Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a large-scale fixed-beam gantry splicing workbench. Background Art

[0002] The traditional large gantry worktable is cast in one piece, which is difficult to cast and process. The worktable casting is greatly deformed and the length that can be produced is limited, which makes the production of large gantry equipment difficult and the production cycle long. The machine tool worktable is one of the important components of the machine tool. The size of the machine tool worktable surface is one of the bottlenecks that hinder the development of machine tools to large and super-large machine tools at this stage. Choosing a spliced ​​worktable is an effective solution, but it also brings many problems such as unstable accuracy. The existing worktable connection types include locating keys, locating pins, locating key and pin combinations, etc. These positioning methods can meet the accuracy requirements, but their precise positioning is difficult to achieve and cannot meet the requirements of high-precision machine tool workbenches. The accuracy has to be readjusted during the secondary assembly, which cannot meet the requirements of rapid assembly. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a large fixed-beam gantry splicing workbench. Through the mutual cooperation of the fixed-beam gantry assembly and the quick positioning assembly assembly, when in use, a push-pull block is arranged on the left and right of the workbench splicing, and the position of the workbench can be adjusted to achieve the purpose of quick positioning and assembly, thereby improving the assembly efficiency. A glue pouring groove is designed at the splicing to avoid poor precision stability and easy deformation due to less splicing surface combination, while reducing the precision requirements of the end face of the workbench and reducing the processing difficulty.
