Abstract
The invention provides a rotating wire clamp for a spacer of overhead transmission lines, which is provided with a wire clamp supporting body and a rotating wire clamp body. The wire clamp supporting body is fixedly connected with a spacer body. The rotating wire clamp body comprises a semicircular arc-shaped first wire clamp head and a semicircular arc-shaped second wire clamp head, two circular arc-shaped first rotating rods and two linear second rotating rods, wherein the second rotating rods perform circular motion by using self symmetric centers as axes; and a four-rod mechanism with a fixed motion track realizes the wire clamping of the clamp head of the wire clamp and free rotation is realized by using a wire center as an axis. In the design of the rotating wire clamp, the traditional design concept that the rotating clamp head rotate by sliding is abandoned, so the problem that the sliding type rotation of the clamp head is likely to cause discontinuous and unsmooth rotation of the clamp head is solved.

Research work is mainly set about by following step:
(1) at first determines revolution chuck basic structure form.
(2) determine and the supporting fixed rack basic structure form of revolution chuck.
(3) determine that chuck wears pin basic structure form.
(4) three-dimensional software design revolution chuck.
(5) virtual prototype and finite element software carry out motion analysis and load to the revolution chuck and calculate final optimization pass and go out product.
At first want structure model selection, three dimensional design arrives the such cyclic process of three dimensional design again and finally determines to optimize product to motion analysis and machine finite element analysis then.
The invention has the beneficial effects as follows: the present invention utilizes four-bar mechanism principle realization swiveling head Clamping Center to realize freely rotating for axle.This mechanism structure is simple, the rotation flexibility and reliability.
