For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] like Figure 1-2 As shown, the utility model provides one specific embodiment of a sealing ring end face groove processing device, including two active pressure wheels 1 and two driven pressure wheels 4. The active pressure wheels 1 are driven to rotate by a rotation drive device 2. The rotation drive device 2 is a conventional motor or the like driving a reduction box, which is used to drive the two active pressure wheels 1 to rotate synchronously. This is a prior art and will not be described in detail here. What is important is that the active pressure wheels 1 rotate horizontally, and the two active pressure wheels 1 are on the same horizontal plane.

[0028] The driven pressure wheel 4 is driven to move by the horizontal driving device 5, and at least two driven pressure wheels 4 are matched one by one with the active pressure wheel 1 under the drive of the horizontal driving device 5. The two driven pressure wheels 4 are installed on the horizontal driving device 5, and the horizontal driving device 5 is a conventional device that is driven horizontally by a motor or the like in cooperation with a worm gear. This is a prior art and will not be repeated here. What is important is that the two driven pressure wheels 4 are matched one by one with the two active pressure wheels 1. When the two driven pressure wheels 4 move toward the active pressure wheel 1, the two driven pressure wheels 4 can press the sealing ring against the active pressure wheel 1 for extrusion. The two active pressure wheels 1 are provided with a first fixed groove 3, and the two driven pressure wheels 4 are provided with a second fixed groove 6, and the second fixed groove 6 is at the same horizontal height as the first fixed groove 3. The longitudinal section shape of the first fixed groove 3 is a trapezoid, and the outer opening is large and the inner opening is small; similarly, the longitudinal section shape of the second fixed groove 6 is a trapezoid, and the outer opening is large and the inner opening is small. A section of the sealing ring is squeezed between the active pressure wheel 1 and the driven pressure wheel 4 and is stuck in the first fixed groove 3 and the second fixed groove 6. The rotation of the active pressure wheel 1 drives the sealing ring to rotate as well.

[0029] In order to increase the stability of the sealing ring, a supporting device 9 for supporting the sealing ring is also installed under the sealing ring. The supporting device 9 includes three rotating rollers 901. The three rotating rollers 901 are on the same horizontal plane and are lower than the horizontal plane where the first fixed groove 3 and the second fixed groove 6 are located. When the sealing ring is squeezed and rotated by the active pressure wheel 1 and the driven pressure wheel 4, it is on the upper part of the rotating roller 901, which supports the lower end surface of the sealing ring. Each rotating roller 901 is arranged along the radial direction of the sealing ring to facilitate the rotation of the sealing ring on the rotating roller 901. The rotating drive device 2, the horizontal drive device 5 and the supporting device 9 are all installed with a support frame 10 for support, so that they can be fixed on the ground with the support frame 10.

[0030] The cutter head 7 for end surface processing is mounted on a dual-axis drive device 8. In this specific embodiment, the lower end longitudinal section of the cutter head 7 is V-shaped, which can be used to process V-grooves. The dual-axis drive device 8 is an existing device that can drive the cutter head 7 to move up and down and forward and backward. This is a prior art and will not be described in detail here. It is important that one of the movement directions of the dual-axis drive device 8 is up and down movement, and the other movement direction is horizontal movement along the radius of the sealing ring. Specifically, the cutter head 7 is between two active pressure wheels 1 and a driven pressure wheel 4 that match each other, and one of the rotating rollers 901 is located between the two active pressure wheels 1 and the driven pressure wheel 4. The rotating roller 901 located between the two active pressure wheels 1 and the driven pressure wheel 4 that match each other corresponds to the cutter head 7 up and down, so that the support force of the sealing ring at the pressing position of the cutter head 7 is stronger.

[0031] When in use, the sealing ring is squeezed and fixed on the active dynamic pressure wheel by the driven pressure wheel 4, and is supported by the supporting device 9 formed by three rotating rollers 901. Under the rotation of the active pressure wheel 1, the sealing ring rotates. At this time, the cutter head 7 moves downward to process a circle of V grooves on the upper end surface of the sealing ring. After moving upward, the cutter head 7 moves horizontally along the radial direction of the sealing ring for a section, and then the cutter head 7 continues to move downward to complete another circle of V groove processing. Moreover, after processing the last circle of V grooves, the cutter head 7 moves downward again and moves horizontally to complete the processing of the outermost circle of the sealing ring. (Refer to Figure 3 ).
