[0013] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0014] To address the problems existing in the prior art, this embodiment provides the following technical solution: a high-strength stainless steel pipe inner hole finishing device, comprising an operating table 1 and a steel pipe body 2. A limiting mechanism 3 is provided on the outer side of the steel pipe body 2, located at the upper middle part of the operating table 1. The limiting mechanism 3 can firmly limit the steel pipe body 2, ensuring that the position of the steel pipe body 2 will not shift during the inner hole finishing process. Simultaneously, an adjustment mechanism 5 is provided, located on the upper inner side of the operating table 1, which can adjust the position of the grinding component 4 to enable it to finish steel pipe bodies 2 of different lengths. Furthermore, a chip suction mechanism 6 is provided on the left rear side of the steel pipe body 2, which can absorb and treat the waste chips left after the inner hole finishing process.

[0015] like Figure 1 and Figure 3As shown, three sets of first limiting blocks 31 are horizontally arranged at the upper middle part of the operating table 1. The steel pipe body 2 to be finely repaired can be placed inside the first limiting block 31. The steel pipe body 2 is made of high-strength stainless steel (such as 304L, 316L, etc.). A second limiting block 37 is arranged above the first limiting block 31. The size of the second limiting block 37 is the same as that of the first limiting block 31. At the same time, a connecting rod 32 is fixedly connected to the rear side of the second limiting block 37. A movable frame 34 is fixedly connected to the upper middle part of the connecting rod 32. The movable frame 34 is slidably arranged in front of the bracket 33. In addition, a rotating disk 3 is arranged inside the movable frame 34. 5. The first motor 36 is fixedly connected to the rear side of the rotating disk 35. The first motor 36 can be turned on, and the first motor 36 can make the rotating disk 35 rotate. When the rotating disk 35 rotates, it can slide in the middle of the moving frame 34, thereby pushing the moving frame 34 to move up and down. When the moving frame 34 moves downward, the connecting rod 32 and the second limiting block 37 will also move downward. The second limiting block 37 can firmly limit the steel pipe body 2 with the lower first limiting block 31. It can limit the steel pipe body 2 in three parts, which can effectively ensure that the steel pipe body 2 will not shift its position when the inner hole of the steel pipe body 2 is processed later. like Figure 2 and Figure 4 As shown, after the steel pipe body 2 is limited to the middle and above the operating table 1, the grinding components 4 are symmetrically arranged on the left and right sides of the middle of the operating table 1. The grinding wheel 41 is arranged on the left and right sides of the upper middle of the operating table 1. The grinding wheel 41 is installed at the output end of the first push rod 42. At the same time, the second motor 43 is fixedly connected to the outside of the first push rod 42. Secondly, the right side of the second motor 43 is located on the outside of the fixed frame 51, and the right side of the second motor 43 is located on the left end of the support plate 66. The support plate 66 is located on the upper side of the fixed frame 51. The fixed shaft 52 is slidably connected inside the fixed frame 51. The fixed shaft 52 is symmetrically fixed and installed on the upper inner side of the operating table 1. The lower side of the fixed frame 51 is connected to the outer end of the push rod 53, and the inner end of the push rod 53 is rotatably connected to the rotating plate 54. The rotating plate 54 is rotatably located on the upper inner side of the operating table 1. The lower end of the rotating plate 54 is connected to the third motor 55. When the third motor 55 is turned on, the rotating plate 54 will rotate, which will drive the push rod 53 to move. At this time, the outer end of the push rod 53 will push the fixed frame 51 connected to it to move outside the fixed shaft 52, thereby adjusting the position of the fixed frame 51. The grinding assembly 4 is set on the upper side of the fixing frame 51, and the position of the entire grinding assembly 4 can be adjusted. The grinding assembly 4 can be effectively adjusted according to the length of the steel pipe body 2. The position of the grinding wheel 41 can be adjusted to fit the outer left and right sides of the steel pipe body 2. Then, the first push rod 42 is opened. The output end of the first push rod 42 can push the grinding wheel 41 into the inner hole of the steel pipe body 2. At the same time as the grinding wheel 41 is opened, the second motor 43 is also opened. That is, the grinding wheel 41 can be spirally pushed from both sides of the inner hole of the steel pipe body 2 to grind and refine the inner hole of the steel pipe body 2. like Figure 1 , Figure 2 and Figure 5 As shown, after the steel pipe body 2 is finished by grinding, the grinding wheel 41 is moved out of the steel pipe body 2. A chip suction mechanism 6 is set at the left rear end of the grinding wheel 41, with the chip suction port 61 located at the left rear end of the steel pipe body 2. The chip suction port 61 is installed at the output end of the second push rod 62. At the same time, a support plate 66 is installed at the rear end of the second push rod 62. The lower side of the support plate 66 is located inside the electromagnetic slide rail 7. The controller of the electromagnetic slide rail 7 can be turned on, allowing the support plate 66 to slide inside the electromagnetic slide rail 7. The connection and movement between the electromagnetic slide rail 7 and the support plate 66 are achieved by using the magnetic field generated by the electromagnetic coil and the magnetic field inside the support plate 66. Driven by the interaction of materials, the chip suction port 61 can be adjusted to the left side of the steel pipe body 2. Then, by opening the second push rod 62 on the rear side of the chip suction port 61, the output end of the second push rod 62 can push the chip suction port 61 to the right so that it can fit with the left end of the steel pipe body 2. A chip suction pipe 63 is installed on the rear side of the chip suction port 61, and an air suction pump 64 is installed below the chip suction pipe 63. The air suction pump 64 is located on the upper side of the chip collection box 65. The air suction pump 64 can be turned on, and the air suction pump 64 can transmit suction to the chip suction pipe 63, and then the waste chips inside the steel pipe body 2 can be sucked into the chip collection box 65 for unified collection through the chip suction port 61. The motor model mentioned above is Z4-180-21, and the push rod model is HB-DJ801.

[0016] The working principle of this high-strength stainless steel pipe inner hole finishing device is as follows: A limiting mechanism 3 is set at the upper middle part of the operating platform 1, which can firmly fix the steel pipe body 2 at the upper middle part of the operating platform 1. Grinding components 4 are symmetrically arranged on the left and right sides of the upper middle part of the operating platform 1. An adjustment mechanism 5 is set at the lower outer side of the grinding component 4. The adjustment mechanism 5 can flexibly adjust the position of the grinding component 4, so that it can grind and finish the inner hole of steel pipe body 2 of different lengths. Secondly, a chip suction mechanism 6 is set at the rear left side of the steel pipe body 2. The chip suction mechanism 6 can uniformly absorb and treat the waste chips left by grinding and finishing inside the steel pipe body 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
