Development Of Controllable Certain Torque Pre-loading Machine

As the great development of china's automobile industries, new and higher requirement is presented for the auto assembly automation domestical. Filter is an integral part of auto industry, its assembly reliability and automation affect the development of the entire automobile industry. The development of controllable certain torque pre-loading machine base on the series sizes of oil filter achieves the goal of filter semi-automated assembly. Contrasting various pre-loading methods, hydraulic system is applied to control torque, the relationship of hydraulic pressure and torque is measured through tests and more visual. The adjustments of vertical and horizontal for the series sizes filters and hydraulic system can achieve the pre-loading of controllable certain torque. PLC control system enhances the reliability and productivity of filter assembly greatly.The mechanisms of pre-loading machine not only fasten the oil filter, but also put flexible assembly for series sizes into practical effect. The hydraulic and pneumatic systems ensure the pre-loading operation. PLC control system sets 3 modes, automation, manual and exception handles, to enhance the reliability of semi-automated assembly. The development of controllable certain torque pre-loading machine effectively solves the domestical problem of oil filter semi-automated assembly.
