Integrated three-axis linked compound automatic pressing machine for adapter tubes

Abstract

The invention belongs to the technical field of automobile engine manufacturing, and particularly relates to an integrated three-axis linked compound automatic pressing machine for adapter tubes. The integrated three-axis linked compound automatic pressing machine comprises a machine body, and a horizontal positioning system and a vertical positioning system arranged on the machine body. The horizontal positioning system comprises an integrated three-axis positioning structure and a reverse thrust executing structure arranged on two sides of the machine body respectively. A pressing executing structure, corresponding to the reverse thrust executing structure, is arranged on the integrated three-axis positioning structure. The vertical positioning system comprises an upper limiting structure and a line body lifting structure, which are arranged at the top and bottom of the machine body respectively and correspond to each other. A workpiece to be pressed is placed on the line body lifting structure, and is lifted up by the line body lifting structure to be in contact with the upper limiting structure. The workpiece to be pressed is horizontally positioned by the integrated three-axis lined positioning structure and the reverse thrust executing structure. The integrated three-axis linked compound automatic pressing machine, provided by the invention, is a complete machine of which an integrated X, Y and Z space coordinates positioning device and a pressing mechanism work synchronously, is applicable to two straight adapter tubes and two special-shaped adapter tubes, and can complete compound pressing quickly and effectively.

Description

technical field [0001] The invention belongs to the technical field of automobile engine manufacturing, and in particular relates to an integrated three-axis linkage compound automatic press-fitting machine for connecting pipes. Background technique [0002] In the machinery manufacturing industry, the interference press-fit technology is widely used, especially in the automobile engine manufacturing process, which has an irreplaceable role. In some links, interference press-fitting technology can reduce production costs and improve production efficiency. There are many types of special stand-alone machines that apply interference press-fitting technology in the automotive industry. Piston pin press-fitting machines, valve oil seal press-fitting machines, spark plug conduit press-fitting machines, cylinder head water pipe joint press-fitting machines, crankshaft bearing press-fitting machines, etc. generally use single-axis positioning and single-type press-fitting technolo...

AI Technical Summary

Problems solved by technology

[0004] ①In view of the single working condition and poor compatibility of press-fitting with multiple models in the production line, the improvement method can only set the line body to pass through, and add a single press-fitting machine of the corresponding model, which will increase the production cost virtually, prolong the overall beat of press-fitting, and reduce the improved production efficiency;

[0005] ②There is only one single type of press-fitting tool. For the same type of composite type, this technology is helpless, and the compatibility of the same type of composite type is poor. The improvement method can be equipped with additional mechanisms, which eventually leads to the extension of the overall cycle of press-fitting and reduces production efficiency. ;

[0006] ③ On-line single-axis positioning and press-fitting requires accurate stop position of the conveying line body, which increases the difficulty of manufacturing the line body. If there is an error, the single-axis positioning cannot be corrected, and the line body press-fitting table needs to be adjusted. Convenience; Off-line single-axis positioning and press-fitting can reduce the difficulty of manufacturing the wire body, but because the workpiece needs to be operated off-line, it seriously affects the press-fitting rhythm, and the handling becomes cumbersome
