[0019] The present invention provides a new energy vehicle frame inner hole grinding machine, which has the following beneficial effects:

[0020] 1. The inner hole grinding machine of the new energy vehicle frame uses the extension of the hydraulic rod to push the flat plate downward, so that the round rod is driven to move downward, and then the height of the grinding point and the strip groove is adjusted. At the same time, the output end of the servo motor is used to drive the round rod to rotate through the coupling. At this time, the grinding point will rotate with the round rod. At this time, the rotating grinding point can grind the inner hole of the new energy vehicle frame, and under the guidance of the strip groove, the debris and dust generated by the grinding will fall along the strip groove, so that the debris can be handled in time to reduce the impact of the debris.

[0021] 2. When the round rod rotates, the inner hole grinder of the new energy vehicle frame can not only drive the grinding point to rotate, so that the inner hole of the new energy vehicle frame is polished, but also drive the fan blades to rotate together, and use the fan blades to be inclined. At this time, the rotating fan blades blow the air, and the blown air forms an airflow that blows downward from the through hole, thereby blowing the dust and chips generated by grinding downward to reduce dust diffusion.

[0022] 3. The inner hole grinding machine of the new energy vehicle frame extends the cylinder. At this time, the output end of the cylinder pushes the cover to move. At this time, the symmetrical covers on both sides move toward each other. At this time, the two covers are merged together, and the grinding points can be covered during grinding, thereby reducing the splashing of debris and sundries, making grinding safer and having good safety performance.

[0023] Fourth, the inner hole grinding machine of the new energy vehicle frame utilizes the movement of the cover shell to drive the pressing teeth to move. At this time, the pressing block is at the top of the new energy vehicle frame, and under the elastic force of the curved elastic strip, the pressing block applies pressing force to the new energy vehicle frame. At this time, the new energy vehicle frame is not easy to deviate at will, so that the grinding is accurate.

[0024] 5. When the symmetrical covers on both sides move toward each other, the inner hole grinding machine of the new energy vehicle frame uses the balls to fit the surface of the round rod, and the sliding push rod is subjected to a reverse force, so that the sliding push rod slides outward, and the elastic part is stretched, and the round rod is supported by the combined action force and reaction force, and the rolling of the balls makes the round rod less likely to shake during rotation, making the rotation more stable.

[0025] 6. The inner hole grinder of the new energy vehicle frame falls with the guidance of the strip groove, and the airflow blows the grinding dust into the dust collecting tube under the blowing of the fanning blades during rotation, and under the guidance of the conical funnel, the dust filter net filters the debris in time, and uses the tip of the anti-backflow cone to face upward, so that the bottom diameter of the anti-backflow cone is larger, thereby reducing the backflow of grinding debris due to the influence of the airflow.

[0048] One end of the elastic member 652 away from the outer surface end of the sliding push rod 651 is fixedly connected to the outer surface of the cover shell 63, so that the elastic member 652 can be stretched after the sliding push rod 651 moves outward.

[0051] The axis of the conical funnel 82 coincides with the axis of the backflow prevention cone 84 , the top of the backflow prevention cone 84 extends to the inside of the conical funnel 82 , and the tip of the backflow prevention cone 84 faces upward to facilitate the falling of debris.

[0053] When in use, first put the new energy vehicle frame that needs to be polished on the workbench 4, then use the extension of the hydraulic rod 51 to push the flat plate 52 downward, so that the round rod 54 is driven to move downward, and then the height of the polishing point 56 and the strip groove 55 is adjusted. When the bottom end of the round rod 54 is close to the top of the new energy vehicle frame, the extension of the hydraulic rod 51 is paused, and then the cylinder 62 is turned on. At this time, the cylinder 62 is extended, and the output end of the cylinder 62 pushes the cover 63 to move. At this time The symmetrical covers 63 on both sides move toward each other, and the two covers 63 are merged together. At this time, the servo motor 53 is turned on, and the output end of the servo motor 53 drives the round rod 54 to rotate through the coupling. At this time, the grinding point 56 will rotate with the round rod 54, and the hydraulic rod 51 is turned on again, so that the hydraulic rod 51 continues to extend. At this time, the rotating grinding point 56 can grind the inner hole of the new energy vehicle frame, and under the guidance of the strip groove 55, the debris and dust generated by grinding will fall along the strip groove 55;

[0054] At the same time, the ball 654 is fitted with the surface of the round rod 54, and the sliding push rod 651 is subjected to a reverse force, so that the sliding push rod 651 slides outward, and the elastic member 652 is stretched, and the round rod 54 is supported by the combined force and the reaction force, and the rolling of the ball 654 makes it difficult for the round rod 54 to shake when rotating, and the movement of the cover 63 is used to drive the pressing tooth 64 to move. At this time, the pressing block 67 is at the top of the new energy vehicle frame, and under the elastic force of the curved elastic strip 68, the pressing block 67 applies a pressing force to the new energy vehicle frame. At this time, the new energy vehicle frame is not easy to deviate at will, so that the grinding is accurate;

[0055] Moreover, as the debris falls under the guidance of the strip groove 55, and the blades 57 are blown during rotation, the airflow blows the grinding dust into the dust collecting tube 81, and under the guidance of the conical funnel 82, the dust filter 86 filters the debris in time, and the tip of the anti-backflow cone 84 is pointed upward, so that the bottom diameter of the anti-backflow cone 84 is larger, thereby reducing the grinding debris from being affected by the airflow and flowing back.

[0056] When the inner hole of the new energy vehicle frame is polished, the cylinder 62 contracts. At this time, the output end of the cylinder 62 drives the cover shell 63 to move toward both ends, and the pressing teeth 64 will be driven to move together. At this time, the pressing block 67 is separated from the polished new energy vehicle frame. At this time, the pressing is ended, and the hydraulic rod 51 is contracted so that the output end of the hydraulic rod 51 drives the flat plate 52 to move upward. At this time, the round rod 54 is lifted, and the servo motor 53 is turned off to stop the round rod 54 from rotating. At this time, the screws on the surface of the cover plate 85 are removed, and the cover plate 85 is removed, and the debris collected in the dust collecting tube 81 can be cleared.
