资料翻译译文 液压卡盘的设计方法 1.动机和目标 卡盘设计是连接设计与制造间的一项重要任务。自动化卡盘设计和计算机辅助卡盘设计开发（卡盘 CAD）是下一代制造系统成功实现目标的关键。在这片论文里，讨论了一种卡盘设计的方法，这种方法有利于在目前环境下卡盘设计的自动化。 卡盘设计方法的研究已成为国内多家科研工作的重点。作者：周在对工件的稳定和总需求约束了双重标准，突出重点的工作。在卡盘设计中广泛的运用了人工智能（ AI）以及专家系统。部分 CAD 模型几何信息也被用于卡盘设计。 Bidanda 描述了一个基于规则的专家 系统，以确定回转体零件的定位和夹紧。夹紧机制同时用于执行定位和夹紧功能。 DeVor分析了切削力钻井机械和建筑模型及其他金属切削加工。康有为在中定义了装配约束建模的模块化与卡盘元件之间的空间关系。一些研究人员采用模块化卡盘设计原则。另一些卡盘设计工作者已经做了报告，可以找到卡盘设计相关的大量的审查工作。 2.卡盘设计的整体方法 在本节中，描述了整体夹紧的设计方法。通常对较理想的位置的那一部分进行夹紧，并减低切削力的影响。夹紧的位置和卡盘设计中定位的位置是高度相关的。通常，夹紧和定位可以通过同样的方法来完成。但 是，不明白这两个是卡盘设计中不同的方面，可能导致卡盘设计的失败。多数人的在规划过程中首先解决定位问题，这样可以使开发的定位与设计的定位相契合。不过，整体定位及设计方法不在本文讨论范文内。 除了零件的设计（为此卡盘设计有待开发），公差规格，过程序列，定位点和设计等因素外，还应投入 CAD 模型到卡盘设计方法中。这样的卡盘可以夹紧并支撑定位器。指导使用的主要内容应尽量不抵制切割或加工过程和中所涉及的操作。相反，应定位卡盘，使切削力在正确的方向，这将有助于保持在一个特定的部分加工操作安全。通过引导对定位器的切割力量， 部分（或工件）被固定，固定定位点，因此不能移动的定位器。 在这里讨论的卡盘的设计方法必须在整体卡盘设计方法的范围内。在此之前进行定位器 /支撑和卡盘设计的初步阶段，涉及到的分析和识别的功能、相关的公差和其他规范是必要的。根据初步的评估和测定，定位 /支撑设计与卡盘设计结果的在此基础上可以同时进行。本文对所描述卡盘设计的方法讨论基于定位器 /支撑设计与先前已经确定的假设（包括适当的定位和支持测定一个工件的定位，以及识别和卡盘，如 V 元素的支持面块，基础板，定位销等）。 2.1 卡盘设计的输入 输入包括对特定产品的设计翼边模型，公差信息，提取的特征，过程顺序和部分在给定的每一个设计的相关特性的加工方向，面向的位置和定位装置，以及加工过程中的各种工序，须出示每个相应的功能。 2.2 卡盘设计的方法 具体步骤概述如下： 第 1 步：设置配置清单以及相关的 进程 _功能 条目。 第 2 步：确定方向和夹紧力。输入必要的加工方向向量 mdv1， mdv2 mdvn，面对nvs 的支持力，并确定法向量。如果加工方向向下（对应的方向向量 0， 0， -1），和面的支持向量平行于加工方向 ，那么，夹紧力方向平行向下加工方向 0， 0， -1。如果必需要侧面夹紧并没有可夹紧的地方，那么在其中放置一个卡盘夹紧下调，然后边钳方向计算如下。让 sv 和 tv 辅助常规的向量代替次要的和三级定位孔。然后，使用夹紧机构夹紧一个方向，例如， av 应平行于这两个法向量，即，正常向量应分别与每块表面的 sv 和 tv 向量平行。侧面夹紧面应该是一对分别平行于面 sv 和 tv 的平面孔。 第 3 步：从列表中选出最大有效加工力。这样能够有效的平衡各加工力。 第 4 步：利用计算出的最高有效加工力，才能确定用来支撑工件加工的面积的卡盘尺寸（例如， 一个带夹子可以作为一个夹紧机构使用）。 第 5 步：确定给定工件的夹紧面。这一步在第 4 步中所述过。 第 6 步：该卡盘的夹紧面的实际位置自动在第 5 步中确定。考虑接下来的步骤并返回第一步。 本文所讨论的方法的独特性是零件的夹紧面的几何形状，拓扑和功能发生了被加工为基础的系统鉴定。其他方法都没有利用了定位器的位置，该方法使用定位器在对持有一级，二级和三级定位器加工的工件。这种方法的另一个好处是在可行的候选面上确定在面上用卡盘面交点测试（如前所述），并迅速和有效地确定潜在的下游过程中可能出现问题，夹紧和加工的功能检测。 3.总结 在这篇论文中，对在一个卡盘设计方法的总体框架内进行了卡盘设计方面的讨论。 设计定位器，规范零件设计，和其他相关被用来确定夹紧面和夹紧方向。并讨论了各种自动化步骤。 液压卡盘的主要设计计算 ， 概括起来 ，就 是确定最大载荷 ， 根据最大载荷确定夹紧力 ，根据夹紧力 ， 计算碟形弹簧的轴向推力 ， 并按此轴向推力设计碟形弹簧。碟形弹簧的设计是液压卡盘的设计关键 ,在设计和制造上都不能出现问题 ， 否则液压卡盘不可靠 。 该碟形弹簧式液压卡盘零件较少，结构紧凑、简单，更换卡瓦和其他易损件比较方便。与油缸式卡盘结构相比，液压系统比较简 单，使用的油管少，工作性能稳定可靠。 外文原文 Design method of hydraulic chuck - An automated design method of the chuck J. Cecil 1.Motivation and goal Chuck design is an important link between design and manufacturing tasks. Automation design and computer aided chuck chuck chuck (CAD) design development is the key to the next generation of manufacturing system to achieve the target. Discussed in this paper, a method of chuck design, this method is beneficial to chuck in the current environment design automation. Chuck design method research has become the focus of the domestic many scientific research work. Author: weeks on the stability of the artifacts and aggregate demand constraint the double standard, focused work. The chuck widely applied in the design of artificial intelligence (AI) and expert system. Part of the CAD model geometry information has also been used in the design of chuck. Bidanda describes a rule-based expert system, to determine the positioning and clamping of axially symmetrical parts. The clamping mechanism is used to perform the positioning and clamping function at the same time. DeVor drilling machinery and construction analysis of the cutting force model and other metal cutting processing. Kang youwei assembly constraints defined in the modeling of modularization and spatial relationship between chuck components. Some researchers used modular chuck design principles. Other chuck design workers have done a report, you can find the chuck design review related to a lot of work. 2.Chuck design of integral method In this section, describes the whole design method of clamping. Usually for that part of the ideal location for clamping, and reduce the influence of cutting force. The position of the clamping and chuck positioning is highly related to the location of the design. Usually, clamping and positioning can be finished by the same method. But, dont understand this is two different aspects in the design of chuck, may lead to the failure of the chuck is designed. Most people in the process of planning the first solve the problem of positioning, so that we can make development positioning and design of