Multi-truss wood truss assembling equipment

Abstract

The invention discloses multi-truss wood truss assembling equipment. The multi-truss wood truss assembling equipment comprises a rack, a drilling mechanism, a feeding mechanism and a pressing pin grabbing mechanism, and the drilling mechanism, the feeding mechanism and the pressing pin grabbing mechanism are arranged on the rack; the rack comprises a longitudinal gantry moving mechanism, the longitudinal gantry moving mechanism comprises a pair of longitudinal guide rails, a portal frame and a longitudinal power mechanism, the portal frame comprises a cross beam and stand columns used for supporting the cross beam, and sliding bases matched with the longitudinal guide rails are arranged at the bottoms of the stand columns; and the feeding mechanism is arranged on the stand columns, and thedrilling mechanism and the pressing pin grabbing mechanism are connected with the cross beam through a transverse moving mechanism. The multi-truss wood truss assembling equipment can automatically move to corresponding machining positions according to the assembling requirements to achieve automatic drilling and pin assembling integration operation of a multi-truss wood truss, the error requirements in design and practical production are met, therefore, the assembling efficiency of the multi-truss wood truss is improved, the labor intensity is reduced, and the assembling quality of the multi-truss wood truss is improved.

Description

technical field [0001] The invention relates to multi-truss assembling equipment, which belongs to the technical field of wood truss processing. Background technique [0002] Due to its excellent performance, light wood trusses are widely used in the roof and floor systems of modern wooden structures and urban "slope conversion" projects; in light wood structures, in some heavy-duty structures, single wood trusses It can no longer meet the design needs, and needs to be solved with multi-truss wood trusses. Multi-truss trusses are composed of multiple pieces of single-truss through connectors. Multi-timber trusses are generally used in key parts of roof or floor systems. The stress environment of the concentrated load transmitted by the lapped common single-truss is more complex than that of the common single-truss. This kind of multi-truss, which is composed of multiple single-trusses, has also become the most commonly used structural form at the key load-bearing nodes of ...

Problems solved by technology

There are two fatal shortcomings in this production method: positioning, drilling, and pinning are carried out through manual assembly. Affected by the proficiency of workers and the quality of assembly, the strength of the multi-truss designed by calculation is often compared with the strength of the actual produced wood truss. The error is very large, which greatly reduces the strength of the multi-wood truss; because it is a purely manual operation, it needs to be positioned first, then drilled, and finally installed with pins. If the entire process is completed manually, it is obviously extremely inefficient and the assembly quality is not high. , so the existing assembly process generally cooperates with positioning tooling, punching tooling and pinning tooling to ensure the quality of assembly. Even so, the production efficiency is not high, and the labor intensity is also large, resulting in a large error between design and actual production. , so that the strength of multi-wood trusses is greatly reduced
