[0018] In one embodiment of the present invention, such as Figure 1-12As shown, an automated production line for casting, cooling, cutting, and sand removal of motor housings includes a casting cooling zone 11, a sand removal cutting zone 12, a casting cooling assembly 13, and a sand removal cutting assembly 14. The sand removal cutting zone 12 is located between the two casting cooling zones 11, and the sand removal cutting assembly 14 is provided in the sand removal cutting zone 12. The casting cooling zone 11 is provided with the casting cooling assembly 13. The casting cooling assembly 13 includes a first robot 21, a servo-driven gravity casting machine 22, a casting mold, a mixer 3, a holding furnace 24, a seven-axis casting system, a casting part removal fixture, a cooling fixture 5, and a turnover fixture 6. The casting mold is installed on the servo-driven gravity casting machine. The gravity casting machine 22 has a seven-axis casting system mounted on the first robot 21, and a casting and part-removing fixture mounted on the seven-axis casting system. The holding furnace 24, the servo-driven gravity casting machine 22, the cooling fixture 5, and the turnover fixture 6 are respectively arranged at intervals along the circumference of the first robot 21. The mixer 3 is used to stir the molten aluminum in the holding furnace 24, the cooling fixture 5 is used to cool the product, and the turnover fixture 6 is used to temporarily store the product. The sand-falling cutting assembly 14 includes a second robot 71, a cutting and handling fixture, a band saw 72, a sand-hammering fixture, a hammering station 73, a vibrating screen 74, and a storage cart 75.The cutting and handling fixture is installed on the second robot 71, and the sand-hammering fixture is installed on the hammering station 73. The band saw 72, the hammering station 73, the vibrating screen 74, and the cooling fixture 5 are respectively arranged at intervals along the circumference of the second robot 71. The band saw 72 is used to cut off the gating gate of the product, the hammering station 73 is used to crush the molding sand inside the product, and the vibrating screen 74 is used to shake out the crushed molding sand inside the product. In this embodiment, the sand-falling cutting zone 12 is located between the two casting cooling zones 11, that is, the two casting cooling zones 11 share one sand-falling cutting zone 12. The first robot 21, the servo-driven gravity casting machine 22, the holding furnace 24, the casting seven-axis, the second robot 71, the band saw 72, the hammering station 73, and the vibrating screen 74 are existing technologies and can all be purchased from the market. For specific details, refer to Chinese Patent CN221109875U. The casting seven-axis is installed on the first robot 21. One end of the casting seven-axis is equipped with a water ladle that can rotate to scoop molten aluminum, while the other end is equipped with the casting clamp. The hammering station 73 is specifically referenced in Chinese Patent CN221018630U, and the vibrating screen 74 is specifically referenced in Chinese Patent CN222402207U. The casting mold is customized according to the product. The servo-driven tilting gravity casting machine 22 has a platform operating area on its outer side. During operation, the worker places molding sand into the casting mold in the platform operating area, and then the first robot 21 scoops molten aluminum from the holding furnace 24 via the casting seven-axis and pours it into the mold. In the casting mold, the mixer 3 helps mix the molten aluminum with other elements in the holding furnace 24. Then, the servo-driven gravity casting machine 22 rotates 90° and waits for the product to form. After the product is formed, the first robot 21 uses the casting seven-axis to drive the casting fixture to remove the product and place it on the cooling fixture 5. The cooling fixture 5 sprays water to cool the product's inner cavity. After cooling, the second robot 71 uses a cutting and handling fixture to remove the product from the cooling fixture 5 and, with the assistance of the band saw 72, cuts off its gating and riser. The second robot 71 places the cut product into the hammering fixture using a cutting and handling clamp. The hammering station 73 operates to crush the molding sand inside the product. Then, the second robot 71 places the hammered product into a vibrating screen 74 using a cutting and handling clamp. The vibrating screen 74 operates to shake out the crushed molding sand inside the product. After the operation, the worker takes out the product, checks and marks it, and finally puts it into the storage car 75. Furthermore, the turnover fixture 6 is set up to temporarily store the product, which can prevent the product from being unable to continue production and causing material blockage when the casting cooling component 13 is damaged or under repair.This invention places the sand-falling cutting zone 12 between two casting cooling zones 11, with the two casting cooling zones 11 sharing a single sand-falling cutting zone 12. This compact and rational layout greatly optimizes the space utilization of the production site, enabling efficient completion of the entire production process of the motor housing from casting to sand-falling, reducing unnecessary space waste and lowering the company's site costs. This production line integrates multiple functional devices into one unit, with clear collaborative working relationships between the devices and a rational layout. On the one hand, this integrated design reduces the connection and transmission links between devices, lowering the probability of equipment failure. On the other hand, when one device fails, other devices can still continue to operate part of the production process, and turnover fixtures are provided for temporary product storage. This system effectively avoids material blockages caused by equipment malfunctions and repairs, reducing losses due to production stoppages. Furthermore, the high degree of automation and seamless integration of all stages minimizes waiting time and operational errors associated with manual operation, further improving production efficiency. The absence of overlap between manual operation and equipment work areas significantly reduces direct human involvement in demanding, high-temperature, and hazardous tasks, enhancing production line safety. Automated operation also keeps workers away from harsh working environments such as high temperatures and dust, reducing health risks from prolonged exposure to these harmful factors and providing safer, more comfortable working conditions that contribute to increased worker motivation and efficiency.

The limit switches 35 are electrically connected to the second drive unit 38. Each casting assembly 14 is equipped with two holding furnaces 24. Because the stirring process takes time, the two holding furnaces 24 are used alternately. When the other holding furnace 24 needs to be stirred, the second drive unit 38 drives the lifting seat 33 to move upward, so that the stirring rack is taken out from the original holding furnace 24. Then the first drive unit 37 drives the rotating seat 32 to rotate, so that the stirring rack swings above the other holding furnace 24. Then the second drive unit 38 drives the lifting seat 33 to move downward, and the limit switches 35 assist in positioning. Finally, the third drive unit 39 drives the stirring shaft 36 to rotate, so that the stirring rack rotates to stir the aluminum liquid.

During operation, the output ends of the first drive unit 45 extend and retract synchronously, so that the two first clamping plates 42 move in the clearance groove 411, so that the two first clamping plates 42 move closer to each other or further away from each other. Under the action of the first mating arc surface 431 and the second mating arc surface 432 of the first clamping toe 43 and the third mating arc surface 441 of the second clamping toe 44, the casting part removal fixture can firmly clamp the product.
