[0024] 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.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4 This utility model provides a burr removal device for mechanical parts, including a fixed base 1; a fixed column 2 is fixedly connected to the inner side of both the bottom and top of the fixed base 1; a grinding arm 3 is rotatably connected to the outer side of the fixed column 2; a mounting base 4 is fixedly connected to the end of the grinding arm 3 away from the fixed base 1; grinding abrasive discs 5 are detachably connected to the opposite ends of the two mounting bases 4; an adjusting column 6 is rotatably connected to the center position inside the fixed base 1; an adjusting bolt 7 is fixedly connected to the end of the adjusting column 6 near the mounting base 4.

[0027] The opening assembly is located on the ring side of the adjusting bolt 7. The opening assembly is used in conjunction with the mounting base 4 and the grinding disc 5. During operation, when it is necessary to grind burrs on the inner diameter of pipe fittings, the mounting base 4 and the grinding disc 5 are inserted into the inner diameter of the pipe. Rotating the device causes the mounting base 4 and the grinding disc 5 to grind the burrs on the inner diameter of the pipe. When dealing with pipe fittings of different inner diameters, the opening assembly adjusts the two mounting bases 4 to rotate around the fixed column 2, thereby adjusting the two mounting bases 4 and the grinding disc 5 to a suitable opening angle, facilitating adjustment of the grinding range. This improves the applicability of the device while making it convenient for use with pipe fittings.

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, the opening assembly includes a threaded sleeve 8, a first adjusting seat 9, and a support arm 10. The end of the adjusting bolt 7 away from the fixed seat 1 is threadedly connected to the threaded sleeve 8. The top and bottom ends of the threaded sleeve 8 are both fixedly connected to the first adjusting seat 9. The support arm 10 is rotatably connected to the inner side of the first adjusting seat 9. During operation, the rotation of the adjusting bolt 7 drives the support arm 10 to move on the adjusting bolt 7 via the threaded sleeve 8, facilitating the adjustment of the two grinding arms 3 via the support arm 10.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, the opening assembly also includes a connecting column 11, a fixed sleeve 12, and a second adjusting seat 13; the connecting column 11 is fixedly connected to the inner side of the mounting base 4; the fixed sleeve 12 is fixedly connected to the center of the connecting column 11; the second adjusting seat 13 is fixedly connected to the end of the fixed sleeve 12 near the fixed base 1; the end of the support arm 10 away from the first adjusting seat 9 is rotatably connected to the second adjusting seat 13. During operation, the second adjusting seat 13 limits the support arm 10 and the threaded sleeve 8, facilitating the movement of the threaded sleeve 8 via the adjusting bolt 7. When the threaded sleeve 8 moves towards the fixed base 1, it drives the threaded sleeve 8 to lift the grinding arm 3 around the rotating shaft inside the first adjusting seat 9, thereby driving the grinding arm 3 to rotate and open around the fixed column 2, thus facilitating the adjustment of the distance between the two grinding arms 3 and making it convenient for use with fittings of different pipe inner diameters.

[0030] Furthermore, such as Figure 2 and Figure 3As shown, the opening assembly further includes a first adjusting gear 14, a second adjusting gear 15, a transmission column 16, and a cross-shaped adjusting groove 17. The first adjusting gear 14 is fixedly connected to the end of the adjusting column 6 away from the adjusting bolt 7. The transmission column 16 is rotatably connected inside the fixed base 1 at a position corresponding to the adjusting column 6. The second adjusting gear 15 is fixedly connected to the end of the transmission column 16 away from the adjusting bolt 7. The second adjusting gear 15 meshes with the first adjusting gear 14. The cross-shaped adjusting groove 17 is provided at the end of the transmission column 16 near the adjusting bolt 7. During operation, an external rotating adjusting tool is connected to the transmission column 16 through the cross-shaped adjusting groove 17, thereby rotating the transmission column 16. This causes the transmission column 16 to drive the first adjusting gear 14 and the adjusting column 6 to rotate via the second adjusting gear 15. Consequently, the adjusting column 6 drives the adjusting bolt 7 to rotate, allowing the adjusting bolt 7 to easily drive the support arm 10 to adjust the grinding arm 3.

