Detailed Implementation

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 3 As shown, this utility model provides a precision machining device for irregularly shaped surfaces of precision parts, including a mounting plate 11. A first motor 12 and a second motor 13 are mounted on the mounting plate 11. The first motor 12 is provided with a first gear 14 for adjusting the rotation angle. A transmission gear 15 for transmission is provided on the mounting plate 11. The transmission gear 15 is provided with a connecting gear for connecting different functions. The connecting gear includes an upper gear 16 and a lower gear 17. A connecting shaft is provided on the connecting gear. A machining frame 31 is provided on the connecting shaft. A sliding platform 18 is provided above the machining frame 31. A second gear 19 for adjusting the position of the sliding platform 18 is provided on the second motor 13. The second gear 19 meshes with the transmission gear 21. The transmission gear 15 is located between the first motor 12 and the second motor 13.

[0026] Specifically, the mounting plate 11 provides a stable support foundation for the entire device. The first motor 12 and the second motor 13 serve as power sources to drive the parts required for angle adjustment and position adjustment, respectively. The first gear 14 transmits the power of the first motor 12 to the connecting gear through its meshing relationship with the transmission gear 15, thereby realizing the rotation angle adjustment of the processing frame 31. The upper gear 16 and the lower gear 17 of the connecting gear correspond to different transmission functions, and the connecting shaft transmits the rotational motion of the connecting gear to the processing frame 31. The second motor 13 drives the sliding platform 18 to move through the second gear 19, which works with the processing frame 31 to realize multi-dimensional adjustment of the parts processing. The transmission gear 15 is located between the two motors to ensure that the transmission path does not deviate.

[0027] A connecting column is provided on the processing frame 31. A transmission gear 21 is sleeved on one side of the connecting column, and a first helical gear 22 is sleeved on the other side. The transmission gear 21 and the first helical gear 22 are separated by the processing frame 31 (the transmission gear 21 is located below the first helical gear 22). The transmission gear 21 meshes with the upper gear 16.

[0028] Specifically, the connecting column provides a mounting carrier for the transmission gear 21 and the first helical gear 22, enabling them to rotate coaxially. The transmission gear 21 meshes with the upper gear 16 of the connecting gear, transmitting the power of the connecting gear to the first helical gear 22. The vertical conversion of the gear's direction of rotation provides power for subsequent feed adjustment. The machining frame 31 serves as a dividing line to ensure that the upper and lower gears are arranged in an orderly manner, avoiding transmission interference.

[0029] A fixing block 23 is provided on the processing frame 31. The fixing block 23 is located on one side of the first helical gear 22. A transmission screw is provided on the fixing block 23. The transmission screw passes through the fixing block 23 and is mounted on the processing frame 31.

[0030] Specifically, the fixed block 23 provides support for the transmission screw, ensuring that it does not wobble during rotation; the transmission screw passes through the fixed block 23 and is connected to the processing frame 31, and can drive the processing frame 31 to move axially through rotational motion, thereby realizing the feed adjustment of the part processing and providing displacement control for the processing of irregular surfaces.

[0031] A second helical gear 24 is sleeved on the transmission screw. The second helical gear 24 is located on one side of the fixed block 23. The second helical gear 24 meshes with the first helical gear 22. Multiple sets of guide posts are passed through the processing frame 31. The processing frame 31 is sleeved on the multiple sets of guide posts and the transmission screw.

[0032] Specifically, the second helical gear 24 meshes with the first helical gear 22 to realize power steering transmission, converting the rotational power of the connecting column into the rotational motion of the transmission screw; the guide column plays a guiding and limiting role in the movement of the machining frame 31, and works with the transmission screw to ensure that the machining frame 31 moves smoothly along a straight line, avoiding deviation that affects machining accuracy.

[0033] like Figures 2 to 4 As shown, the processing frame 31 is provided with a fixing component for fixing the processing parts. The fixing component includes a clamping plate 25, which is connected to the processing frame 31 by bolts. The clamping plate 25 has a groove, and a rotating disk 26 is rotatably connected in the groove.

[0034] Specifically, the fixing component is used to clamp the parts to be processed. The clamping carrier plate 25 is detachably connected to the processing frame 31 by bolts, which makes it easy to change the appropriate clamping structure according to the size of the parts. The groove provides rotation space for the rotating disk 26. The rotation of the rotating disk 26 can drive the clamping components to move synchronously, so as to realize the rapid positioning and fixing of the parts.

[0035] The clamping carrier plate 25 is provided with multiple sets of guide rail plates 27. The multiple sets of guide rail plates 27 are arranged at equal intervals along the circular surface of the clamping carrier plate 25. Each set of guide rail plates 27 is provided with a clamping block 28. One end of each set of clamping blocks 28 is connected to the guide rail plate 27, and the other end is connected to the rotating disk 26.

[0036] Specifically, the guide rail plate 27 provides sliding guidance for the clamping blocks 28, and the equidistant arrangement ensures that the clamping force is evenly distributed; the clamping blocks 28, through their connection with the rotating disk 26, can move synchronously along the guide rail plate 27 as the rotating disk 26 rotates, thereby achieving concentric clamping of the parts and avoiding deformation or displacement of the parts caused by single-end force.

[0037] Both the rotating disk 26 and the clamping carrier plate 25 have limit holes, and limit pins are provided on the limit holes. Multiple sets of protective frames are provided on the mounting disk 11. The first motor 12 and the second motor 13 are located on the protective frames respectively. The bottom of the mounting disk 11 is provided with a pad post 29. A protective shell for protecting the internal structure is clamped on the mounting disk 11.

[0038] Specifically, the limiting hole and the limiting pin can lock the position of the rotating disk 26 to prevent the clamping block 28 from loosening during processing; the protective frame protects the motor to prevent processing debris or coolant from damaging the motor; the pad 29 is used to level the mounting plate 11 and supports the entire device. It can also be connected to other fixed structures to reduce vibration interference during equipment operation and ensure stable and reliable processing; the protective shell protects the internal instrument parts from external damage.

[0039] The specific usage and function of this embodiment are as follows:

[0040] When using this device, first place the mounting plate 11 on a flat surface in the processing area. Adjust the level using the bottom support 29 to reduce vibration and offset. Install the protective shell and frame to protect the first motor 12 and the second motor 13. At the same time, check the meshing of the first gear 14 with the transmission gear 15 and the second gear 19 with the drive gear 21 to ensure there is no jamming. Next, select a suitable clamping plate 25 according to the size of the part and fix it to the processing frame 31 with bolts. Rotate the rotating disk 26 to open the clamping block 28 along the guide rail plate 27. After placing the part, rotate the rotating disk 26 in the opposite direction to drive the block to clamp. Then, use the limit pin to rotate. The disk 26 is locked in place with the limiting hole of the clamping carrier plate 25; when adjusting the machining angle, the first motor 12 is started, and the power is transmitted to the connecting gear (upper gear 16 and lower gear 17) through the first gear 14 and the transmission gear 15. The connecting shaft drives the machining frame 31 to rotate and adjust the angle; the transmission gear 21 meshes with the upper gear 16 to transmit the power to the first helical gear 22, which meshes with the second helical gear 24 to drive the transmission screw to rotate, so that the machining frame 31 moves along the guide column axis to achieve displacement. This process is completed by starting the second motor 13, which meshes with the second gear 19 and the transmission gear 21 to drive the sliding stage 18 to move and complete the position adjustment.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
