Abstract

The invention relates to a micrometric displacement regulation device, in particular to a combined type transmission variable-angle micrometric displacement regulation device comprising a fixed base, a worm gear, a worm, a screw rod, a push rod, joint bearings and a regulation and fastening part. By regulating a handle at one end of the worm, the worm and the worm gear are engaged to realize primary transmission. The center of the worm gear provides a thread hole, and secondary transmission is realized by a thread pair and the screw rod. The rotary motion of the screw rod is restricted by a flat key, and the push rod only can be pushed along a linear direction. Both ends of the push rod are respectively arranged with the joint bearing, and the push rod pushes a working platform to realizeangle rotation or linear displacement motion. The invention also can adopt a motor for control. A worm shaft is connected with a motor shaft by a shaft coupling, and the motor is connected with a computer by a driving control system to realize control. A displacement sensor can be arranged on the screw rod and used for measuring the displacement quantity of the screw rod at real time. The entire control system can adopt an open-loop or closed-loop system. The invention has compact layout and simple kinematic chain and ensures the regulation accuracy. The invention can be used by combining a single set or a plurality of sets so as to meet the regulation requirement of different angles or displacements of the working platform. The invention is especially suitable for an occasion for regulating the displacement or angle with moderate accuracy in a micron magnitude or an arc second magnitude.

Description

technical field [0001] The invention relates to a micro-displacement adjustment device, in particular to a combined transmission variable-angle micro-displacement adjustment device. Background technique [0002] Precision displacement adjustment has a wide range of applications in precision machinery manufacturing, micro-electromechanical systems, optical component adjustment, robotics, and other fields. In the micro-displacement adjustment with medium precision (micron level), the mechanical micro-displacement adjustment device is widely used, and has the advantages of simple structure, convenient operation and control, etc. Common mechanical micro-displacement adjustment methods include: (1) differential screw drive; (2) wedge or cam mechanism; (3) multi-stage precision gear transmission; (4) lever mechanism; (5) elastic mechanism, etc. The above mechanisms meet the requirements of different occasions, especially the adjustment of micron-scale resolution, but a single adj...
