福州流水线：底盘总装配线 ：双行道板式输送链：链板采用优质花纹钢，钢板厚7mm，对带支撑的面板用筋板进行加强，链板长1m宽250mm，线长189m，两道链板内侧距离1m。台板用Q235 8mm钢板制作，保证一定强度，在承重时不变形。链条其结构为可拆式，内外板片厚度满足其抗拉强度要求，链片厚不低于10MM，其材质为16Mn，轴销为40Cr钢并经调质处理，滚轮表面硬度不小于HRC38，链条滚轮内安装轴承可降低运行阻力，避免爬行，且轴承内加润滑脂：由专业厂家按行业标准制造，质量保证；销轴、滚轮均经热处理工序，链条链片表面须经抛丸防锈处理。
Assembly line: Chassis assembly line: The assembly line: Chassis assembly line. The conveying method is divided into two sections, namely, the first 14 stations use bridge-type submerged chain conveyors, and the last 9 stations use double-lane slab conveyors. The length of each station is 8m, there are 23 parking spaces, and the chain speed is 0.8m/min-3m/min.
The submersible drag chain of the assembly line adopts continuous operation mode, and employees work on both sides. There are parts racks on both sides, which are transported to the assembly line by manual, KBK, or aerial hanging. Motor reducer adopts SEW motor
Each frame on the submersible drag chain requires 2 craft carts, and the center distance between the two carts can be adjusted to meet different wheelbase models. The craft trolley supports the upper and lower wing surfaces of the longitudinal beam of the frame, and can also support the front and rear axles of the chassis through the bracket transformation. A layer of high-strength polyurethane liner shall be covered on the supporting surface of the support trolley in contact with the frame.
Assembly line: Chassis assembly line: Front single plate chain: The structure of the chain is detachable, the thickness of the inner and outer plates meets its tensile strength requirements, the thickness of the chain is not less than 10MM, the material is 16Mn, the shaft pin is 40Cr steel and the Quenched and tempered, the surface hardness of the rollers is not less than HRC38. Bearings installed in the chain rollers can reduce running resistance and avoid crawling. Grease is added to the bearings: manufactured by professional manufacturers according to industry standards, quality assurance; pins and rollers are In the heat treatment process, the surface of the chain link must be shot blasted to prevent rust.
Assembly line: Chassis assembly line: Two-lane plate conveyor chain: chain plates are made of high-quality patterned steel, steel plate thickness is 7mm, and the supporting panels are reinforced with ribs. The chain plate length is 1m wide and 250mm wide, the line length is 189m, and the inner side of the two chain plates The distance is 1m. The table plate is made of Q235 8mm steel plate to ensure a certain strength and not deform when bearing a load. The structure of the chain is detachable, the thickness of the inner and outer plates meets its tensile strength requirements, the thickness of the chain is not less than 10MM, the material is 16Mn, the shaft pin is 40Cr steel and is quenched and tempered, and the surface hardness of the roller is not less than HRC38. Bearings installed in the chain rollers can reduce running resistance and avoid crawling. Grease is added to the bearings: manufactured by professional manufacturers in accordance with industry standards, quality assurance; pins and rollers have undergone heat treatment, and the surface of the chain must be shot blasted to prevent rust deal with.
Assembly line: Chassis assembly line: The electrical control control system is PLC control, and the speed can be set through the equipment management computer system.
Note: The speed and tempo of the front and rear conveyor systems must be matched and synchronized; the transition from the craft trolley to the double-plate chain is smooth and smooth.
The above assembly line: The chassis assembly line information is compiled and released by Jingliu.
