考慮工件的空間尺寸及空間回轉運動等因素,防止轉動部件在工作中發生碰撞。然后考慮結構的合理性,根據傳動件的大小確定焊接結構的大小,為L臂安排配重,然后對整個結構進行強

摘要:焊接變位機也已成為制造業的一種不可缺少的設備,在焊接領域把它劃為焊接輔助機。就型式系列和品種規格而言,已問世的約有十余個系列,百余個品種規格,正在形成一個新興行業。  
本題目是設計前車架全方位焊接變位機。它要求具有兩個自由度,實現前車架焊接過程中可繞相互垂直的軸回轉360º,被焊工件的任一條焊縫都可以轉到平焊或船焊位置,避免立焊和仰焊,從而保證焊接質量,改善工人勞動強度和工作環境,提高生產效率。34752
設計的具體過程是根據預定的載荷和要求進行L臂結構設計和機架結構設計。這兩部分主要為焊接結構,首先進行受力分析,了解不同情況下受彎矩和扭矩的大小確定截面的大致形狀和板厚。然后考慮工件的空間尺寸及空間回轉運動等因素,防止轉動部件在工作中發生碰撞。然后考慮結構的合理性,根據傳動件的大小確定焊接結構的大小,為L臂安排配重,然后對整個結構進行強度校核。最后繪制相關的零件圖、總裝圖。  
選用的方法主要是機械設計的相關知識,使用到的有材料力學、機械設計、UG等。  
畢業論文關鍵詞: 焊接變、夾具設計、結構設計。
 5 tons loader front frame welding positioner overall design
Abstract:
  Welding positionerhas become an indispensable manufacturing equipment, which is zoned welding assistant engine in the welding area. Patterns and varieties of specifications on the series, has been developed, some over 10 series, more than 100 varieties of specifications, a newly emerging industries.  
The topic is design the front frame full displacement welding positioner.It requires a two degrees of freedom, realize the front frame welding process can turn around the perpendicular axis 360 º, the welding work pieces of any one of the welding line can turn to flat welding or ship welding position, avoid set up welding and welding, so as to ensure welding quality,improve the labor intensity and working environment,improve production efficiency.   源`自*六)維[論*文'網www.aftnzs.live
The specific design process is according to the predetermined load and requirements for L arm structure design and frame structure design. The two parts mainly for welding structure, first mechanics analysis, understanding the different cases by bending moment and the size of the torque, determine the general form of the section and thickness. Then consider the size and space turn sports factors, prevent rotating components work in a collision. Consider the rationality of the  structure, according to the size of the transmission parts to determine the size of welding structure, for L arm counterweight arrangement, and then for the whole structure strength check. Finally draw relevant parts graph, assembly drawing.  
The selection of the method is mainly related knowledge of mechanical design, using material mechanics, the mechanical design, UG.  
Keywords: welding ,positioner, fixture design, structure design.
