Abstract

Nrụpụta nkenke nke mpempe akwụkwọ aluminom (<3mm) na-eche nnukwu ihe ịma aka ọrụ ihu. Ọmụmụ ihe a na-atụnyere sistemụ ndọta na pneumatic clamping n'okpuru ọnọdụ igwe igwe CNC na-achịkwa. Usoro nnwale gụnyere nkwekọ ike njigide, nkwụsi ike nke okpomọkụ (20°C–80°C), ịma jijiji, na mgbagha n'elu. Igwe ikuku pneumatic na-echekwa 0.02mm flatness maka mpempe akwụkwọ 0.8mm mana achọrọ ebe mkpuchi na-emebibeghị. Igwe ọkụ eletrik nyere ohere ịnweta 5-axis ma belata oge ntọlite ​​site na 60%, mana mmiri mmiri na-akpata kpatara kpo oku mpaghara gafere 45°C na 15,000 RPM. Nsonaazụ na-egosi sistemu agụụ na-ebuli elu elu maka mpempe akwụkwọ> 0.5mm, ebe ngwọta ndọta na-emezi mgbanwe maka imepụta ngwa ngwa. Mmachi na-agụnye ụzọ ngwakọ anwaleghị yana ihe ndị ọzọ dabere na nrapado.

1 Okwu mmalite

Ụlọ ọrụ na-arụ ọrụ ike nke aluminom dị mkpa sitere na mbara igwe (akpụkpọ anụ fuselage) gaa na ngwá electronic (ichepụta ikpo ọkụ). Agbanyeghị, nyocha ụlọ ọrụ 2025 na-ekpughe 42% nke ntụpọ ziri ezi sitere na mmegharị ọrụ n'oge igwe. Mkpịsị usoro ihe eji eme ihe na-agbagọkarị mpempe akwụkwọ sub-1mm, ebe usoro dabere na teepu enweghị isi ike. Ọmụmụ ihe a na-akọwapụta ihe ngwọta abụọ dị elu: electromagnetic chucks leveraging remanence control technology and pneumatic system with multi- zone vacuum control.

2 Usoro

2.1 Nleba anya

• Ihe onwunwe: 6061-T6 aluminum mpempe akwụkwọ (0.5mm / 0.8mm / 1.2mm)

• Ngwa:

  • Magnetik: GROB 4-axis electromagnetic Chuck (0.8T ubi ike)

  • Pneumatic: SCHUNK vacuum efere nwere akụkụ 36

• Nnwale: Mbelata dị n'elu (laser interferometer), onyogho thermal (FLIR T540), nyocha vibration (3-axis accelerometers)

2.2 Usoro nnwale

1. Static Stability: Tulee ngbanwe n'okpuru ike mpụta 5N

2. Ịgba igwe okpomọkụ: Dekọọ gradients okpomọkụ n'oge igwe nri (Ø6mm igwe ihe njedebe, 12,000 RPM)

3. Mgbagwoju anya na-agbanwe agbanwe: Kwupụta njupụta nke ịma jijiji na ugboro ugboro (500-3000 Hz)

3 Nsonaazụ na nyocha

3.1 arụrụ ọrụ mmachi

Ọnụọgụ 1: A na-edobe sistemu oghere <5μm n'elu mgbanwe ihu n'oge egwe ọka, ebe ndọta clamping gosiri 0.12mm onu ebuli n'ihi thermal mgbasawanye.

3.2 Njirimara ịma jijiji

Pneumatic chucks na-ebelata harmonics site na 15dB na 2,200Hz - dị oke mkpa maka ịrụ ọrụ nke ọma. Njide magnetik gosipụtara njupụta dị elu 40% n'ọtụtụ ntinye aka ngwa.

4 Mkparịta ụka

4.1 Teknụzụ azụmaahịa

• Uru nke Pneumatic: Nkwụsi ike dị elu yana ịma jijiji dabara ngwa nnabata dị elu dị ka ntọala akụrụngwa ngwa anya.

• Edge magnetik: Nhazigharị ngwa ngwa na-akwado gburugburu ụlọ ahịa ọrụ na-ejikwa nha nha dị iche iche.

Mmachi: Nnwale ewepụrụ akwụkwọ mpempe akwụkwọ gbawara agbawa ma ọ bụ mmanu ebe arụmọrụ oghere na-agbada> 70%. Ngwakọta ngwọta na-akwado ọmụmụ ihe n'ọdịnihu.

5 Nkwubi okwu

Maka igwe mpempe akwụkwọ aluminom dị mkpa:

1. Pneumatic na-arụ ọrụ na-ebuga nkenke dị elu maka ọkpụrụkpụ> 0.5mm na-enweghị ihe mgbochi.

2. Sistemu magnetik na-ebelata oge na-adịghị egbu oge site na 60% mana ọ chọrọ atụmatụ coolant maka njikwa okpomọkụ

3. Nhọrọ kacha mma dabere na mkpa mbupu yana ihe achọrọ nnabata

Nchọpụta ga-eme n'ọdịnihu kwesịrị inyocha mgbachi ngwakọ na-agbanwe agbanwe yana atụmatụ elektrọnmagnet nnyonye anya dị ala.
