Porcelain sleeve assembling tool

Abstract

The invention belongs to the technical field of tool manufacturing, and relates to a porcelain sleeve assembling tool. The assembling tool comprises a positioning body and a pushing device. The positioning body is provided with a T-shaped guide rail. The pushing device is composed of a push rod, a guide rod and a base plate. The assembling tool is applied to the product assembling process of a structure composed of a similar thermocouple, porcelain sleeve assembling which is completed manually is changed into machine production by means of the tool, the assembling time is short, only about 10 s is needed for assembling every porcelain sleeve, no intermittence or pause exists in assembling of multiple porcelain sleeves, continuous operation is achieved, and the production efficiency is multiple or even tens of times that of manual penetration. The porcelain sleeves are concentrically installed in a sleeve pipe hole, the centering precision reaches 0.05-0.1 mm, the phenomenon that porcelain sleeves are inclined when penetrated manually is changed, the porcelain sleeves are successfully compacted, building block type butt joint of the porcelain sleeves is achieved, and the phenomena of reworking, raw material scrapping and manual labor hour waste are avoided.

Description

technical field [0001] The invention belongs to the technical field of tooling manufacturing and relates to a porcelain sleeve assembly tool. Background technique [0002] At present, for products with a structure similar to thermocouples, the porcelain sleeve is worn on the core wire and loaded into the outer sleeve. The most commonly used method is to rely on the operator to manually insert the core wire into the porcelain casing, align the center of the casing and put it into the casing, and then manually compact the porcelain casing. The production method is backward and the work efficiency is not high. [0003] When the gap between the porcelain sleeve, core wire, and outer sleeve is small, because the assembly of the porcelain sleeve and the outer sleeve hole is tilted, or the non-concentricity causes the contact between the hole walls to generate friction, as the porcelain sleeve and the outer sleeve hole The longer the bonding length, the greater the friction force,...

The most commonly used method is to rely on the operator to manually insert the core wire into the porcelain sleeve, align the center of the sleeve and put it into the sleeve, and then manually compact the porcelain sleeve. The production method is backward and the work efficiency is not high.

[0003] When the gap between the porcelain sleeve, core wire, and outer sleeve is small, because the assembly of the porcelain sleeve and the outer sleeve hole is tilted, or the non-concentricity causes the contact between the hole walls to generate friction, as the porcelain sleeve and the outer sleeve hole The longer the bonding length, the greater the friction force, the larger the gap between the porcelain sleeves, the porcelain sleeves cannot be compacted, and it is difficult to penetrate the porcelain sleeves
