Abstract

The invention discloses a high-precision lead screw adjusting structure which is characterized in that a driving part comprises a first-stage lead screw adjusting assembly and a second-stage lead screw adjusting assembly which are driven by a first-stage servo motor and a second-stage servo motor correspondingly; the first-stage lead screw adjusting assembly and the second-stage lead screw adjusting assembly are provided with a first-stage displacement sensor and a second-stage displacement sensor correspondingly; a control part comprises a servo driver, a D / A converter, a signal input panel, a transmitter, an A / D converter and a difference calculator; the difference calculator is electrically connected with the signal input panel; and the signal input panel is provided with a mode selection and operation module and a deviation value display screen. By arranging the two-stage lead screw adjusting structure, coarse adjustment and fine adjustment of displacement can be separately processed; by collecting actual displacement data of the two stages of lead screw adjusting structures, comparing the actual displacement data with input displacement and driving switching of different modes, the requirements in the different modes can be met, the high-precision adjusting standard can be met, intelligence is higher, and the adjusting effect is better.

Description

technical field [0001] The invention relates to the technical field of automatic linear track operation adjustment, and more specifically relates to a high-precision screw adjustment structure. Background technique [0002] The screw nut mechanism is also called the screw transmission mechanism. It is mainly used to convert rotary motion to linear motion or convert linear motion to rotary motion. There are those that mainly transmit energy, such as screw presses, jacks, etc.; there are also those that mainly transmit motion, such as the feed screw of the machine tool workbench; there are also screw transmission mechanisms that adjust the relative positions between parts, etc. [0003] When converting rotary motion into linear motion, although the ordinary screw nut mechanism can be realized, it is not easy to meet the use requirements in terms of operating accuracy. With the increasing requirements of automation development, the mechanical motion accuracy and different appl...
