Burr removing device for formed rubber sealing ring of petroleum machine

Abstract

The invention relates to the technical field of machining of petroleum machine parts, in particular to a burr removing device for a formed rubber sealing ring of a petroleum machine. The burr removing device comprises a base, a fixing unit and a grinding unit, wherein an annular groove is formed in the upper end of the base, the fixing unit is arranged in the annular groove, and the grinding unit is arranged on the fixing unit. The burr removing device can solve the following problems existing when burrs of rubber sealing rings are removed: most of traditional rubber sealing rings are manually trimmed, and workers cannot effectively fix the rubber sealing rings, so that the machining efficiency is influenced; existing freezing trimming equipment cannot effectively remove small burrs on the surface of a rubber sealing ring, thereby having limitation; the rubber sealing ring can be clamped and fixed in multiple directions, and therefore the stability of the rubber sealing ring can be improved; and according to the burr removing device, circumferential grinding treatment can be conducted on the rubber sealing ring through the grinding unit, chippings generated by grinding can be recycled, and resource waste can be avoided.

Description

technical field [0001] The invention relates to the technical field of processing petroleum machinery accessories, in particular to a device for removing burrs after molding of petroleum machinery rubber sealing rings. Background technique [0002] Petroleum machinery mainly refers to various machinery and equipment that need to be used in the process of oil extraction, storage, transportation, refining, etc. Petroleum machinery mainly includes mud pumps, oil drilling rigs, pumping units, oil exploration equipment and oil drilling equipment, of which mud The pump refers to the machine that transports flushing fluid such as mud or water into the borehole during the drilling process. Usually, in order to enhance the sealing performance of the mud pump, it is necessary to install a rubber sealing ring inside the mud pump. After the rubber sealing ring is formed, the rubber There will be burrs on the surface of the sealing ring, so it is necessary to remove the burrs on the surf...

AI Technical Summary

Problems solved by technology

[0003] At present, the rubber sealing ring mostly adopts the method of manual trimming and the method of trimming with freezing trimming equipment when removing the burr, but the following problems exist in the two trimming methods: 1. Because the texture of the rubber sealing ring is soft, Workers cannot effectively fix the rubber sealing ring, which makes the rubber sealing ring lack of stability, which affects the processing efficiency and poses a safety risk

[0004] The existing freezing trimming equipment uses liquid nitrogen to make the burr of the rubber sealing ring brittle at low temperature, and then beats the burr. Since this type of equipment is only suitable for removing large burrs on the surface of the rubber sealing ring, it cannot Smaller burrs are effectively removed, so there are limitations, and the debris from the removal of burrs cannot be recycled again, which easily causes waste of resources
