Burg'ulash nima?
Teshikni qanday burg'ulash kerak?
Burg'ulashni qanday aniqroq qilish kerak?
Bu quyida juda aniq tushuntirilgan, keling, ko'rib chiqaylik.
1. Burg'ulashning asosiy tushunchalari
Umuman olganda, burg'ulash materiallar yuzasiga teshiklarni qayta ishlash uchun mashqlardan foydalanadigan qayta ishlash usulini anglatadi. Umuman olganda, burg'ulash mashinasida burg'ulash uchun buyumlar, burg'ulash bittasi bir vaqtning o'zida ikkita harakatni tugatishi kerak:
① Asosiy harakati, ya'ni, o'qning atrofida aylanadigan aylanma harakati (kesish harakati);
②skonary Harakat, ya'ni, mashqning yo'nalishi bo'ylab o'q uzilishiga (ozuqa harakati) yo'nalishi.
Burg'ulash paytida burg'ulash paytida, burg'ulash tarkibidagi kamchiliklar tufayli belgilar ish bilan ishlov berish sifatiga ta'sir qiluvchi mahsulotning qayta ishlangan qismlarida belgilar qoldiriladi. Ishlov aniqligi odatda IT10 darajasidan past, er yuzasi pürüzlülülülme qo'pol ishlov berish toifasiga tegishli bo'lgan ra12,5 mkm atrofida. .
1. Belgilash: burg'ulashdan oldin, birinchi navbatda chizilgan talablarni tushuning. Burg'ulashning asosiy talablariga muvofiq teshik liniyasining markaz chizig'ini belgilash uchun vositalardan foydalaning. Markaz chizig'i aniq va aniq bo'lishi kerak va ingichka yaxshidir. Chiziqni chizgandan so'ng, Vernier kaliper yoki po'lat hokimlik bilan o'lchang.
2. Draw an inspection square or inspection circle: After drawing the line and passing the inspection, an inspection square or inspection circle with the center line of the hole as the center of symmetry should be drawn as an inspection line during test drilling to facilitate inspection burg'ulash paytida. va burg'ulashning to'g'ri yo'nalishi.
3. Isbotlash va punch: tegishli tekshirish kvadratini yoki tekshiruv doirasini chizganingizdan so'ng, dalillarni sinchkovlik bilan bajarish kerak. First make a small point, and measure several times in different directions of the cross center line to see if the punch hole is indeed punched at the intersection of the cross center line, and then punch the sample in a straight, round, and wide direction aniq joylashtirish uchun. Pichoq markazda joylashgan.
4. qisqich: mashina stolini, armatura sirtini va ish qismini va ish qismini tozalash uchun lattadan foydalaning, so'ngra ish qismini qising. Qariyalash kerak bo'lgan darajada silliq va ishonchli bo'lishi kerak va istalgan vaqtda so'rov va o'lchash qulay. Ish qismining qisqichbaqasimon chiqarilishi tufayli deformatsiya qilinishi oldini olish uchun ish qismining qisqichbaqari usuliga e'tibor berish kerak.
5. Test drilling: Test drilling must be done before formal drilling: align the chisel edge of the drill bit with the center of the hole and drill a shallow pit, and then visually check whether the direction of the shallow pit is correct. Bundan tashqari, sayoz chuqurni va tekshirish doirasini Koaksiyal qilish uchun doimiy ravishda og'ishni tuzatish kerak. Agar og'ish kichik bo'lsa, asta-sekin tuzatishga erishish uchun burg'ulash paytida ishlov beriladigan qism og'ishning teskari yo'nalishiga surilishi mumkin.
6. Tartibga tortish: mashina burg'ulash odatda qo'lda ozuqa operatsiyasiga asoslangan. Sinovni burg'ulash holatini aniqlash kerak bo'lganda burg'ulash amalga oshirilishi mumkin. When manually feeding, the feeding force should not cause the drill bit to bend to prevent the hole axis from being skewed.
