[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model provides a grinding disc adjustment frame for a grinding machine, including a handle 1. One end of the handle 1 is fixedly provided with an adjustment mechanism 3, and one end of the adjustment mechanism 3 is fixedly provided with an adaptive mechanism 2. A grinding device 4 is fixedly provided inside the adaptive mechanism 2. The adaptive mechanism 2 includes a base frame 20. One side of the base frame 20 is fixedly connected to the adjustment mechanism 3. Limiting rods 22 are rotatably provided on both sides of the base frame 20. One end of the two limiting rods 22 is fixedly provided with a limiting frame 23. Positioning rods 25 are rotatably provided on both sides of the limiting frame 23. One end of the positioning rods 25 is fixedly connected to one side of the grinding device 4. Rotating grooves 21 are opened on both sides of the base frame 20 and the limiting frame 23. The inner side of the rotating groove 21 is rotatably connected to the limiting rods 22 and the positioning rods 25. When using the adaptive mechanism 2, when the grinding device 4 needs to adapt to grinding objects of different shapes or angles, the base frame 20 serves as a basic support, and the limiting rods 22 on both sides can rotate around the rotating grooves 21, thereby driving the limiting frame 23 to adjust its position. The positioning rods 25 on both sides of the limiting frame 23 also rotate within the rotating groove 21. The mounting base 24 at one end of the positioning rod 25 is fixedly connected to the grinding equipment 4, allowing the grinding equipment 4 to adaptively adjust its angle and position as the positioning rod 25 rotates. The positioning plate 26 on the outer side of the positioning rod 25 fits against the inner wall of one side of the limiting frame 23, playing an auxiliary positioning role and ensuring the stability of the grinding equipment 4 during the adjustment process, thereby achieving adaptive adjustment to different grinding requirements.

[0024] Specifically, the adjustment mechanism 3 includes an adjustment rod 35, one end of which is fixedly connected to the handle 1. A knob 34 is rotatably mounted on one end of the adjustment rod 35. A threaded rod 32 is slidably mounted on the inner side of the adjustment rod 35. One end of the threaded rod 32 is fixedly connected to one side of the base frame 20. The outer side of the threaded rod 32 is threadedly engaged with the inner side of the knob 34. A sliding block 31 is fixedly mounted on one end of the threaded rod 32, and the sliding block 31 slidably engages with the adjustment rod 35. When using the adjustment mechanism 3, the operator holds the handle 1 and rotates the knob 34. The anti-slip texture 33 on the outer side of the knob 34 increases friction, facilitating operation. When the knob 34 rotates, its threaded engagement with the outer side of the threaded rod 32 causes the threaded rod 32 to slide within the adjustment rod 35. The sliding block 31 at one end of the threaded rod 32 slides within the sliding groove 36 on the outer side of the adjustment rod 35, serving a guiding function. The other end of the threaded rod 32 is fixedly connected to the base frame 20. As the threaded rod 32 slides, the base frame 20 and the grinding equipment 4 fixed in the adaptive mechanism 2 will adjust their positions accordingly, thereby realizing flexible adjustment of the position of the grinding equipment 4.

[0025] Furthermore, the inner side of the rotating groove 21 is coated with a damping coating 27, a design that has significant beneficial effects. The damping coating 27 increases the friction between the limit rod 22 and the positioning rod 25 as they rotate within the rotating groove 21, ensuring their stability after being adjusted to the appropriate position and preventing easy shaking or displacement. This helps improve the overall stability of the adaptive mechanism 2, thereby ensuring the positional and angular accuracy of the grinding equipment 4 during the grinding process, reducing grinding errors caused by mechanism shaking, and improving grinding quality.

[0026] Furthermore, a positioning plate 26 is fixedly provided on the outer side of the positioning rod 25, with one side of the positioning plate 26 fitting against the inner wall of one side of the limiting frame 23. The positioning plate 26 serves as an auxiliary positioning element, enhancing the connection stability between the positioning rod 25 and the limiting frame 23 and preventing the positioning rod 25 from shifting during rotation. This helps ensure the accuracy of the grinding equipment 4 in adaptively adjusting its angle and position, improves the overall reliability of the adaptive mechanism 2, and ensures smooth grinding operations.

