Description
Technical Field
The invention relates to machining equipment, in particular to numerical control gear machining equipment.
Background
In general, cutting is a mechanical operation of cutting a workpiece while rotating a tool, and the workpiece itself is easily damaged not only when a tool chip is easily generated in the tool during cutting. Therefore, in the prior art, corresponding sensors are usually used to detect the tool state during or after machining. For example, the defect is inspected by using an optical fiber reflection type photoelectric switch for detecting the presence or absence of a cutting edge of the tool, or a tool attachment position detection circuit for outputting a tool attachment position detection signal, and by comparing a detection signal from the reflection type photoelectric switch with the tool attachment position detection signal.
However, in the prior art, the optical fiber reflection type photoelectric switch is generally high in cost and is easily interfered by other light sources to cause errors. In order to accurately detect an abnormality such as the shape or size of the cutting tool, it is necessary to perform fine adjustment of the measurement position using an adjustment screw in the machine tool, and it takes a long time to confirm.
Disclosure of Invention
The technical scheme is as follows: in order to solve the technical problem, the invention provides a numerical control gear machining device, which comprises a numerical control part, a rotating shaft, a main shaft, a cutting tool and an eddy current sensor, wherein the numerical control part is provided with a first end and a second end; the rotary shaft is used for holding and rotating a cutting tool which is positioned below the rotary shaft and is connected with the main shaft, the eddy current sensor is used for detecting the state of the cutting edge of the cutting tool, the upper end of the main shaft is provided with a rotary encoder, and the eddy current sensor is electrically connected with the digital control component.
