A grooving knife 54 is installed on the output shaft of the motor 53, and the grooving knife 54 is located in the strip hole 4.

[0033] The correction mechanism includes a rotating shaft 61, a groove plate 62, a sliding frame 63, a roller 64, a gear 65 and a rack 66.

[0035] Embodiment 2: Based on embodiment 1, Figure 6-Figure 10As shown, a pressing mechanism is also included, which is arranged on the round shell 2 and the groove plate 62. The pressing mechanism is used to press the piston ring 3. The pressing mechanism includes a pressing frame 71, a torsion spring 72, a ball 73, a fixing frame 74, a sliding rod 75 and an arc-shaped driving frame 76. Two square holes 701 are opened on the round shell 2. The two square holes 701 are symmetrically arranged. A pressing frame 71 is rotatably installed in each of the two square holes 701. Two torsion springs 72 are arranged between the pressing frame 71 on the same side and the square hole 701 on the same side. The two torsion springs 72 on the same pressing frame 71 are symmetrically arranged. One end of the torsion spring 72 is connected to the pressing frame 71, and the other end of the torsion spring 72 is connected to the On the wall of the hole 701 above the pressing frame 71, a number of balls 73 are evenly spaced on the two pressing frames 71, a fixing frame 74 is respectively installed on the two side surfaces inside the circular shell 2, and the two fixing frames 74 are symmetrically arranged. A sliding rod 75 is slidably installed on the two fixing frames 74, and the sliding rod 75 will slide horizontally along the fixing frame 74. The two sliding rods 75 are symmetrically arranged, and two arc-shaped driving frames 76 are installed on the groove plate 62. Each arc-shaped driving frame 76 is composed of an inner inclined portion and an arc-shaped portion. One end of the two sliding rods 75 is in contact with one side of the pressing frame 71, and the other ends of the two sliding rods 75 are respectively located in the inner inclined portions of the two arc-shaped driving frames 76.

[0036] The length of the inner oblique portions on the two arc-shaped driving frames 76 is shorter than the length of the outer oblique portions of the three guide grooves opened in the groove plate 62 .

[0037] It also includes a clamping mechanism 8, which is arranged on the strip hole 4 and the electric slider 52. The clamping mechanism 8 is used to clamp the processed part of the piston ring 3. The clamping mechanism 8 includes a fixed arc block 81, a slide rod 82, a sliding arc block 83 and a reset spring 84. A fixed arc block 81 is respectively installed on both sides of the strip hole 4, and the two fixed arc blocks 81 are symmetrically arranged. A slide rod 82 is installed on the two electric sliders 52. A sliding arc block 83 is slidably provided on the two slide rods 82. The sliding arc block 83 will move along the slide rod 82. The two sliding arc blocks 83 are symmetrically arranged. The two sliding arc blocks 83 are respectively slidably connected to the two sides of the strip hole 4, and a reset spring 84 is respectively connected between one side of the two sliding arc blocks 83 and the two slide rods 82.

[0038] The piston ring 3 is placed between two fixed arc blocks 81 and two sliding arc blocks 83 .

