Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to metal casting processing equipment. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then obtaining a part or blank after it cools and solidifies. After the casting is taken out from the cooled mold, it has gates, risers, metal burrs, and seams. Sand castings are still adhered to sand, so they must go through a cleaning process to ensure that the workpiece surface is smooth and free of impurities.

[0003] Currently, most grinding methods use grinding machines. This surface treatment method is not only time-consuming and labor-intensive, but also often cannot effectively treat the crevices of special-shaped castings. When sandblasting is used for grinding, workers are required to wear protective gloves and reach into the sandblasting machine to sandblast the workpiece. This method requires workers to operate for a long time, which is also time-consuming and labor-intensive, affecting work efficiency. Utility Model Content

The lower end of the inverted conical cover is provided with a discharge port, and the discharge port is fixedly connected with a mounting base through three connecting rods. The upper surface of the mounting base is rotatably connected with a diagonal support rod, and the upper end of the diagonal support rod is rotatably connected with a sleeve. A movable rod is sleeved inside the sleeve, and a plug-in assembly for fixing the position of the movable rod is provided at the end of the sleeve. A gear transmission part is provided at the end of the sleeve for rotating with the diagonal support rod, and a clamping assembly is provided at the end of the movable rod for fixing the casting.

[0008] When using the above-mentioned metal casting processing equipment, quartz sand blasting material is added to the sandblasting hopper, and the blower is turned on to blow air into the vertical pipe. The casting is fixed to the end of the movable rod through the clamping assembly, and then the position of the movable rod is fixed by the plug-in assembly, and the diagonal support rod is driven to rotate. As the diagonal support rod rotates, the sleeve and the movable rod are driven to rotate together through the gear transmission part. At this time, the clamped workpiece also rotates with it. Then, the switch at the lower end of the sandblasting hopper is turned on to make the sandblasting material fall. After being accelerated by the high-speed wind in the vertical pipe, the sandblasting material hits the continuously turning surface of the casting to complete the surface treatment.

[0009] Preferably, a motor for driving the diagonal support rod to rotate slowly is fixedly mounted on the bottom surface of the mounting base, and the diameter of the motor is smaller than the diameter of the mounting base.

[0014] Preferably, a magnetic plate is fixedly connected to the take-and-put port, and the magnetic plate is magnetically connected to the iron protective door.

[0015] The beneficial effects are:

[0016] By fixing the casting at the end of the movable rod through a clamping assembly, and then fixing the position of the movable rod through a plug-in assembly, and driving the diagonal support rod to rotate, as the diagonal support rod rotates, the sleeve and the movable rod are driven to rotate together through the gear transmission part. At this time, the clamped workpiece also rotates with it, and then the switch at the lower end of the sandblasting hopper is turned on to make the sandblasting material fall. After being accelerated by the high-speed wind in the vertical pipe, the sandblasting material hits the surface of the continuously turning casting, avoiding the staff from operating for a long time, realizing fully automatic and comprehensive sandblasting processing, and improving work efficiency.
