Abstract

An adjustment tool for adjustment operations on a machine has at least one mechanical adjustment member. The tool comprises a body, a tool head and a drive member. The tool head is mounted on the body and is adapted to be detachably coupled to the adjustment member. Further, the tool head is displaceable relative to the body. The drive member is configured for driving the tool head and the adjustment member coupled thereto. The adjustment tool further comprises a displacement limiter arranged to limit an amount of displacement which the drive member can impart on the tool head to a set value.

Claims

1. An adjustment tool for adjustment operations on a machine having at least one mechanical adjustment member, the tool comprising:

a body;

a tool head mounted on the body and adapted to be detachably coupled to the adjustment member, the tool head being displaceable relative to the body;

a drive member for driving the tool head and the adjustment member coupled thereto;

a set value defining unit for defining a set value indicating a predetermined amount of displacement for the tool head; and

a displacement limiter arranged to limit an amount of displacement which the drive member in operation imparts on the tool head to the set value.

2. The tool according to claim 1, wherein the drive member is arranged to rotate the tool head relative to the body.

3. The tool according to claim 1, wherein the drive member is a servo motor and the displacement limiter is constituted by an electronic servo controller.

4. The tool according to claim 1, wherein the drive member is a member that is arranged for being driven manually, and the displacement limiter is constituted by an encoder arranged for measuring the amount of displacement of the tool head relative to the body, an electric clutch arranged to selectively couple the drive member to the tool head, and an electronic controller for controlling the clutch on the basis of signals received from the encoder.

5. The tool according to claim 1, wherein the set value defining unit comprises a communication interface configured for wireless or wireline communication with a control system of the machine.

6. The tool according to claim 1, wherein the set value defining unit comprises a user interface configured for receiving the set value from a user.

7. The tool according to claim 1, comprising a display screen and a controller configured for displaying information related to the adjustment operation on the screen.

8. The tool according to claim 7, wherein the controller is arranged to display an image showing where the adjustment member to be adjusted is located on the machine.

9. The tool according to claim 1, wherein the set value defining unit comprises a tag reader arranged on the body for detecting and reading a tag on the machine.

10. The tool according to claim 9, wherein the tag reader and the controller are configured to derive set values for the amount of displacement by decoding information that is read by the tag reader.

11. The tool according to claim 1, wherein the body has a coupling member configured for being brought into engagement with a reference structure on the machine.

12. The tool according to claim 1, wherein the set value defining unit and the displacement limiter are purely mechanical, manually operated devices.

13. The tool according to claim 1, wherein the tool is configured to apply the amount of displacement in at least two opposite directions, the tool comprising two displacement limiters for limiting the amounts of displacement of the tool head in each of the at least two opposite directions.
