Description

Technical Field

[0001] The utility model belongs to the technical field of bearing steel ball production equipment, in particular to a bearing steel ball precision polishing and chip removal equipment. Background Art

[0002] Steel balls are common parts in our daily work (including life). The quality of steel balls determines the life of bearings. It also has a great impact on the performance and life of mechanical equipment and vehicles (including cars, electric vehicles, and bicycles). Steel balls are divided into ground steel balls, forged steel balls, and cast steel balls according to the production and processing technology.

[0003] When processing steel balls, in order to improve the smoothness of the steel ball surface, the surface of the steel balls needs to be polished. Application No. CN202220598384.1 discloses a steel ball surface polishing device for steel ball production. The polishing device places the steel ball to be polished in the second polishing groove, and places two limit rings on the outside of the turntable respectively, and the steel ball is located between the first polishing groove and the second polishing groove. The two limit rings are connected to each other by nuts and screws according to the size of the steel balls. At the same time, the screws are installed in the screw holes and the through grooves to limit the limit rings. The motor is connected to the power supply, and the turntable is driven by the motor to rotate, so that the steel ball is polished in the first polishing groove and the second polishing groove. It is found in use that the device is more troublesome for putting in the steel balls and taking them out after polishing. The two limit rings need to be frequently removed and installed, which seriously affects the production efficiency of the steel balls. Moreover, the polishing powder in the first polishing groove and the second polishing groove cannot be well removed during polishing, which is easy to affect the polishing effect of the steel balls.

[0004] Based on the deficiencies in the prior art, the utility model discloses a precision polishing and chip removal device for bearing steel balls. By arranging a ball inlet and a ball outlet on an outer polishing ring and arranging a dust suction pipe at the ball outlet, it is convenient to put in and take out the steel balls and to remove the powder and chips inside the inner polishing chamber during polishing. There is no need to frequently disassemble the outer polishing ring, thereby improving the polishing efficiency and quality. Utility Model Content
