[0002] Pipe fittings are a general term for components in pipeline systems that serve to connect, control, change direction, divert, seal, and support. Steel pipe fittings are all pressure-bearing pipe fittings. Based on different processing techniques, they are divided into four categories: butt-weld pipe fittings (with and without welds), socket-weld and threaded pipe fittings, and flanged pipe fittings. Usually, during pipe fitting processing, in order to make the surface of the pipe fittings smooth, it is necessary to grind and polish the surface of the pipe fittings.

[0022] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 - Figure 5 As shown, a metal pipe grinding and positioning mechanism includes a placing mechanism, an adjusting mechanism, a weighing mechanism, a fixing rod 2 and a mounting hole 3 arranged on a placing table 1. The bottom end of the fixing rod 2 is fixedly connected to the top end of the placing table 1. The mounting hole 3 is opened at the top end of the fixing rod 2. The placing mechanism is arranged on the outside of the fixing rod 2, the adjusting mechanism is arranged inside the mounting hole 3, the placing mechanism and the adjusting mechanism are in contact with each other, and the weighing structure is arranged above the fixing rod 2.

[0024] Furthermore, the placement mechanism includes symmetrically arranged first sliding holes 4, two first sliding holes 4 are opened on the outer wall of the fixed rod 2, and a sliding ring 5 is slidably connected inside the mounting hole 3. The outer wall of the sliding ring 5 passes through the two first sliding holes 4 and is fixedly connected to two placement plates 6. A connecting hole 20 is opened at the bottom end of the two placement plates 6 to facilitate the two placement plates 6 to support the position of the pipe fitting, and to facilitate the subsequent height adjustment of the two placement plates 6 according to the size of the inner wall of the pipe fitting.

[0025] Furthermore, the adjustment mechanism includes two symmetrically arranged rotating rods 10, the two rotating rods 10 are rotatably connected to the inner wall of the mounting hole 3, the outer wall of one rotating rod 10 is fixedly connected to a first rotating plate 11, and a clearance hole 12 is opened on one side of the first rotating plate 11, and the outer wall of the other rotating rod 10 is fixedly connected to a second rotating plate 13, and the outer walls of the two rotating rods 10 are fixedly connected to connecting gears 14, and the two connecting gears 14 are meshed. The bottom ends of the first rotating plate 11 and the second rotating plate 13 are both provided with a second sliding hole 15, and the second sliding hole Two slide grooves 22 are provided on the inner wall of 15. The two slide grooves 22 are symmetrically arranged. The adjacent slide grooves 22 are slidably connected with the same slide rod 21. The outer walls of the two slide rods 21 are rotatably connected with the movable plate 16. One side of the movable plate 16 passes through the outer wall of the fixed rod 2 and is fixedly connected to the connecting rod 17. One end of the connecting rod 17 is fixedly connected to the connecting plate 18. The top end of the connecting plate 18 passes through the connecting hole 20 and is fixedly connected to the limiting plate 19. Due to the restriction of the fixed rod 2, the connecting rod 17 can only move horizontally left and right, thereby facilitating the adjustment of the position of the limiting plate 19.

[0026] Furthermore, the inner wall of the sliding ring 5 contacts the outer wall of the first rotating plate 11 , thereby limiting the rotation angles of the first rotating plate 11 and the second rotating plate 13 .

[0027] Furthermore, one side surface of the two limiting plates 19 is configured as an arc-shaped surface protruding toward the outer wall of the fixing rod 2, and the bottom surfaces of the two limiting plates 19 are spaced from the top surface of the placement plate 6, so that the two limiting plates 19 can support the inner diameter of the external pipe fitting.

[0028] Furthermore, the weighing mechanism includes two support rods 7, the bottom ends of the two support rods 7 are fixedly connected to the top end of the sliding ring 5, the two support rods 7 are symmetrically arranged, and the same weighing block 8 is arranged above the two support rods 7. A positioning hole 9 is opened at the bottom end of the weighing block 8 near the outer wall of the two support rods 7. When the two positioning holes 9 are respectively sleeved on the two support rods 7, the position of the weighing block 8 is restricted, so that the weighing block 8 suppresses the position of the sliding ring 5, further improving the support of the two limiting plates 19 to the pipe fittings.

[0029] Working principle: First, the pipe fitting is sleeved on the fixed rod 2 so that the bottom end of the pipe fitting contacts the top end of the placement plate 6. At this time, due to the weight of the pipe fitting itself, the pipe fitting drives the placement plate 6 to move downward, thereby driving the placement plate 6 to drive the sliding ring 5 to move downward, and then the sliding ring 5 drives the bottom of the first rotating plate 11 and the second rotating plate 13 to expand toward the outside of the fixed rod 2 under the action of the two rotating rods 10. At this time, the rotation of the bottom of the first rotating plate 11 and the second rotating plate 13 drives the movable plate 16 to rotate on the sliding rod 21, while the sliding rod 21 moves downward inside the sliding groove 22, so that the movable plate 16 drives the connecting rod 17 to move toward the outside of the fixed rod 2, and then the fixed rod 2 drives the fixed plate to move toward the outside of the fixed rod 2 in the connecting hole 20. Drive the limiting plate 19 to move toward the outside of the fixed rod 2. When the two limiting plates 19 contact the inner wall of the pipe, the two limiting plates 19 no longer move due to the size limitation of the inner wall of the pipe, and the inner wall of the sliding ring 5 contacts the outer wall of the first rotating plate 11, limiting the rotation angle of the first rotating plate 11 and limiting the two connecting gears 14 at the same time. In this way, the angles of the first rotating plate 11 and the second rotating plate 13 are both limited. In this way, the two limiting plates 19 support and limit the inner wall of the pipe, and then pull the weighing block 8 so that the two positioning holes 9 at the bottom end of the weighing block 8 are sleeved on the two support rods 7, so as to further improve the support of the two limiting plates 19 to the pipe, so that the staff can ensure the stability of the pipe when grinding with a grinder.
