Research on support device for machining of box-type parts
With the continuous development of welding technology,more and more box-type parts are initially processed by welding and then precision machined on machine tools.To prevent deformation caused by machining,support devices are added inside the box-type parts during precision machining on machine tools.For box-type parts with relatively small height and greater depth,such as those with a height less than 300 mm and depth greater than 1 500 mm,it is difficult to place the support device at the designated position because the reach of arms is limited,which results in inadequate support and consequently leads to significant deformation after machining.To address this issue,a support device was studied.Using UG three-dimensional modeling technology and virtual prototype technology,product design and virtual assembly were performed to validate the practicality and feasibility of the support device.The use of the support device saved more than 25%of the manufacturing cycle time for box-type parts with small height and great depth.Additionally,the device was equipped with a pressure sensor and display system that could monitor and display the support force in real-time,reducing the time required to adjust the support device by more than 30%.The support device effectively solved the difficult support issue encountered during the machining process of box-type parts with small height and great depth,improved the machining accuracy,enhanced the manufacturing quality of box-type parts,and brought economic benefits to enterprises.
