Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0043] The invention improves the processing flow of each component (including the rear guide rail body and the left and right slide rails), reduces or controls the amount of denaturation; improves the processing and assembly process of the left and right slide rails, and reserves a processing allowance to be assembled to the rear guide rail body After the groove is processed to the design size; finally, the left and right beading is installed to ensure that the size of the working surface (chute) required by the design meets the requirements, specifically including the following steps:

[0044] 1) Processing of the rear guide rail body

[0045] Process flow of rear rail body processing:

[0046] Scribing and milling processing line—rough milling shape—artificial aging—fin...

Abstract

The invention provides a processing and assembling method for a linear combined guide rail of a box body. The processing and assembling method comprises the following steps of processing a back guide rail body by marking a milling line, roughly milling an appearance, performing artificial aging, finish-milling the appearance, drilling holes, milling two end faces, marking hole lines and boring; processing left and right slide rails by drilling hanging holes, quenching and tempering, straightening, planing all sides, marking planing lines, planing steps, milling appearances, drilling center holes and drilling holes; processing left and right depression bars by straightening, milling appearances, milling lengths, milling arcs, drilling center holes and drilling holes; sleeving parts together, mounting the left and right slide rails, milling sliding surfaces and depression bar mounting faces, and mounting the left and right depression bars for assembly. According to the processing and assembling method, the work efficiency and the product quality are improved, and the first-pass yield of product assembly is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and assembly, and relates to the processing and assembly of components of guide rails after box bodies are combined. Background technique [0002] The rear guide rail combination is an important part used to provide storage and storage for storage and transportation items in the box; the linear rear guide rail type guide rail is generally a structural assembly, mainly composed of rear guide rails, left slide rails, right slide rails, and left slide rails. Beads, right beads, etc.; the rear guide rail is a box-shaped cast aluminum part (340mm×190mm×2500mm) with a relatively complex structure and a long size; the left and right slide rails are slender and tempered (hardness: HRC35~40) The steel parts (10mm×60mm×2500mm); the left and right beadings are slender steel parts (20mm×30mm×2500mm) with a “Z” cross-section. [0003] The processing and assembly of the guide rail after the box b...
