Ɛha yi, yɛde Linear motion actuator, TMSL135-CM a data te sɛ nea edidi so yi ba:

Ɔkwan a wɔfa so hu pɛpɛɛpɛyɛ ma Linear motion actuator
1.Positioning pɛpɛɛpɛ detection
Yɛ susudua nhyehyɛe a wode laser interferometer bedi dwuma, siesie reflector no wɔ platform slider no so, na fa detection points pii si motion axis no so (te sɛ susudua biako 50mm biara). Sɛ asɛnka agua no kɔ beae a wɔde wɔn ani asi so no sɛnea akwankyerɛ no kyerɛ wie a, kyerɛw twe a wɔtwe wɔn ho fi ankasa displacement a laser interferometer no da no adi ne akwankyerɛ bo no ntam, na bu deviation bo a ɛsen biara wɔ stroke no nyinaa mu, a ɛyɛ gyinabea no pɛpɛɛpɛ. Sɛ nhwɛsoɔ no, wɔ semiconductor detection platform a ɛwɔ 300mm stroke mu no, sɛ deviation a ɛkyɛn so no yɛ ± 0.003mm a, ɛdi micrometer level positioning ahwehwɛdeɛ no so. Wɔ sɔhwɛ mu no, ɛsɛ sɛ wɔde adwene si ɔhyew a atwa yɛn ho ahyia no so (a wɔhwɛ so wɔ 20 ± 0.5℃) na wɔakwati ɔhyew mu nsakrae a ebetumi ama ɔhyew atrɛw na atwetwe akwankyerɛ keteke no na aka data no.

2.Repetitive gyinabea pɛpɛɛpɛ detection
Paw beae bi a wɔahyɛ da ayɛ (mpɛn pii no mfinimfini) wɔ akwantu nhyehyɛe no mu, na ma asɛnka agua no nsan nyɛ adeyɛ koro no ara de nkɔ saa beae no (mpɛn dodow a wɔkamfo kyerɛ sɛ Ɛboro 30 anaasɛ ɛne no yɛ pɛ). Fa grating ruler anaa high-precision dial gauge di dwuma de kyerɛw gyinabea ankasa wɔ bere biara a woadu akyi. Bu standard deviation a ɛwɔ saa data yi mu, a ɛyɛ repeatability accuracy. Sɛ standard deviation a ɛwɔ 30 susuw wɔ mfiri adwinnade platform pɔtee bi so yɛ 0.001mm a, ɛkyerɛ sɛ repeatability stability a ɛkyɛn so. Ansa na wɔbɛsɔ ahwɛ no, ɛsɛ sɛ asɛnka agua no tu mmirika a wɔmfa adesoa biara nka ho simma 10 na ama ayɛ hyew na wɔatew nkɛntɛnso a motor no hyew a ɛkɔ soro nya wɔ transmission pɛpɛɛpɛ so no so.

3.Straightness mfomso a wohu
Siesie pɛpɛɛpɛ level a ɛne axis of motion a ɛwɔ base no so no hyia, fa lever dial gauge si slider no so, na yɛ contact wɔ gauge ti no ne level no adwumayɛbea no ntam. Sɛ asɛnka agua no tu ahoɔhare a ɛkɔ so daa a, dial indicator pointer no swing amplitude no da tẽẽyɛ a ɛtwetwe no adi, a wɔakyekyɛ mu ayɛ no horizontal direction (benkum-nifa so swing) ne vertical direction (ɔsoro ne fam nsakrae). Sɛ nhwɛso no, sɛ mfomso a ɛda hɔ tẽẽ a ɛwɔ laser twa asɛnka agua no so boro 0.02mm/m a, ebetumi ama nsusuwii ahorow a ɛkɔ fam aba wɔ nea wɔatwa no so. Bere a wɔreyɛ sɔhwɛ no, ɛho hia sɛ wɔhwɛ hu sɛ wɔde flat ruler no ahyɛ mu yiye na wɔakwati sɛ n’ankasa bɛdan akɔ nea efi mu ba no so.

4.Stability sɔhwɛ bere a wɔyɛ adwuma
Fa vibration sensors hyehyɛ platform no so na kyerɛw vibration acceleration values ​​wɔ ahoɔhare ahorow mu (mpɛn pii no mm/s 2). Wɔ ahoɔhare kɛse-dwumayɛ mu (te sɛ 300mm/s), sɛ wosow bo no kɔ soro mpofirim a, ebetumi afi synchronous belt no nhyɛso a ɛnteɛ anaasɛ akwankyerɛ keteke kwan so slider no asɛe. Afei nso, wobetumi ahu dede a ɛnyɛ ne kwan so bere ne bere mu denam aso a wohu so, na wobetumi de infrared thermometer ahwɛ sɛnea motor ne screw bearing ahorow no hyew te. Sɛ ɔhyew a ɛkɔ soro wɔ ɔfã pɔtee bi boro digrii 40 , ebetumi ama adwumayɛ akyɛ esiane srade a wɔmfa nhyɛ mu yiye nti, na ɛbɛka pɛpɛɛpɛyɛ no wɔ ɔkwan a ɛnteɛ so.

5.Accuracy verification wɔ adesoa tebea horow ase
Yɛ adwuma ankasa ho mfonini (te sɛ fixtures a emu duru a ɛne no hyia a wode besisi hɔ), san yɛ atifi hɔ gyinabea no na san yɛ gyinabea a wohu no bio. Platform ahorow bi du pɛpɛɛpɛyɛ gyinapɛn ahorow ho bere a wɔayi nneɛma afi mu no, nanso deformation ba esiane akwankyerɛ keteke kwan no a ɛnyɛ den sɛnea ɛsɛ bere a wɔde nneɛma ahyɛ mu akyi nti, na ɛde deviation kɔ soro. Sɛ nhwɛsoɔ no, sɛ nkyerɛaseɛ fã a ɛwɔ aduruyɛ CT mpa so no soa 150kg a, sɛ gyinabea pɛpɛɛpɛyɛ sesa fi ± 0.01mm bere a wɔayi afi mu kɔ ± 0.03mm a, ɛho hia sɛ wɔhwɛ sɛ ebia ɛsɛ sɛ wɔhyɛ akwankyerɛ keteke mmoa nhyehyɛe no mu den anaa.
