Abstract

The invention relates to an online coping device for a cutting tool of a numerical control tool, which effectively solves the online coping problem of the cutting tool. The device is a polishing head spindle, one end of which is provided with a tooth shaped belt wheel and the other end is provided with an elastic clamp polishing head which is provided with an amplitude transformer, a transducer is arranged on a first half axis which is connected with the amplitude transformer at the lower side by a thread and which is arranged in a shell of the polishing head , the shell is arranged in an installation seat of the polishing head, the same side of a grinding head spindle and a tooth-shaped belt of the polishing head is provided with the tooth-shaped belt wheel of the grinding head, the grinding head is arranged at the lower part of the amplitude transformer of the grinding head by the elastic clamp, the upper part of the amplitude transformer is provided with a piezoelectric ceramic transducer of the grinding head, the piezoelectric ceramic transducer of the grinding head is arranged on the first half axis of the grinding head, is connected with the amplitude transformer of the grinding head at the lower side by thread on the first half axis of the grinding head and is arranged in the shell of the grinding head, the shell is arranged in the installation seat, and a motor, the tooth-shaped belt wheel of the polishing head and the tooth-shaped belt wheel of the grinding head are integrated into a whole by the tooth-shaped belt. The online coping device can be effectively used for coping of the blade of the numerical control tool and is a large innovation in the field of the numerical control tool.

Description

1. Technical field [0001] The invention relates to a processing machine, in particular to an on-line tool grinding device for a numerically controlled machine tool. 2. Background technology [0002] With the advancement of science and technology, machining machine tools are gradually developing in the direction of digitization, automation and high speed. In terms of the tools used, the extensive use of disposable tools is inevitable for the development of digitalization, automation, and high-speed machining machine tools, such as machine-clamp blades that do not need to be reground. Disposable knives have very prominent advantages: [0003] 1. Its own geometric dimension has high precision, repeat positioning and strong interchangeability; [0004] 2. It is convenient and quick to load and unload. After replacing the new blade, it can be put into use quickly without recalibrating the blade, which lays the foundation for the high efficiency of the CNC machine tool. [0005...

AI Technical Summary

Problems solved by technology

[0006] 1. A blade ranges from twenty or thirty yuan to hundreds of yuan, and its utilization rate (by weight) is less than one-thousandth. Once it cannot be used, it has to be thrown away, which greatly wastes resources;

[0007] 2. After one tool tip is worn out, another tool tip has to be replaced. Such frequent replacement will damage the screw on the one hand and stop production on the other hand, which limits the further improvement of the efficiency of CNC machine tools.

Flank wear further intensifies the friction between the tool and the workpiece, increases the feed resistance, easily generates machining vibration, and affects the roughness of the workpiece surface; boundary wear further deteriorates the cutting performance of the tool (the negative rake angle of the tool is further increased), The normal cutting of the tool gradually becomes extrusion cutting

Both flank wear and boundary wear will rapidly increase cutting heat, which in turn will further aggravate flank wear and boundary wear
