Profile multi-axial multi-station automatic drilling and milling combination production line and processing method thereof

Abstract

The invention discloses a multi-axis and multi-station automatic section bar drilling and milling combined production line and a section bar processing method utilizing the production line. The production line comprises a main multi-station drilling machine, an automatic feeding machine and a CNC system, wherein the automatic feeding machine and the main multi-station drilling machine are butted with each other, so that the working planes of the two main machine bodies are in the same plane; the main multi-station drilling machine comprises a rack; a gantry is mounted on the rack; at least one drilling device for drilling the side surfaces of a workpiece, at least one drilling device for drilling the top of the workpiece and a pressing mechanism are arranged on the gantry; the drilling devices for drilling the side surfaces of the workpiece are driven by a lifting mechanism to move up and down in the vertical direction; the pressing mechanism is used for clamping the workpiece; and the CNC system controls the automatic feeding machine, the drilling devices, the lifting mechanism and the pressing mechanism to perform movement.

Description

technical field [0001] The invention relates to the field of numerical control machining, in particular to a multi-axial and multi-station automatic drilling and milling combined production line for profiles and a processing method thereof. Background technique [0002] At present, China's manufacturing industry is in a period of vigorous development, and the demand for drilling of various workpieces is very large. Therefore, CNC drilling machines are being used more and more widely, which also makes the current domestic CNC drilling machines have a large market demand. . At present, most of the CNC drilling machines produced by domestic enterprises only have one drill bit. When faced with large-scale processing tasks, the work efficiency is low, and the labor intensity of the operators is relatively high. [0003] When increasing the number of drill bits, it not only requires an increase in the space structure, but also ensures a high relative position accuracy between eac...

AI Technical Summary

Problems solved by technology

[0003] When increasing the number of drill bits, it is not only required to increase the space structure, but also to ensure a high relative position accuracy between each processing head. At the same time, due to the increase in the number of drill bits, the machine tool has to bear more The cutting force will reduce the stability and precision of the machine tool

[0004] However, when there are holes on multiple sides of the workpiece, it is necessary to perform secondary positioning before drilling, which increases the difficulty of processing, reduces the processing efficiency, and greatly reduces the processing accuracy of the workpiece.

[0005] Although the multi-axial punching machine can also realize the multi-axial multi-station hole making of the workpiece, its hole making accuracy is obviously lower than the drilling accuracy, which cannot meet the needs of high-precision machining
