Description

Technical Field

[0001] The invention belongs to the technical field of sealing ring processing, and in particular relates to a surface treatment device for sealing ring processing. Background Art

[0002] A sealing ring is a ring-shaped part used to prevent fluid or gas leakage. Depending on its application and environmental conditions, the sealing ring is made of different materials, including hard materials and soft materials. Hard sealing rings are usually made of rigid materials such as metal or plastic, such as aluminum, copper, steel, polytetrafluoroethylene (PTFE), etc. These materials are characterized by high temperature resistance, chemical corrosion resistance, wear resistance, etc., and are suitable for sealing requirements that require long-term stability and strength. Hard sealing rings are generally used for static sealing or occasions with extremely high sealing precision requirements; soft sealing rings are generally made of elastic materials such as rubber, silicone rubber, nitrile rubber, etc., and are characterized by good sealing elasticity and deformability, and are suitable for dynamic sealing and some environments that require sealing performance. Soft sealing rings can better adapt to uneven surfaces or moving parts. Sealing rings are widely used in various industrial fields and equipment, such as automobile engines, hydraulic systems, pipeline connections, valves, pumps, and rotating or moving parts in various mechanical devices.

[0003] In the production process of sealing rings, it is usually necessary to process their surfaces. Surface treatment usually includes coating or grinding to improve their corrosion resistance and wear resistance. There are usually two ways to grind hard sealing rings with larger diameters. One is to manually grind the sealing rings with sandpaper. This grinding method is inefficient, but flexible to operate and can accurately grind the sealing rings in all aspects. The other is to grind with mechanical equipment. The sealing ring is fixed with a rotating fixture, and then the outer ring, inner ring, top and bottom of the sealing ring are grinded with the grinding wheel on the equipment. Although the grinding efficiency is high, the contact surfaces of the outer ring and inner ring of the sealing ring with the top and bottom are usually arc surfaces, but the existing mechanical equipment cannot fully grind the arc surfaces, resulting in incomplete surface grinding of the sealing ring, which in turn affects the processing quality.

After the sealing ring body 9 is fixed, it needs to be polished, and the third motor 805 is started, so that the third motor 805 drives the bidirectional screw rod 803 to rotate through the output shaft, and then drives the two nuts The seats 804 move toward each other, which drives the two sandpapers 814 to move toward each other, respectively fitting with the outer ring and the inner ring of the sealing ring body 9, and then starting the two fourth motors 810, so that the fourth motors 810 drive the connected drive shaft 808 to rotate through the output shaft rotation, and then drive the connected synchronous wheel 809 to rotate, and cooperate with another synchronous wheel 809 and the tensioning wheel 812 to drive the sleeved sandpaper 814 transmission, and the two sandpapers 814 drive to grind the outer ring and the inner ring of the sealing ring body 9.
