公制UNC/UNF和NPT管螺纹的螺纹尺寸、攻丝钻头、过孔和钻头
在您所需的螺纹百分比(默认75%)的理想孔附近的标准钻头,以及在另一系统中最接近的钻头。每个钻头都附带它实际提供的螺纹百分比,并且/tapdrill列出了从50%到90%的每个钻头,以供您选择
没有 主要 牙距 和 次要 直径 是根据基本的 螺纹 轮廓 公式 为每个 请求 计算的 所以 非标准 牙距 (M6x0.5) 也可以 使用 并 被 标记 为 标准:错误
还没有:尺寸是基本大小。标识中写的类别被接受并被忽略
最小标准孔位于或超过螺钉直径的2%(紧密)、6%(常规)或12%(松动),最小值较小。公制孔遵循标准的紧密、常规和松动系列
不 每个调用都在内存中计算 并且没有任何日志记录
是的,NPT锥形管螺纹尺寸从1/16到2英寸(获取/npt/{size}):的螺距直径、长度和螺纹高度根据锥形管螺纹公式计算。不包括干密封NPTF、直螺纹NPS和英制BSP螺纹。不适用于气体、压力或其他安全关键工作
管螺纹攻钻是车间实践,不属于标准,图表的尺寸差异为一号尺寸 API给出的是在手紧平面下小直径下的最大钻头(大多数图表显示的尺寸,1/2 NPT为23/32)以及在螺纹的细端(一号小,11/16,是在锥形铰刀之前的起始尺寸)
每个端点返回有关螺纹尺寸、攻丝钻头、间隙孔和钻头的详细信息。例如 GET /thread 端点提供大直径、螺距和小直径,而 GET /tapdrill 端点根据螺纹规格提供推荐的钻头尺寸
关键字段包括“名称”、“系统”、“公称直径”、“螺距”和“标准”。对于攻牙钻的响应,像“推荐”、“理想直径”和“线程百分比”这样的字段对于理解钻头尺寸建议至关重要
参数因终端不同而异 例如 GET /thread 接受 "designation" 来指定螺纹类型 而 GET /tapdrill 需要 "percentRequested" 来定义所需的螺纹嵌合百分比 用户还可以按 "system" 和 "series" 进行过滤
响应数据采用JSON格式结构化,以便清晰展示。例如“线程”对象包含“公称直径”和“螺距”等详细信息,而“攻钻”对象包含“推荐”钻头尺寸及其规格
每个端点提供特定信息:GET /thread 提供螺纹尺寸 GET /tapdrill 给出钻孔大小建议 GET /clearance 提供过孔尺寸 NPT 端点详细说明管螺纹尺寸和攻丝指南
用户可以通过指定参数来定制请求,例如线程的“指定名称”、钻头的“请求百分比”或NPT线程的“尺寸”。这允许根据特定需求或标准进行量身定制的响应
典型的用例包括为丝攻应用选择合适的钻孔尺寸 确定紧固件的间隙孔尺寸 以及参考管道螺纹规格用于管道工程 工程师和机械师经常使用这些数据
数据准确性通过基于既定线程轮廓公式的计算来保持 每个请求生成实时计算 确保尺寸反映当前标准和实践 而不是依赖静态图表
