Abstract

The invention discloses an air passage ring cutting tool for a pantograph pan. The air passage ring cutting tool for the pantograph pan comprises a support (1), a cutting control rod (3), a dial indicator (7) and a transmission member (4). A cutting blade (2) is rotatably arranged on the support (1). The cutting control rod (3) is arranged on the support (1) in a vertical moving mode in the height direction of the support (1), and an air passage clamping mechanism (5) is arranged at one end, facing the cutting blade (2), of the cutting control rod (3) to form an air passage ring cutting chamber (6) with the cutting blade (2). The dial indicator (7) is fixedly arranged on the support (1) and is provided with a measuring rod (8). One end of transmission member (4) is connected with the cutting control rod (3), and the other end of the transmission member (4) is matched with the measuring rod (8), so that the displacement amount of the cutting control rod (3) is reflected in reading numbers of the dial indicator (7) through the measuring rod (8). Therefore, precise control of the blade feeding amount of the air passage cutting bade is achieved, uniformity of the depth of all thin grooves in a copper pipe of the air channel is ensured, and the safe operation of a haulage motor is ensured.

Description

technical field [0001] The invention relates to the field of processing the pantograph slide air channel of an electric locomotive, in particular to a pantograph slide air channel circumcision tool for cutting fine grooves on the outer surface of the pantograph slide air channel used on the electric locomotive . Background technique [0002] The pantograph slide is a key component for the safe operation of electric locomotives. During the operation of the locomotive, the pantograph slide plate is in contact with the catenary and has a high-speed relative motion, and is constantly subjected to high-speed impact and frequent vibration of the catenary. In order to ensure safe operation, the electric locomotive adopts an automatic lowering system of the pantograph. The basic principle is to set an air passage (usually copper pipe) in the slide plate, and the air source system supplies compressed air to it from the pantograph. . When the slide plate breaks, the air passage is ...
