A four-station four-axis turning tool sharpening CNC machine tool

Abstract

The invention provides a four-station four-axis turning tool sharpening CNC machine tool, comprising a machine bed body, a grinding wheel, an electric tool rest, a grinding wheel driving device and an electric knife rest driving device are arranged on the machine tool bed, and the electric knife rest driving device includes Longitudinal driving device and horizontal driving device; the longitudinal driving device is used to drive the electric tool post for longitudinal movement; the horizontal driving device is used to drive the electric tool post for horizontal movement; The straight rotary drive device is used to drive the electric tool post for vertical rotary motion; the grinding station conversion device is used to drive the electric tool post to change the grinding station; it can realize the fast and fully automatic operation of the grinding process, reducing the operator's experience. Insufficient level and the impact on the quality of turning tool sharpening, it is convenient to realize the standardized operation of turning tool sharpening, it can realize the automatic grinding of four turning tools in sequence, and the work efficiency is high.

Description

technical field [0001] The invention relates to a turning tool sharpening equipment, in particular to a four-station four-axis turning tool sharpening numerical control machine tool, which belongs to the field of mechanical technology. Background technique [0002] During the turning process, the sharpening of the turning tool directly affects the efficiency and quality of the cutting process. After a period of use, the turning tool will not meet its requirements due to wear. Frequent sharpening is required, so the level of sharpening efficiency will also affect production efficiency. [0003] At present, turning tools are usually sharpened manually on a grinder based on experience before use. The angle error of the grinded tool is large, and it is difficult to ensure a reasonable angle during cutting, which affects the processing efficiency and quality. At the same time, due to the poor balance of the grinder , The impact of the grinding wheel causes the tool to vibrate vi...

Problems solved by technology

[0002] During the turning process, the sharpening of the turning tool directly affects the efficiency and quality of the cutting process. After a period of use, the turning tool will not meet its requirements due to wear. Frequent sharpening is required, so the level of sharpening efficiency will also affect production efficiency

[0003] At present, turning tools are usually sharpened manually on a grinder based on experience before use. The angle error of the grinded tool is large, and it is difficult to ensure a reasonable angle during cutting, which affects the processing efficiency and quality. At the same time, due to the poor balance of the grinder , the impact of the grinding wheel causes the tool to vibrate violently, it is difficult to keep the tool stable when holding the tool, and it is prone to micro-serrated defects on the edge of the tool. In severe cases, cracks and chipping will also occur, and it is easy to cause safety accidents

[0004] Now, there are also special turning tool grinding machines and sharpening machines on the market, but because of their poor flexibility, inconvenient use, low degree of automation, low precision, low efficiency, and high requirements for the technical level of operators, the popularization and use of them are greatly restricted.
