A kind of crimping auxiliary tool for automobile air-conditioning pipe fittings

Abstract

The invention provides an assistive device for covering pressing of an automobile air conditioner pipe fitting and belongs to the technical field of automobile air conditioner pipe fitting machining equipment. The upper portion of a positioning stop block (1) of the assistive device for covering pressing of the automobile air conditioner pipe fitting is provided with a concave positioning groove (2), the positioning stop block (1) is connected with a movable block (4) through a slide block I (3), and the movable block (4) is connected with a fixed block (6) through a slide block II (5); the slide block I (3) is clamped and installed in an open groove in the upper portion of the movable block (4), and a spring I (7) is arranged between the inner wall of the side face of the slide block I (3) and the inner wall of the side face of the movable block (4); and the slide block II (5) is clamped and installed in an open groove in the side face of the fixed block (6), and a spring II (8) is arranged between the inner wall of the slide block II (5) and the inner wall of the fixed block (6). The assistive device for covering pressing of the automobile air conditioner pipe fitting is simple in structure and capable of achieve reliable and accurate fixing and positioning effects on the pipe fitting, so that the situation that the pipe fitting is deformed due to force applying of a coveringpressing die is avoided, and the covering pressing quality of the pipe fitting is improved.

Description

technical field [0001] The invention belongs to the technical field of processing equipment for automobile air-conditioning butlers, and more specifically relates to a crimping auxiliary tool for automobile air-conditioning pipe fittings. Background technique [0002] With the continuous development of the automobile industry, the types of air-conditioning pipe fittings continue to increase, but these air-conditioning pipe fittings are inseparable from process steps such as adding rubber hoses and crimping. After the pipe fitting is crimped, the front of the crimped sleeve will extend. If the pipe fitting is positioned with a positioning block, the crimping will cause the pipeline to deform after the positioning block is squeezed. Therefore, when the pipe fittings are crimped in the prior art, the pipe fittings are directly crimped on the crimping mold without a positioning stopper, the crimping size is inaccurate, or the front end of the sleeve is extended to extrude the po...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a simple structure for the deficiencies of the existing technology, which can reliably and accurately fix and position the pipe fittings when the crimping mold is crimping the air-conditioning pipe fittings, and when the crimping mold exerts force on the When the pipe fitting is put on, it can play a buffering role, avoid the deformation of the pipe fitting caused by the force of the crimping mold, and improve the quality of the finished product of the crimping process of the car air-conditioning pipe fittings.
