PokaYoke Impulse Tool with Controlled Shut-Off
The Yokota YJ series impulse wrenches with double chamber air motor achieve the required torque very quickly. These tools generate a higher number of impulses per second, and therefore very accurate torques can be realised, resulting in increased production speed.
Yokota impulse wrenches are widely used for tightening jobs in the assembly industry, where accurate torque tolerances are necessary. Impulse tools are light, powerful, small and very importantly, have no kick-back. Evaluation of tightening processes in car assembly shows that tightening joints uses 10% of the total assembly time. Working with faster tools therefore can speed up assembly lines substantially.
In combination with the Poka Yoke controller YTC-3 predefined monitoring parameters will effect an optimized clamping force by electronically controlled shut-off. Applying reaction-free Yokota impulse wrenches at the assembly line will also reduce the RSI risk significantly.
