Apparatus and method for processing the shape of an oval porcelain insulator

Abstract

The invention discloses an elliptical porcelain insulator shape processing device and a processing method thereof. The elliptical porcelain insulator shape processing device comprises a rotation mechanism and a porcelain insulator shape processing mechanism; the porcelain insulator shape processing mechanism comprises a rack, a positioning plate arranged on the rack, a lifting device capable of moving upwards and downwards along the rack and an expansion device capable of moving back and forth horizontally along the lifting device; a fettling knife is arranged on one end of the expansion device; the expansion device is also provided with a positioning rod which cooperates with the positioning plate; the expansion device can drive the fettling knife and the positioning rod to move back and forth horizontally; the lifting device and the expansion device control the positioning rod on the expansion device to cooperate with the positioning plate, so that the fettling knife on the end of the expansion device processes the shape of the insulator earthen brick along the positioning plate. The elliptical porcelain insulator shape processing device reduces production difficulty of the elliptical porcelain insulator, and increases product percent of pass.

Description

technical field [0001] The invention relates to a manufacturing mechanism and a manufacturing method of a ceramic device, in particular to a device for processing the shape of an elliptical porcelain insulator and a processing method thereof. Background technique [0002] At present, there are various types of electric locomotives in various countries in the world, but the main circuit of the top power supply of electric locomotives uses metal conductive rods and supporting insulators for high-voltage power transmission. Its power supply process is: the 19kV ~ 29kV high voltage collected by the pantograph slide is transmitted from the pantograph frame to the metal conductive rod, and then fed to the power load of the electric locomotive. Roof pantographs and conductive rods are all bare non-insulated metal rods. Tens of thousands of volts of high voltage are insulated from the ground, and they are all supported by insulators. This is the unified structural model of all count...

Problems solved by technology

[0013] Although the above-mentioned patent document discloses a device for processing line post insulators, it still requires a manual hand-held tool (that is, a knife bar with a trimming umbrella knife) to move along the track of the template to process the insulator. This will still take time and effort, and increase the processing cost; during the processing, if the worker does not control the strength, the hand-held tool will be damaged, which will further increase the processing cost and affect the processing efficiency; During the movement of the tool along the track of the template, deviations will occur, which will affect the processing accuracy and reduce the processing quality of the product
