Abstract
The utility model belongs to the technical field of hand tool, concretely relates to cotter pipe extracting tool. The end of the ear of a certain type of nose landing gear is provided with a pin pipe connected with a machine body, and the matching surface of the outer wall of the pin pipe is coated with a layer of 307 glue, so that the pulling-out force is very large when the pin pipe is detached, a screwdriver penetrates through a section of small hole of the pin pipe, and then the screwdriver is hammered to separate the pin pipe from the landing gear, but parts are easy to be knocked. The utility model provides a specialized tool pulls out the cotter pipe through the axial tension who utilizes the rotatory production of threaded spindle, can easily pull down the nut to dismantle the cotter pipe better.
Description
Technical Field
The utility model belongs to the technical field of hand tool, concretely relates to cotter pipe extracting tool.
Background
The end of the ear of a certain type of nose landing gear is provided with a pin pipe connected with a machine body, and the matching surface of the outer wall of the pin pipe is coated with a layer of 307 glue, so that the pulling-out force is very large when the pin pipe is detached, a screwdriver penetrates through a section of small hole of the pin pipe, and then the screwdriver is hammered to separate the pin pipe from the landing gear, but parts are easy to be knocked.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a specialized tool is designed to dismantle the round pin pipe better.
The utility model discloses a pin tube dismounting tool, which comprises a threaded shaft, a pin shaft, a sleeve, a radial thrust ball bearing, a wrench and a nut, wherein the threaded shaft is provided with a through hole at one end; one end of the sleeve is open, the other end of the sleeve is provided with a hole which can be inserted into the threaded shaft, and the pipe wall of the sleeve is provided with opposite grooves; the pin shaft is connected with the groove of the sleeve, the split hole on the pin pipe and the through hole of the threaded shaft through insertion; the nut is in threaded connection with the threaded shaft and tightly presses the radial thrust ball bearing on the outer side of the end part of the sleeve; the wrench is rotated to drive the nut, and the pin pipe is pulled out.
The beneficial effects of the utility model are that pull out the cotter pipe through the axial tension who utilizes the rotatory production of threaded shaft, can easily pull down the nut.
