[0030] See Figure 1 , Figure 2 , Figure 3 This utility model discloses a multi-angle polishing auxiliary tool, comprising a main body 1, an upper mounting component 3 disposed on the upper side of the main body 1, an angle adjustment mechanism 5 disposed between the upper mounting component 3 and the main body 1, and a fixing component 2 disposed on the main body 1 for fixing the part to be polished. The angle adjustment mechanism 5 is used to adjust the tilt angle of the upper mounting component 3 and the fixing component 2 relative to the main body 1. The fixing component 2 is rotatably disposed on the upper mounting component 3. The upper mounting component 3 is provided with a rotation drive component 4 for driving the fixing component 2 to rotate around its axis, and the fixing component 2 has an operating part for manual control of its rotation. This embodiment is mainly used for polishing disc-shaped parts such as watch dials. In use, the part to be polished is fixed on the fixing component 2. See reference. Figure 9 Then, the grinding equipment is placed facing the fixed component 2. The angle adjustment mechanism is used to adjust the tilt angle of the fixed component 2 and the parts set on the fixed component 2. Then, the multi-angle grinding auxiliary tool is moved to make the parts fit the grinding equipment for grinding. During the grinding process, the parts can be rotated by the rotating drive component 4 to uniformly grind them in the circumference. Alternatively, the fixed component 2 can be manually rotated to grind specific positions or angles, meeting various grinding needs. Grinding is more convenient, and there is no need to hold the parts during the grinding process, improving safety. The grinding angle is adjustable to meet various grinding needs.

[0031] For details on the structure of fixed component 2, please refer to... Figure 4 , Figure 6 , Figure 7It includes a fixed body 21 and six elastic blocks 22 arranged in a ring array on the fixed body 21. A gap is provided between adjacent elastic blocks 22. The outer ring wall of each elastic block 22 has a fixing surface for engaging with the part to be polished. The inner ring wall of each elastic block 22 has a first conical surface 221. A control screw 23 is threadedly connected to the fixed body 21. The control screw 23 has a second conical surface 241 that matches the first conical surface 221. When the control screw 23 moves, the engagement of the second conical surface 241 with the first conical surface 221 drives each elastic block 22 to expand outward or retract inward. When each elastic block 22 expands outward, it engages with holes on the part to be polished, thus fixing it in place.

[0032] For details, please refer to Figure 6 , Figure 7 The screw head of the control screw 23 is fitted with a control block 24 that is separately disposed therefrom. The second conical surface 241 is disposed on the control block 24. The center of the control block 24 is provided with a connecting hole that mates with the screw head of the control screw 23. The second conical surface 241 is separately disposed on the control block 24 to facilitate screw rotation and reduce resistance during screw rotation.

[0033] See also Figure 4 , Figure 6 The fixing component 2 also includes a mounting part 25 for connecting with the upper mounting part 3, and the fixing body 21 is detachably disposed on the mounting part 25. Various models of fixing bodies 21 can be provided, allowing for the selection and replacement of a suitable model of fixing body 21 onto the mounting part 25 when grinding parts of different sizes, thereby improving adaptability and meeting various usage requirements.

[0034] For details regarding the specific structure of the angle adjustment mechanism 5, please refer to [link / reference]. Figure 1 , Figure 4 and Figure 5 It includes a first hinge shaft 51, a first gear 52, and a second gear 53. The main body 1 and the upper mounting member 3 are hinged together via the first hinge shaft 51. The first gear 52 is fixedly connected to the first hinge shaft 51 and is fixedly connected to the upper mounting member 3. A second gear 53 is provided next to the first gear 52 and meshes with it. The diameter of the first gear 52 is larger than the diameter of the second gear 53. The second gear 53 is rotatably mounted on the main body 1 via a gear shaft 531. A rotation operating member 54 is mounted on the gear shaft 531 to control the rotation of the second gear 53. By rotating the second gear 53 through the rotation operating member 54, the first gear 52 and the upper mounting member 3 are rotated, thereby adjusting the relative tilt angle of the upper mounting member 3. Since the diameter of the first gear 52 is larger than the diameter of the second gear 53, a finer angle adjustment can be achieved when the second gear 53 is rotated through the rotation operating member 54.

[0035] See Figure 1 , Figure 5 The gear shaft 531 is also provided with a locking nut 55 threadedly connected to its end. The locking nut 55 is used to engage with the main body 1. When the locking nut 55 is tightened, it can generate a locking force on the gear shaft 531 by engaging with one side of the main body 1, thereby preventing the gear shaft 531 from rotating and locking the angle adjustment mechanism 5 to prevent loosening during the grinding process.

