Problems solved by technology

If there is a large processing error in the machining process of the plate, the welding deformation may amplify this error, resulting in a larger error of the upper support after processing, which cannot meet the accuracy requirements, and the product has a high scrap rate
In addition, the existing processing methods need to reposition the processed holes in different processes, which increases the processing time and reduces production efficiency

Embodiment

[0048] see figure 1 and figure 2 , This embodiment provides a tower crane upper support machining center for processing the end surface mounting holes 123 of the welded upper support 100 and the side mounting holes (111, 121, 122) on both sides. That is to say, the structural parts constituting the upper support 100 are assembled together by tailor welding, and then the machining center for the upper support of the tower crane provided in this example is processed on the end face and the two opposite sides of the upper support 100 respectively. End surface mounting holes 123 and side mounting holes. The side mounting holes are divided into a first side mounting hole 111 , a second side mounting hole 121 and a third side mounting hole 122 .

[0049] Specifically, the upper support 100 is a truss structure, the upper end of the upper support 100 is provided with a top seat 110, the lower end of the upper support 100 is provided with a base 120, and the top seat 110 and the ba...

Abstract

The invention provides a tower crane upper support machining center, and relates to the field of machine tool equipment. The machining center for the upper support of the tower crane is used for machining end face mounting holes of the welded upper support and side face mounting holes in the two sides of the welded upper support. According to the machining center for the upper support of the tower crane, the upper support is horizontally positioned through a positioning seat in the clamping module, the upper support is fixed through a clamping mechanism in the clamping module, and then an end face mounting hole in the end face of the upper support and side face mounting holes in the two side faces of the upper support are machined through the end face machining assembly and the two side face machining assemblies correspondingly. Therefore, according to the machining center for the upper support of the tower crane, machining of the end face mounting holes and the side face mounting holes in the two side faces can be completed only through one-time clamping and positioning, multiple clamping procedures are omitted, meanwhile, errors caused by multiple times of positioning and clamping in pre-welding machining are avoided, and the machining efficiency and the machining precision are improved.

Description

technical field [0001] The present application relates to the field of machine tool equipment, and in particular, to a machining center for an upper support of a tower crane. Background technique [0002] As a kind of lifting equipment in the construction field, tower cranes are often used for vertical and horizontal transportation of materials and installation of building components. As one of the key components, the upper support of the tower crane is mainly used to connect the balance arm, boom, swing lower support and tower cap of the tower crane. [0003] The upper support is formed by tailor welding of multiple plates, and the base part of the upper support has the functions of support, connection and rotation. The end face mounting holes for the connection of the slewing bearing, the two sides of the upper support close to the base are provided with four side mounting holes respectively connected with the balance arm and the boom arm, and the two sides of the top sea...
