Description
Technical Field
The utility model relates to the technical field of industrial control automation, in particular to a CNC cutter breaking sensing device.
Background
In the prior art, cn201610130447.X discloses that in the numerical control machining process, cutter breakage may be caused by reasons such as excessive cutting force and cutter aging. If the situation of cutter fracture cannot be detected in time, the processing quality and the processing efficiency can be affected. Particularly, in the production process of large batch and multiple working procedures, large-size cutters are generally adopted for rough machining, smaller-size cutters are respectively adopted for semi-finishing and finishing, and if breakage of the large-size cutters cannot be detected in time, continuous breakage of the small-size cutters in the subsequent working procedures can be caused, so that the production flow is seriously disturbed. At present, two types of cutter fracture detection methods are mainly adopted. The non-real-time detection method is used for judging whether the cutter is broken or not through methods such as cutter tip contact, light beam detection, computer vision image processing and the like. The method is applied before machining or after machining, the cutter must be moved to a designated detection position, the cutter fracture condition in the machining process cannot be judged, the machining efficiency is affected, and the method has a large limitation. The other is a real-time detection method, and judgment and detection are carried out through key features before and after the cutter breaks in the processing process. For example, an induction type micro-current cutter breaking detection circuit detects the change of induced current generated in the drilling process through a sensor, and a PC (personal computer) compares the current position with an average value in real time to judge whether a cutter is broken or not; the method is suitable for the condition of drill bit processing, is not suitable for a common milling processing technology, is complex in device, is inconvenient to acquire signals, and has certain limitation in practical production and application. A cutter breakage monitoring method of processing and forming equipment judges whether cutter breakage occurs by comparing the speed difference between the idle rotation speed and the real-time processing rotation speed of a main shaft with a reference rotation speed difference; the method is suitable for the numerical control machine tool with the open-loop control of the rotating speed, and the hollow load rotating speed and the actual rotating speed can generate larger change in the processing process, and is not suitable for the numerical control machine tool with the closed-loop control of the rotating speed due to the small fluctuation range of the rotating speed in the processing engineering of the rated rotating speed.
CNC devices are short for computer numerical control machine tools, which are automated machine tools controlled by programs, capable of logically processing programs defined by control codes or other symbolic instructions, and decoding them by a computer to cause the machine tools to perform defined actions; the existing CNC broken cutter sensing device can realize unattended operation and automatic operation for a long time under the auxiliary cooperation of a robot, but cannot automatically sense broken cutters, and a large amount of waste products or machining omission can be generated.
There are therefore drawbacks to the prior art that require improvement.
