Abstract

The invention provides a multifunctional calibrating and loading device for a torque multiplier and relates to the testing and calibrating techniques of the torque multiplier. The multifunctional calibrating and loading device is used for solving the problems that a torque loading device is small in measurement range and low in measurement accuracy, has few functions and cannot calibrate torque measurement devices of different structures in the background art. The calibrating and loading device comprises a pure torque loading subsystem, a lifting mechanism subsystem, a screw rod loading subsystem, a non-coaxial multiplier loading-mounting-regulating subsystem and a loading platform system. The multifunctional calibrating and loading device can utilize multiple torque loading manners including a coaxial torque loading manner, a non-coaxial torque loading manner, a double-moment arm torque loading manner or the like and is an important constituent part of a torque multiplier calibrating device; the loading position and manner of the loading device can be regulated according to the size and loading manner of the torque multiplier, and the torque loading problems caused when various torque devices of an assembling production line of an engine are calibrated can be solved by utilizing one set of loading device, so that the practicality of the multifunctional calibrating and loading device is greatly improved, and the cost is saved.

Description

technical field [0001] The invention relates to a calibration device for a torque multiplier, and relates to a testing and calibration technology for a torque multiplier. Background technique [0002] The torque parameter is an important parameter for the installation and debugging of the engine production line equipment, and also a very important parameter in the mechanical measurement. In the engine assembly, if the applied torque is too small, the assembly strength will not be achieved, resulting in loosening of the bolts; if the applied torque is too large , if it exceeds the range, it is easy to cause bolt tripping, torque failure, etc., which are absolutely not allowed in engine production and assembly. With the continuous increase of the company's new models, the assembly torque continues to increase, and the requirements for assembly technology continue to improve. The company introduced advanced torque measuring equipment and various special torque wrenches produce...
