Intelligent high-speed electric spindle integrated with multi-parameter detection

Abstract

The invention discloses an intelligent high-speed electric spindle with integrated multi-parameter detection, which comprises a rotating shaft arranged in a casing, a stator fixed on the inner wall of the casing, and a rotor installed on the rotating shaft, and the stator cooperates with the rotor to realize The rotation of the rotating shaft; the rotating shaft is supported by the front bearing and the rear bearing installed at both ends; the front bearing is installed in the front bearing seat, and the front bearing seat is installed in the front end of the housing; the rear bearing is installed in the rear bearing seat, and the rear bearing The seat is installed at the rear end of the shell; the electric spindle can detect the dynamic running state parameters of the electric spindle in real time through the built-in temperature sensing unit, the first eddy current sensing unit; the built-in pre-tightening force can be adjusted online The device adjusts the pre-tightening force of the electric spindle on-line, which can meet the requirements of high speed, low temperature rise and low speed and high rigidity of the electric spindle under the premise of ensuring machining accuracy.

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...
