Pressing type multi-class central curve track control mechanism

Abstract

The invention discloses a pressing type multi-class cnetral curve track control mechanism. The control mechanism comprises a centering disc frame, a shaft sleeve outer cover, an inner shaft pipe, a screw pipe with a lock, a radial rotating rod, a planet shaft pipe, a winding wheel disc, a planet rotating rod and winding wheel sets. The inner shaft pipe is rotationally mounted in the center of thecentering disc frame through the shaft pipe outer cover; the screw tube with the lock is inserted into the centering disc frame in a sliding manner; the inner shaft pipe and the radial rotating rod are driven to rotate, the shaft sleeve outer cover is provided with a first winding groove, the winding wheel disc is sequentially provided with a second winding groove and a third winding groove from top to bottom, the winding wheel sets are arranged on the radial rotating rod, and a thread rope wound on the first winding groove is connected to the second winding groove or the third winding groovein a wound mode after passing through the winding wheel sets. According to the control mechanism, various specific central curve tracks such as variable-parameter circles, ellipses, hypocycloids, epicycloids, spirals and the like can be more accurately realized, the tracks of drawing, cutting, spraying or 3D printing cylindrical surface alignment lines are more accurately ensured to accord with corresponding curves, and the design requirements are met.

Description

technical field [0001] The invention relates to a control mechanism for pressing multi-category centered curve tracks. Background technique [0002] In the existing technology, in the process of some product design and trial production, it is necessary to complete the effects of drawing, cutting and spraying on the flat material according to the centered curve of specific parameters. Lines are the most widely used, and objects constructed from such curves play a key role in our production and life. However, there is currently a lack of devices capable of drawing, cutting and spraying a variety of deliberate curves in the processing process. Usually, only some curve gauges or curve plates are assisted. These devices are often only suitable for specific types of curves or a small number of two or three types of curves. And it is not necessarily applicable to cutting, spraying, etc., or applied to other executive components such as cutting knives and nozzles will cause increas...

Problems solved by technology

[0003] The object of the present invention is to provide a control mechanism for pressing multi-category centered curve tracks, to solve the problem that most of the centered curve track control devices in the prior art are curve gauges or curved plates, and there are fewer types of centered curves applicable, and for cutting, The problem of insufficient accuracy of the curve due to differences in the execution components in spraying or 3D printing effects
