Disassembly tool for bowl-shaped plug

Abstract

The invention discloses a disassembly tool for a bowl-shaped plug. The disassembly tool comprises a lower clamping seat, an upper clamping seat, a pin shaft, a sliding rod and a sliding hammer; the main body structure of the lower clamping seat is a lower clamping seat semicircle body, two semicircular lower hinge seats are arranged on the bipartition plane of the lower clamping seat semicircle body, and a semicircular lower clamping seat protrusion is arranged on the semicircle face head of the lower clamping seat semicircle body; the main body structure of the upper clamping seat is an upperclamping seat semicircle body, a semicircular upper hinge seat is arranged on the bipartition plane of the upper clamping seat semicircle body, and a semicircular upper clamping seat protrusion is arranged on the semicircle face head of the upper clamping seat semicircle body; the pin shaft penetrates through lower hinge pin holes in the lower hinge seat and an upper hinge pin hole in the upper hinge seat simultaneously; the head of the sliding rod is connected with the tail end of the lower clamping seat, and the tail of the sliding rod is provide with a thrust boss; and the sliding hammer is mounted on a rod body of the sliding rod in a sleeving mode, and the sliding hammer can slide on the rod body in the front-rear direction and is limited through the thrust boss. According to the disassembly tool, the disassembly efficiency of the bowl-shaped plug is improved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine maintenance technology, in particular to a dismantling tool for a bowl plug. Background technique [0002] Bowl plug is one of the most commonly used standard parts in the field of mechanical design. Due to its simple structure, excellent sealing performance and low cost, it is often used for sealing oil passages, water chambers, process holes and other positions on internal combustion engines. When the bowl-shaped plug is used, in order to ensure good sealing performance, the connection between the bowl-shaped plug and the plugging hole is designed as an interference fit. However, due to the interference fit, the old bowl plug is difficult to disassemble when a new bowl plug needs to be replaced for maintenance. The traditional method of removing the bowl-shaped plug is: use a drill to drill a hole on the bowl-shaped plug, then use a screwdriver to insert it into the hole, and...

Problems solved by technology

[0003] The traditional method of removing the bowl-shaped plug has the following disadvantages: (1) tools such as electric drills and screwdrivers are required, which is inconvenient to operate and takes a long time; (2) the original bowl-shaped plug needs to be drilled for destructive treatment; (3) drilling The iron filings that fall during the hole have a strong impact on the cleanliness of the internal combustion engine; (4) it takes a lot of effort to take it out when prying off the bowl-shaped plug, and the labor intensity is relatively large; (5) the work efficiency is low
