Embodiment Construction

[0021] The specific embodiment of the equipment body in the double-position porcelain sleeve cutting and grinding machine of the present invention is as follows: figure 1 As shown, it includes a machine base 1, and the two ends of the machine base 1 are respectively equipped with a main shaft drive box 4 and an auxiliary tail box 9. The main shaft in the main shaft drive box 4 is driven by a cycloidal pin gear reducer driven by a motor. The belt drive spindle rotates. The first rail group 2 and the second rail group 3 arranged in parallel are respectively installed on both sides of the machine base 1. The two rail groups 2 and 3 are respectively composed of two parallel plane rails. To cutting mechanism 7,11, the cutting saw blades on the two cutting mechanisms 7,11 are arranged in parallel, and the saw blades on the two cutting mechanisms 7,11 rotate in the same direction as the main shaft in the main shaft drive box 4; A pair of grinding mechanisms 6,12 are installed, and t...

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...
