A torque checker is a device used to verify the torque setting of an electric screwdriver. It is used to ensure that the tightening torque of the driver is set correctly, preventing product damage due to incorrect torque and product function deterioration due to insufficient torque.
Torque testers are primarily used in factories and other mass production sites.
Torque checkers are used to control the torque required for product assembly, as the appropriate torque varies based on the screw type and other factors. Failure to manage torque can lead to variations in tightening force among workers, potentially resulting in "damage due to over-tightening" or "product function deterioration due to insufficient torque." Conversely, by using a torque checker at the beginning of work and tightening to the correct set value, stable quality can be maintained, regardless of the operator.
Typically, checking the set value with torque checkers is not performed with every tightening operation but only at the start of the day's work. Some products have instructions specifying that the check should be performed after a predetermined number of assemblies in a day. In such cases, the check should be repeated according to the provided instructions.
Torque checkers generally consist of an adapter component called a "factor," which includes a threaded shaft a spring, and a measuring instrument that digitally displays the torque. To measure torque, attach the adaptor to the tip of the electric screwdriver and set it on the measuring instrument. The adaptor has a specified measurable range, so it must be used correctly depending on the desired torque value.
The actual torque value measurement process is as follows:
Since there is a possibility of measurement error, multiple measurements are often taken, and the average value is used for torque management. After completing measurements in steps ① to ③, if additional measurements are needed, the electric driver must be reversed, and the load on the adapter must be removed.
