I. Mapangidwe a Core ndi Mfundo Yoyendetsera Ntchito ya Cam Indexer
Cholozera cha cam ndi njira yolondola yomwe imasinthira kusuntha kosalekeza kukhala kusuntha kwapakatikati. Chiyambi chake chimakhala ndi zigawo zitatu:
1. Kamera yolowetsa: Nthawi zambiri imakhala yozungulira kapena yathyathyathya, yokhala ndi makina opindika (monga curve yosinthidwa). Liwiro lake lozungulira limayambira 200-600 rpm (Source: "Mechanical Design Handbook," Edition Yachisanu ndi chimodzi).
2. Wodzigudubuza wotsatira: Ikanikizidwa motsutsana ndi mbiri ya cam ndi kasupe kapena mphamvu yokoka, imatembenuza mayendedwe opindika a kamera kukhala oscillation wapakatikati.
3. Disiki yotulutsa: Yolumikizidwa mwamphamvu ndi otsatira, imathandizira kulondolera bwino ndikuyika, ndikubwereza mpaka ± 30 arc masekondi (onani catalog ya Sankyo Machinery).
Mfundo yogwiritsira ntchito ndi yakuti pamene cam imazungulira mofulumira, mbiri yokhotakhota imakankhira chodzigudubuza, zomwe zimapangitsa kuti disc yotulutsayo imalize "kuzungulira{0}}kupumula". Mwachitsanzo, zolozera zinayi-zimayima pamadigiri 90 aliwonse pozungulira. Pa kupuma uku, "gawo logwira" la cam limatsimikizira kukhazikika.
II. Makhalidwe Akuluakulu Aukadaulo ndi Zomwe Zimagwira Ntchito
1. Mapangidwe a Cam Curve:
- Mipendero wamba imaphatikizapo sine yosinthidwa ndi trapezoidal yosinthidwa. Ma curve osiyanasiyana amakhudza kuthamanga komanso kugwedezeka. Mwachitsanzo, mathamangitsidwe apamwamba a sine curve ndi 1.8 m/s² (Cam Mechanism Design Manual), kupangitsa kuti ikhale yoyenera-zothamanga kwambiri.
2. Kuwongolera Mwatsatanetsatane:
- Vuto lolondolera makamaka limachokera ku kulondola kwa makina a cam (ayenera kukumana ndi mulingo wa IT5) ndi chilolezo chodzigudubuza (chomwe chimalangizidwa Chochepera kapena chofanana ndi 0.02 mm).
3. Katundu:
-Makokedwe ake ndi ogwirizana ndi kukula kwa indexer. Mwachitsanzo, torque yaikulu ya DSF-80 ndi 80 N · m (Taiwan Tanzi Precision Machinery Parameter Table).
III. Mapulogalamu Odziwika ndi Zosankha Zosankha
1. Mizere Yopangira Makina: Matebulo owonetsera omwe amagwiritsidwa ntchito polumikizira ndi poyang'anira malo amafunikira kubwereza kwambiri (mwachitsanzo, ± 15 arc masekondi a zida za semiconductor).
2. Makina Opaka: Oyenera kugwiritsa ntchito sing'anga ndi otsika-mapulogalamu othamanga (Ochepera kapena ofanana ndi 300 rpm), amafuna kuvala-zinthu zosagwira ntchito (monga pamwamba{4}}zitsulo za carburized S45C).
3. Zosankha Zofunika Kwambiri:
Chiwerengero cha zolozera (masiteshoni 4-24 ndizofala), katundu wosinthika (malola 20% malire otetezedwa), ndi kutentha kozungulira (madigiri -10 mpaka 60 digiri ndiye mulingo woyenera).
Chidziwitso Choonjezedwa: Poyerekeza ndi ma servo indexing solutions, ma cam indexers amapereka ubwino wa zero backlash ndi kukonza{{0}ntchito yaulere, koma amapereka kusinthasintha kochepa ndipo motero ndi oyenera pakupanga zinthu zambiri zomwe zimafuna kuti zigwire ntchito nthawi yayitali-yokhazikika.
