Robot milling double-shaft compound cutter device and method

Abstract

The invention relates to a robot milling double-shaft compound cutter device and a method, and belongs to the field of cold and hot compound working in machining. The device consists of a robot driving unit, a connecting bracket, a compound cutter device and a machined workpiece. The compound cutter device comprises a robot connecting shaft, an upper cover, a bearing, a gear set, a shank, a springchuck, milling cutters and a shank cap. The robot driving unit drives the milling cutters in the compound cutter device to rotate to machine the machined workpiece. The robot driving unit is fixedlyconnected with the robot connecting shaft of the compound cutter device to drive a driving gear. The driving gear drives two driven gears to oppositely rotate, so that the two milling cutters are driven to oppositely rotate to realize synchronous milling of double shafts by double side surfaces of the machined workpiece. The device is simple in structure, convenient to install and lower in cost, and replaces the milling cutters to change the side surface sizes of the machined workpiece, namely the thickness of a wall, so as to achieve the machining precision and the surface quality requirements.

Description

technical field [0001] The invention relates to a structure and method of a composite cutting tool for reducing material and milling by a robot, which belongs to the field of combined cold and hot processing in mechanical processing, and is tooling equipment for milling and cutting material leveling in the integrated composite manufacturing of adding and subtracting materials, as well as installation and use methods. Background technique [0002] In recent years, under the background of resource saving and high-efficiency manufacturing, the additive manufacturing technology based on the "additive" processing mode has shown broad application prospects in the manufacture of thin-walled parts with complex shapes. Additive manufacturing technology is a technology that uses CAD design data to manufacture solid parts by accumulating materials layer by layer. Additive manufacturing technology represents the development trend of production mode and advanced manufacturing technology....

AI Technical Summary

Problems solved by technology

It can be seen that the control of the forming shape is the main bottleneck of the additive manufacturing technology of metal parts. This is because the STL format and two-dimensional layering technology are used in the discretization process of itself, resulting in dimensional errors and step effects.

Generally speaking, the smaller the layer thickness, the higher the accuracy, but the longer it takes, which increases the cost
