Abstract

The invention discloses a high-speed high-precision servo linear motor sliding table which comprises a sliding table base, a lower sliding table is slidably connected with the sliding table base, and an upper sliding table is slidably connected to the lower sliding table; the upper sliding table and the lower sliding table respectively slide along the directions of X-axis and Y-axis which form an angle of 90 DEG, and the sliding table base, the upper sliding table and the lower sliding table are cast from cast iron. The invention has simple structure, wide speed range, good speed characteristics, high positioning precision, low noise and less wear, and can completely satisfy the requirements of numerical control machine development; compared with the traditional sliding table, the servo linear motor sliding table is more economical and practical; and the servo linear motor sliding table can be applied to high-precision feeding mechanisms of numerical control turning machines, and can also be applied to precision sliding tables of numerically controlled milling machines and processing centers.

Description

technical field [0001] The invention relates to a servo motor slide table. Background technique [0002] CNC machine tools are developing in the direction of precision, high speed, compound, intelligence and environmental protection. Precision and high-speed machining put forward higher requirements for transmission and its control, higher dynamic characteristics and control accuracy, higher feed speed and acceleration, lower vibration noise and smaller wear. The crux of the problem is that the traditional transmission chain needs to go through intermediate transmission links such as gears, worm gear pairs, belts, screw pairs, couplings, clutches, etc. from the motor as the power source to the working parts, and large rotations are generated in these links. Inertia, elastic deformation, backlash, motion hysteresis, friction, vibration, noise and wear. Although the transmission performance has been improved through continuous improvement in these aspects, the problem is dif...
