Abstract

A system, and a method of using a system, for controlled tool operation. The method includes providing a tool used in a force application such as a such torque application. The tool communicates with a controller which can communicate with the tool, and to a display in communication with the tool and the controller. The controller can be programmed with operational information about a tool operation. Information related to the operational information is displayed to a user during use. Service information including at least information about an amount of force applied during use is recorded and stored in the controller. Also disclosed is a computerized system for controlled tool operation which sends operational instructions to the tool before use and retrieves service information from the tool after use.

Claims

1. A method for controlled tool operation, the method comprising the steps of:

providing a hand-held tool including;

a lug nut driver operatively associated with the tool; and

a lug nut driver controller operatively associated with the tool, the controller being adapted for sensing a magnitude of torque applied by the tool and being adapted to alert the operator of a torque error;

providing a control unit having a first connection communicating with a cradle and a second connection communicating with a shop management system, the cradle being dimensioned for docking the tool to enable communication between the tool and the control unit, providing a shop management system being in detachable communication with the tool, the shop management system controllably generating work orders relating to lug nut driving operations;

providing a display operatively associated with the tool and the controller;

retrieving information for at least one work order on the shop management system;

transmitting at least one work order to the control unit for storage in the control unit;

selecting a work order stored on the control unit and transmitting the work order to the tool;

performing a lug nut torque application related to the work order using the tool;

recording service information including data corresponding to the actual torque applied;

transmitting the service information including the data corresponding to the actual torque applied to the control unit; and

transmitting the service information including the data corresponding to the actual torque applied from the control unit to the shop management system.

2. The method of claim 1, further comprising:

providing a first visual indicator corresponding to an approach condition;

providing a second visual indicator corresponding to a target applied torque condition;

providing a third visual indicator corresponding to an over-torque condition;

the first, second, and third indicators being coupled to the control unit; and

controllably operating the first, second, and third indicators to illuminate when a corresponding condition has been reached.

3. The method of claim 2, wherein the approach condition corresponds to from between 85% to 98% of the target applied torque.

4. The method of claim 2, wherein the over-torque condition corresponds to from 105% to 120% of the target applied torque.

5. The method of claim 2, further comprising:

providing an alert indicator coupled to the control unit;

producing a first alert on the alert indicator when the approach condition has been reached;

producing a second alert on the alert indicator when the target applied torque condition has been reached; and

producing a third alert on the alert indicator when the over-torque condition has been reached.

6. The method of claim 5, further comprising providing each of the first alert, second alert and third alert with a different alert indication.

7. The method of claim 1, wherein the work order includes operational information and job information.

8. The method of claim 7, wherein operational information includes at least a driver size, a target applied torque, a number of lug nuts per tire, and a lug nut service pattern for a selected vehicle.

9. The method of claim 7, further comprising the step of guiding the tool operation with the operational information.

10. The method of claim 7, further comprising:

controllably displaying a representation of a vehicle on the display;

displaying a tire position indicator corresponding to each of the at least one tire; and

activating the tire position indicator when an operation is to be performed on that tire.

11. The method of claim 10, further comprising providing a switch on the tool in communication with the control unit;

providing a tire position indicator;

cyclically rotating the tire position indicator between each of the tire position indicators upon actuation of the switch.

12. The method of claim 1, wherein the hand-held tool includes the display and the display includes an indicator for indicating an actual torque measurement over or under a target torque setting.

13. The method of claim 1, wherein the hand-held tool includes a sensory response alert indicator.