[0031] Furthermore, such as Figure 4 As shown, the end of the fixed base 1 furthest from the mounting base 4 is threadedly connected to an extension column 18; the end of the extension column 18 furthest from the fixed base 1 is threadedly connected to a mounting column 20. During operation, the structural design of the mounting column 20 and the extension column 18 allows for the extension of the device's operating length when the inner diameter of the pipe fitting is deep. This facilitates the use of the device for pipes with varying inner diameters, further improving its adaptability and effectiveness.

[0032] Furthermore, such as Figure 1 As shown, a rotating base 21 is provided at the end of the mounting column 20 away from the extended column 18; handles 22 are fixedly connected to both sides of the rotating base 21. During operation, the mounting column 20 inside is driven to rotate by the rotating base 21, and then the mounting column 20 drives the grinding arm 3 and the mounting base 4 to grind the burrs on the inner diameter of the pipe through the fixed seat 1.

[0033] Furthermore, such as Figure 4 As shown, an anti-slip pad 23 is fixedly connected to the outer side of the handle 22. During operation, the anti-slip pad 23 enhances the anti-slip function of the handle 22, reducing the risk of slipping out of the hand during use and improving the safety of the device.

[0034] Working principle: When it is necessary to grind burrs on the inner diameter of pipe fittings, the mounting base 4 and the grinding disc 5 are inserted into the inner diameter of the pipe. Rotating the device then drives the mounting base 4 and the grinding disc 5 to grind the burrs on the inner diameter of the pipe. When dealing with pipe fittings of different inner diameters, the two mounting bases 4 are adjusted by opening the assembly and rotating around the fixed column 2. This allows for adjustment of the opening angle of the two mounting bases 4 and the grinding disc 5, facilitating the adjustment of the grinding range and making the device suitable for use with pipe fittings. Simultaneously, to improve the applicability of the device, the rotation of the adjusting bolt 7 drives the support arm 10 to move on the adjusting bolt 7 via the threaded sleeve 8, facilitating the adjustment of the two grinding arms 3 via the support arm 10. The second adjusting seat 13 limits the support arm 10 and the threaded sleeve 8, facilitating the movement of the threaded sleeve 8 via the adjusting bolt 7. When the threaded sleeve 8 moves towards the fixed seat 1, it drives the threaded sleeve 8 to lift the grinding arm 3 around the rotating shaft inside the first adjusting seat 9, thereby driving the grinding arm 3 to rotate around the fixed column 2. The opening allows for easy adjustment of the distance between the two grinding arms 3, facilitating the use of fittings with different inner diameters of pipes. The external rotation adjustment tool is connected to the transmission column 16 via the cross adjustment groove 17. Rotating the transmission column 16 causes it to drive the first adjustment gear 14 and the adjustment column 6 through the second adjustment gear 15. This, in turn, causes the adjustment bolt 7 to rotate, allowing the support arm 10 to easily adjust the grinding arm 3. Through the structural design of the mounting column 20 and the extension column 18, the distance between the two grinding arms 3 can be adjusted when the inner diameter of the pipe fitting changes. When the depth is deep, the operating length of the device can be extended by using the mounting column 20 and the extension column 18, which facilitates the use of the device on pipes with different inner diameters and lengths, further improving the adaptability and effectiveness of the device. By rotating the base 21, the mounting column 20 inside is driven to rotate, and then the mounting column 20 drives the grinding arm 3 and the mounting seat 4 to grind the burrs on the inner diameter of the pipe through the fixed seat 1. The anti-slip pad 23 increases the anti-slip function of the handle 22 of the device, reducing the risk of slipping out of the hand during use and improving the safety of the device during use.

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.
