A vertical side plate 2 is provided on one side of the top of the base plate 1. The vertical side plate 2 is fixedly connected to the base plate 1, and the vertical side plate 2 is perpendicular to the base plate 1. The control base 3 is slidably connected to the top of the base plate 1, and the control base 3 is opposite to the vertical side plate 2. A positioning shaft 31 is provided on the top of the control base 3. When in use, the ratchet is sleeved on the outside of the positioning shaft 31. The positioning shaft 31 is controlled to rotate by the control base 3, which can drive the ratchet to rotate. A fixed plate 12 is provided on the top of the base plate 1. The fixed plate 12 is located on the side of the base plate 1 away from the vertical side plate 2. A threaded rod 13 is threadedly connected to the inner side of the fixed plate 12. One end of the threaded rod 13 is rotated with the control base 3. The control base 3 can be pushed and pulled by rotating the threaded rod 13, so as to adjust the position of the control base 3. A movable plate 4 is provided on one side of the vertical side plate 2, and the movable plate 4 is slidably connected to the vertical side plate 2. A movable rod 5 is rotated by a torsion spring at the bottom of one side of the movable plate 4. The end of the movable rod 5 away from the movable plate 4 is an inclined surface matching the shape of the ratchet tooth groove. The position of the movable rod 5 corresponds to the position of the positioning shaft 31. When the control base 3 moves toward the direction of the vertical side plate 2, the position of the ratchet can be determined by the movable rod 5. When one end of the movable rod 5 is aligned with one of the tooth grooves of the ratchet, the position of the ratchet can be positioned to ensure the accuracy of subsequent edging. A protrusion 51 is provided on one side of the movable rod 5. The protrusion 51 and the movable rod 5 The movable plate 4 is fixedly connected, the sensor 42 is located at the bottom of one side of the movable plate 4, and the position of the sensor 42 corresponds to the position of the protrusion 51. When the positioning shaft 31 drives the ratchet to rotate, it will drive the movable rod 5 to rotate to one side. As the next tooth groove is filled, the movable rod 5 will rotate and reset to align with the tooth groove, so that the protrusion 51 is reset and aligned with the sensor 42, so that the sensor 42 recognizes the protrusion 51. The hydraulic rod 43 is located at the bottom of the movable plate 4, and one end of the hydraulic rod 43 is fixedly connected to the top of the bottom plate 1. When the sensor 42 recognizes the protrusion 51 once, the hydraulic rod 43 will start to shrink. Since one end of the hydraulic rod 43 is fixed to the bottom plate 1, when the hydraulic rod 43 shrinks, the movable plate 4 will slide downward. A connection is provided on the top of one side of the movable plate 4. The connecting frame 44 is fixedly connected to the movable plate 4. A grinding wheel 6 is arranged on the inner side of the connecting frame 44. The grinding wheel 6 is a trapezoidal disc, and the bevel of the grinding wheel 6 matches the tooth groove of the ratchet. The grinding wheel 6 corresponds vertically to the position of the movable rod 5. Therefore, when the movable rod 5 corresponds to the tooth groove of the ratchet, the sliding of the movable plate 4 will drive the grinding wheel 6 to move down to grind one of the tooth grooves of the ratchet, thereby reducing the burrs in the tooth groove, ensuring the smoothness of the tooth groove, and improving the manufacturing accuracy of the ratchet. The rotating motor 441 is located on one side of the connecting frame 44. The grinding wheel 6 can be driven to rotate by the rotating motor 441. When the grinding wheel 6 contacts the ratchet, it can be polished by the rotation of the grinding wheel 6. The tooth groove of the ratchet can be polished by the grinding wheel 6.Since the inclined surface of the grinding wheel 6 matches the tooth groove shape of the ratchet wheel, the grinding of the grinding wheel 6 can not only reduce the burrs in the tooth groove and improve the smoothness of the tooth groove, but also calibrate the shape of the tooth groove, which is beneficial to improve the accuracy of the ratchet tooth groove and reduce errors. The position of the ratchet wheel and whether the ratchet tooth groove corresponds vertically to the grinding wheel 6 can be measured by the movable rod 5, which is beneficial to quickly locate the ratchet wheel and ensure the accuracy of edge grinding.

[0019] A slide groove 11 is provided on the top of the base plate 1, and the control base 3 is slidably connected to the slide groove 11; the sliding path of the control base 3 can be fixed by connecting the control base 3 with the slide groove 11, thereby preventing the control base 3 from deviating during movement.

[0020] A connection groove 21 is provided on one side of the vertical side plate 2, and the movable plate 4 is slidably connected to the connection groove 21; through the connection between the movable plate 4 and the connection groove 21, the movable plate 4 can only move up and down.

[0021] A connecting plate 32 is provided on one side of the control base 3, the threaded rod 13 is rotatably connected to the connecting plate 32, and an adjusting disk 131 is provided on the end of the threaded rod 13 away from the control base 3; when the position of the control base 3 is adjusted by rotating the threaded rod 13, one end of the threaded rod 13 will rotate on one side of the connecting plate 32, and the threaded rod 13 can be easily rotated by the adjusting disk 131.

[0022] Two connecting seats 41 are provided on one side of the movable plate 4, and the two connecting seats 41 correspond vertically. The movable rod 5 is rotated between the two connecting seats 41 by a torsion spring; when the movable rod 5 is aligned with the tooth groove of the ratchet wheel, the rotation of the ratchet wheel will drive the movable rod 5 to rotate to one side, and the torsion spring can drive the movable rod 5 to rotate and reset to align with the next tooth groove.

[0023] The fixing plate 12 is provided with a 121, and the threaded rod 13 is threadedly connected to 121; through the connection between the threaded rod 13 and 121, when the threaded rod 13 rotates, the distance between the control base 3 and the fixing plate 12 can be adjusted.

[0024] The working principle and use process of the utility model are as follows: when in use, the ratchet needs to be fixed to the outside of the positioning shaft 31 first, and then the position of the control base 3 is adjusted by rotating the threaded rod 13, and the ratchet will move accordingly. When one end of the movable rod 5 is in contact with one of the tooth grooves of the ratchet, the positioning of the ratchet can be completed. Then, the grinding wheel 6 is rotated by rotating the motor 441. At the same time, the sensor 42 is made to be in a recognizable state. Since the position of the protrusion 51 corresponds to the sensor 42, the sensor 42 will recognize the protrusion 51. When the sensor 42 recognizes the protrusion 51 once, the hydraulic rod 43 will start to retract. Since one end of the hydraulic rod 43 is fixed to the bottom plate 1, when the hydraulic rod 43 retracts, the movable plate 4 will The movable rod 5 is moved downwards, thereby driving the grinding wheel 6 to move downwards. Since the positions of the movable rod 5 and the grinding wheel 6 correspond vertically, the grinding wheel 6 will grind the teeth of the ratchet when it moves downwards. When the hydraulic rod 43 is retracted, it will automatically extend upwards, thereby causing the movable plate 4 to move upwards and reset. When the movable rod 5 is in contact with the polished teeth again, the ratchet is driven to rotate clockwise by controlling the base 3 and the positioning shaft 31. The rotation of the ratchet causes the movable rod 5 to rotate to one side, and the protrusion 51 is separated from the sensor 42. The torsion spring will drive the movable rod 5 to rotate and reset to contact the next teeth. At the same time, the protrusion 51 will contact the sensor 42 again, thereby causing the hydraulic rod 43 to retract downwards again, and the grinding wheel 6 will continue to descend to grind the teeth.
