Automatic grinding device for strain clamp parts

Abstract

The invention belongs to the technical field of power cable clamping devices, and particularly relates to an automatic grinding device for strain clamp parts. The automatic grinding device comprises aclamping device, a rotating platform and a grinding device body; and the clamping device comprises a bracket, an air cylinder, a spring, a fixing sleeve and an upper pressing seat. According to the automatic grinding device for the strain clamp parts, working efficiency can be greatly improved, and more than 30 parts can be machined in one hour; and grinding and cleaning are conducted through corresponding dust collecting covers, grinding and cleaning are efficient and reliable, the grinding effect is good, dust flying can be avoided and dust can be timely cleaned, and production safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of power cable clamping devices, and in particular relates to an automatic grinding device for tension clamp parts. Background technique [0002] At present, there are mainly three kinds of devices for fixing and clamping the steel-reinforced aluminum stranded wire in domestic transmission line connection clamps. One is wire plugging, the contact surface is small and the plugging is not strong, and the wires are prone to heat; the other is aluminum tube hydraulic pressure. When installing, the wires at both ends are inserted into the aluminum tube, and then pressurized with a hydraulic tool, but the contact surface is small and the grip is not strong; The impact force changes the metallographic phase, the mechanical strength is reduced, and the explosion is not safe. At present, due to the special structure of the wire clip, in order to facilitate the subsequent installation of the cast wire clip, it is nec...

[0002] At present, there are mainly three kinds of devices for fixing and clamping the steel-reinforced aluminum stranded wire in domestic transmission line connection clamps. One is wire plugging, the contact surface is small and the plugging is not strong, and the wires are prone to heat; the other is aluminum tube hydraulic pressure. When installing, the wires at both ends are inserted into the aluminum tube, and then pressurized with a hydraulic tool, but the contact surface is small and the grip is not strong; The impact force changes the metallographic phase, the mechanical strength is reduced, and the explosion is not safe

At present, due to the special structure of the wire clip, in order to facilitate the subsequent installation of the cast wire clip, it is necessary to grind the connection hole on the wire clip and the surrounding of the connection hole to facilitate subsequent tapping. Traditionally, the processing of the entire position is done by workers. Directly use the lathe for processing, first fix it and then use the lathe tool for processing. Although this method is more accurate, the speed is very slow. About 10 pieces can be processed in one hour, and the main time is wasted on clamping the connecting wire clamp. Therefore it is urgent to develop a fixture that can quickly process the connecting wire clamp
