Abstract

The invention provides a bowl-shaped plug dismantling tool which comprises a bowl-shaped plug tightly-sleeving assembly and a pulling-poking device assembly, wherein the bowl-shaped plug tightly-sleeving assembly comprises an expansion sleeve and an expansion rod matched with the expansion sleeve; the expansion sleeve comprises a threaded connection section and an expansion section; a run-through matching hole is formed in the shaft center of the expansion sleeve; an internal thread is formed in the matching hole at the threaded section; the end opening, adjacent to the expansion section, of the matching hole gradually shrinks; a plurality of separation grooves are axially formed in the part adjacent to the end opening of the expansion section; the end part of the expansion section is correspondingly divided into a plurality of clamping bars with stretching elasticity; a clamping cone is formed on the outer side surface of each clamping bar; the expansion rod comprises a matching section and a propping section; an external thread is formed in the periphery of the matching section; the expansion rod penetrates into the expansion sleeve; the external thread of the matching section is matched with the internal thread of the expansion sleeve; the propping section is matched into the matching hole; after the expansion rod is screwed by a preset distance, the propping section is propped against the inner sides of the clamping bars at the end opening of the expansion section to enable the clamping bars to be propped to unfold. The bowl-shaped plug dismantling tool is simple in structure and can ensure that a bowl-shaped plug is conveniently dismantled.

Description

technical field [0001] The invention relates to the technical field of assembly of mechanical parts, in particular to a tool for disassembling an assembled bowl stopper. Background technique [0002] In the process of manufacturing or testing mechanical parts, bowl plugs are often used. Bowl plugs are bowl-shaped parts used to seal the through holes of parts. For example, when an automobile engine block is being tested for air tightness or leak testing, a bowl plug is usually used to block the holes on the block, and only the detection channel is reserved for injecting gas or oil. After testing, remove the bowl stopper. Currently, most of the tools used to disassemble the bowl plug are clamps, etc. It is difficult to remove the bowl plug smoothly, which takes a long time. If the bowl plug is disassembled and then re-inserted, if the bowl plug cannot be pulled out smoothly for a short time, the production efficiency will be greatly affected. Moreover, when the traditional ...
