Five-rod fluid feeding machine double-pony ladle mechanical arm

Abstract

The invention discloses a five-rod fluid feeding machine double-pony ladle mechanical arm. The five-rod fluid feeding machine double-pony ladle mechanical arm comprises an arm driving mechanism and a pony ladle driving mechanism, wherein the arm driving mechanism is connected to a fixed plate; a gear mechanism is driven to rotate by a servo motor so as to drive the rotation of the mechanical arm; the pony ladle driving mechanism utilizes the servo motor to drive the gear mechanism to realize meshing motion, sprocket wheels on a sprocket shaft are driven, a sprocket wheel chain mechanism is driven, a pony ladle adjusting plate and a pony ladle are driven to rotate, and fluid fetching and injection actions are realized; the micro change of a position is realized by changing mounting holes in the adjusting plate, and the position is more accurate. The five-rod fluid feeding machine double-pony ladle mechanical arm is matched with a solution furnace with a small size for use, the problem that a mechanical arm double-pony ladle device intervenes with the solution furnace is solved, moulds with different distance sprues are poured, the mechanical arm can be mounted on a five-rod fluid feeding machine for use, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to casting mechanical equipment, in particular to a five-link soup feeding machine double ladle mechanical arm used for gravity casting. technical background [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 gravity casting work is done manually. The work is heavy physical strength and high-risk work. In addition, the foundry workshop is noisy, dusty, and the working environment is very harsh. The probability of occupational diseases such as pneumoconiosis Larger, in order to reduce the labor intensity of workers and save labor costs, it is necessary to use gravity casting robots to replace manual pouring of molten metal. The mature product currently used in die-casting operations is the five-link soup feeding machine....

Problems solved by technology

[0003] The application number is 201120359585.8, and the utility model patent named "Robot Double Ladle Arm" proposes to use two servo motors to drive two ladles respectively through two reducers and chain sprocket mechanisms. The distance between the two ladles It can be changed by adjusting the installation position of the pouring spoon on the adjustment plate. The biggest problem with this arm is that when the distance between two gates is too large for a certain mold, the distance between the two pouring spoons will also increase accordingly. A large-sized melting furnace is required to match it, otherwise it will cause the arm to interfere with the melting 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. When the distance between the two pouring spoons is fixed, the industrial robot must be transformed when the mold is replaced. Its flexibility is poor and it can only be used for large-scale production.
