Torque wrench adjustment tolerance indication


Indication of tolerance adjustment (Northeast Regional metering station machine manufacturer,[link widoczny dla zalogowanych], Shenyang City, Liaoning Province,[link widoczny dla zalogowanych], 110045) torque wrench is widely used in various enterprises. Its structure is not complicated, but because one of the great elastic spring, do not have the means to adjust said value, not only a waste of time, but also easy to pop-up parts hurt. General information or description of the factory and few notes to show the adjustment of the value of tolerance and handling methods. To this end, we will explore in practice out of the adjustment method introduced to everyone, for your reference. An indication of tolerance when not to rush to unload when the first open house. First moment of moving the ruler (ie, sleeve 5), see figure, adjusted to handle at one end to the limited length of the screwdriver to the screw 2 can access, but also make the smallest wrench in the spring in the elastic state, then, with a long screwdriver handle rod inserted in the back six holes to adjust the screw 2, the appropriate adjustment screw 2 to display the value of units cells. _ If the transfer does not move or transfer is not good, then to open internally removable adjustment. Figure Schematic diagram of the torque wrench shank unloading also need to adjust the torque to move the handle end of the rod 5, that the spring pressure to adjust to the smallest state, to prevent the pop-up parts hurt. Then adjust the screw with a screwdriver penetrated the six-hole 4 in the appropriate pressure,[link widoczny dla zalogowanych], remove the two fixed pins 7, 8,[link widoczny dla zalogowanych], and then unload the spring tabs, remove the sleeve 5, the torque adjustment screw rod 4 (which is L-screws) adjustment screw 2 to display the appropriate value of the units cell. Assembly of ridicule to which the spring is also playing the smallest state in the stretch for a smooth assembly. Received a 08-20 l99l dynamic assembly and information box car bursts through the identification of integrated test systems from the Nanjing University of Aeronautics & Astronautics Engineering, developed the test computer control, \The experts agreed that it reached a similar test system on the current international technical standards. The system is suitable for manufacturers of automotive electronics assembly production test plate and vehicle assembly plants and other departments of the product acceptance of objective, accurate and fast on the detection of Jie , is the assembly quality assurance and monitoring box a powerful tool. The system realizes the assembly box 6 of 58 41 electrical parameters of the automatic speed detection. The function is strong,[link widoczny dla zalogowanych], common good, the display prompts with the Chinese menu display intuitive, easy to operate, can be indicative of faulty or substandard electrical geometry, automatic quality statistics, histogram display, print records. appraisal committee of experts agreed that the novel structure of the system, advanced technology, the total of vehicle electrical into the test box is a national initiative for the domestic and imported cars electrical assembly box (central control) provides an effective means of quality assurance testing, has obvious social and economic benefits.
