenyu, kuchengetedza chakayerwa kana kuenzanisa kuverenga nechinangwa chakasarudzwa. Iyo inoshandura inopa iyo data; iyo gadziriso inosarudza kuti iyo data inoshandiswa sei.

Sei Dhijitari Dhata Inova Torque Kuverenga

Inobatanidza iyo Sensor Output kune inozivikanwa Torque

Kubuda kwechishanduri hakusi iko kukosha muNewton-metres. Iyo yakaunganidzwa yekuyera sisitimu inoda hukama pakati pemhinduro yayo yemagetsi uye torque inozivikanwa.

Hukama ihwohwo hunobvumira chiridzwa kushandura shanduko mukubuda kwe sensor kuita shanduko mune yakaratidzwa torque. Calibration inofanidza zviratidzo zvechiridzwa nereferensi maitiro pasi pemamiriro akatarwa. Apo kugadziridzwa kunodiwa, chiito chakasiyana; kungoita calibration hakungogadzirise chiridzwa.

Iko kutendeuka kunogona kushandisa akachengetwa coefficients kana kumwe kugadzirisa kwakakodzera dhizaini. Chero iko kuitiswa, hukama hunoshanda kune yakazara kuyerwa sisitimu, kubva pane yakatakurwa chinhu kusvika kune chiratidzo. A raw converter count inova yakakosha chete kana ichienderana nehuwandu huri kuyerwa.

Zero Offset uye Engineering Units

Iyo yekuyera sisitimu inogona kuve neyakagadziriswa: inobuda isina nzero kunyangwe iyo yaitarisirwa kuisirwa mutoro uri zero. A zeroing basa rinogadza referensi inoshandiswa pakuverenga kunotevera, ichitevera mirairo yechishandiso.

Zeroing uye calibration inogadzirisa mibvunzo yakasiyana. Kumisikidza zero isina kurodzwa hazviratidzi kuti chiridzwa chinoverenga nemazvo mukati me torque yayo yese. Offset inotsanangura kukanganisa kwekutanga; kuwana inotsanangura chiyero chemhinduro. Kugadzirisa pekutangira chete hakugadzirisi hukama mukati mechiyero chekuyera.

Kana chiridzwa chasarudza torque, chinogona kuratidza huwandu uhu muchikamu chinotsigirwa senge N · m kana ft · lb. Kushandura chikwata kunoshandura nhamba inomiririra yehuwandu. Haisi kugadzira torque yakasiyana yemuviri pajoinhi.

Zvinoratidzwa Chiratidziro Panguva uye Mushure mekusimbisa

Rarama Torque, Peak Torque uye Iyo Target Setting

A target setting ndiyo kukosha kwaiswa pakushanda. Kuverenga mhenyu kunomiririra kuyerwa torque sezvo mutoro unochinja. Kuverenga kwepamusoro kunochengeta kukosha kwepamusoro kwakayerwa kwakatorwa panguva yekuyera kutenderera kwechiridzwa.

Tsika idzodzo dzinoshanda zvinangwa zvakasiyana. Chinangwa chinoudza mushandisi kuti chii chakasarudzwa; hausi humbowo hwekuti torque iyi yakatoshandiswa. Peak yakachengetwa inogona kuramba ichionekwa mushure mekunge simba radzikiswa, nepo chiratidzo chekutevera chinotevera kuyerwa kwekuchinja.

IweBar's ratchet digital torque wrench inonyora PEAK uye TRACK modhi, P0-P9 torque presets, uye zvinonzwika uye zvinoonekwa chenjedzo. Aya maficha anotsanangura kuti chishandiso chinopa sei uye kushandisa ruzivo rwekuyera. Yambiro haifanire kuturikirwa sekumira otomatiki mukushandisa simba.

Paunenge uchiongorora YouBar's digital torque wrench renji, enzanisa mabasa ekuratidzira kune ruzivo rwaunoda kushanda. Nezvinodiwa zvinopfuura zvakaburitswa zvakatemwa, kukurukura kuyerwa uye kuratidza zvinodiwa kune imwe modhi.
