[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Combination Figures 1-3 A device capable of automatically grinding vehicle weld seams includes a base plate 1, with first upright plates 2 symmetrically fixedly connected to both sides of the bottom end of the base plate 1. A rotating shaft 3 rotatably passes through the two sets of first upright plates 2. Rollers 4 are fixedly connected to both ends of the two rotating shafts 3. Second upright plates 5 are symmetrically fixedly connected to the middle of the bottom end of the base plate 1. A drive shaft 6 is rotatably connected between the two second upright plates 5. A grinding roller 7 is fixedly connected to the outer wall of the drive shaft 6. A motor 8 is fixedly connected to one end of one second upright plate 5. The drive end of the motor 8 is fixedly connected to the drive shaft 6. A rotating shaft 3 and the drive shaft 6 are connected by a reduction mechanism 9.
[0023] Specifically, the first vertical plate 2 limits the rotation of the rotating shaft 3 to ensure stable rotation, and the roller 4 moves on both sides of the weld seam. Therefore, the grinding roller 7 can grind the weld seam. Since it moves during grinding, it can achieve automatic grinding and improve grinding efficiency. The speed reduction mechanism 9 can reduce the speed of the rotating shaft 3, so that the speed of the drive shaft 6 and the rotating shaft 3 are different, forming a speed difference, so as to avoid grinding and movement being delayed at the same time.
[0024] Example 2
[0025] See Figure 1 and Figure 4 Furthermore, based on Embodiment 1, a guide plate 10 is fixedly connected to the top of the base plate 1. An arc-shaped guide rod 11 passes through the inner wall of the guide plate 10. Clamping mechanisms for clamping on the vehicle body are provided on both sides of the bottom end of the arc-shaped guide rod 11. The clamping mechanism includes uprights 12 fixedly connected to both sides of the bottom end of the arc-shaped guide rod 11. Two fixing blocks 13 are fixedly connected to one end of each uprights 12 that are close to each other. Clamping plates 14 are slidably connected to the inner side of the fixing blocks 13 corresponding to the one end of each uprights 12 that are close to each other. Two sets of clamping plates 14 are threadedly connected to each other with bidirectional threaded rods 15. The two bidirectional threaded rods 15 and the two sets of fixing blocks 13 are rotatably connected respectively. The bottom of the grinding roller 7 and the bottom of the roller 4 are on the same horizontal plane. The grinding roller 7 and the roller 4 rotate together.
[0026] Specifically, the guide plate 10 and the arc-shaped guide rod 11 can be used for limiting operation during movement, allowing it to move along the arc of the top of the vehicle body, which is convenient for grinding. By rotating the knob, the bidirectional threaded rod 15 can be rotated, and the thread effect of the bidirectional threaded rod 15 can move the clamping plate 14 inward, thereby completing the clamping and fixing operation and preventing the arc-shaped guide rod 11 from shaking and becoming unstable during movement.
[0027] In actual operation, the entire grinding device can first be placed on both sides of the vehicle body weld. Then, rotate the knob and rotate the double-threaded rod 15. The thread effect of the double-threaded rod 15 can move the clamping plate 14 inward and clamp the entire device on the vehicle body, preventing the grinding device from shaking when walking, improving stability, and thus improving the grinding effect.
[0028] Then, the motor 8 is started to rotate the drive shaft 6, which in turn rotates the grinding roller 7 to grind the weld. At the same time, the speed of one of the rotating shafts 3 can be reduced by the deceleration mechanism 9, and the roller 4 can be rotated, so that the grinding device can move along both sides of the weld. Therefore, automatic grinding can be achieved and grinding efficiency can be improved.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
