Manufacturing and installing-clamping tool and manufacturing technology of ultralow-temperature subway transmission box

Abstract

The invention discloses a manufacturing and installing-clamping tool and a manufacturing technology of an ultralow-temperature subway transmission box. The problem that a machining and installing-clamping procedure of an oil passage hole of a subway transmission box are complex is solved, the installing-clamping procedure can be reduced by the manufacturing and installing-clamping tool and the manufacturing technology of the ultralow-temperature subway transmission box, the production efficiency is improved, and meanwhile, the positioning of the workpiece is accurate, and the error can be reduced. According to the technical scheme, the tool comprises a horizontal rotating disc which is fixedly connected with the subway transmission box, the horizontal rotating disc is rotatably connected with a rotating bottom plate so as to drive the subway transmission box to realize longitudinal turnover; the rotating bottom plate is connected with a transverse turnover mechanism, and the transverseturnover mechanism drives the rotating bottom plate to rotate so as to realize transverse turnover of the subway transmission box; and the transverse turnover mechanism comprises a vertical directional rotating disc which is fixedly connected with the rotating bottom plate, and the vertical directional rotating disc is driven by the rotating device to rotate inside a vertical plane.

Description

technical field [0001] The invention relates to the field of casting equipment and advanced processing technology, in particular to a manufacturing clamping tool and manufacturing process of an ultra-low temperature subway transmission box. Background technique [0002] With the release of my country's foundry industry development planning documents, it is required to overcome the casting technology of key core castings in the fields of energy power, rail transit, aerospace and other fields; develop key common technology research and give priority to the development of major technical equipment. Ductile iron has excellent mechanical properties of low temperature resistance, and is mainly used in important equipment components in cold regions. At present, the low temperature resistance of ductile iron in my country is generally -20°C and -40°C. However, as the operation of subway trains and subways expands to lower temperature areas, its components are required to meet relev...

Problems solved by technology

Drilling these holes generally requires one tooling to drill one type of hole. Multiple toolings are required to drill oil passage holes in a box, and multiple clamping and dismounting are required. Moreover, the workpiece is relatively heavy, and the clamping and dismounting is laborious and laborious.

[0004] To sum up, in the prior art, there is still no effective solution to the problem of complex machining and clamping process of the oil passage hole of the subway transmission box