positioning. However, the overall positioning and design method is not discussed in this article the idol. In addition to the components of the design (design) should be developed for this chuck, tolerance specifications, process sequence, anchor point and design factors, such as should also be put into CAD model to chuck design method. The chuck can be clamped and supported locator. The main content of the guide to use should try not to boycott the cutting or machining process and involved in the operation. On the contrary, should locate chuck, make cutting force in the right direction, this will help keep safe operation in a specific part of the processing. Cutting force through the guide to the locator, part of (or workpieces) are fixed, fixed anchor point, so cant move the locator. The chuck here to discuss the design method must be within the scope of the overall design method of chuck. Before this locator/support and initial stage of the chuck design involves the analysis and recognition function, related tolerance and other specifications are necessary. According to preliminary assessment and measurement, design and chuck positioning/support design on the basis of the result can be simultaneously. Chuck described in this paper, the design method is discussed based on the locator/support design with previously established assumptions (including the appropriate location and support of a workpiece positioning, as well as identify and chuck, such as V elements support surface of the block, base plate, pins, etc.). 2.1 chuck design input Input including wing side model, the design of a specific product tolerance information, extract the features, process sequence and some related characteristics of each design in a given processing direction, geared to the needs of the location and positioning device, various working procedure, and the process required to present each of the corresponding function. 2.2 chuck design method Specific steps outlined below: Step 1: set up the configuration list and related process _ function entry. Step 2: determine the orientation and clamping force. Input the necessary processing direction vector mdv1 mdv2. MDVN, face upward force NVS, and normal vector were determined. If processing direction downward (corresponding to the direction of the vector 0, 0, 1), and the support vector parallel to the direction of processing, so, clamping force direction parallel processing downward direction 0, 0, 1. If necessary to side clamp is not capable of clamping, then place a chuck clamping down on them, then side clamp direction calculation as follows. Let sv and TV auxiliary conventional vector instead of the secondary and tertiary locating holes. Then, use the clamping mechanism of clamping a direction, for example, av should be parallel to the two normal vector, i.e., the normal vector should be parallel to each sv and TV on the surface of the vector. Side clamping surface should be a pair of parallel to the plane of sv and flat faces of the TV. Step 3: select the maximum effective processing from the list. It can effectively balance the processing power. Step 4: use to calculate the maximum effective processing, can be used to support the area of the workpiece processing chuck size (for example, a belt clip can be used as a fastening device). Step 5: to determine if a given workpiece clamping surface. This step is described in step 4. Step 6: the chuck clamping the actual location automatically determined in step 5. Consider the following steps and returns the first step. Is discussed in this paper, the method of the uniqueness of parts clamping surface geometry, topology and feature the processed on the basis of system identification. Other methods are not using the locator, the method USES the locator to hold level, secondary and tertiary positioner of the workpieces. Another benefit of this approach is determined on the viable candidate in surface intersection test card disk (as mentioned above), and quickly and effectively identify potential problems may occur during the process of downstream, clamping and processing function of detection. 3. Summary In this paper, on the design method of a chuck chuck design within the overall
