Problems solved by technology

Since this linear scanning motion device requires mechanical transmission, its motion accuracy and volume are limited
In addition, the center of mass of the mover part of this linear scanning motion device migrates during the motion, which makes it have obvious impact on the stator and the fixed bracket during high acceleration and high speed motion.
This kind of impact seriously affects the movement accuracy and the safety and stability of the device for a long time

Embodiment Construction

[0024] The small-scale non-vibration linear motion device of the present invention mainly adopts the principle of a linear motor, and uses an energized coil to be directly driven by Lorentz force in a parallel magnetic field to realize linear motion; The active block is connected with the rocker arm and drives the driven block, so that the driven block can move at the same speed, parallel and opposite direction as the active block; the driven block coincides with the center of mass of the active block with equal mass. So as to achieve the purpose of reciprocating linear motion with high speed, high precision, no vibration and impact.

[0025] figure 1 Shown is the three-dimensional structural diagram of the small-scale non-vibration linear motion device of the present invention, which includes: a shell 1, a magnetic steel 5 that produces two parallel magnetic fields in opposite directions in the magnetic steel fixing frame 3, a rectangular coil 9, A mover fixed with the recta...

Abstract

A small non-vibration line movement device includes: a shell, a rotor, two parallel magnetic fields in opposite direction set in a magnetic steel fixing frame, a square coil fixed with the rotor, two opposite sides of the coil are placed in the two parallel fields separately, said frame is fixed on the shell. Said rotor is composed of a driving block and a driven block set on two slide rails parallel to the plane of the square coil, the driving block is fixed with the square coil, the two blocks are connected with both ends of a rockerarm. This invention uses Lorentz force directly to eliminate error and driving impact brought by mechanical drive and uses dynamic balance technology to eliminate the impact to the shell due to the acceleration and high-speed movement.

Description

technical field [0001] The invention relates to a linear motion device, especially a small vibration-free linear motion device capable of ensuring high precision and no vibration in high-speed and high-acceleration reciprocating motion, and is a short-stroke linear scanning motion device. Background technique [0002] At present, known motion devices for short-stroke linear scanning usually use speed-adjustable rotating motors to convert rotary motion into linear motion through racks, rocker arms or cams. This short-stroke linear scanning motion device is widely used in ultrasonic scanning detection. Since this linear scanning motion device requires mechanical transmission, its motion accuracy and volume are limited. In addition, the center of mass of the mover part of this linear scanning motion device migrates during the motion, so that it has obvious impact on the stator and the fixed support during high acceleration and high speed motion. This kind of impact seriously ...
