The Research Of The Assembly System Of The Shock Absorber Screwing Machine

Shock Absorber is a damping device, actually, which is the most significant energy dissipation of the suspension. It's responsible for the provision of low-quality spring set acceleration and the control of non-spring quality contained in the suspension. The shock absorbers is installed in parallel with the elastic components, in order that shock attenuation can be achieved to improve the car ride.With the rapid development of the automobile industry, as important parts of the car's accessories, shock absorber are steady growth in market demand, It is very necessary to increase productivity, increase production, by changing its original production.The assembly system of the shock absorber screwing machine is combine of the last link in the production line of SACHS, the pillar of the assembly for assembly, through the establishment of electromechanical integration equipment and change the original assembly ways to the automatic one, in order to achieve accurate, effective, simple multi-objective control Methods used in the production.This article first Analyze the assembly, Take the post-C24 for example: nuts, gaskets, rubber block, casing, rubber bushings, compression block limit, the guard, link board, assembly together, and so on, that is, in the end , the use of the head of a self-locking nut through a suitable static torque of its combination of torque lock, which is the main point. And the link between the nut and the pillars for the united thread, is the screw thread link, so really the final assembly is connected to the discussion thread.After that, with the combination of the mechanical theory of thread, The article discuss all the ways existing nowadays, the torque,angle-torque,yield point methods, combined with electrical and sensor technology, choose the suitable assembly method of control– torque/angle. The testing system controls the electromotor with the core of industrial control computer to realize the completely automatic testing depended on high precision force sensor, signal processing circuit, and PCL-818L data acquisition card of ISA bus.This article Introduced details of the hardware devices, from two parts-the mechanical and electrical, including the selection of solution, sensors and motors to choose from, connecting hardware, data acquisition and conditioning system. PC software for the erection of the structure and human-computer interaction design, and the usage of the multimedia timer to achieve precise control of sampling, as well as data filtering software, also launched an in-depth discussion.Finally, following the practice of deep analysis of the test, through the adjustment of process and parameters, the results is under the comparison which in order to made up for a special assembly in the shock absorber assembly of the pillars, in conjunction with testing done by the system and the existence of the defect and improve the ways and means to carry out the sum.
