Embodiment 1

[0031] In this embodiment, a tool handle with a built-in vibration sensor, such as figure 1 As shown, it includes a tool handle main body 100, a data acquisition circuit board 400, a vibration acquisition component, an electric energy receiving component and an electric energy sending component. The middle part of the tool handle main body is provided with an inner hole 104, and the data acquisition circuit board and the vibration acquisition component are installed in the inner hole. Among them, the power receiving component is arranged on the outer surface of the handle main body, the power sending component is installed coaxially with the tool handle main body, the power sending component and the power receiving component are arranged facing each other with a gap left, and the power sending component and the power receiving component conduct wireless energy Transmits and supplies power to the data acquisition board. Among them, the power receiving component and the power se...

Embodiment 2

[0040] This embodiment is a tool holder with a built-in vibration sensor. The difference between this embodiment and Embodiment 1 is that, as Figure 9 As shown, the power sending assembly also includes a signal receiving coil 211, the signal receiving coil is arranged in the second casing, the power receiving assembly also includes a signal sending coil 311, the signal sending coil is arranged in the third casing, and the signal receiving coil is facing Signal sending coil. The vibration signal stored in the data acquisition circuit board can be wirelessly transmitted through the signal receiving coil and the signal sending coil, which is convenient for operation and use.

[0041] When in use, in addition to obtaining vibration data by means of a data storage card, data can also be obtained by means of wireless transmission. Such as Figure 9 As shown, a signal receiving coil 211 is added to the power sending component, and a signal sending coil 311 is added to the power re...

Abstract

The invention discloses a knife handle with a built-in vibration sensor. The knife handle comprises a knife handle body, a data acquisition circuit board, a vibration acquisition assembly, an electricenergy receiving assembly and an electric energy sending assembly, wherein an inner hole is formed in the middle of the knife handle main body; the data acquisition circuit board and the vibration acquisition assembly are installed in the inner hole; the electric energy receiving assembly is arranged on the outer surface of the knife handle body; the electric energy sending assembly and the knifehandle main body are coaxially installed; the electric energy sending assembly and the electric energy receiving assembly are oppositely arranged; a gap is reserved between the electric energy sending assembly and the electric energy receiving assembly; and the electric energy sending assembly and the electric energy receiving assembly conduct wireless electric energy transmission and supply power to the data acquisition circuit board. According to the knife handle with the built-in vibration sensor, the problem that the propagation path of a vibration signal is long during cutting vibrationmeasurement is solved, the signal-to-noise ratio of the vibration signal is improved, and the subsequent processing difficulty of the vibration signal is reduced.

Description

technical field [0001] The invention relates to the technical field of tool holders for measuring vibration signals, in particular to a tool holder with a built-in vibration sensor. Background technique [0002] At present, the signal acquisition in the metal cutting process mainly collects the temperature of the cutting tool and the deformation of the cutting tool to analyze the cutting performance. There are few literature reports on the collection of vibration signals generated during the cutting process. Changes in stress, temperature and other cutting process parameters during the cutting process will lead to changes in vibration signals. Therefore, vibration signals can be used as a comprehensive reflection of cutting stability. reference index. [0003] Metal cutting machine tools belong to mechanical equipment. The general method for collecting vibration signals of mechanical equipment is to attach vibration sensors to the frame position close to the vibration sourc...
