Portable spliced guide rail, butt joint method and work fixture

Abstract

The invention discloses a portable spliced guide rail, a butt joint method and a work fixture. The spliced guide rail is divided into a base section part, an extension section and a tail section which are mutually in butt joint along a cross section direction, wherein butt joint faces are connected in a mutual intersection manner, so that the defects of poor butt-joint stability, low connection strength and difficult in precision guarantee on the same horizontal plane are avoided. On the butt joint faces of a guide rail body, two pairs of positioning pins and positioning holes are adopted, sothat the positioning is accurate and the positional connection is reliable; guide posts and guide faces are mutually matched so that the splicing accuracy is enhanced; and auxiliary dowel shafts are used for fixed connection so that the structural stability and the integrity of the spliced guide rail are ensured, and the specially designed work fixture ensures that the butt joint process of the guide rail is more accurate and easier to operate. The entire spliced guide rail has a simple structure, is convenient for butt joint, and can be dismounted and assembled without professional personnel, and the extended guide rail is beneficial to enlargement of an applicable range for product processing and is suitable for popularization and application in various industries and fields.

Description

technical field [0001] The invention relates to a portable splicing guide rail and its docking method, as well as a fixture designed for making the guide rail, and belongs to the field of mechanical processing equipment. Background technique [0002] With the needs of industrialized production, the requirements for the transportation and use of processing machinery are getting higher and higher, and the scope of application of its processing is becoming wider and wider. Among them, the portable guide rail is produced to improve transportability, reduce volume and reduce weight. Portable guide rails are usually composed of guide rails and beams of a certain length. The beams are made of aluminum-plastic profiles, with a stable structure and light weight. Guarantee the connection accuracy of the guide rail and the beam. Because of its simple structure, convenient movement, flexible assembly, and high processing accuracy, it has been widely used in processing equipment in vari...

Problems solved by technology

However, as the scope of application increases, its structure also reflects its shortcomings: that is, due to the limitation of the length of the guide rail, the size of the processed workpiece cannot be too large

Although the existing guide rails can also be spliced, the splicing process requires professional and technical personnel to operate. The splicing speed is slow and the splicing quality cannot be guaranteed, which brings troubles to the enterprise and increases the burden on the after-sales work, thus indirectly affecting the machine. use and sale
