Automatic robot milling machining device for inner walls of cylindrical parts

Abstract

The invention provides an automatic robot milling machining device for the inner walls of cylindrical parts. The automatic robot milling machining device mainly comprises a mechanical arm operation system, a wrist body system, a main shaft system and a rotation system. The mechanical arm operation system drives the wrist body system to move; the wrist body system drives the main shaft system to move; a tool of the main shaft system rapidly rotates under the driving of an air source; and the rotation system drives a workpiece to rotate at a constant speed. The device provided by the invention is simple and compact, and applicable to milling machining for the inner walls with different thicknesses, of various magnesium alloy parts. The specific structural dimensions can be specially customized according to the different magnesium alloy parts; and the design flow is as follows: the dimensions of a rotation chuck are selected according to the dimensions of the machined workpiece, the rotational speed of a main shaft, the dimensions of the tool and the rotational speed of the rotation chuck are selected according to material characteristics, and a preset program flow of a robot is determined according to the structures of the inner walls of the parts. The automatic robot milling machining device is quite suitable for ultraprecision machining.

Description

technical field [0001] The invention relates to a part processing device, in particular to a robot automatic milling device for the inner wall of a cylindrical part. Background technique [0002] As an important component of a certain product, the wall thickness of the cylindrical part is the key technical indicator. At present, the parts are mostly cast, and the casting allowance is large and uneven. Due to the complex structure of the inner cavity of the part and the poor processing flexibility of the machine tool, most of the complex There will always be interference during the processing of the inner wall of the part, and the part cannot be directly processed in place. After the machining of the machine tool, the part of the inner wall of the part that has not been machined needs to be manually polished. until the wall thickness requirements are met. The processing efficiency of the inner wall of the part directly restricts the cycle of the entire industrial processing ...

AI Technical Summary

Problems solved by technology

Due to the large area to be polished on the inner wall of the part, manual grinding has low efficiency, many measurement points, high quality risk, poor working environment, and high labor intensity. Especially the magnesium alloy dust is combustible, and the dust and noise generated during the operation Contamination seriously threatens the health and safety of operators
