这些是CNC加工的机器人末端执行器——定制夹爪、真空歧管板和工具快换器——在我们的五轴DMG MORI铣床上从实心铝或钢坯料切割而成。您可获得±0.005 mm位置公差、0.01 mm同心跳动和48 HRC表面硬度(可选60 HRC),标准几何形状交货期为7天。无组装、无焊接、无隐藏变形——仅一块实心金属,将您的工件精确固定在机器人所认为的位置。

为什么机器人手腕需要比加工中心更刚性的接口

您的机器人手臂重复精度为±0.02 mm——但如果末端执行器在负载下弯曲0.03 mm,您将失去该精度。我们的CNC加工机器人末端执行器设计为2.5:1的刚度重量比,优于焊接结构。我们通过从单块7075-T6铝或4140预硬钢坯料加工实现这一点,消除了焊接变形和应力释放裂纹。接口板表面磨削至0.8 Ra,与机器人安装面齐平贴合——无需垫片,前100次循环后无需重新拧紧。

ER弹簧夹头如何无跳动夹持工具

大多数末端执行器单独螺栓固定夹头,这使公差累积加倍。我们直接将夹头座加工到执行器本体中——一次装夹,一个基准。ER20夹头座镗孔至H7公差(0/+0.012 mm),内锥面磨削至0.01 mm总跳动。当您夹持6 mm定位销或气动接头时,它精确居中。如果您需要非标准夹爪垫的定制孔径,我们可以将该孔保持在±0.005 mm,并仍在10天内发货。

我们为每种机器人负载使用的材料和热处理

根据工况匹配金属。对于10 kg以下负载,我们使用6061-T6铝——加工后硬质阳极氧化至60 HRC等效表面硬度,可抵抗塑料或碳纤维部件的磨粒磨损。对于高达50 kg的负载,我们改用7075-T6(屈服强度503 MPa)作为主体,夹持手指采用D2工具钢镶件,硬化至58–60 HRC。对于高温或腐蚀性环境(食品处理、焊接),我们加工17-4 PH不锈钢,时效至H900(40 HRC),然后进行钝化处理。每次热处理均在内部完成,并附有认证炉日志——无外包,无猜测。

每次发货前的检验:我们测量什么及其重要性

我们不会因为零件“看起来正确”就发货。每个CNC加工机器人末端执行器都经过蔡司三坐标测量机上的12点检验。我们测量:(1) 安装孔位置至±0.005 mm,(2) 基准平面度在100 mm范围内至0.005 mm,(3) 夹头跳动至0.01 mm TIR,(4) 夹持面表面粗糙度至0.8 Ra,(5) 本体三点硬度,(6) 螺纹深度使用通止规。检验报告随跟踪号通过电子邮件发送给您。如果任何尺寸超差,我们重新加工——不修补、不焊接、不照常发货。

对于复杂几何形状,我们还使用白光扫描仪(GOM ATOS)进行验证,并将网格与您的STEP文件进行比较。偏差图附在CMM报告中。这就是为什么我们的末端执行器无需手动返工即可直接投入生产线。这是中国精密制造,但附带您期望从德国或瑞士工厂获得的文档——成本低40%。

表面处理选项:从机加工态到镜面抛光(适用于粘性材料)

标准表面处理为所有功能面0.8 Ra,其余面3.2 Ra。但如果您要拾取粘合膜、橡胶垫圈或湿工件,我们可以将夹爪接触面抛光至0.2 Ra——这将摩擦系数降低15%,防止材料粘附在夹爪上。对于真空末端执行器,我们将密封面研磨至0.1 Ra,并增加0.5 mm O型圈槽,深度加工至±0.01 mm。如果您需要带纹理的抓握面以处理油性零件,我们可以通过EDM在夹爪面上加工交叉纹路图案(0.3 mm深)——即使在0.5 mm间隙下也不会打滑。

减重设计:如何在不损失刚性的情况下去除金属

从手腕上每移除100克,您的机器人就能运行快5%或承载多3%的负载。我们对本体进行拓扑优化——从您的STEP文件开始,在SolidWorks中运行FEA,并从低应力区域去除材料。典型结果:铝件减重25–30%,钢件减重20%。但我们从不留下无支撑的薄壁——最小壁厚为铝2.5 mm,钢1.5 mm,并通过仿真验证。如果您有特定的重量预算,我们满足它。如果没有,我们会告诉您哪些多余金属不起作用并将其切除。

螺纹孔布置:为什么我们直接在本体攻丝而非使用镶件

钢丝螺套增加成本并引入失效点。对于40 kg负载以下的CNC加工机器人末端执行器,我们直接在本体上攻丝——M3至M12,6H级。对于铝材,我们使用螺纹成型丝锥(而非切削丝锥),这会使材料加工硬化并防止高扭矩下脱扣。测试结果:7075-T6铝中的M6螺纹可承受12 N·m而不脱扣,比切削螺纹高20%。对于钢材,我们也使用滚压丝锥。如果您要安装重型传感器或频繁拆卸的气缸,我们会推荐螺纹镶件——但我们会说明原因,而非默认使用。

常见问题解答:为没时间阅读手册的工程师提供的快速解答

定制末端执行器的最小起订量是多少?

无起订量——我们以与批量生产相同的单价为您加工一件原型,因为我们的CNC装夹方式相同。

如果我的3D模型不是标准形状,你们能加工吗?

可以,发送任何STEP或IGES文件;我们将在4小时内审查几何形状的可制造性,并在需要时建议壁厚或公差调整。

你们如何保证表格中列出的尺寸?

每个单元均在蔡司CMM上测量并通过GOM扫描仪验证;检验报告随货附送,如果您发现差异,我们将报销您的检验费用。

如果我需要500件复杂执行器,典型交货期是多少?

原型7天,500件批量生产15天——我们24/7运行20台CNC机床,并会在您下单前与您分享生产计划。

在您指定下一个执行器之前,请阅读我们的CNC刀具选择指南——它解释了刀具几何形状如何影响曲面夹爪面的表面粗糙度。并查看我们的CNC加工公差指南,了解为什么±0.005 mm对您的零件尺寸是可行的及其成本。两者均免费,无需注册。

立即发送您的图纸。我们将在12小时内返回正式报价——附DFM报告(面向制造的设计),在您承诺前标记任何公差或材料问题。无起订量,无隐藏刀具成本,无意外。将您的STEP文件发送至sc@bquq.com,或通过WhatsApp联系我们:+86 13713157787。如果您时间紧迫,请在主题行中注明“effector”,我们将优先处理您的报价请求。
