Heavy truck cab welding fixture by order of action to achieve the floor, front wall, rear side of the three assembly automatic assembly, this idea comes from the overlapping structure of the product, flat car "three assembly" overlapping forms. According to the characteristics of the product, when "three assembly" combination, must follow before the first assembly of Wai Wai backside after assembly principle, pan and flip mechanism and use. Action sequence: an action cylinder, front wall fixture slide pan; cylinder 2 Action heavy truck cab, before flipping around the fixture 90 °, this time around the front side of the floor assembly fit assembly in place; Cylinders 4 action, posterior Flip around the fixture 90 °; cylinder 3 action, rear side clamps slide down, then around the back side of the floor assembly turned falls along the Chinese heavy truck cab pictures, and the upper lap dash top, complete "three assembly" in the space of automatic assembly. This example proved: the use of a hydraulic cylinder control of large slide flip and pan, can ensure the smooth running of the institution and reliability. Heavy truck cab consumers increasingly high performance requirements, national regulations have become more stringent in the case of vehicle dynamics to meet the Shandong heavy truck cab, the pursuit of comfort and good vibration characteristics of Jinan heavy cars Steam cab, comfort, require manufacturers to produce safer, more energy efficient, more environmentally friendly cars. The flat-head light truck cab, its vision, body length and wheelbase smaller, reduce automobile curb weight, improve mobility, and gradually become the mainstream of truck cab. Because the vehicle vibration system is particularly complex, according to the actual situation needs to be suitably simplified model light truck, the vehicle body frame and other quality into the unsprung mass suspended two parts quality and wheel axles and the like. Tire has a certain flexibility, without considering the dynamics of the tire, to determine the system's mass, stiffness and damping parameters and external incentives.
