Clamping tool with interchangeable arm
A clamping tool is provided comprising a body, containing control circuits and electronic processing circuitry and having, at one end, a handle for gripping by an operator making the clamping, and on the other end, an arm. The arm comprises, at its free end, a seat that can be alternatively pluggable to a plurality of inserts suitable for engaging the tool with a corresponding type and/or dimension of a mechanical member on which the tool is configured to operate to perform a clamping operation. Sensor means are provided on the arm for detecting tightening conditions exerted on the mechanical member. Furthermore, a microprocessor electronic card is provided on the arm for receiving analogic signals from the sensor means, converting the signals into digital format, and handling transfer of the signals in digital format to the electronic processing circuitry.
1. A clamping tool, comprising:
a body including control circuits and electronic processing circuitry, and having, at one end, a handle for gripping by an operator making a clamping, and on an other end, an arm, the arm comprising, at a free end, a seat that can be alternatively pluggable to a plurality of inserts configured to engage the clamping tool with a corresponding type and/or dimension of a mechanical member on which the clamping tool is configured to operate to perform a clamping operation,
a sensor provided in the arm and configured to detect tightening conditions exerted on the mechanical member, and
a microprocessor electronic card provided in the arm and configured to receive analog signals from the sensor, convert the analog signals into a digital format, and transfer the signals in the digital format to the electronic processing circuitry of the body,
wherein the arm is removably connected to the body through a connector allowing both a mechanical connection and transmission/reception of electrical and power supply signals between the arm and the body, and
the sensor and the microprocessor electronic card are inserted in a single support inside the arm.
2. The clamping tool according to claim 1 , wherein said microprocessor electronic card is further configured to perform filtering of the signals, and/or detection of torque peaks, and/or an elimination of spurious data, and/or an analysis of signal linearity.
3. The clamping tool according to claim 1 , wherein the microprocessor electronic card is powered by rechargeable batteries of the clamping tool.
4. The clamping tool according to claim 1 , wherein the microprocessor electronic card has rechargeable batteries.
5. The clamping tool of claim 1 , further comprising another sensor provided in the arm and configured to detect at least one of temperature and humidity;
wherein the microprocessor electronic card is configured to receive signals from the another sensor, convert the signals into the digital format, and transfer the converted signals to the electronic processing circuitry; and
the sensor, the another sensor, and the microprocessor electronic card are inserted in the single support inside the arm.
