DETAILED DESCRIPTION
[0021] The utility model will now be further described in detail with reference to the accompanying drawings.
[0022] like Figure 1-2 As shown, an automatic pin grinding device comprises a mounting seat 1, on which a sliding mechanism, an active roller 2 and a passive roller 3 are mounted, the sliding mechanism comprises a threaded rod 4, a slider 5 and a slide bar 6, the threaded rod 4 and the slide bar 6 are mounted on the mounting seat 1, the slider 5 is connected to the threaded rod 4 and the slide bar 6, an electric cylinder 8 and a column 9 are mounted on the slider 5, a first support plate 10 is welded to the output end of the electric cylinder 8, a grinding motor 14 and a first laser stopper 12 are mounted on the first support plate 10, a grinding wheel 15 is mounted to the output end of the grinding motor 14, a second support plate 11 is welded to the top end of the column 9, a second laser stopper 13 is mounted on the second support plate 11, proximity switches 16 are mounted on both sides of the mounting seat 1, and the active roller 2, the sliding mechanism, the electric cylinder 8, the grinding motor 14, the first laser stopper 12, the second laser stopper 13 and the proximity switch 16 are all electrically connected to the controller.
[0023] One axial end of the active roller 2 passes through the mounting seat 1 and is connected to a rotating motor 17 . The rotating motor 17 is fixed on the mounting seat 1 . The active roller 2 is electrically connected to the controller via the rotating motor 17 .
[0024] The active roller 2 and the passive roller 3 are at the same height, and both the active roller 2 and the passive roller 3 are anti-slip rollers. The active roller 2, the passive roller 3, and the rotating motor 17 form a rotating platform. The rotating platform is used to carry the pin shaft so that the pin shaft rotates with the rotation of the active roller 2.
[0025] The threaded rod 4 and the sliding rod 6 are installed on the mounting seat 1 below the rotating platform, and the threaded rod 4 and the sliding rod 6 are respectively located on both sides of the rotating platform. The outer wall of the threaded rod 4 is in the shape of an external thread, and the sliding rod 6 is in the shape of a cylinder with a smooth outer wall. The threaded rod 4 is connected to the mounting seat 1, and the sliding rod 6 is welded to the mounting seat 1 at the same height as the threaded rod 4.
[0026] The sliding mechanism further includes a sliding motor 7, which is mounted at one end of the threaded rod 4, and the sliding mechanism is electrically connected to the controller via the sliding motor 7. The sliding motor 7 drives the threaded rod 4 to rotate, and then causes the slider 5 threadedly connected to the threaded rod 4 to slide on the threaded rod 4, thereby driving the grinding motor 14 to slide.
[0027] One end of the slider 5 is threadedly connected to the threaded rod 4 , and the other end of the slider 5 is threadedly connected to the slide rod 6 . The electric cylinder 8 and the column 9 are respectively located at both ends of the slider 5 , and one end of the slider 5 protrudes out of one side of the mounting seat 1 .
[0028] One end of the first support plate 10 is welded to the output end of the electric cylinder 8, and the other end of the first support plate 10 extends to the upper part between the active roller 2 and the passive roller 3. The grinding motor 14 is installed on the first support plate 10 between the active roller 2 and the passive roller 3. The output end of the grinding motor 14 passes through the first support plate 10 and is connected to the grinding wheel 15. The end of the first support plate 10 on which the grinding motor 14 is installed is tilted upward, and the first laser stopper 12 is installed at the tilted end of the first support plate 10. The first laser stopper 12 is used to limit the lifting and lowering of the electric cylinder 8 so that the grinding wheel 15 can always contact the surface of the pin shaft.
[0029] One end of the second support plate 11 is welded to the top of the column 9, and the other end of the second support plate 11 is tilted downward, and the second laser stopper 13 is installed at the tilted end of the second support plate 11. The second laser stopper 13 is used to limit the grinding thickness, and when the pin is ground to the set thickness, the grinding stops automatically.
[0030] The proximity switch 16 is mounted on the mounting seat 1 on both sides of the end of the slider 5 protruding from the mounting seat 1, so that the slider 5 can slide and touch the proximity switch 16. The proximity switch 16 is limited by the sliding range of the slider 5. When the proximity switch 16 is touched, the sliding motor 7 drives the slider 5 to slide in the opposite direction.
[0031] The working principle of the utility model is:
[0032] During use, the grinding thickness of the pin shaft and the speed parameters of the rotating motor 17, the grinding motor 14, and the sliding motor 7 are set through the controller, and the pin shaft is placed between the active roller 2 and the passive roller 3. After starting, the rotating motor 17 drives the active roller 2 to rotate. Since the active roller 2 and the passive roller 3 are both anti-slip rods, the pin shaft rotates accordingly. At this time, the electric cylinder 8 moves downward. When the first laser stopper 12 determines that the grinding wheel 15 contacts the surface of the pin shaft, the grinding motor 14 drives the grinding wheel 15 to rotate to grind the surface of the pin shaft. During the grinding process, the first laser stopper 12 detects the distance between the first laser stopper 12 and the pin shaft in real time, and adjusts the extension and contraction of the electric cylinder 8 at any time to make the grinding wheel 15 always contact the pin shaft. The proximity switches 16 on both sides of the slider 5 control the action of the sliding motor 7. When the slider 5 touches the proximity switch 16, the sliding motor 7 reverses to make the slider 5 slide in the opposite direction, so that the grinding wheel 15 grinds the surface of the pin shaft in the horizontal direction. After the second laser stopper 13 detects that the grinding thickness of the pin shaft reaches the set value, the controller stops the grinding work. The grinding wheel 15 can be replaced with a grinding wheel 15 or a polishing wheel with higher grinding accuracy to further process the pin.
