Section 10.10 of completion on completion of each observation all monitoring equipment installed after laying, ofng conquipment installation, Embedment, and confirmed by the supervisor to check the quality before being allowed to begin monitoriuring instruments and equipment after completion of installation, Embedment, immediately to inspect and test the quality of et meascertificate information supervising people. 10.9.2 monitoring instruments installed inbuilt quality check each measuring poinof delivery, and should include monitoring equipment factory inspection and test reports and delivery acceptance, acceptance tance r procurement monitoring equipment shall be as provided in section 10.2 of the terms of this technology, inspection and accepd analyze ... 10.9.1 10.9 quality inspection and acceptance monitoring of equipment inspection and delivery inspection all ououlcontaining gross errors, should immediately test if determined when monitoring data contain a large systematic errors, you sh- 3 - (1) 能迅速而方便地装备新产品的投产,以缩短生产准备周期,降低生产成本; (2) 能装夹一组具有相似性特征的工件; (3) 能适用于精密加工的高精度机床夹具; (4) 能适用于各种现代化制造技术的新型机床夹具; (5) 采用以液压站等为动力源的高效夹紧装置,以进一步减轻劳动强度和提高劳动生产率; (6) 提高机床夹具的标准化程度。 3.2.2 现代机床夹具的发展方向 现代机床夹具的发展方向主要表现为标准化 精密化 高效化和柔性化等四个方面。 (1)标准化 机床夹具的标准化与通用化是相互联系的两个方面。目前我国已有夹具零件及部件的国家标准:GB/T2148,T2259,91以及各类通用夹具 组合夹具标准等。机床夹具的标准化,有利于夹具的商品化生产,有利于缩短生产准备周期,降低生产总成本。 (2)精密化 随着机械产品精度的日益提高,势必相应提高了对夹具的精度要求。精密化夹具的结构类型很多,例如用于精密分度的多齿盘,其分度精度可达?0.1";用于精密车削的高精度三爪自定心卡盘,其定心精度为5μm。 (3)高效化 高效化夹具主要用来减少工件加工的基本时间和辅助时间,以提高劳动生产率,减轻工人的劳动强度。常见的高效化夹具有自动化夹具 高速化夹具和具有夹紧力装置的夹具等。例如,在铣床上使用电动虎钳装夹工件,效率可提高5倍左右;在车床上使用高速三爪自定心卡盘,可保证卡爪在试验转速为9000r/min的条件下仍能牢固地夹紧工件,从而使切削速度大幅度提高。目前,除了在生产流水线 自动线配置相应的高效 自动化夹具外,在数控机床上,尤其在加工中心上出现了各种自动装夹工件的夹具以及自动更换夹具的装置,充分发挥了数控机床的效率。 (4)柔性化 机床夹具的柔性化与机床的柔性化相似,它是指机床夹具通过调整 组合等方式,以适应工艺可变因素的能力。工艺的可变因素主要有:工序特征 生产批量 工件的形状和尺寸等。具有柔性化特征的新型夹具种类主要有:组合夹具 通用可调夹具 成组夹具 模块化夹具 数控夹具等。为适应现代机械工业多品种 中小批量生产的需要,扩大夹具的柔性化程度,改变专用夹具的不可拆结构为可拆结构,发展可调夹具结构,将是当前夹具发展的主要方向。 o the supervisor to monitor the project's acceptance of special, and according to the technical provisions 16.1. thepply titoring equipment installed after laying, of 52nd of the references to this agreement the terms of the contract provisions, abefore being allowed to begin monitoring contract work.
