2.3 Attachments installation procedures 附件安装

（1）Precautions for implementation of moving part 可动部分实装注意事项（图2-12）

1）The internal air hoses and cables are bent and twisted according to the operations of the J3 and J4 axes. Structurally，the twisting occurs inside the shaft，and the bending occurs inside the expanding sleeve. Without the expanding sleeve，the twisted air hoses and cables may run onto the guide portion of the fixing plate，and the air hoses may be bent or broken.

内装的气管、电缆根据J3轴、J4轴的动作进行弯曲和扭曲。结构设置为：在轴内部扭曲，在扩展套管部弯曲。不使用扩展套管时，在固定板的导向部分可能会发生扭曲的气管和电缆交错，从而导致气管折断或电缆断线。

2）Do not place the connector connecting part and the air hose relay part in the binding or twisting range.

请勿将插头连接部和气管的中继部设置在弯曲范围及扭曲范围内。

（2）Installation procedure 气管及电缆的内装方法

The installation procedure is shown in Fig. 2-13.

安装方法如图2-13。

1）Move the J3 axis to the top end with a jog operation and shut off the controller’ s power supply.

使用JOG操作使J3轴移动至上端，并切断控制器的电源。

2）Remove the screws fixing the No. 2 arm cover U，and remove the No. 2 arm cover U.

卸下固定2号机械臂盖板U的安装螺栓，卸下2号机械臂盖板U。

3）Pass the tool（hand）side of the internal air hoses and cables through the shaft. Make sure that the air hoses and the cables are not twisted or crossed.

使tool（抓手）的内装气管与电缆穿过轴内。确保气管、电缆无绞扭、交叉。

4）Fix the air hoses and the cables with a cable tie so as to position the end of the expanding sleeve 10mm away from the opening of the shaft.

使用扎带固定套管，使扩展套管上端在距离轴开口部约10mm位置。

5）The highest point of the curved section of the air hoses and cables should be matched up with the top of the fixing plate.

将气管和电缆的弯曲部顶点设为与固定板上端同一高度。

6）In the state of the steps 4）and 5），fix the air hoses and the cables to the“a”and“b”portions of the plate with cable ties.

在步骤4）、5）的状态下，将气管、电缆扎紧在固定板的“a”“b”部。

7）Installation of the hand input signal or the optional solenoid valve.

安装抓手输入信号或电磁阀组。

8）The connected connectors are stored to the“c”portion.

将连接器收至“c”部。

9）Carry out piping and wiring on the tool side.

安装tool侧的配管、配线。

10）Apply silicon grease to the contact surface between the air hoses of the fixing plate and the cables，the cable sliding portion from the shaft upper end to the fixed portion，and the opening on the shaft upper end.

在固定板的气管与电缆的接触面、轴上端部与固定部位之间的电缆转动部、轴上端部的开口处涂抹硅脂。

11）Power on the controller，perform the jog operation for the J3 and J4 axes，and check that the air hoses and the cables do not interfere with other components.

接通控制器的电源，使用JOG运行使J3轴、J4轴动作，以确认气管及电缆与其他零部件不发生干涉。

12）Turn off the controller’ s power supply，then install the No. 2 arm cover U securely as before with fixing screws.

切断控制器的电源后，用固定螺栓将2号机械臂盖板U按原样牢固安装。

（3）Installing the solenoid valve set 安装电磁阀组（图2-14）

（4）Installing the forearm external wiring set 安装前臂外部电缆组（图2-15）

（5）Installing the Base external wiring set 安装基座外部电缆组（图2-16）
