[0021] A process for grinding automobile bolts, using the aforementioned automobile bolt grinding machine, comprises the following steps: S1: Confirm that the operating table and support frame are firmly fixed, the motor and grinding wheel are reliably connected through the bearings, and the grinding wheel rotates smoothly without abnormal noise when the motor is running; the moving bar slides smoothly along the limit rod in the moving groove, and the first damping rod and the first spring expand and contract normally; the rubber ring in the round frame is not damaged and the gap is intact; the threaded rod rotates flexibly, and the sliding bar slides without sticking in the rectangular groove; the sliding block slides smoothly along the round rod in the slide groove, the extrusion bar slides normally along the locking rod, and the second bolt rotates flexibly; S2: Align the head of the automotive bolt with the rubber ring in the circular frame. Utilizing the elastic deformation of the notch at the top of the rubber ring, insert the bolt head into the circular frame, with the bolt shaft facing the grinding wheel. Manually rotate the threaded rod. As the threads on the threaded rod surface reverse from the center to the sides, the two sliding bars in the rectangular groove move toward the center. Under the elastic action of the third damping rod and the third spring, the rubber arc plate on the sliding bar tightly wraps around the bottom of the bolt head, achieving flexible clamping. Push the sliding block to slide along the circular rod, so that the rotating ring drives the extrusion bar to move directly above the bolt head. Rotate the second bolt. Under the limit of the locking rod, the rubber round block at the bottom of the extrusion bar adaptively fits and presses the top of the bolt head through the rotating block, completing the fixation. S3: Loosen the first bolt. Under the action of the first spring, the movable bar moves along the limit rod toward the grinding wheel until the distance between the bolt rod and the grinding wheel meets the requirements. Turn the first bolt to squeeze the rubber strip, and use the rubber deformation to fix the movable bar. At the same time, the second spring pulls the rubber block to squeeze the limit frame and the side of the operating table to assist in fixing. Circumferential angle adjustment: Manually rotate the circular frame so that the rotating disk at the bottom rotates on the top of the movable bar, driving the bolt to rotate to the desired grinding angle. S4: Start the motor, drive the grinding wheel through the bearing transmission, and adjust the speed according to the material of the bolt; fine-tune the tightness of the first bolt, use the elastic buffer of the first spring to slowly move the bolt closer to the grinding wheel, and the first damping rod absorbs the grinding vibration to ensure grinding accuracy; if the force needs to be adjusted, the pressing force of the extrusion strip can be fine-tuned through the second bolt; S5: Turn off the motor, wait until the grinding wheel stops completely, rotate the second bolt and threaded rod in the opposite direction, loosen the extrusion bar and the sliding bar, and remove the bolt; clean the grinding debris in the operating table and the round frame, and check whether there are any impurities remaining in the parts of the limit device to ensure smooth use next time.
[0022] In the present invention, a limiting device is provided. When the limiting device is used, the head of the automobile bolt is set inside the circular frame, and then moved toward the grinding wheel by the first spring, so that the automobile bolt is close to the grinding wheel, which makes it easier for the grinding wheel to grind the automobile bolt.
