Problems solved by technology
[0003] During the processing of the sealing ring, there will be rubber edges on the inner and outer rings, and the rubber edges may affect the entire sealing effect of the sealing ring, so the sealing ring needs to be trimmed, and the conventional manual trimming is not only low in quality, but also labor-intensive. The strength is high, and the efficiency is still low. Although the low-temperature freezing deburring has a good trimming effect, the deburring effect on the inner ring is poor. The invention clarifies a device that can solve the above problems

The invention discloses a grinding and trimming device for an O-shaped sealing ring of a hydraulic valve. A positioning platform for positioning the sealing ring is slidably connected in the chamber, and a first spring is fixedly connected between the positioning platform and the lower surface of the spring chamber, and a first cavity is provided inside the base, and the The first cavity is provided with a first bevel gear fixed on the placement table, which can fully automatically realize the synchronous grinding and trimming effect on the inner ring and outer ring of the sealing ring, so that the grinding efficiency can be better, At the same time, the mechanical fixed grinding makes the grinding quality of the sealing ring more stable, the defective rate is low, and the whole operation only needs to place and remove the sealing ring, the operation is very simple, the labor intensity is low, and the use is convenient. The structure is simple and worth popularizing.
Description
technical field [0001] The invention relates to the technical field related to hydraulic valves, in particular to a grinding and trimming device for an O-ring of a hydraulic valve. Background technique [0002] The hydraulic valve O-ring is a very important part of the hydraulic valve, which plays a sealing role; [0003] During the processing of the sealing ring, there will be rubber edges on the inner and outer rings, and the rubber edges may affect the entire sealing effect of the sealing ring, so the sealing ring needs to be trimmed, and the conventional manual trimming is not only low in quality and labor-intensive. The strength is high, and the efficiency is still low. Although the low-temperature freezing deburring has a good deburring effect, the deburring effect on the inner ring is poor. The invention clarifies a device that can solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a grinding and trimming ...
