Abstract

The invention discloses a designing method of the positioning welding for a forklift portal frame based on the streamlined production, a portal frame welding positioner and a welding method of the forklift portal frame . The designing method comprises the steps that the statistics on the welding workload of each welding robot is conducted, the welding station is divided according to the production tact time, the production process layout is planned, the working position, structure form, positioning and clamping mode of the positioner are determined according to the welding position of the workpiece welding seam, and the power source of the positioner is selected; and the welding robot simulating is conducted according to the structure and welding position of the positioner, the structureof the positioner and the compliance of the theoretical weldability rate are verified, the action sequence of each station positioner and the coordination requirement with the robot action are designed, and a PLC control procedure is programmed for automatic welding. By means of the designing method, through the online process layout mode, the tediousness of the workpiece hoisting is reduced, thecompression of the auxiliary working time is maximized, the efficiency is further improved, and the positioning welding of the complex welding seam is achieved through the sequenced process thinking.

Description

technical field [0001] The invention relates to the technical field of forklift manufacturing, in particular to a design method for positioning welding of a mast of a forklift based on streamlined production, a mast welding positioner and a welding method thereof. Background technique [0002] Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. The mechanism for lifting goods by forklifts is also called mast. In the process of mast production, mast welding is usually produced by manual welding or welding robot workstation welding. Manual welding has low production efficiency, high labor intensity, and poor consistency; welding by welding robot workstations takes a long time to assist, streamline production cannot be achieved, and investment costs are high. Contents of the invention [0003] In view of the above-mentioned defects or deficienc...
