Live center mechanism of cabling machine cradle

Abstract

The invention discloses a live center mechanism of a cabling machine cradle. The mechanism comprises a rack, a shaft, a fixed sleeve, a moving sleeve and a positioning mechanism, the positioning mechanism is used for positioning the moving sleeve, the shaft is arranged on the rack, the moving sleeve is rotatably installed on the shaft, the fixed sleeve is disposed on the outside of the moving sleeve and fixedly connected with the rack, a bearing cap is installed at the left end of the moving sleeve, a second gland is installed at the right end of the moving sleeve, the left end of the shaft penetrates through the bearing cap, a centre is installed at the end of the shaft, the right end of the shaft is located in the moving sleeve, a through hole is disposed at the center of the second gland, an outer hexagonal screw is welded on the through hole, a first screw thread is arranged on an inner circle of the fixed sleeve, a second screw thread which is matched with the first screw thread is arranged on an outer circle of the moving sleeve, and a plurality of positioning grooves which are close to the second gland are uniformly disposed on the periphery of the moving sleeve. The live center mechanism of the cabling machine cradle has the advantages that the structure is compact, the usage and operation are convenient, and problems that loading and unloading of wire coils of existing cabling machines are required to be completed by cooperation of numerous workers, the wire coil replacement is time and effort consuming, the operation procedures are verbose, and the production efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of cable equipment, and in particular relates to a cable-forming machine for twisting three-core, four-core and five-core cables into cables, wrapping them online, and armouring them, and especially relates to the activities of the cradle of the cable-forming machine top institutions. Background technique [0002] There are five sets of top mechanisms on each cable-forming machine. The top mechanism of the existing cable-forming machine cradle uses two semi-circular rings to compress the top shaft and position the bearings. The outside is hinged, and the other side is manually locked with a pin. When changing the disk, it is necessary to manually loosen the locking pin and open the upper half of the ring. At the same time, the crane supports the empty disk. Two or more people cooperate to manually take out the top shaft and bearing, lift the empty disk, and replace it with a full disk. Manually install the...
