[0023] like Figure 4As shown, the connecting frame 2 is installed on the lower surface of the support plate 1. A first return spring 3 is installed inside the connecting frame 2. A movable block 4 is slidably connected inside the connecting frame 2. The top of the first return spring 3 is installed on the lower surface of the movable block 4. A movable disk 5 is installed on the inner side of the movable block 4. The movable disk 5 passes through the support plate 1. A movable frame 6 is installed on the outer side of the movable block 4. A first connecting groove is opened on the outer side of the connecting frame 2. The first connecting groove is slidably connected to the movable frame 6. The movable frame 6 is slidably connected inside the connecting frame 2. A fixing plate 7 is installed on the inner side of the connecting frame 2. An inclined block 8 is installed on the upper surface of the fixing plate 7. The inclination of the inclined block 8 gradually decreases from the outside to the inside. A second return spring 9 is installed inside the movable disk 5. A connecting block 10 is slidably connected inside the movable disk 5. The outer end of the second return spring 9 is installed on the side of the connecting block 10. An auxiliary block 11 is installed on the upper surface of the connecting block 10. A contact block 12 is installed on the outer side of the auxiliary block 11. The contact block 12 is a rubber block. An adjustment mechanism is provided on the lower surface of the connecting block 10.

[0024] like Figure 4 As shown, the adjustment mechanism includes a connecting rod 13, an inclined rod 14, and an auxiliary wheel 15. The connecting rod 13 is installed on the lower surface of the connecting block 10 and is slidably connected to the moving disk 5. The moving disk 5 has a second connecting groove inside, which is slidably connected to the connecting rod 13. The inclined rod 14 is installed at the bottom of the connecting rod 13 and is inclined at the center of the moving disk 5. An auxiliary wheel 15 is installed at the bottom of the inclined rod 14, and the inclined angle of the auxiliary wheel 15 is the same as that of the inclined rod 14.

[0025] like Figure 3 As shown, a mounting plate 16 is installed on the upper surface of the support plate 1. A connecting pipe 17 is installed on the outer side of the mounting plate 16. A moving rod 18 passes through the inside of the connecting pipe 17. The outer surface of the moving rod 18 passes through the inside of the mounting plate 16. A connecting pin 19 is threaded through the outer surface of the connecting pipe 17. One end of the connecting pin 19, threaded into the connecting pipe 17, abuts against the moving rod 18. An auxiliary plate 20 is installed on the inner end of the moving rod 18. A contact frame 21 is installed on the inner side of the auxiliary plate 20. A reinforcing plate is installed on the side of the auxiliary plate 20. The reinforcing plate is fixedly connected to the outer surface of the contact frame 21. A ball bearing 22 is rotatably connected inside the contact frame 21. Figure 1 As shown, a repair equipment body 23 is installed on the upper surface of the support plate 1. The repair equipment body 23 is a laser repair machine in the prior art. The laser repair machine repairs the valve seat non-contactly using a laser beam. During the reciprocating movement of the laser beam, defects on the valve seat sealing surface are eliminated. The repair equipment body 23 requires an external power supply. A support frame 24 is installed on the lower surface of the support plate 1.

[0026] In this embodiment, the valve seat is placed on the upper surface of the movable disk 5, so that the contact block 12 enters the valve seat and is fixed thereon. The movable rod 18 is moved inward along the connecting pipe 17. The inward movement of the movable rod 18 causes the auxiliary plate 20 to move inward. The inward movement of the auxiliary plate 20 causes the contact frame 21 to move inward. The inward movement of the contact frame 21 causes the ball 22 to move inward. The ball 22 moves inward and contacts the outer surface of the valve seat. Then, the connecting pin 19 is rotated clockwise to press against the movable rod 18.

[0027] After the repair equipment body 23 repairs the sealing surface of the valve seat, after the repair is completed, the operating moving frame 6 drives the moving block 4 to move downward along the connecting frame 2. The moving block 4 moves downward and compresses the first reset spring 3. The moving block 4 moves downward and drives the moving disk 5 to move downward. The moving disk 5 moves downward and drives the connecting block 10 to move downward. The connecting block 10 moves downward and drives the auxiliary block 11 to move downward. The auxiliary block 11 moves downward and drives the contact block 12 to move downward. The connecting block 10 moves downward and drives the connecting rod 13 to move downward. The connecting rod 13 moves downward and drives the tilting rod 14 to move downward. The tilting rod 14 moves downward and drives the auxiliary wheel 15 to move downward.

[0028] When the auxiliary wheel 15 contacts the inclined block 8, the auxiliary wheel 15 rolls inward along the inclined block 8. The inward movement of the auxiliary wheel 15 drives the inclined rod 14 to move inward. The inward movement of the inclined rod 14 drives the connecting rod 13 to move inward. The inward movement of the connecting rod 13 drives the connecting block 10 to move inward. The inward movement of the connecting block 10 compresses the second return spring 9. The inward movement of the connecting block 10 drives the auxiliary block 11 to move inward. The inward movement of the auxiliary block 11 drives the contact block 12 to move inward, so that the contact block 12 gradually releases the valve seat.

[0029] The operator removes the repaired valve seat, places the valve seat to be repaired on the upper surface of the moving plate 5, releases the moving frame 6, causing the first return spring 3 and the second return spring 9 to spring back, resetting the moving plate 5 and the contact block 12 respectively, and then continues to repair the remaining valve seats through the repair equipment body 23.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
