DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides:

[0032] A variable angle chamfering device for NdFeB magnets comprises a rotating disk 1 and a driving mechanism for driving the rotating disk 1 to rotate. A mounting seat 2 distributed along its circumference is arranged at the bottom of the rotating disk 1. A chamfering seat 3 rotatably connected to the mounting seat 2 is arranged in the mounting seat 2. A chamfering head 4 and an adjusting rod 5 rotatably connected to the chamfering head 4 and longitudinally penetrating the mounting seat 2 are arranged on the chamfering seat 3. When the adjusting rod 5 moves longitudinally, the chamfering head 4 deflects longitudinally relative to the chamfering seat 3.

[0033] The rotating disc 1 serves as the base of the entire chamfering system and also supports the coordinated work between the driving mechanism and the plurality of mounting seats 2. The rotating disc 1 is designed to be sturdy and durable, and can stably support various dynamic loads during the entire processing process.

[0034] In order to drive the rotating disk 1 to achieve precise rotational motion, the driving mechanism accurately controls the speed and torque of the motor to smoothly transmit power to the rotating disk 1, so that it can rotate at a preset angle and speed. The high precision and reliability of the driving mechanism provide a solid foundation for the entire chamfering process.

[0035] At the bottom of the rotating disk 1, a plurality of mounting seats 2 are carefully arranged along its circumference. These mounting seats 2 not only provide stable support for the chamfering seat 3, but also realize flexible rotation connection with the chamfering seat 3. This connection mode allows the chamfering seat 3 to smoothly deflect when it is acted upon by the adjusting rod 5, thereby realizing precise adjustment of the chamfering angle.

[0036] Each mounting seat 2 is provided with a chamfering seat 3 which is closely matched therewith. The chamfering seat 3 is a key component for carrying a chamfering head 4. On the chamfering seat 3, a rotatable chamfering head 4 is installed.

[0037] In order to achieve precise adjustment of the chamfering angle, an adjustment rod 5 rotatably connected to the chamfering head 4 is provided on the chamfering seat 3. The adjustment rod 5 penetrates the mounting seat 2 in the longitudinal direction and cooperates with the mounting seat 2 through a precise sliding mechanism. When the adjustment rod 5 moves in the longitudinal direction, it transmits the motion to the chamfering head 4 through a specific transmission mechanism, so that the chamfering head 4 deflects in the longitudinal direction relative to the chamfering seat 3. This deflection motion is precisely controllable and can ensure that the chamfering head 4 reaches the desired angle position during the processing process.

[0038] In this embodiment, the chamfering seat 3 is designed as a rotatable structure and embedded in the mounting seat 2, so that the chamfering seat 3 can be flexibly rotated around a preset axis, thereby providing a wide angle adjustment space for the chamfering head 4 carried by it. Through the precise cooperation of the adjustment rod 5 and the mounting seat 2, the precise control of the rotation angle of the chamfering seat 3 is achieved.

[0039] Specifically, when the guide adjustment rod 5 is lifted and lowered relative to the mounting seat 2, its end will come into contact with a specific part of the chamfering seat 3 and exert a certain force. This force will serve as a driving force to guide the chamfering seat 3 to deflect according to a predetermined trajectory, thereby driving the chamfering head 4 installed therein to adjust the angle. Since the movement of the guide adjustment rod 5 is precisely controllable, the angle range that the chamfering head 4 can reach is also precise and predictable.

[0040] This design not only greatly simplifies the operation process of the variable angle chamfering machine, allowing operators to easily and quickly adjust the chamfering angle, but also significantly improves the processing accuracy and efficiency. Compared with traditional variable angle chamfering machines, this new type of equipment is more intuitive and convenient in operation, effectively solving the problems of cumbersome operation and difficult adjustment of previous equipment.

[0041] like Figure 7 , Figure 8 and Fig. 9 As shown, a connecting groove 31 extending along the length direction of the chamfered seat 3 is provided on the top thereof, and the bottom end of the adjusting rod 5 is slidably connected to the connecting groove 31 .

[0042] The bottom end of the adjusting rod 5 is provided with a pin extending along its radial direction, and both sides of the connecting groove 31 are provided with through holes extending along its length direction. The pin passes through the through holes and slides with them, so that when the adjusting rod 5 moves in the longitudinal direction, the chamfer seat 3 can be deflected due to the sliding connection between the adjusting rod 5 and the connecting groove 31.

