[0022] The embodiment of the present application provides an adjustable inner diameter grinder, which solves the problem that, due to the different inner diameters of different workpieces, the grinding head at the output end of the inner diameter grinder often needs to be replaced in order to match different workpieces. By replacing grinding tools with different diameters or shapes, the grinding radius can be directly changed, but this method of adjusting the grinding radius is not convenient and fast enough.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model embodiment discloses an adjustable inner diameter grinding machine, according to the attached Figure 1-4 As shown, it comprises a grinding machine shaft 1, an adjusting seat 2 is fixedly connected to the grinding machine shaft 1, a slider 5 is slidably connected inside the adjusting seat 2, a movable rod 6 is fixedly connected to the slider 5, and the movable rod 6 passes through the adjusting seat 2 and is fixedly connected to a fixing plate 7;

[0025] A grinding sheet 10 is provided on the fixed plate 7, and an elastic component is provided between the fixed plate 7 and the grinding sheet 10;

[0026] The adjusting seat 2 is provided with an adjusting mechanism for driving the slider 5 to shift and adjust. The adjusting mechanism includes a double-threaded screw 3 rotatably connected inside the adjusting seat 2 , a nut seat 4 is threadedly connected to the double-threaded screw 3 , and the nut seat 4 is fixedly connected to the slider 5 .

[0027] Furthermore, the elastic component includes a connecting rod 8 fixedly connected to the fixed plate 7, to which an arc-shaped elastic plate 9 is fixedly connected, and a grinding sheet 10 is fixedly connected to the arc-shaped elastic plate 9. The overall structure of the elastic component is simple, and the connecting rod 8 and the arc-shaped elastic plate 9 are used to provide support and limit for the grinding sheet 10. Therefore, after rotation, the arc-shaped elastic plate 9 is subjected to centrifugal force and expands and deforms outward, thereby pushing the grinding sheet 10 to fit well with the inner wall of the workpiece, exerting pressure, and ensuring a good grinding effect.

[0028] Furthermore, a shaft seat 201 is fixedly connected to the adjustment seat 2, and the double-threaded screw rod 3 is rotatably connected in the shaft seat 201. The shaft seat 201 is provided to provide support and limit for the double-threaded screw rod 3, thereby ensuring that the force on the double-threaded screw rod 3 is stable.

[0029] Furthermore, a rotating handle 301 is fixedly connected to the double-threaded screw 3, and the rotating handle 301 is convenient and labor-saving when the double-threaded screw 3 is rotated. When the double-threaded screw 3 is rotated, the double-threaded screw 3 drives the nut seat 4 and the slider 5 to slide along the inside of the adjustment seat 2, and the slider 5 then drives the movable rod 6 to move, and the movable rod 6 drives the fixed plate 7 to move, and the fixed plate 7 drives the connecting rod 8 to move, and the connecting rod 8 drives the arc elastic plate 9 to move, and the arc elastic plate 9 drives the grinding plate 10 to move, so as to realize the lateral adjustment of the position of the grinding plate 10 and the radius of the grinding plate 10, thereby quickly adjusting the grinding radius of the grinder.

[0030] Furthermore, a slide groove 202 is provided on the adjustment seat 2, and the slider 5 is slidably connected in the slide groove 202. The slide groove 202 is provided to provide support and limit for the slider 5, so that the force applied to the slider 5 is stable.

[0031] It is particularly disclosed that a circular hole corresponding to the movable rod 6 is opened on the adjustment seat 2, and the circular hole enables the adjustment seat 2 to provide support and limit for the movable rod 6.

[0032] The adjustable inner diameter grinder is convenient for adjusting the grinding radius of the grinder. During the adjustment process, the double-threaded screw 3 can be directly rotated to finally adjust the position of the grinding plate 10 to move laterally, so as to directly adjust the grinding radius, which is easy to operate. At the same time, with the design of the elastic component, when the grinding plate 10 rotates to grind the inner diameter of the material, the centrifugal force of the rotation will cause the rotation radius of the grinding plate 10 to expand outward, so that the grinding plate 10 and the inner wall of the material have pressure, so the grinding plate 10 has good fit with the inner wall of the material, which meets the use requirements.
