DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 1-Figure 5 As shown, the utility model provides a metal pipe end grinding device, including a round rod 1. When used, the round rod 1 can be connected to a handheld driving device (not shown in the figure) for rotation, such as: a handheld driving structure of an electric drill. The round rod 1 is similar to a drill bit. The handheld driving structure is an existing common technology and will not be described in detail here.
[0021] The end of the round rod 1 is fixedly connected with a cone head 2, and the cone head 2 can fit on the inner edge of the end of the metal pipe fitting. A protrusion 5 is fixedly connected to the outer wall of the round rod 1, and a rotating plate 3 is rotatably connected to the protrusion 5. A slot 20 for the rotating plate 3 to pass through is provided on the cone head 2, and the rotating plate 3 fits on the inner wall of the slot 20 and slides. A grinding strip 6 is fixedly connected to the side of the rotating plate 3 facing the axis of the cone head 2. The grinding strip 6 can fit on the outer edge of the end of the metal pipe fitting, and when the round rod 1 drives the cone head 2 to rotate, the rotating plate 3 and the grinding strip 6 rotate synchronously, and the inner and outer edges of the end can be polished at the same time; because the rotating plate 3 is rotatably connected to the protrusion 5, its inclination angle can be adjusted, so that the grinding device is suitable for metal pipe fittings of various sizes.
[0022] At the same time, a slot 20 is provided on the cone head 2 for the rotating plate 3 to pass through, which can improve the stability of the synchronous rotation of the cone head 2 and the rotating plate 3.
[0023] In addition, the structure of the rotating plate 3 can be adjusted according to the specific usage, and can be arc-shaped, elongated, etc.
[0024] In order to adjust the inclination angle of the rotating plate 3, a groove 4 is opened on the outer wall of the round rod 1. The groove 4 is located on the side of the protrusion 5 facing away from the cone head 2. A control strip 7 is arranged inside the groove 4. The control strip 7 is fixedly connected to the rotating plate 3. The control strip 7 is arranged at an angle, and the end away from the rotating plate 3 is inclined downward.
[0025] The control strip 7 is provided with a sliding channel 8, and the sliding channel 8 has the same inclination angle as the control strip 7. The round rod 1 is provided with an adjustment component that cooperates with the sliding channel 8, and the adjustment component includes a sliding column 9, a first support block 10 and a slip ring 11. The slip ring 11 is slidably connected to the round rod 1, and the first support block 10 is fixedly connected to the inner wall of the slip ring 11. The sliding column 9 is slidably connected to the sliding channel 8, and the sliding column 9 is fixedly connected to the first support block 10. When the slip ring 11 slides on the round rod 1 toward the cone head 2, the sliding column 9 is driven to move synchronously through the first support block 10. Since the control strip 7 and the sliding channel 8 are arranged in an inclined manner, the end of the rotating plate 3 away from the protrusion 5 is tilted, and the angle between the rotating plate 3 and the outer wall of the cone head 2 becomes larger, which is suitable for metal pipes with thicker walls; and when the slip ring 11 slides on the round rod 1 in the direction away from the cone head 2, the angle between the rotating plate 3 and the outer wall of the cone head 2 becomes smaller, which is suitable for metal pipes with thinner walls.
[0026] In order to control the movement of the slip ring 11, the adjustment assembly further includes a T-shaped ring groove 12, a T-shaped ring block 13 and a threaded ring 14. The threaded ring 14 is threadedly connected to the round rod 1. The T-shaped ring groove 12 is provided on the side of the threaded ring 14 facing the slip ring 11. The T-shaped ring block 13 is rotatably connected to the inside of the T-shaped ring groove 12. The T-shaped ring block 13 is fixedly connected to the slip ring 11. Since the threaded ring 14 is threadedly connected to the round rod 1, when the threaded ring 14 is rotated, and with the cooperation of the T-shaped ring groove 12 and the T-shaped ring block 13, the threaded ring 14 and the slip ring 11 will slide on the round rod 1 synchronously.
[0027] In order to prevent the threaded ring 14 from rotating randomly after adjustment, a limiting groove 15 is provided on the side of the threaded ring 14 facing away from the slip ring 11 . There are multiple limiting grooves 15 , which are evenly distributed around the round rod 1 .
[0028] The round rod 1 is provided with a limiting assembly that cooperates with the limiting groove 15, and the limiting assembly includes a second support block 16, a limiting rod 17, a circular plate 18 and a spring 19. The second support block 16 is fixedly connected to the round rod 1, the limiting rod 17 is slidably connected to the second support block 16, and the limiting rod 17 cooperates with the limiting groove 15. The circular plate 18 is fixedly connected to one end of the limiting rod 17 away from the limiting groove 15, and the spring 19 is sleeved on the outside of the limiting rod 17, one end of the spring 19 is fixedly connected to the circular plate 18, and the other end of the spring 19 is fixedly connected to the second support block 16.
[0029] During operation, the circular plate 18 is pulled away from the threaded ring 14, and the limiting rod 17 is drawn out from the inside of the limiting groove 15, so that the threaded ring 14 can be rotated to adjust the inclination angle of the rotating plate 3; after the adjustment is completed, the circular plate 18 is released, and the restoring elastic force of the spring 19 causes the limiting rod 17 to be inserted into the corresponding limiting groove 15, thereby completing the positioning of the threaded ring 14 and preventing it from rotating, thereby improving the stability of the grinding of the end of the metal pipe fitting.
