High-precision polishing equipment for die-casting workpiece and polishing method thereof

Abstract

The invention discloses high-precision polishing equipment for a die-casting workpiece and a polishing method thereof. A polishing mechanism is arranged between a first supporting platform and a second supporting platform, a second pneumatic cylinder is driven, a supporting plate can be driven to rotate, the tensioning degree of a polishing belt is further adjusted, a first pneumatic cylinder is driven, the position of the polishing belt can be adjusted, the polishing position of the polishing belt on a workpiece is further adjusted, the polishing position and the polishing degree can be conveniently adjusted, the adjustment is convenient, and the polishing precision is high when the workpiece is polished. According to the equipment and the method, the upper end of a third supporting platform is provided with a rotating device and a clamping device, when the polishing equipment is used, a third motor is driven to drive the die-casting workpiece to rotate for one circle to polish the workpiece, a second motor is driven, a rotating shaft is rotated to drive a bearing plate to rotate so as to drive the die-casting workpiece for revolution, a next die-casting workpiece can be polishedconveniently, polishing is finished through the rotation when the polishing equipment is used, replacement is finished through the revolution, equipment halt is avoided, and the working efficiency isimproved.

Description

technical field [0001] The invention relates to the processing field of die-casting workpieces, in particular to high-precision polishing equipment and a polishing method for die-casting workpieces. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die-casting machine, and passes through the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are usually called die castings. [0003] After the die-casting is completed, there are many particles on the surface of the workpiece, and the surface is rough and needs to be polished. Existing grinding and polishing equipment has low precision during polishing. After a long period of polishing, the polishing belt will easily lead to changes in ...

AI Technical Summary

Problems solved by technology

Existing grinding and polishing equipment has low precision during polishing. After a long period of polishing, the polishing belt will easily lead to changes in the precision of polishing after being worn out. The long-term work of the polishing belt will also easily lead to insufficient tension and poor polishing effect. Difference

[0004] At the same time, during polishing, the workpiece needs to be clamped, and the clamping effect is poor. At the same time, after the polishing is completed, it needs to be disassembled and replaced, which is inconvenient to operate, causing the equipment to stop and affect the work efficiency.
