Further, it will be appreciated that the dimensions of the various elements shown in the figures are not drawn to scale, for ease of description, and that the thickness or width of some layers may be exaggerated relative to other layers, for example.

It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined or illustrated in one figure, it will not need to be further discussed or illustrated in detail in the description of the following figure.

As shown in fig. 1-4, the utility model provides a technical solution: the utility model provides a mill in stainless steel seamless steel pipe is with high accuracy, including interior mill rotor 1, interior mill rotor 1 is including rotating the platform, rotate platform one side fixedly connected with corase grind elevating system, it grinds elevating system to rotate platform opposite side fixedly connected with fine grinding elevating system, simultaneously corase grind elevating system top fixedly connected with corase grind rotatory piece 101, and the rotary block 110 of fine grinding elevating system top fixedly connected with fine grinding, in this embodiment, it needs to be inserted inside the stainless steel seamless pipe of treating the mill to rotate the platform, in order to can the various stainless steel seamless pipes of comparatively extensive adaptation, consequently it should not be too big to rotate platform size itself. When the rough grinding lifting mechanism and the fine grinding lifting mechanism are completely retracted, the bottom sides of the rough grinding rotating block 101 and the fine grinding rotating block 110 are just in contact with the side wall of the rotating table, the two rotating blocks can be in close contact, and the rough grinding rotating block 101 is slightly higher than the fine grinding rotating block 110. At this time, the distance from the center of the inner grinding rotor 1 to the top end of the rough grinding rotating block 101 is the minimum inner diameter of the stainless steel seamless pipe that can be ground by the inner grinding rotor 1. Because the rough grinding rotary block 101 is higher, the inner grinding rotor 1 will perform rough grinding on the inner wall of the stainless steel seamless tube. When can both be great with the stainless steel seamless pipe internal diameter, elevating system just opens, corase grind elevating system includes slide rail 109, slide rail 109 outside swing joint has elevator motor 108, elevator motor 108 one side fixedly connected with limiting plate 107, limiting plate 107 fixedly connected with extrusion sensor 106, and extrusion sensor 106 and elevator motor 108 electric connection, extrusion sensor 106 top fixedly connected with is in the same direction as straight loop bar 105, extrusion sensor 106 top fixedly connected with extrusion spring 104, extrusion spring 104 top fixedly connected with extrusion post 103. The top end of the extrusion column 103 is fixedly connected with a rotating rod 102, and the top end of the rotating rod 102 is fixedly connected with a rough grinding rotating block 101. When the lifting motor 108 extends the slide rail 109 to move outwards, the rough grinding rotating block 101 is driven to ascend, when the rough grinding rotating block 101 contacts the inner wall of the stainless steel seamless pipe, the rough grinding rotating block stops ascending, but the lifting motor 108 still moves, so that pressure is generated on the extrusion spring 104 to contract, the extrusion spring transmits the pressure to the extrusion sensor 106, the extrusion sensor 106 sends an electric signal to control the lifting motor 108 to stop running and lock the position, and at the moment, the rotating table is rotated again to roughly grind the inner wall. If when the requirement to the stainless steel seamless pipe is higher, after the corase grind is accomplished, staff control elevator motor 108 descends for the corase grind rotatory piece 101 is kept away from the inner wall, and starts fine grind elevating system, in this embodiment, fine grind elevating system and corase grind elevating system structure unanimity, and fine grind elevating system top fixedly connected with fine grind rotatory piece 110, can carry out more careful polishing to the internal diameter, consequently fine grind rotatory piece 110 also can outwards extend to with the contact of stainless steel seamless pipe internal diameter, rotate the revolving stage this moment, alright polish in order to going on meticulous.

The inboard fixedly connected with axis of rotation of revolving stage, axis of rotation one end and actuating mechanism 2 fixed connection, actuating mechanism 2 includes telescopic link 204, telescopic link 204 one end and flexible motor 203 output swing joint. In this embodiment, the telescopic link 204 is multistage flexible, consequently can outwards extend the distance far away to can stretch into longer seamless intraduct with interior mill rotor 1 and polish, and telescopic motor 203 one side fixedly connected with swivel becket, telescopic motor 203 one side swing joint has the rotation rail 202 simultaneously. In this embodiment, the rotating rail 202 is composed of two inner and outer rings, an annular groove is left in the middle, and the rotating ring is just inserted into the annular groove, so that the telescopic motor 203 can rotate smoothly. One end of the rotating rail 202 is fixedly connected with a rotating motor 201, and the output end of the rotating motor 201 is movably connected with a telescopic motor 203. Therefore, when the rotating motor 201 rotates, the telescopic motor 203 also rotates along with the rotating motor, and the telescopic rod 204 and the inner grinding rotor 1 rotate together, so that the inner grinding rotor 1 and the inner wall of the seamless pipe generate friction, and the polishing effect is achieved. The bottom end of the rotating motor 201 is fixedly connected with a rotating fixing seat 205, the bottom end of the rotating fixing seat 205 is fixedly connected with a working platform 3, and the working platform 3 comprises a base 308. The top end of the base 308 is fixedly connected with a rotary bearing table, and the top end of the rotary bearing table is movably connected with the telescopic motor 203. Base 308 top fixedly connected with slope curb plate 306, slope curb plate 306 one side swing joint has rolling wheel 305, and in this embodiment, rolling wheel 305 has a considerable quantity, and evenly distributed is on slope curb plate 306, and when having placed seamless pipe on rolling wheel 305, the seamless pipe can be comparatively light seesaw under the exogenic action. The two sides of the base 308 are fixedly connected with a bracket 307, and the top end of the bracket 307 is fixedly connected with a pulling slideway 304. The outer side of the dragging slide rail 304 is movably connected with a dragging motor 302, the bottom end of the dragging motor 302 is fixedly connected with an extruding motor 303, and the output end of the extruding motor 303 is movably connected with an extruding fixed rod 301. When the internal grinding movement is to be carried out, the pulling motor 302 is kept still, the extrusion fixing rod 301 descends to extrude the top end of the seamless pipe, so that the seamless pipe is kept still, and when the internally ground seamless pipe is to be taken down, the pulling motor 302 moves to drive the seamless pipe to move forwards and backwards.

When using this utility model, the staff will fix the seamless pipe on base 308 earlier, will follow in the interior rotor 1 that grinds embolias the seamless pipe, and the internal diameter that interior rotor 1 that grinds can adapt to the seamless pipe after that carries out the corase grind several times, carries out the fine grinding several times after that to reach suitable interior grinding effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
