Embodiment Construction
[0012] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0013] Such as Figure 1 to Figure 3 As shown, the method for repairing the groove of the special-shaped sealing ring of the automobile comprises using a groove repairing tool of the special-shaped sealing ring of the automobile to process six axial grooves on the special-shaped sealing ring of the automobile.
[0014] figure 1 , figure 2 The automobile special-shaped sealing ring shown includes an annular ring body 1, and the cross section of the ring body 1 is circular. The ring body 1 is provided with radial grooves 3 along the radial direction. There are at least two radial grooves 3, here are ten, and they are evenly distributed along the center of the ring body 1. The opening of the radial grooves 3 makes the sealing ring The parts that are easily damaged during installation reduce the chance of stress concentration, which is convenient f...

The invention discloses a groove repairing method of an automotive special-shaped sealing ring. A plurality of grooves which are formed in the automotive special-shaped sealing ring are machined through a groove repairing cutting tool; a circle of radial grooves are formed in a ring body along the radial direction; the at least two radial grooves are uniformly distributed along the center of the ring body; four or six axial grooves are uniformly formed in the ring body along the axial direction; the groove repairing cutting tool comprises a vertical rotating shaft, a cross rod, an upper cutter holder and a lower cutter holder; at least two forming cutters are uniformly arranged at the concaved position of the upper cutter holder and at least two forming cutters are uniformly arranged at the concaved position of the lower cutter holder; the machining process of groove repairing method comprises placing the automotive special-shaped sealing ring between tool bits of the corresponding forming cutters of the upper cutter holder and the lower cutter holder, fastening the upper cutter holder and the lower cutter holder through screws, rotating the rotating shaft for a circle and achieving the groove repairing, wherein the groove repairing is to be performed on the automotive special-shaped sealing ring. According to the groove repairing method of the automotive special-shaped sealing ring, the automotive special-shaped sealing ring which is convenient to install, not easy to damage and long in service life can be accurately and efficiently machined.
Description
technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a sealing ring of special-shaped rubber used in automobiles. Background technique [0002] The existing method for repairing grooves of special-shaped sealing rings for automobiles, such as a rubber sealing ring installed on the inner wall of a brake hydraulic oil cylinder, has an annular ring body whose cross-section is circular. Since this kind of sealing ring is required to have high elasticity, compression deformation and wear resistance, the wall of the ring body is thicker, which is extremely laborious to install and easy to damage, and it is constantly squeezed during use. The amount of deformation is also very limited, resulting in the excessive concentration of stress in some positions and easy damage, and the service life is short. Therefore, it is necessary to design a special-shaped sealing ring and its processing method, which can be processed with ...
