Dissimilar damper pressing machine has defect separately, gives an example as follows:
1. adopt pneumatic press-fit approach, it is accurate that this press-fit approach press-fits insufficient height, and corresponding various and multiple damper, and the difficulty of remodeling easily causes equipment failure rate higher, and maintenance is frequent.
2. adopt hydraulic pressure press-fit approach, this press-fit approach is because adopt hydraulic pressure, thus press-fit highly more accurate, but because adopt Hydraulic Station, so equipment noise is larger, and easily produce greasy dirt, contaminated environment, once and equipment generation fault, maintenance cost is higher, can not keep in repair corresponding production the short time.
3. nut screwing clamping adopts pneumatic air pressure gun, this mode very easily causes damper moment of torsion unstable, and whether needing operative employee to carry out secondary check, to demarcate damper moment of torsion qualified, has increased workman's workload, increase the weight of workman's labour intensity, strengthened the qualified decision factor of workpiece.And human factor proportion is bigger than normal during operation, the damper nut torque situation unstable and that nut breaks that the general idea operating due to workman causes happens occasionally, and qualification rate is low.
4. adopt single-piece list station, this mode once can only press-fit a damper, so corresponding same vehicle just needs left and right two complete equipments, and variety classes damper needs different press-loading devices, once need larger input cost and installing space, and need to configure several workmans and operate respectively.
5. adopt single-piece double, this mode can synchronous press mounting two dampers in left and right, single-piece list station press-fit approach makes moderate progress relatively, but when line body has two or more vehicles, just need to increase in addition a set of equipment corresponding, also exist and increase input cost and installing space.
