The design of pin clamping device of automobile seat
Abstract: In the field of production automation, automated fixtures in recent decades to develop. Automation fixture is branched out from the industrial robot. Automation fixture features are expected to accomplish the various tasks of the job programmed, the merits of both humans and machines in construction and performance, especially high efficiency and adaptability embodies automation equipment. Automated fixture by the implementing agencies, the drive - drive mechanism, control systems, intelligent systems, remote diagnostic monitoring system of five parts. Drive - drive mechanism and implementing agencies are complementary, in the drive system can be pided into: mechanical, electrical, hydraulic and hybrid, in which the maximum operating force hydraulic, pneumatic lowest cost.
This topic is a car seat pin clamping device clamping the workpiece and parts and automatic operation of the device for its freedom of motion and more, and there are strict requirements for the operation sequence, operation can be achieved with a pneumatic drive automatic cycle, conducive to automation and high-efficiency requirements.
