Description

Retaining ring notch combination frock Technical Field The utility model relates to the technical field of sealing elements, in particular to a check ring notch tool. Background The polytetrafluoroethylene check ring is a sealing element material with high chemical resistance and high temperature stability, and is widely applied to the sealing field of various industries. Because of the unique corrosion resistance and excellent high temperature resistance, the polytetrafluoroethylene check ring is widely focused and applied in the fields of chemical industry, aviation, medical treatment, electronics, energy sources and the like, the notch of the polytetrafluoroethylene check ring is not a damage, but is a necessary design requirement, because the polytetrafluoroethylene check ring has certain flexibility and elasticity, if the polytetrafluoroethylene check ring is not provided with the notch, the polytetrafluoroethylene check ring can be extruded and deformed due to the overlarge diameter of the check ring during installation, and the installation quality and the service life are further reduced. But the prior art lacks specialized tooling for the retainer ring cutouts. If the incision is performed manually, the incision flatness is not high, and the incision quality is low. The utility model discloses a fluoroplastic retainer ring notch tool, which belongs to the field of aviation equipment maintenance and solves the problems that a notch angle of a fluoroplastic retainer ring is difficult to guarantee, manufacturing difficulty is high and working efficiency is low in a cutting process. The tool comprises a cylindrical positioning block, a cylindrical mounting block and a positioning structure. According to the utility model, the circular arc angle of the notch is manually controlled by replacing the notch guide groove of the check ring, and an operator uses the single-sided blade to cut along the guide groove, so that the cutting quality can be ensured, the working flow is simplified, and the primary operator can independently complete the cutting work of the notch of the check ring. However, although the notch tool can fix the retainer ring, the notch tool cannot be fixed, and a quick cutting mode of linear cutting is adopted after the retainer ring is in a stable state, so that the notch efficiency and the notch quality are affected.
