Problems solved by technology

[0003] At present, the main methods of drawing carbon lines are manual drawing and semi-automatic drawing. The diameter of the ceramic tube used in the gas discharge tube is small, and the accuracy and uniformity of the manual drawing process will be poor. In semi-automatic line drawing, because the carbon lead is thin and easy to break, the clamped carbon lead is relatively short, resulting in frequent replacement of carbon lead and increased manual labor for workers; while the carbon lead clamped by the clamp cannot Full utilization, low utilization rate of carbon and lead, increased production cost

Abstract

The invention provides a high-precision porcelain tube automatic line drawing device. The device comprises an up-down guide rail, an up-down slide block, a mounting plate, a carbon lead feed motor, a lead screw, a nut, a fixing plate, a pencil lead and a pencil stub, wherein the upper part of the up-down guide rail is fixedly connected with the mounting plate; the mounting plate is provided with the motor; the motor is connected with the lead screw through a coupling; the up-down slide block is arranged on the up-down guide rail and is fixedly connected with the fixing plate; the fixing plate is provided with a first through hole and a third through hole; the pencil lead is arranged at the first through hole; the lower end of the pencil lead is connected with the pencil stub; the lead screw is provided with the nut; the nut is arranged on the fixing plate through the third through hole. According to the high-precision porcelain tube automatic line drawing device, by arranging the motor, the coupling, the lead screw, the fixing plate, the pencil lead, the pencil stub and the like, on-time automatic quantitative feed of carbon lead is realized, the feed is adjustable, the length and the number of drawn carbon lines are adjustable, and the precision and the accuracy are high.

Description

Technical field [0001] The invention belongs to the field of gas discharge tube processing equipment, and particularly relates to a high-precision porcelain tube automatic line drawing device. Background technique [0002] As a switching device, the ceramic gas tube is the most widely used in lightning protection equipment. Whether it is AC / DC power supply or lightning protection of various signal circuits, it can discharge lightning current into the earth. It consists of two electrodes encapsulated in a ceramic tube separated by a certain distance. Its main characteristics are: large discharge current, small inter-electrode capacitance (≤3pF), high insulation resistance (≥109Ω), large breakdown voltage dispersion (±20%), and slow response speed (the fastest is 0.1~0.2 μs). According to the number of electrodes, there are two types: two-pole discharge tube and three-pole discharge tube (equivalent to two two-pole discharge tubes in series). Its shape is cylindrical, and it has...
