Background
A welding tool for a cargo boom is designed for standardizing the manufacturing of the cargo boom, the cargo boom of a tower crane is formed by splicing a plurality of short arms according to the whole length requirement, the cargo boom needs to have different length combination requirements according to the change of an operation environment, the cargo boom is divided into three types of 5-meter sections, 10-meter sections and arm end sections according to the length for facilitating the splitting and combining of the different length requirements, the cargo boom is divided into two types of a square section and a triangle section according to the section, the cargo boom of each specification needs one welding tool to manufacture a standard workpiece, the size requirement of the workpiece is very high for facilitating the smooth combination, but the appearance size of the cargo boom is different according to the series and the model of a tower crane, the tools manufactured in different sizes and specifications are different, the manufacturing field is required to be large, and the tools are more. The result is unfavorable for workshop site layout and production management, if the defects of more tools and large occupied area need to be solved, the number of the tools needs to be reduced as much as possible, and meanwhile, the production requirements of the crane booms with different dimensions and specifications need to be met as much as possible.
In the practical use of the tool, according to the production process flow of the crane boom, in order to smoothly assemble and weld a weldment and smoothly demould a welded workpiece, the positioning and clamping devices of the upper chord rod and the lower chord rod of the tool are required to be movable, can be quickly positioned and clamped, keep the state unchanged and are beneficial to rivet welding of the weldment, and the positioning and clamping state needs to be quickly released to separate from the workpiece after the welding of the workpiece is finished, so that the positioning and clamping devices are required to be adjusted flexibly, positioned accurately and powerfully. The fixture is generally connected with a workpiece by a connecting chuck and utilizes the fixed position of a positioning pin shaft, and has the advantages of simple structure, accurate and stable positioning connection and the defects of thick and heavy connecting parts, low working efficiency and labor waste of operators. The later stage has improved frock location clamping device in order to improve frock availability factor, has two kinds of modes, and one is adopts the lead screw top to advance and presss from both sides tight work piece, and efficiency has improved but the accurate easy aversion in location, causes the work piece size to have the deviation. The other type is that the hydraulic oil cylinder jacks to clamp the workpiece, and the hydraulic oil cylinder has the advantages that power is transmitted by using pressure energy of liquid according to the working principle of hydraulic transmission, mechanical energy is converted and transmitted to the actuating mechanism, and the positioning and clamping of the workpiece are controlled by controlling the adjusting device, so that the smooth riveting and welding of the workpiece are facilitated. Thus, the defect of improving the operation of the screw rod is also achieved, and the working efficiency is improved. The most important disadvantage is that the working medium of the hydraulic system is hydraulic oil, which leaks out during operation and pollutes the working environment.
To above problem, need urgently to research and develop availability factor and the commonality that a section improves the frock for the production progress alleviates staff's load, avoids the pollution to operational environment and occupy the too much in place, and the special design has improved the integration utilization mode of frock positioning and clamping device and frock, reaches the high-efficient rate of utilization and the commonality of frock.
