How Pokayoke is ensured in Yokota System wrench

pokayoke yokota systemYOKOTA System Wrench is a tightening tool made in Japan and very popular in terms of high tightening speed and high accuracy. It works by air pressure, this force is what causes the system to work; in other words, it is the power that drives the machine. Air pressure is provided by an air compressor. This machine has a gas-powered pump mechanism that continually forces air into a steel container tank until the air becomes pressurized. By using this pressurized air tool works. 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. YOKOTA System Wrench is built-in having an error-proof function after tightening completed. Every tightening gives a feedback signal to the controller to ensure the tightening condition on the bolt. System Wrench Controller have angle monitoring function which is used to detect the movement of bolt-on tightening application and makes tightening accurate or Poka-Yoke.
Poka-yoke is a technique for avoiding simple human error in the workplace. Also known as mistake-proofing, goof-proofing, and fail-safe work methods, poka-yoke is simply a system designed to prevent inadvertent errors made by workers performing a process.
The function of the controller that ensured the Poka-Yoke is Torque limit, OK-NG-OKALL signal, Bolt count and Rundown Angle etc. Torque limit ensures the torque range of that particular application if the residual torque is not within the applied limit, the tool gives a signal to the controller and the controller indicates NG on the panel screen. Similarly, the Rundown angle is used to detect the error caused by the operator and condition of the tightening bolt on the application whether it tighten or loosen. Minimum angle value detects the double hit tightening, it means tightening over-tightening and Maximum angle value detect over-tightening or bolt free condition on the application.

Snug Torque - Yokota - Microntech Engineers

SNUG TORQUE - Yokota  In today’s blog topic the discussion will be about the snug point when the bolt is tightened and its significance in bolt tightening. Bolting joints are one of the most commonly used methods to join various parts together in  construction  and machines. They consist of bolts that hold and join other parts and are secured with the interlinking of the threads of bolt and nut.             There are two main types of bolted joint designs like in the tension joint, the joint should be designed such that the clamp load is never overcome by the external tension  forces  acting to separate the joint. If the external forces override the clamp load then the clamped joint will separate, allowing the free movement of the part which is not a part of bolting a joint. There are various torque control methods for tightening the bolts each method uses a different technique and control factors to achieve the proper tightening. These tightening methods are: - To

Microntech Yokota Grinder with durable Grinding wheel

  Microntech Yokota Grinder with durable Grinding wheel The pneumatic grinder can be defined as a powerful tool used for grinding or we can say abrasive cutting and polishing metal workpiece. The main function of the pneumatic grinder is to remove the excess metal from the surface to be ground or polished. Yokota pneumatic Grinder consists of a turbine-like rotor with vanes or blades mounted on it. The air hose from the compressor is connected to the grinder inlet and when the tool trigger is pressed the compressed air drives the motor. The air motor further drives a gear mechanism (Bevel Gear) to transmit the rotating power at a right angle to the output shaft on which the abrasive disk or grinder disk is mounted. The abrasive disk gets worn out after several uses and can be changed very easily. There are various kinds of discs which can be used on the grinder for different uses, such as cut-off disc, abrasive grinding disc, grinding stones and polishing pads. The grinding wheel us
