Abstract
The invention provides a main shaft of a machine tool for processing oil nozzle type workpieces, wherein when the main shaft generates abnormal shock if an abnormal condition occurs in the grinding process, the machine tool may stop running or change various parameters to correct the grinding state, thus ensuring the safety of the equipment and the staff. The main shaft comprises a main shaft rotating shaft and a main shaft base, wherein the main shaft rotating shaft is sleeved in the main shaft base, and wherein a sonic sensor rotor is sleeved to the main shaft rotating shaft; a sonic sensor stator is mounted on the main shaft base; and the sensing surfaces of the sonic sensor rotor and the sonic sensor stator are mounted in opposition to each other.
Description
Technical field
The present invention relates to process the technical field of the machine tool structure of oil nozzle class workpiece, be specially the machine tool chief axis of processing oil nozzle class workpiece.
Background technology
The grinding area of oil nozzle is not only thin but also dark, and the emery wheel extension bar also must be not only long but also thin so, and rotating speed must be very high, reaches 70000-100000r/min.Under the so high rotating speed, if emery wheel when feed and workpiece produce collision, and the operative employee is difficult for finding, digital control system is not known yet; This situation of leaving develops, and consequence can be very serious, and gently then emery wheel breaks up; The emery wheel extension bar twists off, and heavy then electric main shaft damages, even threatens personal safety.
Summary of the invention
To the problems referred to above; The invention provides the machine tool chief axis of processing oil nozzle class workpiece, it makes when having occurred improper situation in the grinding process, thereby when making main shaft produce improper vibrations; Lathe can be out of service or be changed various parameters and correct the grinding state, guarantees equipment, personnel's safety.
The machine tool chief axis of processing oil nozzle class workpiece; Its technical scheme is such: it comprises main axis rotation axle, main shaft support; Said main axis rotation axle sleeve is loaded in the said main shaft support; It is characterized in that: be set with the sonic sensor rotor on the said main axis rotation axle; On the said main shaft support sonic sensor stator is installed, the sensitive surface of the rotor of said sonic sensor, the stator of sonic sensor is installed in opposite directions.
After adopting structure of the present invention; When improper situation having occurred in the grinding process; Will make the main axis rotation axle produce improper vibrations; Thereby sonic sensor will send alarm signal to system; Make lathe out of service or change various parameters and correct the grinding state, guarantee equipment, personnel's safety.
