The application discloses a large-scale assembled foundation platform and a construction method thereof. The large-scale assembled foundation platform comprises a functional box girder group and a foundation embedded part; the functional box girder group comprises a main bearing box girder, a secondary bearing box girder, a lateral auxiliary box girder and a public engineering box girder, and the functional box girders are combined according to requirements through bolts; and the foundation embedded part comprises a transition welding plate connected with the bottom of the functional box girder group and a pre-embedded plate embedded in concrete. Compared with a traditional construction method, the large-scale foundation platform and the construction method thereof have the advantages of high structural strength, high plane precision, disassembly and assembly, iteration, flexible use, shortened manufacturing period, cost saving, reduced occupation time of a large-scale crane and the like, and are particularly suitable for occasions with large on-site construction difficulty and lack of construction machines.

This invention relates to a precision and efficient operating device and method for a CNC column-moving surface grinder. The device includes a separate arrangement of the front bed with V-shaped guideways A and B, and the rear bed with V-shaped guideway C and linear guideways. Each of the V-shaped guideways A, B, and C is configured as a segmented, thermally symmetrical structure. Each segment of V-shaped guideway A, B, and C is equipped with a cooling structure and a temperature sensor, as well as an air inlet pipe and a solenoid valve. Independent intelligent temperature control of each guideway segment is achieved through a PLC controller and an air cooler. This invention solves the problems of distortion caused by thermal expansion and deformation due to sliding friction in existing integral V-shaped guideways, as well as the technical challenges related to the process. It also addresses the issues of excessive tolerances in the surface accuracy of the table, the stability of the reciprocating linear motion of the slide, and the technical difficulties of excessive surface accuracy and superimposed mixed grinding marks in high-efficiency grinding precision machining of parts.
