A torque checker is a device used to check the torque setting of an electric screwdriver. It is used to check if the tightening torque of the driver is set correctly, and is expected to prevent damage to the product caused by tightening with the wrong torque and deterioration of the product function due to insufficient torque.
Torque testers are mainly used in factories and other mass production sites.
Torque checkers are used to control the torque required to assemble products, since the appropriate torque is determined by the type of screw to be installed and other factors. If torque is not managed, there is a difference in tightening force between workers, which may lead to "damage due to over-tightening" or "deterioration of product functionality due to insufficient torque". On the other hand, by using a torque checker at the start of work and tightening to the correct set value, stable quality can be maintained regardless of the operator.
Checking the set value with torque checkers are usually not performed at every tightening operation, but only at the start of the day's work. Some products have instructions that the check should be performed after a predetermined number of assemblies have been completed in a day, so in this case, the check may be performed again at a predetermined number in accordance with the instructions.
Torque checkers generally consist of an adapter component called a fidaptor, which consists of a threaded shaft and spring, etc., and a measuring instrument that measures the torque and displays it digitally. With the fidaptor attached to the tip of the electric screwdriver, set it on the measuring instrument and drive the electric screwdriver to measure torque. The fidaptor has a set measurable range, and you need to use it properly depending on the torque value you want to set, so be careful.
The actual measurement of torque value is performed as follows:
Since there is a possibility of error in measurement, multiple measurements are often taken and the average value is used for torque management. Once the measurement has been made in the sequence ① to ③, if the measurement is made again, it is necessary to reverse the electric driver and remove the load on the fidaptor.
