Abstract

The invention discloses a compact three-dimensional motion mechanism. The compact three-dimensional motion mechanism comprises a Z-axis motion mechanism, a connecting fixed plate, an X-axis motion mechanism, a horizontal moving plate, a synchronous follower plate and a Y-axis motion mechanism, wherein the connecting fixed plate is connected with the output end of the Z-axis motion mechanism, the X-axis motion mechanism is arranged on the connecting fixed plate, the horizontal moving plate is connected with the output end of the X-axis motion mechanism, the synchronous follower plate can be connected with the bottom surface of the horizontal moving plate in a Y-direction movement manner, the Y-axis motion mechanism is arranged on the surface of the synchronous follower plate, the output endof the Y-axis motion mechanism is connected with the horizontal moving plate, and the surface of the synchronous follower plate is used for installing loads. Therefore, the Z-axis motion mechanism isused for driving the connecting fixed plate, the X-axis motion mechanism is used for driving the horizontal moving plate, the Y-axis motion mechanism is used for driving the synchronous follower plate, three-dimensional space motion of the loads can be realized smoothly, and meanwhile a non-laminated installation structure (a horizontal distribution structure) is formed. Therefore, compared witha laminated installation structure in the prior art, the overall height of the compact three-dimensional motion mechanism can be significantly reduced, and space occupation is reduced.

Description

technical field [0001] The invention relates to the technical field of motion mechanisms, in particular to a compact three-dimensional motion mechanism. Background technique [0002] A three-dimensional motion mechanism is a commonly used motion mechanism or drive mechanism, which can drive a load or a workpiece to perform three-dimensional motion in space. Generally, a three-dimensional motion mechanism mainly includes three-axis motion degrees of freedom of X-Y-Z, that is, two-direction plane motion in the horizontal plane and vertical lifting motion. [0003] At present, three-dimensional motion mechanisms are often assembled by stacking three single-axis motion mechanisms, such as installing a Z-axis motion mechanism at the bottom, stacking an X-axis motion mechanism in the middle, and stacking a Y-axis motion mechanism at the top. Although the structure of the three-dimensional motion mechanism in the prior art can conveniently realize the three-dimensional motion driv...

Problems solved by technology

Although the structure of the three-dimensional motion mechanism in the prior art can conveniently realize the three-dimensional motion driving of the load, the overall structure of the three-dimensional motion mechanism is in a vertically stacked shape. Occupies a lot, and there are many connecting parts between the two motion mechanisms, resulting in a large volume and weight
