One-piece three-axis linkage composite automatic press-fitting machine

Abstract

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. It includes the body and the horizontal positioning system and vertical positioning system set on the body. The horizontal positioning system includes an integrated three-axis linkage positioning structure and a reverse thrust execution structure respectively arranged on both sides of the body. The integrated three-axis linkage positioning structure is equipped with The press-fit execution structure corresponding to the reverse thrust execution structure, the vertical positioning system includes the corresponding upper limit structure and the line body jacking structure respectively set on the top and bottom of the machine body; the workpiece to be pressed is placed on the line body jacking structure , and lift up through the line body jacking structure to contact with the upper limit structure, and the integrated three-axis linkage positioning structure and reverse thrust execution structure perform horizontal positioning of the workpiece to be pressed. The present invention is a complete machine in which an integrated X, Y, Z space coordinate positioning device and a pressing mechanism work synchronously. The mechanism quickly and effectively completes composite pressing for two kinds of straight connecting pipes and two kinds of special-shaped connecting pipes.

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
