A stainless steel tube abrasive flow wiping fixture

Abstract

The invention discloses an abrasive flow wiping fixture for a stainless steel pipe. The fixture is characterized by comprising an upper guiding baffle, a lower guiding baffle, a bearing sleeve and a limiting sleeve, wherein the lower surface of the upper guiding baffle is closely combined with the upper end of the bearing sleeve; the upper surface of the lower guiding baffle is closely combined with the lower end of the bearing sleeve; the limiting sleeve is closely arranged in the bearing sleeve, and is parallel to the upper and lower guiding baffles; a plurality of insertion holes with the diameters equal to the external diameter of the stainless steel pipe are correspondingly formed in the upper and lower guiding baffles and the limiting sleeve. According to the abrasive flow wiping fixture, the pressure of an abrasive flow machine tool can be effectively dispersed and born, and the situation that the stainless steel pipe is bent and deformed by the pressure of the abrasive flow machine tool in a wiping process can be avoided; a plurality of stainless steel pipes can be simultaneously and fixed and wiped, so that the wiping efficiency and wiping effects are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and pipeline cleaning, and in particular relates to a fixture used for wiping multiple stainless steel tubes of equal length with abrasive flow. Background technique [0002] As an important carrier for long-distance transportation of oil and gas, stainless steel pipes are playing an increasingly prominent role in modern industrial construction. Especially in the field of aerospace, there is a high requirement for the purity of the gas and liquid to be transported, so there is a high requirement for the cleanliness of the inner wall of the transport pipeline. At present, the cleaning and wiping of the inner wall of the stainless steel pipe is still mostly solved by using a push-pull cleaner, which has low wiping efficiency and is difficult to guarantee the wiping effect. However, there is no systematic product for the new abrasive flow wiping technology for the inner wall of the st...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above shortcomings, improve the wiping efficiency, improve the wiping effect, and solve the problems that multiple stainless steel pipes of equal length cannot be firmly fixed at the same time in the above technology, and the stainless steel pipes are prone to deformation during the abrasive flow wiping process. , so as to provide a fixture that can be conveniently operated, accurately and reliably realize abrasive flow wiping of multiple stainless steel tubes of equal length at the same time
