Intelligent high-speed motorized spindle realizing integration of multi-parameter detection

Abstract

The invention discloses an intelligent high-speed motorized spindle realizing integration of multi-parameter detection. The intelligent high-speed motorized spindle comprises a rotating shaft, a stator and a rotor, wherein the rotating shaft is arranged inside a housing; the stator is fixed to the inner wall of the housing; the rotor is installed on the rotating shaft; the stator and the rotor cooperate with each other to realize rotation of the rotating shaft; the rotating shaft is supported by a front bearing and a rear bearing which are installed at the two ends of the rotating shaft; the front bearing is installed inside a front bearing seat; the front bearing seat is installed at the front end of the housing; the rear bearing is installed inside a rear bearing seat; the rear bearing seat is installed at the rear end of the housing; dynamic running state parameters of the motorized spindle in an actual running process can be detected in real time by a first eddy current sensing unit of a temperature sensing unit which is arranged inside the motorized spindle; a pre-tightening force on-line regulating device which is arranged inside motorized spindle is used for implementing on-line regulation of the pre-tightening force of the spindle; and thus the motorized spindle can meet the use requirements on high speed and low temperature increment and low speed and high rigidity onthe premise of guaranteeing the machining precision.

Description

technical field [0001] The invention relates to an intelligent high-speed electric spindle integrated with multi-parameter detection. Background technique [0002] In terms of structure design and testing technology of electric spindle products, only leading foreign companies have mastered this technology, which is the secret technology for them to obtain competitive advantages in the high-end market. The design and manufacture of domestic electric spindles mostly refer to the design of foreign electric spindles, which largely restricts the technological innovation and industrial development of electric spindles in my country. Most of the existing domestic electric spindles are driven by built-in asynchronous motors through frequency conversion. The common disadvantages are: First, the existing domestic electric spindles have a single operating state parameter detection sensor, a low degree of integration, and no intelligent operating state parameters. Adjustment and optimi...
