Description

Technical Field

[0001] The utility model application relates to the technical field of ladle tooling mechanisms, in particular to a ladle tooling mechanism of casting equipment using chain drive. Background Art

[0002] Pouring robots are mainly used for pouring operations in harsh working environments. The performance requirements for robots are different from those for general industrial robots. As the use of robot casting in casting equipment becomes increasingly popular, the ladle tooling used in existing robot casting has problems such as complex structure, high cost, and high manufacturing precision requirements.

[0003] Many of the existing general ladle tooling adopts structures such as gear rack transmission or bevel gear transmission. Due to the characteristics of the gear parts themselves and the influence of manufacturing errors and assembly errors, it is easy to have an empty stroke phenomenon during use. Since the ladle tooling works in a high temperature environment, the ambient temperature can be as high as 600°C or above, the ladle tooling with a gear structure is prone to jamming, resulting in discontinuous rotation of the ladle, affecting the casting quality. In addition, the gear structure has high requirements for processing and assembly accuracy, and maintenance and repair are relatively complicated, and the manufacturing cost and use cost are relatively high. Summary of the invention

[0004] In order to solve the problem that the existing casting equipment ladle fixture mechanism is prone to discontinuous rotation of the ladle due to excessively high temperature during casting, the utility model provides a casting equipment ladle fixture mechanism using chain drive to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, a side of the tooling arm away from the ladle body is provided with a plurality of air holes, and a side of the tooling arm close to the ladle body and the connecting shaft are both provided as heat insulation plates.

[0008] Furthermore, the top of the heat-insulating cover shell is configured to be open, and the height of the tooling arm is greater than the height of the ladle body.

[0009] Furthermore, a tensioning plate is provided on the inner side of the driven sprocket on the side of the driving sprocket, and the tensioning plate is detachably fixed to the inner wall of the tooling arm by bolts.

[0010] Furthermore, the ladle mounting piece is composed of a clamping sleeve block and a triangular plate, the clamping sleeve block is clamped and fixed to the outer surface of the connecting shaft by bolts, and the bottom surface of the ladle mounting piece is fixedly connected to the ladle body by bolts.

[0011] Furthermore, one side of the ladle body is configured to be in a pointed shape, and a side plate for connecting with a ladle mounting piece is fixed to the outer surface of the ladle body close to the tooling arm.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the servo motor is used as the driving mechanism, the position and speed control mode are accurate in action and flexible, and it is suitable for various casting processes. The reducer is a precision planetary reducer with large transmission torque, good rigidity, small backlash and stable operation. The servo motor and the reducer are covered with a heat-insulating cover to effectively prevent the influence of the ambient temperature.

[0014] 2. In the utility model, through the detachable ladle design, when the ladle is damaged during use, the ladle can be replaced separately, and the heat insulation effect of the ladle mounting can further block the heat transfer between the ladle and the transmission chain and the driven sprocket. Combined with the flexibility of the chain drive and the lack of transmission backlash, it is ensured that the ladle moves without jamming and empty travel. BRIEF DESCRIPTION OF THE DRAWINGS
