Abstract

The invention provides a single-slide-carriage twin-trawling linear motor test platform, belongs to the technical field of linear motor tests, and solves the problems of large stagnant force during start and low loading response speed of a double-slide-carriage twin-trawling linear motor test platform. A test slide carriage supports a loading connecting plate through a transmission mechanism, so that the loading connecting plate is suspended on a base, the support and transmission relation between the test slide carriage and the loading connecting plate enables the loading connecting plate tobe made from a non-marble material, and when a tested linear motor is loaded, the test slide carriage drives active cells of two iron-core-free linear motors used for loading and connected with the loading connecting plate to move under the action of output force of an active cell of the tested linear motor, or enables the loading connecting plate to push the test slide carriage and the active cell of the tested linear motor connected with the test slide carriage under the action of the driving force of the active cells of the two iron-core-free linear motors used for loading, thereby reducingthe stagnant force during start of the test platform. The single-slide-carriage twin-trawling linear motor test platform mainly tests linear motors.

Description

technical field [0001] The invention relates to a novel single-slide tow-type linear motor testing platform, which belongs to the technical field of linear motor testing. Background technique [0002] In the field of modern processing industry, linear motors are widely used in factory automation, reciprocating servo systems, conveying systems, transportation, etc., especially in CNC machine tools. The traditional CNC machine tool adopts the driving method of "rotary motor + ball screw", which has many unfavorable factors, including the length limitation of the screw itself, pitch cycle error, mechanical backlash during feeding, and the gap between the coupling part and the screw. There is friction, coupling inertia, etc. between them, which limit the working efficiency and machining accuracy of the machine tool. Compared with the traditional "rotary motor + ball screw" driving method, the direct drive avoids possible errors in the intermediate transmission link, has compact...
