Automatic layering placement rack for workpieces

Abstract

The invention belongs to the technical field of automobiles, and particularly provides an automatic layering placement rack for workpieces. The automatic layering placement rack for the workpieces comprises a base frame and at least one set of two linkage positioning mechanisms; each linkage positioning mechanism comprises at least two positioning pieces arranged at intervals in the vertical direction, and in every two adjacent positioning pieces, the end face, facing the lower positioning piece, of the upper positioning piece is provided with a linkage piece; and each linkage positioning mechanism has a no-load state in which all the positioning pieces are not in linkage, the upper positioning pieces are located in a base column and the lower positioning piece partially stretches out of the base column, a bearing state in which the lowermost positioning piece is pressed downwards to rotate to a flat placement position under the gravity action of the to-be-positioned workpieces to stretch out of the base column, and an open state in which the upper positioning pieces are in linkage with the lowermost positioning piece through the linkage pieces to rotate to partially stretch out ofthe base column. The positioning pieces of each linkage positioning mechanism are in linkage under the gravity action of the to-be-positioned workpieces, and then the workpieces can be sequentially placed in a layering manner from top to bottom; and the automatic layering placement rack for the workpieces is simple in structure and high in linkage performance.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a material rack for automatic layering of workpieces. Background technique [0002] In the automatic production process of automobiles, the same automobile body parts need to be produced in large quantities. In order to effectively save the space layout of the production line, racks with multi-layer supports are generally used for storage and transportation. Most of the positioning mechanisms used to support parts in the existing layered racks are driven by pneumatic components such as cylinders; if each positioning mechanism is driven by a pneumatic component, it will lead to high manufacturing costs and maintenance costs. It takes up a lot of space; if all the positioning mechanisms are jointly driven by a pneumatic component to achieve linkage, the structure will inevitably be more complicated; and the positioning mechanism of the general layered material rack ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing layered material rack realizes the placement of workpieces through the linkage of connecting rods, resulting in a small number of support blocks in the material rack, and a small number of workpieces that can be placed. In addition, once the connecting rod breaks, the entire material racks will not be able to achieve linkage
