Positioning referensi uye zvigadziriso uye kushandiswa kweanowanzo shandiswa geji

1, pfungwa yekumisa bhenji

Iyo datum ndiyo poindi, mutsara, uye pamusoro apo chikamu chinotarisisa nzvimbo yemamwe mapoinzi, mitsetse, uye zviso. Chirevo chinoshandiswa pakumisikidza chinodaidzwa kuti chirevo chekumisikidza. Position inzira yekuona nzvimbo chaiyo yechikamu. Maburi maviri epakati anopiwa pane ekunze cylindrical grinding shaft parts. Kazhinji, shaft inotora maviri epamusoro mabhanhire, uye nzvimbo yekumisikidza inzvimbo yepakati inoumbwa nemakomba maviri epakati, uye workpiece inotenderera inoumbwa kuita cylindrical pamusoro.CNC machining chikamu

2, gomba repakati

Iyo general cylindrical grinding process inotariswa pane general shaft zvikamu, uye dhizaini yepakati gomba inowedzerwa kune chikamu chekudhirowa senzvimbo yekumisikidza. Pane nzira mbiri dzemhando dzepakati maburi. Iyo A-mhando yepakati buri i60 ° cone, inova chikamu chekushanda chepakati buri. Inotsigirwa nepamusoro 60 ° cone kuisa pakati uye kutsungirira simba rekukuya uye simba rekushanda. Iyo diki yecylindrical yakaboora pamberi pe60 ° cone inochengetera mafuta ekudzikisa kukweshera pakati pemuromo nepakati peburi panguva yekukuya. A B-mhando yepakati buri ine 120 ° yekudzivirira koni, iyo inodzivirira 60 ° conical mipendero kubva kumapundu, yakajairwa mumabasa ekushanda ane hunyanzvi hwepamusoro uye matanho akareba ekugadzirisa.stamping chikamu

3. Zvido zvehunyanzvi zvegomba repakati

(1) The roundness tolerance of the 60° cone is 0.001 mm.

(2) Iyo 60 ° conical pamusoro ichaongororwa negeji yemavara nzira, uye nzvimbo yekubata ichave yakakura kupfuura 85%.

(3) Iyo coaxial kushivirira kwepakati gomba kumativi ese ari maviri ndeye 0.01mm.

(4) Kushata kwepamusoro kweiyo conical surface ndeye Ra 0.4 μm kana pasi, uye hapana chakaremara senge maburrs kana mabumps.

Kuzadzisa zvinodikanwa zvegomba repakati, gomba repakati rinogona kugadziriswa nenzira dzinotevera:

1) Kukuya buri repakati nedombo remafuta uye vhiri rekukuya rabha

2) Kukuya buri repakati nesimbi yakakandwa tip

3) Kukuya buri repakati negumbo remukati

4) Kuwedzerwa kwegomba repakati neine quadrangular cemented carbide tip

5) Kukuya buri repakati nepakati nepakati

4, pamusoro

Mubato wepamusoro iMorse cone, uye saizi yetipi inoratidzirwa muMorse taper, senge Morse No. 3 tip. Iyo yepamusoro igadziriso yepasirese iyo inoshandiswa zvakanyanya mukukuya cylindrical.

5, mandrels akasiyana

Iyo mandrel chigadziriso chinoshamisa chekusunga seti yezvikamu kuti zvisangane nezvinodiwa zvekugaya kwekunze kwechikamu.chikamu chepurasitiki

6, vernier caliper kuverenga

Iyo vernier caliper ine nzara yekuyeresa, mutumbi wemutongi, vernier yakadzika geji, uye fastening screw.

7, micrometer kuverenga

Iyo micrometer ine mutongi, anvil, micrometer screw, yekuvhara mudziyo, yakagadziriswa sleeve, inosiyanisa humburumbira, uye simba-kuyeresa mudziyo. Nzvimbo yekuyera ye micrometer inofanira kucheneswa, uye zero ye micrometer inofanira kuongororwa isati yashandiswa. Chenjerera kune chaiyo yekuyera kumira pakuyera.
