Cutting mill for two-position porcelain shell

Abstract

The invention discloses a cutting mill for a two-position porcelain shell, which is characterized in that cutting mechanisms and grinding mechanisms arranged on a base are alternately arranged in pairs, and a driving mechanism comprises a main-spindle driving box and a corresponding auxiliary tail box which are respectively arranged at the two ends of the base; the auxiliary tail box is provided with a drive mechanism for driving the auxiliary tail box to move along the length direction of the base; the main-spindle driving box and the auxiliary tail box are respectively equipped with a driving connector, and the two driving connectors are arranged over against each other; the driving connectors of the main-spindle driving box and the auxiliary tail box are respectively in transmission connection with a central spindle which is used for coaxially being sleeved on the inside of an inner hole of a porcelain shell; and tensioning mechanisms which are used for being in jacking fit with the internal wall of the porcelain shell are uniformly arranged on the peripheral surface of the central spindle and around the circumference of the central spindle. The cutting mill for two-position porcelain shells disclosed by the invention has the advantages that through arranging the cutting mechanisms and the grinding mechanisms in pairs and carrying out cutting and grinding on the end faces of the two ends of the porcelain shell, the parallelisms of the end faces of the two ends of the porcelain shell are effectively guaranteed, the processing cost of the porcelain shell is reduced, and the processing efficiency of the porcelain shell and the quality of the finished porcelain shell product are improved.

Description

technical field [0001] The invention belongs to the field of electric porcelain equipment production, and specifically relates to a cutting and grinding machine for producing large-scale porcelain sleeves used in high-voltage and ultra-high-voltage power transmission and distribution equipment. Background technique [0002] my country is currently vigorously developing UHV power transmission and distribution projects, which require the use of large-scale porcelain bushings for UHV power transmission and distribution of one million volts. Power distribution equipment has high requirements on the parallelism of the two end faces of this large porcelain bushing. The existing production technology is to process this large-scale porcelain sleeve in sections, that is, when making this large-scale porcelain sleeve, first divide the porcelain sleeve into several sections for extrusion, blank making, and firing to shape, and then each Cut and grind the two end faces of each segmented...
