Description

Automatic chip cleaning device and method for CNC lathe machining

Technical Field

The invention relates to an automatic chip cleaning device and method for numerically controlled lathe machining, belonging to the technical field of automation equipment.

Background technique

When a CNC lathe processes parts, the parts are clamped on the lathe spindle, and the turning tool turns the rotating workpiece to process the inner and outer surfaces of the workpiece. The processing process includes rough turning and fine turning. The former removes excess material from the blank, and the latter ensures the size and position accuracy of each processing surface of the part. The manufacturing, sharpening and installation of the turning tool are relatively simple.

During the turning process, the removed chips are not easy to break off and are easily entangled in the tool, part surface and inner hole. Failure to clean them in time will cause problems such as part size deviation, increased surface roughness value, increased tool wear rate or tool edge breakage. Traditional chip cleaning methods mainly rely on manual chip cleaning, and the entire processing process requires human monitoring and intervention, resulting in low CNC lathe processing efficiency and the inability to further improve the degree of automation.

Summary of the invention

The barbed chip hook is installed on the cutter disc, the installation angle is parallel to the X-axis of the CNC lathe, the end is set as a barbed structure, and the barb length of the chip hook is determined according to the inner hole cutting requirements of the part to be processed.

The CNC lathe is preset with a machining control program for controlling the coordinated movement of various components to complete the machining of the parts to be machined and the chip cleaning. The machining control program determines the motion parameters and cutting parameters of each component according to the requirements of the machining task.

The automatic chip cleaning method for CNC lathe machining realized by the automatic chip cleaning device for CNC lathe machining comprises:

Before the chip cleaning task begins, connect the booster device to the coolant tank of the CNC lathe;

After the processing is completed, the tool is controlled to move to the rotary wire brush for repeated movements to remove the chips wrapped around the surface.

If the processing part of the part to be processed is the outer surface, the barbed chip hook is not controlled to move and the processing process is terminated; if the processing part of the part to be processed is the inner hole, the barbed chip hook is controlled to move repeatedly in the hole to remove the chips in the hole and the processing process is terminated.
