Abstract

The invention discloses a twisting and measuring machine for a main cone nut of a drive axle assembly. The twisting and measuring machine comprises a main cone nut twisting mechanism, a gyroscopic moment measuring mechanism and a rotation stopping mechanism. The main cone nut twisting mechanism comprises a sliding table drive air cylinder, a sliding table, a twisting shaft and a common shaft, all of which are sequentially connected from top to bottom. The main cone nut is sleeved with the bottom of the common shaft. The gyroscopic moment measuring mechanism comprises a servo motor, a clutch, a torque sensor, a transmission bearing, a first synchronous pulley and a second synchronous pulley, all of which are sequentially connected from top to bottom. The first synchronous pulley is connected to the bottom end of the transmission bearing, and the second synchronous pulley is connected to the top end of the common shaft and is in transmission connection with the first synchronous pulley. The rotation stopping mechanism comprises an ascent and descent lifting air cylinder and a rotation stopping part connected to the ascent and descent lifting air cylinder. The rotation stopping part is used for being connected with a main reducer flange. The twisting shaft is used for twisting the main cone nut, the torque sensor is used for directly measuring the gyroscopic moment of a main cone, and the two mechanisms share one common shaft; and the measuring accuracy of the gyroscopic moment of the main cone is improved, and cost is reduced.

Description

technical field [0001] The invention relates to the field of main reducers, in particular to a driving axle assembly main cone nut twisting and testing machine. Background technique [0002] In the field of processing and assembly of drive axle assembly, after the main cone nut is tightened, the rotation torque of the main cone will be measured to see if it meets the process requirements. The traditional measurement of the rotation torque of the main cone nut is to indirectly measure the free rotation torque of the main cone with a pressure sensor. , due to a conversion process and a complicated force arm conversion process, it has a certain influence on the measurement result of the main cone rotational moment, and it is prone to inaccurate measurement in practical applications. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a driving axle assembly main cone nut twisting machine to solve the problem of inaccura...
