Abstract

A holding tool for use in holding a first portion of an item, such as a hydraulic coupling, in a static position, while a torque application tool applies torque and rotates a second portion of the item. The holding tool helps reduce twisting of the first portion relative to the second portion when torque is applied. The holding tool also communicates with a controller when the tool is in use. For example, the tool communicates with the controller in response to a user applying a force to the tool in a direction of the first portion the tool is engaged with. That force releases pressure on a switch that activates a communication signal for communication to the controller. This allows the controller to monitor whether the holding tool was used in conjunction with a torque wrench to tighten the coupling; thereby providing an error reducing function.

First claim

What is claimed is:

1. A holding tool comprising:
a housing having first and second ends;
a handle coupled to the second end;
a head extending from the first end;
a transducer beam disposed in the housing and coupled to the head, the transducer beam including an aperture adapted to allow movement between the transducer beam and the housing;
a torque block disposed in the housing and coupled to the transducer beam;
a spring disposed in the housing and around the torque block; and
an interface module coupled to the housing between the first and second ends, wherein the interface module includes a switch adapted to actuate between ON and OFF positions, and wherein a force applied, by a user, to the handle in a direction towards the head causes movement of the handle and housing with respect to the transducer beam and the torque block and against a bias force of the spring, and wherein the movement causes the switch to actuate from the OFF position to the ON position and causes transmission of a signal including an indication that the switch is in the ON position.

2. The holding tool of claim 1 , wherein the interface module includes an indicator adapted to activate when the switch is in the ON position.

3. The holding tool of claim 1 , wherein the aperture extends through the transducer beam and is adapted to receive a pin to couple the transducer beam to the housing.