3. Yuqori burg'ulash aniqligi uchun usullar
1. Muroziy bitni keskinlashtirish hamma narsaning boshlanishidir
Tugallashdan oldin tegishli matkapli bitni keskinlashtirish uchun tanlanishi kerak. In addition to ensuring accurate vertex angle, clearance angle, and chisel edge bevel, the sharpened drill bit has the same length of the two main cutting edges and is symmetrical to the center line of the drill bit, and the two main flank surfaces are smooth, in order to facilitate centering and reduce the roughness of the hole wall. , the chisel edge and the main cutting edge should also be properly ground (it is best to rough grind on the grinder first, and then fine grind on the oilstone).

2. To'g'ri chiziq chizish asosidir
Belgilangan chiziqlarni belgilash uchun balandlik o'lchovidan foydalanganda, birinchi navbatda, siz tekislanishning aniqligini ta'minlashingiz kerak. Belgilash paytida, igna burchagi va ish qismining belgilari orasidagi burchak 40 dan 60 daraja (marka yo'nalishi bo'ylab). Shunday qilib, chiziqlar aniq va hatto. Scribing ma'lumotlar pog'onasini tanlashga e'tibor bering. Datumning samolyoti aniq va uning tekisligi va qo'shni yuzalarga perpenshityalityatsiya qilinishi kerak. Teshikli pozitsiyadan so'ng, burg'ulashni ta'minlash uchun kesishqoq chiziq chizilgandan so'ng, markaziy punktni kesib o'tish uchun markaziy punktni kesib o'tish uchun markaziy punktni kesib o'tish uchun (musht nuqtasi kichik bo'lishi kerak).
3. To'g'ri siqish asosiy hisoblanadi
Normally, for holes with a diameter less than 6 mm, if the accuracy is not high, you can use hand pliers to clamp the workpiece for drilling; Agar ish qismi muntazam va tekis bo'lsa, siz tekis burg'ulash mashinasiga perpendikulyar hosil qilish kerak. When drilling a hole with a larger diameter, the flat-nose pliers must be fixed with a bolt pressure plate; for larger workpieces with a drilling diameter of more than 10 mm, use the pressure plate clamping method to drill.
4. Kalitni aniq izlash kalit
Ish qismidan keyin burg'ulash uchun shoshilmang. Avval tekislash amalga oshirilishi kerak. Hizalash statik hizalanishni va dinamik jihatdan tekislashni o'z ichiga oladi. Statik hizalamalar burg'ulash mashinasi boshlanishidan oldin, burg'ulash mashinasining shpindlining markazi va ish qismining kesishishi markazi hizalanmasdan oldin tekislash uchun mos keladi. Ushbu usul yangi boshlanuvchilar uchun xavfsiz va qulaydir va mastore qilish osonroq. However, it does not take into account the swing of the drilling machine spindle, for example. Va boshqa noaniq omillar, burg'ulashning aniqligi past. Ducing talabalari boshlanganidan keyin dinamik tekislash amalga oshiriladi. Hizalani, ba'zi noaniq omillar hisobga olinadi va aniqligi nisbatan yuqori.
5. Ehtiyotkorlik bilan tekshirish zarur
The inspection can accurately and timely discover the accuracy of the hole so that necessary measures can be taken to compensate. For holes with high drilling accuracy, we generally use drilling, reaming, and reaming processing techniques. After drilling the small hole in the first step, use a caliper to detect the error offset from the center of the bottom hole to the datum. Haqiqiy o'lchovdan so'ng, pastki teshikka va ideal markazning pozitsiyasini hisoblang. Agar xato 0,10 mm dan yuqori bo'lmasa, siz teshikni kengaytirishingiz mumkin. Murakkab uchastkasini moslashtiring, avtomatik ravishda avtomatik ta'sirni susaytiradi, ish qismini ijobiy yo'nalishda to'g'ri suring va asta-sekin taqsimlash uchun burg'ulashning diametrini oshiring. Agar xato 0,10 mm dan yuqori bo'lsa, asirli teshikning yon devorlarini kesish uchun asrang fayldan foydalanish mumkin. To'rlangan qismi silliq o'tish davridagi pastki teshikning yoyi bilan bog'lanishi kerak.
