M440181 V. New Description: [New Technology Alliance] This creation involves a vibrating digital force wrench, especially an improved f-set with self-checking function, and the user can not only Visually check the current value of the f side, and generate sound and vibration when the torque value is used. It can transfer the torque to a receiving unit to facilitate the use and effective management on the production line. [Prior Art] Torque is the force that causes an object to rotate. In physics, it is the large value of the torque λ!, 'the product of the force and the force arm. The international unit is Nm (Newton·m) or other convertible torque unit. . In our normal life, sometimes a torque wrench is used to turn the nut or bolt to lock the object to achieve the purpose of locking. The force of this rotation is the moment. At the same time, there are many torsion tools available on the market that can be used to measure or display torque. For example: digital display torque wrench, mechanically adjustable sound-type torque wrench, and torque wrench combined with digital and mechanical sound design, + digit The torque wrench is provided with a digital die on the wrench body, and when the wrench body applies force to the object, the torque can be detected by the sensing component and the analog signal is amplified by the operation module. The torque value generated when tightening is detected by the gyroscope. When the torque wrench detects the set minimum torque value, the 3 rotation angle is started; therefore, '1 is displayed in the operation digits until the j The operator must continuously watch the value on the display screen and change the value of the torsion plate to stop the torque application. The digital measurement shows that the twist J is the sensitivity of the sister 117 when it is used by the built-in sensing component and the digital module. However, in practice, if you work, you must always look at the value on the display screen. Change, if the eye is "two =: = force on: the value of the old * on the screen, then the second: easy =] is also greatly discounted. 妁 digital torque tool practical ideas also have a spring-sounding type torque wrench is in The setting of the internal setting of the wrench! V# 'When the user uses the tension of the spring and the cam machine, the spring force reaches the vibration value of the w torque value, 'the cam will slide down to a groove to break the torque β = sound ° The user can use the touch or the sense of hearing to judge the wrench in the end of the (four) solid. Mechanical adjustment of the sound-type torque _; s need to be tested by the torque tester to set the Yao torsion and U (four) 1 for the majority of operators habitual _. The type (4) board has both digital precision and convenience, as well as the mechanical sounding of the work. At present, the twisted author who has combined the design of the digital sound machine can use the Wei-level module to measure the component to eliminate the same-torque force in the spring cam mechanism. Spring sheet The cam is spring acting in the same time reaches a preset torque M440181, since slipped to a strike recess and vibrate, while beep, the user can serve a tactile or audible to judge whether the arrival of the torsion lock is completed.

However, whether it is a digital display torque wrench, a mechanically adjustable sound-type torque wrench, and a torque wrench designed with a combination of digital and mechanical sound, before or during use, even after being affected by other external factors (such as falling ground) It is necessary to carry out the verification accuracy again; in the past, when testing the above various types of torque wrenches, it is necessary to use a special torque wrench tester for verification, and it must be slow when performing calibration. Turn the wrench to apply torque to observe whether the torque setting value is accurate and the calibration efficiency is also poor.
