描述
Estic TNA1-TU01-SH本身并非PLC（可编程逻辑控制器），而是Estic公司推出的交流伺服螺母拧紧工具单元。Estic以其在工业装配领域提供精密紧固解决方案而闻名。
它是自动化紧固系统中的关键组件，旨在与Estic控制器（例如ENRZ-MU50主控单元或类似产品）配合使用，并可能与PLC集成以实现整体生产线控制。
以下是其主要功能和用途的细分：
Estic TNA1-TU01-SH交流伺服螺母拧紧工具单元
主要功能
TNA1-TU01-SH是伺服螺母拧紧系统的“工具”部分。它能够以高精度、高速度和高准确度执行螺栓或螺母的实际紧固（拧紧），使其成为汽车、电子和航空航天等行业关键装配操作的理想选择。
主要特点
交流伺服电机：该装置采用交流伺服电机，可在拧紧过程中精确控制扭矩和角度。这支持多种拧紧策略，包括：
扭矩控制：拧紧至指定扭矩值。
角度控制：达到特定扭矩后，以特定角度拧紧。
扭矩监控：监控整个拧紧过程中施加的扭矩。
屈服点控制：拧紧至材料的屈服点。
高精度和准确度：Estic以其高精度而闻名。该装置可能配备应变式扭矩传感器（通常配备8个应变片，以提高精度和消除噪音）和用于精确角度反馈的旋转变压器。这可实现高精度拧紧，通常动态精度可达3σ/X≦2%（满量程）。
耐用设计：专为工业环境设计，通常配备耐用的减速器和坚固的结构，以确保在连续运行下具有长寿命和稳定的性能。
紧凑外形：设计紧凑，内置齿轮组，有效降低高度，适用于空间受限的应用。
扭矩范围广：Estic工具单元通常涵盖广泛的扭矩范围（例如，从0.5 Nm到3000 Nm，但特定型号TNA1-TU01-SH的扭矩范围会更窄，更具体）。
监控功能：除了控制之外，它还可能包括扭矩速率监控和区域监控等监控功能，以检测拧紧过程中的异常情况，确保质量并防止缺陷。
系统集成
TNA1-TU01-SH单元不能独立运行。它是一个大型系统的一部分，通常包含：
Estic控制器（例如，ENRZ-MU50主控制单元或ENRZ-AU50M轴控制单元）：它是编程和控制拧紧顺序、管理参数以及与外部系统通信的“大脑”。
TNA1-TU01-SH工具单元：实际的拧紧机构。
HMI/软件：用于设置程序、查看结果和诊断。
PLC（可编程逻辑控制器）：这就是“PLC”的用武之地。Estic控制器（例如ENRZ-MU50）可以通过串行通信（例如RS-232C、RS-422）、以太网或现场总线与中央PLC通信。然后，PLC管理整个装配线、排序操作，并从Estic控制器接收拧紧结果和错误状态。
The Estic TNA1-TU01-SH is not a PLC(Programmable Logic Controller)itself.Instead,it’s an AC Servo Nutrunner Tool Unit from Estic,a company renowned for its precision tightening solutions in industrial assembly.
It’s a crucial component in an automated fastening system,designed to work in conjunction with an Estic controller(like an ENRZ-MU50 Master Control Unit or similar)and potentially integrated with a PLC for overall line control.
Here’s a breakdown of its likely features and purpose:
Estic TNA1-TU01-SH AC Servo Nutrunner Tool Unit
Primary Function
The TNA1-TU01-SH is the”tool”part of a servo nutrunner system.It performs the actual fastening(tightening)of bolts or nuts with high precision,speed,and accuracy,making it ideal for critical assembly operations in industries such as automotive,electronics,and aerospace.
Key Features
AC Servo Motor:It incorporates an AC servo motor that provides precise control over torque and angle during the tightening process.This allows for various tightening strategies,including:
Torque Control:Tightening to a specified torque value.
Angle Control:Tightening a specific angle after reaching a certain torque.
Torque Monitoring:Monitoring the torque applied throughout the fastening process.
Yield Control:Tightening to the material’s yield point.
High Precision and Accuracy:Estic is known for its high accuracy.This unit likely features a strain gauge type torque transducer(often with 8 strain gauges for better accuracy and noise cancellation)and a resolver for precise angle feedback.This enables highly accurate fastening,often with a 3σ/X≦2%(at Full Scale)dynamic accuracy.
Durable Design:Built for industrial environments,it usually features a durable reducer gear and robust construction to ensure longevity and stable performance under continuous operation.
Compact Form Factor:Designed to be compact,especially with built-in gear trains to reduce height for applications with space limitations.
Wide Torque Range:Estic tool units often cover a wide torque range(e.g.,from 0.5 Nm up to 3000 Nm,though the specific TNA1-TU01-SH model’s range would be narrower and more specific).
Monitoring Functions:Beyond just control,it likely includes monitoring functions like Torque Rate monitoring and Zone monitoring to detect abnormalities during the tightening process,ensuring quality and preventing defects.
Integration within a System
The TNA1-TU01-SH unit doesn’t operate independently.It’s part of a larger system typically comprising:
Estic Controller(e.g.,ENRZ-MU50 Master Control Unit or ENRZ-AU50M Axis Control Unit):This is the brain that programs and controls the tightening sequence,manages parameters,and communicates with external systems.
The TNA1-TU01-SH Tool Unit:The actual tightening mechanism.
HMI/Software:For setting up programs,viewing results,and diagnostics.
PLC(Programmable Logic Controller):This is where the”PLC”aspect comes in.The Estic controller(like the ENRZ-MU50)can communicate with a central PLC via serial communication(e.g.,RS-232C,RS-422),Ethernet,or Fieldbus.The PLC then manages the overall assembly line,sequencing operations,and receiving tightening results and error statuses from the Estic controller.