[0039] The rotation of the groove plate 62 drives the two arc-shaped driving frames 76 to rotate. The inner oblique parts on the two arc-shaped driving frames 76 drive the two sliding rods 75 to move along the fixing frames 74 in the direction away from each other. The outer ends of the two sliding rods 75 push the lower parts of the two pressing frames 71 to swing upward in the direction away from each other, and the upper parts of the two pressing frames 71 swing downward in the direction close to each other. The two torsion springs 72 twist accordingly, and the two pressing frames 71 press the piston ring 3, so that the bottom of the piston ring 3 can be close to the outer top of the round shell 2, thereby correcting and fixing the vertical direction of the piston ring 3, and being able to more fully correct and fix the piston ring, so that the part to be processed of the piston ring 3 can be more accurately aligned with the grooving cutter 54, thereby improving the accuracy of the grooving of the piston ring 3. Since the length of the inner oblique parts on the two arc-shaped driving frames 76 is shorter than the length of the outer oblique parts of the three guide grooves opened in the groove plate 62, the two The first pressing frame 71 presses the piston ring 3 first, and the roller 64 corrects and fixes the piston ring 3. In the process of the roller 64 correcting the piston ring 3, the piston ring 3 can move relatively smoothly under the action of the ball 73, and after the two sliding rods 75 are located at the arcuate parts on the two arc driving frames 76, the two sliding rods 75 no longer move in the direction away from each other; after the piston ring 3 is grooved, the groove plate 62 rotates in the opposite direction to drive the two arc driving frames 76 to rotate in the opposite direction, and the inner oblique parts on the two arc driving frames 76 drive the two sliding rods 75 to move along the fixing frame 74 in the direction of approaching each other, and the outer ends of the two sliding rods 75 no longer support the lower parts of the two pressing frames 71. Under the action of the torsion spring 72, the upper parts of the two pressing frames 71 swing upward in the direction away from each other, and the two pressing frames 71 release the pressure on the piston ring 3, and the operator can take out the piston ring 3 with the open groove cut.

[0040] The operator places the piston ring 3 between the two fixed arc blocks 81 and the two sliding arc blocks 83. The outer side wall of the corrected piston ring 3 contacts the side surfaces of the two fixed arc blocks 81. The two electric sliders 52 move to drive the two slide bars 82, the two sliding arc blocks 83 and the two return springs 84 to move. After the two sliding arc blocks 83 contact the inner side wall of the piston ring 3, the two fixed arc blocks 81 and the two sliding arc blocks 83 can clamp the position of the piston ring 3 that needs to be grooved. When the two electric sliders 52 drive the motor 53 and the groove cutting knife 54 to groove the piston ring 3, the two sliding arc blocks 83 no longer move, and the two electric sliders 52 drive the slide bar 82 to continue to move, and the return spring 84 is stretched accordingly. The two fixed arc blocks 81 and the two sliding arc blocks 83 can clamp the position of the piston ring 3 that needs to be grooved, thereby avoiding deformation of the grooved position of the piston ring 3 during the groove cutting process and improving the quality of the piston ring 3 after processing.

[0041] Embodiment 3: Based on embodiment 2, Figure 9-11As shown, a rubber strip 9 is also included. A rubber strip 9 is installed on one side of each of the two sliding arc blocks 83 , and a rubber strip 9 is also installed on one side of each of the two fixed arc blocks 81 .

[0042] It also includes a protrusion 10 and a material ejection rack 11. A material ejection rack 11 is slidably provided on one side of the round shell 2. The material ejection rack 11 slides up and down along the round shell 2. A protrusion 10 is installed on the groove plate 62, and the protrusion 10 contacts one side of the material ejection rack 11.

[0043] Under the action of the rubber strip 9, when the piston ring 3 is clamped, the probability of the piston ring 3 being scratched can be reduced.

[0044] Initially, the protrusion 10 presses against the lower part of the ejecting frame 11. When the operator puts in the piston ring 3, one side of the piston ring 3 contacts the upper part of the ejecting frame 11, and one side of the piston ring 3 is lifted up by the ejecting frame 11. The rotation of the groove plate 62 drives the protrusion 10 to rotate. After the protrusion 10 is separated from the lower part of the ejecting frame 11, the ejecting frame 11 moves downward under the action of gravity, and the lower part of the ejecting frame 11 contacts the groove plate 62. After the ejecting frame 11 moves downward, it is embedded in the round shell 2, and the bottom of the piston ring 3 can contact the top of the round shell 2, thereby not affecting the processing of the piston ring 3; after the processing of the piston ring 3 is completed, the groove plate 62 drives the protrusion 10 to rotate in the opposite direction and reset, and the protrusion 10 lifts up the ejecting frame 11 again, and one side of the piston ring 3 is lifted up by the ejecting frame 11, so that the operator can take out the processed piston ring 3 conveniently.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
