Abstract

The invention provides a locating tool for pressing a locomotive silicon rectifier tube. A backing plate is fixedly arranged on a worktable. A locating plate is shelved on the backing plate. The center of the locating plate and the center line of a pressure head are collinear. Locating holes are formed in the locating plate, are distributed in the circumferential direction, and take the center of the locating plate as the center of a circle. Support sleeves are arranged on the locating holes, and comprise support sleeve upper parts and support sleeve lower parts. The external diameters of the support sleeve upper parts are larger than those of the support sleeve lower parts. Flanges are arranged at the support sleeve upper parts. Blind holes of which the openings face upwards are formed in the support sleeve upper parts. Supporting feet of the locomotive silicon rectifier tube are placed in the blind holes of the support sleeves. Grooves are formed in the inner walls of the blind holes. Clamping strips are arranged in the grooves. The external diameters of the support sleeve lower parts are smaller than the internal diameters of the locating holes. The locating tool is high in pressing efficiency, small in error, convenient to operate, and high in generality.

Description

technical field [0001] The invention relates to a tool for positioning during pressing, in particular to a positioning tool for pressing silicon rectifier diodes of locomotives, and belongs to the technical field of mechanical processing. Background technique [0002] The rectifier is an indispensable part of the generator. It has two main functions: first, it converts the three-phase alternating current generated by the stator coil of the locomotive alternator into direct current after being rectified by a diode, and then supplied to the load after filtering, or to the inverter. Inverter; second, to provide charging voltage to the battery. Therefore, it acts as a charger at the same time, charging the locomotive battery and supplying power to other electrical appliances of the locomotive. High-voltage silicon stacks are often used in high-voltage rectifier devices, which are composed of multiple rectifier cores in series. The reverse withstand voltage is determined by the ...
