A New Type of Gravity Casting Soup Feeding Machine Double Pouring Spoon Manipulator

Abstract

The invention discloses a novel double-pouring ladle mechanical arm for a gravity casting fluid feeding machine. The mechanical arm comprises a working arm, a first pouring ladle, a second pouring ladle driving mechanism and a second pouring ladle, wherein the first pouring ladle is fixedly connected with the left end of a sprocket shaft, and the second pouring ladle driving mechanism is fixedly connected with the right end of the sprocket shaft; the second pouring ladle driving mechanism comprises a shell, a servo motor, a pinion, a bull gear, a lead screw, a ball nut, a connecting plate, a front support and a rear support, and the second pouring ladle is fixedly connected with the right end of the connecting plate. The double-pouring ladle mechanical arm is novel and reasonable, simple in structure, and fast and stable in operation, and can be matched with a small-size melt furnace for use; the problem that the double-pouring ladle device of the mechanical arm is interfered with the melt furnace is solved, pouring at sprues with different distances in gravity casting is realized, the mechanical arm can be mounted on a five-rod fluid feeding machine for use, massive manpower is saved, the production cost is reduced, the production efficiency is improved, and the technical content is high.

Description

technical field [0001] The invention relates to casting mechanical equipment, in particular to a double pouring ladle mechanical arm used for a gravity casting soup dispenser. Background technique [0002] At present, metal mold gravity casting is widely used in the production of various non-ferrous castings due to its relatively simple equipment, relatively small investment in molds and equipment, and relatively simple casting process. However, most of the work of metal pouring for gravity casting molds is done manually. The pouring work is heavy physical strength and high-risk work. Moreover, the foundry workshop is noisy, dusty, and the working environment is very harsh. Those who have been engaged in metal pouring work in the foundry workshop for a long time Workers have a high probability of suffering from occupational diseases such as pneumoconiosis. In order to reduce the labor intensity of workers and save labor costs, it is necessary to use gravity casting robots to...

Problems solved by technology

[0003] The application number is 201120359585.8, and the utility model patent named "robot double ladle pouring arm" proposes to use two servo motors to drive two ladles respectively through two reducers and chain sprocket mechanisms. The distance can be changed by adjusting the installation position of the pouring spoon on the adjusting plate. The biggest problem with this pouring arm is that when pouring a specific mold, the distance between the two pouring spoons is adjusted to be the same as the distance between the two gates. , until the next time the mold is replaced, manually adjust the position of the pouring spoon on the adjustment plate, and when the distance between the two gates is too large, the distance between the two pouring spoons will also increase accordingly, requiring a large-sized melt furnace to match it Matching, otherwise it will cause the pouring arm to interfere with the molten furnace when taking molten metal

[0004] In addition, the multi-degree-of-freedom industrial robots produced by companies such as KUKA and ABB in Germany can complete double-gate gravity casting, but they are mostly used as automatic casting production lines, and their prices are high, far beyond the range of ordinary small and medium-sized enterprises. The distance between the two pouring spoons is fixed during pouring. When changing the mold, the industrial robot must be modified. Its flexibility is poor and it can only be used for mass production.
