KUKA KR 5-2 arc HW
|Produktbezeichnung||KR 5-2 arc HW|
The KR 5-2 is an industrial robot with a hollow shaft whist in axes 5 and 6. It is usually used for welding and applying adhesive and sealing.
Hollow-shaft wrist The robot is fitted with a 2-axis hollow-shaft wrist. The hollow-shaft wrist contains axes 5 and 6. The motors of axes 5 and 6 are incorporated in this assembly. The axes are driven via toothed belts and gear units. The design enables the fluid supply to be routed directly through the center of axis 6 to the application. For attaching end effectors (tools), the in-line wrist has a mounting flange.
Arm The arm is the link between the hollow-shaft wrist and the link arm. It houses the motors of the wrist axes A 3 and A 4. The arm is driven by the motor of axis 3. The maximum permissible swivel angle is mechanically limited by a stop for each direction, plus and minus. The associated buffers are attached to the link arm. The entire drive unit of axis 4 is also integrated inside the arm. In addition, the cable harness for the wrist axes A 5 and A 6 is installed under a cover. Fastening facilities are provided for the welding application equipment on the rear of the arm. The fluid supply to the tool is routed axially through the arm.
Link arm The link arm is the assembly located between the arm and the rotating column. It consists of the link arm body and the buffers.
Rotating column The rotating column houses the motors of axes 1 and 2. The rotational motion of axis 1 is performed by the rotating column. This is screwed to the base frame via the gear unit of axis 1 and is driven by a motor in the rotating column. The link arm is also mounted in the rotating column.
Base Frame The base frame is the base of the robot. It is screwed to the mounting base. The flexible tube for the electrical installations is fastened to the base frame. Also located on the base frame is the control cable junction box.
Electrical installations The electrical installations include all the motor and control cables for the motors of axes 1 to 6. All connections are implemented as connectors in order to enable the motors to be exchanged quickly and reliably. The electrical installations also include the RDC box and the motor terminal box, both of which are mounted on the robot base frame. The connecting cables from the robot controller are connected to these junction boxes by means of connectors. The electrical installations also include a protective circuit. For the supply to the wrist axis drives, an additional cable harness is integrated into the arm, which ensures that the cables are guided without kinking throughout the motion range of axis 4.
