[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] Sliding bearings made of graphite materials are divided into radial bearings and thrust bearings. Carbon-graphite sliding bearings are used in high and low temperature, high and low speed sliding conditions, and have corrosion resistance to highly corrosive gas and liquid media. At present, when existing graphite bearings need to be polished, it is difficult to stably and quickly position the center of the inner diameter of the graphite bearing.

[0021] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a graphite bearing inner diameter positioning device, comprising a carrier plate 1, a limiting groove 2 is clamped in the middle of the carrier plate 1, the limiting groove 2 is in a cross shape, two limiting blocks 7 are fixed on the carrier plate 1, and one side of the two limiting blocks 7 is provided with a base 3 that slides on the inner wall of the limiting groove 2;

[0022] An inner diameter clamping arm for clamping the inner diameter of the graphite bearing is arranged on the top of the base 3 .

[0023] To ensure the smooth implementation of this embodiment, it should be understood that the inner diameter clamping arm includes a column 4, one side of the column 4 is rotatably connected to a roller 5, and the other side of the column 4 is provided with a rubber strip.

[0024] To ensure the smooth implementation of this embodiment, it should be understood that two ends of the top of the base 3 are provided with slide grooves, and the bottom end of the column 4 is provided with a protrusion slidably connected to the inner wall of the slide groove at the top of the base 3;

[0025] A fixing knob 6 for fixing the column 4 is provided on the top of the column 4 .

[0026] To ensure the smooth implementation of this embodiment, it is necessary to understand that both ends of the limit block 7 are fixed to the top of the carrier 1 by fixing screws, a screw rod 8 is screwed to the middle of the limit block 7, the other end of the screw rod 8 is rotatably connected to one side of the base 3, and a handle is fixed to the other end of the screw rod 8.

[0027] To ensure the smooth implementation of this embodiment, it should be understood that the two limit grooves 2 are cross-set with each other, and a slide groove is provided at both ends of the bottom of each base 3. A slider slides on the inner wall of the slide groove, and the slider is slidably connected to the inner wall of the limit groove 2.

[0028] In order to ensure the smooth implementation of this embodiment, it should be understood that the column 4 is rotatably connected to the top of the protrusion, wherein the bottom sides of the carrier plate 1 are fixed with feet 9 for supporting the carrier plate 1 .

[0029] The graphite bearing inner diameter positioning device comprises a carrier plate 1, a limiting groove 2 is carefully designed in the middle of the carrier plate 1, and the limiting groove 2 is in a cross shape. Two limiting blocks 7 are fixed on the carrier plate 1, and one side of the two limiting blocks 7 is provided with a base 3 that can slide on the inner wall of the limiting groove 2, and the top of the base 3 is provided with an inner diameter clamping arm for clamping the inner diameter of the graphite bearing.

[0030] To ensure the smooth implementation of this embodiment, we need to understand that the inner diameter clamping arm is composed of a column 4, one side of which is rotatably connected to a roller 5, and the other side of the column 4 is set as a rubber strip. This structural design can effectively clamp the inner wall of the graphite bearing. When the inner wall of the graphite bearing is stably polished, the inner wall of the graphite bearing can be stably clamped by one side of the rubber strip to prevent the inner wall of the graphite bearing from sliding. During the polishing process, because the inner wall of the graphite bearing needs to be adjusted, in order to reduce the troublesome steps of removing and fixing the graphite bearing, the inner wall of the bearing can be clamped by one side of the roller 5, so that the inner wall of the graphite bearing can also be adjusted to a certain extent. This design can better adapt to the inner diameter shape of the graphite bearing and ensure precise positioning.

[0031] To further ensure the smooth implementation of the embodiment, sliding grooves are provided at both ends of the top of the base 3, and a protrusion is provided at the bottom end of the column 4, which can be slidably connected to the inner wall of the sliding groove at the top of the base 3. This sliding connection design allows the column 4 to move freely on the base 3 while maintaining stability.

[0032] A fixing knob 6 for fixing the column 4 is also provided on the top of the column 4. The design of the fixing knob 6 is very practical. It can facilitate us to fix the column 4, so as to better maintain the positioning of the inner diameter of the graphite bearing.

[0033] In addition, to ensure the smooth implementation of the embodiment, both ends of the limit block 7 are fixed to the top of the carrier plate 1 by fixing screws, and a screw rod 8 is screwed to the middle of the limit block 7, and the other end of the screw rod 8 is rotatably connected to one side of the base 3, and a handle is fixed to the other end of the screw rod 8. This design allows us to adjust the position of the limit block 7 by turning the handle, thereby better controlling the inner diameter positioning of the graphite bearing.

[0034] The two limit grooves 2 are designed to cross each other, and each base 3 is also provided with a slide groove at both ends of the bottom. A slider slides on the inner wall of the slide groove, and the slider is slidably connected to the inner wall of the limit groove 2. This cross design makes the entire device more stable and precise.

[0035] Finally, the column 4 is rotatably connected to the top of the protrusion, and feet 9 for supporting the carrier 1 are fixed on both sides of the bottom of the carrier 1. The design of these feet 9 makes the entire device more stable and can better support the entire graphite bearing inner diameter positioning device.

[0036] In general, the design of the graphite bearing inner diameter positioning device is very sophisticated and practical. Through a series of carefully designed structures, it achieves accurate and stable positioning of the inner diameter of the graphite bearing, and has a good clamping effect.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
