【導讀】依據(jù)車體焊裝線夾具設(shè)計理論，對各工位焊接夾具及其焊裝總線進行規(guī)劃、設(shè)計，焊裝夾具，是焊接工藝的重要組成部分。裝配和焊接夾具除了是完成這個過程中零。和焊接質(zhì)量的任務(wù)。汽車焊裝夾具是保證其制造質(zhì)量、縮短其制造周期的重要手段。所必須解決的問題。共同的,可以借鑒采用。焊接夾具的結(jié)構(gòu)設(shè)計,確保該夾具有良好的操作方便性、裝夾定位的可靠性。整，以確保立體可調(diào)。夾具設(shè)計通常是夾具上全部元件的位置都是直接根據(jù)設(shè)計基準確定的，最終。根據(jù)作業(yè)高度可初步?jīng)Q定夾具底板的高度，即夾具固。部分手動夾緊產(chǎn)品已擁有標準的。型號和數(shù)量，需要時可以到市場購買即可。置的焊接條件應(yīng)符合設(shè)計尺寸的工件坐標系定位夾具,這牽涉到的基準。工,但同時使用的測量與基準精確?？紤]采用可以活動的定位銷。為了方便工件進出,可選用伸縮定位銷，具體的結(jié)構(gòu)可查找。成的平面內(nèi)，以免夾緊力使工件彎曲或脫離定位基準。計和制造出高質(zhì)量焊接夾具系統(tǒng)是一項極其復雜的工程。
【正文】 Xi point was not necessarily suited fixture bearing surface with NC, which requires supporting the fixture block access point S as the base, the establishment of a digital surface, this surface should be consistent and be the Bearing surface, so that when it was manufactured to S base point for NC machining, precision machining and assembly debugging easy. 4. positioning the workpiece The general location of the workpieces to holes or obvious surface features as the positioning reference surface. The positioning pins are monly used ponents. Fixture positioning subactivities, and fixed positioning of two, for some jobs, in order to facilitate the workpiece into and out, positioning the form of optional activities, events or block pin positioning structure of the form subpneumatic and manual, in principle, put the workpiece seeded, positioning pieces to open into the workpiece, the positioning pieces out, and then clamp。 workpiece removed, the position to return items before and after clamp release. Activities can be used locate pieces of the movement structure of pantype or flipstyle, pantype structure is usually given priority. 5 welding pieces of the station transfer between Most auto welding parts to be welded in several station, so it needs transmission device, usually to avoid interference welding fixture, the workpiece in the transmission before the first piece rises, which requires use elevator, lifting bodies Gear rack, fourlink, etc., rack and pinion drive 8 structure processing and link structure are not as good. usually link structure Station transmission between the institutions, there are several forms, ie gear and rack transmission anizations, nonrod cylinders, transmission anizations, rocker transfer institutions, because form is the reciprocating motion, rocker transfer agencies are from manufacturing to missioning better than the others, so mon rocker transfer agencies. 6 Conclusion Automotive Welding Fixture many concrete structure, this is only in recent years, some of them work experience, along with the development of Chinese automobile industry on the requirements of more and more welding fixture, welding fixtures principle is simple, but real design and manufacture highquality welding fixture system is a plicated project, I hope, serve this article
