Fixing device for aluminum alloy shell bus duct machining

Abstract

The invention discloses a fixing device for aluminum alloy shell bus duct machining. The fixing device comprises a base, a sliding groove, sliding blocks, a moving mechanism, bearing seats, distributed self-adaptive attaching damage-preventing pressing fixing mechanisms, magnetic shape memory driving inner supporting type mechanisms, a supporting table, electrorheological effect viscosity change damping mechanisms and a placing table. The invention belongs to the technical field of aluminum alloy shell bus duct machining, and particularly relates to the fixing device for the aluminum alloy shell bus duct machining. The fixing device can fit the shape of the outer wall of an aluminum alloy shell bus duct to uniformly disperse fixing force and avoid poor fixing effect caused by non-uniform fixing force or deformation caused by excessive stress at a certain position of the aluminum alloy shell bus duct, and meanwhile can penetrate into the aluminum alloy shell bus duct to support the inner wall of the aluminum alloy shell bus duct, so that the overall fixing and supporting effect is better, damping is carried out through the change of the viscosity of electrorheological liquid of the electrorheological effect, and damage to the aluminum alloy shell bus duct during machining and fixing is avoided.

[0002] Busway is a new circuit method called "Bus-Way-System" developed by the United States. It uses copper or aluminum as a conductor, supports it with non-olefinic insulation, and then installs it into a metal groove to form a new type of conductor. , the real practical application in Japan was in Showa 29 (that is, 1954). Since then, busway has been developed, and now it has become an indispensable wiring method in high-rise buildings, factories and other electrical equipment and power systems. , factories and other building power needs, and this demand has a tendency to increase year by year. Using the original circuit wiring method, that is, the pipe-through method, brings many difficulties during construction. Moreover, when changing the power distribution system, it is necessary to It is almost impossible to make it simpler, but if the busway is used, it is very easy to achieve the goal, and it can also make the building more beautiful, but in the process of processing the busway of the aluminum alloy shell, the existing The clamping and fixing performance of the fixing device is poor, which is not conducive to the later processing work, and the existing fixing device for busbar groove processing of aluminum alloy shell has poor shock resistance, which is easy to cause damage to the equipment, reduces the service life, and increases the production cost. In addition, the aluminum alloy used in the busway of the aluminum alloy shell has a low density, but its strength is relatively high, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. Widely used, the amount of use is second only to steel, but the busway of the aluminum alloy casing is generally processed into a thin-walled shell type with a hollow inner wall. When fixing the busway, it is very likely that the busway of the aluminum alloy casing will be damaged due to excessive fixing The deformation of the groove is damaged, and the outer wall of the busway of the aluminum alloy casing has protrusions and depressions, which is not composed of a smooth outer wall, so when fixing the busway of the aluminum alloy casing, it is difficult to apply the fixing force evenly on the busway of the aluminum alloy casing , so the fixed effect is not ideal
