Abstract

The invention discloses a self-adaptive floating mechanism, and relates to the technical field of positioning mechanisms. The self-adaptive floating mechanism is characterized in that a driving structure sliding table fixing base and a robot sliding table fixing base sleeves the two ends of a connecting rod respectively, and the two sides of the robot sliding table fixing base are sequentially andsymmetrically provided with a spring limiting sleeve, a rectangular spring and a second locking nut block; the second locking nut block is fastened and fixed with the connecting rod, the supporting sleeve is arranged on one side, close to the driving structure sliding table fixing base, of the robot sliding table fixing base and is connected to the robot sliding table fixing base; and the drivingstructure sliding table fixing base and the robot sliding table fixing base are fixedly connected to a driving mechanism sliding table and a robot sliding table respectively. According to the self-adaptive floating mechanism, a floating mechanism is arranged between a servo driving sliding table and a heavy-load sliding table, the floating mechanism is arranged between the servo driving sliding table and the heavy-load sliding table, the servo driving sliding table and the heavy-load sliding table are elastically connected in a certain floating range, the positioning error of a driving mechanism and the manufacturing error of a transmission mechanism are compensated, and the overall positioning precision of the system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of positioning mechanisms, in particular to a floating mechanism for positioning a heavy-duty sliding platform. Background technique [0002] The heavy-duty slide table is a kind of machinery that realizes the feed movement. At present, the long-stroke horizontal movement of the heavy-duty sliding table requires high-precision positioning, which is generally realized by servo drive. In actual production, in order to meet the requirements of production efficiency, the moving speed of the heavy-duty sliding table is relatively high. At the same time, because it involves the grasping of workpieces, its positioning needs to meet the overall positioning requirements of the system. Although the traditional servo mechanism can guarantee a certain position accuracy, it is difficult to guarantee its positioning accuracy due to the manufacturing error of the long stroke, the positioning error of the drive mechanism a...
