Tightg. System (torque/pulses)

EC Impulse Tools Yokota YEX series impulse wrenches feature an integrated torque transducer (system wrenches). In combination with a controller YETC-210 the torque can be set, judged and stored thus enabling to document that the correct joint was made, in case of product liability claims. The system impulse wrenches only need 1 - 2 seconds for each joint. The tools have no kick-back and perfectly fit in a Poka Yoke assembly area. Applying reaction-free Yokota impulse wrenches at the assembly line reduces the RSI risk significantly. Key Features Equipped with the patented Yokota Twin Blade Impulse Mechanism. Integrated transducer enables full torque control. Four strain gauges are positioned on the mainshaft, picking up the twisting torque on the main shaft at each impulse as close as possible to the socket. The electric signals are transmitted by induction through the internal and external coils. Due to this principle the Yokota transducer is very reliable, accurate and...

EC Impulse Tools The YED system impulse wrenches are equal to the YEX series, but with the added feature of a double chamber air motor. The system impulse wrenches with double chamber air motor achieve the required torque very quickly. The tools generate a high number of impulses per second, therefore very accurate torques can be realized. Applying reaction-free Yokota impulse wrenches at the assembly line reduces the RSI risk significantly. Key Features Equipped with the patented Yokota Twin Blade Impulse Mechanism. Double chamber air motor for high-speed tightening. Integrated transducer enables full torque control. Four strain gauges are positioned on the mainshaft, picking up the twisting torque on the main shaft at each impulse as close as possible to the socket. The electric signals are transmitted by induction through the internal and external coils. Due to this principle the Yokota transducer is very reliable, accurate and without wear.

Electronical Torque & Pulse Controller The VDI Directive 2862 for the use of Tightening Systems in the Automobile Industry is classifying bolt joints into three precise categories. The directive also is a guideline for the selection and the use of suitable assembly tools or tightening systems. According to the directive security related bolt joints shall be counted, documented and of course be tightened with the proper preload force. To achieve this Yokota equipped the impulse wrenches with an integrated transducer. In combination with Yokota's electronical controller YETC-210 torque values can be controlled, monitored and, of course, recorded. The also monitored pulse number refers as a second parameter. An exact parameterization to individual joint characteristic (soft/hard) is feasible. Yokota's YETC controller measures, judges, counts and documents all tightened joints and if neccessary, files them in a computer. Communication between the controller and the computer...
