High-precision locating mechanism for rotary chamber of carbon electrode extruder

Abstract

A high-precision locating mechanism for a rotary chamber of a carbon electrode extruder comprises a left gateway, a right gateway, the rotary chamber, locking devices and a corner detection device, wherein the left gateway is opposite to the right gateway, trunnions, bosses and grooves are arranged on the rotary chamber, the trunnions are mounted in locating holes of the left gateway and the rightgateway, an impact block is arranged on each boss, each groove is a wedge-shaped groove, impact blocks and gasket sets corresponding to the impact blocks on the bosses of the rotary chamber are arranged on the inner surface of the left gateway and the inner surface of the right gateway, locking device mounting holes are formed in the positions corresponding to the grooves of the rotary chamber, driving cylinders of the locking devices are mounted in the locking device mounting holes, plug pins are mounted on the heads of piston rods of the driving cylinders and are matched with the grooves ofthe rotary chamber, and the corner detection device is mounted on the outer side surface of the locating hole of the right gateway. The locating mechanism has the advantages that the occupied space is small, the structure is symmetrical and compact, and stress is in balance; the auxiliary locating function is achieved; detection and control precision is high; and stress concentration is small.

Description

technical field [0001] The invention belongs to the technical field of forging equipment, in particular to a carbon electrode extruder, and in particular to a positioning mechanism for a carbon electrode extruder rotating material chamber in vertical and horizontal positions. Background technique [0002] During the carbon electrode extrusion molding process of the carbon electrode extrusion machine, the rotating material chamber should rotate twice in each working cycle, from the horizontal position to the vertical position, and then from the vertical position back to the horizontal position. When the rotating material chamber is in the vertical position, it is the process of filling paste, tamping, and pre-pressing; when the rotating material chamber is in the horizontal position, the process of extrusion molding of the green body is completed. Each conversion of the position of the rotary material chamber requires accurate positioning and locking of its position. In the ...
