Description

Technical Field

[0002] With the rapid development of my country's logistics industry, ports and railways, as hubs of transportation, play the role of "pumping stations" in the national economic logistics system. The market demand for high-lift and large-tonnage lifting engineering machinery is becoming more and more urgent. Lifting engineering machinery includes cranes, truck cranes, reach cranes, forklifts and other lifting machinery. Compared with large-scale lifting equipment such as yard cranes and quay cranes, they are more flexible, occupy less space, and have a wide range of applications, which can meet market demand. The square box-type boom is an important load-bearing component of lifting engineering machinery. In the machining production of the square box-type boom, the existing positioning and clamping tooling uses flexible fixing blocks, pressure rods, and pressure plates. First, the positioning and installation of the pads are carried out on the machining equipment platform, and then the boom is hoisted onto the pads. Then, the pressure plates and bolts are used to fix and clamp the boom in the height direction. Due to the poor versatility and low stability of the existing clamping methods, replacing arm structural parts of different sizes requires replacing pads and pressure blocks, which has low efficiency and high production labor intensity. At the same time, the clamping effect is poor, and the workpiece vibrates greatly during machining, affecting the machining accuracy. When performing large-scale arm machining, the clamping efficiency is low and the machine tool tool positioning time is long, which seriously restricts the daily production capacity of the machining equipment.
