[0002] A part refers to an indivisible individual component in machinery. It is a basic element of a machine and a fundamental unit in the mechanical manufacturing process. Its manufacturing process generally does not require assembly steps. Examples include bushings, bearings, nuts, crankshafts, blades, gears, cams, connecting rods, and connecting rod ends.

[0003] In the machinery manufacturing industry, some precision instruments and equipment use circular parts that need to be used in conjunction with other parts. These parts require high-quality internal machining and necessitate grinding. The main functions of internal grinding include removing burrs, debris, particles, roughness, and unevenness; enhancing layer adhesion; and improving dimensional accuracy and surface quality.

[0004] In existing technologies, traditional methods for grinding internal walls are mostly manual, which is not only inefficient but also makes it difficult to guarantee consistent quality for each process. With the improvement of industrial automation, various devices based on robotic arms or industrial robots for grinding internal walls have emerged on the market. Although these devices can achieve partial automation, there is still room for improvement in positioning accuracy, flexibility, and the ability to adapt to internal walls of different shapes. Utility Model Content

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figs. 1 to 3 As shown, this utility model provides a precision grinding and positioning device for the inner wall of mechanical parts, including a grinding table 1. The top of the grinding table 1 is provided with a fixing groove 3. The inner surface of the fixing groove 3 is provided with a plurality of clamping grooves 11. The inner wall of the clamping groove 11 is slidably connected to a clamping plate 13. The side of the clamping plate 13 is connected to the inner surface of the clamping groove 11 through a clamping cylinder 12. A grinding plate 19 is provided above the clamping groove 11. The top of the grinding plate 19 is provided with a mounting hole 18. The inner surface of the mounting hole 18 is threadedly connected to the outer surface of a mounting shaft 17. The top of the mounting shaft 17 is connected to the drive end of a grinding motor 16. The top of the grinding motor 16 is connected to the bottom of a lifting plate 15. The top of the lifting plate 15 is connected to the telescopic end of a lifting cylinder 4. The top of the lifting cylinder 4 is connected to the bottom end of the horizontal part of an L-shaped support plate 5. The bottom of the vertical part of the support plate 5 is connected to the top of the grinding table 1.

[0022] There are multiple grinding plates 19, and the outer diameter of different grinding plates 19 is different, but the size of the mounting holes 18 on them is the same.

[0023] By setting multiple grinding plates 19 of different sizes, the appropriate grinding plate 19 can be selected according to the inner diameter of the cylindrical part to be ground. The grinding plate 19 is installed by connecting the threaded connection with the mounting shaft 17 through the connecting hole. Driven by the grinding motor 16, the grinding plate 19 is rotated to grind the inner wall of the cylindrical part. Driven by the lifting cylinder 4, the grinding motor 16 can be moved, thereby realizing the up and down movement of the grinding plate 19. By using grinding plates 19 of different sizes, they can be used with the inner wall of the parts to be ground, thereby improving the grinding accuracy and applicability.

[0024] Before grinding, the part to be ground is placed in the fixed groove 3. Driven by the clamping cylinder 12, the clamping plate 13 is moved to contact the outer surface of the part, which can fix parts of different sizes and improve the applicability of the clamping plate 13.

[0025] The side of the clamping plate 13 away from the clamping cylinder 12 has an arc-shaped structure.

[0026] By setting an arc-shaped clamping plate 13, the side of the clamping plate 13 can better contact the outer surface of the cylindrical part, thereby improving the stability of the clamping plate 13 in clamping the cylindrical part.

[0027] The clamping plate 13 has a clamping pad 14 bonded to its side, and the clamping pad 14 is made of rubber.

[0028] By setting a rubber clamping pad 14, the pressure on the clamping point of the part can be reduced when the clamping plate 13 clamps the part, preventing the part from being damaged due to excessive force and affecting subsequent use.

[0029] The fixing groove 3 has a cleaning hole 10 on its side. The bottom of the cleaning hole 10 is inclined, and the height of the bottom of the cleaning hole 10 facing the fixing groove 3 is higher than the height of the other end of the bottom of the cleaning hole 10.

[0030] By setting the cleaning hole 10, the debris that falls into the fixing groove 3 can be cleaned during the grinding process and flow out through the cleaning hole 10, which improves the convenience of cleaning debris in the fixing groove 3 and prevents debris from accumulating in the fixing groove 3 and affecting the subsequent fixing of the cylindrical part 2.

[0031] The fixed groove 3 is provided with a limiting plate 6 above it. Both ends of the top of the limiting plate 6 are connected to the telescopic ends of the limiting cylinder 8. The fixed end of the limiting cylinder 8 is connected to the top of the grinding table 1 through the limiting support plate 9. The top of the limiting plate 6 is provided with a through hole 7. The lifting cylinder 4 and the grinding motor 16 are located inside the through hole 7.

[0032] By setting a vertically movable limiting plate 6, during grinding, the limiting plate 6 can be moved downward to contact the top of the cylindrical part 2, applying a downward force to the cylindrical part 2 and improving the stability of the cylindrical part 2 placed in the fixing groove 3.

[0033] Working principle and usage process of this utility model:

[0034] By setting multiple grinding plates 19 of different sizes, the appropriate grinding plate 19 can be selected according to the inner diameter of the cylindrical part to be ground. The grinding plate 19 is installed by connecting the threaded connection with the mounting shaft 17 through the connecting hole. Driven by the grinding motor 16, the grinding plate 19 is rotated to grind the inner wall of the cylindrical part. Driven by the lifting cylinder 4, the grinding motor 16 can be moved, thereby realizing the up and down movement of the grinding plate 19. By using grinding plates 19 of different sizes, they can be used with the inner wall of the parts to be ground, thereby improving the grinding accuracy and applicability.
