Embodiment Construction
[0023] refer to Figure 1 to Figure 4 , the base 11 is a flat cube, and the four right angles are chamfered. The main column is a support leg with a triangular section, which is welded by multiple steel plates. Welding work on the base and main column components was completed before arriving on site. During on-site installation, the main column 12 that has been welded as a whole is erected vertically at the four corners of the base 11, and the bottom of the main column and the base are welded together at the welding surface 14 at the bottom of the main column; The tie bars 13 are welded to the welding surface 15 on the side of the main column; so that the base, the main column and the tie bars form a closed integral frame 1 . The overall frame size is 18000×19300×11000mm, with a total weight of 1300 tons.
[0024] refer to Figure 4 , the top mounting plane 16, the side processing plane 17 and the base plane 7 need to be milled.
[0025] refer to Figure 5 to Figure 7 , ...

The invention provides a machining and manufacturing method for an ultra-large type static multifunctional testing machine. An on-site machining and stacking manufacturing method is adopted by a body structure, wherein firstly, main stand column parts and base parts are welded into components respectively in advance, the stand column components and the base components are then transported to a site and then are welded into a whole rack, a first power head is mounted through auxiliary stand columns to carry out milling on a top mounting plane and side machining faces, a virtual shaft tool mechanism is assembled finally, and a method combining virtual shaft machining and manual grinding is adopted to machine a base plane. According to the machining and manufacturing method for the ultra-large type static multifunctional testing machine, bolt connection and other mechanical connection are not needed, and thus the rigidity of equipment is better; the assembling of separated components and the machining amount of connection combined planes are reduced, and thus manufacturing cost is saved; the difficulty that certain components cannot be transported is avoided; the machining process is free of pollution and environmentally friendly.
Description
technical field [0001] The invention relates to a processing and manufacturing method of equipment, in particular to a processing and manufacturing method of an ultra-large dynamic and static multifunctional testing machine. Background technique [0002] In recent years, in the field of industrial technology, there is an increasing demand for ultra-large dynamic and static multifunctional testing machines of the 100 MN level. However, testing machines of this specification are still relatively rare at present. For similar equipment on the market, parts are often processed and manufactured by professional factories, and then assembled to form a complete machine, which is finally installed on site in the form of a complete machine. Due to the large number of components included in the equipment, on the one hand, it leads to a large amount of mechanical processing; on the other hand, due to the large number of connection parts, the rigidity of the machine becomes poor; in addit...