[0043] When the operator needs to adjust the chamfering angle, he only needs to drive the adjusting rod 5 to move longitudinally through the corresponding control mechanism. The bottom end of the adjusting rod 5 will slide along the preset track under the guidance of the connecting groove 31, and at the same time drive the chamfering head 4 connected to it to deflect. Due to the precise guidance of the connecting groove 31 and the stable sliding of the adjusting rod 5, the whole adjustment process becomes very smooth and accurate.

[0044] like Figure 1 As shown, a height adjuster 6 is provided on the top of the rotating disk 1 . The height adjuster 6 has an adjusting plate 61 which can move in the longitudinal direction. The top end of the adjusting rod 5 is connected to the adjusting plate 61 .

[0045] The height adjuster 6 is installed at the top center of the rotating plate 1 , and the height adjuster 6 has an adjusting plate 61 that can move in the longitudinal direction.

[0046] The top end of the adjusting rod 5 is connected to the adjusting plate 61. This connection mode not only enables the adjusting rod 5 to be raised and lowered synchronously with the movement of the adjusting plate 61, but also ensures the stability of the adjusting rod 5 during the raising and lowering process. When the operator operates the height adjuster 6 through the control mechanism, the adjusting plate 61 moves longitudinally along a preset track, thereby driving the adjusting rod 5 and the chamfering head 4 connected thereto to adjust the height.

[0047] In this way, the operator can flexibly adjust the height of the chamfering head 4 according to the size, shape and processing requirements of the workpiece to achieve the best processing position. This height adjustment function not only improves the processing efficiency, but also ensures the stability and consistency of the processing quality.

[0048] In addition, the height adjuster 6 works in coordination with the rotating disk 1 , the mounting seat 2 , the chamfering seat 3 , the adjusting rod 5 and other components to form an efficient, precise and flexible chamfering processing system.

[0049] like Figure 4 and Figure 5 As shown, the rotating disk 1 is provided with a moving seat 11 which can move along its radial direction, the mounting seat 2 is arranged at the bottom of the moving seat 11, the adjusting rod 5 slides through the moving seat 11, and an adjusting disk 7 is also arranged on the top of the rotating disk 1. The adjusting disk 7 is provided with an adjusting groove 71 which deviates from its radial direction, the adjusting rod 5 penetrates the adjusting groove 71, and the adjusting plate 61 is provided with a sliding groove 611 which extends along the radial direction of the rotating disk 1, and the top end of the adjusting rod 5 slides in cooperation with the sliding groove 611.

[0050] The design of the movable seat 11 allows the mounting seat 2 and the chamfering seat 3 and the chamfering head 4 thereon to be adjusted in the radial direction of the rotating disk 1, thereby adapting to the processing requirements of workpieces of different sizes and shapes.

[0051] The moving seat 11 is mounted on the rotating disk 1, and radial movement is achieved through the precise adjustment disk 7 and the rotating disk 1. This sliding mechanism not only ensures the stability and accuracy of the moving seat 11 during movement, but also enables the operator to easily adjust the position of the moving seat 11. The mounting seat 2 is firmly set at the bottom of the moving seat 11, and moves synchronously with the movement of the moving seat 11, ensuring that the relative position between the chamfering head 4 and the workpiece is always accurate.

[0052] The adjusting rod 5 not only slides through the moving seat 11, but also cooperates with the adjusting groove 71 on the adjusting disk 7 at the top of the rotating disk 1. The design of the adjusting groove 71 deviates from the radial direction of the adjusting disk 7. When the adjusting disk 7 rotates relative to the rotating disk 1, the inclined adjusting groove 71 can guide the moving seat 11 to move along its radial direction on the rotating disk 1, so that the positions of all the chamfering heads 4 can be adjusted, which is convenient for adapting to the processing of magnetic rings with different diameters.

[0053] At the same time, a sliding groove 611 extending radially along the rotating disk 1 is newly added to the adjustment plate 61. This allows the top end of the adjustment rod 5 to slide with the sliding groove 611, further enhancing the stability and accuracy of the adjustment rod 5 during the longitudinal movement. When the operator operates the height adjuster 6 through the control mechanism, the adjustment plate 61 will move longitudinally along a preset trajectory, and then drive the adjustment rod 5 and the chamfering head 4 connected thereto to adjust the height through the sliding groove 611. At the same time, due to the cooperation between the adjustment rod 5 and the adjustment groove 71, the chamfering head 4 can also be fine-tuned in the radial direction to meet the processing requirements of different workpieces, and the sliding groove 611 can facilitate the adjustment rod 5 to move at the same height.

