Drive feeding mechanism of dual-linear motor

Abstract

The invention relates to a drive feeding mechanism of a dual-linear motor, which forms a self-adaptive rotation angle function of a crossbeam by the combination of one linear displacement and two hinging points between the crossbeam and a sliding base on two linear guideways in the X direction. The drive feeding mechanism mainly solves the technical problem that, the mechanical structure has interference on the testing motion and the like when the dual-linear drive feeding mechanism of the motor of the prior art is tested. The drive feeding mechanism has the function of self-adaptive rotationangle and is applicable to the detection requirement of the high-speed performance of the linear motor, such as the detections on acceleration and deceleration performance, static and dynamic high-speed response performance, positioning precision, repeated positioning precision, synchronous control precision and temperature field distribution of the dual-linear motor and the like.

Description

technical field [0001] The invention relates to a double linear motor high-speed drive feed mechanism, in particular to a double linear motor drive feed mechanism with a double articulated gantry frame combined structure. Background technique [0002] At present, high-speed machining technology in the world has become one of the main technologies that have developed rapidly in recent years. Linear motors have begun to appear in machining centers as high-speed feed systems. Since the direct drive feed system has advantages and potentials that cannot be compared with the traditional feed system, it has once again attracted the attention of various countries. As an electromechanical system, the linear motor-based drive feed system simplifies the mechanical structure and complicates the electrical control, which is in line with the development trend of modern electromechanical technology. On the one hand, domestic research on the application of linear motors, especially the res...
