Overhanging type cable winding mechanism and method applied to reciprocating type rotary table

Abstract

The invention discloses an overhanging type cable winding mechanism and method applied to a reciprocating type rotary table, and belongs to the technical field of mechanical transmission. The reciprocating type rotary table comprises a rotary table fixing part and a rotary table rotating part, wherein the rotary table rotating part is rotationally installed on the rotary table fixing part. The winding mechanism comprises: a central sleeve, arranged on the rotary table rotating part; and a suspension bracket, rotatably mounted around a rotating shaft, wherein the axis of the rotating shaft is parallel to the axis of the central sleeve and is not collinear with the axis of the central sleeve; and the suspension bracket is provided with a reel, and the reel and the center sleeve jointly form a cable winding path. Through mutual cooperation of the central sleeve and the reel, when the rotary table rotates, torsion deformation of the cable can be reduced through torsion of the cable and rotation of the reel, the cable winding and protecting functions with the limit rotating angle range not smaller than + / -360 degrees are achieved, and the whole winding mechanism is simple in structure, low in manufacturing cost, reliable in use, convenient to maintain, high in environmental adaptability and high in universality.

Problems solved by technology

[0003] Limited by the technical level, it is impossible to realize the full-frequency, low-loss continuous transmission of multiple radio frequency, electrical, optical and other signals during the rotation of the turntable through devices such as confluence rings and coaxial rotary joints. Therefore, this type of turntable can only use reciprocating The turntable structure controls its rotation angle within a certain range, and realizes the full-frequency, low-loss continuous transmission of multiple radio frequency, electrical, optical and other signals through cables

[0004] However, in order to achieve full airspace coverage of the electromagnetic space, the azimuth limit rotation angle range of the turntable is often greater than 360°, and the cable will be coiled during the rotation of the turntable. Therefore, it is generally necessary to set up a cable winding mechanism for the reciprocating turntable to provide reliable protection for the cables.

[0005] The mainstream technology adopted in the prior art is: first, use flexible parts such as steel cables to pull the axially arranged multi-layer winding plate, and drive the cable fixed on the winding plate to rotate around the center of rotation to solve the problem of cable winding , but it has the problems of large axial size, complex structure, and inconvenient cable installation and maintenance; the second is to realize the winding of the cable through elastic elements and external force pulling, but it is not suitable for the cable winding protection requirements of the turntable