[0054] like Figure 4 and Figure 5 As shown, the abutting surfaces of the adjusting disk 7 and the rotating disk 1 are also provided with a locking structure 81 that can be engaged along the longitudinal direction, and an elastic pressure element 82 is provided on the top of the rotating disk 1 , and the adjusting disk 7 is locked with the rotating disk 1 under the action of the elastic pressure element 82 .

[0055] To ensure that the relative positions of the two can remain stable during the processing, a locking structure 81 that can be engaged in the longitudinal direction is designed on the abutting surfaces of the adjusting disk 7 and the rotating disk 1 .

[0056] The locking structure 81 is composed of processed protrusions and grooves, which are respectively located on the contact surfaces of the adjusting disk 7 and the rotating disk 1. When the adjusting disk 7 and the rotating disk 1 are tightly fitted, these protrusions will accurately fit into the corresponding grooves to form a firm locking connection. This locking method is not only simple and effective, but also can withstand large torque and impact force, ensuring that the adjusting disk 7 and the rotating disk 1 will not be relatively displaced due to external forces during the processing.

[0057] In order to further enhance the locking effect, an elastic pressure element 82 is also provided on the top of the rotating disk 1. These elastic pressure elements 82 are usually made of highly elastic materials, such as springs or elastic washers, etc., which can generate continuous elastic force to press the adjustment disk 7 tightly against the rotating disk 1. Under the action of the elastic pressure element 82, the locking between the adjustment disk 7 and the rotating disk 1 is more stable and reliable, and a stable connection state can be maintained even in a long-term, high-load processing process.

[0058] At the same time, when the adjusting disk 7 is moved upward relative to the rotating disk 1, the adjusting disk 7 can overcome the elastic force of the elastic pressure element 82 and move upward, so that the protrusion and the groove are separated, and then the adjusting disk 7 can rotate relative to the rotating disk 1, thereby adjusting the rotation diameter of the chamfering head 4.

[0059] like Figure 6 and Figure 7 As shown, a connecting sleeve 111 coaxial with the adjusting rod 5 is provided at the bottom of the movable seat 11 , and the connecting sleeve 111 is rotatably connected to the mounting seat 2 , and a locking device 21 capable of locking with the movable seat 11 is provided in the mounting seat 2 .

[0060] The bottom of the moving seat 11 is provided with a connecting sleeve 111 coaxial with the adjusting rod 5. This connecting sleeve 111 not only serves as a connecting bridge between the moving seat 11 and the adjusting rod 5, but also undertakes the important task of transmitting the rotational motion of the moving seat 11 to the mounting seat 2.

[0061] The connecting sleeve 111 and the mounting seat 2 are connected in a rotating manner, which allows the mounting seat 2 to rotate relative to the rotating seat, thereby adjusting the grinding direction of the chamfering head 4, thereby achieving the ability to grind the inner and outer edges of the magnetic ring.

[0062] A locker 21 that can be locked with the moving seat 11 is also provided in the mounting seat 2. When the mounting seat 2 needs to be rotated, the mounting seat 2 can be rotated at the bottom of the moving seat 11 by releasing the lock between the mounting seat 2 and the moving seat 11, thereby adjusting the grinding direction of the chamfering head 4. After the locker 21 is locked with the moving seat 11, the mounting seat 2 and the moving seat 11 cannot rotate relative to each other, thereby preventing the mounting seat 2 from accidentally moving or rotating relative to the moving seat 11.

[0063] like Figure 3 and Fig.10As shown, the bottom end of the movable seat 11 is provided with locking holes 112 symmetrically arranged on both sides of the adjusting rod 5, and the locker 21 includes a locking pin 211 that slides through the mounting seat 2 along the longitudinal direction, and the bottom end of the locking pin 211 is provided with a locking block 212 that slides in the mounting seat 2 along the longitudinal direction, and one side of the locking block 212 is provided with an inclined surface, and one side of the mounting seat 2 is provided with a bolt 214 threadedly connected thereto, and the inner end of the bolt 214 abuts against the inclined surface of the locking block 212.

[0064] In order to enhance the controllability and stability of the locking pin 211, a locking block 212 is provided at the bottom end of the locking pin 211. The locking block 212 is slidably arranged in the mounting seat 2 along the longitudinal direction, and forms a linkage relationship with the locking pin 211. One side of the locking block 212 is designed with an inclined surface.

