Ukubeka ireferensi kunye nezixhobo kunye nokusetyenziswa kweegeji ezisetyenziswa ngokuqhelekileyo

1, ingqikelelo yokubeka ibhentshimakhi

I-datum yingongoma, umgca, kunye nomphezulu apho inxalenye isetyenziselwa ukumisela indawo yezinye iingongoma, imigca kunye nobuso. Isalathiso esisetyenziselwa ukumisa sibizwa ngokuba yireferensi yokubeka. Ukubekwa yinkqubo yokumisela indawo echanekileyo yenxalenye. Imingxuma emibini yeziko inikezelwa kwiindawo zangaphandle ze-cylindrical grinding shaft. Ngokuqhelekileyo, i-shaft ithatha ii-clamps ezimbini eziphezulu, kwaye ireferensi yokubeka indawo yi-axis esembindini eyenziwe yimingxunya emibini ephakathi, kwaye i-workpiece yenziwe ngokujikelezayo ibe yi-cylindrical surface.cnc machining inxalenye

2, umngxuma ophakathi

Inkqubo yokugaya i-cylindrical ngokubanzi iqwalaselwa kwiindawo ze-shaft jikelele, kwaye umngxuma weziko loyilo longezwa kwinxalenye yomzobo njengesalathisi sokumisa. Kukho iikhrayitheriya ezimbini zemingxuma esembindini eqhelekileyo. I-A-uhlobo umngxuma embindini yi cone 60 ° leyo inxalenye yokusebenza umngxuma embindini. Ixhaswa yi-cone ephezulu ye-60 ° ukuseta iziko kunye nokumelana namandla okugaya kunye nobunzima bomsebenzi. I-cylindrical encinci ibhore ebusweni be-cone ye-60 ° igcina i-lubricant ukunciphisa ukukhuhla phakathi kwencam kunye nomngxuma ophakathi ngexesha lokusila. Uhlobo lwe-B-umngxuma ophakathi kunye ne-120 ° i-cone yokukhusela, ekhusela i-60 ° i-conical edges kwi-bumps, ixhaphake kwiindawo zokusebenza ezichanekileyo eziphezulu kunye namanyathelo okucubungula amade.isitampu inxalenye

3. Iimfuno zobugcisa zomngxuma ophakathi

(1) Ukunyamezelana okungqukuva kwe-cone ye-60 ° yi-0.001 mm.

(2) Umphezulu we-conical we-60 ° uya kuhlolwa ngendlela yokulinganisa umbala, kwaye umphezulu wokudibanisa uya kuba mkhulu kune-85%.

(3) Ukunyamezelana kwe-coaxiality yomngxuma ophakathi kwiziphelo zombini yi-0.01mm.

(4) Uburhabaxa bomphezulu we-conical surface yi-Ra 0.4 μm okanye ngaphantsi, kwaye akukho ziphene ezifana ne-burrs okanye i-bumps.

Ukuhlangabezana neemfuno zomngxuma ophakathi, umngxuma ophakathi ungalungiswa ngolu hlobo lulandelayo:

1) Ukugaya umngxuma ophakathi ngelitye leoli kunye nevili lokugaya irabha

2) Ukugaya umngxuma ophakathi kunye nentsimbi yentsimbi

3) Ukugaya umngxuma osembindini kunye nevili lokugaya elingaphakathi

4) Ukukhutshwa komngxuma ophakathi kunye ne-quadrangular cemented carbide tip

5) Ukugaya umngxuma ophakathi kunye ne-grinder yeziko lomgodi

4, phezulu

Umqheba ophezulu yi-Morse cone, kwaye ubukhulu bencam bubonakaliswa kwi-Morse taper, njenge-Morse No. 3 tip. Umphezulu ulungelelwaniso lwendalo yonke olusetyenziswa ngokubanzi kwi-cylindrical grinding.

5, mandrels ezahlukeneyo

I-mandrel yinto ekhethekileyo yokudibanisa isethi yamacandelo ukuhlangabezana neemfuno ezichanekileyo zokusila ngaphandle kwenxalenye.inxalenye yeplastiki

6, ukufundwa kwe-vernier caliper

Ikhalipha ye-vernier ibandakanya uzipho lokulinganisa, irula yomzimba, igeyiji yobunzulu be-vernier, kunye ne-fastening screw.

7, ukufunda ngemicrometer

I-micrometer iqukethe irula, i-anvil, i-screw ye-micrometer, isixhobo sokutshixa, umkhono osisigxina, i-cylinder yokwahlukana, kunye nesixhobo sokulinganisa amandla. Umphezulu wokulinganisa we-micrometer kufuneka ucocwe kwaye i-zero ye-micrometer kufuneka ihlolwe ngaphambi kokusetyenziswa. Nika ingqalelo kwisimo somlinganiselo esichanekileyo xa ulinganisa.
