High-speed point-to-point movement executing mechanism

Abstract

The invention relates to a point-to-point motion actuating mechanism in an automatic motion system, in particular to a point-to-point motion mechanism which can move rapidly between any two points and carry out high-precision point location. By making use of the interpolation motion of a straight line motion mechanism and a slider crank mechanism, the invention realizes the point-to-point motion; simultaneously, as original motive parts are fixed on a system frame and do not take part in the motions, the weight of motion parts of the system is reduced; in addition, the mechanism with the interpolation motion has a longer stroke, which causes the point-to-point motion actuating mechanism to work when the altitude difference is big. Furthermore, the motion positioning conditions of operating points are timely fed back to a control system by a motion feedback device, which can realize the rapid and precise point-to-point motions between any two points.

Description

technical field [0001] The invention relates to a point-to-point motion actuator in an automatic motion system, in particular to a point-to-point motion mechanism capable of fast movement between any two points and high-precision point positioning. Background technique [0002] In automated motion systems, point-to-point motion is often involved. In the prior art, the principles of the point-to-point motion actuators used in industry are basically similar, but the implementation methods are different. One is to use a rotating arm or a crank slider mechanism to realize the movement between two points. The transmission device using this scheme is relatively simple, but it takes up a lot of space, has a large volume, slow running speed, and low work efficiency. Accuracy has a great influence on precise positioning; the other is direct transmission by screw or synchronous belt. In the point-to-point motion realized by the above two methods, because the original moving part of ...

Problems solved by technology

One is to use a rotating arm or a crank slider mechanism to realize the movement between two points. The transmission device using this scheme is relatively simple, but it takes up a lot of space, has a large volume, slow running speed, and low work efficiency. Accuracy has a great influence on precise positioning; the other is direct drive by screw or synchronous belt

In the point-to-point motion realized by the above two methods, because the original moving part of the system participates in the movement, and the original moving part usually has a relatively large mass, it will seriously affect the running speed and accuracy of the entire motion actuator, and then seriously affect the work of the entire system efficiency

Moreover, the point-to-point movement achieved by the above method requires that the two points must be at the same height or the height difference should not be too large, otherwise it cannot be realized