[0036] Specifically, in this embodiment, the rotary drive component 4 is an electric motor, and the upper mounting component 3 is provided with a transmission shaft 32 that is rotatably connected to it. The electric motor is connected to the fixed component 2 through the transmission shaft 32. Example 2

[0037] See Figure 1 , Figure 2 , Figure 4 Based on Embodiment 1, the main seat 1 is provided with a connecting shaft 11 and a movable seat 12 movably mounted on the connecting shaft 11. The movable seat 12 can rotate around the connecting shaft 11 and slide back and forth along the axial direction of the connecting shaft 11. The angle adjustment mechanism 5 is mounted on the movable seat 12, and the axial direction of the connecting shaft 11 is perpendicular to the rotation axis of the angle adjustment mechanism 5. In practical use, the movable seat 12 can move along the connecting shaft 11 towards or away from the grinding equipment, and can also rotate around the connecting shaft 11 to adjust the angle, thereby realizing angle adjustment of the fixed component 2 and the workpiece fixed on the fixed component 2 in another direction, further improving adjustability.

[0038] See Figure 1 , Figure 4 and Figure 5 The main body 1 includes a lower magnetic base 13 and an upper magnetic base 14 that magnetically engages with the lower magnetic base 13. The lower magnetic base 13 is mounted on the movable base 12, and the angle adjustment mechanism 5 is mounted on the upper magnetic base 14. In this embodiment, the magnetic engagement between the lower magnetic base 13 and the upper magnetic base 14 allows for a detachable magnetic engagement between the upper magnetic base 14 and the components fixedly mounted above it, making it more convenient to use and maintain. Example 3

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 8The fixing component 2 is provided with a limiting pin 26, and the upper mounting component 3 is provided with a limiting angle adjustment mechanism 31 that cooperates with the limiting pin 26. The limiting angle adjustment mechanism 31 includes a first limiting block 311 and a second limiting block 312. There is a space between the first limiting block 311 and the second limiting block 312 that cooperates with the limiting pin 26. The limiting pin 26 can move within this space. The first limiting block 311 and the second limiting block 312 are both rotatably mounted on the upper mounting component 3 via a first rotating ring 313. The limiting angle adjustment mechanism 31 also includes a ring fixing component 314 for fixing the position of the first rotating ring 313. The ring fixing component 314 is a screw structure. The limiting pin 26, in conjunction with the first limiting block 311 and the second limiting block 312, can limit the rotation angle range of the fixed component 2, satisfying some directional grinding requirements. Since the first limiting block 311 and the second limiting block 312 are rotatably mounted on the upper mounting component 3 via the first rotating ring 313, the positions of the first limiting block 311 and the second limiting block 312 can be adjusted with the rotation of the upper mounting component 3, and the included angle range between them can also be adjusted to meet various usage requirements. After the positions of the first limiting block 311 and the second limiting block 312 are adjusted, the first rotating ring 313 can be locked by the ring fixing component 314, thereby fixing the positions of the first limiting block 311 and the second limiting block 312.

[0040] The limiting pin 26 is detachably mounted on the fixed component 2. It can be removed when the angle limitation is not required.

[0041] Furthermore, the upper mounting component 3 is provided with a second rotating ring 261 rotatably connected thereto. The limiting pin 26 is fixedly connected to the second rotating ring 261 by a screw structure. The upper mounting component 3 is provided with a plurality of fixing holes 262 arranged in a ring array around its circumference. The limiting pin 26 is detachably connected to any of the fixing holes 262 by a pin fixing member. The pin fixing member is a screw structure, and the fixing hole 262 is a corresponding screw hole. Based on the above, since some dial and other components have polygonal surfaces, after grinding one side of the component using the above-mentioned directional grinding method with the limiting pin 26 and the limiting angle adjustment mechanism 31, in order to avoid repeatedly adjusting the position of the limiting angle adjustment mechanism 31 and improve the convenience of operation, the pin fixing component that is fixedly connected between the limiting pin 26 and the upper mounting part 3 can be directly disassembled. Then, the fixing part 2 is rotated, thereby driving the component set on the fixing part 2 to rotate together, so that the component switches to the next edge that needs to be ground. Then, the limiting pin 26 is fixed in the next corresponding fixing hole 262 by the pin fixing component, and the next side is ground, which makes the operation more convenient.

[0042] The working process of this utility model: In operation, this utility model discloses a multi-angle grinding auxiliary tool. The component to be ground is placed on the fixed surface outside each elastic block 22. Then, the control screw 23 is turned to move it. The second conical surface 241 and the first conical surface 221 cooperate to drive each elastic block 22 to unfold outwards. When unfolded, each elastic block 22 engages with the holes on the component to be ground, fixing it in place. The grinding equipment is then placed facing the fixed component 2. The angle adjustment mechanism adjusts the tilt angle of the fixed component 2 and the components mounted on it. The multi-angle grinding auxiliary tool is then moved to bring the components into contact with the grinding equipment for grinding. During grinding, the components can be rotated using the rotating drive component 4 to achieve uniform circumferential grinding. Alternatively, the fixed component 2 can be manually rotated to grind specific positions or angles, meeting various grinding needs.

[0043] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The internal components of the electric slide rail, cylinder, welding machine, electric telescopic rod and controller all adopt conventional models in the existing technology, and their internal structure belongs to the existing technology structure. Workers can complete the normal operation of them according to the existing technical manual. In addition, the circuit connection adopts the conventional connection method in the existing technology, and will not be described in detail here.

Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
