Problems solved by technology

[0004] However, the shape and position accuracy of the standard joint produced in this way is low, such as the difference in parallelism between the upper and lower contacting end faces, the verticality difference between the pin shaft holes, etc., which will lead to low assembly accuracy of the standard joint during assembly.

Abstract

The invention provides standard knot machining equipment, and relates to the field of tower cranes. The standard knot machining equipment comprises a workbench, a clamping unit, a boring unit and a milling unit. A connecting piece is arranged on the clamping unit; the boring unit is connected with the workbench; the milling unit is arranged on the workbench in a sliding mode. And the clamping unit is connected with the workbench through one group of connecting pieces after clamping and fixing the standard knot. And the milling unit slides on the workbench and is used for milling the contact end surfaces of the main chord members in sequence. The boring units are arranged at the two opposite top corners of the tail end of the standard knot in pairs and can be used for boring shaft holes of two main chord members at the same time. After rotating by 90 degrees, the clamping unit is connected with the workbench through the other set of connecting pieces, and the boring unit bores shaft holes in the remaining two main chord members. And finally, machining of the standard knot formed through tailor-welding is completed, so that errors caused by tailor-welding are avoided, the form and position precision of the standard knot can be accurately controlled, and then the assembling precision of the standard knot during assembling is improved.

Description

technical field [0001] The invention relates to the field of tower cranes, in particular to standard section processing equipment. Background technique [0002] The standard section is a tower section with a standard size used to change the height of the tower body in the tower crane. It is composed of four main chords, several cross bars and oblique webs, and the four main chords are respectively located at the four vertices of the quadrilateral. place. According to the cross-sectional shape of the main chord, the standard section of the tower crane is divided into a square tube structure, an angle steel structure and a round tube structure. [0003] Restricted by processing equipment, the existing standard section usually adopts the process of machining first and then tailor welding in the production process, that is, the main chord is machined separately, and then the main chord, cross bar and diagonal web are assembled Welding fixed. Among them, the machining includes...
