Problems solved by technology

[0007] However, there are defects in the above several installation methods: the first installation method is time-consuming, labor-intensive, and has low assembly efficiency, which is not suitable for mass production and does not meet the requirements of modern production; the second installation method is costly and expensive. Low assembly efficiency; the third installation method is more suitable for interference installation of cylindrical parts on small components, but not suitable for interference installation of cylindrical parts on large components

Abstract

The invention provides an interference assembling tool for a cylindrical part. The interference assembling tool for the cylindrical part comprises a jack. The jack comprises a cylinder body and a telescopic piston rod. A through hole axially penetrating through the cylinder body and the piston rod is formed in the jack. A guide rod is arranged in the through hole in a penetrating mode. A left blocking piece and a right blocking piece are installed at the two ends of the guide rod respectively. The jack is located between the left blocking piece and the right blocking piece. The cylindrical part is assembled in a component under the pushing force of the piston rod of the jack, and therefore interference assembling of the cylindrical part is achieved, the whole assembling process is conveniently and fast conducted, time-saving and labor-saving, one or two cylindrical parts can also be assembled once, and assembling efficiency is improved. The interference assembling tool for the cylindrical part is suitable for interference assembling of cylindrical parts of all kinds of sizes, and is wider in applicable range.

Description

Technical field [0001] The invention relates to an auxiliary installation equipment for mechanical parts, in particular to an interference assembly tool for cylindrical parts. Background technique [0002] In the production practice in the field of mechanical processing, the following situations are often encountered: figure 1 As shown, a certain component 6 is provided with a hole 61, one end or both ends of the hole 61 is provided with a stepped hole 62 with a diameter larger than that of the hole 61, and a cylindrical shape such as a sleeve or a shaft sleeve needs to be installed in the stepped hole 62 Part 7 and the cylindrical part 7 and the stepped hole 62 are interference fit. The cylindrical part 7 is generally cylindrical, of course, other shapes are also possible, and the cylindrical part 7 is provided with an inner hole 71 which communicates with the hole 61. [0003] At present, there are several ways to install the cylindrical part 2 in the stepped hole 12 by interfer...
