Problems solved by technology

[0003] The flanges of high-voltage transformers in the prior art generally have poor concentricity, which leads to poor sealing effects. The specific reason is that the machine tool used for processing high-voltage transformer flanges has poor stability, and the axial direction is not stable enough during rotational processing. And the noise is very large, which greatly affects the work of the staff, and there is a certain error, which leads to poor concentricity of the flange of the high-voltage transformer and poor sealing effect

Abstract

The invention provides a machine tool for machining a high-voltage transformer flange. The machine tool comprises a workbench. First sliding rails, second sliding rails, a rotary motor and a telescopic air cylinder are arranged on the workbench. A flange fixing disc is arranged on the rotary motor. A tool mounting block moves along the first sliding rails under the action of the telescopic air cylinder to machine the flange. A baffle moves along the second sliding rails under the action of electric sliding blocks. Guide blocks are arranged on the flange fixing disc. The machine tool is simple in structure and reasonable in design; the mounting stability of the flange to be machined is effectively guaranteed; the axial stability of rotating of the flange is ensured; the machining effect of flange machining is guaranteed; the flange machining efficiency is improved; and therefore the quality and yield of the high-voltage transformer flange are improved, and the overall quality of a high-voltage transformer shell is ensured. Meanwhile, novel lubricating grease is developed, the good effects of lubrication, noise reduction and rust prevention are achieved, the kinetic energy losses of the machine tool are reduced, the rotating stability of the flange fixing disc is guaranteed, and the service life of the machine tool is also prolonged.

Description

technical field [0001] The invention relates to the production of shells of high-voltage transformers, in particular to a machine tool for processing flanges of high-voltage transformers. Background technique [0002] High-voltage transformers are transformers suitable for converting large voltages into small voltages or large currents into small currents in 1kv to 220kv power systems for easy measurement, protection, and use. They are mainly used in AC circuits to monitor the operation of electrical equipment and For the control system, there is a flange on the shell of the high-voltage transformer, which acts as a seal. [0003] The flanges of high-voltage transformers in the prior art generally have poor concentricity, which leads to poor sealing effects. The specific reason is that the machine tool used for processing high-voltage transformer flanges has poor stability, and the axial direction is not stable enough during rotational processing. And the noise is very larg...