[0027] It is worth noting that a mounting base 24 is fixedly provided at one end of the positioning rod 25, and the mounting base 24 is fixedly engaged with one side of the grinding equipment 4. The mounting base 24 provides a stable and reliable mounting foundation for the grinding equipment 4, which makes the connection between the grinding equipment 4 and the positioning rod 25 more secure, reducing the risk of the grinding equipment 4 loosening or falling off due to vibration or external force during the grinding process. This helps to improve the working stability of the grinding equipment 4, extend its service life, and also helps to ensure the accuracy and efficiency of the grinding operation.

[0028] It is worth noting that an anti-slip sleeve 30 is fixedly provided on the outer side of the grip 1. The anti-slip sleeve 30 increases the friction when the operator grips the grip 1, making it less tiring for the operator's hands when using the grinding disc adjustment frame of the grinder for a long time, and effectively preventing the grip 1 from slipping out of the hand. This improves the safety and comfort of operation, allowing the operator to grip the grip 1 more stably, thereby controlling the adjustment mechanism 3 and the adaptive mechanism 2 more accurately, ensuring the smooth progress of the grinding operation.

[0029] It is worth noting that the outer side of the adjusting rod 35 is provided with a sliding groove 36, and the inner side of the sliding groove 36 slides in contact with the sliding block 31. The sliding groove 36 provides a clear sliding track for the sliding block 31, enabling the sliding block 31 to maintain a stable direction and trajectory as it slides with the threaded rod 32. This helps reduce the jamming and offset of the sliding block 31 during the sliding process, improves the adjustment accuracy and stability of the adjusting mechanism 3, and allows the operator to more accurately control the position adjustment of the grinding equipment 4, thereby improving the quality of the grinding operation.

[0030] It is worth emphasizing that the outer side of the knob 34 has multiple annularly distributed anti-slip textures 33. These textures increase the surface roughness of the knob 34, thereby increasing the friction between the operator's fingers and the knob 34. This makes it easier and less strenuous for the operator to rotate the knob 34, and allows for more accurate control of the knob's rotation angle, thus achieving precise control of the sliding distance of the threaded rod 32. This helps improve the ease of operation and adjustment accuracy of the adjustment mechanism 3, ensuring the accuracy of the position adjustment of the grinding equipment 4.

[0031] Among them, the grinding equipment 4 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0032] Working Principle: When using the adaptive mechanism 2, if the grinding equipment 4 needs to adapt to grinding objects of different shapes or angles, the base frame 20 serves as the basic support. The limiting rods 22 on both sides of the base frame 20 can rotate around the rotating groove 21, thereby driving the limiting frame 23 to adjust its position. The positioning rods 25 on both sides of the limiting frame 23 also rotate within the rotating groove 21. The mounting base 24 at one end of the positioning rod 25 is fixedly connected to the grinding equipment 4, allowing the grinding equipment 4 to adaptively adjust its angle and position as the positioning rods 25 rotate. The positioning plate 26 on the outer side of the positioning rod 25 fits against the inner wall of one side of the limiting frame 23, providing auxiliary positioning and ensuring the stability of the grinding equipment 4 during adjustment, thus achieving adaptive adjustment to different grinding needs.

[0033] When using the adjustment mechanism 3, the operator holds the handle 1 and rotates the knob 34. The anti-slip texture 33 on the outer side of the knob 34 increases friction, facilitating operation. When the knob 34 rotates, it engages with the threaded rod 32 on the outer side, causing the threaded rod 32 to slide inside the adjustment rod 35. The sliding block 31 at one end of the threaded rod 32 slides within the sliding groove 36 on the outer side of the adjustment rod 35, serving as a guide. The other end of the threaded rod 32 is fixedly connected to the base frame 20. As the threaded rod 32 slides, the base frame 20 and the grinding device 4 fixed in the adaptive mechanism 2 adjust their positions accordingly, thereby achieving flexible adjustment of the position of the grinding device 4.