[0065] On one side of the mounting seat 2, a bolt 214 is provided which is threadedly connected thereto. This bolt 214 not only exists as an adjustment element, but also directly participates in the locking process. When it is necessary to lock the movable seat 11, the operator can rotate the bolt 214 so that its inner end gradually abuts against the inclined surface of the locking block 212. As the bolt 214 is further tightened, its inner end will apply an upward pressure along the inclined surface of the locking block 212. This pressure will push the locking block 212 to slide upward along the mounting seat 2, thereby driving the locking pin 211 to move upward until its bottom end is fully inserted into the locking hole 112 of the movable seat 11.

[0066] At this time, under the close cooperation between the locking pin 211 and the locking hole 112, the movable seat 11 is firmly locked on the mounting seat 2. Even in the face of strong vibration or impact force, this locking structure 81 can remain stable and reliable, ensuring the smooth progress of the processing process.

[0067] In addition, the lock 21 has the advantages of being easy to operate and maintain. The operator can complete the locking and unlocking operations by simply rotating the bolt 214, without using complicated tools or performing tedious disassembly work. At the same time, since all components are designed with reasonable maintenance space, it is also very convenient for daily maintenance and repair.

[0068] After the relative angle between the mounting seat 2 and the moving seat 11 is adjusted, they are locked by the locking device 21 .

[0069] like Figure 6 and Figure 7 As shown, an elastic reset element 213 is provided between the locking block 212 and the top end of the inner cavity of the moving seat 11 .

[0070] The elastic reset element 213 is usually made of a spring or elastic material, and has good elasticity and durability. One end of the elastic reset element 213 is fixed to the top of the inner cavity of the movable seat 11, and the other end is connected to the locking block 212. When the locking block 212 is pushed upward by the bolt 214, the elastic reset element 213 will be compressed and store energy. Once the bolt 214 is loosened and no upward pressure is applied to the locking block 212, the elastic reset element 213 will quickly release the stored energy, pushing the locking block 212 to slide upward along the mounting seat 2 until it is completely restored to its initial position.

[0071] The introduction of the elastic reset element 213 not only simplifies the locking and unlocking operation process, but also improves the reliability and stability of the locking mechanism. It ensures that the locking block 212 can be accurately reset after each unlocking, avoiding locking failure or equipment failure caused by the position deviation of the locking block 212.

[0072] In addition, the elastic reset element 213 also has a certain buffering effect. During the locking or unlocking process, if it is subjected to external impact or vibration, the elastic reset element 213 can absorb part of the energy and reduce the damage to the locking block 212 and the moving seat 11. This design not only prolongs the service life of the equipment, but also improves the safety and stability of the processing process.

[0073] like Figure 3 As shown, a connector 62 is provided on the top of the rotating disk 1 for transmission connection with the output shaft of the driving mechanism, a guide column 63 and a threaded column 64 are provided between the connector 62 and the rotating disk 1, the guide column 63 and the threaded column 64 slide through the adjustment plate 61, and an adjustment cylinder 65 is provided on the adjustment plate 61 for rotation connection therewith, and the adjustment cylinder 65 is coaxially threadedly connected with the threaded column 64.

[0074] In order to achieve stable connection and efficient transmission between the connector 62 and the rotating disk 1, two key components, a guide column 63 and a threaded column 64, are arranged between the two. The guide column 63 mainly plays a guiding and supporting role, which ensures that the connector 62 can maintain a stable motion trajectory during the power transmission process to avoid deviation or shaking.

[0075] The guide column 63 and the threaded column 64 both slide through the adjustment plate 61. An adjustment cylinder 65 is provided on the adjustment plate 61 and is rotatably connected thereto. The adjustment cylinder 65 has a thread structure coaxial with the threaded column 64 and matched with each other. When the adjustment cylinder 65 rotates, it can push or pull the adjustment plate 61 to move longitudinally through the meshing action of the thread.

[0076] In this way, the operator can precisely control the position of the adjustment plate 61 by rotating the adjustment cylinder 65 , thereby achieving fine adjustment of the angle of the chamfering head 4 .

[0077] like Figure 4 and Figure 5 As shown, the diameter of the adjusting disk 7 is larger than the diameter of the rotating disk 1 , and grooves distributed along the circumference of the adjusting disk 7 are arranged on the outer circumferential surface.

[0078] The diameter of the adjusting disk 7 is larger than that of the rotating disk 1 , and the adjusting disk 7 can be moved upward through the edge of the adjusting disk 7 . Meanwhile, the groove can facilitate the operator to manually operate the angle of the adjusting disk 7 relative to the rotating disk 1 .

[0079] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
