22160 - Grippers for HIGH and LOW type motors

The device is designed to enable the operator to safely move the HIGH and LOW reference points.

Intended use of the device

As part of the project, two grippers were manufactured—one each for the HIGH and LOW engine types—and the manipulator arm was modified to work with these devices.

The grippers are operated manually. The motor is gripped by closing the plastic jaws (by turning the lever on the upper beam). The devices allow the workpiece to be picked up in three different positions, as well as changing its orientation in mid-air. The angular position, within a range of -90 to 90 degrees, is adjusted using a lever on the right arm.

Grippers for HIGH and LOW reference types feature a similar design and operating principles. The differences lie in the arm lengths, the axis of rotation and the shape of the clamping jaws.

Description of operation

To close the jaws:

• lift the locking pin located beneath the locking handle;
• rotate the lever 180° anti-clockwise;
• insert the pin into the socket. The holes in the plates on the lever should align with the symbols below them (the entire indicator window should be filled with green).

To release the jaws:

• lift the locking pin located beneath the locking handle;
• in addition, lift the pin in the ‘Unwanted Jaw Opening Lock’;
• rotate the lever through 180°, clockwise;
• insert the pin into the socket. Also insert the jaw opening lock pin.

To change the orientation of the gripper jaws:

• squeeze the lever (lift the locking pin);
• select one of the three positions: -90°, 0°, 90°;
• release the lever. Ensure that the locking pin has engaged in the socket.

Device construction

TRANSPORT EYE

The transport eye, bolted to the upper beam of the gripper, enables quick changeover on the manipulator arm, as well as easy transport within the plant.

CLAMP CLOSING/OPENING LOCK

The jaw opening/closing lock, in the form of a locking pin, is designed to prevent uncontrolled opening or closing of the gripper during operation. The pin automatically engages in the socket when the jaws are fully open or closed.

GRIPPER ORIENTATION LOCK

The gripper orientation lock, in the form of a locking pin, is designed to prevent uncontrolled rotation of the motor in the air once it has been picked up. The pin automatically engages into the socket when the motor is in one of three possible positions: -90°, 0° or 90°. It is released by pressing the lever on the handle.

GRIPPING JAWS

The gripping jaws are the components that come into direct contact with the motor. Their surface precisely matches the shape of the workpiece being picked up and ensures a secure, safe grip. They are made of plastic to prevent damage to the motor body.

Benefits for the customer/user

• Streamlining the process of moving HIGH and LOW motors;
• The ability to pick up and set down motors in three different positions. The orientation can be changed whilst in the air;
• Ergonomic design for the operator.
